2021-2023 Citroen C4 Lights and Wipers Guidelines

The Citroen C4 is a beautiful and modern small automobile that has cutting-edge lighting and wiper technologies that are intended to improve both safety and aesthetics. It will be available from 2021 to 2023. We’ll delve into the cutting-edge features of the Citroen C4’s lighting and wiper systems in this introduction. Modern LED headlights and taillights are part of the Citroen C4’s lighting system, which not only increase visibility when driving at night but also give the car’s exterior a unique, upscale look. These lights frequently have adaptive features like dynamic cornering lights and automated high beams to provide the best illumination under diverse driving circumstances.

A rain-sensing intelligent wiper system is another feature of the Citroen C4. Even in torrential downpours, these wipers automatically alter their speed and strength according on the amount of precipitation, giving drivers a clear view of the road. By decreasing distractions and enabling drivers to concentrate on the road ahead, this function improves safety. We will go through the technology underlying the lighting and wiper systems on the Citroen C4 2021-2023, as well as their advantages and how they contribute to a better driving experience.

Lighting Control Stalk Main Lighting

• Automatic illumination of lamps/daytime running lamps
• Sidelamps only
• Dipped or main beam headlamps

Headlamp dipping

Pull the lighting control stalk to switch between dipped and main beam headlamps. In “AUTO” and sidelamps mode, pull the lighting control stalk to switch the main beam headlamps on directly (“headlamp flash”).
Display
Illumination of the corresponding indicator lamp on the instrument panel confirms that the selected lighting is on. A fault with a lamp is signalled by the  permanent illumination of this warning lamp, accompanied by the display of a message and an audible signal.

Rear foglamp
It only works if the dipped or main beam headlamps are on.

• Rotate the ring forwards/backwards to turn it on/off.
  When the lighting is switched off automatically (“AUTO” position) the foglamp and the sidelamps remain on.

Front foglamps/Rear foglamp
They operate with the sidelamps, dipped or main beam headlamps on.

• Rotate the ring forwards:
  • once to switch on the front foglamps,
  • a second time to switch on the rear foglamp.
•  Turn in the opposite direction to switch off. If the lighting is switched off automatically (“AUTO” position) or the dipped beam headlamps are switched off manually, the foglamps and sidelamps remain on.
• Rotate the ring backwards to switch the foglamps off; the sidelamps will then switch off.

Switching on the foglamps is prohibited in clear weather or in rain, both day and night. In these situations, the power of their beams may dazzle other drivers. They must only be used in fog or falling snow (rules may vary depending on country). Do not forget to switch off the foglamps when they are no longer necessary. Switching off of the lighting when the ignition is switched off  When the ignition is switched off, all of the lamps turn off immediately, except for the sidelamps and the dipped beam headlamps if automatic guide-me-home lighting is activated.
Switching on the lamps after switching off the ignition
To reactivate the lighting control, rotate the ring to the “AUTO” position, then to the desired position.
If the driver’s door is opened, a temporary audible signal warns the driver that the lamps are on.
They will go off automatically after a period of time that depends on the level of charge in the battery (entering energy economy mode).
In some weather conditions (e.g. low
temperature or humidity), misting on the internal surface of the glass of the headlamps and rear lamps is normal, and will disappear after the lamps have been on for a few minutes.
Never look too closely at the light beam of LED technology lamps – risk of serious eye injury!

Travelling abroad
If planning to use your vehicle in a country that drives on the other side of the road, the dipped beam headlamps must be adjusted to avoid dazzling oncoming drivers. Contact a CITROËN dealer or a qualified workshop.

Daytime running lamps/ Sidelamps
These LED lamps at the front and rear of the vehicle light up automatically when the engine starts.
They perform the following functions:

• Daytime running lamps (lighting control stalk at position “AUTO” with adequate ambient light).
• Sidelamps (lighting control stalk at position
  “AUTO” with low ambient light or “Sidelamps only” or “Dipped/main beam headlamps”).

Direction indicators

Left or right: lower or raise the lighting control stalk, beyond the point of resistance.
If you keep the direction indicators on for more than 20 seconds, the volume of the audible signal will increase if the speed is above 50 mph (80 km/h).

Three flashes
Press briefly upwards or downwards, without going beyond the point of resistance; the direction indicators will flash 3 times.

Parking lamps (Depending on version)
Vehicle side marking by lighting the sidelamps on the traffic side only.

• Within one minute after switching off the ignition, operate the lighting control stalk upwards or downwards, depending on the side of the traffic (e.g. when parking on the right, push the lighting control stalk down to light up on the left).
  This is confirmed by an audible signal and the lighting of the corresponding direction indicator lamp on the instrument panel.
• To switch off the parking lamps, return the lighting control stalk to the central position.

Automatic Illumination of Lamps

With the lighting control stalk in the “AUTO” position and if a low level of exterior brightness is detected by the rain/sunshine sensor, the sidelamps and dipped beam headlamps are switched on automatically, without any action on the part of the driver. They may also come on if rain is detected, at the same time as automatic operation of the windscreen wipers.
As soon as the brightness returns to a sufficient level or after the windscreen wipers are switched off, the lamps are switched off automatically.

Malfunction
In the event of a malfunction of the rain/sunshine sensor, the vehicle’s lamps
come on and this warning lamp is displayed on the instrument panel, accompanied by an audible signal and/or the display of a message.
Have it checked by a CITROËN dealer or a qualified workshop.
Do not cover the rain/sunshine sensor located at the top centre of the windscreen behind the interior rear view mirror; the associated functions would no longer be controlled.
In fog or snow, the rain/sunshine sensor may detect sufficient light. For this reason, the lighting will not come on automatically.
The inner surface of the windscreen may become misted up and affect the proper operation of the rain/sunshine sensor.
In humid and cold weather, demist the windscreen regularly.

Headlamp Beam Height Adjustment

To avoid dazzling other road users, the height of these headlamp beams must be adjusted according to the load in the vehicle.

• (Initial setting) Driver only or driver + front passenger
• 5 people
• people + load in the boot
  Driver only + load in the boot
• Not used

Guide-me-home and Welcome lighting

Guide-me-home lighting Automatic
With the ring of the lighting control stalk in the “AUTO” position and when the light is poor, the sidelamps and dipped beam headlamps come on automatically when the ignition is switched off.
You can activate/deactivate this function and adjust the guide-me-home lighting duration in the Driving/Vehicle touch screen menu.

With the ignition off, pull the lighting control stalk toward you (“headlamp flash”) to activate/deactivate the function.
Manual guide-me-home lighting goes off automatically after a period of time.

Welcome lighting
When the vehicle is unlocked, if the ambient light is low and the “Automatic illumination of headlamps” function is activated, this system automatically turns on certain exterior lamps as well as certain lamps in the passenger compartment.
You can activate/deactivate this function and adjust the welcome lighting duration in the Driving / Vehicle touch screen tablet menu.

Door mirror spotlamps
These spotlamps facilitate access to the vehicle by lighting the ground near the front doors.
When the front courtesy lamp switch is in this position, the spotlamps come on automatically:

• when the vehicle is unlocked.
  when a door is opened.
• when a request to locate the vehicle is received from the remote control.

Whatever the position of the front courtesy lamp switch, they also come on with the welcome lighting and guide-me-home lighting functions. They go off automatically after 30 seconds.

Automatic lighting Systems – General Recommendations

The automatic lighting systems use a detection camera, located at the top of the windscreen.

Operating limits
The system may be disrupted or not work correctly:

• When visibility conditions are poor (e.g. snowfall, heavy rain).
• If the windscreen is dirty, misted-up or masked (e.g. sticker) in front of the camera.
• If the vehicle is facing highly reflective signs or safety barrier reflectors.

The system is not able to detect:

• Road users that do not have their own lighting, such as pedestrians.
• Vehicles with hidden lighting (e.g. travelling behind a safety barrier on the motorway).
• Vehicles at the top or bottom of a steep slope, on winding roads, on crossroads.

Maintenance
Clean the windscreen regularly, particularly the area in front of the camera.
The internal surface of the windscreen can also become misted around the camera. In humid and cold weather, demist the windscreen regularly.Do not allow snow to accumulate on the bonnet or roof of the vehicle as this could obstruct the camera.

Automatic headlamp dipping
For more information, refer to the General recommendations for automatic lighting systems.
With the ring of the lighting control stalk in the “AUTO” position and the function activated on the touch screen, this system automatically switches between dipped and main beam headlamps, according to lighting and traffic conditions, using a camera located at the top of the windscreen.

This system is a driving aid. The driver remains responsible for
the vehicle’s lighting, its correct use in the prevailing light, visibility and traffic conditions, and for compliance with driving and vehicle regulations.
The system becomes operational when the vehicle exceeds 16 mph (25 km/h). When the speed falls below 9 mph (15 km/h), the function is no longer operational.

Activation/Deactivation
It is set via the Driving / Vehicle touch screen menu. The state of the system stays in the memory when switching off the ignition.
Operation
If the ambient light level is very low and traffic conditions permit:

The main beam headlamps come on automatically. These indicator lamps light up on the instrument panel. If the ambient light level is sufficient and/or the traffic conditions do not allow the main beam headlamps to be lit:

The dipped beam headlamps remain lit. These indicator lamps light up on the instrument panel.

The function is deactivated if the foglamps
are switched on or if the system detects poor visibility conditions (e.g. fog, heavy rain, snowfall).
When the foglamps are switched off or when the visibility conditions become favourable again, the function is automatically reactivated.

This indicator lamp goes out when the function is deactivated

Pause
If the situation requires a change of headlamp beam, the driver can take over at any time.\

• Switch the headlamps manually between dipped and main beam to pause the function. If the “AUTO” and “Dipped beam” indicator lamps were on, the system changes to main beam. If the “AUTO” and “Main beam” indicator lamps were on, the system changes to dipped beam.\
• To reactivate the function, once again switch the headlamps manually between dipped and main beam.

Malfunction
If a malfunction occurs with the system or the camera, this warning lamp lights up on the instrument panel, accompanied by an audible signal and a message.
Have it checked by a CITROËN dealer or a qualified workshop.

Cornering lighting

This system makes use of the beam from a front foglamp to illuminate the inside of a bend, when the main or dipped beam headlamps are on and the vehicle speed is below 25 mph (40 km/h)
(urban driving, winding road, junctions, parking manoeuvres).

Without/With cornering lighting

Activation / Deactivation

Switching on/off
This system starts:

• when the corresponding direction indicator is switched on. or
• from a certain angle of rotation of the steering wheel. It becomes inactive:
• below a certain angle of rotation of the steering wheel.
• above approximately 25 mph (40 km/h).
• when reverse gear is engaged.

Wiper control stalk

Before operating the wipers in wintry conditions, clear any snow, ice or frost from the windscreen and around the wiper arms and blades.
Do not operate the wipers on a dry
windscreen. In extremely hot or cold weather, check that the wiper blades are not stuck to the windscreen before operating the wipers.
After using an automatic car wash, you may temporarily notice abnormal noises and poorer wiping performance. You do not need to replace the wiper blades.

With intermittent wipers

With automatic Wipers

Windscreen wipers

• To select the wiping speed: raise or lower the stalk to the desired position.
  Fast wiping (heavy rain)
  Normal wiping (moderate rain)
  Intermittent wipers
  Automatic wipers
  Switching off
  Manual

In position 1 or 2, the wiping frequency is automatically reduced when the speed of the vehicle drops below 3 mph (5 km/h). When the speed is above 6 mph (10 km/h) again, the wiping frequency returns to the original frequency (fast or normal).

Single wipe
Press and release the control stalk or briefly pull the control stalk towards you.

Windscreen wash
Pull the wiper control stalk towards you and hold.
A final wiping cycle is performed when screen washing ends.
With automatic air conditioning, any action on the screen wash control results in temporary closure of the air intake to protect the passenger compartment from any odour.

To avoid damaging the wiper blades, do not operate the screenwash if the screenwash reservoir is empty.
Only operate the screenwash if there is no risk of the fluid freezing on the windscreen and hindering visibility. During the winter period, use “very cold climate” rated products. Never top up with water.

 In Intermittent mode, the driver can adjust the wiping frequency by turning the ring to one of the 5 available positions.

The first (upper) position corresponds to the longest time interval between 2 wipes for light rain.
The last (lower) position corresponds to the shortest time interval between 2 wipes for heavy rain.
A rotation of the ring from a higher position to a lower position triggers a confirmation wiping.
After the ignition has been switched off for more than 1 minute with the wiper control stalk in the INT, 1 or 2 position, when the ignition is switched on again:

•  the system works as soon as the vehicle exceeds 6 mph (10 km/h), if the outside temperature is below +3°C.
• the system works immediately, if the outside temperature is above +3°C.

Automatic windscreen wipers
In AUTO mode, the front wipers work automatically and adapt to the intensity of precipitation depending on the sensitivity of the sensor selected.
The rainfall detection function uses a rain/sunshine sensor located at the top centre of the windscreen, behind the rear view mirror.

In certain weather conditions (e.g. fog, frost, snow, projections on salty roads), the driver may have to return to manual wiping.

Switching on/off
To switch on:

• Put the wiper control stalk in the AUTO position.
• Turn the ring to adjust the sensitivity of the sensor.

A wiping cycle, accompanied by the display of a message, confirms that the request has been taken into account.

• To switch off, put the wiper control stalk in another position or in the 0 position.

Adjusting the sensitivity

The first position (upper) corresponds to the lowest sensitivity of the sensor.
The last position (lower) corresponds to the highest sensitivity of the sensor.
The higher the sensitivity, the faster the system reacts and increases the wiping frequency.
A rotation of the ring from a higher position to a lower position triggers a confirmation wiping.
After the ignition has been switched off for more than 1 minute with the wiper control stalk in the AUTO position, when the ignition is switched on again:

• The system works, depending on the volume of rain detected, as soon as the vehicle exceeds 6 mph (10 km/h), if the outside temperature is below +3°C.
  The system works immediately, depending on the volume of rain detected, if the outside temperature is above +3°C.

Do not cover the rain/sunshine sensor. When using an automatic car wash, switch off the automatic wipers and the ignition. In winter, wait until the windscreen is completely clear of ice before activating the automatic wipers.

Malfunction
If a fault occurs with the automatic wipers, the wipers operate in intermittent mode.
Have it checked by a CITROËN dealer or a qualified workshop.
Special position of the
windscreen wipers
This maintenance position is used while cleaning or replacing the wiper blades. It can also be useful, in wintry weather (ice, snow), to release the wiper blades from the windscreen.
To maintain the effectiveness of the flat wiper blades, it is advisable to:

• handle them with care.
• clean them regularly using soapy water.
• avoid using them to hold cardboard on the windscreen.
• replace them at the first signs of wear.

Before removing a windscreen wiper blade

Operating the wiper control stalk immediately after switching off the ignition will place the wiper blades in a vertical position.

• Proceed with the desired operation or the replacement of the wiper blades.

After refitting a windscreen wiper blade

• To return the wiper blades to their initial position after the operation, switch on the ignition and operate the wiper control stalk.

Changing a wiper blade
Removing/Refitting at the front

• Carry out these wiper blade replacement operations from the driver’s side.
• Starting with the wiper blade farthest from you, hold each arm by the rigid section and raise it as far as possible.
• Do not touch the wiper blades – risk of irreparable deformation.
• Do not release them while moving them. Risk of damaging the windscreen!
• Clean the windscreen using screen wash fluid.
• Do not apply “Rain X” type water-repellent products.
• Unclip the worn wiper blade closest to you and remove it.
• Install the new wiper blade and clip it to the arm.
• Repeat the procedure for the other wiper blade.
• Starting with the wiper blade closest to you, once again hold each arm by the rigid section, then guide it carefully onto the windscreen.
