Mercedes-Benz S-CLASS SEDAN 2023 Active Blind Spot Assist With Exit Warning User Manual
Active Blind Spot Assist With Exit Warning
The function of Active Blind Spot Assist with exit warning
Active Blind Spot Assist uses radar sensors to monitor the area up to 130 ft (40 m) behind and 10 ft (3 m) next to your vehicle.
The system can detect vehicles traveling at speeds of approximately 8 mph (12 km/h) and issue a warning if they move into the monitoring range.
Status display in the driver’s display
- Gray: the system is activated but inoperative.
- Green: the system is activated and operational.
Driver display in the Assistance menu
If a vehicle is detected within the monitoring range, the red warning lamp lights up in the corresponding outside mirror. In the Assistance menu, the lamp in outside mirror 1 also lights up red, and the lane in which the vehicle is detected is hatched out.
If a vehicle is detected in the monitoring range and you switch on the turn signal indicator in the corresponding direction, a warning tone sounds twice and the warning lamp flashes red in the respective outside mirror. Red radar waves 2 are displayed next to your vehicle in the assistance graphic.
If the turn signal indicator remains on, the display in the outside mirror flashes for all other detected vehicles, but no further warning tone sounds. If you overtake a vehicle quickly, no warning is given. Vehicles with active ambient lighting: if Warning Support is activated, the Active Blind Spot Assist warning is also accompanied by ambient lighting (/ page 174). Observe the notes on driving systems and your responsibility; you may otherwise fail to recognize dangers (/ page 252).
Blind Spot Assist
Active Blind Spot Assist does not react to the following:
- If you overtake a vehicle too closely so that it is in the blind spot area
- If vehicles traveling at a much faster speed approach and then overtake
Active Blind Spot Assist may not give warnings or intervene in such situations.
- Always pay careful attention to the traffic situation and maintain a safe distance at the side of the vehicle.
Exit warning
The exit warning is an additional function of Active Blind Spot Assist and can warn vehicle occupants attempting to leave the stationary vehicle about approaching vehicles.
WARNING
Risk of the accident despite exit warning
The exit warning neither reacts to stationary objects nor to persons or road users approaching you at a greatly differing speed.
The exit warning cannot warn drivers in these situations. Always pay particular attention to the traffic situation when opening the doors and make sure there is sufficient clearance.
If a vehicle is detected in the monitoring range, the red warning lamp lights up in the corresponding outside mirror.
If a vehicle occupant pulls the door handle on the side of the warning, a warning tone sounds twice, and the ambient lighting in the respective door and the warning lamps in the corresponding outside mirror flash red. Vehicles with MBUX Interior Assistant: the visual warning begins as soon as the hand of a vehicle occupant moves into the area of the door. Vehicles with ambient lighting or active ambient lighting: the Warning Support of the ambient lighting can be activated and deactivated ( page 174). The warning assistance can differ depending on the equipment and may vary according to the setting.
The exit warning is only available when Blind Spot Assist is active.
After the vehicle is switched off, the exit warning continues to function for a few minutes. When the outside mirror warning light flashes three times, the exit warning is no longer available. The exit warning is only an aid and not a substitute for the attention of vehicle occupants. The responsibility for opening and closing the doors and for leaving the vehicle remains with the vehicle occupants.
System limits
Active Blind Spot Assist may be limited in the following situations, in particular:
- if there is dirt on the sensors or the sensors are obscured
- In poor visibility, e.g. due to fog, heavy rain or snow
- If there are narrow vehicles, e.g. bicycles or motorbikes
- If the road has very wide or narrow lanes
- If vehicles are not driving in the middle of their lane
Warnings may be issued in error when driving close to crash barriers or similar continuous lane borders. Always make sure that there is sufficient distance to the side for other traffic or obstacles.
Warnings may be interrupted when driving along-side long vehicles, for example trucks, for a pro-longed time. Active Blind Spot Assist is not operational when reverse gear is engaged.
Additionally, the exit warning may be limited in the following situations:
- When the sensors are covered by adjacent vehicles in narrow parking spaces
- When people approach the vehicle
- In the event of stationary or slowly moving objects
- The function of the brake application of Active Blind Spot Assist
If Active Blind Spot Assist detects a risk of a side impact in the monitoring range, a course-correcting brake application is carried out. This is designed to help you avoid a collision.
The course-correcting brake application is available in the speed range between approximately 20 mph (30 km/h) and approximately 125 mph (200 km/h).
WARNING
Risk of the accident despite brake application of Active Blind Spot Assist
Always maintain a safe distance at the sides.
If a course-correcting brake application occurs, the red warning lamp flashes in the outside mirror, and a warning tone sounds. In addition, display 1 indicating the danger of a side collision appears in the driver’s display. In rare cases, the system may make an inappropriate brake application. This brake application may be interrupted at any time if you steer slightly in the opposite direction or accelerate.
System limits
Either a course-correcting brake application appropriate to the driving situation, or none at all, may occur especially in the following situations:
- Vehicles or obstacles, e.g. crash barriers, are located on both sides of your vehicle.
- A vehicle approaches too closely on the side.
- You have adopted a sporty driving style with high cornering speeds.
- You brake or accelerate significantly.
- A driving safety system intervenes, e.g. ESP® or Active Brake Assist.
- ESP® is deactivated.
- A loss of tire pressure or a defective tire is detected.
