Aston Martin DBX 2021 Adaptive Cruise Control (ACC) with Speed Limiter User Manual
The 2021 Aston Martin DBX is a luxurious SUV that features advanced technology, performance, and style. One of its notable features is the cruise control system that enables drivers to maintain a constant speed without frequently using the throttle. The DBX’s cruise control system is designed to provide a smooth and comfortable driving experience, and it can be activated and adjusted using the controls on the steering wheel. The system also includes adaptive cruise control, which uses sensors to detect the distance from the vehicle ahead and maintain a safe following distance. This feature can be helpful for reducing driver fatigue during long journeys and making highway driving more relaxing. Moreover, the DBX’s cruise control system can be customized according to the driver’s preference, such as adjusting the acceleration and deceleration sensitivity. In summary, the Aston Martin DBX’s cruise control system is an essential feature that enhances the driving experience, making it easier for drivers to maintain a constant speed while on the road.
Adaptive Cruise Control (ACC) with Speed Limiter
Warning: Only use ACC or the variable speed limiter if road and traffic conditions are appropriate for maintaining a steady speed for a prolonged period. If you do not, the vehicle may cause an accident or collision resulting in death or serious injury.
Warning: Both ACC and the variable speed limiter are aids and cannot take into account road, weather or traffic conditions. You are responsible for vehicle speed, braking, controlling the distance to any vehicle(s) in front and for staying in the correct lane.
The ACC system should not be used when:
- Road and traffic conditions do not allow you to maintain a constant speed, e.g. in heavy traffic or on winding roads.
- Driving on smooth or slippery roads. Braking or accelerating can cause the drive wheels to lose traction and the vehicle could then skid.
- Visibility is poor, such as fog, heavy rain or snow.
Selecting ACC or Variable Speed Limiter
- ACC/VARIABLE SPEED LIMITER SELECT: Press switch between Adaptive Cruise Control (ACC) and variable speed limiter function.
- SPEED SET ROCKER SWITCH: Push up to increase or down to decrease the set speed for the ACC or variable speed limiter. Press the rocker switch to resume the set speed.
- CAN: Press to cancel the set speed.
- INCREASE DISTANCE: Increases the set distance between the vehicle in front and your vehicle.
- DECREASE DISTANCE: Decreases the set distance between the vehicle in front and your vehicle.
Operation
ACC can be used to maintain a selected vehicle speed without having to use the accelerator and maintains a set distance between your vehicle and the vehicle in front of you.
The variable speed limiter brakes automatically so that you do not exceed the set speed. This feature is an aid only and cannot take into account road, weather or traffic conditions. You are responsible for vehicle speed, as well as braking in good time and for staying in the lane.
Both ACC and variable speed limiter only operate at speeds above 20 km/h (13 mph).
Setting A Speed
Lightly push the speed selector switch (2) up to increase speed, or down to decrease speed in 1 km/h (1 mph) increments. A hard press in either direction will increase in 10 km/h (5mph) increments. Pressing the switch in either direction will set a new vehicle speed in the cruise control or new vehicle speed limit.
ACC will automatically disengage when the brake pedal is pressed or when the vehicle speed falls below 20 km/h (13 mph).
The variable speed limiter is not deactivated when the brake pedal is pressed.
Resuming the Set Speed
Warning: Set speed should only be resumed if the driver is aware of the set speed and intends to return to it.
ACC will not resume at speeds below 20 km/h (13 mph).
Press the speed selector switch (2) to resume the set ACC speed or variable speed limit. If the vehicle is accelerated above the set speed, then the set ACC speed will be resumed when the accelerator pedal is released. If the ACC is deactivated, or the brake pedal is pressed, ACC will disengage but the set speed memory will be kept. Press the speed selector switch again and the vehicle will return to the set speed.
Setting a Distance in the ACC
Warning: ACC does not compensate for traffic, road or weather conditions. The driver is responsible for vehicle speed and braking in emergency situations. Do not use ACC in conditions that do not permit a constant speed such as heavy traffic, winding roads or slippery roads due to weather conditions.
The ACC system will maintain a set distance from the vehicle in front. If the vehicle begins to brake, your vehicle will also slow down to match, and increase speed to match up to the speed set in the cruise control. The distance between the two vehicles can be set with the distance controls (4) and (5).
The ACC system may not be able to detect narrow vehicles such as motorcycles or vehicles driving on a different line. Detection of obstacles can also be affected by dirty or obscured sensors.
Deactivating ACC or Variable Speed Limiter
Press the CAN button (3) to deactivate ACC or the variable speed limiter. The ACC and variable speed limiter set speeds will also be cleared when the ignition is set to OFF.
ACC will automatically deactivate when:
- The brake pedal is pressed.
- The park brake is applied.
- Vehicle speed drops below 20 km/h (13 mph).
- Neutral, Park or Reverse gear positions are selected.
- The traction control system is activated.
- The variable speed limiter system is activated.
- A fault occurs in the ACC system. The system will not operate until the fault is cleared.
Hill Descent Control (HDC)
Warning: Hill Descent Control is an aid only and does not replace the need for driver awareness. It is the driver’s responsibility to be aware of their surroundings. Always make sure that there is a suitable distance to the side of your vehicle for other road users and obstacles.
Warning: If there is a difference in speed between the set speed and actual speed when HDC is activated on a slippery road surface, it is possible the wheels can lose traction. This can increase the risk of the vehicle skidding and having an accident. Be aware of the road surface conditions before activating the HDC system.
Active Cruise Control and Active Brake Assist are disabled when HDC is active.
HDC is intended to be used with All-Season tires (Refer to ’All Season Tyres’, page 11.17).
Hill Descent Control (HDC) uses the ABS system to control the speed of the vehicle on downhill roads and terrain. The braking effect used by the HDC system increase as the downhill gradient becomes steeper. HDC will only operate with the transmission in D (Drive), R (Reverse), and only in GT, Terrain, and Terrain+ modes.
To Activate HDC
To activate the HDC system, press the HDC button (A).
A warning symbol will be shown with the target set speed when the system is active. If the brake pedal is pressed, this will automatically override the braking function of the HDC system. When the brake pedal is released, HDC will resume control of the braking when necessary.
Setting A Speed
Lightly push the speed selector switch (B) up to increase speed, or down to decrease speed in 1 km/h (1 mph) increments. Pressing the switch in either direction will set a new vehicle speed in the cruise control or new vehicle speed limit.
HDC will set a vehicle speed of between 2 km/h (2 mph) and 40 km/h (25 mph).
Deactivating HDC
HDC will be deactivated when the drive mode is changed to Sport, Sport+ or when the HDC button is pressed.
HDC will deactivate automatically if the vehicle speed exceeds 45 km/h (28 mph).
