Adaptive cruise control

Adaptive cruise control

Adaptive cruise control helps the driver maintain a constant speed and a set interval to potential vehicles in front of the car. The working speed range of the function is 0–150 km/h.
The adaptive cruise control has limitations. Be aware of them before using the function. See Limitations of the adaptive cruise control function.
The driver sets a speed between 30 and 150 km/h, and a preferred interval to potential vehicles in front of the car. The car then keeps the set interval to any vehicle in front lane moving at or slower than the set speed. If there is no vehicle in front, the car maintains the set speed. The adaptive cruise control can also automatically adjust or suggest a speed setting based on traffic sign information.
Adaptive cruise control includes the following sub-function:
  Stop-and-go: If the vehicle in front stops, your car also stops. If the vehicle in front starts moving again within 5 minutes, your car also starts moving and resumes adaptive cruise control.Note: If the function stops the car and a pedestrian or other object passes between the car and the vehicle in front, the driver must resume driving again by pressing the accelerator pedal.
Activate and adjust adaptive cruise control
Warning
•  Always set a safe speed and interval adapted to the weather and the surrounding conditions. If the road is slippery or visibility is low, turn off adaptive cruise control and take full control of the car. Not doing so could cause an accident leading to death or serious injury.
The adaptive cruise control can be turned on/off by shifting the right stalk on the steering wheel.
For button and stalk locations, see Steering wheel controls.
To activate adaptive cruise control:
1. 
Shift the right stalk down once.
2. 
The current speed is used as the set speed. The speed is set to 30 km/h if the car is driving below 30 km/h.
3. 
The speed setting appears in blue on the head-up display and the driver display, and the message ACC activated appears on the driver display.
When adaptive cruise control is activated and the driver accelerates, the speed value turns gray to indicate that it is being overridden by the driver. Once the driver stops accelerating, the speed setting turns solid blue again and the car reduces the speed until it matches the set speed.
Note: To prevent a collision, the adaptive cruise control system might prevent the car from accelerating even if the driver depresses the accelerator pedal, when the car is too close to a vehicle or other obstruction.
To deactivate adaptive cruise control:
1. 
Shift the right stalk a half-step up once.
2. 
The speed setting is no longer displayed on the head-up display and turns gray in the driver display, and the message ACC canceled appears on the driver display.
Adaptive cruise control can also be deactivated by tapping the brakes.
To resume adaptive cruise control:
1. 
Press the left thumbstick.
2. 
The previously set speed is used as the set speed. The speed is set to 30 km/h if the car is driving below 30 km/h.
To set the speed to the current speed limit:
1. 
Press the left thumbstick when adaptive cruise control is active.
2. 
The current speed limit is used as the set speed.
Note: Setting the speed to the current speed limit does not need speed limit adaptation to be enabled, and the set speed will not automatically update to the speed limit if it changes (unless speed limit adaptation is enabled).
Note: As the driver, you are always responsible for being aware of and following the speed limit.
To adjust the speed:
1. 
Push the thumbstick up/down to decrease/increase the speed in 5 km/h steps. Push and hold to decrease/increase the speed continuously by 1 km/h increments.
To adjust the lead interval:
1. 
Press the left/right button on the thumbstick area to decrease/increase the lead interval by one bar. Three interval settings are available, indicated by 1–5 horizontal bars.
Note: The interval settings are not a fixed distance. The distance to the vehicle in front varies depending on the set speed.
Automatic disabling of the adaptive cruise control
Conditions that might automatically disable the adaptive cruise control include:
  A door, the hood, or the tailgate is open.
  The driver's seat belt is unbuckled.
  The performance of the brake system is reduced or the brake system malfunctions.
  The parking brake is engaged.
  The brake pedal is depressed.
  A wheel loses traction.
  The driving speed exceeds the maximum working speed of the function, or the time of depressing the accelerator exceeds the maximum permitted time.
  The car is in N, R, or P.
  The electronic stability control is disabled or malfunctions.
  The area around the windshield camera and/or front-mounted sensor is covered by dust, dirt, ice, snow, or debris.
  Any of the driving modes snow, sand, or off-road has been chosen.
Limitations of the adaptive cruise control function
Conditions that might limit the adaptive cruise control function include:
  The view of the front-mounted cameras and/or the forward-facing sensor are obstructed in any way.
  The vehicle in front of the car is too close for the system to be able to react in a timely manner.
  Driving on narrow and winding roads.
  The vehicle in front of the car is standing still or moving slowly.
Adaptive cruise control can have difficulties identifying and reacting to animals, pedestrians, small or irregularly shaped vehicles or vehicles loaded with irregular shapes. The system can also fail to identify completely stationary objects.
Additionally, adaptive cruise control can be limited by the same factors that limit the system sensors in general. See Limitations of the driver assistance system sensors.
Note: The adaptive cruise control system does not provide assistance in very sharp bends.
