Adaptive Cruise Control (ACC)

Introduction

Does this vehicle have ACC?
The vehicle has ACC if you can adjust ACC settings in the Assistance systems menu in the Infotainment system.

Speed range
You can set a speed of between 30 km/h (20 mph) and 210 km/h (130 mph). The maximum speed that you can set may be lower, depending on the vehicle’s equipment and country.

Driving with ACC
You can override the ACC system at any time. The regulation function is cancelled when you apply the brakes. When you accelerate, the regulation function is paused while accelerating and then resumed with the speed set.

Driver intervention request
If automatic deceleration by the ACC is not sufficient or the system limits are reached, the ACC will prompt you – with a message in the instrument cluster – to also apply the brakes. The red warning light will also turn on and a warning tone will sound. Take over steering and be ready to brake.

WARNING
ACC is not a replacement for the driver’s attention and works only within the system’s limitations. ACC cannot detect all driving situations and may not react, or may react with a delay, or may react in a way that is not desired. If you are careless, there is a risk of accidents, serious injuries and death.

• Always stay attentive and do not rely solely on the system. The driver is always responsible for control of the vehicle.
• Observe the system limitations ⇒ ACC system limitations.
• Always adapt your speed and distance to vehicles driving ahead based on the visual, weather, road, and traffic conditions.
• Take over steering immediately if a driver intervention prompt appears in the instrument cluster display or the deceleration by ACC is not sufficient.
• Apply the brakes if the vehicle continues to roll unintentionally, e.g. after a driver intervention prompt.

Special driving situations

Please read the introductory information and heed the Warnings and Notice ⇒ Introduction.
The functions described below depend on the vehicle equipment and are not available in all countries.

Stop-and-go traffic
ACC can brake vehicles with automatic transmissions to a stop and hold them stationary. ACC remains active, and the instrument cluster display shows ACC is ready for a few seconds. During this time, the vehicle will automatically move again once the vehicle driving ahead starts and if no obstacle has been detected.
Extend drive-readiness or reactivate:

1. Press RES the button.

Driving off when drive-readiness has ended and the vehicle driving ahead has already started moving:

1. Press the RES button.
   Or: Briefly press the accelerator pedal.

The ACC does not stay active in the following scenarios:

• The stationary phase lasts several minutes.
• A vehicle door is opened.
• The ignition is switched off.

WARNING
If ACC is ready and appears in the instrument cluster display and the vehicle driving ahead starts to move, your vehicle will start driving automatically. The vehicle may not be able to detect obstacles in the vehicle’s path when this happens. This may cause accidents and serious injuries.

• Check the vehicle’s path every time before you start driving and brake the vehicle if necessary.

ACC system limitations

Please read the introductory information and heed the Warnings and Notice ⇒ Introduction.

Limits of the sensor system

ACC detects driving situations using the radar and ultrasonic sensors in the front of the vehicle. The radar sensor has a range of up to approx. 120 m (approx. 400 ft).

WARNING
If you use the ACC in situations outside system limitations, accidents and serious injuries may result and legal regulations may be violated.

• Be aware of the limits of the sensor system ⇒ Limits of the sensor system and stop the regulation function in specific situations.

Unrecognizable objects
ACC only detects vehicles that are moving in the same direction. The following will not be detected:

• Pedestrians
• Animals
• Stationary vehicles
• Vehicles crossing the street or oncoming vehicles Other stationary obstacles

Fig. 113 Turning and stationary vehicles.

If, for example, a vehicle detected by the ACC turns or changes lanes and there is a stationary vehicle in front of this vehicle, the ACC will not react to the stationary vehicle fig. 113.

Switching ACC on and off
Please read the introductory information and heed the Warnings and Notice ⇒ Introduction.

Switching on

1. Press the button. ACC is not yet functioning.

Starting the regulation function

1. Press the SET button while driving forward.
   ACC saves the current speed and maintains the set distance. If the current speed is outside the specified speed range, the ACC adjusts the minimum speed when driving too slowly or the maximum speed when driving too quickly.
   In addition, the anti-slip regulation (ASR) is activated and ESC Sport is deactivated.

The following indicator lights may turn on depending on the driving situation and the instrument cluster version:

ACC is regulating – no vehicle ahead detected. ACC is regulating – vehicle ahead detected.
If the ACC is not functioning, the grey indicator lights will light up or no indicator lights will light up at all.

Cancelling the regulation function

1. Press the button briefly.
   Or: Press the brake pedal.
   The relevant indicator light for the driving situation comes on and the speed and distance are saved.

If the anti-slip regulation (ASR) is deactivated, then the Adaptive Cruise Control is automatically stopped.

Resuming the regulation function

1. Press the RES button.
   ACC assumes the last set speed and the last set distance. The instrument cluster display shows the set speed, and indicator lights turn on corresponding to the driving situation.

Switching off

1. Press and hold the button.
   The set speed is deleted.

Adjusting the ACC settings
Please read the introductory information and heed the Warnings and Notice ⇒ Introduction.

Setting the distance
Fig. 116 In the instrument cluster display: set distance during control (general example).

You can set the distance at five levels from very short to very long:

1. Press the button.
2. Press the or button.
   Steering wheel version 2: Alternatively, swipe vertically over the button area from to or.
   Or: Press the button repeatedly until the preferred distance is set.
   The instrument cluster display shows the selected level fig. 116. Heed the country-specific regulations for minimum distance.

In the Assistance systems menu of the Infotainment system, you can choose whether you want the regulation to start at the distance that was set at the end of the journey or start at a preselected distance.
If ACC is not regulating, the set distance and the vehicle will not be highlighted on the instrument cluster display.

Setting the speed
You can adjust the stored speed within the specified speed range using the buttons on the multi-function steering wheel as follows:

• + 1 km/h (1 mph): Press the + button.
  Steering wheel version 2: Alternatively, swipe the button from the bottom to the top.
• – 1 km/h (1 mph): Press the – button.
  Steering wheel version 2: Alternatively, swipe the button from the top to the bottom.
• + 10 km/h (5 mph): Press and hold the button. Pressing for the first time changes to the next-largest tens digit (km/h) or
  fives digit (mph).
• -10 km/h (5 mph): Press and hold the button. Pressing for the first time changes to the next-smallest tens digit (km/h) or
  fives digit (mph).

WARNING
ACC cannot detect all driving situations correctly. If the vehicle is less than the minimum distance from the vehicle ahead and the difference in speed between the vehicle ahead and your vehicle is so great that the speed deceleration from the ACC is not sufficient, there is a risk of a rear-end collision. This may result in serious injury or even death.

• Always be ready to apply the brakes yourself.
• To override the speed and distance control, press the accelerator pedal. In this case, ACC will not brake automatically.
• Heed the country-specific regulations regarding minimum distance.
• Always set a longer distance when there is rain, snow, or poor visibility.
