Hilly Condition Usage
Select a lower gear when the system is active in situations such as prolonged downhill driving on steep grades, for example in mountainous areas. The system needs additional engine braking in these situations to reduce the load on the vehicle’s regular brake system to prevent it from overheating.
Note: An audible alarm sounds and the system shuts down if it applies brakes for an extended period of time. This allows the brakes to cool. The system functions normally again after the brakes cool.
Switching Adaptive Cruise Control Off
For vehicles without Speed Limiter, press and release the button when the system is in standby mode or switch the ignition off.
For vehicles with Speed Limiter, press and release the button when the system is in standby mode or switch the ignition off.
Note: You erase the set speed when you switch the system off.
Detection Issues
WARNING: On rare occasions, detection issues can occur due to the road infrastructures, for example bridges, tunnels and safety barriers. In these cases, the system may brake late or unexpectedly. At all times, you are responsible for controlling your vehicle, supervising the system and intervening, if required.
WARNING: If the system malfunctions, have your vehicle checked as soon as possible.
The radar sensor has a limited field of view. It may not detect vehicles at all or detect a vehicle later than expected in some situations. The lead vehicle graphic does not illuminate if the system does not detect a vehicle in front of you.
Note: Depending on your vehicle option package, the controls may look different from what you see here.
