Steep roads and/or heavy load
Bear in mind that the adaptive cruise control is
primarily intended for use when driving on level
road surfaces. The function may have difficulty in
keeping the correct distance from the vehicle

which case, be extra attentive and ready to brake.
Do not use adaptive cruise control if the car

has a heavy load or a trailer is connected to
the car.
Miscellaneous
Drive mode Off Road cannot be selected

itations – see the sections "Limitations for
Camera Unit" and "Limitations for Radar Unit"
respectively.
