Ignition switched on warning
A warning message appears in the instrument cluster display if the driver door is opened while the
ignition is switched on. A signal tone may also be given.
The warning is a reminder that the ignition must be switched off before leaving the vehicle.
WARNING
Improper or unsupervised use of the vehicle keys can cause accidents or serious injuries.
Always take all vehicle keys with you every time you leave the vehicle. The engine can be started and
electrical equipment such as the window controls can be operated. This can cause serious injury.
Never leave children or people requiring assistance alone in the vehicle when the vehicle is locked.
They could become trapped in the vehicle in an emergency and may not be able to get themselves
to safety. For example, locked vehicles may be subjected to very high or very low temperatures
depending on the season. This can cause serious injuries and illness or fatalities, especially in the
case of small children.
Never remove the vehicle key from the ignition if the vehicle is in motion. The steering column lock
may be activated and you will no longer be able to steer the vehicle.

Adaptive Cruise Control (ACC)
Introduction
This chapter contains information on the followingsubjects:
Special driving situations
Limits of ACC
Switching ACC on and off
Setting ACC
Troubleshooting
The Adaptive Cruise Control (ACC) maintains a speed selected by the driver. If the vehicle
approaches a vehicle in front, the ACC automatically adapts the speed so that a distance you have
selected is maintained.
Speed range
ACC controls the vehicle in the speed range between 30 km/h (20 mph) and 160 km/h (100 mph)
or 210 km/h (130 mph). This speed range may differ in certain markets.
Driving with ACC
You can override the ACC at any time. Control will be interrupted when you brake. If you accelerate,
control will be interrupted for the duration of the acceleration process and will then continue again.
Control by ACC is less dynamic when towing a trailer
if the trailer's brake lights are faulty.
Does the vehicle have ACC?
The vehicle is equipped with ACC if you can make settings for ACC in the vehicle settings of the
Infotainment system Vehicle settings menu
