Applies to: vehicles with rear cross-traffic assist
- Fig. 148 Example diagram
- Fig. 149 Infotainment: Rear cross-traffic assist display
While you are reversing, the rear cross-traffic assist can warn against a potential collision with traffic approaching perpendicular to the rear of the vehicle. The system uses the radar sensors Fig. ► to monitor the area behind and to the side of the vehicle when you are leaving a parking space. Where possible, it detects objects, such as cars, as they approach the vehicle Fig. 148►.
If critical cross-traffic is detected when reversing out of a parking space, the system reacts as follows:
- Graphic display: A graphic with a red arrow symbol appears on the infotainment display. The arrow indicates the direction from which the object is approaching Fig. 149►.
- Warning tone: A tone may sound continuously as an additional signal when you are reversing.
- Automatic brake jolt: A short sharp application of the brakes may also warn against a potential collision with an approaching object.
Requirements for the use of the rear cross-traffic assist:
- The parking aid must be switched on link►.
- Reverse gear must be engaged.
- The speed must not be higher than approximately 15 km/h.
WARNING
- The purpose of the rear cross-traffic assist is to assist the driver; it cannot prevent a collision on its own. The driver must always intervene personally. As the driver you are always responsible for braking in good time.
- Please note that the rear cross-traffic assist may apply the brakes unexpectedly. Always secure your luggage to prevent damage and possible injury.
- After an automatic brake jolt, no further brake jolt will occur within 20 seconds.
- If the rear cross-traffic assist gives an acoustic warning signal, the parking aid may no longer be able to warn you against obstacles it has detected.
- The radar sensor vision can be impaired, e.g. by leaves, snow, heavy road spray or dirt. Clean the area in front of the sensors Fig. ►.
WARNING
The rear cross-traffic assist has certain inherent limitations and cannot warn against an impending collision in every situation:
- It cannot give a warning if the vehicle is so far into a parking space that it is hidden by the vehicles in front and behind.
- People such as cyclists, joggers, inline skaters and pedestrians may not be detected in certain situations.
- It cannot give a warning when you are parked at an angle or parallel to the roadside.
CAUTION
Please also observe the notes ►.
Note
- The automatic brake application with increasing brake force can be cancelled by applying the brakes yourself or by pressing the accelerator firmly.
- In certain situations, a warning may be given by the rear cross-traffic assist even if there is no traffic in the critical zone, for instance when parking or manoeuvring the vehicle in reverse.
- The rear cross-traffic assist is deactivated automatically if you deactivate the ESC.
- The rear cross-traffic assist is switched on/off via the parking aid link►.
- The system is not available in towing mode.
