The Rear Auto Brake (RAB) and Cross Traffic Alert (CTA Option/accessory) functions are only active if the car rolls backwards or if reverse gear has been selected.
If obstacles are detected:
- A warning signal and the parking assistance graphic illuminate to indicate the position of the obstacle.
- If the driver does not pay attention to the warning and a collision is unavoidable, the car is auto-braked and an explanatory text message is shown for why the car was braked.
If the accelerator pedal is depressed forcefully then the car also reverses after braking automatically.
Warning
- The functions are supplementary driver supports intended to facilitate driving and make it safer – but they cannot handle all situations in all traffic, weather and road conditions.
- The driver is advised to read all sections in the owner’s manual that relate to these functions to learn about factors such as limitations and what the driver should be aware of before using the functions.
- Driver support functions are not a substitute for the driver’s attention and judgement. The driver is always responsible for ensuring the car is driven in a safe manner, at the appropriate speed, with an appropriate distance to other vehicles, and in accordance with current traffic rules and regulations.
Note
Cross Traffic Alert is automatically deactivated if a trailer, bicycle rack or similar is connected to the car’s electrical system.
Examples of detection and limitations
Examples of areas where the function can assist the driver to detect obstacles during reversing.
The function’s sensors cannot detect moving traffic through other parked vehicles or bulky obstacles. Here are some examples of when approaching vehicles cannot therefore be detected until they are very close.
The car is parked deep inside a parking slot.
In an angled parking slot, the sensors may be completely blocked on one side.
- Blind sector
- Sector in which the function can detect
However, as your car slowly reverses, the angle it makes with the obstructing vehicle/object changes and the blind sector rapidly decreases.
Activating and deactivating warning and auto-brake when reversing
