Warnings from various driver support systems

If you find that your car operates in a way that you had not expected, this may be because one of the car's safety-related functions has been activated.

What is happening in your car?

There are a number of functions in your car that can actively help to increase safety in traffic, for both you and other road users. You have the option of viewing a list of some of the functions and what they may do – the aim of this is to ensure you are not surprised by the activation of any of the functions. If a function is activated, you can also receive information about this via a text message in the driver display.


Read the individual sections on each system in order to fully understand the functions and learn about important warnings.

Warnings with a symbol, sound, light or vibration

The safety functions in your car can warn you in different ways. By means of vibration in the steering wheel, brake pulse, visual or acoustic signals, or symbols in the driver display, for example.

Warning and auto-brake while reversing

If obstacles are detected:
  1. A warning signal and the graphic for parking assistance illuminate to indicate the position of the obstacle.
  2. 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.

Whiplash Protection System (WHIPS)

WHIPS is a function that can protect against whiplash. The system consists of energy absorbing backrests and seat cushion, as well as a specially designed head restraint in the front seats.


The functions described are supplementary aids - they cannot handle all situations in all conditions.

The driver always bears responsibility that the vehicle is driven safely and that applicable road traffic rules and regulations are followed.
