Thus, the distance warning function cannot

provide a warning in all critical situations.

There is a risk of an accident.
Always pay careful attention to the traffic

situation and be ready to brake.

G

WARNING

The distance warning function cannot always

clearly identify objects and complex traffic

situations.
In such cases, the distance warning function

may:

R

give an unnecessary warning

R

not give a warning

There is a risk of an accident.
Always pay careful attention to the traffic

situation and do not rely solely on the distance

warning function.

Function

X

To activate/deactivate: activate or

deactivate the distance warning function in

the on-board computer (

Y

page 281).

If the distance warning function is not

activated, the æ symbol appears in the

assistance graphics display.
The distance warning function can help you

to minimize the risk of a front-end collision

with a vehicle ahead or reduce the effects of

such a collision. If the distance warning

function detects that there is a risk of a

collision, you will be warned visually and

acoustically. The distance warning function

cannot prevent a collision without your

intervention.
Starting at a speed of around 4 mph

(7 km/h), the distance warning function

warns you if you rapidly approach a vehicle in

front. An intermittent warning tone will then

sound, and the · distance warning lamp

will light up in the instrument cluster.

X

Brake immediately in order to increase the

distance from the vehicle in front.

or

X

Take evasive action, provided it is safe to

do so.

Due to the nature of the system, particularly

complicated but non-critical driving

conditions may also cause the system to

display a warning.
With the help of the radar sensor system, the

distance warning function can detect

obstacles that are in the path of your vehicle

for an extended period of time.
From a speed of around 40 mph (70 km/h),

the distance warning function can also react

to stationary obstacles, such as stopped or

parked vehicles.
If you approach an obstacle and the distance

warning function detects a risk of a collision,

the system will initially alert you both visually

and acoustically.
In particular, the detection of obstacles can

be impaired if:

R

dirt on the sensors or anything else

covering the sensors

R

there is snow or heavy rain

R

there is interference by other radar sources

R

there are strong radar reflections, for

example in parking garages

R

a narrow vehicle traveling in front, e.g. a

motorbike

R

a vehicle traveling in front on a different line

relative to the center of your vehicle

R

new vehicles or after the COLLISION

PREVENTION ASSIST system has been

serviced
Observe the notes in the section on

breaking-in (

Y

page 166).

Following damage to the front end of the

vehicle, have the configuration and operation

of the radar sensor checked at a qualified

specialist workshop. This also applies to

collisions at low speeds where there is no

visible damage to the front of the vehicle.
