Braking
XIf ABS intervenes:continue to depress the
brake pedal vigorously until the braking
situation is over.
XTo make a full brake application: depress
the brake pedal with full force.
If abs intervenes when braking, you will feel
a pulsing in the brake pedal.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions, and func-
tions as a reminder to take extra care while
driving.
Forward collision warning
General information
The distance warning function can help you to
minimize the risk of a collision with a vehi-
cle ahead or reduce the effects of such an
accident. If the distance warning function
detects that there is a risk of a collision, you
will be warned visually and acoustically.
Starting the engine also switches on the dis-
tance warning function.
Important safety notes
GWARNING
The distance warning function does not
react:
Rto people or animals
Rto oncoming vehicles
Rto crossing traffic
Rwhen cornering
Thus, the distance warning function cannot
provide a warning in all critical situa-
tions. There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
GWARNING
The distance warning function cannot
always clearly identify objects and com-
plex traffic situations.
In such cases, the distance warning func-
tion may:
Rgive an unnecessary warning
Rnot 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 dis-
tance warning function.
Observe the "Important safety notes" section for driving safety systems (
Ypage 47).
In particular, the detection of obstacles can
be impaired if:
Rthere is dirt on the sensors or anything else
covering the sensors.
Rsnow or heavy rain
Rinterference by other radar sources
Rthe possibility of strong radar reflec-
tions, for example in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different
line
Rnew vehicles or after a service on the dis-
tance warning system
Please observe the information in the sec-
tion on running-in the vehicle
(
Ypage 86).
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at low speeds where there is no visible
damage to the front of the vehicle.

Parking aid
General notes
The rear parking aid uses an acoustic signal
to indicate the distance between your vehicle
and an obstacle. If you engage reverse gear
while the engine is running, the parking aid is activated automatically.
The parking aid uses three sensors 0043in the
rear bumper to monitor the area behind your
vehicle. The sensors must be free from dirt,
ice or slush. They can otherwise not function
correctly. Clean the sensors regularly, tak-
ing care not to scratch or damage them.
When reverse gear is engaged the system
measures the distance between your vehicle
and an object. If the proximity to the object
behind the vehicle is less than 4.0 ft (1.20 m)
a beeping sound is issued. As the distance to
the object decreases the frequency increa-
ses. When the object is a maximum of 1.0 ft
(30 cm) a continuous tone is issued.
Important safety notes
The parking aid feature is only intended as an
aid. It is not a replacement for your attention
to your immediate surroundings. You are
always responsible for safe maneuvering,
parking and exiting a parking space. When
maneuvering, parking or pulling out of a
parking space, make sure that there are no
persons, animals or objects in the area in
which you are maneuvering.
!When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. The park-
ing aid does not detect such objects if they
are in the immediate vicinity of the vehi-
cle. You could damage the vehicle or the
objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes of a truck
or a pneumatic drill could cause the park-
ing aid to malfunction.
The parking aid may not function correctly
on uneven terrain.
