Driver assistance systems
●
Do not
driv
e f
aster than a pedestrian.
●
Do not stop in the water, use reverse gear
or switch off the engine.
●
Oncoming traffic will cause waves which
raise the level of the water, making it difficult
to cross the water.
The Start/Stop system must be deactivated
when driving through flooded areas
WARNING
When driving through water, mud, melted
snow
, etc., please remember that due to
damp or frozen brake discs and shoes in win-
ter, the braking effect may be delayed, there-
fore the required braking distance is greater.
●
“Dry the brakes and remove ice” by braking
carefully. Ensure that you are not endanger-
ing other road-users or breaking traffic regu-
lations in the process.
●
After driving through water, avoid sudden
sharp manoeuvres.
CAUTION
●
Driving thr
ough flooded areas may severely
damage vehicle components such as the en-
gine, transmission, drive train or electrical
system.
●
Never drive through salt water as salt cau-
ses corrosion. Always rinse any parts of the
vehicle which have been in contact with salt
water.

Brake assist systems
The brake assist systems ESC, ABS, BAS, ASR
and EDL only
operate when the ignition is
switched on. They contribute significantly to
increasing active safety.
Electronic Stability Control (ESC)
ESC reduces the risk of skidding and increa-
ses the vehicle stability by braking individual
wheels under specific driving conditions. ESC
detects critical handling situations, such as
understeer, oversteer and wheelspin on the
driven wheels. The system stabilises the ve-
hicle by braking individual wheels or by re-
ducing the engine torque.
The ESC has limits. It is important to realise
that the ESC is also subject to the laws of
physics. ESC will not be able to deal with all
situations with which drivers may be faced.
For example, if the road surface changes sud-
denly then ESC will not be useful in all cases.
If the vehicle suddenly enters a section cov-
ered by water, mud or snow then ESC will not
provide assistance in the same way as on dry
ground. If the vehicle loses its grip on the
ground and moves on a film of water (“aqua-
planing”), the ESC will not be able to assist
the driver to control the vehicle as the loss of
adherenc
e with the road surface will prevent-
ing braking and steering. If the vehicle is
driven through series of bends at high
speed, the ESC will not always be as effec-
tive: the vehicle reaction to aggressive driv-
ing is not the same as at reduced speeds.
When driving with a trailer, ESC does not pro-
vide the same amount of vehicle control as
without a trailer.
Adjust your speed and driving style to road,
traffic and weather conditions. ESC cannot
push the limits of the laws of physics; im-
prove the transmission available or maintain
the vehicle on the road if a lack of driver at-
tention creates an inevitable situation. Other-
wise, ESC assists in maintaining vehicle con-
trol in extreme situations and uses the move-
ments of the steering made by the driver to
maintain the vehicle moving in the desired
direction. If the vehicle is driven at such a
speed that it will leave the road before ESC
can intervene then the system cannot pro-
vide assistance.
The ABS, BAS, ASR and EDL systems are in-
corporated into the ESC. The ESC is always
on. The ESC should only be turned off using
the ASR button

Fig. 204 when traction is
insufficient. Always remember to turn on the
ASR once more when the vehicle has traction
again.
