brake system warning lamp in the instrument
cluster and note any brake status messages
in the multifunction display. If you regularly
drive at high speeds, it is particularly impor-
tant to have the brake system checked and
maintained regularly.
Driving on wet roads
Aquaplaning
If water has accumulated to a certain depth
on the road surface, there is a danger of aqua-
planing occurring, even if:
you are driving at low speeds
R
the tyres have adequate tread depth
R
For this reason, do not drive in tyre ruts, and
brake carefully.
Driving on flooded roads
! Bear in mind that vehicles travelling in
front or in the opposite direction create
waves. This may cause the maximum per-
missible water depth to be exceeded.
These notes must be observed under all
circumstances. You could otherwise dam-
age the engine, the electronics or the trans-
mission.
If you have to drive on stretches of road on
which water has collected, please bear in
mind that:
the maximum permissible fording depth in
R
still water is 12 cm
you should drive no faster than walking

Winter driving

WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.

DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the
vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a
window on the side of the vehicle that is not
facing into the wind.
! Take care not to damage the sealing strip
and the moulding on the side of the rear
window when scraping ice off the rear win-
dow.
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres. Do
not use cruise control.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
Move the transmission to position N.
X
Try to bring the vehicle under control by
X
using corrective steering.
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges. The
vehicle could skid if you fail to adapt your
driving style. Always adapt your driving style
and drive at a speed to suit the prevailing
weather conditions.
