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, eve nif:
R you are driving at low speeds
R the tyres have adequate tread depth.
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 maximu mper-
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:
R the maximum permissible fording depth in
still water is 60 cm
R you should drive no faster than walking
pace
Off-road fording !
The water depth must not exceed 60 cm.
Note that the possible fording depth is less
in flowing water.
! Under no circumstances should you
accelerate before entering the water. The
bow wave could cause water to enter and
damage the engine and neighbouring
assemblies.
! Do not open any of the vehicle's doors
while fording. Otherwise, water could get
into the vehicle interior and damage the
vehicle's electronics and interior equip-
ment. The fording depth must not exceed 60 cm
when the vehicle is loaded and ready to drive.
Loaded and ready to drive means: a full tank,
all fluids topped up and the driver is in the
vehicle.
i
You may only drive through freshwater.
R Observe the safety notes (Y page 169)and
the general notes (Y page 169) on off-road
driving.
R Establish how deep the water is and the
characteristics of the body of water before
fording.
R Switch off the air-conditioning system.
R Deactivate the auxiliary heating.
R Shift the transfer case to LOW
RANGE( Ypage 201).
R Engage the differential locks, if necessary
(Y page 204).
R Restrict the shift range to 1or
2(Y page 153).
R Avoid high engine speeds.
R Enter and exi tthe water at a flat place and
at a steady walking pace.
R Drive slowly and at a constant speed
through the water.
R Do not stop and do not switch off the
engine.
R Water offers a high degree of resistance,
the ground is slippery and, in some cases,
unstable. Therefore, it is difficult and dan-
gerous to pull away in the water.
R Ensure that a bow wave does not form as
you drive. Driving tips
