waves. This may cause the maximum per-
missible water depth to be exceeded.
Failure to observe these notes may result
in damage to the engine, electrical systems
and transmission. Off-road driving
Points to remember
Off-road driving is only possible when the off-
road engineering package* ( Ypage 107) is
fitted. G
Risk of accident
Drive slowly in rough terrain with which you
are unfamiliar. This will allow you to detect
unexpected obstacles more easily and, there-
fore, to reduce the risk of an accident.
Do not make U-turns on mountain roads. Oth-
erwise, the vehicle could tip over. If a slope is
too steep for the vehicle, drive back in reverse
gear.
Do not drive at an angle up steep inclines.
Otherwise, the vehicle could tip over. If you
drive up a steep incline at an angle and the
vehicle threatens to overturn, steer into the
line of fall immediately.
Never allow the vehicle to roll backwards. The
braking effect of the engine cannot be utilised
in neutral. If you only use the service brake,
you could lose control of the vehicle. G
Risk of accident
Grains of sand, particles of dirt and other
abrasive materials can enter the brake sys-
tem. This can lead to excessive wear and
unpredictable braking efficiency.
After the brakes have been exposed to dirty
conditions, have them checked and cleaned
at a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre. Otherwise,
there is a risk that braking power may be
insufficient in the event of an emergency, or
that braking efficiency may be unpredictable. Read this section before driving your vehicle
off-road. Practise by travelling over more gen-
tle off-road terrain first.
The following driving systems are specially
adapted to off-road driving:

Risk of accident
Damage to the vehicle creates the risk of an
accident for yourself and other road users. If
in doubt, have your vehicle checked at a quali-
fied specialist workshop which has the nec-
essary specialist knowledge and tools to carry
out the work required. Mercedes-Benz rec-
ommends that you use a Mercedes-Benz
Service Centre for this purpose. H
Environmental note
Protection of the environment is of primary
importance. Treat nature with respect.
Observe all prohibiting signs.
