affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-dent are greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Pedals
GWARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use
loose floormats and do not place floormats on
top of one another.
Emission control
GWARNING
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon mon-
oxide (CO), and inhaling it can cause uncon-
sciousness and possible death.
Do not run the engine in confined areas (such as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are enter-
ing the vehicle while driving, have the cause
determined and corrected immediately. If you
must drive under these conditions, drive only
with at least one window fully open at all
times.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with the
manufacturer's specifications. For this reason,
all work on the engine should only be carried out by qualified and authorized Mercedes-Benz
technicians.
The engine settings must not be changed under
any circumstances. Furthermore, all specific
service work must be carried out at regular
intervals and in accordance with the Mercedes-
Benz service requirements. Details can be found
in the Maintenance Booklet.
Braking
Important safety notes
GWARNING
If you activate the LOW off-road gear while
driving on a slippery road surface, the wheels
may lose traction:
Rif you remove your foot from the accelera-
tor pedal when driving
Rif off road ABS intervenes when braking
If the wheels lose traction. the vehicle can no
longer be steered. There is an increased dan- ger of skidding and accidents.
Never activate the LOW off-road gear while
driving on a slippery road surface.
Downhill gradients
!On long and steep gradients, you must
reduce the load on the brakes by shifting early
to a lower gear. This allows you to take
advantage of the engine braking effect and
helps avoid overheating and excessive wear
of the brakes.
When you take advantage of the engine brak-
ing effect, a drive wheel may not turn for some
time, e.g. on a slippery road surface. This
could cause damage to the drive train. This
type of damage is not covered by the
Mercedes-Benz warranty.
Heavy and light loads
GWARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Driving tips133
Driving and parking
Z

Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
!Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a short while. This allows the airflow
to cool the brakes more quickly.
Wet roads
If driving in heavy rain for a prolonged period of time without braking, there may be a delayed
reaction from the brakes when braking for the
first time. This may also occur after the vehicle
has been washed.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the vehicle washed, brake firmly while paying attention to
the traffic conditions. This will warm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.
Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt resi-
due may form on the brake discs and brake
pads. This can result in a significantly longer
braking distance.
RBrake occasionally to remove any possible
salt residue. Make sure that you do not
endanger other road users when doing so.
RCarefully depress the brake pedal and the
beginning and end of a journey.
RMaintain a greater distance to the vehicle
ahead.
Servicing the brakes
!If the brake warning lamp lights up in the
instrument cluster and you hear a warning
tone even though the parking brake has been released, the brake fluid level may be too low.
Observe additional warning messages in the
multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines. Have the brake system checked immediately.
This work should be carried out at a qualified
specialist workshop.
!A function or performance test should only
be carried out on a 2-axle dynamometer. If
you are planning to have the vehicle tested on
such a dynamometer, contact an authorized
Mercedes-Benz Center to obtain further infor-
mation first. Otherwise, you could damage
the drive train or the brake system.
!As the ESP®system operates automatically,
the engine and the ignition must be switched
off (the SmartKey must be in position 0or 1in
the ignition lock) if the parking brake is tested
on a brake dynamometer (for a maximum of
ten seconds).
Braking applications triggered automatically
by ESP
®may otherwise seriously damage the
brake system.
Mercedes-Benz recommends that you only have
brake pads/linings installed on your vehicle
which have been approved for Mercedes-Benz
vehicles or which correspond to an equivalent
quality standard. Brake pads/linings which have
not been approved for Mercedes-Benz vehicles
or which are not of an equivalent quality could
affect your vehicle's operating safety.
Mercedes-Benz recommends that you only use
brake fluid that has been specially approved for
your vehicle by Mercedes-Benz, or which corre-
sponds to an equivalent quality standard. Brake
fluid which has not been approved for
Mercedes-Benz vehicles or which is not of an
equivalent quality could affect your vehicle's
operating safety.
All checks and maintenance work on the brake
system must be carried out at a qualified spe-
cialist workshop.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop.
If your brake system is subject only to moderate
loads, you should test the functionality of your
brakes at regul ar interva
ls by pressing firmly on
the brake pedal at high speeds. This improves
the grip of the brake pads.
You can find a description of Brake Assist (BAS)
on (
Ypage 56).

wave could cause water to enter and damage
the engine and other 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 equipment.
iYou may only drive through fresh water.
RObserve the safety notes (Ypage 137) and
the general notes (Ypage 137) on off-road
driving.
REstablish how deep the water is and the char-
acteristics of the body of water before ford-
ing.
RSwitch off the air-conditioning system.
RShift the transfer case to LOW RANGE
(Ypage 162).
REngage the differential locks, if necessary
(Ypage 165).
RRestrict the shift range to 1or 2
(Ypage 123).
RAvoid high engine speeds.
REnter and exit the water at a flat place and at
a steady walking pace.
RDrive slowly and at an even speed through the
water.
RDo not stop and do not switch off the engine.
RWater offers a high degree of resistance, and
the ground is slippery and in some cases
unstable. Therefore, it is difficult and danger-
ous to pull away in the water.
REnsure that a bow wave does not form as you
drive.
RClean any mud from the tire tread after ford-
ing.
RApply the brakes to dry them after fording.
Always observe the fording depth values
(
Ypage 296).
Winter driving
General notes
GDANGER
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 heatingrunning, 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.
GWARNING
If you have installed unsuitable snow chains to the front wheels, they may drag against the
vehicle body or chassis components. This
could cause damage to the vehicle or the
tires. There is a risk of an accident.
Only equip the front wheels with suitable
snow chains that guarantee sufficient dis-
tance to the vehicle body and to the suspen-
sion components in every driving situation.
Always follow the manufacturer's installation
instructions when installing the snow chains.
Have your vehicle winter-proofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Winter operation" sec- tion (
Ypage 264).
Driving with summer tires
Observe the notes in the "Winter operation" sec-tion (Ypage 264).
Slippery road surfaces
GWARNING
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.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.

driving on a slippery road surface, the wheels
may lose traction:
Rif you remove your foot from the accelera-
tor pedal when driving
Rif off road ABS intervenes when braking
If the wheels lose traction. the vehicle can no
longer be steered. There is an increased dan- ger of skidding and accidents.
Never activate the LOW off-road gear while
driving on a slippery road surface.
Drive particularly carefully on slippery road sur-
faces. Avoid sudden acceleration, steering and
braking maneuvers. Do not use cruise control.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift the transmission to position N.
XTry to bring the vehicle under control 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 freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in
wooded areas or on bridges. You should pay
special attention to road conditions when tem-
peratures are around the freezing point.
For more information on driving with snow
chains, see (
Ypage 264).
Off-road driving
Important safety notes
GWARNING
Do not load items on the basic carrier bars. It
may cause instability during some maneuvers
which could result in an accident.
Drive slowly in unknown terrain. This will
make it easier to recognize unexpected obsta-
cles and avoid damage to the vehicle.
To help avoid the vehicle rolling over, never
turn it around on steep inclines. If the vehicle cannot complete the attempted climb, back it
down in reverse gear.
Do not drive along the side of a slope. The
vehicle might otherwise rollover. If in doing so
the vehicle begins to show a tendency to roll,immediately steer into a line of gravity
(straight up or downhill).
Never let the vehicle roll backwards in idle.
You may lose control of the vehicle if you use
only the service brake. For information on
driving downhill, see "Driving downhill".
When driving off-road, sand, mud and water,
possibly mixed with oil, for example, could get
into the brakes. This could result in a reduced
braking effect or in total brake failure and also in
increased wear and tear. The braking charac-
teristics change depending on the material
ingressing the brakes. Clean the brakes after
driving off-road. If you detect a reduced braking
effect or grinding noises, have the brake system checked in a qualified specialist workshop as
soon as possible. Adapt your driving style to the
different braking characteristics.
Driving off-road increases the likelihood of dam-
age to the vehicle, which, in turn, can lead to
failure of the mechanical assembly or systems.
Adapt your driving style to suit the terrain con-
ditions. Drive carefully. Have damage to the
vehicle rectified immediately at a qualified spe-
cialist workshop.
General notes
HEnvironmental note
Protection of the environment is of primary
importance. Treat nature with respect.
Observe all prohibiting signs.
Read this section carefully before driving your
vehicle off-road. Practice by driving over more
gentle off-road terrain first.
Familiarize yourself with the characteristics of
your vehicle and the gear shift operation before driving through difficult terrain.
