Refueling
Important safety notes
GWARNING
Fuel is highly flammable. Improper handling of
fuel creates arisk of fire and explosion.
Avoid fire, open flames, smoking and creating
sparks under all circumstances. Switch off the
engine and, if applicable, the auxiliary heating
before refueling.
GWARNING
Fuel is poisonous and hazardous to health.
There is arisk of injury.
You must make sure that fuel does not come into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following:
RWash away fuel from skin immediately
using soap and water.
RIf fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
RIf fuel is swallowed, seek medical assis-
tance without delay.Don ot induce vomit-
ing.
RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
Electrostatic buildupc an create sparks and
ignite fuel vapors. There is arisk of fire and
explosion.
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. Any existing electrostatic buildupi s
thereby discharged.

Drive sensibly –save fuel
In order to save fuel, observe the following tips:
XThe tires should alwaysbei nflated to the rec-
ommended tire pressure.
XRemove unnecessary loads.
XRemove roof carriers when they are not nee-
ded.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all maintenanc ework carried out as
indicated by the servicei ntervals in the Main-
tenance Booklet or by the servicei nterval dis-
play.
Fuel consumption also increases when driving in cold weather, in stop-start traffic and in moun-
tainous terrain.
Overrun cutoff
If you are in overrun mode and take your foot off
the accelerator pedal, the fuel supply is cut off
when the engine speed is out of the idle speed
control range.
Drinking and driving
GWARNING
Drinking and driving and/or takin gdrugs and
driving are very dangerous combinations.
Even asmall amount of alcohol or drugs can
affect your reflexes ,perceptions and judg-
ment.
The possibility of aserious or even fatal acci-
dent is 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.
Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is ar isk of fatal injury. Thereforen ever leave
the engine running in enclosed spaces with-
out sufficien tventilation.
Certain engine systems are designed to keep
the level of poisonous substances in exhaust
fumes within legal limits.
These systems only work optimally if they are
maintained exactly in accordance with the man-
ufacturer's specifications. An ywork on the
engine should therefore be carried out by quali-
fied and authorized Mercedes-Benz technicians.
The engine settings must not be changed under
any circumstances. In addition, all specific
maintenanc ework must be carried out at regu-
lar intervals and in accordance with the service
requirement softhe dealer listed here on the
inside title page. Details can be found in the
Maintenance Booklet.
Speed limiter
GWARNING
Exceeding the stated tire load-bearing capa-
city and the approved maximum speed could
lead to tire damage or the tire bursting. There is ar isk of accident.
Therefore, only use tire types and sizes
approved for your vehicle model. Observe the
tire load ratin gand speed ratin grequired for
your vehicle.
As the driver, you must be aware of the maxi-
mum design speed of the vehicle and the maxi- mum permissible speed based on the tires (tire
and tire pressure). In particular, also observe the tire approval regulations for each country.
You must, under no circumstances, exceed the
speed limit for the tires specified by the speed
index. The speed ratin gisstated in the tire
tables (
Ypage 291).
You can permanently limit the maximum speed
of your vehicle, e.g. for driving on winter tires.
Driving tips135
Driving and parking
Z
!Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to aheavy
load, do not stop the vehicle immediately.D rive
on for ashort while.T he brakes are cooled down
more quickly in the airflow.
Wet road surfaces
If you have been driving for along time in heavy
rain without braking, there may be adelayed
response when you first apply the brakes. This
may also occur after driving through acar wash
or deep water.
You must depress the brake pedal more firmly.
Maintain alonger distance to the vehicle in
front.
While paying attention to the traffic conditions,
you should brake the vehicle firmly after driving
on aw et road surface or through acar wash. This
heats the brake discs, so that they dry more
quickly, which protects them against corrosion.
Limited braking performance on salt-
treated roads
When driving on salted roads, salt may start to
buildupont he brake disks and brake pads. This
can increase braking distances considerably.
Maintain agreater distance to the vehicle in
front.
To remove any build-up of salt that may have
formed:
XApply the brakes at the start of the journey,
occasionally during journey and at the end of
the journey. Make sure that you do not endan-
ger other road users when doing so.
New brake discs and brake pads/
linings
New brake pads and brake discs only reach their
optimal braking effect after about60m iles
(100 kilometers). Until then, compensate for
this by applying greater force to the brake pedal. For safety reasons, Mercedes-Benz recom-
mends only installing the following brake discs
and brake pads/linings:
Rbrake discs that have been approved by
Mercedes-Benz
Rbrake pads/linings that have been approved
by Mercedes-Benz or are of an equivalent
standard of quality
Other brake discs or brake pads/linings can
compromise the safety of your vehicle.
Alwaysr eplace all brake discs or brake pads/
linings on an axle at the same time and only have
them replaced at aqualified specialist work-
shop. When replacing the brake discs, always
have the brake pads/linings replaced at the
same time.
Parking brake
GWARNING
If you must brake the vehicle with the parking brake, the braking distance is considerably
longer and the wheels could lock. There is an
increased danger of skidding and accidents.
Only use the parking brake to brake the vehi-
cle when the service brake is faulty. Do not
apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again.
When driving on wet roads or dirt-covered sur-
faces, road salt and/or dirt may get into the
parking brake. This causes corrosion and a
reduction of braking force.
In order to prevent this, drive with the parking
brake lightly applied from time to time. When
doing so, drive for adistance of approximately
110 yds (100 m) at amaximum speed of 12 mph
(20 km/h).
The brake lamps are not illuminated when you
brake the vehicle using the parking brake.
Driving in wet conditions
Hydroplaning
GWARNING
There is adanger of hydroplaning occurring,
even if you are driving slowly and your tires
Driving tips137
Driving and parking
Z
have sufficient tread depth, depending on the
depth of water on the road. There isarisk of
an accident.
For this reason, avoid tire ruts and brake care-
fully.
Therefore, in heavy rain or other conditions in
which hydroplaning can occur, drive as follows:
Rreduce your speed
Ravoid tire ruts
Rapply the brakes with care
Driving on flooded roads
!Do not drive through flooded areas. Check
the depth of any water before driving through
it. Drive slowly through standing water. Oth-
erwise, water may enter the vehicle interior or
the engine compartment. This can damage
the electronic components in the engine or
the automatic transmission. Water can also
be drawn in by the engine's air suction nozzles
and this can cause engine damage.
If you have to drive on stretches of road on which
water has collected, please bear in mind that:
Rthe water level of standing water should not
be above the lower edge of the front bumper
Rdo not drive faster than walking speed
Driving in winter
GWARNING
If you shift down on aslippery road surface in
an attempt to increase the engine's braking
effect,t he 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 aslippery road surface.
!Vehicles with automatic transmission may
roll only briefly in the neutral position N.Pro-
longed rolling of the wheels, e.g. when being
towed, will result in transmission damage.
Have your vehicle winterproofed at aqualified
specialist workshop at the onset of winter. Drive particularly carefully on slippery roads.
Avoid sudden acceleration, steering and braking
maneuvers. Do not use cruise control.
If the vehicle threaten stoskid or cannot be
stopped when moving at low speed:
XShift the transmission to position N.
XTry to maintain control of the vehicle 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 ashort 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. If you do not adjust
your driving style, the vehicle may start to skid.
Always adapt your driving style and drive at a
speed to suit the prevailing weather conditions.
You should pay special attention to road condi-
tions when temperatures are around freezing
point.
You can find further information under:
R"M+S tires" (Ypage 269)
R"Snow chains" (Ypage 270)
R"Driving with summer tires" (Ypage 269)
Also observe the notes under "Winter operation" (
Ypage 269).
Driving off-road
Important safety notes
GWARNING
If you drive on asteep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is a risk of an accident.
Always drive on asteep incline in the line of
fall (straight up or down) and do not turn the
vehicle.
GWARNING
When driving off-road, your body is subject to
forces from all directions, due to the uneven
surface. You could be thrown from your seat,
for instance. There is arisk of injury.
