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

Switching off the engine
Important safety notes
GWARNING
The automatic transmission switches to neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away.T here isarisk of an
accident.
After switching off the engine, always switch
to parking position P.Prevent the parked vehi-
cle from rolling away by applying the parking
brake.
!If the coolant temperature is very high, e.g.
after driving on hilly roads, leave the engine
running at idle speed for about two minutes
before turning it off.
This allowst he coolant temperature to return
to normal.
Vehicles with automatic transmission
XStop the vehicle.
XShift the transmission to position P.
XApply the parking brake.
XTurn key to position0in the ignition lock and

If you then open one of the front doors or
remove the key from the ignition, the auto-
matic transmission automatically shifts to P.
If you shift the automatic transmission to N
before switching off the engine, the automatic
transmission remains in Neven if afront door
is opened.
XSecure the vehicle to prevent it from rolling
away (Ypage 132).
Parking the vehicle for along period
If you leave the vehicle parked for longer than
4w eeks, the battery may be damaged by
exhaustive discharging.
XDisconnect the battery (Ypage 250).

Driving tips
General notes
Important safety notes
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect.Y ou will require considerably
more effort to steer and brake. There is arisk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If you operate mobile communication equip-
ment while driving, you will be distracted from traffic conditions. You could also lose control
of the vehicle. There is arisk of an accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements of the countryi n
which you are driving. Some jurisdictions pro-
hibit the driver from using amobile phone while
driving avehicle.
134Driving tips
Driving and parking

!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.
