desired suspension tuning is reached.
The setting remains stored when you turn off
the engine. Vehicle level control
Your vehicle automatically adjusts its ride
height.
The all-around vehicle level control provides
best possible suspension and constant
ground clearance. The vehicle lowers at high
speed automatically in order to increase
driving safety and to reduce fuel
consumption.
Changes to the vehicle level should be made
while the vehicle is moving. The vehicle will
then reach the set level as fast as possible.
When you park the vehicle and the ambient
temperature changes, the vehicle level may
change visibly. When the temperature drops,
the vehicle lowers. When the temperature
rises, the vehicle raises.
The vehicle begins adjusting to the set vehicle
level as soon as the doors or tailgate are
unlocked or opened or closed with the vehicle
unlocked.
For major changes in vehicle level, the engine
must be running. G
Warning!
Make sure no one is near the wheel housing
or under the vehicle when you lower the
vehicle while it is standing still. Limbs could
become wedged into or under the vehicle.
For safety reasons, the vehicle can only be
lowered with all doors and the tailgate closed.
Lowering is interrupted if a door or the tailgate is opened and will continue after the door is
closed again.
! Keep in mind that on rough or uneven
roads, adjusting the vehicle to a lower level
may cause the vehicle underbody to come
in contact with the road and result in
damage to the vehicle underbody. Always
make sure the vehicle has sufficient ground
clearance before adjusting it to a lower
level.
! Before jacking up the vehicle with
equipment that lifts one or more of the
wheels completely off of the ground,
remove the SmartKey from the starter
switch.

(Y page 256).
i Obey local speed limits. Use prudent
driving speeds appropriate to prevailing
conditions.
Raised level Only select the raised level if appropriate for
the driving situation encountered. Otherwise
the fuel consumption may increase and/or
the handling characteristics of the vehicle
may be unfavorable.
i
You can select the raised level at speeds
up to 25 mph (40 km/h). At higher speeds,
the message Á Level Selection

bring road-salt-impaired braking efficiency
back to normal.
If the vehicle is parked after being driven on
salt-treated roads, the braking efficiency
should be tested as soon as possible after
driving is resumed.
G
Warning!
Make sure not to endanger any other road
users when carrying out these braking
maneuvers. Driving instructions
Drive sensibly – save fuel
To save fuel you should:
R Keep tires at the recommended inflation
pressures.
R Remove unnecessary loads.
R Remove carriers when not in use.
R Allow engine to warm up under low load
use.
R Avoid frequent acceleration and
deceleration.
R Have all maintenance work performed at
the intervals specified in the Maintenance
Booklet and as required by the
Maintenance system. Contact an
authorized Mercedes-Benz Center.
Fuel
consumption is also increased by driving
in cold weather, in stop-and-go traffic, on
short trips and in mountainous areas. Drinking and driving
G
Warning!
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and
judgment. The possibility of a serious or even fatal
accident

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
taking drugs. Pedals
G
Warning!
Make sure absolutely no objects are
obstructing the pedals’ range of movement.
Keep the driver’s footwell clear of all
obstacles. If there are any floormats or
carpets in the footwell, make sure that the
pedals still have sufficient clearance.
During sudden driving or braking maneuvers,
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury. Power assistance
G
Warning!
There is no power assistance for the steering
and
the brake when the engine is not running.
Steering and braking requires significantly
more effort and you could lose control of the
vehicle and cause an accident as a result.
Do not turn off the engine while the vehicle is
in motion. Brakes
Downhill grades !
When driving down long and steep
grades, relieve the load on the brakes by
shifting into a lower gear to use the
engine’s

braking power. This helps prevent
overheating of the brakes and reduces
wear. Driving instructions

Vehicles with MOExtended system are
not factory-equipped with a TIREFIT kit.
When
retrofitting with tires that do not have
run-flat characteristics, you should also
equip your vehicle with a TIREFIT kit.
TIREFIT kits are available at any authorized
Mercedes-Benz Center.
! Using tires other than those approved by
Mercedes-Benz can have detrimental
effects, such as
R poor handling characteristics
R increased noise
R increased fuel consumption
Moreover, tires and rims not approved by
Mercedes-Benz may, under load, exhibit
dimensional variations and different tire
deformation characteristics that could
cause them to come into contact with the
vehicle body or axle parts. Damage to the
tires or the vehicle may be the result.
i Further information on tires and rims is
available at any authorized Mercedes-Benz
Center. The Tire and Loading Information
placard with the recommended tire
inflation pressures for cold tires is located
on the driver’s door B-pillar. Supplemental
tire inflation pressure information for
driving at high speeds or for vehicle loads
less than the maximum loaded vehicle
condition can be found on the tire inflation
pressure label. The tire inflation pressure
label is located on the inside of the fuel filler
flap. The tire inflation pressure should be
checked regularly and should only be
adjusted on cold tires. Follow tire
manufacturer’s maintenance
recommendation included with the vehicle.
For information on recommended tire
inflation pressure and supplemental tire
inflation pressure information for special
driving situations, see ( Y page 228). i
Please keep in mind that the vehicle must
be equipped
Rwith wheels of identical dimensions on
each axle (left and right)
R with tires of identical characteristics all
around, i.e. summer tires, winter tires,
all-season tires, or MOExtended tires etc.
i The following pages also list the approved
rim and tire sizes for equipping your vehicle
with winter tires. Winter tires are not
available as standard or optional factory
equipment, but can be purchased from an
authorized Mercedes-Benz Center.
Equipping your vehicle with winter tires
approved for your vehicle model may
require the purchase of rims of the
recommended size for use with these
winter tires. This depends on vehicle model
and the standard or optional factory-
equipped wheel rim/tire configuration on
your vehicle. For more information contact
an authorized Mercedes-Benz Center. 348
