improve driving safety
The vehicle begins adjusting to the set
vehicle level as soon as the doors or tail-
gate are


unlocked
or


opened or closed with the vehicle
unlocked
For major changes in vehicle level, the
engine must be running.
iThe setting is stored when you turn off
the engine.
iChanges to the vehicle level should be
made while the vehicle is moving. The
vehicle will then reach the set level as
fast as possible.
Warning!
G
Make sure that 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.Warning!
G
Adapt your speed and driving to possible
changed driving behavior of the vehicle after
changing the vehicle level. The ESP
® cannot
prevent accidents, including those resulting
from excessive speed. The ESP
® cannot pre-
vent the natural laws of physics from acting
on the vehicle.

Driving systems
Range of the sensors
To function properly, the sensors must be
free of dirt, ice, snow and slush. Clean the
sensors regularly, being careful not to
scratch or damaging the sensors, see
“Cleaning the Parktronic* system sensors”
(page 399).

!During parking maneuvers, pay special
attention to objects located above or
below the height of the sensors
(e.g. planters or trailer hitches).
The Parktronic system will not detect
such objects at close range and dam-
age to your vehicle or the object may
result.
Ultrasonic signals from outside
sources (e.g. working jackhammers,
car wash or the air brakes of trucks)
may impair the operation of the
Parktronic system.

Cup holders
Cup holders in front center console
A cupholder and a card/ticket holder with
bottle opener are located in the front cen-
ter console.
1Cup holdersWarning!
G
In order to help prevent spilling liquids on
vehicle occupants and/or vehicle equip-
ment, only use containers that fit into the
cup holder. Use lids on open containers and
do not fill containers to a height where the
contents, especially hot liquids, could spill
during braking, vehicle maneuvers, or an
accident. Liquids spilled on vehicle occu-
pants may cause serious personal injury.
Liquids spilled on vehicle equipment may
cause damage not covered by the
Mercedes-Benz Limited Warranty.
When not in use, keep cup holders closed.
An open cup holder may cause injury to you
or others when contacted during braking,
vehicle maneuvers, or in an accident.
Keep in mind that objects placed in a cup
holder may come loose during braking,
vehicle maneuvers, or an accident and be
thrown around in the vehicle interior.
Objects thrown around in the vehicle interi-
or may cause an accident and/or serious
personal injury.

Hood
Opening
1Hood lock release lever

Pull release lever1 downwards.
The hood is unlocked. Handle2 pro-
trudes slightly from the radiator grille.
If not, lift the hood slightly.
2Handle for opening the hood

Press and hold handle2 in direction
of arrow.
The hood is unlocked.

Pull up on the hood and then release it.
The hood will be automatically held
open at shoulder height by gas-filled
struts.
Warning!
G
Do not pull the release lever while the vehi-
cle is in motion. Otherwise the hood could
be forced open by passing air flow.
!To avoid damage to the windshield wip-
ers or hood, never open the hood if the
wiper arms are folded forward away
from the windshield.
Warning!
G
To help prevent personal injury, stay clear of
moving parts when the hood is open and the
engine is running. Make sure the hood is
properly closed before driving. When closing
the hood, use extreme caution not to catch
hands or fingers.
The radiator fan may continue to run for ap-
proximately 30 seconds or even restart af-
ter the engine has been turned off. Stay
clear of fan blades.


346 OperationEngine compartment
Closing
Let the hood drop from a height of
approximately 1 ft (30 cm).
The hood will lock audibly.

Check to make sure the hood is fully
closed.
If you can raise the hood at a point
above the headlamps, then it is not
properly closed. Open it again and let it
drop with somewhat greater force.
Engine oil
The amount of oil your engine needs will
depend on a number of factors, including
driving style. Increased oil consumption
can occur when

the vehicle is new


the vehicle is driven frequently at
higher engine speeds
Engine oil consumption checks should only
be made after the vehicle break-in period.
Warning!
G
If you see flames or smoke coming from the
engine compartment, or if the coolant tem-
perature gauge indicates that the engine is
overheated, do not open the hood. Move
away from vehicle and do not open the hood
until the engine has cooled. If necessary,
call the fire department.Warning!
G
The engine is equipped with a transistorized
ignition system. Because of the high voltage
it is dangerous to touch any components (ig-
nition coils, spark plug sockets, diagnostic
socket) of the ignition system

with the engine running


while starting the engine


if ignition is “on” and the engine is
turned manually
Warning!
G
Be careful that you do not close the hood on
anyone.!Do not push the hood closed manually,
as this could damage it.
iDo not use any special lubricant addi-
tives, as these may damage the drive
assemblies. Using special additives not
approved by Mercedes-Benz may
cause damage not covered by the
Mercedes-Benz Limited Warranty.
More information on this subject is
available at any Mercedes-Benz Light
Truck Center.

Tires and wheels
Aspect ratio
The aspect ratio2 (
page 376) is the
dimensional relationship between tire
section height and section width and is
expressed in percentage. The aspect ratio
is arrived at by dividing section height by
section width.
Tire code
The tire code3 (
page 376) indicates
the tire construction type. The “R” stands
for radial tire type. Letter “D” means diag-
onal or bias ply construction; letter “B”
means belted-bias ply construction.
At the tire manufacturer’s option, any tire
with a speed capability above 149 mph
(240 km/h) can include a “ZR” in the size
designation (for example: 245/40 ZR 18).
For additional information, see “Tire speed
rating” (
page 378).Rim diameter
The rim diameter4 (
page 376) is the
diameter of the bead seat, not the
diameter of the rim edge. Rim diameter is
indicated in inches (in).
Tire load rating
The tire load rating5 (page 376) is a
numerical code associated with the
maximum load a tire can support.
For example, a load rating of 91 corre-
sponds to a maximum load of 1356 lbs
(615 kg) the tire is designed to support.
See also “Maximum tire load”
(
page 382) where the maximum load as-
sociated with the load index is indicated in
kilograms and lbs.
Warning!
G
The tire load rating must always be at least
half of the GAWR (
page 386) of your vehi-
cle. Otherwise, tire failure may be the result
which may cause an accident and/or seri-
ous personal injury to you or others.
Always replace rims and tires with the same
designation, manufacturer and type as
shown on the original part.
Warning!
G
Do not overload the tires by exceeding the
specified load limit as indicated on the plac-
ard located on the driver’s door B-pillar.
Overloading the tires can overheat them,
possibly causing a blowout. Overloading the
tires can also result in handling or steering
problems, or brake failure.

This marking tells you about the type of
cord and number of plies in the sidewall
and under the tread.
Tire and loading terminology
Accessory weight
The combined weight (in excess of those
standard items which may be replaced) of
automatic transmission, power steering,
power brakes, power windows, power
seats, radio, and heater, to the extent that
these items are available as
factory-installed equipment (whether
installed or not).
Air pressure
The amount of air inside the tire pressing
outward on each square inch of the tire.
Air pressure is expressed in pounds per
square inch (psi), or kilopascal (kPa) or
bars.
Aspect ratio
Dimensional relationship between tire
section height and section width
expressed in percentage.
Warning!
G
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underin-
flation, or excessive loading, either sepa-
rately or in combination, can cause
excessive heat build-up and possible tire
failure.

data on tires are specific to each vehi-
