The tilt/sliding sunroof is opened and
closed electrically. The switch for the
tilt/sliding sunroof is on the overhead con-
trol panel.
1Push up to raise sunroof at rear
2Pull down to lower sunroof at rear
3Push forward to slide sunroof closed
4Push back to slide sunroof openWith the sunroof closed or tilted open, a
screen can be slid into the roof opening to
help provide shade. When sliding the sun-
roof open, the screen will also retract.
Warning!
G
When closing the tilt/sliding sunroof, make
sure that there is no danger of anyone being
harmed by the closing procedure.
The closing procedure of the tilt/sliding sun-
roof can be immediately halted by releasing
the switch or, if the switch was moved past
the resistance point and released, by mov-
ing the switch in any direction.
The tilt/sliding sunroof is made out of glass.
In the event of an accident, the glass may
shatter. This may result in an opening in the
roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening also presents a potential for injury
for occupants wearing their seat belts
properly as entire body parts or portions of
them may protrude from the passenger
compartment.

314 OperationTires and wheelsGeneral:
Depending on the design standards used,
the tire size molded into the sidewall may
have no letter or a letter preceding the tire
size designation.
No letter preceding the size designation
(as illustrated above): Passenger car tire
based on European design standards.
Letter “P” preceding the size designation:
Passenger car tire based on U.S. design
standards.
Letter “LT” preceding the size designation:
Light Truck tire based on U.S. design
standards.
Letter “T” preceding the size designation:
Temporary spare tires which are high
pressure compact spares designed for
temporary emergency use only. Tire width
The tire width1 (
page 313) indicates
the nominal tire width in mm.
Aspect ratio
The aspect ratio2 (page 313) 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 313) 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 315).Rim diameter
The rim diameter4 (
page 313) 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 313) 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 1 356 lbs
(615 kg) the tire is designed to support.
See also “Maximum tire load”
(
page 319) where the maximum load as-
sociated with the load index is indicated in
kilograms and lbs.

334 OperationVehicle careEngine cleaning
Prior to cleaning the engine compartment
make sure to protect electrical compo-
nents and connectors from the intrusion of
water and cleaning agents.
Corrosion protection, such as MB Anticor-
rosion Wax should be applied to the engine
compartment after every engine cleaning.
Before applying, all control linkage bush-
ings and joints should be lubricated. The
poly-V-belt and all pulleys should be pro-
tected from any wax.
Vehicle washing
Do not use hot water or wash your vehicle
in direct sunlight. Only use a mild car wash
detergent, such as Mercedes-Benz ap-
proved Car Shampoo.
Thoroughly spray the vehicle with a dif-
fused jet of water. Direct only a very weak
spray towards the ventilation intake. Use
plenty of water and rinse the sponge and
chamois frequently. Rinse with clear water and thoroughly dry
with a chamois. Do not allow cleaning
agents to dry on the finish.
Due to the width of the vehicle, fold in ex-
terior rear view mirrors prior to running the
vehicle through an automatic car wash to
prevent damage to the mirrors.
In the winter, thoroughly remove all traces
of road salt as soon as possible.
When washing the underbody, do not for-
get to clean the inner sides of the wheels.Ornamental moldings
For regular cleaning and care of very dirty
chrome-plated parts, use a chrome clean-
er.
Headlamps, tail lamps, side markers,
turn signal lenses

Use a mild car wash detergent, such as
Mercedes-Benz approved Car Sham-
poo, with plenty of water.
To prevent scratches, never apply strong
force and use only a soft, non-scratchy
cloth when cleaning the lenses. Do not at-
tempt to wipe dirty lenses with a dry cloth
or sponge.
iAfter running the vehicle through an au-
tomatic car wash, wipe any wax off of
the windshield (
page 336) and the
wiper blade inserts (page 335). This
will prevent smears and reduce wiping
noise which can be caused by residual
wax on the windshield.
iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of
water, and a SmartKey with
KEYLESS-GO* is in close proximity, i.e.
within approx. 3 ft. (approx. 1 m), the
vehicle could be inadvertently locked
or unlocked.

severely weaken them. In a crash they may
not be able to provide adequate protection.

BATTERY CHARGE
VISIT WORKSHOP
The battery is no longer charging.
Possible causes:

alternator malfunctioning


broken poly-V-belt
Do not forget that the brake system re-
quires electrical energy and may be oper-
ating with restricted capability.
Considerably greater brake pedal force is
required and the stopping distance is
longer.

Stop immediately and check the
poly-V-belt.
If it is broken:

Do not continue to drive. Otherwise the
engine will overheat due to an inoperative
water pump which may result in damage
to the engine. Notify an authorized
Mercedes-Benz Center.
If it is intact:

Drive immediately to the nearest autho-
rized Mercedes-Benz Center. Adjust driv-
ing to be consistent with reduced braking
responsiveness.
