Rotating wheels
On vehicles with the same wheel size all
around, wheels can be rotated every 3000
to 6000 miles (5 000 to 10 000 km), or
sooner if necessary, according to the de-
gree of tire wear. The same direction of tire
rotation must be retained.
Rotate the wheels before the characteris-
tic tire wear pattern becomes visible
(shoulder wear on front wheels and tread
center wear on rear wheels).
Thoroughly clean the inner side of the
wheels after each rotation. Check and en-
sure proper tire inflation pressure.Warning!
G
Rotate front and rear wheels only if they are
of the same size.

!If your ve hic le i s eq uip pe d with a ti re i n-
flation pressure monitor*, there are
electronic components built into the
wheel.
Do not use mounting tools in the area
of the valve as they could damage the
electronic components.
To prevent damage or incorrect instal-
lation, have the tires changed at an au-
thorized Mercedes-Benz Center.
Warning!
G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
96 lb-ft (130 Nm).
Use only genuine Mercedes-Benz wheel
bolts specified for your vehicle's rims.

Vehicle care
Light alloy wheels
Mercedes-Benz approved Wheel Care
should be used for regular cleaning of the
light alloy wheels.
If possible, clean wheels once a week with
Mercedes-Benz approved Wheel Care, us-
ing a soft bristle brush and a strong spray
of water.
Follow the instructions on the container.
Instrument cluster
Use a gentle dishwashing detergent or
mild detergent for delicate fabrics as a
washing solution. Wipe with a cloth moist-
ened in a lukewarm solution. Do not use
scouring agents.Steering wheel and gear selector lever
Wipe with a damp cloth and dry thoroughly
or clean with Mercedes-Benz approved
Leather Care.
Cup holder
Use a gentle dishwashing detergent or
mild detergent for delicate fabrics as a
washing solution. Wipe with a cloth moist-
ened in lukewarm solution. Do not use
scouring agents.
Hard plastic trim items
Pour Mercedes-Benz approved Interior
Care onto a soft, lint-free cloth and apply
with light pressure.
Headliner and shelf below rear window
Clean with a soft bristle brush, or use a
dry-shampoo cleaner in case of excessive
dirt.Seat belts
The webbing must not be treated with
chemical cleaning agents. Use only clear,
lukewarm water and soap. Do not dry the
webbing at temperatures above 176°F
(80°C) or in direct sunlight.
iUse only acid-free cleaning materials.
Acid could lead to corrosion.
Warning!
G
Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.

308 OperationVehicle careLeather upholstery
Using aftermarket seat covers or wearing
clothing that has the tendency to give off
coloring (e.g. when wet, etc.) may cause
the upholstery to become permanently dis-
colored. By lining the seats with a proper
intermediate cover, contact-discoloration
will be prevented.
Wipe leather upholstery with a damp cloth
and dry thoroughly or clean with
Mercedes-Benz approved Leather Care.

Brake fluid
Visit workshop!
There is insufficient brake fluid in the
reservoir.
Risk of accident! Stop the vehicle and
notify an authorized Mercedes-Benz
Center. Do not add brake fluid! This
will not solve the problem.
Warning!
G
Driving while these messages are displayed
can result in an accident. Have your brake
system checked immediately.
If there is a malfunction in the SBC brake
system, we recommend that the vehicle be
transported with all wheels off the ground
using flatbed or appropriate wheel lift / dolly
equipment.
A tow bar must be used if circumstances do
not permit the use of the recommended
towing methods and the vehicle requires
towing with all four wheels on the ground.
Towing the vehicle with all four wheels on
the ground is only permissible for distances
up to 30 miles (50 km) and at a speed not to
exceed 30 mph (50 km / h). For more infor-
mation, refer to “Towing the vehicle”
(page 381).
If the SBC brake system enters its emergen-
cy operation mode, the driver must apply
significantly greater brake pedal pressure
and depress the pedal much further than
normal to obtain braking effect. If neces-
sary, apply full pressure to the brake pedal.
Brakes may only be applied to the front
wheels. Stopping distance is increased!
Low brake fluid in the reservoir may cause
the braking system to fail!
Don’t add brake fluid before checking the
brake system. Overfilling the brake fluid res-
ervoir can result in spilling brake fluid on hot
engine parts and the brake fluid catching
fire. You can be seriously burned.iIf you find that the brake fluid in the
brake fluid reservoir has fallen to the
minimum mark or below, have the
brake system checked for brake pad
thickness and leaks.!Brake pad thickness must be visually
inspected by a qualified technician at
the intervals specified in the Service
Booklet.
