attention to the road must always be
his / her primary focus when driving. For

Tires
Tread wear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and be-
come visible at a tread depth of approxi-
mately
1⁄16 in (1.5 mm), at which point the
tire is considered worn and should be re-
placed.The tread wear indicator appears as a solid
band across the tread.
Specified tire pressures must be main-
tained. This applies particularly if the tires
are subject to extreme operating condi-
tions (e.g. high speeds, heavy loads, high
ambient temperatures).
To reduce the risk of personal injury as a re-
sult of inadvertent vehicle movement, be-
fore turning off the engine and leaving the
vehicle always:
Keep right foot firmly on brake pedal.
Firmly depress parking brake pedal.
Move the selector lever to positionP.
Slowly release brake pedal.
When parked on an incline, turn front
wheel towards the road curb.
Turn the key to starter switch position0
and remove, or press KEYLESS-GO*
start/stop button (vehicles with
KEYLESS-GO*).
Take the key or the KEYLESS-GO
* card
with you and lock vehicle when leaving.
Warning!
G
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possi-
ble damage to your vehicle has occurred,
you should turn on the hazard warning flash-
ers, carefully slow down, and drive with cau-
ti o n t o an a re a wh ic h i s a s a fe dis ta n c e f ro m
the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have it towed to the nearest
Mercedes-Benz Center or tire dealer for re-
pairs.
Warning!
G
Do not allow your tires to wear down too far.
As tread depth approaches
1⁄16 in (1.5 mm),
the adhesion properties on a wet road are
sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.

Gasoline is highly flammable and poisonous.
It burns violently and can cause serious inju-
ry. Whenever you are around gasoline, avoid
inhaling fumes and skin contact, extinguish
all smoking materials. Never allow sparks,
flame or smoking materials near gasoline!
Warning!
G
Overfilling of the fuel tank may create pres-
sure in the system which could cause a gas
discharge. This could cause the gas to spray
back out when removing the fuel pump noz-
zle, which could cause personal injury.

Vehicle care
the car-care products recommended here.
In such cases it is best to seek aid at your
authorized Mercedes-Benz Center.
The following topics deal with the cleaning
and care of your vehicle and give important
“how-to” information as well as references
to Mercedes-Benz approved car-care prod-
ucts.
Additional information can be found in the
booklet “Vehicle Care Guide“.
Power washer
When using a power washer for cleaning
the vehicle always observe the manufac-
turer’s operating instructions.Tar stains
Quickly remove tar stains before they dry
and become more difficult to remove. A tar
remover is recommended.Paintwork, painted body components
Mercedes-Benz approved Paint Care
should be applied when water drops on the
paint surface do not “bead up”, normally
every 3 to 5 months, depending on climate
and washing detergent used.
Mercedes-Benz approved Paint Cleaner
should be applied if the paint surface
shows signs of embedded dirt (i.e. loss of
gloss).
Do not apply any of these products or wax
if your vehicle is parked in the sun or if the
hood is still hot.
Use the appropriate MB-Touch-Up Stick
for quick and provisional repairs of minor
paint damage (i.e. chips from stones, vehi-
cle doors etc.).
Engine cleaning
Prior to cleaning the engine compartment
make sure to protect electrical compo-
nents and connectors from contact with
water and cleaning agents.
iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of
water, and a KEYLESS-GO* card is in
close proximity, i.e. within approx. 3 ft.
(approx. 1 m), the vehicle could be in-
advertently locked or unlocked.
!Never use a round nozzle to power
wash tires. The intense jet of water can
result in damage to the tire.
Always replace a damaged tire.
Always keep the jet of water moving
across the surface. Do not aim directly
at electrical parts, electrical connec-
tors, seals, or other rubber parts.
258OperationVehicle careCorrosion 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. Use only 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 out-
side 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, turn signal
lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo,
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.
iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of
water, and a KEYLESS-GO* card is in
close proximity, i.e. within approx. 3 ft.
(approx. 1 m), the vehicle could be in-
advertently locked or unlocked.
