Transmission fluid level
The transmission fluid level does not need
to be checked. If you notice transmission
fluid loss or gear shifting malfunctions,
have an authorized Mercedes-Benz Center
check the automatic transmission.
!Only use approved engine oils. For a
listing of a approved engine oils, refer
to the Factory Approved Service Prod-
u c t s p a m p hl e t i n y o u r v e h i c l e l i t e r a t u r e
portfolio.
In addition, check the oil filler cap for
important information pertaining to the
engine oil needing to meet a specific
Mercedes-Benz specification (e.g. MB
229.5). If such information is printed
on the oil filler cap, only use an engine
oil from the list of approved engine oils
in the Factory Approved Service Prod-
ucts pamphlet that meets the specifi-
cation indicated on the oil filler cap.
Using engine oils of other specification
may cause the FSS to incorrectly deter-
mine the next service interval and will
result in engine damage not covered by
the Mercedes-Benz Limited Warranty.
!Excess oil must be siphoned or drained
off. It could cause damage to the en-
gine and catalytic converter not cov-
ered by the Mercedes-Benz Limited
Warranty.

297 Operation
Tires and wheels
Important guidelines

Only use sets of tires and rims of the
same type and make.


Tires must be of the correct size for the
rim.


Break in new tires for approximately
60 miles (100 km) at moderate
speeds.


Regularly check the tires and rims for
damage. Dented or bend rims can
cause tire pressure loss and damage
the tire beads.


If vehicle is heavily loaded, check tire
pressure and correct as required.


Do not allow your tires to wear down
too far. Adhesion properties on wet
roads are sharply reduced at tread
depths under
1/8in (3 mm).


When replacing individual tires, you
should mount new tires on the front
wheels first (on vehicles with
same-sized wheels all around).
Life of tires
The service life of a tire is dependent upon
various factors including but not limited to:

Driving style


Tire pressure


Distance driven
Direction of rotation
Unidirectional tires offer added advantag-
es, such as better hydroplaning perfor-
mance. To benefit, however, you must
make sure the tires rotate in the direction
specified.
An arrow on the sidewall indicates the in-
tended direction of tire rotation.
Warning!
G
Tires and spare tire should be replaced after
six years, regardless of the remaining tread.!Keep unmounted tires in a cool, dry
place with as little exposure to light as
possible. Protect tires from contact
with oil, grease and gasoline.

tor. To arrive at the true service dead-
line, you will need to subtract these
days from the days shown in the ser-
vice indicator.
Do not confuse the service indicator
with the engine oil level indicator :.
iIf the service indicator was inadvertent-
ly reset, have a Mercedes-Benz Center
correct it.
Only reset if the proper service has
been performed. Resetting the system
without performing proper service as
called for by the FSS will cause the FSS
to incorrectly determine the next ser-
vice interval which will result in engine
damage not covered by the
Mercedes-Benz Limited Warranty.

304 OperationVehicle care
Vehicle careCleaning and care of vehicle
While in operation, even while parked, your
vehicle is subject to varying external influ-
ences which, if gone unchecked, can at-
tack the paintwork as well as the
underbody and cause lasting damage.Such damage is caused not only by ex-
treme and varying climatic conditions, but
also by:


Air pollution


Road salt


Tar


Gravel and stone chipping
To avoid paint damage, you should imme-
diately remove:


Grease and oil


Fuel


Coolant


Brake fluid


Bird droppings


Insects


Tree resins, etc.
Frequent washing reduces and / or elimi-
nates the aggressiveness and potency of
the above adverse influences.More frequent washings are necessary to
deal with unfavorable conditions:


near the ocean


in industrial areas (smoke, exhaust
emissions)


during winter operation
You should check your vehicle from time to
time for stone chipping or other damage.
A n y d a m a g e s h o u l d b e r e p a i r e d a s s o o n a s
possible to prevent corrosion.
In doing so, do not neglect the underbody
of the vehicle. A prerequisite for a thor-
ough check is a washing of the underbody
followed by a thorough inspection. Dam-
aged areas need to be re-undercoated.
Your vehicle has been treated at the facto-
ry with a wax-base rustproofing in the body
cavities which will last for the lifetime of
the vehicle. Post-production treatment is
neither necessary nor recommended by
Mercedes-Benz because of the possibility
of incompatibility between materials used
in the production process and others ap-
plied later.
Warning!
G
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the partic-
ular container. Always open your vehicle’s
doors or windows when cleaning the inside.
Never use fluids or solvents that are not de-
signed for cleaning your vehicle.

307 Operation
Vehicle care
Dry cleaning:
Brush the dry top with a soft-bristled
brush.
Brush top always from front to rear.
Wet cleaning:

Brush the top with a soft-bristled
brush.
Wash with clear water or with a mild
detergent and an ample supply of luke-
warm water by wiping with a soft-bris-
tled brush or sponge from front to
rear.Then rinse thoroughly with clear
water.Wash the top only when heavily soiled.
If only parts of the top have been washed,
wet the entire top and allow it to air-dry be-
fore lowering it into the storage compart-
ment.
For cleaning soft top or wind screen never
use:


gasoline


thinner


tar and stain removers


glass cleaner


similar organic solvents
They will cause damage which is not cov-
ered by the Mercedes-Benz Limited War-
ranty.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 Shampoo,
with plenty of water.
To prevent scratches, never apply strong
force and only use a soft, non-scratchy
cloth when cleaning the lenses. Do not at-
tempt to wipe dirty lenses with a dry cloth
or sponge.
iWhen you run the vehicle through an
automatic car wash, never use
hot-wax.
Depending on the operation mode of
the car wash, there is the possibility of
water drops entering the vehicle’s inte-
rior. This is not an indication of a defect
or malfunction in the soft top.
iIn general, regular spraying or cleaning
with clear water is sufficient to keep
the soft top clean.

310 OperationVehicle careHard plastic trim items
Pour Mercedes-Benz approved Interior
Care onto soft lint-free cloth and apply
with light pressure.
Headliner and rear window shelf
Clean with 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. Only use clear,
lukewarm water and soap. Do not dry the
webbing at temperatures above 176°F
(80°C) or in direct sunlight.Upholstery
Using aftermarket seat covers or wearing
clothing that have 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.
Leather upholstery
Wipe leather upholstery with a damp cloth
and dry thoroughly or clean with
Mercedes-Benz approved Leather Care.
Exercise particular care when cleaning per-
forated leather as its underside should not
become wet.
Nubuck leather upholstery
(CLK 55 AMG)
The nubuck leather upholstery is treated
with a protective coating. Wipe nubuck
leather upholstery with damp microfiber
cloth to remove dust and other light stains.
Carefully dab nubuck leather upholstery
with a microfiber cloth to remove oil stains.Plastic and rubber parts
Do not use oil or wax on these parts.
Wood trims
Dampen cloth using water and use damp
cloth to clean wood trims in your vehicle.
Do not use solvents like tar remover or
wheel cleaner nor polishes or waxes as
these may be abrasive.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.
!Do not use Mercedes-Benz approved
Leather Care or any solvents to clean
nubuck leather upholstery.
Avoid hard scrubbing on nubuck leath-
er upholstery.
