Vehicle care
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
discolored. By lining the seats with a
proper intermediate cover,
contact-discoloration will be prevented.Leather upholstery
Please note that leather upholstery is a
natural product and is therefore subject to
a natural aging process. Leather
upholstery may also react to certain
ambient influences such as high humidity
or high temperature by showing wrinkles
for example.
Wipe leather upholstery with a damp
cloth and dry thoroughly or clean with
Mercedes-Benz approved Leather
Care.
Exercise particular care when cleaning
perforated leather as its underside should
not become wet.Wood trims
Dampen cloth using water and use
damp cloth to clean wood trims in your
vehicle.
Warning!G
Only use seat or head restraint covers which
have been tested and approved by
Mercedes-Benz for your vehicle model.
Using other seat or head restraint covers
may interfere with or prevent

deployment of the head-thorax air bags
(CLK cabriolet)

activation of the active head restraints
Contact an authorized Mercedes-Benz
Center for availability.
!Wipe with light pressure to avoid damage to
the upholstery.
!Do not use solvents like tar remover or
wheel cleaner nor polishes or waxes as these
may be abrasive.

482 Technical data
Rims and tires
!Only use tires which have been tested and
approved for your vehicle by Mercedes-Benz.
Tires approved by Mercedes-Benz are developed
to provide best possible performance in conjunc-
tion with the driving safety systems on your vehi-
cle such as ABS or ESP
®. Tires specially
developed for your vehicle and tested and ap-
proved by Mercedes-Benz can be identified by
finding the following on the tire’s sidewall:

MO = Mercedes-Benz Original equipment
tires
AMG vehicles:
Does not apply to all approved tires on AMG
vehicles. For information on tested and ap-
proved tires for AMG vehicles, contact an au-
thorized Mercedes-Benz Center.

MOE = Mercedes-Benz Original Extended
(tires with limited run-flat characteristics)
original equipment tires
Using tires other than those approved by
Mercedes-Benz may result in damage that is
not covered by the Mercedes-Benz Limited
Warranty.
iFor information on driving with MOExtended
tires, see “MOExtended system*” (
page 348).
!Using tires other than those approved by
Mercedes-Benz can have detrimental effects,
such as

poor handling characteristics

increased noise

increased fuel consumption
Moreover, tires and rims not approved by
Mercedes-Benz may, under load, exhibit dimen-
sional variations and different tire deformation
characteristics that could cause them to come
into contact with the vehicle body or axle parts.
Damage to the tires or the vehicle may be the
result.
iFurther information on tires and rims is
available at any authorized Mercedes-Benz Cen-
ter. A placard with the recommended tire infla-
tion pressures is located on the driver’s door
B-pillar. Some vehicles may have supplemental
tire inflation pressure information for driving at
high speeds (
page 340) or for vehicle loads
less than the maximum loaded vehicle condition
(
page 339).If such information is provided, it can be found
on the placard located on the inside of the fuel
filler flap. The tire inflation pressure should be
checked regularly and should only be adjusted
on cold tires. Follow tire manufacturer’s mainte-
nance recommendation included with vehicle.
iThe following pages also list the approved
wheel rim and tire sizes for equipping your vehi-
cles with winter tires. Winter tires are not avail-
able as standard or optional factory equipment,
but can be purchased from an authorized
Mercedes-Benz Center.
Depending on vehicle model and the standard or
optional factory-equipped wheel rim/tire config-
uration on your vehicle (Appearance Package,
Sport Package etc.), equipping your vehicle with
winter tires approved for your vehicle model may
also require the purchase of two or four wheel
rims of the recommended size for use with these
winter tires. See an authorized Mercedes-Benz
Center for more information.

!Please compare the recommended tire in-
flation pressure for your vehicle with the tire in-
flation pressure on the yellow label located on
the spare wheel rim.
If the tire inflation pressure on the yellow label
on the spare wheel rim differs from the values
given in this Operator’s Manual, inflate the spare
wheel tire to the recommended tire inflation
pressure given on the yellow label on the spare
wheel rim.
iPlease note that the tire inflation pressure of
the Minispare tire differs from the tire inflation
pressure of the road tires.
Make sure the Minispare tire is inflated to ap-
proximately 61 psi (4.2 bar).
iThe CLK 63 AMG cabriolet does not have a
spare wheel. The CLK 63 AMG cabriolet is
equipped with TIREFIT, see “Sealing tires with
TIREFIT (CLK 63 AMG only)” (
page 452).

495 Technical data
Fuels, coolants, lubricants, etc.
Anticorrosion/antifreeze
Your vehicle contains a number of alumi-
num parts. The use of aluminum compo-
nents in motor vehicle engines
necessitates that anticorrosion/antifreeze
coolant used in such engines be specifical-
ly formulated to protect the aluminum parts. Failure to use such anticorro-
sion/antifreeze coolant will result in a sig-
nificantly shortened service life.
Therefore, the following product is strongly
recommended for use in your vehicle:
MB 325.0 Anticorrosion/Antifreeze agent.Before the start of the winter season (or
once a year in hot southern regions), you
should have the anticorrosion/antifreeze
concentration checked. The coolant is also
regularly checked each time you bring your
vehicle to an authorized Mercedes-Benz
Center for service.
