!
This vehicle is not designed to carry items
on its roof. Roof rails and any roof-mounted
devices, unless expressly approved by
Mercedes-Benz for use on this vehicle
model, must not be used as they will
damage the vehicle and retractable
hardtop.
At time of printing, Mercedes-Benz does
not offer any roof racks or any other roof-
mounted devices for use on this vehicle.
! This vehicle is not designed to carry any
items on its trunk lid or accommodate any
type of trunk lid rack or device. Using such
devices may damage the vehicle and
retractable hardtop mechanism. Rims and tires
Notes
! Only

use tires which have been tested and
approved by Mercedes-Benz. Tires
approved by Mercedes-Benz are developed
to provide best possible performance in
conjunction with the driving safety systems
on your vehicle such as the ABS or the
ESP ®
. Tires specially developed for your
vehicle and tested and approved by
Mercedes-Benz can be identified by finding
the following on the tire’s sidewall:
R MO = Mercedes-Benz 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.
! Using tires other than those approved by
Mercedes-Benz can have detrimental
effects, such as
R poor handling characteristics
R increased noise
R increased fuel consumption Moreover, tires and rims not approved by
Mercedes-Benz may, under load, exhibit
dimensional 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.
i Further information on tires and rims is
available

at any authorized Mercedes-Benz
Center. The Tire and Loading Information
placard with the recommended tire
inflation pressures for cold tires is located
on the driver’s door B-pillar. Supplemental
tire inflation pressure information for
driving at high speeds or for vehicle loads
less than the maximum loaded vehicle
condition can be found on the tire inflation
pressure label. The tire inflation pressure
label is 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 maintenance
recommendation included with the vehicle.
For information on recommended tire
inflation pressure and supplemental tire
inflation pressure information for special
driving situations, see ( Y page 198).
i Please keep in mind that the vehicle must
be equipped
R with wheels of identical dimensions on
each axle (left and right)
R with tires of identical characteristics all
around, i.e. summer tires, winter tires, or
all-season tires etc.
i The following pages also list the approved
rim and tire sizes for equipping your vehicle
with winter tires. Winter tires are not
available as standard or optional factory
equipment, but can be purchased from an
authorized Mercedes-Benz Center.
Equipping your vehicle with winter tires
approved for your vehicle model may
require the purchase of rims of the Rims and tires

Spare wheel
! Compare the recommended tire inflation pressure for your vehicle with the tire inflation
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 tire to the recommended tire inflation pressure
given on the yellow label on the spare wheel rim.
i Please note that the tire inflation pressure of the spare wheel differs from the tire inflation
pressure of the road tires.
i The SLK 55 AMG with Performance Package does not have a spare wheel. The SLK 55 AMG
with Performance Package is equipped with TIREFIT ( Y page 273). All models

Fuels, coolants, lubricants, etc.
Capacities
Vehicle components and their respective
lubricants must match. Therefore only use
products tested and approved by Mercedes-
Benz.
For information on tested and approved
products, contact an authorized Mercedes-
Benz Center or visit www.mbusa.com (USA

Warning!
Comply with all valid regulations with respect
to handling, storing, and disposing of service fluids. Otherwise you could endanger persons
or the environment.
Keep service fluids out of the reach of
children.
For health reasons, you should prevent
service

fluids from coming into direct contact
with your skin or clothing.
If a service fluid is swallowed, contact a
physician immediately.

of these oxygenates to gasoline does not
exceed 10%; MTBE must not exceed 15%.
The ratio of methanol to gasoline must not
exceed 3% plus additional cosolvents.
Using
mixtures of ethanol and methanol is not
allowed. Gasohol, which contains 10%
ethanol and 90% unleaded gasoline, can be
used.
These blends must also meet all other fuel
requirements, such as resistance to spark
knock, boiling range, vapor pressure, etc. Gasoline additives
A major concern among engine
manufacturers is carbon build-up caused by
gasoline. Mercedes-Benz recommends only
the use of quality gasoline containing
additives that prevent the build-up of carbon
deposits.
After an extended period of using fuels
without such additives carbon deposits can
build up, especially on the intake valves and
in the combustion area, leading to engine
performance problems such as:
R Warm-up hesitation
R Unstable idle
R Knocking/pinging
R Misfire
R Power loss
In areas where carbon deposits may be
encountered due to lack of availability of
gasoline which contains these additives, the
use of Mercedes-Benz approved additives is
recommended.
Contact

an authorized Mercedes-Benz Center
or visit www.mbusa.com (USA only) for a
listing of approved products. Follow
directions on the product label.
Do not blend other fuel additives with fuel.
This only results in unnecessary cost and may
be harmful to the engine operation. !
Damage or malfunction resulting from
poor

fuel quality or from blending additional
fuel additives other than those tested and
approved by us for use on Mercedes-Benz
vehicles are not covered by the Mercedes-
Benz Limited Warranty or by any pre-owned
or Extended Limited Warranties. Coolants
The engine coolant is a mixture of water and
anticorrosion/antifreeze, which provides:
R Corrosion protection
R Freeze protection
R Boiling

protection (by increasing the boiling
point)
The cooling system was filled at the factory
with a coolant providing freeze protection to
approximately -35‡ (-37†) and corrosion
protection.
! Add premixed coolant solution only.
Adding water and MB 325.0 Anticorrosion/
Antifreeze separately from each other,
could cause engine damage not covered by
the Mercedes-Benz Limited Warranty.
If the antifreeze mixture is effective to -35‡
(-37†), the boiling point of the coolant in the
pressurized cooling system is reached at
approximately 266‡ (130†).
The coolant solution must be used year round
to provide the necessary corrosion protection
and increase boil-over protection. Refer to
the Maintenance Booklet for replacement
interval.
Coolant system design and coolant used
determine the replacement interval. The
replacement interval published in the
Maintenance Booklet is only applicable if
MB 325.0 Anticorrosion/Antifreeze solution
or other Mercedes-Benz approved products
of equal specification are used to renew the
coolant concentration or bring it back up to
the proper level. 304
