tensioning retractor and airbag
If you believe that, even with the use of these
guidelines, it would be safer for your front
passenger seat occupant to have the passenger side
door mounted side airbag deactivated, then
deactivation can be accomplished upon your
written election to do so at your authorized
Mercedes-Benz Center at an additional cost. Please
contact your local authorized Mercedes-Benz
Center or call our Client Assistance Center at
1-800-FOR-MERCedes (1-800-367-6372) for details.Wa r n i n g !
• Damaged seat belts or belts that were highly
stressed in an accident must be replaced and
their anchoring points must also be checked.
Use only belts installed or supplied by an
authorized Mercedes-Benz Center.
• Airbags and ETR’s are designed to function on
a one-time-only basis. An airbag or emergency
tensioning retractor (ETR) that was activated
must be replaced.• Do not pass belts over sharp edges.• Do not make any modification that could
change the effectiveness of the belts.• No modifications of any kind may be made to
any components or wiring of the “SRS”. This
includes changing or removing any component
or part of the “SRS”, the installation of
additional trim material, badges etc. over the
steering wheel hub, passenger airbag cover, or
door trim panels, and installation of additional
electrical / electronic equipment on or near
“SRS” components and wiring. Keep area
between airbags and occupants free of objects
(e.g. packages, purses, umbrellas, etc.).

Winter driving
Have your vehicle winterized at your authorized
Mercedes-Benz Center before the onset of winter.
•Change the engine oil if the engine contains an oil
which is not approved for winter operation. For
viscosity (SAE / CCMC class) and filling quantity,
see page 266.
•Check engine coolant anticorrosion / antifreeze
concentration.•Additive for the windshield washer and headlamp
cleaning system: Add MB Concentrate “S” to a
premixed windshield washer solvent / antifreeze
which is formulated for below freezing
temperatures, see page 199.
•Test battery: Battery capacity drops with decreasing
ambient temperature. A well charged battery helps
to ensure that the engine can be started, even at low
ambient temperatures.
•Tires: We recommend M+S rated radial-ply tires on
all four wheels for the winter season. Observe
permissible maximum speed for M+S rated radial-
ply tires and the legal speed limit.
Note:
In winter operation, the maximum effectiveness of the
antilock brake system (ABS) or electronic stability
program (ESP) can only be achieved with M+S rated
radial-ply tires and / or snow chains recommended by
Mercedes-Benz. Snow chains maximize performance.
Wa r n i n g !
If the vehicle becomes stuck in snow, make sure
that snow is kept clear of the exhaust pipe and
from around the vehicle with engine running.
O t h e rw i s e , d e a d ly c a r b o n m on ox i d e ( CO ) ga s e s m ay

and death.To assure sufficient fresh air ventilation, open a
window slightly on the side of the vehicle not
facing the wind.

Notes:
If the engine does not brake the vehicle sufficiently
while driving on a downgrade, the speed you set on the
cruise control may be exceeded. In this case the
following will assist in maintaining the set cruise
controlled speed:
Vehicles with automatic transmission:
Downshift occurs (max. to 3rd gear) to maintain the set
cruise controlled speed by using the engine’s braking
power.
As soon as the grade eases, the automatic transmission
shifts up again dependent on the selector lever position.
Vehicles with manual transmission:
The set cruise controlled speed is switched off when
declutching exceeds four seconds during downshifting a
gear.
Nevertheless, in some cases you may have to step on the
brake pedal to slow down. In this case the cruise control
is switched off.
Use the lever to resume the previously set speed.
Wa r n i n g !
Only use the cruise control if the traffic and
weather conditions make it advisable to travel at a
steady speed.
• The use of cruise control can be dangerous on
winding roads or in heavy traffic because
conditions do not allow safe driving at a steady
speed.• The use of cruise control can be dangerous on
slippery roads. Rapid changes in tire adhesion
can result in wheel spin and loss of control.The “Resume” function should only be operated if
the driver is fully aware of the previously set speed
and wishes to resume this particular preset speed.

The jack is designed exclusively for jacking up the
vehicle at the jack tubes built into either side of the
vehicle. To help avoid personal injury, use the jack
only to lift the vehicle during a wheel change.
Never get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from the area
under the lifted vehicle. Always firmly set parking
brake and block wheels before raising vehicle with
jack.Do not disengage parking brake while the vehicle is
raised. Be certain that the jack is always vertical
when in use, especially on hills. Always try to use
the jack on level surface. Be sure that the jack arm
is fully inserted in the jack tube. Always lower the
vehicle onto sufficient capacity jackstands before
working under the vehicle.

from the roadway.
1. Set parking brake and turn on hazard warning
flasher.
2. Move selector lever to position “P” and turn off
engine (manual transmission to 1st or reverse gear).
3. Prevent vehicle from rolling away by blocking
wheels with wheel chocks (not supplied with
vehicle) or sizable wood block or stone. When
changing a wheel on a hill, place chocks on the
downhill side blocking both wheels of the other
axle. On a level road, place one chock in front of and
one behind the wheel that is diagonally opposite to
the wheel being changed.

TIREFIT
(SLK 32 AMG only)
Small punctures, particularly those in the tread can be
sealed with TIREFIT.
Foreign objects (e.g. screws or nails) should not be
removed from the tire.
TIREFIT can be used in ambient temperatures down to
approx. - 4°F (- 20°C).
Wa r n i n g !
Cuts or punctures larger than approx. 0.16 in
(4 mm), tire damage caused by driving with
extremely low tire pressure or on a flat tire, or a
damaged wheel can pose a hazard while driving.
TIREFIT should not be used in such circumstances.Do not drive the vehicle under such circumstances.Contact your nearest Mercedes-Benz Center for
assistance.Take care not to allow the contents of TIREFIT to
come in contact with hair, eyes or clothing.
TIREFIT is harmful if inhaled, swallowed or
absorbed through the skin - causes skin, eye and
respiratory irritation.
Any contact with eyes or skin should be flushed
immediately with plenty of water.If clothing comes in contact with TIREFIT, change
clothing as soon as possible.In case of allergic reaction or rash, consult a
physician immediately.Keep TIREFIT out of reach of children.
If swallowed, rinse mouth immediately with plenty
of water and drink plenty of water.Do not induce vomiting!Consult a physician immediately.Keep away from open flame or heat source.

Note:
Do not operate electric air pump longer that 6 minutes
without interruption. Air pump could overheat! After air
pump has cooled off, operate air pump again.
16. To switch off air pump, turn key in steering lock to
position 0.
17. Reinstall valve tire cap.
18. Drive vehicle to distribute the sealant evenly inside
the tire.Notes:
If TIREFIT is liquid, clean water and a damp cloth will
remove the material from the vehicle or tire and wheel
components. Once TIREFIT sealing material had dried,
it can easily be peeled off and properly discarded.
Replace TIREFIT every 4 years.
Wa r n i n g !
If a tire pressure of 26 psi (1.8 bar) is not attained,
tire is too severely damaged for TIREFIT to provide
a reliable tire repair.In this case TIREFIT can not properly seal the tire.Do not drive the vehicle.Contact the nearest Mercedes-Benz Center or call
Roadside Assistance.
Wa r n i n g !
Do not exceed vehicle speed of 50 mph (80 km / h).
A TIREFIT repair is not designed to operate at
higher speeds.Vehicle handling characteristics may change.After driving vehicle for an initial 10 minutes,
check tire pressure. If tire pressure has fallen
below 20 psi (1.3 bar) do not continue to drive the
vehicle.If tire pressure is at least 20 psi (1.3 bar), inflate
tire to correct pressure (see label on fuel filler
flap), and drive vehicle to nearest tire repair
facility to have tire repaired or replaced.Recommended duration of use: 300 miles (500 km)
at 50 mph (80 km / h) with the recommended tire
pressure.

219 Tires, wheels
Te ch n i c a l
data Instruments
and controlsOperation DrivingInstrument
cluster displayPractical hintsCar care Index Tire inflation pressure
A table (see fuel filler flap) lists the tire inflation
pressures specified for Mercedes-Benz recommended
tires as well as for the varying operating conditions.
Important!
Tire pressure changes by approximately 1.5 psi (0.1 bar)
per 18°F (10°C) of air temperature change. Keep this in
mind when checking tire pressure inside a garage -
especially in the winter.
Example:
If garage temperature = approximately +68°F (+20°C)
and ambient temperature = approximately +32°F (0°C)
then the adjusted air pressure = specified air pressure
+3psi (+0.2 bar).Tire pressures listed for light loads are minimum values
offering high driving comfort. Increased inflation
pressures for heavy loads produce favorable handling
characteristics with lighter loads and are perfectly
permissible. The ride of the vehicle, however, will
become somewhat harder.
Tire temperature and pressure increase with the vehicle
speed. Tire pressure should therefore only be checked
and corrected on cold tires. Correct tire pressure in
warm tires only if pressure has dropped below the
pressure listed in the table and the respective operating
conditions are taken into consideration.
An underinflated tire due to a slow leak (e.g. due to a
nail in the tire) may cause damage such as tread
separation, bulging etc.. Regular tire pressure checks at
intervals of no more than 14 days are therefore
essential.
