The vehicle jack is stored behind the spare wheel.
See illustration for proper storage of jack.
To remove, first remove vehicle tools and spare wheel.
Then open clamp and remove vehicle jack.
Before storing the jack in the spare wheel well, the jack
arm must be lowered almost to the base of the jack.
Wa r n i n g !
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.

Wheels
Replace rims or tires with the same designation,
manufacturer and type as shown on the original part.
See your authorized Mercedes-Benz Center for further
information.
See your authorized Mercedes-Benz Center for
information on tested and recommended rims and tires
for summer and winter operation. They can also offer
advice concerning tire service and purchase.
Tire replacement
Front tires should be replaced in sets. Rims and tires
must be of the correct size and type. For dimensions,
see page 320.
We recommend that you break in new tires for
approximately 60 miles (100 km) at moderate speed.
It is imperative that the wheel mounting bolts be
fastened to a tightening torque of 80 ft.lb. (110 Nm)
whenever wheels are mounted.
For rim and tire specifications, see page 320.
Wa r n i n g !
Worn, old tires can cause accidents. If the tire tread
is badly worn, or if the tires have sustained
damage, replace them.When replacing rims, use only genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can result in
the bolts loosening and possibly an accident.

The wheels can be rotated according to the degree of
tire wear while retaining the same direction of travel.
Rotating, however, should be carried out as
recommended by the tire manufacturer, before the
characteristic tire wear pattern (shoulder wear on front
wheels and tread center wear on rear wheels) becomes
visible, as otherwise the driving properties deteriorate.
Important!
Unidirectional tires must always be mounted with arrow
on tire sidewall pointing in direction of vehicle forward
movement.Notes:
Thoroughly clean the inner side of the wheels any time
you rotate the wheels or wash the vehicle underside.
The use of retread tires is not recommended. Retread
tires may adversely affect the handling characteristics
and safety of the vehicle.
Dented or bent rims can cause tire pressure loss and
damage to the tire beads. For this reason, check rims for
damage at regular intervals. The rim flanges must be
checked for wear before a tire is mounted. Remove
burrs, if any.
Check and ensure proper tire inflation pressure after
rotating the wheels. For tire inflation pressure see
page 282.

Spare wheel
Important!
Unidirectional tires must always be mounted with arrow
on tire sidewall pointing in direction of vehicle forward
movement.
If the arrow on tire side wall does not point in direction
of vehicle forward movement when using the spare
wheel, observe the following restrictions:
•Drive to the nearest tire repair facility as soon as
possible.
For rim and tire specifications, see page 320.
Spare wheel bolts1Wheel bolt for light alloy wheel rim
2Wheel bolt for steel spare wheel rim
Note:
Wheel bolts (2) must be used when mounting steel
spare wheel rim.
Wa r n i n g !
Be sure to use the original length wheel bolts when
remounting the original light alloy wheel after it
has been repaired.

from the roadway.
1. Set parking brake and turn on hazard warning
flasher.
2. Move selector lever to position “P” and turn off
engine.
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.

4. Using the wrench, loosen but do not yet remove the
wheel bolts.5. Remove the protective cover from the jack support
tube opening by inserting the screwdriver (supplied
in the tool kit) in the opening and prying it out.
The tube openings are located directly behind the
front wheel housings and in front of the rear wheel
housings.

stop. Place jack on firm ground. Position the jack so
that it is always vertical (plumb-line) as seen from
the side (see arrow), even if the vehicle is parked on
an incline.
7. Jack up the vehicle until the wheel is clear of the
ground. Never start engine while vehicle is raised.8. Unscrew upper-most wheel bolt and install
alignment bolt (1) supplied in the tool kit. Remove
the remaining bolts. Keep bolt threads protected
from dirt and sand.
9. Remove wheel. Grip wheel from the sides. Keep
hands from beneath the wheels.

Important!
When installing steel spare wheel rim, make certain to
use the correct wheel bolts, supplied in the vehicle tool
kit, see page 276 and page 272.10. Clean contact surfaces of wheel and wheel hub.
Install wheel on wheel hub. Insert wheel bolts and
tighten them slightly.
To avoid paint damage, place wheel f lat against hub
and hold it there while installing first wheel bolt.
Unscrew the alignment bolt (1) to install the last
wheel bolt.

Wa r n i n g !
Always replace wheel bolts that are damaged or
rusted.Never apply oil or grease to wheel bolts.Damaged wheel hub threads should be repaired
immediately.Incorrect mounting bolts or improperly tightened
mounting bolts can cause the wheel to come off.
This could cause an accident. Be sure to use the
correct mounting bolts.

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
+3 psi (+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 underinf lated 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
(including the spare tire) at intervals of no more than
14 days are therefore essential.
