Wa r n i n g !
The spare wheel rim is for temporary use only. Use
for over a total of 12 000 miles (20 000 km) may
cause wheel rim failure leading to an accident and
possible injuries. The dimensions of the spare wheel are different
from those of road wheels. As a result, the vehicle
handling characteristics change when driving with
a mounted spare wheel.The spare wheel should only be used temporarily,
and replaced with a regular road wheel as quickly
as possible.
Wa r n i n g !
The jack is designed exclusively for jacking up the
vehic l e at t he j a ck ta ke-up brackets bui l t in to ei ther
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 d i sen ga ge park in g b ra ke whi l e the vehic l e 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 seated in the jack take-up bracket. Always
lower the vehicle onto sufficient capacity
jackstands before working under the vehicle.

Move vehicle to a level area which is a safe distance
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 an level road, place one chock in front of
and one behind the wheel that is diagonally
opposite to the wheel being changed.4. Vehicles with steel rims
Removal of wheel cover:
Reach into two opening of the wheel cover and pull.

vehicle tool kit and assemble (see page 305).
6. Using the wrench, loosen but do not yet remove the
wheel bolts.7. Place jack on firm ground. Position jack (1) under
the take-up bracket (2) so that it is always vertical
(plumb-line) as seen from the side, even if the
vehicle is parked on an incline.
The jack take-up brackets are located directly
behind the front wheel housings and in front of the
rear wheel housings.
8. Jack up the vehicle until the wheel is clear of the
ground. Never start engine while vehicle is raised.

9. 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.
10. Remove wheel. Grip wheel from the sides. Keep
hands from beneath the wheels.1Wheel bolt for light alloy rims

Install spare wheel on wheel hub. Insert wheel bolts
and tighten them slightly.
To avoid paint damage, place wheel flat against hub
and hold it there while installing first wheel bolt.
Unscrew the alignment bolt to install the last wheel
bolt.12. Lower vehicle and remove jack.

13. Using the wrench, tighten the five bolts evenly,
following the sequence illustrated, until all bolts are
tight.
Observe a tightening torque of 80 ft.lb. (110 Nm).14. Vehicles with steel rims
Installation of wheel cover:
Position small wheel cover opening over tire valve
and press wheel cover against wheel rim. Now press
(do not hit) opposite side of wheel cover against
wheel rim until seated. Make certain that the
springs of the wheel cover are firmly seated in the
outer rim of the steel wheel.

Before storing the jack, it should be fully collapsed, with
handle folded in.
For proper storage of vehicle jack see page 304.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
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.

If engine does not run after several unsuccessful
starting attempts, have it checked at the nearest
authorized Mercedes-Benz Center.
Excessive unburned fuel may damage the catalytic

Wa r n i n g !
Prior to towing the vehicle with all wheels on the
ground, make certain that the electronic key is in
starter switch position 2.If the electronic key is left in the starter switch
position 0 for an extended period of time, it can no
longer be turned in the switch. In this case, the
steering is locked. To unlock, remove electronic key
from starter switch and reinsert.
