tire ready for use. •
Applies to vehic les: w ith a space -saving spare wheel
Space-saving spare wheel
The compact spare wheel is only intended to be used for
a short time.
Using the space-saving spare wheel
The space -saving spare wheel is only intended for emergencies
until you can reach a repair shop. Replace it as quickly as possible
with a normal wheel.
There are some restrictions on the use of the space -saving spare
wheel
=> ,&. . The space-saving spare wheel has been developed
especially for your type of vehicle. It must not be exchanged for the
space-saving spare wheel from another type of vehicle.
Normal summer or winter tires must not be fitted on the space ­
saving spare wheel rim.
Snow chains
For technical reasons, the use of snow chains on the space-saving
spare wheel
not permitted .
If you do have to drive with snow chains and have a tire failure on a
front wheel, install the space-saving spare wheel in place of a rear
wheel. Install the snow chains on the rear wheel and use it to
replace the defective front wheel.
& WARNING
• After installing the space-saving spare wheel, the tire pressure
must be checked as soon as possible. The tire pressure must be
adapted to the load condition of the vehicle according to the tire .,_

& WARNING (continued)
pressure table - risk of accident! Use the highest tire pressure in
the table.
• Do not drive faster than 50 mph (80 km/h) - risk of accident!
• Avoid full-throttle acceleration, sharp braking, and fast
cornering - risk of accident!
• Never drive using more than one space-saving spare wheel -
risk of accident!
• Normal summer or winter tires must not be fitted on the space­
saving spare wheel rim. •
Wheel change
Before changing a wheel
Follow these points for your own and your passenger's
safety when replacing a wheel.
-After you experience a tire failure, pull the car well away
from moving traffic and try to reach level ground before
you stop => & .
- All passengers should leave the car and move to a safe
location (for instance, behind the guardrail)=>& .
- Apply the parking brake firmly=>&.
- Move selector lever to position Pon an automatic trans-
mission; put manual transmission in first gear =>& .
- If you are towing a trailer: unhitch the trailer from your
vehicle.
- Take the tool case and the spare tire=>
page 290 out of
the luggage compartment.
& WARNING
You or your passengers could be injured while changing a wheel if
you do not follow these safety precautions:
• If you have a flat tire, move a safe distance off the road. Turn off
the engine, turn the emergency flasher on and use other warning devices to alert other motorists .
• Make sure that passengers wait in a safe place away from the
vehicle and well away from the roadway and traffic.
• To help prevent the vehicle from moving suddenly and possibly
slipping off the jack, always fully set the parking brake and block
the wheel diagonally opposite the wheel being changed. When one
front wheel is lifted off the ground, placing the Automatic Trans­
mission in "P" (Park), or engaging a gear in a manual transmission
will
not prevent the vehicle from moving .
• Before you change a wheel, be sure the ground is level and firm.
If necessary, use a sturdy board under the jack.
• After installing the spare wheel, make sure that you remount
the flat tire/wheel in its storage area properly and tighten the
knurled retaining screw securely. •
Changing a wheel
When you change a wheel, follow the sequence described
below step-by -step and exactly in that order.
1. Remove the decorative wheel cover*. For more details
see also =>
page 294, "Decorative wheel covers" or
=>
page 295, "Wheels with cap-covered wheel bolts".
2. Loosen the wheel bolts=>
page 295.
3. Locate the proper mounting point for the jack and align
the jack below that point=>
page 296.
4. Lift the car with the jack=> page 296. _,..

After changing a wheel
A wheel change is not complete without the following
actions.
- Store and secure the replaced wheel in the spare wheel
well.
- Put the tool case and the jack back in place in the luggage
compartment .
- Check the
tire pressure on the spare wheel immediately
after mounting it.
- As soon as possible , have the
tightening torques on all
wheel bolts checked with a torque wrench. The correct
tightening torque is 90 ft lb (120 Nm).
- Have the flat tire
replaced as soon as possible.
[ i ] Tips
• If you notice while changing a tire that the wheel bolts are
corroded and difficult to turn, then they should be replaced before
you check the tightening torque.
• Drive at reduced speed until you have the tightening torques
checked .•

& WARNING
• Using force without control to speed the wheel change up can
cause the vehicle to slip off the jack and cause serious personal
injuries.
• Do not loosen the wheel bolts more than one turn before you
raise the vehicle with the jack. -Risk of injury!
[ i ] Tips
• Never try and use the hexagonal socket in the handle of the
screwdriver to loosen or tighten the wheel bolts.
• If a wheel bolt sits very tight, you may find it easier to loosen by
carefully pushing down on the end of the wheel bolt wrench with
one foot only . As you do, hold on to the car to keep yourself stable
and take care not to slip.•
Raising the vehicle
The vehicle must be lifted with the jock first before the

point
that is closest to the wheel to be changed
~ fig. 219.
- Turn the
jack handle clockwise until the jack arm just fits
underneath the rib running along the underbody
~ &,.
- Align the jack so that the jack arm claw~ fig. 220 @fits
snugly around the underbody rib and the movable base

- Wind the jack up further until the flat wheel comes off the
ground~ &-
Recesses at the front and rear of the underbody rib mark the proper
mounting locations for the jack => fig. 219. There is only one desig­
nated jack mounting point for each wheel. Do not apply the jack
anywhere else=>& .
The jack should be positioned approximately 6 in. (15 cm) behind
the front wheel or 10 in. (25 cm) in front of the rear wheel.
An
unstable surface under the jack can cause the vehicle to slip off
the jack . Always provide a firm base for the jack on the ground. If
necessary place a sturdy board or similar support under the jack. On
hard, slippery surfaces (such as tiles) use a rubber mat or similar to
prevent the jack from slipping=>& . .,,

- Use the wheel bo lt wrench to tighten all wheel bo lts
firmly=>
page 295. Tighten crosswise, from one bolt to
the (approx imately) oppos ite one, to keep the wheel
centered.
[ i ] Tip s
Never try and use the hexagona l socket in the handle of the screw­
driver to loosen or tighten the wheel bolts.
• Pull the reversible b lade from the screwdriver before you use the
hexagonal socket in the handle to turn the wheel bo lts.
• When mounting tires with
uni dire cti on al tread desig n make sure
the tread pattern is pointed the right way~
page 298.
• The whee l bolts should be clean and easy to turn. Check for dirt
and corrosion on the ma ting surfaces of both the wheel and the
hub. Remove all dirt from these surfaces before remounting the
wheel. •
Tires with unidirectional tread design
Tires with unidirectional tread design must be mounted
with their tread pattern pointed the right direction.
U sin g a spa re tire wit h a tre ad p atte rn int ended for u se
i n a sp ec ific dir ection
When using a spare tire with a tread pattern intended for use in a
specific direction, please note the following:
• The direction of rotation is marked by an arrow on the side of the
tire.
• If the spare tire has to be installed in the incorrect direction in the
event of a flat tire, use the spare tire on ly temporarily since the tire
will not be able to achieve its optimum performance characteristics
with regard to aquaplaning, noise and wear.
• We recommend that particular attention be paid to this fact
dur ing wet weather and that you adjust your speed to match road
conditions.
• Replace the flat tire with a new one and have it instal led on your
vehic le as soon as possible to restore the handling advantages of a
proper ly pointed direction-dependent tire. •
Notes on wheel change
Please read the information~ page 279, "New tires and replacing
tires and whee ls", if you are going to use a spare tire which is
different from the tires on your veh ic le.
