• The compact spare ti re is for temporary use only and is so
marked on the sidewalls .
• Do not d riv e at speeds e xceeding 50 mph (80 km/h ) with the
compact spare wheel mounted . Also rapid acceleration, hard
braking and hard corne ring must be avoided to help prevent loss
of vehicle control.
• Any continuous road use of the compact spare tire may result
in tire failure, los s of vehicle control and injury to vehicle occu ­
pants.
• Do not put a snow chain on your compact spare tire. Due to the
smaller tire size, the chain will not fit properly and can thus
damage your vehicle. You could also lose th e chain, as well as
control of the vehicle .
• If you have a flat front tire in road cond itions which require
snow chains , first remove the undamaged rea r wheel and mount
the compact spare wheel in its place . Then remove the damag ed
front wheel, take the snow chains off it and attach them to the
wheel taken from the rear. Thi s wheel can now be mounted on the
front with its snow chains. Check and adjust tire pressure
promptly.
• Never use two or more compact spare tires at the same time .
0 Note
When using the compact spare wheel, note the following:
• After i nstalling the compact spare w heel, the t ire inflation pres­
sure should be checked and, if necessary, increased to 60 ps i
(4.2

Wheel change
Before changing a wheel
Observe the f oll owing pre cautions for your own and your
passenger's safety when changing a whee l.
- After you exper ience a t ire fa ilure, pu ll t he ca r well away
from movin g traf fic and try to reach
level grou nd before
you stop => & .
- All p asse ngers s hou ld
leave the car a nd move to a safe
locat ion (for instance, beh ind th e guardrai l) => & .
- Apply the
parking brake fi rmly=> &.

What do I do now? -________________ Vflll
- 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 and the spare tire=> page 270 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
transmission in "P" (Park), or engaging a gear in a manual trans­
mission 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. •

change: alignment pin
inside the top hole
After you have loosened all wheel bolts and jacked the vehicle
off the ground, perform the following steps to remove and
replace the wheel:
Removing the wheel
- Use the hexagonal socket in the screwdriver handle to
completely turn out the topmost wheel bolt and set it
aside on a
clean surface=> fig. 191. -
Screw the threaded end of the
alignment pin from the
tool kit hand-tight into the now vacant bolt hole
=> fig. 192.
- Then completely unscrew the other wheel bolts as
described above.
- Take off the wheel leaving the alignment pin in the bolt
hole=> &.
Putting on the spare
- Lift the spare wheel up and carefully slide it over the align­
ment pin to guide it in place.
- Use the hexagonal socket in the screwdriver handle to
screw in and tighten all wheel bolts
slightly.
Unscrew the alignment pin and insert and tighten the
remaining wheel bolt slightly like the rest.
- Turn the handle on the jack counter-clockwise to lower the vehicle until the jack is fully released.
- Use the wheel bolt wrench to tighten all wheel bolts firmly
=>
page 276. Tighten them crosswise, from one bolt to
the (approximately) opposite one, to keep the wheel
centered.
& WARNING
When removing or installing the wheel, the rim could hit the
brake rotor and damage the rotor. Work carefully and have a
second person help you.
(I) Tips
Never try and use the hexagonal socket in the handle of the screw-
driver to loosen or tighten the wheel bolts.

General information of starting
assistance
Please observe that the procedure descr ibed below for connect ing
jumpe r cab les is intended to p rovide a ju mp s tart for your ve hicl e.
Make sure t hat the co nnected clamps have suff ic ient
metal contact.
Sta rt assistance differs for vehicles w ith a 4-cylinde r engine:
=> page 288, "Use of jumper cables"
Safety first
& WARNING
Improper handling of the jumper cables can lead to an explosion
of the battery and severe injurie s. To reduce the ri sk of injury, note
the following:
• The section s of the terminal clamps that are not insul ated
must not touch each other. In addition, the cable clamped to the
battery' s po sitive terminal must not come in contact with electri­
cally connected parts of the veh icle -danger of short circu it!
• Route the jumper cable so that it cannot catch in any rotating
parts in the engine compartment .
• Do not bend over the batteries -danger of chemical burns!
• The battery cell locking screws must be tightened securely.
• Keep ignition source s (open flame , burning cigarettes, etc.)
away from the batteries -danger of explosion!
• Do not clamp the minus cable to parts of the fuel system or the
brake lines.
0 Note
If you prov ide sta rt assistance for others with your vehi cle, you shou ld
not clamp the minus cable( -) to the negative te rm inal of the
discharged batte ry =>

in "General information of s tarting assista nce" on
page 287.
5. Connect the other end of the red jumper cable to the posi­
tive terminal @ of the booster battery @.
6. Connect one end of the black jumper cable, preferably at the ground point. Otherwise, connect it to the negative
terminal ® of the booster battery @.
7 . Connect the other end of the black jumper cable to the
ground point (bolt head ) 0 in your vehicle @.
8. Route the jumper cables so that they cannot catch in any
rotating parts in the engine compartment.
Starting the engine
9. Start the engine of the vehicle providing assistance and
allow it to run at idle.
10. Now start the engine of the vehicle with the discharged battery, wait for two to three minutes until the engine
"runs" smoothly.
