Spare wheel
Yo ur vehicle is equip ped with a spare wheel
(deflated full size spare tire) and an accom
panying compressor.
The deflated full size spare tire and com
pressor are located beneath the floor of the
luggage compartment. The spare wheel is
held down by a knurled bolt.
On vehicle' s equipped with a childr en's
bench seat, the seat must be folded back to
allow the spare wheel to be removed -see
page 94.
"Changine a wheel" and "Inflating the de
flated full size spare tire" -see page 267.
266 The
following points must be ob
served when the deflated full size
spare tire is used:
• The deflated full size spare tire is
only designed for brief, temporary
use. Therefore, replace it with a nor
mal wheel as soon as poss ible.
• Never drive at speeds over 50 mph
(80 km/h). Avoid jackrabbit starts, hard bra
king and aggressive turns!
• Do not take the vehicle to automatic car
washes when the deflated full size spare
tire is installed.
• The deflated full size spare tire was de
veloped especially for your vehicle model. It
must not be used on other models. Simi
larly, do not use spare wheels from other ve
hicle models on your car. •
For engineering reasons, snow chains
must not be used on the deflated full size
spare tire.
If the vehicle must be driven with snow
chains, and one of its rear tires is flat, you
will first need to install the collapsible rear ti
re on the front axle. This is because for engi
neering reaons snow chains can only be in
stalled on special winter tires*1) and only
on rear wheels.
After you've installed the spare tire on the
front axle, install the snow chain on the
wheel you've removed from the front axle.
and then install this wheel on the rear axle
in place of the wheel whose tire is flat. As
soon as possible, correct the tire pressure
to the proper setting.
• Never install normal or winter tires on the
deflated full size spare tire rim.
• Never drive the vehicle with more than
one deflated full size spare tire installed.

Inflating the deflated full size
spare tire
• Remove the dust cap from the valve (1 l
by unscrewing it.
• Take the pressure compressor hose out
of the case, and screw the coupling nut se
curely onto the valve.
• Insert the compressor· connector in to
the socket located on the side of the lug
gage compartment or inset it ino the ciga
rette lighter socket -see page 181.
272 •
Turn on the compressor. The required tire
pressure wil be reached within a few min
utes. Use a pressure gauge to check the tire
pressure. Never operate the compressor
for longer than 5 minutes.
Note
Yo u'll find adhesive labels on the deflated
full size spare tire containing i nstn .1ctions for
using the tire as well as information on the
specified tire pressure.
Step S
• Un screw the pressure hose from the val
ve and screw the dust cap back on.
• To lower the vehicle, turn the handle
counter-clockwise until the jack is fully re
leased. Remove jack.
• Then go crosswise from one bolt to
another tightening them firmly.
• If necessary, press the hubcap back onto
the hub of the spare wheel. Step
9
• Slip the plastic cover over the wheel con
taining the flat tire. Then stow this wheel in
the luggage comopartment and secure it so
that it does not shift.
• Carefully observe the points on
page 288 when using the deflated
full size spare tire.
Notes
• The hex socket in the screwdriver can be
used to make it easier to handle the wheel
bolts. To do this, pull out the revers ible bla-
de. ·
Never use this plastic tool to loosen
or tighten the wheel bolts.
After you change a tire:
• Deactivating the jack moda -see
page 268.
• Use a torque wrench to check the
wheel bolt tightening torque as
soon as possible. With alloy wheels
and a deflated full size spare tire, the
torque should be 88.5 ft-lb (120
Nm).

•
Be sure to check the tire pressure
as quickly as possible after you
install a wheal that is fitted with
new tires.
If you notice while changing a tire
that the wheal bolts are corroded
and difficult to turn, then they
should be replaced before you
check the tightening torque.
Until then, drive with extra care and
at reduced speeds. m
WARNING
• If you are going to equip your ve
hicle with tires or rims which dif
fer from those which were factory
installed, then be sure to read the
information on page 257.
• Always store damaged wheel,
jack and tools securely in luggage
compartment. DO-IT-YO
