• Turn the jack handle clockwise unt il the jack
arm just fits underneath the rib running
along the underbody
c::> & ..
• Align the jack so that the jack arm claw
c:;, fig. 186 @fits snugly around the unde r­
body rib and the movab le base plate ® sits
flat on the ground. The base @ must be
ver­
tical
under the lifting point @.
• Wind the jack up further until the flat wheel
comes off the ground
c::> . & ..
Recesses at the front and rear of the under­
body rib mark the proper mo unting locations
for the jack
c:;, fig. 185 . There is only one des­

Do not apply the jack anywhere else c::> .&. .
The jack shou ld be positioned approximate ly
6 in. (15 cm) behind the front wheel or 10 in.
(25 cm) in front of the rear wheel.
An
unstable surfa ce under the jack can cause
the vehicle to slip off the jack . Always provide
a firm base for the jack on the ground . If nec­
essary place a sturdy board or sim ilar support
under the jack. On
hard , slipper y su rf a ces

while changing a wheel if you do not fol ­
low safety precautions:
- Mounting the jack under the vehicle at
any other place than indicated above
may damage the vehicle or may result

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 screwdriv·
er handle
to completely turn out the top­
most wheel bolt and set it aside on a
clean
surface c;, fig. 187 .
.,. Screw the threaded end of the alignment
pin from the tool kit hand-tight into the
now vacant bolt hole <=>
fig. 188 .
.,. Then completely unscrew the other wheel
bolts as described above.
.,. Take off the wheel leaving the alignment
pin in the bolt hole
c;, &,.
Putting on the spare
.,. Lift the spare wheel up and carefully slide it
over the alignment 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-clock­
wise to lower the vehicle until the jack is
fully released .
.,. Use the wheel bolt wrench to tighten all
wheel bolts firmly
r:::;, page 238 . Tighten
them
crosswise , from one bolt to the (ap­
proximately) opposite one, to keep the
wheel centered.

A WARNING ,~ -
When removing or install ing the wheel,
the rim could hit the brake rotor and dam­
age the rotor. Work ca refully and have a
second p erson help yo u.
@ Tips
Never try and use the hexagonal socket in
the hand le of the screwdrive r to loosen or
tighten the whee l bolts .
- Pull the reversib le blade from the screw­
drive r bef ore yo u use the hexagonal
socket in the handle to t urn t he whee l
bo lts.
- When mounting tires with
unidirectional
tread design
make su re the tread pat­
te rn is pointed the rig ht way
¢ page 241.
-The wheel bolts should be clea n and easy
to tu rn. Che ck for dirt and corro sio n on
t he mat ing surf aces of both the whee l
and the h ub. Remove a ll dirt from these
su rfaces before remo unt ing the wheel.
Tires with unidirectional tread design
Tires with unidire ctional tread de sign must be
mounted with their tread pattern pointed in
the right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare tire wit h a tread pa tte rn
intended for use in a specific direction , pl ease
note the following:
- The direc tion o f rota tion is marked by an a r­
r ow on the side o f the tire.
- If the spare tire has to be i nst alled in the in ­
correct di rection in the even t of a flat tire,
use the spare tire on ly tempo rari ly since the
tire will not be ab le to ac hieve its opt imum
per formance characterist ics w ith regard to
aquapla ning, no ise and wear.
- We recommend that particular attent ion be
paid to this fact dur ing wet weather and
t h at you adjust your speed to matc h road
co ndit io ns.
What do I do now? 241
- Replace the flat ti re with a new one and
have it installed on your vehicle as soon as
possible to restore the hand ling advantages
of a properly pointed direction-dependent
tire .
Notes on wheel change
