_& WARNING
Impr oper use of the vehicle jack can cause se­
rious personal injur ies.
- Never use the screw driver hex head to
tighten wheel bolts, since the bolts cannot
attain the necessary tightening torque if you
use the hex head, potentially causing an ac­
cident.
- The factory-supp lied jack is intended only
for your vehicle mode l. Under no circum­
stances should it be used to lift heavy
veh icles or other loads; you risk injuring
yourself.
- Never start the engine when the vehicle is
raised, which cou ld cause an accident.
- Support the vehicle securely with appropri­
ate stands if work is to be performed under­
neath the vehicle; otherwise, there is a po­
tential risk for injury.

Loosening the wheel bolts
Fig. 284 Wheel: loosening the wheel bolt
• Slide the wheel wrench (from the vehicle tool
kit) all the way onto the wheel bolt.
• Turn the wheel bolt approximately one turn to
the left -arrow-. To reach the required torque,
hold the end of the wheel wrench. If the wheel
bolt will not loosen, press carefully on the
whee l wrench with your foot. Hold onto the ve­
hicle securely while during this and make sure
your stance is stable .

• Place the veh icle jack* (vehicle tool kit) on a
firm s urface. Use a flat, stable support if neces­
sary. On a slippery surface such as tile, you
should use a non-slip pad (such as a rubber
mat)¢ &.
• Find the marking on the sill that is closest to
the tire that will be
changed¢ fig. 2 85 . Behind
the marking, there is a lifting point on the side
sill for the vehicle jack*.
• Turn the handwheel to raise the vehicle jack*
under the lifting point on the side sill until the
bracket on the jack @ completely covers the
notch on your vehicle.
• Align the vehicle jack* so the bracket @covers
the notch and the base ® is flat on the ground.
The base ® must be directly under the lifting
point @.
• Mount the crank on the vehicle jac k*: insert the
crank into the opening on the handwheel. Turn
the crank to the left or right to secure it.
