Warning!
The jack is designed exclu­
sively for jacking up the
vehicle at the jack tubes
built into either side of the
vehicle. Use the jack only to
lift the vehicle during a
wheel change. Never get
beneath the vehicle while it
is supported by the jack.
Keep hands and feet away
from the area under the lifted
vehicle. Always firmly set
parking brake and block
wheels before raising vehicle
with jack.
Do not disengage parking
brake while vehicle is raised.
Be certain that the jack is
always vertical when in use,
especially on hills. Lower the
vehicle onto sufficient capa­
city jackstands before
working under the vehicle.
9. Unscrew wheel bolts completely.
Keep bolt threads protected from
dirt and sand. While removing
last bolt, hold wheel against hub
to avoid paint damage on rim.
10. Remove wheel.
11. Screw the alignment bolt (sup­
plied in tool kit) into the upper­
most threaded hole.
12. Adjust the jack height so that the
wheel can be slipped on without
being lifted.
13. Install spare wheel on wheel
hub. Insert wheel bolts and
tighten them slightly.
To avoid paint damage, place
wheel flat against hub and hold it
there while installing first wheel
bolt. Unscrew the alignment bolt
to install the last wheel bolt.
14. Lower car, remove jack.
15. Place protective cap into the jack
support tube.
16. Tighten the five bolts evenly,
always skipping one, until all
bolts are tight. Observe a tight­
ening torque of 110 Nm
(80 ft.lb.).
17. Correct tire pressure.
W arning!
Incorrect mounting bolts or
improperly tightened mounting
bolts can cause the wheel to
come off. This could cause an
accident. Be sure to use the
correct mounting bolts.
Important!
When installing new wheels the
mounting bolts must be retightened
after approx. 100-500 km
(60-300 miles). Observe a tightening
torque of 110 Nm (80 ft.lb.).
