WARNING
Never crawl under the car when it is raised
on the jack.
Passengers must leave the car when it is
raised on the jack. If a wheel must be
changed in a trafficked environment, pas-
sengers must stand in a safe place.
NOTE
The normal car jack is only designed for
occasional, short-term use, such as when
changing a wheel after a puncture, chang-
ing to winter/summer wheels, etc. Only the
jack for the specific car model may be
used to raise the car. If the car is to be
jacked up more often, or for a longer time
than is required just to change a wheel,
use of a garage jack is recommended. In
this instance, follow the instructions for
use that come with the equipment.

WARNING
Never crawl under the car when it is raised
on the jack.

1. Clean the contact surfaces between
wheel and hub.
2. Put on the wheel. Tighten the wheel bolts
thoroughly.
3. Lower the car so that the wheels cannot
rotate.
4. Tighten the wheel bolts crosswise. It is
important that the wheel bolts are tight-
ened properly. Tighten to 140 Nm. Check
the torque with a torque wrench.
5. Refit the plastic caps on the wheel bolts.
6. Refit any full wheel covers.
NOTE
•
After a tyre has been inflated, always
refit the dust cap in order to avoid
damage to the valve from gravel, dirt,
etc.
•
Only use plastic dust caps. Metal dust
caps can rust and become difficult to
unscrew.
