WHEELS AND TYRES
||
WARNING
Apply the parking brake and set the
•
gear selector in Park position (P).
Chock the wheels standing on the
•
ground using solid wood blocks or
large stones.
Check that the jack is not damaged,
•
that the threads are thoroughly lubri-
cated and that it is free from dirt.
Check that the jack is resting on a firm,
•
level surface that is not slippery and is
not slanted.
The jack must be correctly attached in
•
the jack's bracket.
Never position anything between the
•
ground and the jack, nor between the
jack and the car's jacking point.
Passengers must leave the car when it
•
is raised on the jack.
If a wheel must be changed in a traf-
•
ficked environment, passengers must
stand in a safe place.
Use a jack designed for the car when
•
changing tyres. Use supports to secure
the car for all other work.
Never crawl under the car or reach
•
under with a part of your body when it
is raised on a jack.

The car needs to be raised high enough so
that the wheel to be loosened can roll freely.
1.
Clean the surfaces between wheel and
hub.
2. Put on the wheel. Tighten the wheel bolts
thoroughly.
Do not use lubricant on the threads of the
wheel bolts.
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
(103 foot-pound). Check the tightening
torque with a torque wrench.
5. Refit the plastic caps on the wheel bolts.
6. Check the tyre pressure and save the new
tyre pressure in the system for tyre pres-
sure monitoring*.
WARNING
The wheel bolts may need to be re-tight-
ened several days after the change. Tem-
perature differences and vibration may
mean that they are not attached equally as
tightly.
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.
