A wheel change is no t complete without the
doing the following .
.. Always store the vehicle tool kit, the jack*
and the replaced tire in the luggage com­
partment ¢
page 134.
.. Check the tire pre ssur e on the spare wheel
immediately after mount ing it .
.,. As soon as possible, have the
tightening
torqu es
on all wheel bol ts checked with a
torq ue wrench. The correct tightening tor ­
que is 90 ft lb (120 Nm) .
.. Have the flat tire
replaced as soon as possi­

corroded and difficult to t urn while
changing a t ire, they should be replaced
before you check the tighten ing torque.
- Drive at reduced speed unt il you have the
tightening torques checked .
