A WARNING
You o r your passengers could be i nju red
while changing a wheel if you do not fo l­
l ow these sa fety precaut ions:
- If you have a flat tire, move a safe dis­
tance off the road. Turn off the engine,
turn the eme rgency flashers on and use
-

other warning devices to alert other mo­
torists.
- Make sure that passengers wait in a safe
place away from the vehicle and well
away from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the
jack, always fully set the parking brake
and block the wheel diagonally opposite
the wheel being changed. When one
front wheel is lifted off the ground, plac­
ing the Automatic Transmission in "P"
(Park) will
not prevent the vehicle from
moving.
- Before you change a wheel, be sure the
ground is level and firm. If necessary,
use a sturdy board under the jack.
- After installing the spare wheel, make
sure that you replace the flat tire/wheel
in its storage area properly and tighten
the knurled retaining screw securely.
@ Tips
Before changing the wheel, you must acti·
vate the jacking mode, so that the auto­
matic controls for the Adaptive Air Sus­
pension do not make it more difficult to
lift the vehicle with the jack ¢
page 265.

A wheel change is not complete without the
doing the following.
.. Store and secure the wheel you replaced in
the spare wheel well.
.. Replace the tools and the jack in their prop­
er location.
.. Check the
tire pressure on the spare wheel
immediately after mounting it.
.. As soon as possible, have the
tightening
torques
on all wheel bolts checked with a
torque wrench. The correct tightening tor­
que is 90
ft lb (120 Nm).
.. Have the flat tire
replaced as soon as possi­
ble .

inte nded for use in a specific direction, please
note t he following:
- T he direction o f rotation is marked by an a r­
r ow on the side of the tire.
- If the spare tire has to be install ed in the in­
correct di rection, use the sp are tire only
temporar ily since the t ire will not be a ble to
achieve its optimum pe rformance character­
ist ics with regard to aquaplaning, noise and
