page 290).
Lifting the vehicle

Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
(not included) or other sizable objects.
When changing wheel on a level surface:

Place one chock in front of and one be-
hind the wheel that is diagonally oppo-
site to the wheel being changed.
When changing wheel on a hill:

Place chocks on the downhill side
blocking both wheels of the other axle.
Wheel wrench
On wheel to be changed, loosen but do
not yet remove the wheel bolts (ap-
proximately one full turn with wrench).
Warning!
G
The jack is designed exclusively for jacking
up the vehicle under the axle housing. To
help avoid personal injury, use the jack only
to lift the vehicle during a wheel change.
Never get beneath the vehicle while it is sup-
ported 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 the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use, es-
pecially on hills. Always try to use the jack
on level surface. Make sure that the jack is
positioned correctly under the axle housing.
Always lower the vehicle onto sufficient ca-
pacity jackstands before working under the
vehicle.
If the vehicle is not raised as described, it
could slip off the jack as a result of vibra-
tions (e.g. opening or closing a door or the
tailgate).

300 Practical hintsTowing the vehicleWarning!

With the engine not running, there is no
power assistance for the braking and steer-
ing systems. In this case, it is important to
keep in mind that a considerably higher de-
gree of effort is necessary to brake and
steer the vehicle. Adapt your driving accord-
ingly.iThe selector lever will remain locked in
positionP and the key will not turn in
the starter switch if the battery is dis-
connected or discharged. See notes on

ard warning flasher will operate again.
!When towing the vehicle with all wheels
on the ground, note the following:
With the automatic central locking acti-
vated and the key in starter switch
position2, the vehicle doors lock if the
wheels are turning at vehicle speeds of
approx. 9 mph (15 km/h) or more.
To prevent the vehicle doors from lock-
ing, deactivate the automatic central
locking (
page 128).
Towing of the vehicle should only be
done using the towing eye. Never at-
tach tow cable, tow rope or tow rod to
vehicle chassis, frame or suspension
parts.
