Emergency assistance

Raising the vehicle
Applies to: vehicles with vehicle jack





Fig. 178 Sill: positioning the vehicle jack
> Place the vehicle jack from the vehicle tool kit
ona firm surface. Use a flat, stable support if
necessary. On a slippery surface such as tile,
you should use a non-slip pad such as a rubber
mat > /\.
> Find the marking on the sill that is closest to
the tire that will be changed > fig. 177. Behind
the marking, there is a lifting point on the side
sill for the vehicle jack.
> Raise the vehicle jack under the lifting point on
the side sill until the bracket on the jack @)
completely covers the notch on the vehicle.
> Align the vehicle jack so the bracket @ covers
the notch and the base (2) is flat on the ground.
The base @) must be directly under the mount-
ing point @.

ZA WARNING
—To reduce the risk of injury, make sure no
one is in the vehicle before raising it.
— Make sure the vehicle jack is stable. The risk
of injury is increased when the ground is
slippery or soft, because the vehicle jack
could slide or sink.
— Only raise your vehicle with the vehicle jack
provided by the factory. If you use a vehicle
jack designed for another vehicle, your vehi-
cle could slip and cause injury.
— Position the vehicle jack only at the desig-
nated mounting points on the side sill and
align the jack. Otherwise, the vehicle jack
could slip and cause an injury if it does not
have sufficient hold on the vehicle.
—To reduce the risk of injury, do not raise any
other vehicles or other loads using the vehi-
cle jack provided by the factory.
— Applies to: vehicles with air suspension:
Changes in temperature or load can affect
the height of the stopped vehicle.
—To reduce the risk of an accident, never start
the engine when the vehicle is raised.
—To reduce the risk of injury, no work should
be performed under the vehicle while it is
raised.

() Note
Do not lift the vehicle by the sill. Position the
vehicle jack only at the designated mounting
points on the side sill. Otherwise, your vehicle
could be damaged.
