WARNING
When jacking up the vehicle, only use a
suitable jack. Observe the manufacturer’s
safety instructions.
The jack must be designed for jacking up
this vehicle at the jack take-up brackets
built into both sides of the vehicle.
The jack is intended only for lifting the
vehicle briefly for wheel changes. It is not suited for performing maintenance work
under the vehicle. 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
supported by the jack. Keep hands and feet
away from the area under the lifted vehicle.
Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.
Always firmly engage the parking brake and block the wheels with wheel chocks or othersizeable objects before raising the vehi-
cle with the jack. Do not release the parking
brake while the vehicle is raised.
Make sure the ground on which the vehicle
is standing and where you place the jack is solid, level and not slippery. If necessary,
use a large underlay. On slippery surfaces, such as tiled floors, you should use a non-
slip underlay, for example a rubber mat.
Do not use wooden blocks or similar objects
to support the jack. Otherwise the jack may
not be able to achieve its load-bearing
capacity if it is not at its full height.
The jack must always be vertical when in
use. Always try to use the jack on level sur- face. If you do not position the jack cor-
rectly, the vehicle can fall off the jack and
seriously or fatally injure you or others.
Never switch on the drive system when the
vehicle is raised.
Also observe the notes on the jack.
X Make sure to have a suitable jack 10
, wheel
wrench 10
and wheel chock 10
.
Contact an authorized electric drive
smart center for information on which
jack and wheel wrench are required.
X Prepare the vehicle as described
(Y page 195).
X Make sure the surface is level.
Prevent the vehicle from rolling away by
blocking wheels with wheel chocks or other sizeable objects:
X Place one wheel chock or other sizeable
object in front of and another wheel
chock or other sizeable object behind
the wheel that is diagonally opposite to
the wheel being changed.
X On wheel to be changed, loosen but do not
yet remove the wheel bolts (approx-
imately one full turn with wheel wrench).
! Only position the jack on the designa-
ted take-up brackets.
You must not position the jack under the
high-voltage battery. Otherwise, the
high-voltage battery could be damaged.
