For safety reasons, switch off wipers and
remove SmartKey from starter switch
before replacing a wiper blade. Otherwise,
the wiper motor could suddenly turn on and
cause injury.

Wiper blades are components that are
subject to wear and tear. Replace the wiper
blades twice a year, preferably in the spring
and fall. Otherwise the windows will not be
properly wiped. As a result, you may not be
able to observe surrounding traffic condi-
tions and could cause an accident.
!Never open the hood when the wiper arm is
folded forward.
Hold on to the wiper when folding the wiper arm
back. If released, the force of the impact from
the tensioning spring could crack the windshield.
Do not allow the wiper arms to contact the wind-
shield glass without a wiper blade inserted.

Flat tire
When you replace the vehicle’s tires, you
can use the spare wheel as a regular wheel
if:

it is not more than 6 years old

rim and tire are the same model as the
regular wheels
Preparing the vehicle
Park the vehicle in a safe distance from
moving traffic on a hard, flat surface
when possible.
Turn on the hazard warning flasher
(

Turn the steering wheel so that the
front wheels are in a straight-ahead
position.
Set the parking brake (page 62).
Move the gear selector lever to park

Mounting the spare wheel
Preparing the vehicle
Prepare the vehicle as described
(
page 390).
Remove the spare wheel from the
spare wheel carrier (
page 368).
Take the vehicle tool kit out of its
storage compartment (
page 366).
Take the vehicle jack out of its storage
compartment (
page 367).Lifting the vehicle
Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
(not included) or other sizeable
objects.
When changing wheel on a level surface:
Place one wheel chock in front of and
one behind the wheel that is diagonally
opposite to the wheel being changed.
Always try lifting the vehicle using the jack
on a level surface. However, should
circumstances require you to do so on a
hill, place the wheel chocks as follows:
Place the wheel chocks on the downhill
side blocking both wheels of the axle
not being worked on.
Warning!G
For your safety, remove spare wheel from
spare wheel carrier before undertaking any
further steps.
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
supported 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,
especially on hills. Always try to use the jack
on level surface.
Make sure the jack is positioned correctly
under the axle housing. Always lower the
vehicle onto sufficient capacity 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).
