612 Practical hintsWhere will I find ...?Vehicle jack
Storage position
Remove vehicle jack from its
compartment.

Turn crank handle in direction of arrow
as far as it will go.
Operational position
Turn crank handle clockwise.
Before storing the vehicle jack in its
compartment:


It should be fully collapsed.


The handle must be folded in (storage
position).
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of 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
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 arm is
fully seated in the jack take-up bracket.
Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.

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 flashers.

Turn the steering wheel so that the
front wheels are in a straight ahead
position.

Remove the SmartKey from the starter
switch.
Vehicles with SmartKey with
KEYLESS-GO*:
Turn off the engine by pressing the
KEYLESS-GO* button once
(page 366).

Open the driver’s door (this puts
the starter switch in position0,
same as with the SmartKey re-
moved from the starter switch). The
driver’s door then can be closed
again.

Have any passenger exit the vehicle at
a safe distance from the roadway.
Mounting the Minispare wheel
i
Open the door only when conditions are safe
to do so.
Warning!
G
The dimensions of the Minispare wheel are
different from those of the road wheels. As
a result, the vehicle handling characteristics
change when driving with a Minispare wheel
mounted. Adapt your driving style accord-
ingly.
The Minispare wheel is for temporary use
only. When driving with Minispare wheel
mounted, ensure proper tire inflation
pressure and do not exceed a vehicle speed
of 50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Center
as soon as possible to have the Minispare
wheel replaced with a regular road wheel.
Never operate the vehicle with more than
one Minispare wheel mounted.
Do not switch off the ESP
® when a Minis-
pare wheel is mounted.

Prepare the vehicle as described
(page 629).

Take vehicle tool kit tray and vehicle
jack out of trunk (
page 611).

Take the Minispare wheel from the
wheel well under the trunk floor
(page 613).
Lifting the vehicle

Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
or other sizeable objects.
One wheel chock is included with the
vehicle tool kit (
page 613).
When changing wheel on a level surface:

Place the wheel chock in front of and
another sizeable suitable object 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 cir-
cumstances require you to do so on a hill,
place the wheel chock and another size-
able suitable object as follows:

Place the wheel chock and another
sizeable suitable object on the downhill
side blocking both wheels of the axle
not being worked on.

Take two-piece wheel wrench 1 out of
the vehicle tool kit tray.
The jack take-up brackets are located di-
rectly behind the front wheel housings and
in front of the rear wheel housings.
