For safety reasons, switch off wipers and
remove SmartKey from starter switch (vehi-
cles with KEYLESS-GO*: Make sure the
vehicle’s on-board electronics have

Otherwise the motor could suddenly turn on
and cause injury.
Warning!
G
Wiper blades are components that are sub-
ject to wear and tear. Change 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 arms
are 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.
Make sure the wiper blades are properly
installed. Improperly installed wiper blades may
cause windshield damage.
For your convenience, we recommend that you
have this work carried out by an authorized
Mercedes-Benz Light Truck Center.

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
(page 142).

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

Set the parking brake (
page 57).

Set the automatic transmission to park

page 187).

Turn off the engine (
page 39).

Remove the SmartKey from the starter
switch.
Vehicles with KEYLESS-GO*:
Turn off the engine by pressing the
KEYLESS-GO* button once
(page 67).

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.
Warning!
G
The dimensions of the spare wheel
(Minispare wheel or collapsible tire) are dif-
ferent from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a spare wheel
mounted. Adapt your driving style accord-
ingly.
The spare wheel is for temporary use only.
When driving with a spare wheel mounted,
ensure proper tire pressure and do not ex-
ceed a vehicle speed of 50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Light
Truck Center as soon as possible to have the
spare wheel replaced with a regular road
wheel.
Never operate the vehicle with more than
one spare wheel mounted.
Do not switch off the ESP
® when a
Minispare wheel is mounted.
Warning!
G
Vehicles with air suspension package*:
Do not open or close any doors or the
tailgate while mounting a spare wheel. The
vehicle could rise or lower to a previously
selected level. You or others could be
injured as a result.
i
Open door only when conditions are safe to
do so.

Preparing the vehicle
Prepare the vehicle as described
(page 497).Vehicles with Minispare wheel:

Take the wheel wrench, the collapsible
wheel chock, and the vehicle jack out
of the cargo compartment
(page 469).

Take the Minispare wheel out of the
cargo compartment (

Vehicles with collapsible tire
(ML 63 AMG only):

Take the collapsible tire, wheel wrench,
wheel bolts, jack, and electric air pump
out of the cargo compartment
(page 474).Lifting the vehicle
i
Vehicles with collapsible tire:
You can use the power outlet in the cargo com-
partment or in the front of the rear seats to oper-
ate the electric air pump even when the ignition
is switched off, e.g. in order to inflate the col-
lapsible emergency spare tire.
An emergency shut-off feature ensures that the
vehicle’s electrical voltage does not fall below a
minimum level. If the voltage drops to this mini-
mum level, the power outlets are automatically
switched off. This ensures that enough power re-
mains to start the engine.
!
Vehicles with factory-mounted
running-boards*:
Your vehicle is equipped with a scissors-type
jack (located under the cargo compartment
floor) designed for use with factory-mounted
running boards. Only use this jack when jacking
up vehicles with factory-mounted running boards
as otherwise the vehicle’s underbody can be
damaged. See separate instructions for
scissors-type jack.
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 that the jack
arm is fully seated in the jack take-up brack-
et. Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.

Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
or other sizable objects.
One collapsible wheel chock is includ-
ed with the vehicle tool kit
(page 469). For information on set-
ting up the collapsible wheel chock,
see (page 472).
When changing wheel on a level surface:

Place one wheel chock in front of and
another sizeable 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
circumstances require you to do so on a
hill, place the wheel chock and another
sizeable object as follows:

Place the wheel chock and another
sizable object on the downhill side
blocking both wheels of the axle not
being worked on.1Wheel wrench

On wheel to be changed, loosen but do
not yet remove the wheel bolts
(approximately one full turn with wheel
wrench1).
The jack take-up brackets are located di-
rectly behind the front wheel housings and
in front of the rear wheel housings.2Take-up bracket
