Warning!G
The dimensions of the collapsible tire are
different from those of the road wheels. As
a result, the vehicle handling characteristics
change when driving with a collapsible tire
mounted. Adapt your driving style accord-
ingly.
The collapsible tire is for temporary use
only. When driving with a collapsible tire
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 Light
Truck Center as soon as possible to have the
collapsible tire replaced with a regular road
wheel.
Never operate the vehicle with more than
one collapsible tire mounted.
Do not switch off the ESP
® when a
collapsible tire is mounted.

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 program*:
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.

Mounting the spare wheel
Preparing the vehicle
Prepare the vehicle as described
(
page 478).
Vehicles with Minispare wheel:
Take the Minispare wheel out of the
cargo compartment (
page 453).
Take the wheel wrench, the collapsible
wheel chock, and the vehicle jack out
of the cargo compartment
(
page 448).
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 454).Lifting the vehicle
iVehicles with collapsible tire (ML 63 AMG
only):
You can use the power outlets, except for the
power outlet in the front center console, to
operate the electric air pump even when the
ignition is switched off, e.g. in order to inflate the
collapsible emergency spare tire (
page 485).
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.
!Depending on vehicle production date your
vehicle may be equipped with a scissors-type
jack (located under the cargo compartment
floor). If so equipped, only use this jack when
jacking up the vehicle as otherwise the vehicle’s
underbody can be damaged. See separate
instructions for scissors-type jack.
Warning!G
When jacking up the vehicle, only use the
jack which has been specifically approved
by Mercedes-Benz for your vehicle.
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. Make
sure the jack arm is fully seated in the jack
take-up bracket.
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 in-
jury, use the jack only to lift the vehicle dur-
ing a wheel change.
Never get beneath the vehicle while it is sup-
ported 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.

Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
or other sizeable objects.One collapsible wheel chock is includ-
ed with the vehicle tool kit
(
page 448). For information on set-
ting up the collapsible wheel chock,
see (
page 452).
Changing wheel on a level surface
Changing rear wheel on passenger side
(Example illustration)
Place the wheel chock in front of and
another sizeable object behind the
wheel that is diagonally opposite to the
wheel being changed.
Changing wheel on a slight decline
Always try lifting the vehicle using the jack
on a level surface. However, should
circumstances require you to do so on a
slight decline, place the wheel chock and
another sizeable object as follows:
Changing wheel on passenger side
(Example illustration)
Always firmly set parking brake and block
wheels with wheel chocks or other sizeable
objects before raising vehicle with jack. Do
not disengage parking brake while the vehi-
cle is raised.
Make sure that the ground on which the ve-
hicle is standing and where you place the
jack is solid, level and not slippery. If neces-
sary, use a large underlay. On slippery sur-
faces, 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 ca-
pacity if it is not at its full height.
Never start the engine when the vehicle is
raised.
Also observe the notes on the jack.
Warning!G
Only jack up the vehicle on level ground or
on slight inclines/declines. Otherwise, the
vehicle could fall off the jack and injure you
or others.
