Warning!
Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may
lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up
and possibly a fire. G
Warning!
Follow recommended tire inflation pressures.
Do not
underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect
handling and fuel economy, and are more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear
unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are
more likely to become punctured or damaged by road debris, potholes etc. Symbol messages

Safety notes
G
Warning!
The dimensions of the spare wheel are
different 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
accordingly. The spare wheel is for temporary use only.
When driving with a spare wheel mounted,
ensure proper tire inflation pressure and do
not exceed a vehicle speed of 50 mph
(80 km/h).
Contact the nearest authorized Mercedes-
Benz 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 ESC when a spare wheel
is mounted.
Preparing the vehicle
X Whenever possible, park the vehicle in a
safe distance from moving traffic on a hard,
flat surface.
X Turn on the hazard warning flasher.
X Turn the steering wheel so that the front
wheels are in a straight-ahead position.
X Engage the electronic parking brake.
X Shift the automatic transmission into park
position P.
X Turn off the engine.
X Remove the SmartKey from the starter
switch.
or
X Vehicles with KEYLESS-GO: Open the
driver’s door (this puts the starter switch in
position 0, same as with the SmartKey
removed from the starter switch). The
driver’s door can then be closed again.
Open doors only when conditions are safe
to do so.
X Vehicles with KEYLESS-GO: Remove the
KEYLESS-GO start/stop button from the
starter switch.
X Have any passenger exit the vehicle at a
safe distance from the roadway. Open
doors only when conditions are safe to do
so. Flat tire

spare wheel

For information on where to find the

(Y page 412) and ( Y page 413).
i Vehicles without spare wheel are not
factory-equipped with
the tools required for
a wheel change such as a jack or a wheel
wrench. Some tools required for a wheel
change are specific to your vehicle.
Contact an authorized Mercedes-Benz
Center to obtain the tools approved for
your vehicle. This section describes the
wheel change using the tools approved and
recommended for your vehicle.
Lifting the vehicle G
Warning!
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 must always be vertical
when in use, especially on inclines or
declines.
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 make sure the electronic parking
brake is engaged. In addition, block the
wheels with wheel chocks or other sizeable
objects before raising the vehicle with the
jack. Do not disengage the electronic parking
brake while the vehicle is raised.
Make sure that 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.
Never start the engine when the vehicle is
raised.
Also observe the notes on the jack.
X Prevent the vehicle from rolling away by
blocking wheels

with wheel chocks or other
sizeable objects.
When your vehicle is equipped with a wheel
chock, it is included with the vehicle tool kit
(Y page 412). For information on setting up
the collapsible wheel chock, see
(Y page 412).
When changing a wheel on a level surface:
X Place a 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. 466

Always try lifting the vehicle using the jack on
a level surface. However, should
circumstances require you to do so on a hill:
X
Place wheel chocks or other sizeable
objects on the downhill side in front of both
wheels on the side opposite to the side on
which the wheel is to be changed. G
Warning!
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. X
On the wheel to be changed, loosen but do
not yet remove the wheel bolts
(approximately one full turn with wheel
wrench :).
The jack take-up brackets are located directly
behind the front wheel housings and in front
of the rear wheel housings. G
Warning!
The jack is designed exclusively for jacking up
the vehicle at the jack take-up brackets. Make
sure the jack arm is fully seated in the jack
take-up bracket.
If you do not position the jack correctly in the
jack take-up bracket, the vehicle can fall off
the jack and seriously or fatally injure you or
others.
! Do not position the jack on the body of
the vehicle, as this may cause damage to
the vehicle. X
Place jack = on firm ground.
X Position jack = under take-up
bracket ; so that it is always vertical as
seen from the side, even if the vehicle is
parked on an incline. X
Turn crank ? clockwise until jack = is
fully seated in take-up bracket ; and the
jack base evenly meets the ground.
X Jack up the vehicle until the wheel is a
maximum of 1.2 in (3 cm) from the ground.
