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.

Introduction
XPrepare the vehicle as described
( Y page 508).XTake the following out of the vehicle:
R spare wheel
R jack
R vehicle tool kit
For information on where to find the
respective items, see “Where will I find ...?”
( Y page 450) and ( Y page 451).
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
GWarning!
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.XPrevent 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 450). For information on setting up
the collapsible wheel chock, see
( Y page 450).Flat tire509Practical hints221_AKB; 6; 20, en-USd2ugruen,Version: 2.11.8.12009-09-24T13:28:17+02:00 - Seite 509Z

vehicle’s internal electrical functions
before you disconnect or remove the
battery’s terminal clamps. You could
otherwise destroy electronic assemblies
such as the generator.
Remove SmartKey from starter switch
(vehicles with KEYLESS-GO: Make sure the
vehicle’s on-board electronics have status 0)
when you turn off the engine and no longer
require any electrical consumers. The vehicle
then uses very little power and the battery is
spared.
If the battery is discharged, you must use the
mechanical key to unlock the vehicle.
Charging the battery
GWarning!
Never charge a battery while still installed in
the vehicle unless the accessory battery
charge unit approved by Mercedes-Benz is
