jack must be positioned vertically, directly
under the jacking point of the vehicle.
! The jack is designed exclusively for
jacking up the vehicle at the jacking points.
Otherwise, your vehicle could be damaged.
The following must be observed when raising
the vehicle:
R to raise the vehicle, onl yuse the vehicle-
specific jack that has been tested and
approved by Mercedes-Benz.Ifu sed
incorrectly, the jack could tip over with the
vehicle raised.
R the jack is designed only to raise and hold
the vehicle for a short time while a wheel
is being changed. It is not suited for
performing maintenance work under the
vehicle.
R avoid changing the wheel on uphill and
downhill slopes.
R before raising the vehicle, secure it from
rolling away by applying the parking brake
and inserting wheel chocks. Never
disengage the parking brake while the
vehicle is raised.
R the jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a
large, load-bearing underlay must be used.
On a slippery surface, a non-slip underlay
must be used, e.g. rubber mats.
R do not use wooden blocks or similar
objects as a jack underlay.O therwise, the
jack will not be able to achieve its load-
bearing capacity due to the restricted
height.
R make sure tha tthe distance between the
underside of the tires and the ground does
not exceed 1.2 in (3 cm).
R never place your hands and feet under the
raised vehicle.
R never lie under the raised vehicle.
R never start the engine when the vehicle is
raised. R
never open or close a door or the trunk lid
when the vehicle is raised.
R make sure that no persons are present in
the vehicle when the vehicle is raised. X
Using lug wrench 0003, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts
completely. The jacking points are located just behind the
front wheel housings and just in front of the
rear wheel housings (arrows). Covers, front (example: vehicles with AMG

Lowering the vehicle G
WARNING
The wheels could work loose if the wheel nuts
and bolts are not tightene dto the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed. X
Turn the crank of the jack counter-
clockwise until the vehicle is once again
standing firmly on the ground.
X Place the jack to one side.
X Tighten the wheel bolts evenly in a
crosswise pattern in the sequence
indicated (0003 to0021). The specified
tightening torque is 96 lb-ft (130 Nm).
X Turn the jack back to its initial position.
X Stow the jack and the rest of the vehicle
tools in the trunk again.
X AMG vehicles and vehicles with AMG
equipment: insert the cover into the outer
sill.
X Check the tire pressure of the newly
installed wheel and adjust it if necessary.
Observe the recommended tire pressure
(Y page 311).
i Vehicles with tire pressure loss warning
system: as long as you are driving with an
emergency spare wheel, the tire pressure
loss warning system cannot function
reliably .Only restart the tire pressure loss
warning system when the defective wheel
has been replaced with a new wheel.
i Vehicles with tire pressure monitor: all
wheels mounted must be equipped with
functioning sensors. 334

An emergency spare wheel may also be
mounted against the direction of rotation.
Observe the time restriction on use as well as
the speed limitation specified on the
emergency spare wheel.
Replace the tires after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel.
i When you are driving with the collapsible
spare wheel mounted, the tire pressure
loss warning system or the tire pressure
monitor cannot function reliably. Only
restart the tire pressure loss warning
system/the tire pressure monitor when the
damaged wheel has been replaced with a
new wheel.
Vehicles with tire pressur emonitor:
after mounting an emergency spare wheel,
the system may still display the tire
pressure of the removed wheel for a few
minutes .The value displayed for the
mounted emergency spare wheel is not the
same as the current tire pressure of the
emergency spare wheel. Removing the emergency spare wheel
Example
The collapsible spare wheel can be found in
the stowage well under the trunk floor. X
Turn retaining screw 0004counter-clockwise
and remove it.
X Remove collapsible spare wheel 0003. AMG vehicles
AMG vehicles:
the collapsible spare wheel is
packed in a bag and secured to a bracket in
the trunk.
X Loosen tensioning straps 0003on both sides.
X Unhook retaining spring hooks 0004and 0024
tensioning strap 0003from the bracket.
X Remove the bag with the collapsible spare
wheel.
X Open the bag and remove the collapsible

Information on the tire-change tool kit can be
found in the "Where will Ifind...?" section
(Y page 291). Stowing the emergency spare wheel
! Only place the collapsible spare wheel in
the vehicle when it is dry. Otherwise,
moisture may get into the vehicle.
Take the following steps to stow a used
collapsible spare wheel. Otherwise, the
collapsible spare wheel will not install in the
trunk in the intended manner. Mercedes-
Ben zrecommends that you have this work
carried out at a qualified specialist workshop.
X Unscrew the valve cap from the valve.
X If possible, unscrew the valve insert from
the valve and release the air. 340

X Inflate the tire to the specified tire
pressure.
The specified tire pressure is printed on the
yellow label of the emergency spare wheel.
X When the specified tire pressure has been
reached, press on/offs witch0021toOFF , on
