Securing the vehicle against rolling
away
If your vehicle is equipped with a wheel chock, it
can be found in the tyre-change tool kit
(Y page 325).
The folding wheel chock is an additional secur-
ing measure to safeguard the vehicle from roll-
ing away, e.g. during a wheel change.
X Fold both plates upwards :.
X Fold out lower plate ;.
X Insert the lugs on the lower plate fully into the
openings in base plate =.X
Place chocks or other suitable items under
the front and rear of the wheel that is diago-
nally opposite the wheel you wish to change.
Raising the vehicle G
WARNING
If you do not position the jack correctly at the appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack must be positioned vertically, directly under
the jacking point of the vehicle.
Observe the following when raising the vehi- cle:
R only use the vehicle-specific jack that has
been tested and approved by Mercedes-Benz
to raise the vehicle. If the jack is used incor-
rectly, it could tip over while the vehicle is
raised.
R the jack is designed only to raise the vehicle
for a short time while a wheel is being
changed. It is not permissible to use it to per-
form maintenance work under the vehicle.
R avoid changing the wheel on uphill and down-
hill slopes.
R before raising the vehicle, secure it from roll-
ing away by applying the parking brake and
positioning wheel chocks. Do not release 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,
flat load-bearing underlay must be used. On a
slippery surface, a non-slip underlay must be
used, e.g. use a rubber mat on tiles.
R do not use wooden blocks or similar objects
as a jack underlay. Otherwise, the jack will not
be able to achieve its load-bearing capacity
due to the restricted height.
R make sure that the distance between the
underside of the tyres and the ground does
not exceed 3 cm.
R do not place your hands or feet under the
raised vehicle.
R do not lie under the raised vehicle.
R do not start the engine when the vehicle is
raised.
R do not open or close a door or the boot lid
when the vehicle is raised.
R make sure that no persons are present in the
vehicle when raising the vehicle.
Vehicles with light-alloy wheels and hub
cap: the wheel bolts are covered by a hub cap.
Before you can unscrew the wheel bolts, you
must remove the hub cap. Two different variants
can be fitted. 352
Changing a wheelWheels and tyres

for Mercedes-Benz vehicles and the respective
wheel.
! Mercedes AMG vehicles with ceramic-
brake disc: during removal and repositioning
of the wheel, the wheel rim can strike the
ceramic-brake disc and damage it. Therefore,
take precautions and have a second person
assist you. Alternatively, you can use a sec-
ond centring pin. X
Clean the wheel and wheel hub contact sur-
faces.
X Slide the wheel to be mounted onto the cen-
tring pin and push it on.
X Tighten the wheel bolts until they are finger-
tight.
X Unscrew the centring pin.
X Tighten the last wheel bolt until it is finger-
tight.
Lowering the vehicle G
WARNING
The wheels could work loose if the wheel nuts and bolts are not tightened to 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 anti-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 (: toA).
The tightening torque must be 130 Nm.
X Turn the jack back to its initial position.
X Stow the jack and the rest of the tyre-change
tool kit in the boot again.
X Mercedes-AMG vehicles and vehicles
with AMG equipment:
use the cover of the
outer sill.
X Check the tyre pressure of the newly fitted
wheel and adjust if necessary.
Observe the recommended tyre pressure
(Y page 345).
If you are driving with the emergency spare
wheel fitted, the tyre pressure loss warning sys-
tem or the tyre pressure monitor cannot func-
tion reliably. Restart the tyre pressure loss warn- ing system or tyre pressure monitor only once
the defective wheel has been replaced with a
new wheel.
Vehicles with tyre pressure monitor: all fitted
wheels must be equipped with functioning sen-
sors. Wheel-tyre combination
You can ask for information regarding permitted
wheel/tyre combinations at a Mercedes-Benz
Service Centre.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tyres and wheels
which have been approved by Mercedes-Benz specifically for your vehicle. Wheel-tyre combination
355Wheels and tyres Z

When using an emergency spare wheel or spare
wheel of a different size, you must not exceed
the maximum speed of 80 km/h.
Snow chains must not be fitted to emergency
spare wheels. General notes
You can ask for information regarding permitted
emergency spare wheels at a Mercedes-Benz
Service Centre.
You should regularly check the pressure of all
your tyres, including the emergency spare
wheel, particularly prior to long trips, and cor-
rect the pressure as necessary (Y page 345).
The value on the wheel is valid.
An emergency spare wheel may also be fitted
against the direction of rotation. Observe the
time restriction on use as well as the speed lim- itation specified on the emergency spare wheel.
Replace the tyres after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel.
If you are driving with the emergency spare
wheel fitted, the tyre pressure loss warning sys- tem or the tyre pressure monitor cannot func-
tion reliably. Restart the tyre pressure loss warn-
ing system or tyre pressure monitor only once
the defective wheel has been replaced with a
new wheel.
Vehicles with tyre pressure monitor: after an
emergency spare wheel has been fitted, the sys- tem may still display the tyre pressure of the
removed wheel for a few minutes. The value dis-
played for the position where the emergency
spare wheel is fitted is not the same as the cur- rent tyre pressure of the emergency spare
wheel. Removing the emergency spare wheel
The emergency spare wheel is secured in the
emergency spare wheel bag in the boot.
X Open the boot.
X Detach the securing straps.
X Unhook the spring hooks of the securing
straps from the retainers.
X Remove the emergency spare wheel bag with
the emergency spare wheel.
X Open the emergency spare wheel bag and
remove the emergency spare wheel. Always pay attention to the instructions and
safety notes under "Changing a wheel"
(Y
page 351). Emergency spare wheel
