An arrow on the sidewall of the tire indicates
its correct direction of rotation.
You may mount a spare wheel against the
direction of rotation. Observe the time restric-
tion on use as well as the speed limitation
specified on the spare wheel. Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the tires
from contact with oil, grease and fuel. Mounting a wheel

from traffic and on a level, firm and non-slip
surface.
X If your vehicle poses a risk to approaching
traffic, switch on the hazard warning lamps.
X Apply the parking brake.
X Turn the front wheels to the straight-ahead
position.
X Shift the transmission to position j.
X Switch off the engine.
X Passengers should leave the vehicle. Make
sure that the passengers are not endan-
gered as they do so.
X Make sure that no one is near the danger
area while the wheel is being changed. Any-
one who is not directly assisting in the
wheel change should, for example, stand
behind the barrier.
X Place the warning triangle or warning lamp
at a suitable distance.
Observe the legal requirements on the cor-
rect use of the warning triangle or warning
lamp for the country in which you are cur-
rently driving
X Secure the vehicle to prevent it from rolling
away.
Observe the safety notes on parking under
"Driving and parking"
(Y page 138)
X On level terrain: place chocks or other suit-
able objects under the front and rear of the
wheel that is diagonally opposite the wheel
to be changed. X
On slight inclines: place chocks or other
suitable objects under the wheels on the
front and rear axles opposite the wheel to
be changed.
X If included in the vehicle equipment, take
the tire-changing tool kit out of the vehicle
tool kit (Y page

270).
Apart from some country-specific variants,
vehicles are not equipped with tire-changing
tools. Some tools for changing a wheel are
specific to the vehicle. Consult a qualified
specialist workshop for more information on
which tools are required to perform a wheel
change on your vehicle.
X If included in the vehicle equipment, remove
the spare wheel from the spare wheel
bracket

risk of injury.
Do not change wheels on uphill or downhill
gradients. Notify a qualified specialist work-
shop.
! Only position the jack on the jacking
points intended for this purpose. You could
otherwise damage the vehicle.
Observe the following when raising the vehi-
cle:
R To raise the vehicle, only use the vehicle-
specific jack that has been tested and
approved by Mercedes-Benz. If the jack is
used incorrectly, it could tip over while the
vehicle is raised.
R The vehicle's jack is intended only to raise
the vehicle for a short time when changing a
wheel. It is not suited for performing mainte-
nance 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 disen-
gage 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 Make sure that the distance between the
underside of the tires and the ground does
not exceed
1.2 in(3 cm).
R Never place your hands or 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 tailgate/

tem: all mounted wheels must be equipped
with functioning sensors.
X Retighten the wheel bolts or wheel nuts to
the specified tightening torque after the
vehicle has been driven for

30 miles
(50 km).
When using a wheel/spare wheel with a new
or newly painted wheel rim, have the wheel
bolts/nuts retightened again after approx-
imately

600 to 3,000 miles (1,000 to
5,000 km). Observe the specified tightening
torque. Wheel and tire combinations
General notes
! Retreaded tires are neither tested nor rec-
ommended by Mercedes-Benz, since previ-
ous damage cannot always be detected on
retreaded tires. As a result, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tires are mounted. Do not mount used tires
if you have no information about their previ-
ous usage.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tires, wheels and accessories which have been approved by
Mercedes-Benz specifically for your vehicle.
These tires have been specially adapted for
use with the driving safety systems, such as
ABS or ESP
®
.
Only use tires, wheels or accessories tested
and approved by Mercedes-Benz. Certain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition,
when driving with a load, tire dimension var-
iations could cause the tires to come into
contact with the bodywork and axle compo-
nents. This could result in damage to the
tires or the vehicle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tires, wheels
or accessories other than those tested and
approved.
Further information on wheels, tires and
approved combinations can be obtained
from a qualified specialist workshop.
! Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll com-
fort and suspension comfort are reduced
and the risk of damage to the wheels and
tires as a result of driving over obstacles
increases.
You will find a table with the recommended
tire pressures for various vehicle loads on the
inside of your vehicle's fuel filler flap or under
"Tire pressure tables"

(Y page 289). You can
find further information under "Tire pressure"
( Y page 282).
Check tire pressures regularly and only when
the tires are cold.
Notes on the vehicle equipment – always
equip the vehicle:
R with tires of the same size across an axle
(left/right)
R with the same type of tires on all wheels at
a given time (summer tires, winter tires)
i Not all wheel/tire combinations can be
installed at the factory in all countries. Wheel and tire combinations

Spare wheel
Important safety notes
G
WARNING
Wheel and tire dimensions as well as the
type of tire can vary between the spare
wheel and the wheel to be replaced. When
the spare wheel is mounted, driving charac-
teristics may be severely affected. There is a
risk of an accident.
In order to reduce risks:
R you should therefore adapt your driving
style and drive carefully.
R never mount more than one spare wheel
that differs from the wheel to be replaced.
R only use a spare wheel that differs from
the wheel to be replaced for a short time.
R do not deactivate ESP ®
.
R have a spare wheel that differs from the
wheel that has been changed replaced at
the nearest qualified specialist workshop.
You must observe the correct wheel and
tire dimensions as well as the wheel type.
When using a spare wheel of a different size,
do not exceed the maximum permissible
speed of
50 mph (80 km/h). General notes
The procedure for mounting the spare wheel is
described in "Mounting a wheel"

(Y page 298).
The following should be checked regularly,
particularly prior to long journeys:
R the tire pressure of the spare wheel, which
should then be corrected if necessary
(Y page 282)
R the fastenings of the spare wheel bracket
The spare wheel is located either in the left
rear compartment or in a spare wheel bracket
under the vehicle.
Replace the tires after six years at the latest,
regardless of wear. This also applies to the
spare wheel.
Vehicles with tire pressure monitor: the
spare wheel is not equipped with a sensor for
monitoring tire pressure. If you have installed
a spare wheel, the tire pressure monitor will
not function for this wheel. The system may
continue to show the tire pressure of the
wheel that has been removed for a few
minutes. The value displayed for the position
where the spare wheel is installed is not the
same as the current tire pressure of the spare
wheel.
When you are driving with the spare wheel
mounted, the tire pressure monitor cannot
function reliably. Only restart the tire pressure
monitor when the defective wheel has been
replaced with a new wheel and sensor.
More Information can be found under "Tire
pressure monitor" (Y page 285). 302
