Mounting a new wheel
G
WARNING
Oiled or greased wheel bolts or damaged
wheel bolts/hub threads can cause the
wheel bolts to come loose. As a result, you
could lose a wheel while driving. There is a
risk of accident.
Never oil or grease wheel bolts. In the event
of damage to the threads, contact a quali-
fied specialist workshop immediately. Have
the damaged wheel bolts or hub threads
replaced/renewed. Do not continue driving. G
WARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is a risk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
Always observe the instructions and safety
notes on "Changing a wheel"
(Y page 297).
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been
approved for Mercedes-Benz vehicles and the
respective wheel.
! On vehicles equipped with a tire pressure
monitor, electronic components are located
in the wheel.
Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed at a qualified spe-
cialist workshop. X
Clean the wheel and wheel hub contact sur-
faces.
X Slide the new wheel onto the wheel hub and
push it on.
X Screw in the wheel bolts and tighten them
lightly.
Lowering the vehicle G
WARNING
The wheels could come loose if the wheel
bolts or wheel nuts are not tightened to the
prescribed tightening torque. There is a risk
of an accident.
Ensure that the wheel bolts or wheel nuts
are tightened to the prescribed tightening
torque.
If you are not sure, do not move the vehicle.
Contact a qualified specialist workshop and
have the tightening torque checked immedi-
ately. :—A
Wheel bolts
X Place the adapter and the ratchet on the
hexagon head nut of the jack such that the
lettering AB/DOWN is visible.
X Turn the ratchet in the AB/DOWN direction
until the vehicle is once again standing
firmly on the ground.
X Put the jack aside.
X Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indicated (:
to A).
Tighten the wheel bolts to the following
tightening torques:
R Steel wheel 147 lb-ft (200 Nm)
R Alloy wheel 133 lb-ft (180 Nm)300

X
Turn the jack back to its out-of-use position.
X Stow the jack and the rest of the tire-
change tool kit in the vehicle again.
X Wheel with hub cap: position the opening
for the tire valve in the hub cap over the tire
valve.
X Push the edge of the hub cap with both
hands against the wheel until it clicks into
place. Make sure the hub cap retaining
catches engage on the steel wheel.
X If included in the vehicle equipment, secure
the faulty wheel in the spare wheel bracket
(Y page
303). Otherwise, transport the
faulty wheel in the cargo compartment.
X Check the tire pressure of the newly moun-
ted wheel and adjust it if necessary.
Observe the recommended tire pressure
( Y page

282).
Vehicles with the tire pressure monitor sys-
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
