Important safety notes
G
WARNING
If you install wheels and tires with incorrect
dimensions, the service brake or wheel sus-
pension components may be damaged. There is a risk of an accident.
Always replace wheels and tires with ones
that comply with the specifications of the
original part.
When replacing wheels, pay attention to the:
R Designation
R Model
When replacing tires, pay attention to the:
R Designation
R Manufacturer
R Model G
WARNING
A flat tire will severely affect the driving char- acteristics as well as the steering and braking
of the vehicle. There is a risk of an accident.
Tires without run-flat characteristics:
R Do not drive on with a flat tire.
R Change the flat tire immediately with an
emergency spare wheel or spare wheel.
Alternatively, consult a qualified specialist
workshop.
Tires with run-flat characteristics:
R Observe the information and warning notes
on MOExtended tires (run-flat tires).
Accessories that are not approved for your vehi-
cle by Mercedes-Benz or are not being used cor- rectly can impair the operating safety.
Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and inquire about:
R suitability
R legal stipulations
R factory recommendations
Further information regarding wheels and tires
can be found under "Wheel/tire combinations"
(Y page 377). You can ask for information regarding permitted
wheel/tire combinations at an authorized
Mercedes-Benz Center.
Tire pressure information can be found:
R on the Tire and Loading Information placard
on the B-pillar on the driver's side
R in the tire pressure table in the fuel filler flap
R in the "Tire pressure" section Operation
Information on driving
Check the tire pressure when the vehicle is
heavily laden and adjust prior to a trip.
While driving, pay attention to vibrations, noises and unusual handling characteristics, e.g. pull-
ing to one side. This may indicate that the
wheels or tires are damaged. If you suspect that
a tire is defective, reduce your speed immedi-
ately. Stop the vehicle as soon as possible to
check the wheels and tires for damage. Hidden tire damage could also be causing the unusual
handling characteristics. If you find no signs of
damage, have the tires and wheels checked at a
qualified specialist workshop.
When parking your vehicle, make sure that the
tires do not get deformed by the curb or other
obstacles. If it is necessary to drive over curbs,
speed humps or similar elevations, try to do so
slowly and at an obtuse angle. Otherwise, the
tires, particularly the sidewalls, may be dam-
aged. Regular checking of wheels and tires
G
WARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control of your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
Check wheels and tires for damage at least once a month. Check wheels and tires after driving
off-road or on rough roads. Damaged wheels
can cause a loss of tire pressure.
Pay particular attention to damage such as:
R cuts in the tires
R punctures in the tires 352
OperationWheels and ti
res

R
tears in the tires
R bulges on tires
R deformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tread across the whole width of
all tires (Y page 353). If necessary, turn the
front wheels to full lock in order to inspect the
inner side of the tire surface.
All wheels must have a valve cap to protect the
valve against dirt and moisture. Do not mount
anything onto the valve other than the standard valve cap or other valve caps approved by
Mercedes-Benz for your vehicle. Do not use any other valve caps or systems, e.g. tire pressure
monitoring systems.
Regularly check the pressure of all the tires par- ticularly prior to long trips. Adjust the tire pres-
sure as necessary (Y page 355).
Observe the notes on the emergency spare
wheel (Y page 378).
The service life of tires depends, among other
things, on the following factors:
R Driving style
R Tire pressure
R Distance covered Notes on tire tread
G
WARNING
If there is insufficient tire tread, the tire trac-
tion decreases. The tire tread is no longer able to dissipate water. This increases the risk of
hydroplaning when the road surface is wet,
particularly when the vehicle's speed is not
adapted to the road conditions. There is a risk
of an accident.
When the tire pressure is too high or too low,
tires may wear differently at different points
on the tire tread. Therefore, regularly check
the tire tread depth and the condition of the
tread across the whole width of all tires.
Minimum tire tread depth on:
R Summer tires: 00CEin (3 mm)
R M+S tires: 00CFin (4 mm)
For safety reasons, have the tires replaced
before they reach the legally prescribed min-
imum tire tread depth. Marking
0043shows where the bar indicator
(arrow) for tread wear is integrated into the tire
tread.
Treadwear indicators (TWI) are required by law. Six indicators are positioned on the tire tread.
They are visible once a tread depth of approx-
imately 00CDin (1.6 mm) has been reached. If this
is the case, the tire is so worn that it must be
replaced. Selecting, mounting and replacing
tires
R Only mount tires and wheels of the same type
and make.
Exception: it is permissible to mount a differ-
ent type or make in the event of a flat tire.
Observe here the "MOExtended tires (tires
with run-flat characteristics)" section
(Y page 336).
R Only mount tires of the correct size onto the
wheels.
R Break in new tires at moderate speeds for the
first 60 miles (100 km). The new tires only
reach their full performance after this dis-
tance.
R Do not drive with tires which have too little
tread depth. This significantly reduces the
traction on wet roads (hydroplaning).
R Replace the tires after six years at the latest,
regardless of wear.
Observe the notes on the emergency spare
wheel (Y page 378). MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flat char- acteristics), you can continue to drive your vehi- Operation
353Wheels and tires Z

cle even if there is a total loss of pressure in one
or more tires.
MOExtended tires may only be used in conjunc-
tion with an active tire pressure loss warning
system or with an active tire pressure monitor
and on wheels specifically tested by Mercedes- Benz.
Notes on driving with MOExtended tires with a
flat tire (Y page 336).
i Vehicles equipped with MOExtended tires
are not equipped with a TIREFIT kit at the fac- tory. It is therefore recommended that you
additionally equip your vehicle with a TIREFIT
kit if you mount tires that do not feature run- flat characteristics, e.g. winter tires. A TIREFIT
kit may be obtained from a qualified specialist
workshop. Winter operation
General notes
Have your vehicle winter-proofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 372). Driving with summer tires
At temperatures below 45 ‡ (+7 †), the elas-
ticity of summer tires and therefore also the
traction and braking capability are reduced con-
siderably. Change the tires on your vehicle to
M+S tire s. Using su mmer tires at very cold tem-
peratures could cause cracks to form, thereby
damaging the tires permanently. Mercedes-
Benz cannot accept responsibility for this type
of damage. G
WARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control of your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately. M+S tires
G
WARNING
M+S tires with a tire tread depth of less than
00CF in (4 mm) are not suitable for use in winter
and do not provide sufficient traction. There is
a risk of an accident.
M+S tires with a tread depth of less than 00CFin
(4 mm) must be replaced immediately.
At temperatures below 45 ‡(+7 †), use winter
tires or all-season tires. Both types of tire are
identified by the M+S marking.
Only winter tires bearing the 004Dsnowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road conditions.
Only these tires will allow driving safety systems
such as ABS and ESP ®
to function optimally in
winter. These tires have been developed specif-
ically for driving in snow.
Use M+S tires of the same make and tread on all wheels to maintain safe handling characteris-
tics.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
Once the winter tires are mounted:
X Check the tire pressures (Y page 358).
X Restart the tire pressure monitor
(Y page 359).
X Vehicles for Canada: restart the tire pres-
sure loss warning system (Y page 359).
Information about driving with an emergency
spare wheel (Y page 378). Snow chains
G
WARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is a risk of an accident. 354
Winter operationWheels and tires

To avoid hazardous situations:
R never install snow chains to the front
wheels
R always install snow chains in pairs to the
rear wheels.
! Check the snow chains for damage before
mounting them. Damaged or worn snow
chains may snap and damage the following
components:
R wheel
R wheel housing
R wheel suspension
For this reason, you must use only snow
chains that are free of defects. Observe the
manufacturer's mounting instructions.
! You must drive at raised vehicle level (height
1) if snow chains have been installed. The
vehicle may otherwise be damaged.
! Vehicles with ADS (Adaptive Damping
System): do not use the sport mode when
driving with snow chains mounted. The vehi-
cle may otherwise be damaged.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that have been specially approved for your vehicle by
Mercedes-Benz, or are of a corresponding
standard of quality. For more information,
please contact a qualified specialist workshop.
Install the snow chains on all driven wheels for
maximum tractive power and driving stability. If
you own snow chains for two driven wheels only, install the snow chains to the wheels on the rear
axle. The vehicle then remains more stable
under braking.
If you intend to mount snow chains, please bear
the following points in mind:
R Snow chains may not be mounted on all
wheel/tire combinations. Permissible
wheel/tire combinations (Y page 377).
R Only use snow chains when driving on roads
completely covered by snow. Remove the
snow chains as soon as possible when you
come to a road that is not snow-covered.
R Local regulations may restrict the use of snow
chains. Observe the appropriate regulations if
you wish to mount snow chains. R
Do not exceed the maximum permissible
speed of 30 mph (50 km/h).
R When snow chains are installed, never use
Active Parking Assist (Y page 192) or the
Parking Package with rear view camera.
You may wish to deactivate ESP ®
(Y page 71)
when pulling away with snow chains mounted.
You can thereby allow the wheels to spin in a
controlled manner, achieving an increased driv-
ing force (cutting action).

Important safety notes G
WARNING
Underinflated or overinflated tires pose the
following risks:
R the tires may burst, especially as the load
and vehicle speed increase.
R the tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
R the driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is a risk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel:
R monthly, at least
R if the load changes
R before beginning a long journey
R under different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
Details on tire pressure can be found at the fol-
lowing positions in the vehicle:

placard and tire pressure table shown here are
examples. Tire pressure specifications are vehi- cle-specific and may deviate from the data
shown here. The tire pressure specifications
that are valid for your vehicle can be found on
the Tire and Loading Information placard and
tire pressure table on the vehicle.
General notes The recommended tire pressures for the tires
mounted at the factory can be found on the
labels described here.
Operation with emergency spare wheel:
information on operation with the emergency
spare wheel can be found under "Emergency
spare wheel" (Y page 378).
Operation with a trailer: the applicable value
for the rear axle is the maximum tire pressure
value stated in the table inside the fuel filler flap.
Further information on tire pressures can be
obtained at a qualified specialist workshop.
Tire and Loading Information placard Recommended tire pressures
The Tire and Loading Information placard is on
the B-pillar on the driver's side (Y page 362).
The Tire and Loading Information placard con-
tains the recommended tire pressures for cold
tires. The recommended tire pressures are valid for the maximum permissible load and up to the
maximum permissible vehicle speed. Tire pressure table The tire pressure table is on the inside of the fuel
filler flap. It shows the tire pressure for all tires
permitted at the factory for this vehicle; see
illustration (example). The tire pressure table contains the recommen-
ded pressures for cold tires for various operat-
ing conditions, i.e. differing load and speed con-
ditions.
If a tire size precedes a tire pressure, the fol-
lowing tire pressure information is only valid for that tire size; see illustration (example). The load conditions "partially laden" and "fully
laden" are defined in the table for different num- bers of occupants and amounts of luggage. The
actual number of seats may differ. 356
