Notes on noise or unusual handling characteris-tics
Make sure there are no vibrations, noises or unusual handling characteristics when the vehicle
is in motion. This may indicate that the wheels or
tires are damaged. Hidden tire damage could also
be causing the unusual handling characteristics.
If you suspect that a tire is defective, reduce yourspeed immediately and have the tires and wheels
checked at a qualiNed specialist workshop.
Notes on regularly inspecting wheels and tires
&WARNING Risk of injury through damaged
tires
Damaged tires can cause tire pressure loss.
Check the tires regularly for signs of
damage and replace any damaged tires immediately.&WARNING Risk of hydroplaning due to
insuPcient tire tread
*nsuPcient tire tread will result in reduced tire
grip.
In heavy rain or slush the risk of hydroplaning is increased, in particular where speed is not
adapted to suit the conditions.
Thus, you should regularly check the
tread depth and the condition of the
tread across the entire width of all tires.
Minimum tread depth for:
= Summer tires:

Notes on snow chains&WARNING Risk of accident due to incor-
rectly installed snow chains
If you have installed snow chains on the front wheels, they may drag against the vehicle
body or chassis components.
Never install snow chains on the front
wheels.Only install snow chains on the rear
wheels in pairs.*NOTE Damage to components of the vehi-
cle body or chassis due to mounted snow
chains
If you mount snow chains to the front wheels
of 4MATIC vehicles, you may damage compo-
nents of the vehicle body or chassis.
Only mount snow chains to the rear
wheels of 4MATIC vehicles.Observe the following notes when using snow
chains:
= Snow chains are only permissible for certain
wheel/tire combinations. You can obtain infor-
mation about this from a authorized
Mercedes-Benz Service Center.
= For safety reasons, only use snow chains that
have been speciNcally approved for your vehi-
cle by Mercedes-Benz, or snow chains with the same quality standard.
= Comply with the installation instructions of the
snow chain manufacturer.
= If snow chains are installed, the maximum per-
missible speed is 30 mph (50 km/h).
= Vehicles with Active Parking Assist: do not use
Active Parking Assist when snow chains are
installed.
= Vehicles with level control: if snow chains are
installed, only drive at raised vehicle level
(  page 206).\bYou can deactivate ESP n
to pull away
(  page 175). This allows the wheels to spin,
achieving an increased driving force.Tire pressure
Notes on tire pressure
&WARNING Risk of accident due to insuP-
cient or excessive tire pressure
UnderinOated or overinOated tires pose in par-
ticular the following risks:
= The tires can burst.
= The tires can wear excessively and/or
unevenly.
= The driving characteristics as well as the
steering and braking characteristics may
be greatly impaired.
Comply with the recommended tire pres-
sures and check the tire pressure of all
tires, including the spare wheel, regu-
larly:
= Monthly
= When the load changes
= Before embarking on a longer journey
Wheels and tires315

=If operating conditions change, e.g. oM-
road drivingAdjust the tire pressure, if necessary.
Tire pressure which is too high or too low can:
= Shorten the service life of the tires.
= Cause increased tire damage.
= Adversely aMect driving characteristics and
thus driving safety, e.g. due to hydroplaning.
&WARNING Risk of accident due to too low
a tire pressure
Tires with pressure that is too low can over-
heat and burst as a consequence.
In addition, they also suMer from irregular
wear, which can signiNcantly impair the brak-
ing properties and the handling characteris-
tics.
Avoid excessively low tire pressure.
Tire pressure which is too low can cause:
= Tire defects as a result of overheating
=Impaired handling characteristics
= Irregular wear
= Increased fuel consumption&WARNING Risk of accident due to too high
a tire pressure
Tires with excessively high pressure can burst.
In addition, they also suMer from irregular
wear, which can signiNcantly impair the brak-
ing properties and the handling characteris-
tics.
Avoid excessively high tire pressures.
Tire pressure which is too high can cause:
= Increased braking distance
= Impaired handling characteristics
= Irregular wear
= Impaired driving comfort
= Susceptibility to damage
&WARNING Risk of accident due to repea-
ted pressure drop in the tires
The wheels, valves or tires could be damaged.
Too low a tire pressure can lead to the tires
bursting.
Examine the tires for foreign objects.Check whether the tire has a puncture or
the valve has a leak.If you are unable to rectify the damage,
contact a qualiNed specialist workshop.
You can Nnd information on tire pressure for the
vehicle\bs factory-installed tires on the following
labels:
= Tire and loading information placard on the
B!

permit any reliable conclusion about the tire pres-
sure.
Only correct the tire pressure when the tires are
cold. Conditions for cold tires:
= The vehicle has been parked with the tires out
of direct sunlight for at least three hours.
= The vehicle has traveled less than 1 mile
(1.6 km).
The vehicle\bs tires heat up when driving. As the temperature of the tires increases, so too does
the tire pressure.
Vehicles with a tire pressure monitoring system: you can also check the tire pressure using the on- board computer (  page 319).
The tire pressure recommended for increased
load/speed in the tire pressure table can aMect
the ride comfort.&WARNING Risk of accident due to unsuita-
ble accessories on tire valves
If you mount unsuitable accessories onto tire
valves, the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss.Only screw standard valve caps or valve
caps speciNcally approved by Mercedes-
Benz for your vehicle onto the tire valve.
Tire pressure table
The tire pressure table is on the inside of the fuel Nller Oap.
\bThe data shown in the images is example
data.The tire pressure table shows the recommended
tire pressure for all tires approved for this vehicle.
The recommended tire pressures are valid for
cold tires under various operating conditions
according to the load and/or speed of the vehi- cle.
If one or more tire sizes precede a tire pressure,
the following tire pressure information is only valid for those tire sizes and their respective load con-
dition.
The load conditions "partially laden" and "fully
laden" are deNned in the table for diMerent num-
bers of passengers and amounts of luggage. The actual number of seats may diMer from this.Wheels and tires317

Some tire pressure tables only show the rim diam-eter instead of the complete tire size, e.g. R18.
The rim diameter is part of the tire size and can
be found on the tire side wall (  page 329).
= Tire and loading information placard
(  page 322)
= Maximum tire pressure (  page 328)
Checking the tire pressure manuallyRead the tire pressure recommended for the
current operating conditions from the tire and
loading information placard or the tire pres-
sure table. Observe the notes on tire pressure.Remove the valve cap of the tire to be
checked.Press the tire pressure gauge securely onto the valve.Read the tire pressure.If the tire pressure is lower than the recom-
mended value, increase the tire pressure to
the recommended value.If the tire pressure is higher than the recom- mended value, release air. To do so, press
down the metal pin in the valve, e.g. using the
tip of a pen. Then check the tire pressure
again using the tire pressure gauge.Screw the valve cap onto the valve.

Tire pressure monitoring system

qFunction of the tire pressure monitoring system
&DANGER Risk of accident due to incorrect
tire pressure
Each tire, including the spare (if provided),
should be checked monthly when cold and
inOated to the inOation pressure recommen-
ded by the vehicle manufacturer on the vehi-
cle placard or tire inOation pressure label. (If
your vehicle has tires of a diMerent size than
the size indicated on the vehicle placard or
tire inOation pressure label, you should deter-
mine the proper tire inOation pressure for
those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pres-sure telltale when one or more of your tires is
signiNcantly under-inOated. Accordingly, when
