Notes on noise or unusual handling characteris-
tics
Mak
e sure there are no vibrations, noises or
unusual handling characteristics when the vehicle
is in motion. This may indicate that the wheels or
tyres are damaged. Hidden tyre damage could
also be causing the unusual handling characteris-
tics.
If you suspect that a tyre is defective, reduce your
speed immediately and have the tyres and wheels
checked at a qualiNed specialist workshop. Notes on regularly inspecting wheels and tyres
&
WARNING Risk of injur
y due to damaged
tyres
Damaged tyres can cause tyre pressure loss. 
Check the tyres regularly for signs of
damag
e and replace any damaged tyres
immediately. &
WARNING Risk of aq
uaplaning due to
insuPcient tyre tread
*nsuPcient tyr
e tread will result in reduced
tyre grip.
The risk of aquaplaning is increased on wet
roads, especially when the speed of the vehi-
cle is not adapted to suit the conditions. 
Thus, you should regularly check the
tr

ead depth and the condition of the
tread across the entire width of all tyres.
Minimum tread depth for:
= Summer tyr

es: 3 mm
= M+S tyres: 4 mm 
For safety reasons, replace the tyres
bef
ore the legally-prescribed limit for the
minimum tread depth is reached. Carry out the following checks on all wheels regu-
lar
ly, at least once a month or as required, for
example, prior to a long journey or driving oM-
road:
= Check the tyre pressure (  page 413).=
V
isually inspect wheels and tyres for damage.
= Check the valve caps.
= Visual check of the tyre tread depth and the
tyre contact surface across the entire width.
The minimum tread depth for summer tyres is
3 mm and for winter tyres 4 mm. Notes on snow chains
&
WARNING Risk of accident due t
o incor-
rectly Ntted snow chains
If you have Ntt
ed snow chains to the front
wheels, they may drag against the vehicle
body or chassis components. 
Never Nt sno
w chains to the front
wheels. 
Only Nt sno
w chains on the rear wheels
in pairs. 412

NOTE Damag e to components of the vehi-
cle body or chassis due to Ntted snow
chains If you
Nt sno
w chains to the front wheels of
4MATIC vehicles, you may damage compo-
nents of the vehicle body or chassis. 
Only Nt sno
w chains to the rear wheels
of 4MATIC vehicles. Observe the following notes when using snow
c

hains:
= Snow chains are only permissible for certain
wheel/tyre combinations. You can obtain
information about this from a Mercedes-Benz
Service Centre.
= 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 Ntted, the maximum per-
missible speed is 50 km/h. =
V
ehicles with Active Parking Assist: do not use
Active Parking Assist when snow chains are
Ntted.
% You can permanently limit the maximum
speed f

or driving with winter tyres
(  page 239).
% You can deactivate ESP n
t
o pull away
( page 232). This allows the wheels to spin,
achieving an increased driving force. Tyre pressure
Notes on tyre pressure
&
WARNING Risk of accident due t
o insuP-
cient or excessive tyre pressure
UnderinOated or o
verinOated tyres pose in par-
ticular the following risks:
= The tyres can burst.
= The tyres can wear excessively and/or
unevenly. =
The dr
iving characteristics as well as the
steering and braking characteristics may
be greatly impaired. 
Comply with the recommended tyre
pr

essure and check the tyre pressure of
all tyres, including the spare wheel, regu-
larly:
= mont
hly
= when the load changes
= before embarking on a longer journey
= if operating conditions change, e.g. oM-
road driving 
Adjust the tyre pressure, if necessary. Tyre pressure which is too high or too low can:
= Shor

ten the service life of the tyres.
= Cause increased tyre damage.
= Adversely aMect driving characteristics and
thus driving safety, e.g. due to aquaplaning. Wheels and tyres

&
WARNING Risk of accident due t o repea-
ted pressure drop in the tyres
The wheels, valves or tyres could be damaged.
T
oo low a tyre pressure can lead to the tyres
bursting. 
Examine the tyres for foreign objects. 
Check whether the tyre has a puncture
or t

he valve has a leak. 
If you are unable to rectify the damage,
cont

act a qualiNed specialist workshop. Information on the recommended tyre pressure
f

or the vehicle's factory-Ntted tyres can be found
on the tyre pressure table on the inside of the fuel
Nller Oap ( page 414).
Use a suitable pressure gauge to check the tyre
pressure. The outer appearance of a tyre does not
permit any reliable conclusion about the tyre pres-
sure.
Only correct tyre pressures when the tyres are
cold. Conditions for cold tyres:
= The vehicle has been parked with the tyres out
of direct sunlight for at least three hours. =
The v
ehicle has travelled less than 1.6 km.
The vehicle's tyres heat up when driving. As the
temperature of the tyres increases, so too does
the tyre pressure.
Vehicles with a tyre pressure monitoring system:
you can also see the tyre pressure in the driver's
display ( page 415).
Notes on trailer operation
Always inOate the rear axle tyres to the recom-
mended tyre pressures on the tyre pressure table
for increased load. Tyre pressure table
The tyre pressure table is on the inside of the fuel
Nller Oap. The tyre pressure table shows the recommended
tyr

e pressure for all tyres approved for this vehi-
cle. The recommended tyre pressures apply for
cold tyres under various operating conditions, i.e.
loading and/or speed of the vehicle.
If one or more tyre sizes precede a tyre pressure,
the following tyre pressure information is only
valid for those tyre sizes and their respective load
condition. 414
Wheels and tyres

If the preceding tyre sizes are complemented by
t
he


Compare the current tyre pressure with the
r
ecommended tyre pressure for the current
operating condition ( page 414). Addition-
ally, observe the notes on cold tyres
( page 413).
% The values displayed in the driver's display
ma
y deviate from those of the tyre pressure
gauge as they refer to sea level. At high eleva-
tions, the tyre pressure values indicated by a
tyre pressure gauge are higher than those
shown in the driver's display.

WARNING Risk of injur
y through exceed-
ing the speciNed tyre load-bearing capa-
city or the permissible speed rating
Exceeding the load-bearing capacity of the
tyr
es can lead to tyre damage and could cause
the tyres to explode. 
Therefore, only use tyre types and sizes
appr

oved for your vehicle model. 
Observe the tyre load-bearing capacity
r

ating and speed rating required for your
vehicle. *
NOTE V
ehicle and tyre damage caused by
non-approved tyre types and sizes For safety reasons, only use tyres, wheels and
accessor

ies which have been specially
approved by Mercedes-Benz for your vehicle.
These tyres are specially adapted to the active
safety systems, such as ABS, ESP n
and
4MATIC, and marked as follows:
= MO = Mercedes-Benz Original
= MOE = Mercedes-Benz Original Extended
(run-Oat tyres only for certain wheels)
= MO1 = Mercedes-Benz Original (only cer-
tain AMG tyres)
Otherwise, certain properties, such as han-
dling characteristics, vehicle noise emissions,
consumption, etc. could be adversely aMec-
ted. Furthermore, other tyre sizes could result
in the tyres rubbing against the body and axle
components when loaded. This could result in
damage to the tyre or the vehicle. Only use tyres, wheels and accessories that
ha

ve been checked and recommended by
Mercedes-Benz. *
NOTE Risk t
o driving safety from retrea-
ded tyres Retreaded tyres are neither tested nor recom-
mended b

y Mercedes-Benz, since previous
damage cannot always be detected on retrea-
ded tyres.
For this reason driving safety cannot be guar-
anteed. 
Do not use used tyres if you have no
inf
ormation about their previous usage. *
NOTE P
ossible wheel and tyre damage
when driving over obstacles Large wheels have a smaller section width. As
t

he section width decreases, the risk of
wheels and tyres being damaged when driving
over obstacles increases. Wheels and tyres
