Turn on ESP®and adapt your driving style
accordingly. When the outside temperature
falls below 10 †, use M+S tires.
iDifferent driving styles may lead to high tire
wear and the tires may reach the minimum
tire tread depth after only ashort time.
Regular checking of wheels and tires
GWARNING
Damaged tires can cause tire inflation pres-
sure loss. As aresult, you could lose control of
your vehicle. There is arisk 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
am onth. Check wheels and tires after driving
off-road or on rough roads. Damaged wheels
can cause aloss of tire pressure. Pay particular
attention to damage such as:
Rcuts in the tires
Rpunctures
Rtears in the tires
Rbulges on tires
Rdeformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tread across the whole width of
the tire (
Ypage 317). If necessary, turn the
front wheels to full lock in order to inspect the
inner side of the tire surface.
All wheels must have avalve cap to protec tthe
valve against dirt and moisture. Do not mount
anything ontot he 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 (
Ypage 319).
The service life of tires depends, among other
things, on the following factors:
Rdriving style
Rtire pressure
Rdistance covered
Notes on tire tread
GWARNING
Insufficient tire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where speed is not adapted to suit the driving con-
ditions. There is arisk of accident.
If the tire pressure is too high or too low, tires
may exhibit different levels of wear at differ-
ent locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for:
RSummer tires: âin (3 mm)
RM+S tires: ãin (4 mm)
For safety reasons, replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached.
Marking :shows 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 atread depth of approx-
imately áin (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
ROnly mount tires and wheels of the same type
and make.

and do not provid esufficient traction. There is
ar isk of an accident.
M+S tires with atread depth of less than ãin
(4 mm) must be replaced immediately.
At temperatures belo w45‡ (+7 †), use winter
tires or all-season tires. Bot htype soft ire are
identified by the M+S marking.
Only winter tires bearing the isnowflake
symbol in addition to the M+S marking provide
the best possibl egrip in wintry road conditions.
Only these tires wil lallow driving safety systems
such as ABS and ESP
®to function optimally in

Snow chains
GWARNING
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 arisk of an accident.
To avoid hazardous situations:
Rnever install snow chains to the front
wheels
Ralways install snow chains in pairs to the
rear wheels.
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 acorresponding
standard of quality. For more information,
please contact aqualified specialist workshop.
If you inten dtomount snow chains, please bear
the following points in mind:
RSnow chains may not be mounted on all
wheel/tire combinations .Permissible wheel-
tire combination s(
Ypage 340).
ROnly use snow chains when driving on roads
completely covered by snow. Remove the
snow chains as soon as possible when you
come toaroad that is not snow-covered.
RLocal regulations may restrict the use of snow
chains. Observe the appropriate regulations if
you wish to mount snow chains.
RDo not exceed the maximum permissible
speed of 31 mph (50 km/h).
ROn vehicles with AIRMATIC, you must drive at
raised vehicle level if snow chains have been
installed (
Ypage 172).
RWhen snow chains are installed, never use
Active Parking Assist (Ypage 177).
You may wish to deactivate ESP®when pulling
away with snow chains installed:
RAll vehicles (except Mercedes ‑AMG vehicles)
(Ypage 67)
RMercedes‑AM Gvehicles (Ypage 68)
You can thereby allow the wheels to spin in a
controlled manner, achieving an increased driv- ing force (cuttin gaction).

Important safety notes
GWARNING
Underinflated or overinflated tires pose the
following risks:
Rthe tires may burst, especially as the load
and vehicle speed increase.
Rthe tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
Rthe driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is arisk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel:
Rmonthly, at least
Rif the load changes
Rbefore beginning along journey
Runder different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.

Important safety notes
Observe the notes on tire pressure
(Ypage 319).
Information on air pressure for the tires on your
vehicle can be found:
Ron the vehicle's Tire and Loading Information
placard on the B-pillar
Rin the tire pressure table in the fuel filler flap
(Ypage 150)
Rin the "Tire pressure" section
Checking tire pressures manually
To determine and set the correct tire pressure,
proceed as follows:
XRemove the valve cap of the tire that is to be
checked.
XPress the tire pressure gauge securely onto
the valve.
XRead the tire pressure and compare it to the
recommended value on the Tire and Loading
Information placard or the tire pressure table (
Ypage 319).
XIf the tire pressure is too low, increase the tire
pressure to the recommended value.
XIf the tire pressure is too high, release air. To
do so, press down the metal pin in the valve,
using the tip of apen for example. Then check
the tire pressure againu sing the tire pressure
checker.
XScrew the valve cap onto the valve.
XRepeatt hese steps for the other tires.
Tire pressure loss warning system
General notes
While the vehicle is in motion, the tire pressure
loss warning system monitors the set tire pres-
sure using the rotational speed of the wheels.
This enables the system to detect significant
pressure loss in atire. If the speed of rotation of
aw heel changes as aresult of aloss of pressure,
ac orresponding warning message will appeari n
the multifunction display.
You can recognize the tire pressure loss warning
by the Run Flat Indicator Active
Press'OK' to Restartmessage which appears in
the Servicemenu of the multifunction display.
Information on the message displayc an be
found in the "Restarting the tire pressure loss
warning system" section (
Ypage 323).
Important safety notes
The tire pressure warning system does not warn you of an incorrectly set tire pressure. Observe
the notes on the recommended tire pressure
(
Ypage 319).
The tire pressure loss warning does not replace

Important safety notes
GWARNING
Each tire, including the spare (if provided),
shoul dbec hecked at least once every two
weeks when cold and inflated to the pressure recommended by the vehicle manufacturer
on the Tire and Loading Information placard
on the driver's door B-pillaro rthe tire pres-
sure label on the inside of the fuel fillerf lap. If
you rvehicle has tires of adifferent size than
the size indicated on the Tire and Loading
Information placard or, if available, the tire
pressure label, you shoul ddetermine the
proper tire pressure for those tires.
As an adde dsafety feature, you rvehicle has
been equipped with atire pressure monitoring
system (TPMS) that illuminates alow tire pres-
sure telltal ewhen one or more of you rtires
are significantly underinflated. Accordingly,
when the low tire pressure telltal elights up,
you shoul dstop and check you rtires as soon
as possible, and inflate them to the proper
pressure. Driving on asignificantly underin-
flated tire cause sthe tire to overheata nd can
leadtot ire failure.
Underinflation also reduces fuel efficiency
and tire tread life, and may affect the vehicle's
handling and stopping ability. Please note that the TPMS is not asubstitute for proper tire
maintenance, and it is the driver's responsi-
bility to maintain correct tire pressure, even if
underinflation has not reached the level to
trigger illuminatio nofthe TPMS low tire pres-
sure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the sys-
tem detects amalfunction, the warning lamp
wil lflash for approximately aminute and then
remain continuously illuminated .This
sequence wil lberepeated every time the vehi-
cle is started as long as the malfunction
exists. When the malfunction indicator is illu-
minated, the system may not be abl etodetect
or signal low tire pressure as intended.
TPMS malfunctions may occur for avariety of
reasons, including the installation of incom-
patibl ereplacement or alternate tires or
wheel sonthe vehicle that prevent the TPMS
from functioning properly. Alway scheck the
TPMS malfunction telltal eafter replacing one
or more tires or wheel sonyourv ehicle to
ensure that the replacement or alternate Tires
and wheelsa llow the TPMS to continue to
function properly.
It is the driver's responsibility to set the tire
pressure to that recommended for cold tires
which is suitable for the operating situation
(
Ypage 319). Note that the correct tire pressure
for the current operating situation must first be
taught-in to the tire pressure monitor. If there is
as ubstantial loss of pressure, the warning
threshold for the warning messag eisaligned to
the reference values taught-in. Restart the tire
pressure monitor after adjusting the pressure of
the cold tires (
Ypage 325). The current pres-
sures are saved as new reference values. As a
result, awarning messag ewillappear if the tire
pressure drops significantly.
The tire pressure monitor does not warn you of
an incorrectly set tire pressure. Observe the
notes on the recommended tire pressure
(
Ypage 319).
The tire pressure monitor is not abl etowarn you
of as udden loss of pressure, e.g. if the tire is
penetrated by aforeign object. In the event of a
su

dden loss of pressure, bring the vehicle to a
halt by braking carefully. Avoid abrupt steering
movements.
