X Before restarting, make sure that the tire
pressures are set properly on all four tires
for the respective operating conditions.
The recommende dtire pressures can be
found on the Tire and Loading Information
placard on the B-pillar on the driver's side
or the tire pressure table on the fuel filler
flap .The tire pressure loss warning system
can only give reliablew arnings if you have
set the correct tire pressure. If an incorrect
tire pressure is set, these incorrectv alues
will be monitored.

General notes If
at ire pressure monitor is installed, the
vehicle's wheels have sensors that monitor
the tire pressures in all four tires. The tire
pressure monitor warns you if the pressure
drops in one or more of the tires. The tire
pressure monitor only functions if the correct
sensors are installed on all wheels.
Information on tire pressures is displayed in
the multifunction display. After afew minutes
of driving, the current tire pressure of each
tire is shown in the Service menu of the
multifunction display. For further information
on displaying this message, refer to the
"Checking the tire pressure electronically"
section (Y page 344). 342

The tire pressure monitor has
ayellow
warning lamp in the instrument cluster for
indicatin gapressure loss or malfunction.
Whether the warning lamp flashes or lights up
indicates whether atire pressure is too low or
the tire pressure monitor is malfunctioning:
R if the warning lamp is lit continuously, the
tire pressure on one or more tires is
significantly too low. The tire pressure
monitor is not malfunctioning.
R if the warning lamp flashes for around a
minute and then remains lit constantly, the
tire pressure monitor is malfunctioning.
If the tire pressure monitor is malfunctioning,
it may take more than ten minutes for the tire
pressure warning lamp to inform you of the
malfunction by flashing for approximately one
minute and then remaining lit. When the
malfunction has been rectified, the tire
pressure warning lamp goes out after afew
minutes of driving.
The tire pressure values indicated by the on-
board computer may differ from those
measured at agas station with apressure
gauge. The tire pressures shown by the on-
board computer refer to those measured at
sea level. At high altitudes, the tire pressure
values indicated by apressure gauge are
higher than those shown by the on-board
computer .Inthis case, do not reduce the tire
pressures.
The operation of the tire pressure monitor can
be affected by interference from radio
transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.
Checking the tire pressure
electronically X
Make sure that the SmartKey is in position
2(Y page 147) in the ignition lock .
X Press the 000Aor0004 button on the
steering wheel to select the Serv. menu.X
Press the 0006or0005 button to select
Tire Pressure .
X Press the 000Cbutton.
The current tire pressure of each tire is
shown in the multifunction display.
If the vehicle was parked for longer than
20 minutes ,the Tire pressures will be
displayed after driving
afew minutes message is shown.
After ateach-in process, the tire pressure
monitor automatically detects new wheels or
new sensors. As long as aclear allocation of
the tire pressure value to the individual
wheels is not possible, the Tire Pressure Monitor Active displaym
essage is shown
instead of the tire pressure display. The tire
pressures are already being monitored.
i If an emergency spare wheel is mounted,
the system may continue to show the tire
pressure of the wheel that has been
removed for afew minutes. If this occurs,
note that the value displayed for the
position where the spare wheel is mounted
is not the same as the current tire pressure
of the emergency spare wheel.
Tire pressurem onitor warning
messages If the tire pressure monitor detects
apressure
loss in one or more tires, awarning message
is shown in the multifunction displaya nd the
yellow tire pressure monitor warning lamp
comes on.
R If the Correct Tire Pressure message
appears in the multifunction display, the
tire pressure in at least one tire is too low
and must be corrected at the next
opportunity.
R If the Check Tire Pressure message
appears in the multifunction display, the
tire pressure in one or more tires has
dropped significantly and the tires must be
checked.

ombinationsGeneral notes
! For safety reasons, Mercedes-Benz
recommends that you only use tires and
wheels which have been approved by
Mercedes-Benz specifically for your
vehicle.
These tires have been specially adapted for
use with the control systems, such as ABS
or ESP ®
,a nd are marked as follows:
R MO =Mercedes-BenzO riginal
R MOE =Mercedes-BenzO riginal Extended
(tires featuring run-flat characteristics)
R MO1 =Mercedes-Benz Original (only
certain AMG tires)
Mercedes-BenzO riginal Extended tires
may only be usedonw heels that have been
specifically approved by Mercedes-Benz.
Only use tires, wheels or accessories
tested and approved by Mercedes-Benz.
Certain characteristics, e.g. handling,
vehicl enoise emissions or fuel
consumption, may otherwise be adversely
affected. In addition, when driving with a
load, tire dimension variations coul dcause
the tires to come into contact with the
bodywork and axle components. This could
result in damage to the tires or the vehicle.
Mercedes-Benz accepts no liability for
damage resulting from the use of tires,
wheels or accessories other than those
tested and approved. Information on tires, wheels and approved
combinations can be obtained from any
qualified specialist workshop.
Overvie wofabbreviations usedint he
following tire tables:
R BA: both axles
R FA: front axle
R RA: rear axle
The recommended pressures for various
operating conditionsc an be found:
R on the Tire and Loading Information placard
with the recommended tire pressures on
the B-pillar on the driver's side
R in the tire pressure table on the inside of
the fuel filler flap
Observe the notes on recommended tire
pressures under various operating conditions
(Y page 338).
Check tire pressures regularly,a nd only when
the tires are cold. Comply with the
maintenancer ecommendations of the tire
manufacturer in the vehicle document wallet.
Notes on the vehicle equipment –always
equip the vehicle with:
R tires of the same size on agiven axle (left/
right)
R the same type of tires at agiven time
(summer tires, winter tires, MOExtended
tires)
Vehicles with MOExtende dtires are not
equipped with aTIREFIT kit at the factory. It
is therefore recommende dthat you
additionally equip your vehicle with aTIREFIT
kit if you moun ttires that do not feature run-
flat properties ,e.g. winter tires. ATIREFIT kit
may be obtained from aqualified specialist
workshop.
i Not all wheela nd tire combinations are
available at the factory for all countries.
