The recommended tire inflation pressures
for your vehicle can be found on
Rthe Tire and Loading Information placard
located on the driver’s door B-pillar
(Y page 236)
R the tire inflation pressure label on the
inside of the fuel filler flap
The tire inflation pressures are not listed in
the Operator’s Manual. G
Warning!
The tire pressure loss warning system does
not
provide a warning for wrongly selected tire
inflation pressures. Always adjust tire
inflation pressure according to the Tire and
Loading Information placard on the driver’s
door B-pillar or on the tire inflation pressure
label located on the inside of the fuel filler flap.
The tire pressure loss warning system does
not replace regular checks of the tire inflation
pressures since a gradual pressure loss in
more than one tire cannot be detected by the
tire pressure loss warning system.
The tire pressure loss warning system is not
able to issue a warning due to a sudden
dramatic loss of tire inflation pressure (e.g.
tire blowout caused by a foreign object). In
this case bring the vehicle to a halt by carefully
applying the brakes and avoiding abrupt
steering maneuvers.
Restarting the tire pressure loss warning
system
The tire pressure loss warning system must
be restarted in the following situations:
R after you have changed the tire inflation
pressure
R after you have replaced the wheels or tires
R after you have installed new wheels or tires
X Using the Tire and Loading Information
placard on the driver’s door

B-pillar or, if
available, the tire inflation pressure label on
the inside of the fuel filler flap, make sure
the tire inflation pressure of all four tires is
correct. G
Warning!
The tire pressure loss warning system can
only
warn you in a reliable manner if you have
set the correct tire inflation pressures for
each tire.
If an incorrect tire inflation pressure was set,
the system will monitor the pressure
according to the incorrect value.
X Switch on the ignition.
X Make sure the standard display appears in
the multifunction display

(Y page 126).
X Press button * or & on the
multifunction steering wheel repeatedly
until the following message appears in the
multifunction display:
Run Flat Indicator
Active
Menu: R-Button
X Press the reset button (Y page 122).
The following message will appear in the
multifunction display:
Restart
Run Flat Indicator?
X If you wish to confirm: Press button
W.
The following message will appear in the
multifunction display:

After a certain “learning phase”, the tire
pressure loss warning system checks the
set pressure values for all four tires.
X If you wish to cancel:
Press button X.
Advanced Tire Pressure Monitoring
System (Advanced TPMS), (USA only) Your vehicle is equipped with the Advanced
Tire Pressure Monitoring System (Advanced
TPMS).

It measures the tire inflation pressure
in the vehicle’s tires and issues warnings in
case of pressure loss in one or more of the
tires. 232

The respective tire is indicated by a red
rectangle.
Restarting Advanced TPMS
G
Warning!
It is the driver’s responsibility to set the tire
inflation pressure to the recommended cold
tire inflation pressure. Underinflated tires
affect
the ability to steer or brake the vehicle.
You might lose control over the vehicle.
When you restart the TPMS, the system sets
new reference values for each tire.
The TPMS must be restarted when you have
adjusted the tire inflation pressure to a new
level (e.g. because of different load or driving
conditions). The TPMS is then recalibrated to
the current tire inflation pressures.
Restart the TPMS after adjusting the tire
inflation pressure to the inflation pressure
recommended for the vehicle operating
condition. Tire pressure should only be
adjusted on cold tires. Observe the
recommended tire inflation pressure on the
Tire and Loading Information placard on the
driver’s door B-pillar. Some vehicles may have
supplemental tire pressure information for
driving at high speeds or for vehicle loads less
than the maximum loaded vehicle condition.
If such information is provided, it can be
found on the inside of the fuel filler flap.
X Using the Tire and Loading Information
placard on the driver’s door

B-pillar
(Y page 236) or the supplemental tire
inflation pressure information on the inside
of the fuel filler flap, make sure the tire
inflation pressure of all four tires is correct.
X Switch on the ignition.
X Press button V or U on the
multifunction steering wheel repeatedly
until the standard display appears in the
multifunction display

(Y page 126).
X Press button &
or * repeatedly until
you see the current inflation pressures for
each tire appear in the display or the
following message appears in the
multifunction display: Tire pressure
displayed after
driving for
a few minutes.
X Press the reset button (Y page 122).
The following message will appear in the
multifunction display:
Restart tire
pressure monitor?
X If you wish to confirm: Press button
W.
The following message will appear in the
multifunction display:
Tire Pressure Monitor
Restarted
After driving a few minutes the system
verifies that the current tire inflation
pressures

are within the system’s specified
range. Afterwards the current tire inflation
pressures are accepted as reference values
and then monitored.
X If you wish to cancel:
Press button X.
i When the wheel positions have been
changed, the inflation pressure of a tire
may be displayed for the wrong position
temporarily.

After driving for a few minutes,
the inflation pressure will be shown for the
correct position. Maximum tire inflation pressure
G
Warning!
Never exceed the maximum tire inflation
pressure. Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are
more likely to fail from being overheated.
Do

not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout)
because they are more likely to become Tires and wheels
