304 Operation
Tires and wheels
Restarting the Run Flat Indicator
The tire inflation pressure monitor must be
restarted in the following situations:

if you have changed the tire inflation
pressure

if you have replaced the wheels or tires

if you have installed new wheels or
tires
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.
Switch on the ignition (page 40).
Make sure the standard display menu
appears in the multifunction display
(
page 149).
Press buttonk orj repeatedly
until the following message appears in
the multifunction display:
Run Flat Indicator
Active
Menu: R-Button
Press the reset button (page 27).
The following message will appear in
the multifunction display:
Restart
Run Flat Indicator?
Warning!G
The Run Flat Indicator does not provide a
warning for wrongly selected tire inflation
pressures. Always adjust tire inflation pres-
sure according to the Tire and Loading
Information placard on the driver’s door
B-pillar (
page 295) or, if available, on the
tire inflation pressure label located on the
inside of the fuel filler flap (
page 279).
The Run Flat Indicator 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 Run Flat
Indicator.
The Run Flat Indicator 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 apply-
ing the brakes and avoiding abrupt steering
maneuvers.
Warning!G
The Run Flat Indicator 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 ac-
cording to the incorrect value.

308 Operation
Tires and wheels
Switch on the ignition (page 40).
Press buttonè orÿ on the mul-
tifunction steering wheel repeatedly
until the standard display menu
appears in the multifunction display
(
page 149).
Press buttonj or k repeatedly
until the following message appears in
the multifunction display:
Tire Pressure Monitor
Active
Menu: R-button
Press the reset button (page 27).
The following message will appear in
the multifunction display:
Restart tire
pressure monitor?
Press button æ.
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 pressures and then moni-
tored.
If you wish to cancel activation:
Press button ç.Checking tire pressure electronically
with the Advanced Tire Pressure Moni-
toring System (Advanced TPMS)*,
(Canada only)
The TPMS only functions on wheels that
are equipped with the proper electronic
sensors. It monitors the tire inflation pres-
sure, as selected by the driver, in all four
tires. A warning is issued to alert you to a
decrease in pressure in one or more of the
tires.
Tire pressure inquiries are made using the
multifunction display. The present inflation
pressures are displayed only after a few
minutes’ travel time.
iReactivate the TPMS after adjusting the tire
inflation pressure to the inflation pressure rec-
ommended 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
(
page 294). Some vehicles may have supple-
mental tire inflation pressure information for
driving at high speeds (
page 301) or for vehi-
cle loads less than the maximum loaded vehicle
condition (
page 301). If such information is
provided, it can be found on the inside of the fuel
filler flap.
iThis device complies with RSS-210 of In-
dustry Canada. Operation is subject to the fol-
lowing two conditions:
(1) This device may not cause interference, and
(2) this device must accept any interference
received, including interference that may
cause undesired operation of the device.

311 Operation
Tires and wheels
If you want to set new reference values
manually:
Using the Tire and Loading Information
placard on the driver’s door B-pillar
(
page 294) or, if available, the
supplemental tire inflation pressure
information on the inside of the fuel
filler flap (
page 279), make sure the
tire inflation pressure of all four tires is
correct.
Press buttonè orÿ on the mul-
tifunction steering wheel repeatedly
until the standard display menu
appears in the multifunction display
(
page 143).
Press buttonj or krepeatedly
until the current inflation pressure for
each tire appears in the display or the
following message appears in the
multifunction display:
Tire pressure
displayed after
driving for
a few minutes
.
Press the reset button (page 27).
The following message will appear in
the multifunction display:
Restart tire
pressure monitor?
Press buttonæ.
The following message will appear in
the multifunction display:

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 pressures and then moni-
tored.
If you wish to cancel activation:
Press buttonç.
Warning!G
It is the driver’s responsibility to calibrate
the TPMS on the recommended cold infla-
tion pressure. Underinflated tires affect the
ability to steer or brake the vehicle. You
might lose control over the vehicle.
iRestart the TPMS after adjusting the tire in-
flation pressure to the inflation pressure recom-
mended for the vehicle operating condition. Tire
pressure should only be adjusted on cold tires.
Observe the recommended tire inflation pres-
sure on the Tire and Loading Information placard
on the driver’s door B-pillar (
page 294). Some
vehicles may have supplemental tire inflation
pressure information for driving at high speeds
(
page 301) or for vehicle loads less than the
maximum loaded vehicle condition
(
page 301). If such information is provided, it
can be found on the inside of the fuel filler flap.
