531 Operation
Tires and wheels
Checking tire pressure electronically
with the Advanced Tire Pressure
Monitoring System (Advanced TPMS)The Advanced TPMS only functions on
wheels that are equipped with the proper
electronic sensors. It monitors the tire in-
flation pressure, 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 inflation pressure inquiries are made
using the multifunction display. The
present inflation pressures are displayed
only after a few minutes of travel time.
iThe Advanced Tire Pressure Monitoring
System (Advanced TPMS) is equipped with a
combination low tire pressure/TPMS malfunc-
tion telltale in the instrument cluster
(
page 576). Depending on how the telltale illu-
minates, it indicates a low tire inflation pressure
condition or a malfunction in the Advanced
TPMS system itself:

If the telltale illuminates continuously, one
or more of your tires is significantly underin-
flated. There is no malfunction in the
Advanced TPMS.

If the telltale flashes for 60 seconds and
then stays illuminated, the Advanced TPMS
system itself is not operating properly.
iUSA only:
This device complies with Part 15 of the FCC
Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful
interference, and
(2) this device must accept any interference
received, including interference that may
cause undesired operation.
Any unauthorized modification to this device
could void the user’s authority to operate the

Canada. Operation is subject to the following

(2) this device must accept any interference
received, including interference that may

Any unauthorized modification to this device
could void the user’s authority to operate the

of a tire inflation pressure gauge of an air hose,
e.g. gas station equipment, and the vehicle’s
control system can occur. Usually the readings
issued by the control system are more precise.

532 Operation
Tires and wheels
Switch on the ignition (page 336).
Press( or& to select the menu
“Service”.
Press$ or% to select “Tire
pressure”.
Press#.
iWhen the message “Tire pressures dis-
played after driving a few minutes” appears in
the display, the individual inflation pressure val-
ues are matched with the tires. The individual
values are displayed after a few minutes driving.
Warning!G
It is the driver’s responsibility to calibrate
the Advanced TPMS on the recommended
cold inflation pressure. Underinflated tires
affect the ability to steer or brake the vehi-
cle. You might lose control over the vehicle.
iWith a spare wheel without wheel sensor
mounted, the system may still indicate the tire
inflation pressure of the removed wheel for some
minutes. If this happens, keep in mind that the
indicated value where the spare wheel is mount-
ed does not reflect the actual spare tire inflation
pressure.
Warning!G
The Advanced TPMS does not indicate a
warning for wrongly selected inflation pres-
sures. Always adjust tire inflation pressure
according to the Tire and Loading Informa-
tion placard on the driver’s door B-pillar or,
if available, the supplemental tire inflation
pressure information on the inside of the
fuel filler flap.
The Advanced TPMS is not able to issue a
warning due to a sudden dramatic loss of
pressure (e.g. tire blowout caused by a for-
eign object). In this case bring the vehicle to
a halt by carefully applying the brakes and
avoiding abrupt steering maneuvers.

533 Operation
Tires and wheels
Warning!G
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
Tire and Loading Information placard on the
driver’s door B-pillar or, if available, the tire
inflation pressure label on the fuel filler flap.
If your vehicle has tires of a different size
than the size indicated on the Tire and
Loading Information placard or, if available,
the tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.
As an added safety feature, your vehicle has
been equipped with an advanced tire pres-
sure monitoring system (Advanced TPMS)
that illuminates a low tire pressure telltale
when one or more of your tires is significant-
ly underinflated. Accordingly, when the low
tire pressure telltale illuminates, you should
stop and check your tires as soon as possi-
ble, and inflate then to the proper pressure.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to
tire failure.
Underinflation also reduces fuel efficiency
and tire tread life, and may effect the vehi-
cle’s handling and stopping ability. Please
note that the Advanced TPMS is not a sub-
stitute for proper tire maintenance, and it is
the driver’s responsibility to maintain cor-
rect tire pressure, even if underinflation has
not reached the level to trigger illumination
of the Advanced TPMS low tire pressure tell-
tale.
Your vehicle has also been equipped with an
Advanced TPMS malfunction indicator to in-
dicate when the system is not operating
properly. The Advanced TPMS malfunction
indicator is combined with the low tire pres-
sure telltale. When the system detects a
malfunction, the telltale will flash for approx-
imately one minute and then remain contin-
uously illuminated. This sequence will
continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the
malfunction indicator is illuminated,the system may not be able to detect or sig-
nal low tire pressure as intended.
Advanced TPMS malfunctions may occur for
a variety of reasons, including the installa-
tion of replacement or alternate tires or
wheels on the vehicle that prevent the Ad-
vanced TPMS from functioning properly. Al-
ways check the Advanced TPMS
malfunction telltale after replacing one or
more tires or wheels on your vehicle to en-
sure that the replacement or alternate tires
and wheels allow the Advanced TPMS to
continue to function properly.
iIf a condition causing the Advanced TPMS to
malfunction develops, it may take up to
10 minutes for the system to signal a malfunc-
tion using the Advanced TPMS telltale flashing
and illumination sequence.
The telltale extinguishes after a few minutes driv-
ing if the malfunction has been corrected.
iOperating radio transmission equipment
(e.g. wireless headsets, two-way radios) in or
near the vehicle could cause the Advanced TPMS
to malfunction.

534 Operation
Tires and wheels
Reactivating Advanced TPMS
The Advanced TPMS must be reactivated
when you have adjusted the tire inflation
pressure to a new level (e.g. because of dif-
ferent load or driving conditions). The Ad-
vanced TPMS is then recalibrated to the
current tire inflation pressures.
Using the Tire and Loading Information
placard on the driver’s door B-pillar
(
page 523) or, if available, the sup-
plemental tire inflation pressure
information on the inside of the fuel fill-
er flap (
page 509), make sure the tire
inflation pressure of all four tires is
correct.
Switch on the ignition (page 336).
Press( or& to select the menu
“Service”.
Press$ or% to select
“Tire pressure”.
Press#.
You will see

the current inflation pressures for
each tire
or

the message
“Tire pressures

appear in the multifunction display.
Press%.
The message
“Use current pressure
values as new
reference values
To confirm press &#34;OK&#34;”
appears in the multifunction display.
Warning!G
It is the driver’s responsibility to calibrate
the Advanced TPMS on the recommended
cold inflation pressure. Underinflated tires
affect the ability to steer or brake the vehi-
cle. You might lose control over the vehicle.
iReactivate the Advanced TPMS after adjust-
ing the tire inflation pressure to the inflation
pressure recommended for the vehicle operating
condition. Tire inflation pressure should only be
adjusted on cold tires. Observe the recommend-
ed tire inflation pressure on the Tire and Loading
Information placard on the driver’s door B-pillar
(
page 523). Some vehicles may have supple-
mental tire inflation pressure information for
driving at high speeds (
page 529) or for vehi-
cle 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
(
page 509).
iAfter wheel rotation or sensor replacement,
the vehicle must be parked for 20 minutes be-
fore attempting to reactivate the Advanced
TPMS.

the ability to steer or brake the vehicle. You
may lose control of the vehicle.
