289 Operation
Tires and wheels
Checking tire inflation pressure
manually
Follow the steps below to achieve correct
tire inflation pressure:
Remove the cap from the valve on one
tire.
Firmly press a tire gauge onto the
valve.
Read tire inflation pressure on tire
gauge and check against the recom-
mended tire inflation pressure on the
Tire and Loading Information placard
on the driver’s door B-pillar
(
page 280). If necessary, add air to
achieve the recommended tire inflation
pressure.
Install the valve cap.
Repeat this procedure for each tire.Checking tire pressure electronically
with the Advanced Tire Pressure
Monitoring System (Advanced TPMS)
iIf you have overfilled the tire, release tire
inflation pressure by pushing the metal stem of
the valve with e.g. a tip of a pen. Then recheck
the tire inflation pressure with the tire gauge.
iUSA only:
The T
ire Pressure Monitoring System (TPMS) is
equipped with a combination low tire pres-
sure/TPMS malfunction telltale in the instru-
ment cluster (
page 26). Depending on how the
telltale illuminates, it indicates a low tire pres-
sure condition or a malfunction in the TPMS sys-
tem itself:

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

If the telltale flashes for 60 seconds and
then stays illuminated, the TPMS system it-
self is not operating properly.
iUSA only:

290 Operation
Tires and wheels
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.Switch on the ignition (page 39).
Press buttonj ork until the
current inflation pressures for each tire
appear in the multifunction display.
Example illustration
iPossible differences between the readings
of a tire 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.
iWhen the vehicle has been parked for longer
than 20 minutes, the message
Tire pressure
displayed only after driving for a few
minutes
appears in the multifunction display.
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.
iWith a spare wheel mounted, the system
may still indicate the tire inflation pressure of the
removed road wheel for some minutes. If this
happens, keep in mind that the indicated value
where the spare wheel is mounted does not
reflect the actual spare tire inflation pressure.

291 Operation
Tires and wheels
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.
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 or the
tire inflation pressure label (if available). If
your vehicle has tires of a different size than
the size indicated on the Tire and Loading
Information placard or the tire inflation
pressure label (if available), 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 them 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 affect 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.
USA only: Your vehicle has also been
equipped with a Advanced TPMS malfunc-
tion indicator to indicate when the system is
not operating properly. The Advanced TPMS
malfunction indicator is combined with the
low tire pressure telltale. When the system
detects a malfunction, the telltale will flash
for approximately 1 minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups
as long as the malfunction exists.

Tire inflation pressure warnings
If the system detects a significant loss of
tire inflation pressure in one or more than
one tire, a message appears in the multi-
function display.
Example illustration
The respective tire is indicated by a red
rectangle. In addition, a warning signal
sounds.Restarting Advanced TPMS
The TPMS usually recognizes new refer-
ence values automatically, for example
when you have

adjusted the tire inflation pressure

changed wheels or tires

mounted new wheels or tires
USA only: When the malfunction indicator is
illuminated, the system may not be able to
detect or signal low tire pressure as
intended.
USA only: Advanced TPMS malfunctions
may occur for a variety of reasons, including
the installation of replacement or alternate
tires or wheels on the vehicle that prevent
the Advanced TPMS from functioning prop-
erly. Always check the Advanced TPMS mal-
function telltale after replacing one or more
tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the Advanced TPMS to contin-
ue to function properly.
iOperating radio transmission equipment
(e.g. wireless headsets, two-way radios) in or
near the vehicle could cause the Advanced
TPMS to malfunction.
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.


293 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 280) or, if available, the
supplemental tire inflation pressure
information on the inside of the fuel
filler flap (
page 264), 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.
Press buttonj ork repeatedly
until you see the current inflation
pressures for each tire appear in the
multifunction display or the following
message appears 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 theç button.
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 280). Some
vehicles may have supplemental tire inflation
pressure information for driving at high speeds
(
page 287) or for vehicle loads less than the
maximum loaded vehicle condition
(
page 287). If such information is provided, it
can be found on the inside of the fuel filler flap
(
page 264).
