monitor warns you if the pressure drops in one
or more of the tires. The tire pressure monitor
only functions if the corresponding sensors
are installed in all wheels.
Information on tire pressures is displayed in
the multifunction display. After a few minutes
of driving, the current tire pressure of each tire
is shown in the
Serv.

menu of the multifunc-
tion display, see illustration (example).

cally" section (

Important safety notes
G
WARNING
Each tire, including the spare (if provided),
should be checked at least once every two
weeks when cold and inflated to the pres-
sure recommended by the vehicle manufac-
turer on the Tire and Loading Information
placard on the driver's door B-pillar or the
tire pressure label on the inside of the fuel
filler flap. If your vehicle has tires of a differ-
ent size than the size indicated on the Tire
and Loading Information placard or, if availa-
ble, the tire pressure label, you should
determine the proper tire pressure for those
tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires are significantly underinflated. Accord-
ingly, when the low tire pressure telltale
lights up, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a signifi-
cantly 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 TPMS is not a substitute for
proper tire maintenance, and it is the driv-
er's responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the
system detects a malfunction, the warning
lamp will flash for approximately a minute
and then remain continuously illuminated.
This sequence will be repeated every time
the vehicle is started as long as the malfunc-
tion exists. When the malfunction indicator
is illuminated, the system may not be able to
detect or signal low tire pressure as inten-
ded.
TPMS malfunctions may occur for a variety
of reasons, including the installation of
incompatible replacement or alternate tires
or wheels on the vehicle that prevent the
TPMS from functioning properly. Always
check the TPMS malfunction telltale after
replacing one or more tires or wheels on
your vehicle to ensure that the replacement
or alternate Tires and wheels allow the
TPMS to continue to function properly.
It is the driver's responsibility to set the tire
pressure to that recommended for cold tires
which is suitable for the operating situation
(
Y
page 307). Note that the correct tire pres-
sure for the current operating situation must
first be taught-in to the tire pressure monitor.
If a substantial loss of pressure occurs, the
warning threshold for the warning message is
aligned to the taught-in reference values.
Restart the tire pressure monitor after adjust-
ing the pressure of the cold tires
(
Y
page 314). The current pressures are
saved as new reference values. As a result, a
warning message will appear if the tire pres-
sure drops significantly.
