GWarning
Each tire, including the spare (if provided), should be checked every other week when cold and
inflated to the inflation pressure recommended 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 inside of 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 a tire pressure monitoring
system (TPMS) that illuminates a low tire pressure warning lamp when one or more of your tires
are significantly underinflated. Accordingly, when the low tire pressure warning lamp illuminates,
you should stop and check your tires as soon as possible, 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 vehicle's handling
and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance,
and it is the driver's responsibility to maintain correct tire pressure, even if underinflation has
not reached the level to trigger illumination of the TPMS low tire pressure warning lamp.
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 warning lamp. When the system detects a malfunction, the warning lamp will flash for
approximately one minute and then remain continuously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction
indicator is lit, the system may not be able to detect or signal low tire pressure as intended.
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 warning lamp 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.

Tire pressure monitoring system
(USA only)
Important safety information
The tire pressure monitoring system consists
of sensors installed in the vehicle wheels that
monitor the air pressure in all four tires. The
tire pressure monitoring system warns you
when the pressure in one or more tires
decreases. It only works when the
corresponding sensors are installed on all the
wheels.
The tire pressure monitor informs you via a
yellow warning lamp in the instrument cluster
about pressure loss or if the system is
malfunctioning. Whether the warning lamp
flashes or lights up indicates whether a tire
pressure is too low or the tire pressure
monitor is malfunctioning:
R If the warning lamp is lit up constantly, one
or more of your tires are significantly
underinflated. The tire pressure monitor is
not malfunctioning.
R If the warning lamp flashes for 60 seconds
and is then lit constantly, the tire pressure
monitor is malfunctioning.GWarning!
Each tire, including the spare (if provided),
should be checked at least once a month
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the tire and loading
information table on the driver's door B-pillar
or the tire inflation pressure table on the
inside of the fuel filler flap. If your vehicle has
tires of a different size than the size indicated
on the tire and loading information table or
the tire inflation pressure table, you should
determine the proper tire inflation pressure
for those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor
(TPMS). An indicator lamp lights up if one or
more of your tires are significantly
underinflated. Accordingly, when the low tire
pressure indicator lamp lights up, you should
stop and check your tires as soon as possible,
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 vehicle's
handling and stopping ability. Please note that
the TPMS is not a substitute for proper tire
maintenance and it is the driver's
responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level at which the low tire
pressure indicator lamp of the TPMS lights up.
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 indicator lamp. When the
system detects a malfunction, the indicator
lamp will flash for approximately 1 minute and

then remain illuminated. This sequence will
continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the
malfunction indicator is lit, the system may
not be able to detect or signal low tire
pressure as intended.
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 indicator 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.
i If the tire pressure monitoring system
malfunctions, it may take up to 10 minutes
before the malfunction is displayed to you
by the tire pressure warning lamp flashing
for 60 seconds and then remaining lit.
When the error has been rectified, the tire
pressure warning lamp goes out after a few
minutes of driving.
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 multifunction display.
i The tire pressure values in the on-board
computer may deviate from the inflation
pressure as measured using a tire pressure
checker at the filling station. The tire
pressures shown in the on-board computer
refer to pressures at sea level. At high
altitudes, a tire pressure checker will
display a higher tire pressure than the on-
board computer. In this case do not reduce
the tire pressure.
i If radio transmitting equipment (e.g. radio
headphones, a two-way radio) is operated
in or near the vehicle, this can lead to the
function of the tire pressure monitor being
impaired.i 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 withstand 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 equipment.

After a teach-in process, the tire pressure
monitor automatically detects new wheels or
new sensors. As long as it is not possible to
allocate tire pressure values to individual
wheel positions, the Tire Pressure
Monitor Active message appears instead
of the tire pressure display. The tire pressures
are already being monitored.
i If a spare wheel is installed, the system
may continue to show the tire pressure of
the wheel that has been removed for a few
minutes. If this occurs, note that the value

pressure for the spare wheel.
TPMS warning messages
If the TPMS detects a significant pressure
loss on one or more tires, a warning message
is shown in the multifunction display. In
addition, a warning tone sounds and the tire
pressure warning lamp lights up in the
instrument cluster.
Each tire in which a significant pressure loss
has been detected is highlighted with a red
triangle.
Restarting the tire pressure monitoring
system
GWarning
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, all existing
warning messages are deleted and the
warning lamps go out. The currently set tire
pressures are adopted as the specified values
for monitoring.
The TPMS must be restarted when you set the
tire pressure to a new value (as a result of
changed handling or load characteristics, for
example). The TPMS then monitors the new
tire pressure values.
Restart the TPMS after the tire pressure has
been set, as desired, according to the
recommended values for the driving
conditions ( Y page 306). Only correct tire
pressures on cold tires. Comply with the tire
pressures recommended on the Tire and
Loading Information placard on the B-pillar on
the driver's side. Additional tire pressure
values for driving at high speeds or with heavy
loads can be found in the tire pressure table
on the inside of the fuel filler flap.
