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

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
displayed for the position where the
emergency spare wheel/spare wheel is
installed is not the same as the current tire
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 336). 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.XMake sure that the tire pressure is set

The Tire Pressure Monitor
Restarted message appears in the

After driving for a few minutes, the system
confirms that the current tire pressure
values are within the specified range. The
new tire pressure values are then accepted
as reference values and monitored.XTo cancel restart: press the X button.

If the positions of the wheels on the
vehicle have been changed, the tire
pressure may be shown in the wrong
position briefly. This will be corrected after
driving for a few minutes and the tire
pressure will be displayed in the correct
position.
