Practical advice Z
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver's door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout. Overloading
the tires can also result
in handling or steering problems, or brake
failure.
Check the tire pressure at least once a month.
Only check and correct tire pressures when
the tires are cold. Checking the tire pressure manually
In order to determine and adjust the tire
pressures, proceed as follows:
X Remove the valve cap of the tire you wish
to check.
X Press the
tire pressure gauge securely onto
the valve.
X Read the tire pressure and compare it with
the recommended value on the Tire and
Loading Information placard12
or on the tire
pressure plate on the B-pillar on the driver's
side of the vehicle.
X If necessary, increase the tire pressure to
the recommended value.
X If the tire pressure is too high, release air
by pressing down
the metal pin in the valve
using the tip of a pen, for example. Then,
check the tire pressure again using the tire
pressure gauge.
X Screw the valve cap onto the valve.
X Repeat the steps for the other tires. Tire pressure monitor
Important safety notes If a tire pressure monitor is installed, the
vehicle's wheels have sensors installed that
monitor the
tire
pressures in all four tires. The
tire pressure monitor warns you when the pressure drops in one or more of the tires. The
tire pressure monitor only functions if the
correct wheel electronics units are installed
in all wheels.
The tire pressure monitor has a yellow
0077
warning lamp in the instrument cluster for
indicating pressure loss/malfunctions (USA)
or pressure loss
(Canada). Depending on how
the warning lamp flashes or lights up, an
underinflated tire or a malfunction in the tire
pressure monitor is displayed:
R if the 0077 warning lamp is lit continuously,
the tire pressure on one or more tires is
significantly too low. The tire pressure
monitor is not malfunctioning.
R USA only: if the 0077 warning lamp flashes
for 60 seconds and then remains lit
constantly, the tire pressure monitor is
malfunctioning. G
Warning
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 placard on the driver’s door B-
pillar or 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 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 telltale when one or more of your
tires are significantly underinflated.
Accordingly, when the low tire pressure
telltale 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.

Wheels and tires
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 telltale.
USA only:
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the tire pressure monitoring system is not
operating properly. The TPMS malfunction
indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale 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 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.
i USA only:
If the tire pressure monitor is
malfunctioning, it may take more than
10 minutes for the 0077 tire pressure
warning lamp to inform you of the
malfunction by flashing for 60 seconds and
then remaining lit.
When the malfunction has been rectified,
the tire pressure warning lamp goes out
after driving for a few minutes. Information on tire pressures is displayed in
the on-board computer. After a few minutes
of driving, the current tire pressure of each
tire is shown in the on-board computer
i
The tire pressure values indicated by the
on-board computer may differ from those
measured at a gas station with a pressure
gauge. The tire
pressures shown by the on-
board computer refer to those measured at
sea level. At high altitudes, the tire pressure
values indicated by a pressure gauge are
higher than those shown by the on-board
computer. In this case, do not reduce the
tire pressures.

wireless headphones, two-way radios) is
operated inside the vehicle or in the vicinity
of the vehicle, this can interfere with the
operation of the tire pressure monitor.
