Checking the tire pressure manually
Read the tire pressure recommended for the
#
current operating conditions from the tire and
loading information placard or the tire pres-
sure table. Observe the notes on tire pressure.
Remove the valve cap of the tire to be
#
checked.
Press the tire pressure gauge securely onto
#
the valve.
Read the tire pressure.
#
If the tire pressure is lower than the recom-
#
mended value, increase the tire pressure to
the recommended value.
If the tire pressure is higher than the recom-
#
mended value, release air. To do so, press
down the metal pin in the valve, e.g. using the
tip of a pen. Then check the tire pressure
again using the tire pressure gauge.
Screw the valve cap onto the valve.

Tire pressure monitoring system
▌Function of the tire pressure monitoring system
& DANGER Risk of accident due to incorrect
tire pressure
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommen-
ded by the vehicle manufacturer on the vehi-
cle placard or tire inflation pressure label. (If
your vehicle has tires of a different size than
the size indicated on the vehicle placard or
tire inflation pressure label, you should deter-
mine 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 pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
Wheels and tires 351
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead
to tire failure. Under-inflation 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 driv-
er's responsibility to maintain correct tire
pressure, even if under-inflation 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 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.
