When trouble arises
WARNING
As an added safe ty feature, your
vehicle has been equipped with a
tire pressure m onitoring system
(TPMS-tire pressure warning sys-
tem) that illuminates a low tire
pressure telltale (tire pressure
warning light) when one or more
of your tires is significantly under-
inflated. Accordingly, when the
low tire pressure telltale (tire pres-
sure warning light) 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 vehi-
cle’s handling and stopping ability.
Please note that the TPMS (tire
pressure warning system) is not a
substitute for pro per tire mainte-
nance, and it is the driver’s
responsibility to maintain correct
tire pressure, even if under-infla-
tion has not reach ed the level to
trigger illumination of the TPMS
low tire pressure telltale (tire pres-
sure warning light).
Your vehicle has also been
equipped with a TPMS (tire pres-
sure warning system) malfunc-
tion indicator to indicate when the
system is not operating properly.
The TPMS (tire pressure warning
system) malfunction indicator is
combined with the low tire pres-
sure telltale (tire pressure warning
light). When the system detects a
malfunction, the te lltale will flash
for approximately one minute and
then remain continuously illumi-
nated. This sequence will con-
tinue upon subsequent vehicle
start-ups as long as the malfunc-
tion exists. When the malfunction
indicator is illuminated, the sys-
tem may not be ab le to detect or
signal low tire pressure as
intended.
TPMS (tire pressure warning sys-
tem) malfunctions may occur for a
variety of reasons, including the
installation of replacement or
alternate tires or wheels on the
vehicle that prevent the TPMS
(tire pressure warning system)
from functioning properly. Always
check the TPMS (tire pressure
warning system) malfunction tell-
tale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow
the TPMS (tire pressure warning
system) to continue to function
properly.
NOTICE
■To ensure the tire pressure
warning system operates
properly
Do not install tires with different
specifications or makers, as the
tire pressure warning system may
not operate properly.
