the proper tire inflation pressure for
those tires.)
— If a wheel was replaced on each
axle.
— If a tire was changed.
— If the tire pressure was changed,
or wheels were rotated or re-
placed.
— If there are snow chains on the
tires. Using snow chains can cause
the system to give false warnings
because snow chains increase tire
circumference.
As an added safety feature, your ve-
hicle has been equipped with a Tire
Pressure Monitoring System (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly underinflated.
Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly 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.
The Tire Pressure Monitoring System
(TPMS) may not react at first or
may not react at all when you are
driving in a sporty manner, or on
snow-covered or unpaved roads,
when you are driving with snow
chains, or in certain other situations.
A change in the tread circumference
of a tire is signaled by the Tire Pres-
sure Monitoring System indicator in
the instrument cluster (telltale).
Please note that the TPMS is not
a substitute for proper tire mainte-
nance, and it is the driver's responsi-
bility to maintain correct tire pres-
sure, even if underinflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
telltale.
The tire pressure recommended for
the tires originally installed on the
vehicle is on a sticker on the driver
door jamb → page 276, Tire inflation
pressure.
Your vehicle has also been equipped
with a TPMS malfunction indicator
to indicate when the system is not
operating properly. The TPMS mal-
function indicator is combined with
the low tire pressure telltale. When
the system detects a malfunction,
the telltale will flash for approxi-
mately one minute and then remain
continuously illuminated. This se-
quence will continue upon subse-
quent vehicle start-ups as long as
the malfunction exists.
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the infla-
tion pressure recommended by the
vehicle manufacturer on the vehicle
placard or tire inflation pressure la-
bel. (If your vehicle has tires of a dif-
ferent size than the size indicated on
the vehicle placard or tire inflation
pressure label, you should determine
