Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn the
driver when a low tire pressure
condition exists. TPMS sensors are
mounted onto each tire and wheel
assembly, excluding the spare tire
and wheel assembly. The TPMS
sensors monitor the air pressure in
the vehicle’s tires and transmit the
tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning light on
the instrument panel cluster.
The low tire pressure warning light
comes on at each ignition cycle
until the tires are inflated to
the correct inflation pressure.
The low tire pressure warning light
may come on in cool weather
when the vehicle is first started, and
then turn off as you start to drive.
This may be an early indicator
that the air pressure in the tire(s)
are getting low and need to be
inflated to the proper pressure.
A Tire and Loading Information
label, attached to your vehicle,
shows the size of your vehicle’s
original equipment tires and
the correct inflation pressure for
your vehicle’s tires when they
are cold. See Loading the Vehicle
on page 4-28, for an example of the
Tire and Loading Information
label and its location on your
vehicle. Also see Inflation - Tire
Pressure on page 5-49.
Your vehicle’s TPMS system can
warn you about a low tire pressure
condition but it does not replace
normal tire maintenance. See Tire
Inspection and Rotation on
page 5-56 and Tires on page 5-43.
Notice: Liquid tire sealants could
damage the Tire Pressure Monitor
System (TPMS) sensors. Sensor
damage caused by using a tire
sealant is not covered by your
warranty. Do not use liquid tire
sealants.
TPMS Malfunction Light
The TPMS will not function properly
if one or more of the TPMS
sensors are missing or inoperable.
When the system detects a
malfunction, the low tire warning
light flashes for about one minute
and then stays on for the
remainder of the ignition cycle.
