Tire Pressure Monitor System
If your vehicle has this feature, it is designed to alert
you when the system detects a large change in
the pressure of one tire. The system cannot alert you
before you drive that a tire is low or at. You must begin
driving before the system will work properly. The
system works with the brake control system and is
designed to detect differences in the tire rotation speeds
that are caused by changes in tire pressure. The tire
pressure monitoring system does not replace normal tire
maintenance, seeTires on page 5-52,Tire Inspection
and Rotation on page 5-62andWhen It Is Time for New
Tires on page 5-64.
This light, on the
instrument panel cluster,
comes on when the
tire pressure monitoring
system detects a low-tire
condition.
This light will also come on for a few seconds and then
go off when you turn the ignition to ON. This indicates
that the tire pressure monitoring system is functioning
properly. If the low-tire pressure warning light comes on
while driving your vehicle, the system may havedetected a low-tire condition. You need to stop as soon
as possible and check your tires for damage. If a tire
is at, seeIf a Tire Goes Flat on page 5-69and
Changing a Flat Tire on page 5-70. Also check the
tire pressure in all four tires, and set them to the
speci ed level shown on the tire and loading label.
SeeIn ation - Tire Pressure on page 5-58for
additional information.
Note:The tire pressure monitoring system on your
vehicle will warn you when one of your tires is
signi cantly under-in ated and when some combinations
of your tires are signi cantly under-in ated. However,
there are other combinations of signi cantly
under-in ated tires for which your tire pressure
monitoring system may not warn you. These other
combinations are relatively common, accounting
for approximately half the instances in which vehicles
have signi cantly under-in ated tires. For example, your
system may not warn you when both tires on the
same side or on the same axle of your vehicle are
signi cantly under-in ated. It is particularly important,
therefore, for you to check the tire pressure in all of your
tires regularly and maintain proper pressure.
In order for the tire pressure monitoring system to work
properly you will need to reset (initialize) the tire
pressure monitoring system. Any time you check and/or
adjust a tire’s pressure, repair or replace a tire or
wheel or rotate the tires the tire pressure monitor system
needs to be reset.

The low-tire pressure warning light may not come on
even if the tire in ation pressure is low, or it may come
on when the tire in ation pressure is set correctly
under the following circumstances:
A compact spare tire, snow tires, or tire chains are
installed on your vehicle.
The tires are over-in ated, or the tire in ation
pressure suddenly drops due to a tire bursting
or other causes.
The vehicle is driven on a slippery road surface
such as rough or frozen roads.
The vehicle speed is less than 19 mph (30 km/h),
and the driving duration is less than ve minutes.
The tires are made by a different manufacturer or
differ in tread pattern than the original
equipment tires.
Rapid acceleration/deceleration or multiple
consecutive sharp turns.
Towing a trailer.
The vehicle is loaded over the limit or not
balanced properly.
The initialization (reset) procedure was not
performed correctly after replacing or rotating tires
or wheels.
The outside temperature is below 32°F (0°C) or
above 104°F (40°C).
Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires as
soon as possible and check wheel alignment. Also
check for damaged tires or wheels. SeeWhen It Is Time
for New Tires on page 5-64andWheel Replacement
on page 5-67for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The rst rotation
is the most important. SeePart A: Scheduled
Maintenance Services on page 6-4for scheduled
rotation intervals.
