At the same time a message to check the pressure
in a specific tire appears on the Driver Information
Center (DIC) display. The low tire pressure warning
light and the DIC warning message come on at
each ignition cycle until the tires are inflated to the
correct inflation pressure. Using the DIC, tire pressure
levels can be viewed by the driver. For additional
information and details about the DIC operation and
displays see DIC Operation and Displays on page 3-48
and DIC Warnings and Messages on page 3-53.
When a low tire pressure
condition is detected, the
TPMS illuminates the
low tire pressure warning
light located on the
instrument panel cluster.
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 could 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
Your Vehicle on page 4-33, for an example of the
Tire and Loading Information label and its location
on your vehicle. Also see Inflation - Tire Pressure
on page 5-59.
Your vehicle's TPMS can warn you about a low tire
pressure condition but it does not replace normal
tire maintenance. See Tire Inspection and Rotation
on page 5-66 and Tires on page 5-51.
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.
