The 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 tire pressures 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 4-16, for an example of the tire
information label and its location on your vehicle. Also
see Inflation - Tire Pressure on page 5-57.
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 5-62 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.
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. The low tire
warning light comes on at each ignition cycle until the
problem is corrected. Some of the conditions that
can cause the malfunction light to come on are:
• One of the road tires has been replaced with the
spare tire. The spare tire does not have a TPMS
sensor. The TPMS malfunction light and DIC
message should go off once you re-install the road
tire containing the TPMS sensor.
• One or more TPMS sensors are missing or
damaged. The TPMS malfunction light should go off
when the TPMS sensors are installed and the sensor
matching process is performed successfully. See
your dealer/retailer for service.
• Replacement tires or wheels do not match your
vehicle’s original equipment tires or wheels. Tires
and wheels other than those recommended for your
vehicle could prevent the TPMS from functioning
properly. See Buying New Tires on page 5-64.
• Operating electronic devices or being near facilities
using radio wave frequencies similar to the TPMS
could cause the TPMS sensors to malfunction.
