Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's
responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to
trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS malfunction indicator is combined with the low tire
pressure telltale.
When the system detects a malfunction, the telltale will flash for approximately one minute and
then remain continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the installation of replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow the TPMS to continue to function properly.
NOTE:
Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C) of air temperature change.
Keep this in mind when checking tire pressure inside a garage, especially in the Winter. Example:
If garage temperature is 68°F (20°C), and the outside temperature is 32°F (0°C), then the cold
tire inflation pressure should be increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every
12°F (7°C) for this outside temperature condition.
The TPMS has been optimized for the original equipment tires and wheels. TPMS pressures
and warning have been established for the tire size equipped on your vehicle. Undesirable
system operation or sensor damage may result when using replacement equipment that is not
of the same size, type, and/or style. Aftermarket wheels can cause sensor damage. Do not use
tire sealant from a can, or balance beads if your vehicle is equipped with a TPMS, as damage
to the sensors may result.
