TPMS (TIRE PRESSURE MONITORING SYSTEM) TIRE PRESSURE WARNING LAMP "ON"
This Technical Service Bulletin supersedes 08-SS-002 to clarify the warranty coverage.
DESCRIPTION:
Tire pressure warning lamp ON
If a customer comments that the TPMS (Tire Pressure Monitoring System tire pressure warning lamp is "ON" for the first few miles of driving after a
cold start or stays "ON" continuously, particularly in cold ambient temperatures, please be sure to inform the customer that the system is operating
correctly to warn of a low tire pressure condition, and a system diagnosis may not be required. The customer should be made aware of the following:
^
This condition may be caused by low tire pressure if the tire pressure falls below the low warning threshold for any reason including low temperature
effects.
NOTE:
For vehicles equipped with the TPMS, the threshold pressure limit is 25% below the vehicle's recommended cold tire pressure, shown on the placard
located on the driver side B-pillar.
^
Recommend the customer inflate tires when they are cold (before being driven if possible) or compensate for being hot by setting the tire pressure to
3 or 4 psi above specification.
NOTE:
The tire pressure will vary with temperature by about 1 psi (6.9 kpa) for every 12°F (6.5°C).
^
Recommend the customer check and adjust all tire pressures, including the spare tire, once a month. (For additional information, suggest the
customer refer to the vehicle owner's manual.)
WARRANTY INFORMATION
Adjusting the tire air pressure is included in the PDI process, and is not covered under normal warranty. Tire air pressure is a normal maintenance item.
