9-50 Vehicle Service and Care 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 the vehicle, shows the size of the vehicle's original equipment tires and the correct inflation pressure for the tires when they are cold. See Loading the Vehicle on page 8-32, for an example of the Tire and Loading Information label and its location on your vehicle. Also see Inflation - Tire Pressure on page 9-47. The 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 9-53 and Tires on page 9-41. The TPMS operates on a radio frequency and complies with RSS-210 of Industry and Science Canada. Operation is subject to the following two conditions: 1. This device may not cause interference. 2. This device must accept any interference received, including interference that may cause undesired operation of the device. Changes or modifications to this system by other than an authorized service facility could void authorization to use this equipment. When a low tire pressure condition is detected, the low tire pressure warning light, located on the instrument panel cluster, comes on. This light also comes on for a few seconds and then goes off when you turn the ignition to ON/RUN. This indicates the TPMS is functioning properly. If the low-tire pressure warning light comes on while driving the vehicle, the system may have detected a low-tire condition. You need to stop as soon as possible and check the tires. 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. Tire Pressure Monitor Operation The Tire Pressure Monitor System (TPMS) warns the driver when a low tire pressure condition exists. TPMS sensors are mounted onto each tire and wheel assembly, excluding the spare tire and wheel assembly.
