This vehicle may have a Tire Pressure Monitor System (TPMS). The 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.
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. 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 , for an example of the Tire and Loading Information label and its location on your vehicle. Also see Inflation - Tire Pressure.
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 and Tires.
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. |
| • | The initialization (reset) procedure failed. See "TPMS Reset" later in this section. |
| • | 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 the 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. |
| • | Operating electronic devices or being near facilities using radio wave frequencies similar to the TPMS could cause the TPMS sensors to malfunction. |
| • | If tire chains are installed on the vehicle. |
| • | If there is a lot of snow or ice around the wheels or wheel housings. |
| • | If a window tint that affects the radio wave signals is installed. |
If the TPMS is not functioning it cannot detect or signal a low tire condition. See your dealer/retailer for service if the TPMS malfunction light comes on and stays on.
TPMS Reset
The TPMS sensors and transmitters have unique identification codes. Anytime you replace a TPMS sensor or transmitter the identification codes need to be registered and the TPMS needs to be reset (initialized). When the system is initialized, the current air pressure in the tires is set as the tire pressure benchmark. The tire pressure warning system determines decreased air pressure by comparing tire pressure to the benchmark pressure stored in the TPMS.
Do not reset the TPMS without first correcting the cause of a low-tire condition.
To reset the system:
- Park the vehicle at a safe place and apply the parking brake. Turn the engine off.
- Turn the ignition to ACC/ACCESSORY or LOCK/OFF.
- Adjust the tire pressure of all the installed tires to the specified cold tire inflation pressure level indicated on the Tire and Loading Information label attached to the vehicle.
- Turn the ignition to ON/RUN with the engine off.
- Press and hold the tire pressure warning reset switch until the tire pressure warning light flashes slowly on/off three times.
Wait for a few minutes with the ignition in ON/RUN, and then turn the ignition to ACC/ACCESSORY or LOCK/OFF.
If the low-tire pressure warning light does not flash three times while you press and hold the reset button, the reset has failed. Repeat the reset process. If the reset cannot be performed, see your dealer/retailer for service.
If you press the tire pressure reset switch while the vehicle is moving, the reset is not performed. If you press the tire pressure reset switch accidentally and initialization is performed, adjust the tire pressure to the specified level and perform the reset procedure again.
