TPMS lamp.
The Tire Pressure Monitoring System (TPMS) provides a low pressure warning but does not re-inflate the tires. Tire pressures should be checked regularly, using an accurate pressure gauge when the tires are cold. Failure to do so could result in an accident, potentially leading to serious injury or death.
The TPMS cannot predict, or warn of, a sudden tire failure, or register damage to a tire. Regularly check the condition of the tires, especially if the vehicle is driven off-road. Failure to do so could result in an accident, potentially leading to serious injury or death.
The tire pressure warning lamp illuminates when one or more of the tires are significantly under-inflated. A message is also displayed. Stop and check the tires as soon as possible. Inflate the tires to the recommended inflation pressures for the vehicle's loading condition. See TIRE PRESSURE MONITORING SYSTEM (TPMS) (YELLOW) and TIRE PRESSURES.
The tire pressure warning lamp illuminates if a temporary-use spare wheel is used as a road wheel. See TEMPORARY USE SPARE WHEEL AND TIRE CHANGE.
The TPMS constantly monitors the tire pressure in each road wheel. The spare wheel tire pressure is not monitored.
To confirm if TPMS is fitted to the vehicle: Switch on the vehicle’s ignition and check for the presence of a TPMS lamp in the instrument panel. Vehicles with a TPMS lamp have TPMS.

A special service kit is required when changing a tire fitted with a TPMS valve.
Non-approved accessories may interfere with the TPMS. If this occurs, the TPMS warning lamp flashes and then illuminates permanently.
Different types of tires may affect the performance of the TPMS. Always replace the tires in accordance with recommendations.
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability.
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.
The instrument panel displays the TPMS warning lamp and related warning messages if a low tire pressure, or a fault, is detected.
The TPMS warning lamp operation and warning messages are as follows:
| Lamp operation and warning message | Issue | Action |
|---|---|---|
| The TPMS warning lamp illuminates for 3 seconds and then extinguishes. | Tire pressures are all correct. | No action required. |
| The TPMS warning lamp illuminates permanently when the ignition is switched on. A low tire pressure warning message is displayed in the instrument panel. | One or more tire pressures are low. | Check and adjust the tire pressures of the tires shown in the instrument panel. |
| The TPMS warning lamp flashes for 75 seconds when the ignition is switched on, and then illuminates permanently. A warning message is displayed in the instrument panel to advise that a tire is not being monitored. A yellow cross appears on the tire in the warning message and in the Tire Pressures Menu. | The vehicle has lost communication with one of the tires. | Check and adjust all tire pressures, if required, before driving the vehicle. If the problem persists, contact a retailer/authorized repairer. |
| The TPMS warning lamp flashes for 75 seconds when the ignition is switched on, and then illuminates permanently. No warning message is displayed in the instrument panel. Two or more yellow crosses appear on the tires in the Tire Pressures Menu. | The vehicle has lost communication with more than one of the tires. | Check and adjust all tire pressures, if required, before driving the vehicle. If the problem persists, contact a retailer/authorized repairer. |
| The TPMS warning lamp flashes for 75 seconds when the ignition is switched on, and then illuminates permanently. No warning message is displayed in the instrument panel. No yellow crosses appear on the tires and no tire pressures are displayed in the Tire Pressures Menu. | Unknown fault with the TPMS. | Check and adjust all tire pressures, if required, before driving the vehicle. If the problem persists, contact a retailer/authorized repairer. |
