Tire Pressure Monitoring System
WARNING
Excessive or insufficient inflation may shorten tire life, adversely affect vehicle handling, and cause a sudden tire failure that may result in loss of vehicle control and an accident.
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 certification label or the tire and loading information label. (If your vehicle has tires of a different size than the size indicated on the vehicle certification label or tire and loading information label, you should determine the correct 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 warning light when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure warning light 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 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 illuminate the TPMS Low Tire Pressure Warning Light.
Your vehicle is also equipped with a TPMS Malfunction Indicator to indicate when the system is not functioning properly. The TPMS Malfunction Indicator is combined with the Low Tire Pressure Warning Light. When the system detects a malfunction, the light will flash for approximately one minute and then remain steadily illuminated. This sequence will continue during 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 indicator 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.
NOTICE
If any of the following occurs, have the system checked by an authorized HYUNDAI dealer.
1. The Low Tire Pressure Warning Light / TPMS Malfunction Indicator does not illuminate for 3 seconds when the ignition switch is in the ON position or the engine is running.
2. The TPMS Malfunction Indicator continues to illuminate after flashing for approximately 1 minute.
3. The Low Tire Pressure Warning Light remains illuminated.
