Check Tire Pressure

• You can check the tire pressure in the Assist mode on the cluster. Refer to the "LCD Display Mode" section in chapter 3 for details on how to view the Hyundai Accent tire pressure screen.
• A "Drive to display" message will appear for the first few minutes of driving after initial engine start up. If the tire pressure is not displayed after a few minutes of driving, check the tire pressures manually.
• The displayed tire pressure may differ slightly from values measured with a tire pressure gage due to temperature, sensor update timing, or gauge tolerances.
• You can change the tire pressure unit in the User Settings mode on the cluster to match your preference.

Tire Pressure Monitoring System

WARNING

Over-inflation or under-inflation can reduce tire life, adversely affect vehicle handling, and lead to sudden tire failure that may cause loss of vehicle control resulting in 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 placard or tire inflation pressure label. For best results on your Hyundai Accent, check pressures before driving or after the vehicle has been parked for several hours.

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. Using incorrect pressure can change how your Hyundai Accent rides, steers, and brakes.

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 Hyundai Accent vehicle handling and stopping ability, especially during emergency braking or sudden lane changes.

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 Hyundai Accent to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.

NOTICE

If any of the below happens, have the system checked by an authorized HYUNDAI dealer.

1. The Low Tire Pressure TPMS Malfunction Indicator does not illuminate for 3 seconds when the ignition switch is placed to the ON position or engine is running.

2. The TPMS Malfunction Indicator remains illuminated after blinking for approximately 1 minute.

3. The Low Tire Pressure LCD display remains illuminated

Low Tire Pressure Telltale

Low Tire Pressure LCD Display with Position Indicator

When the tire pressure monitoring system warning indicators are illuminated and the warning message is displayed on the cluster LCD display, one or more of your tires is significantly under-inflated. The LCD position indicator will indicate which tire is significantly under-inflated by illuminating the corresponding position light.

If any of your tire pressures are indicated as being low, immediately reduce your speed, avoid hard cornering, and anticipate increased stopping distances. You should stop and check your tires as soon as possible. Inflate the tires to the proper pressure as indicated on the vehicle’s placard or tire inflation pressure label located on the driver's side center pillar outer panel. This is especially important for Hyundai Accent highway driving, where heat build-up happens faster.

If you cannot reach a service station or if the tire cannot hold the newly added air, replace the low pressure tire with the spare tire.

The Low Tire Pressure LCD position indicator will remain on and the TPMS Malfunction Indicator may blink for one minute and then remain illuminated until you have the low pressure tire repaired and replaced on the vehicle.

NOTICE

The spare tire is not equipped with a tire pressure sensor.

CAUTION

In winter or cold weather, the Low Tire Pressure Telltale may be illuminated if the tire pressure was adjusted to the recommended tire inflation pressure in warm weather. It does not mean your TPMS is malfunctioning because the decreased temperature leads to a proportional lowering of tire pressure.

When you drive your vehicle from a warm area to a cold area or from a cold area to a warm area, or the outside temperature is greatly higher or lower, you should check the tire inflation pressure and adjust the tires to the recommended tire inflation pressure.

WARNING

Low pressure damage

Significantly low tire pressure makes the vehicle unstable and can contribute to loss of vehicle control and increased braking distances.

Continued driving on low pressure tires can cause the tires to overheat and fail. For Hyundai Accent safety, stop as soon as it is safe and correct the pressure.

TPMS Malfunction Indicator

The TPMS Malfunction Indicator will illuminate after it blinks for approximately one minute when there is a problem with the Tire Pressure Monitoring System. When this occurs, TPMS readings may be unavailable or inaccurate.

Have the system checked by an authorized HYUNDAI dealer as soon as possible to restore proper monitoring on your Hyundai Accent.

NOTICE

If there is a malfunction with the TPMS, the individual tire pressures in the cluster LCD display will not be available. Have the system checked by an authorized HYUNDAI dealer as soon as possible.

NOTICE

The TPMS Malfunction Indicator may illuminate after blinking for one minute if the vehicle is near electric power supply cables or radio transmitters such as police stations, government and public offices, broadcasting stations, military installations, airports, transmitting towers, etc.

Additionally, the TPMS Malfunction Indicator may illuminate if snow chains are used or electronic devices such as computers, chargers, remote starters, navigation, etc. This may interfere with normal operation of the TPMS. If the warning clears after leaving the area or removing the interference, continue to monitor your Hyundai Accent tire pressures and system behavior.

Changing a Tire with TPMS

If you have a flat tire, the Low Tire Pressure telltale and the LCD position indicator will come on. Have the flat tire repaired by an authorized HYUNDAI dealer as soon as possible, or replace the flat tire with the spare tire if you must continue driving. For Hyundai Accent safety, always move to a secure location off the roadway before inspecting the tire.

CAUTION

Do not use a puncture-repairing agent not approved by an authorized HYUNDAI dealer to repair and/or inflate a low pressure tire. Tire sealant not approved by a HYUNDAI dealer may damage the tire pressure sensor and could lead to incorrect TPMS readings on your Hyundai Accent.

The spare tire does not come with a tire pressure monitoring sensor. When the low pressure tire or the flat tire is replaced with the spare tire, the Low Tire Pressure LCD position indicator will remain on. Also, the TPMS Malfunction Indicator will illuminate after blinking for one minute if the vehicle is driven at a speed above 15.5 mph (25 km/h) for approximately 20 minutes. This is normal behavior because the Hyundai Accent TPMS cannot receive a sensor signal from the spare tire.

Once the original tire equipped with a tire pressure monitoring sensor is reinflated to the recommended pressure and reinstalled on the vehicle, the Low Tire Pressure LCD position indicator and TPMS Malfunction Indicator will go off within a few minutes of driving, as the system updates and confirms normal pressure.

If the indicators do not disappear after a few minutes, please visit an authorized HYUNDAI dealer. Continuing to drive with warnings active may reduce the benefits of Hyundai Accent tire pressure monitoring and could mask another issue.

Each wheel is equipped with a tire pressure sensor mounted inside the tire behind the valve stem (except for the spare tire). You must use TPMS-specific wheels. Have your tires serviced by an authorized HYUNDAI dealer to help protect the sensor and to ensure correct installation and sealing.

You may not be able to identify a tire with low pressure by simply looking at it. Always use a good quality tire pressure gage to measure the tire's inflation pressure. Please note that a tire that is hot (from being driven) will have a higher pressure measurement than a tire that is cold, so readings should be compared only under similar conditions.

A cold tire means the vehicle has been sitting for 3 hours and driven for less than 1 mile (1.6 km) in that 3 hour period. This is the best condition for checking Hyundai Accent tire inflation pressure accurately.

Allow the tire to cool before measuring the inflation pressure. Always be sure the tire is cold before inflating to the recommended pressure shown on the vehicle placard.

WARNING

• The TPMS cannot alert you to severe and sudden tire damage caused by external factors such as nails or road debris.
• If you feel any vehicle instability, immediately take your foot off the accelerator, apply the brakes gradually with light force, and slowly move to a safe position off the road. Turn on the hazard warning flasher if needed to warn other drivers.

WARNING

Tampering with, modifying, or disabling the Tire Pressure Monitoring System (TPMS) components may interfere with the system's ability to warn the driver of low tire pressure conditions and/or TPMS malfunctions. Tampering with, modifying, or disabling the Tire Pressure Monitoring System (TPMS) components may void the warranty for that portion of the vehicle. For reliable Hyundai Accent TPMS performance, always use approved parts and qualified service.
