(1) Low Tire Pressure Telltale/ TPMS Malfunction Indicator
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. (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.
✽ NOTICE
If the TPMS Low Tire Pressure Telltale does not illuminate for three seconds when the ignition switch is in the ON position or when the engine starts, or if it remains illuminated after coming on for approximately three seconds, take your vehicle to your nearest authorized HYUNDAI dealer and have the system checked.
Low Tire Pressure Telltale
(TPMS). The TPMS is not a substitute for manually checking tire pressure with a tire" title="Hyundai Tucson: Tire pressure monitoring system (TPMS)" border="0" src="images/4/page.h112.gif">
The TPMS is not a substitute for manually checking tire pressure with a tire pressure gauge. Changes in temperature affect tire pressure. See “Tires and Wheels” in chapter 7 for proper tire inflating and tire pressure measurement procedures.
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 door jamb. If you cannot reach a service station or if the tire cannot hold the newly added air, replace the low pressure tire with the compact spare tire.
The Low Tire Pressure Telltale will remain on and the TPMS Malfunction Indicator may blink for one minute and then remain illuminated if the vehicle is driven approximately 20 minutes at speed above 15.5 mph (25 km/h).
✽ NOTICE
The compact 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
- 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.
TPMS Malfunction Indicator
(TPMS). The TPMS Malfunction Indicator comes on after it blinks for approximately one" title="Hyundai Tucson: Tire pressure monitoring system (TPMS)" border="0" src="images/4/page.h113.gif">
The TPMS Malfunction Indicator comes on after it blinks for approximately one minute when there is a problem with the Tire Pressure Monitoring System.
Have the system checked by an authorized HYUNDAI dealer as soon as possible to determine the cause of the problem.
✽ 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.
This device complies with Part 15 of the FCC rules.
Operation is subject to the following two conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received, including interference that may cause undesired
Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
Tampering with, modifying, or disabling the TPMS components may interfere with the system’s ability to function and may void the warranty for that portion of the vehicle.
Changing a Tire with TPMS
If you have a flat tire, the Low Tire Pressure Telltale will illuminate. If you believe you have a flat tire or feel any vehicle instability, take your foot off the accelerator pedal and let the vehicle slow down while driving straight ahead. Do not apply the brakes immediately or attempt to pull off the road as this may cause a loss of control resulting in an accident. When the vehicle has slowed to such a speed that it is safe to do so, brake carefully and pull off the road. Drive off the road as far as possible and park on firm, level ground. If you are on a divided highway, do not park in the median area between the two traffic lanes. Replace the flat tire with the compact spare tire.
CAUTION
To prevent damaging your tire pressure sensor, never use a puncture-repairing agents or tire sealants to repair and/or inflate a low pressure tire. If used, you will have to replace the tire pressure sensor.
The compact spare tire is not equipped 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 Telltale will remain on. Also, the TPMS Malfunction Indicator will illuminate after blinking for one minute if the vehicle is driven at speed above 15.5 mph (25 km/h) for approximately 20 minutes.
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 Telltale and TPMS Malfunction Indicator will go off within a few minutes.
If the indicators do not extinguish after a few minutes, please visit an authorized HYUNDAI dealer.
Each wheel is equipped with a tire pressure sensor mounted inside the tire behind the valve stem (except for the compact spare). You must use TPMS specific wheels. It is recommended that you always have your tires serviced by an authorized HYUNDAI dealer as soon as possible.
