Tire Pressure Monitoring System (TPMS)

Suzuki SX4 / Suzuki SX4 Owners Manual / Operating Your Vehicle / Tire Pressure Monitoring System (TPMS)

The tire pressure monitoring system is designed to alert you when one or more of the tires on your vehicle is significantly under-inflated. A Tire Pressure Monitoring System (TPMS) sensor containing a unique identification code is mounted on each wheel. The TPMS sensors transmit tire pressure signals to a central receiver which relays the information to a tire pressure monitoring system controller. When the inflation pressure of one or more tires indicates significant under-inflation, the low tire pressure warning light shown below comes on.

WARNING:
WARNING:
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 underinflated 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.

WARNING:
WARNING:
The tire pressure monitoring system is not a substitute for regular tire pressure inspections. Check tire inflation pressures monthly when cold and set to the recommended inflation pressure as specified on the vehicle’s tire information placard and in the owner’s manual. Refer to “Tires” in the “INSPECTION AND MAINTENANCE” section.

WARNING:
WARNING:
If the low tire pressure warning light does not come on when the ignition is turned to the “ON” position, or comes on and blinks while driving there may be a problem with the tire pressure monitoring system. Have your vehicle inspected by an authorized SUZUKI dealer. Even if the light turns off after blinking, indicating that the monitoring system has recovered, make sure to have an authorized SUZUKI dealer check the system.

WARNING:
WARNING:
The load rating of your tires is reduced at lower inflation pressures.

If your tires become even moderately under-inflated, the vehicle load may exceed the load rating of the tires, which can lead to tire failure. The low tire pressure warning light will not alert you of this condition. The warning light will only come on when one or more of your tires become significantly under-inflated. Check and adjust your tire inflation pressure at least once a month. Refer to “Tires” in the “INSPECTION AND MAINTENANCE” section.

WARNING:
WARNING:
If the low tire pressure warning light comes on and stays on, reduce your speed and avoid abrupt steering and braking. Stop in a safe place as soon as possible and check your tires.

• If you have a flat tire, replace it with the spare tire. Refer to “Jacking Instructions” in the “EMERGENCY SERVICE” section. Refer to “Replacing Tires and/or Wheels” for instructions on how to restore normal operation of the tire pressure monitoring system after you have had a flat tire.

• If one or more of your tires is under-inflated adjust the inflation pressure in all of your tires to the recommended inflation pressure as soon as possible.

Be aware that driving on a significantly under-inflated tire can cause the tire to overheat and can lead to tire failure, and may affect steering control and brake effectiveness. This could lead to an accident, resulting in severe injury or death.

The low tire pressure warning light can come on due to normal causes such as natural air leaks and pressure changes caused by changes in temperature or atmospheric pressure. Adjusting the air pressure in the tires to the pressure shown on the tire information placard should cause the low tire pressure warning light to turn off.

If the light turns on again shortly after adjusting the pressure in your tires, you may have a flat tire. If you have a flat tire, replace it with the spare tire. Refer to “Jacking Instructions” in the “EMERGENCY SERVICE” section. Refer to “Replacing Tires and/or Wheels” for instructions on how to restore normal operation of the tire pressure monitoring system after you have had a flat tire.

NOTE:
• When the tire inflation pressure is adjusted in high altitude areas, the low tire pressure light may not turn off even after tire inflation pressure adjustment.

In this case, adjust the inflation pressure to a slightly higher pressure than is shown on the tire information placard.

• The low tire pressure warning light may turn off temporarily after coming on. This could be due to surface temperature increases after long distance driving or traveling to a high temperature area.

Even if the tire pressure warning light turns off after coming on, make sure to check the inflation pressure of all tires.

• To reduce the chance that the low tire pressure warning light will come on due to normal changes in temperature and atmospheric pressure, it is important to check and adjust the tire pressures when the tires are cold. Tires that appear to be at the specified pressure when checked after driving, when the tires are warm, could have pressure below the specification when the tires cool down. Also, tires that are inflated to the specified pressure in a warm garage may have pressure below the specification when the vehicle is driven outside in very cold temperature. If you adjust the tire pressure in a garage that is warmer than the outside temperature, you should add 1 psi to the recommended cold tire inflation pressure for every 10°F difference between garage temperature and outside temperature.

For tire inflation pressure information, refer to “Tire Inflation Pressure” in the “INSPECTION AND MAINTENANCE” section.

TPMS Malfunction Indicator

WARNING:
WARNING:
Your vehicle also has been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly.

WARNING:
WARNING:
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 you turn off the engine, however, the malfunction indicator resets. It takes about ten minutes after restarting the engine for the malfunction to be detected again and for the light to start flashing.

WARNING:
WARNING:
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.

CAUTION:
• The tire pressure sensors can be damaged by the installation or removal of tires. When tires must be repaired or replaced, we highly recommend that you have them repaired or replaced by an authorized SUZUKI dealer.

• Do not use liquid sealants for a flat tire as air pressure sensors can be damaged.

• If the low tire pressure warning light comes on frequently, there may be something wrong with one of the tires or with the monitoring system. Have your vehicle inspected by an authorized SUZUKI dealer.

TPMS Limitations

The tire pressure monitoring system may not function properly under certain circumstances.

In the following situations, the low tire pressure warning light may come on and remain on or may blink.

• When you replace a flat tire with the spare tire.

• When you include the spare tire during a tire rotation.

• When the TPMS sensor is damaged during a tire replacement or liquid sealants are used to repair a flat tire.

• When the TPMS sensor’s electronic signal is disturbed in one of the following ways:
– Electric devices or facilities using similar radio wave frequencies are nearby.

– A lot of snow or ice covers the vehicle, in particular, around the wheels or wheel housings.

– Snow tires or tire chains are used.

• When you use non-genuine SUZUKI wheels or tires.

Replacing Tires and/or Wheels

If you get a flat tire, Suzuki recommends that you have an authorized SUZUKI dealer mount a new tire on the wheel that had the flat tire, and reinstall this tire on the vehicle in place of the spare. The TPMS is already set up to recognize the ID code of the original wheel, and normal TPMS operation will be restored.

If you need to replace original wheels on your vehicle, your dealer must make sure that TPMS sensors are installed in the new wheels and must set up the TPMS to recognize the new sensors.

NOTE:
A TPMS sensor is not installed in the spare tire. You should use the spare tire only in an emergency situation, and should replace the spare tire as soon as possible to restore normal TPMS operation.

WARNING:
WARNING:
Only use tires and wheels recommended by SUZUKI as standard or optional equipment for your vehicle.

Use of tires or wheels not recommended by SUZUKI can result in
TPMS failure. Refer to “Tires” in the “INSPECTION AND MAINTENANCE” section for additional information.
