Nissan Altima Owners Manual: Tire Pressure Monitoring System (TPMS)

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 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 vehicles handling and stopping ability.

Please note that the TPMS is not a substitute for proper tire maintenance, and it is the drivers 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.

Additional information:

● The TPMS does not monitor the tire pressure of the spare tire.

● The TPMS will activate only when the vehicle is driven at speeds above 16 MPH (25 km/h). Also, this system may not detect a sudden drop in tire pressure (for example a flat tire while driving).

● The low tire pressure warning light does not automatically turn off when the tire pressure is adjusted on all 4 tires. After all 4 tires are inflated to the recommended pressure, the vehicle must be driven at speeds above 16 MPH (25 km/h) to activate the TPMS and turn off the low tire pressure warning light.

Use a tire pressure gauge to check the tire pressure.

● The Tire Pressure Low - Add Air warning appears in the vehicle information display when the low tire pressure warning light is illuminated and low tire pressure is detected.

The Tire Pressure Low - Add Air warning turns off when the low tire pressure warning light turns off.

● The Check Tire Pressure warning appears each time the ignition switch is placed in the ON position as long as the low tire pressure warning light remains illuminated.

● The Tire Pressure Low - Add Air warning does not appear if the low tire pressure warning light illuminates to indicate a TPMS malfunction.

● Tire pressure rises and falls depending on the heat caused by the vehicles operation and the outside temperature. Low outside temperature can lower the temperature of the air inside the tire which can cause a lower tire inflation pressure. This may cause the low tire pressure warning light to illuminate.

If the warning light illuminates, check the tire pressure for all four tires.

● The Tire and Loading Information label (also referred to as the vehicle placard or tire inflation pressure label) is located in the drivers door opening.

● You can also check the tire pressure of all tires (expect the spare) on the vehicle information display screen (if so equipped). The order of the tire pressure figures displayed on the screen corresponds with the actual order of the tire position.

For additional information, see Low tire pressure warning light in the Instruments and controls section, Tire Pressure Monitoring System (TPMS) in the In case of emergency section and Tire Pressure in the Maintenance and doit- yourself section.

WARNING

● Radio waves could adversely affect electric medical equipment. Those who use a pacemaker should contact the electric medical equipment manufacturer for the possible influences before use.

● If the low tire pressure warning light illuminates while driving, avoid sudden steering maneuvers or abrupt braking, reduce vehicle speed, pull off the road to a safe location and stop the vehicle as soon as possible. Driving with underinflated tires may permanently damage the tires and increase the likelihood of tire failure. Serious vehicle damage could occur and may lead to an accident and could result in serious personal injury.

Check the tire pressure for all four tires. Adjust the tire pressure to the recommended COLD tire pressure shown on the tire and loading information label to turn the low tire pressure warning light OFF. If you have a flat tire, replace it with a spare tire as soon as possible. (See Flat tire in the In case of emergency section for changing a flat tire.)
● When a spare tire is mounted or a wheel is replaced, tire pressure will not be indicated, the TPMS will not function and the low tire pressure warning light will flash for approximately 1 minute.

The light will remain on after 1 minute.

Contact your NISSAN dealer as soon as possible for tire replacement and/or system resetting.

● Replacing tires with those not originally specified by NISSAN could affect the proper operation of the TPMS.

● Do not inject any tire liquid or aerosol tire sealant into the tires, as this may cause a malfunction of the tire pressure sensors.

CAUTION

Do not place metalized film or any metal parts (antenna, etc.) on the windows. This may cause poor reception of the signals from the tire pressure sensors, and the TPMS will not function properly.

Some devices and transmitters may temporarily interfere with the operation of the TPMS and cause the low tire pressure warning light to illuminate.

Some examples are:

Facilities or electric devices using similar radio frequencies are near the vehicle.

If a transmitter set to similar frequencies is being used in or near the vehicle.

If a computer (or similar equipment) or a DC/AC converter is being used in or near the vehicle.

TPMS with Easy Fill Tire Alert

When adding air to an under-inflated tire, the TPMS with Easy Fill Tire Alert provides visual and audible signals outside the vehicle to help you inflate the tires to the recommended COLD tire pressure.

Vehicle set-up:

1. Park the vehicle in a safe and level place.

2. Apply the parking brake and place the shift lever to the P (Park) position.

3. Place the ignition switch to the ON position.

Do not start the engine.

Operation:

1. Add air to the tire.

2. After a few seconds, the hazard indicators will start flashing.

3. When the designated pressure is reached, the horn beeps once and the hazard indicators stop flashing.

4. Perform the above steps for each tire.

● If the tire is over-inflated more than approximately 4 psi (30 kPa), the horn beeps and the hazard indicators flash 3 times. To correct the pressure, push the core of the valve stem on the tire briefly to release pressure. When the pressure reaches the designated pressure, the horn beeps once.

● If the hazard indicator does not flash within approximately 15 seconds after starting to inflate the tire, it indicates that the Easy Fill Tire Alert is not operating.

● The TPMS will not activate the Easy Fill Tire Alert under the following conditions:

If there is interference from an external device or transmitter.

The air pressure from the inflation device is not sufficient to inflate the tire.

There is a malfunction in the TPMS system.

There is a malfunction in the horn or hazard indicators.

The identification code of the tires pressure sensor is not registered to the system.

The battery of the tire pressure sensor is low.

● If the Easy Fill Tire Alert does not operate due to TPMS interference, move the vehicle about 3 ft (1 m) backward or forward and try again.

If the Easy Fill Tire Alert is not working, use a tire pressure gauge.
