Infiniti S51-D owner manual 4Starting and driving

.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. After the tire is 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.

.Tire pressure rises and falls depending on the heat caused by the vehicle’s 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 in low ambient temperature, check the tire pressure for all four tires.

.You can also check the pressure of all tires (except the spare tire) on the display screen. The order of the tire pressure figures displayed on the

5-4Starting and driving

screen does not correspond with the actual order of the tire position. See “Tire Pressure information” in the “4. Monitor, climate, audio, phone and voice recognition systems” section.

For additional information, see “Low tire pressure warning light” in the “2. Instru- ments and controls” section and “TIRE PRESSURE MONITORING SYSTEM (TPMS)” in the “6. In case of emergency” section.

WARNING

.If the low tire pressure warning light illuminates or LOW PRESSURE informa- tion is displayed on the monitor screen 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 under-inflated tires may permanently damage the tires and increase the likelihood of tire fail- ure. 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 the light still illuminates while driving after adjusting the tire pressure, a tire may be flat. If you have a flat tire, replace it with a spare tire as soon as possible. (See “FLAT TIRE” in the “6. In case of emergency” section for chan- ging a flat tire.)

.When a spare tire is mounted or a wheel is replaced, 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 INFINITI dealer as soon as possible for tire replacement and/or system resetting.

.Replacing tires with those not originally specified by INFINITI 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

.The TPMS may not function properly when the wheels are equipped with tire
