Tire Pressure Monitoring System (TPMS) with Tire Inflation Indicator
A Flat Tire Visit Dealer or Tire Pressure Low —
Add Air warning message will appear in the vehicle
information display
1 and the low tire pressure
warning light 2 will illuminate when one or more
tires are low in pressure and air is needed.
• The tire pressures should be checked when
the tires are cold. The tires are considered cold
after the vehicle has been parked for 3 hours
or more or driven less than 1 mi (1.6 km) at
moderate speeds.

When adding air to an under-inflated tire, the TPMS
with Tire Inflation Indicator provides visual and
audible signals to help you inflate the tire to the recommended COLD tire pressure.
To use the tire inflation indicator:
1. Move the shift lever to the P (PARK) position and apply the parking brake.
2. Place the ignition switch in the ON position. Do not start the engine.
3. Add air to the under-inflated tire, and within a few seconds, the hazard warning lights will
start flashing.
4. When the designated tire pressure is reached, the horn will beep once and the hazard
warning flashers will stop flashing.
5. Repeat this procedure for any additional under-inflated tires.

After tire pressures are adjusted, drive the vehicle at speeds above 16 mph (25 km/h). The
Flat Tire Visit Dealer or Tire Pressure Low — Add Air warning message and low tire pressure
warning light will extinguish.

When the low tire pressure warning light flashes for 1 minute and then remains on, the
TPMS is not functioning properly. Have the system checked by an INFINITI retailer.

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, check the tire pressure
in your tires.
• Check the tire pressure (including the spare tire) often and always prior to long
distance trips.
