Spare tire in

use

Your temporary spare tire is in

use. Repair the damaged road

wheel and re-mount it on the

vehicle to restore system

functionality. For a description of

how the system functions under

these conditions, refer to When

installed in this section.

TPMS

malfunction

If your tires are properly inflated

and your spare tire is not in use

and the TPMS warning light still

flashes, have the system inspected

by your authorized dealer.

When inflating your tires

When putting air into your tires (such as at a gas station or in your

garage), the Tire Pressure Monitoring System may not respond

immediately to the air added to your tires.

It may take up to two minutes of driving over 20 mph (32 km/h) for the

light to turn OFF after you have filled your tires to the recommended

inflation pressure.

How temperature affects your tire pressure

The Tire Pressure Monitoring System (TPMS) monitors tire pressure in

each pneumatic tire. While driving in a normal manner, a typical

passenger tire inflation pressure may increase approximately 2 to 4 psi

(14 to 28 kPa) from a cold start situation. If the vehicle is stationary

over night with the outside temperature significantly lower than the

daytime temperature, the tire pressure may decrease approximately 3 psi

(20.7 kPa) for a drop of 30° F (16.6°C) in ambient temperature. This

lower pressure value may be detected by the TPMS as being significantly

lower than the recommended inflation pressure and activate the TPMS

warning for low tire pressure. If the low tire pressure warning light is

ON, visually check each tire to verify that no tire is flat. (If one or more

tires are flat, repair as necessary.) Check air pressure in the road tires. If

any tire is under-inflated, carefully drive the vehicle to the nearest

location where air can be added to the tires. Inflate all the tires to the

recommended inflation pressure.
