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 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 overnight
with the outside temperature significantly lower than the daytime
temperature, the tire pressure may decrease approximately 3 psi
(21 kPa) for a drop of 30°F (17°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
light 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.
