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.
