therefore it may take up to a minute for the light to turn off after you
have filled your tires to the recommended tire pressure.
•If your vehicle has been parked for over 15 minutes, the sensors go
into a low power mode to conserve battery life and therefore only
transmit about once an hour. If you inflate your tires under these
conditions, the light could take up to an hour to turn off after you
have filled your tires to the recommended tire pressure.
For these reasons, the low tire warning light is NOT a substitute for
using an accurate tire gauge when checking and filling your tires. The
best way to turn off the low tire warning light is to fill your tires to the
recommended tire pressure and drive your vehicle — the tire pressure
sensors in your wheels will update your vehicle with the updated tire
pressure when your vehicle reaches a speed of 20 mph (32 km/h) for at
least a minute.
How temperature affects your tire pressure
The Tire Pressure Monitoring System (TPMS) monitors tire pressure in
each pneumatic tire. The pressure in each tire is dependent upon several
factors, one of them being the contained air temperature (temperature of
the air inside the tire). As the contained air temperature increases, the
tire pressure also increases. 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. This increase in tire pressure
is due to an increase in the contained air temperature. Contained air
temperature is dependent upon several factors such as rate of tire
rotation, tire deflection, amount of braking, etc. In similar manner, the
tire pressure will decrease if the contained air temperature decreases.
For example, 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 cold pressure
indicated on your vehicles Safety Compliance Certification Label, and
activate the TPMS warning for low tire pressure. If the low 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. If all tires appear to be inflated,
carefully drive the vehicle to the nearest location where air can be added
to the tires. Turn the ignition to the “off” position. Inflate all the tires to
the recommended cold pressure.
The Tire Pressure Monitoring System complies with part 15 of the FCC
rules and with RS-210 of Industry Canada. Operation is subject to the
following two conditions: (1) This device may not cause harmful

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Your vehicle may be equipped with a conventional spare tire that is
different in one or more of the following: type, brand, size, speed rating
and tread design. If this is the case, this dissimilar spare tire is still rated
for your vehicle loads (GAWR and GVWR). Your vehicle may be equipped
with a spare wheel that may not match the road wheels and is not
equipped with a Tire Pressure Monitor System (TPMS) sensor.
The use of tire sealants may damage your tires. The use of tire
sealants may also damage your Tire Pressure Monitoring System.
