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 about 3 psi (21
kPa) for a drop of 30°F (17°C) in ambient
temperature. This lower pressure value
may be detected by the tire pressure
monitoring system as being significantly
lower than the recommended inflation
pressure and activate the system 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.
USING SNOW CHAINS
WARNING
If you choose to install snow tires on
your vehicle, they must be the same
size, construction, and load range as
the original tires listed on the tire placard,
and they must be installed on all four
wheels. Mixing tires of different size or
construction on your vehicle can adversely
affect your vehicle's handling and braking,
and may lead to loss of vehicle control.
Do not use snow chains or cables on this
vehicle as they may cause damage to your
vehicle which may lead to loss of vehicle
control.
Snow chains or cables have not been
approved for use on your vehicle.
The original equipment tires on your vehicle
may have an all-weather tread design to
provide traction, handling, and braking
performance in year-round driving. You
may install snow tires for improved traction
when driving in areas with sustained
periods of snow or icy driving conditions
