When Inflating Your Tires
WARNING: Do not use the tire
pressure displayed in the information
display as a tire pressure gauge. Failure
to follow this instruction could result in
personal injury or death.
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 about 2–4 psi (14–28 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
the 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.
Tire Pressure Monitoring System
Reset Procedure
Overview
You must carry out the system reset
procedure after each tire replacement or
adjustment of the tire pressures.
To maintain your vehicle load carrying
capability, your vehicle may require
different tire pressures in the front
compared to the rear. In these cases, the
system illuminates the warning lamp at
different pressures for the front and rear
tires.
If the tires are rotated, you need to reset
the system in order to relearn the positions
of the tire pressure sensors. The system
cannot tell which position a tire pressure
sensor is in, and assumes you have set the
tire pressures correctly.
Performing the Reset Procedure
1. Switch the ignition on.
2. Navigate to the tire monitor menu in
the information display. See
Information Messages (page 100).
3. Press and hold the OK button until a
confirmation message appears. If your
vehicle has a tire pressure monitoring
system reset button, press and hold
the button until a confirmation
message appears.
