How Temperature Affects Your Tire
Pressure
The tire pressure monitoring system
monitors tire pressure in each pneumatic
tire. When 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 WARNING:
To determine the
required pressure(s) for your vehicle, see
the Safety Compliance Certification
Label (on the door hinge pillar,
door-latch post or the door edge that
meets the door-latch post, next to the
driver seat) or the Tire Label on the
B-Pillar or the edge of the driver door.
Note: You need to perform the tire pressure
monitoring system reset procedure after
each tire rotation. To provide the vehicle's load carrying
capability, some vehicles require different
recommended tire pressures in the front
tires as compared to the rear tires. The tire
pressure monitoring system on these
vehicles illuminate the low tire pressure
warning light at two different pressures:
one for the front tires and one for the rear
tires.
Since tires need to be rotated to provide
consistent performance and maximum tire
life, the tire pressure monitoring system
needs to know when the tires are rotated
to determine which set of tires are on the
front and which are on the rear. With this
information, the system can detect and
properly warn of low tire pressures.
System reset tips:
•
To reduce the chances of interference
from another vehicle, perform the
system reset procedure at least
3 ft
(1 m) away from another vehicle
undergoing the system reset procedure
at the same time.
• Do not wait more than two minutes
between resetting each tire sensor or
the system can time-out and you have
to repeat the entire procedure on all
four wheels.
• A double horn sounds indicating the
need to repeat the procedure.
Performing the System Reset Procedure
- Single Rear Wheel
Read the entire procedure before
attempting.
1. Drive the vehicle above
20 mph
(32 km/h) for at least two minutes,
then park in a safe location where you
can easily get to all four tires and have
access to an air pump.
2. Place the ignition in the off position and
keep the key in the ignition.

3. Cycle the ignition to the on position
with the engine off.
4. Turn the hazard flashers on then off three times. You must accomplish this
within 10 seconds. If you successfully
enter the reset mode, the horn sounds
once, the system indicator flashes and
a message shows in the information
display. If this does not occur, please
try again starting at step 2. If after
repeated attempts to enter the reset
mode, the horn does not sound, the
system indicator does not flash and no
message shows in the information
display, have the system checked as
soon as possible.
5. Train the tire pressure monitoring system sensors in the tires using the
following system reset sequence
starting with the left front tire in the
following clockwise order: Left front -
driver side front tire, Right front -
passenger side front tire, Right rear -
passenger side rear tire, Left rear -
driver side rear tire.
6. Remove the valve cap from the valve stem on the left front tire. Decrease the
air pressure until the horn sounds.
Note: The single horn tone confirms that
the sensor identification code has been
learned by the module for this position. If
you hear a double horn, the reset procedure
was unsuccessful, and you must repeat it.
7. Remove the valve cap from the valve stem on the right front tire. Decrease
the air pressure until the horn sounds.
8. Remove the valve cap from the valve stem on the right rear tire. Decrease the
air pressure until the horn sounds. 9. Remove the valve cap from the valve
stem on the left rear tire. Decrease the
air pressure until the horn sounds.
Training is complete after the horn
sounds for the last tire trained, driver
side rear tire, the system indicator
stops flashing, and a message shows
in the information display.
10. Turn the ignition off. If you hear two short tones, the reset procedure was
unsuccessful and you must repeat it.
If you hear two short beeps when the
ignition is off after repeating the
procedure, have the system checked
as soon as possible
11. Set all four tires to the recommended
air pressure as indicated on the
Safety Compliance Certification
Label, affixed to either the door hinge
pillar, door-latch post, or the door
edge that meets the door-latch post,
next to the driver seating position or
Tire Label located on the B-Pillar or
the edge of the driver door.
CHANGING A ROAD WHEEL WARNING: To determine the
required pressure(s) for your vehicle, see
the Safety Compliance Certification
Label (on the door hinge pillar,
door-latch post or the door edge that
meets the door-latch post, next to the
driver seat) or the Tire Label on the
B-Pillar or the edge of the driver door.
Note: You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
