Understanding Your Tire Pressure
Monitoring System
The tire pressure monitoring system
measures pressure in your road tires and
sends the tire pressure readings to your
vehicle. You can view the tire pressure
readings through the information display.
See General Information (page 112). The
low tire pressure warning light will turn on
if the tire pressure is significantly low. Once
the light is illuminated, your tires are
under-inflated and need to be inflated to
the manufacturer
’s recommended tire
pressure. Even if the light turns on and a
short time later turns off, your tire pressure
still needs to be checked. When Your Temporary Spare Tire is
Installed
When one of your road tires needs to be
replaced with the temporary spare, the
system will continue to identify an issue to
remind you that the damaged road wheel
and tire assembly needs to be repaired and
put back on your vehicle.
To restore the full function of the tire
pressure monitoring system, have the
damaged road wheel and tire assembly
repaired and remounted on your vehicle.
When You Believe Your System is Not
Operating Properly
The main function of the tire pressure
monitoring system is to warn you when
your tires need air. It can also warn you in
the event the system is no longer capable
of functioning as intended. See the
following chart for information concerning
your tire pressure monitoring system:

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 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 equipped on
these vehicles is designed to 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.

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: If the tire pressure
monitor sensor becomes damaged it
may not function.
Note: You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
Note: The tire pressure monitoring system
indicator light illuminates when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle.
If you get a flat tire when 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.
Have a flat serviced by an authorized
dealer in order to prevent damage to the
tire pressure monitoring system sensors.
See
Tire Pressure Monitoring System
(page 370). Replace the spare tire with a
road tire as soon as possible. During
repairing or replacing of the flat tire, have
the authorized dealer inspect the tire
pressure monitoring system sensor for
damage. Dissimilar Spare Wheel and Tire
Assembly Information WARNING:
Failure to follow these
guidelines could result in an increased
risk of loss of vehicle control, injury or
death.
If you have a dissimilar spare wheel and
tire, then it is intended for temporary use
only. This means that if you need to use it,
you should replace it as soon as possible
with a road wheel and tire assembly that
is the same size and type as the road tires
and wheels that were originally provided
by us. If the dissimilar spare tire or wheel
is damaged, you should replace it rather
than repair it.
A dissimilar spare wheel and tire assembly
is defined as a spare wheel and tire
assembly that is different in brand, size or
appearance from the road tires and wheels
and can be one of three types:
1. T-type mini-spare:
This spare tire
begins with the letter T for tire size and
may have Temporary Use Only molded in
the sidewall.
2. Full-size dissimilar spare with label
on wheel:
This spare tire has a label on
the wheel that states: THIS WHEEL AND
TIRE ASSEMBLY FOR TEMPORARY USE
ONLY.
When driving with one of the dissimilar
spare tires listed above, do not:
• Exceed
50 mph (80 km/h).
• Load the vehicle beyond maximum
vehicle load rating listed on the Safety
Compliance Label.
• Tow a trailer.
• Use snow chains on the end of the
vehicle with the dissimilar spare tire.
• Use more than one dissimilar spare tire
at a time.
