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 94). 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 will not
respond immediately to the air added to
your tires.
It could 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
could 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
could decrease about
3 psi (21 kPa) for a
drop of 30°F (17°C) in ambient
temperature. This lower pressure value
could 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.
CHANGING A ROAD WHEEL WARNING:
If the tire pressure
monitor sensor becomes damaged it
may not function.
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, mount all road
wheels equipped with tire pressure
monitoring sensors on the vehicle. Note:
You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
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 to prevent damage to the tire
pressure monitoring system sensors.
See
Tire Pressure Monitoring System (page
304). Replace the spare tire with a road tire
as soon as possible. During repairing or
replacing of the flat tire, have an authorized
dealer inspect the tire pressure monitoring
system sensor for damage.

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, use it 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 originally came with your vehicle. If
the dissimilar spare tire or wheel is
damaged, replace it instead of repairing it.

Changing a Road Wheel Procedure WARNING: When one of the front
wheels is off the ground, the
transmission alone will not prevent the
vehicle from moving or slipping off the
jack, even if the transmission is in park
(P). WARNING:
To help prevent your
vehicle from moving when changing a
wheel, shift the transmission into park
(P), set the parking brake and use an
appropriate block or wheel chock to
secure the wheel diagonally opposite to
the wheel being changed. For example,
when changing the front left wheel,
place an appropriate block or wheel
chock on the right rear wheel. WARNING:
Do not work on your
vehicle when the jack is the only support.
If the vehicle slips off the jack, you or
someone else could be seriously injured. WARNING: Check that the vehicle
jack is not damaged or deformed and
the thread is lubricated and clean. WARNING:
Never place anything
between the vehicle jack and your
vehicle. WARNING:
Never place anything
between the vehicle jack and the ground. WARNING:
Do not attempt to
change a tire on the side of the vehicle
close to moving traffic. Pull far enough
off the road to avoid the danger of being
hit when operating the jack or changing
the wheel. WARNING:
Park your vehicle so
that you do not obstruct the flow of
traffic or place yourself in any danger and
set up a warning triangle. WARNING:
The jack supplied with
this vehicle is only intended for changing
wheels. Do not use the vehicle jack other
than when you are changing a wheel in
an emergency. WARNING:

11. Loosen each wheel lug nut one-half turn counterclockwise, but do not
remove them until you raise the
wheel off the ground.12. You can identify the vehicle jacking
points by the triangle markings on the
molding as shown. The triangle
marking may be on the side or the
underside of the molding. On vehicles
without moldings, a pair of arrows on
the metal flange pointing to the
jacking point between them identifies
the jacking points. The warning label
on the jack depicts the details. 13. Place the jack at the jacking point
next to the tire you are changing. Turn
the jack handle clockwise until the
wheel is completely off the ground.
14. Remove the lug nuts with the lug wrench.
15. Replace the flat tire with the spare tire, making sure the valve stem is
facing outward. Reinstall the lug nuts
until the wheel is snug against the
hub. Do not fully tighten the lug nuts
