Passenger Safety Belt Reminder
Light
Several seconds after the key is turned to RUN or
START, a chime will sound for several seconds to
remind the front passenger to buckle their safety belt.
This would only occur if the passenger airbag is
enabled. SeePassenger Sensing System on page 1-63
for more information. The passenger safety belt light
will also come on and stay on for several seconds, then
it will ash for several more.
This chime and light will be
repeated if the passenger
remains unbuckled and
the vehicle is in motion.
If the passenger’s safety belt is buckled, neither the
chime nor the light will come on.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, which shows the airbag symbol. The system
checks the airbag’s electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the airbag sensors, the
airbag modules, the wiring and the diagnostic module.
For more information on the airbag system, see
Airbag System on page 1-52.
This light will come on
when you start your
vehicle, and it will ash for
a few seconds. Then the
light should go out.
This means the system
is ready.
If the airbag readiness light stays on after you start the
vehicle or comes on when you are driving, your
airbag system may not work properly. Have your vehicle
serviced right away.

Remove the valve cap from the tire valve stem. Press
the tire gage rmly onto the valve to get a pressure
measurement. If the cold tire ination pressure matches
the recommended pressure on the Tire and Loading
Information label, no further adjustment is necessary. If
the ination pressure is low, add air until you reach
the recommended amount.
If you overll the tire, release air by pushing on the
metal stem in the center of the tire valve. Re-check the
tire pressure with the tire gage.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and
moisture.
Check Tire Pressure System
The Check Tire Pressure System is designed to alert
the driver when there is a large change in the air
pressure of one tire. The system learns the air pressure
at each tire throughout the operating speed range of
the vehicle, and compares tire rotational speeds using
the Anti-lock Brake System’s wheel speed sensors.
The Check Tire Pressure System will not alert you
before you drive the vehicle that a tire is low or at. You
must begin driving the vehicle before the system will
work properly.The CHECK TIRE PRESSURE warning message, on
the Driver Information Center (DIC), and the tire
pressure warning light, on the instrument panel cluster,
will come on if the system detects a pressure
difference in one of the four tires installed on the
vehicle. For additional information and details about the
DIC operation and displays seeDIC Controls and
Displays on page 3-50. An example of the tire pressure
warning light is shown underTire Pressure Light on
page 3-44.
The Check Tire Pressure System may not warn you of
a tire pressure condition if:
More than one tire is low.
The vehicle is moving faster than
65 mph (105 km/h).
The system is not yet calibrated.
The tire treadwear is uneven.
The compact spare tire is installed.
Tire chains are being used.
The vehicle is being driven on a rough or
frozen road.
If the anti-lock brake system warning light comes on,
the check tire pressure system may not be working
properly. See your dealer for service. Also, see
Anti-Lock Brake System Warning Light on page 3-41.
