How The Airbag System Works
•
A crash sensor in the occupant compartment deter-
mines if a frontal impact is severe enough to require
the airbag. The sensor will not detect side, roll over, or
rear impacts. The crash sensor is connected to the
diagnostic unit and to the airbag/inflator unit.
•The Diagnostic Unit monitors the readiness of the
electronic parts of the system whenever the ignition
switch is in the START or RUN position. These include
all of the items listed above except the knee bolster, the
instrument panel, and the steering wheel and column.
The Diagnostic Unit also turns on the AIRBAG light in
the instrument panel for 6 to 8 seconds when the
ignition is first turned on, then turns the light off. If it
detects a malfunction in any part of the system, it turns
on the light either momentarily or continuously.
•The Airbag/Inflator Units are in the center of the
steering wheel and in the instrument panel. The words
SRS/AIRBAG are embossed on the airbag covers.
WARNING!
Ignoring the AIRBAG light in your instrument panel
could mean you won’t have the airbags to protect
you in a collision. If the light does not come on, stays
on after you start the vehicle, or if it comes on as you
drive, have the airbag system checked right away.
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

All vehicle wheels and tires must be the same size and
type as the original equipment wheels and tires must be
properly inflated to produce accurate signals for the
computer.
WARNING!
Significant over or under inflation of tires, or mixing
sizes of front or rear tires or wheels on the vehicle
can lead to loss of braking effectiveness.
The Anti-Lock Brake System conducts a low-speed self-
test at about 12 mph (20 km/h). If you have your foot
lightly on the brake while this test is occurring, you may
feel slight pedal movement. The movement can be more
apparent on ice and snow. This is normal.The Anti-Lock Brake System pump motor runs during
the self-test at 12 mph (20 km/h) and during an ABS stop.
The pump motor makes a low humming noise during
operation, which is normal.
WARNING!
Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.
118 STARTING AND OPERATING

Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
Low Tire Pressure (LTP) System
Low Tire Indicator
The Low Tire indicator in the Liquid Crystal Display
(LCD) of the instrument cluster will flash slowly and a
single chime will sound to warn if tire pressure falls
below 20 psi (138 kpa). The indicator will flash more
rapidly and a continuous tone will sound to warn if tire
pressure falls below 14 psi (97 kpa). Seek repair as soon as
possible.
If the indicator stays on and one chime will sound, a
system failure has occurred. See your dealer for service.
Although the tires are designed with a“run flat”feature
that allows the vehicle to be driven about 50 miles (80km) at 55 m.p.h. (88 kph), immediate service should be
obtained if the Low Tire indicator is activated.
WARNING!
Do not exceed 55 m.p.h. (88 k.p.h.) if the LOW Tire
indicator in the instrument cluster is illuminated.
Vehicle handling and braking may be reduced. You
could have an accident and be severely or fatally
injured.
NOTE:The“run flat”feature eliminates the need for a
spare tire and jack. This vehicle is not equipped with
either a spare tire or jack.
STARTING AND OPERATING 139

the vehicle is not going to be driven in the next 3
weeks, follow the battery recharge procedure in the
Service Manual, then disconnect the battery at the
negative terminal or use the save feature described in
Maintaining your Vehicle section under the Mainte-
nance Procedures sub-section, within Maintenance-
Free Battery.
CAUTION!
Use care when disconnecting the remote positive
cable. It is connected to the battery and can short out
to any metal on the vehicle. Always tape or wrap the
exposed cable end to prevent electrical shorts.
•Disconnecting the battery causes the engine control
system to lose memory of some“learned”functions,
unless using the Battery Save feature described inMaintaining your Vehicle section under the Mainte-
nance Procedures sub-section, within Maintenance-
Free Battery. The engine may run rough when first
started after a battery disconnect until the control
module“relearns”these functions.
Check the battery every 4 to 6 weeks to ensure that the
voltage is above 12.40. Voltage will drop more rapidly
in hot temperatures. If battery voltage drops below
12.40, follow the battery recharge procedure in the
Service Manual.
•Check that the radiator coolant level of protection is to
at least -20°F (-29°C).
•Block the wheels. Do not apply the Parking Brake.
•Make sure that all tires are inflated to the optimum
pressure, (29 PSI).

•Cut blocks of plywood about the same size of the tires.
Cover each block with indoor/outdoor carpeting and
place them between the tires and concrete. This will
prevent tire flat spotting.
•For long term storage, remove the tires and put the
vehicle up on blocks. Stack the tires on plywood and
cover with a tarp to prevent flat spotting.
•Move the wiper blades away from the windshield.
NOTE:To help prevent the battery from discharging
during shorter periods of inactivity, perform the follow-
ing:
1. Make sure that the trunk, hood, doors, windows and
convertible top are completely closed.
2. Make sure that remote transmitter is operating and
that the battery is good.3. Make sure that the hood, trunk and door switches are
in adjustment. Perform the quick system check which
follows.
Use the remote transmitter to set the alarm. If the alarm
SET light comes on and flashes, the system is operating
properly. If not, there is a problem with a switch or the
system. See your dealer for service.REPLACEMENT BULBS
