•ACM (Airbag Control Module)
•AIRBAG Readiness Light
•Driver and Passenger Front Airbags
•Optional Driver and Passenger Side Airbags.
•Steering Wheel and Column
•Instrument Panel
•Interconnecting Wiring
•Crash Sensors
•Knee Impact Bolsters
The side airbag system, on vehicles so equipped, consists
of the following:
•AIRBAG Readiness Light
•Side Airbag in the Driver’s Seat
•Side Airbag in the Passenger’s Seat
•ACM (Airbag Control Module)
•SIACM (Side Impact Airbag Control Module)
•Interconnecting Wiring
How the Frontal Airbag System Works
•
The front airbag control module determines if a frontal
collision is severe enough to require the airbags to
inflate.
•The airbag control module will not detect side, roll
over, or rear collisions.
•The airbag control module also monitors the readiness
of the electronic parts of the system whenever the
ignition switch is in the START or RUN positions.
These include all of the items listed above except the
knee bolsters, the instrument panel, and the steering
wheel and column. If the key is in the OFF position, in
the ACC position, or not in the ignition, the airbags are
not on and will not inflate.
•The airbag control module also turns on the
AIRBAG light in the instrument panel for 6 to
8 seconds when the ignition is first turned on,

Tire Pressure Monitor System — If Equipped
The Tire Pressure Monitor (TPM) system uses wireless
technology to monitor tire pressure levels. Sensors,
mounted to each wheel as part of the valve stem transmit
tire pressure readings to a receiver located in the over-
head console.
The tire pressure is shown in the Electronic Vehicle
Information Center (EVIC) display. The TPM system
remains active even if it is not displayed in the EVIC.CAUTION!
The TPM system is designed to monitor your tire
pressure and will not function as a tire pressure
gauge while adjusting the pressure in your tires.
There will be a delay between the instant you adjust
the air pressure in a tire and when the system
updates the display.
NOTE:The TPM system can inform you about a low or
high tire pressure condition, but it does not replace
normal tire maintenance. The TPM system is not in-
tended to provide you with notification of rapid pressure
loss.
1. If any tire pressure has exceeded the low or high
pressure (refer to “Starting and Operating, Tires Sec-
tion”), the TPM system will display a message in the
EVIC and sound a chime. It will then go into the tire
pressure display screen and flash the pressure value of
the tire that is low or high. This will be displayed for the
rest of the ignition cycle, or until either the C/T, MENU,
STEP, or RESET button is pressed.

NOTE:This display will return 60 seconds after either
the C/T, MENU, STEP, or RESET button is pressed. If a
tire is low or high, you should correct your tire inflation
pressure as soon as possible and inspect all of your tires.
Refer to “Starting and Operating, Tires Section, Tire
Inflation Pressures” for more details. Once the low or
high tire pressure message has occurred, it will continue
to blink until the tire pressure is corrected.
2. If the spare tire pressure has exceeded the low or high
pressure allowed, the TPM system will display a message
in the EVIC for 60 seconds and sound a chime per every
ignition cycle.
NOTE:This message will return every ignition cycle,
until the tire pressures are corrected.
3. When the vehicle is moving and the EVIC cannot
receive a valid sensor signal from the tire pressure
sensors, the TIRE PRESSURE UNAVAILABLE message
will be displayed for 5 seconds along with a chime. The
display will then shift to the individual tire pressure
display screen and display dashes for the tire or tires that
are affected. Once the TIRE PRESSURE UNAVAILABLE
message has been displayed, and valid sensor signals arereceived, the EVIC will display the TIRE PRESSURE
NOW AVAILABLE message for 5 seconds along with a
chime. This is meant to inform you when the TPM system
has returned to it’s normal operation. This will occur
when valid tire pressure sensor messages have been
received from all 4 road tires. The TPM system function is
temporarily unavailable due to external electromagnetic
interference, such as electronic devices or nearby radio or
TV towers.
4. In addition to monitoring the vehicle tires, the TPM
system monitors faults within the system. When any
fault has been set, the TPM system will display TIRE
SENSOR BAD/MISSING. Be sure to inspect your tires for
proper inflation pressure. After you determine that your
tires are properly inflated, see your authorized dealer for
service to diagnose the problem with the TPM system.
5. If a road tire is replaced by the spare, the TPM system
will automatically detect that the tires have been
switched (after the ignition has been cycled) and display
SPARE SWAP DETECTED along with a chime. This
could take up to 10 minutes with vehicle speed above 25
mph (40 km/h).

NOTE:
As a safety feature, successful training of at least
one transmitter will erase all previously trained transmit-
ters.
When this feature is selected the driver can choose to
train up to four remote keyless entry transmitters. Press-
ing the STEP button when in this display will select
“YES” or “NO”. When “YES” is selected and the MENU
button is pressed; the EVIC will display “PRESS RE-
MOTE LOCK & UNLOCK THEN PRESS UNLOCK”,
followed by a chime to indicate the training sequence can

up to four transmitters; after each transmitter is trained a
chime will sound indicating that the training was suc-
cessful. If remote link to memory is “YES,” the firsttransmitter trained will be associated with memory set-
ting 1 and the second transmitter trained will be associ-
ated with memory setting 2. Additional transmitters will
not be associated with a memory setting. When you have
finished training the transmitters, press the MENU but-
ton again and the EVIC will display “TRAIN DONE, x
TRAINED”. (Where x = 1,2,3, or 4) If no transmitters are
trained within approximately 30 seconds the EVIC will
