•As the airbags deflate you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the nontoxic gas used for airbag
inflation. These airborne particles may irritate the skin,
eyes, nose, or throat. If you have skin or eye irritation,
rinse the area with cool water. For nose or throat
irritation, move to fresh air. If the irritation continues,
see your doctor. If these particles settle on your
clothing, follow the garment manufacturer’s instruc-
tions for cleaning.
•It is not advisable to drive your vehicle after the
airbags have deployed. If you are involved in another
collision, the airbags will not be in place to protect you.
WARNING!
Deployed airbags and seat belt pretensioners cannot
protect you in another collision. Have the airbags,
seat belt pretensioners, and seat belt retractor assem-
bly replaced by an authorized dealer as soon as
possible.
Enhanced Accident Response Feature
If the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. The hazard
lights will flash and the fuel will be cut off to the engine.
In addition, after the vehicle has stopped moving, the
interior lights will illuminate to aid visibility and remain
lit until the ignition switch is turned off.
NOTE:The interior lights can only be deactivated if the
key is removed from the ignition switch or the vehicle is
driven.
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Lights
Have someone observe the operation of all exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check the area under the vehicle after overnight parking
for fuel, coolant, oil or other fluid leaks. Also, if gasoline
fumes are detected, the cause should be located and
corrected immediately.
76 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

5. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system called OBD II that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the key is in
the ON position before engine start. If the bulb does not
come on when turning the key from OFF to ON, have the
condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations the vehicle will drive normally and will
not require towing.
The Malfunction Indicator Light flashes to alert you to
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced as soon as possible if this occurs.6. Airbag Warning Light
This light turns on and remains on for six to
eight seconds as a bulb check when the ignition
switch is first turned ON. If the light is not on
during starting, stays on, or turns on while
driving, have the system inspected by an authorized
dealer as soon as possible.
7. Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON position and may
stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.

12. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly, when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard
or tire inflation pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation alsoreduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or

NOTE:You must apply the brakes before shifting from
PARK.
22. Fuel Gauge
The pointer shows the level of fuel in the fuel tank when
the ignition switch is in the ON position.
23. Electronic Throttle Control (ETC) Warning Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected, the light will come on
while the engine is running. Cycle the ignition
key when the vehicle has completely stopped, and the
shift lever is placed into the PARK position. The light
should turn off. If the light remains lit with the engine
running, your vehicle will usually be drivable; however,
see your authorized dealer for service as soon as possible.
If the light is flashing when the engine is running,
immediate service is required and you may experience
reduced performance, an elevated/rough idle or enginestall and your vehicle may require towing. The light will
come on when the ignition is first turned on and remain
on briefly as a bulb check. If the light does not come on
during starting, have the system checked by an autho-
rized dealer.
24. Front Fog Light Indicator — If Equipped
This light shows the front fog lights are ON.
25. Charging System Light
This light shows the status of the electrical charging
system. The light should come on when the ignition
switch is first turned ON and remain on briefly as a bulb
check. If the light stays on or comes on while driving, turn
off some of the vehicle’s non-essential electrical devices or
increase engine speed (if at idle). If the charging system light
remains on, it means that the vehicle is experiencing a
problem with the charging system. Obtain SERVICE IMME-
DIATELY. See an authorized dealer.

26. Low Fuel Light
When the fuel level reaches approximately 2.3 U.S.
Gallons (8.7 Liters) this light will come on and
remain on until fuel is added. The Low Fuel
Warning Light may turn on and off again, especially
during and after hard braking, accelerations, or turns.
This occurs due to the shifting of the fuel in the tank.
Also, a single chime will sound.

(EVIC)
The Electronic Vehicle Information Center (EVIC) fea-
tures a driver-interactive display that is located in the
instrument cluster.The EVIC consists of the following:

Average Fuel Economy / Fuel Saver Mode (5.7L
Engine Only)
Shows the average fuel economy since the last reset.
When the fuel economy is reset, the display will read
“RESET” or show dashes for two seconds. Then, the
history information will be erased, and the averaging will
continue from the last fuel average reading before the
reset.
Vehicles with the 5.7L Multi-Displacement System (MDS)
are equipped with the FUEL SAVER MODE in the Trip
Functions of the EVIC. The “FUEL SAVER” message will
display above the average fuel economy in the EVIC
display. This message will appear whenever MDS allows
the engine to operate on four cylinders, which will vary
depending on driving habits and vehicle usage.

This feature allows you to monitor when the MDS
switches off the fuel on four of the eight cylinders and it
can be used to modify driving habits in order to increase
the time in which the fuel saver mode is active.
