124 SAFETY
Front Air Bag Operation
Front Air Bags are designed to provide additional protection
by supplementing the seat belts. Front air bags are not
expected to reduce the risk of injury in rear, side, or rollover
collisions. The front air bags will not deploy in all frontal
collisions, including some that may produce substantial
vehicle damage — for example, some pole collisions, truck
underrides, and angle offset collisions.
On the other hand, depending on the type and location of
impact, front air bags may deploy in crashes with little
vehicle front-end damage but that produce a severe initial
deceleration.
Because air bag sensors measure vehicle deceleration over
time, vehicle speed and damage by themselves are not good
indicators of whether or not an air bag should have
deployed.
Seat belts are necessary for your protection in all collisions,
and also are needed to help keep you in position, away from
an inflating air bag.When the ORC detects a collision requiring the front air bags,
it signals the inflator units. A large quantity of non-toxic gas
is generated to inflate the front air bags.
The steering wheel hub trim cover and the upper passenger
side of the instrument panel separate and fold out of the way
as the air bags inflate to their full size. The front air bags fully
inflate in less time than it takes to blink your eyes. The front
air bags then quickly deflate while helping to restrain the
driver and front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the driver
and front passenger, and position the front occupants for
improved interaction with the front air bags.
WARNING!
• Do not drill, cut, or tamper with the knee impact bolsters in any way.
• Do not mount any accessories to the knee impact bolsters such as alarm lights, stereos, citizen band
radios, etc.

SAFETY 129
Rollover Events
Side Air Bags and seat belt pretensioners are designed to
activate in certain rollover events. The Occupant Restraint
Controller (ORC) determines whether deployment in a
particular rollover event is appropriate, based on the
severity and type of collision. Vehicle damage by itself is not
a good indicator of whether or not Side Air Bags and seat belt
pretensioners should have deployed.
The Side Air Bags and seat belt pretensioners will not deploy
in all rollover events. The rollover sensing system deter-
mines if a rollover event may be in progress and whether
deployment is appropriate. In the event the vehicle experi -
ences a rollover or near rollover event, and deployment is
appropriate, the rollover sensing system will deploy the side
air bags and seat belt pretensioners on both sides of the
vehicle.
The SABICs may help reduce the risk of partial or complete
ejection of vehicle occupants through side windows in
certain rollover or side impact events. Air Bag System Components

Enhanced Accident Response System Reset Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be changed
from ignition AVV/START or MAR/RUN to ignition
STOP/OFF. Carefully check the vehicle for fuel leaks in the
engine compartment and on the ground near the engine
compartment and fuel tank before resetting the system and
starting the engine.
Maintaining Your Air Bag System
WARNING!
• Modifications to any part of the air bag system could cause it to fail when you need it. You could be injured
if the air bag system is not there to protect you. Do not
modify the components or wiring, including adding
any kind of badges or stickers to the steering wheel hub
trim cover or the upper passenger side of the instru -
ment panel. Do not modify the front bumper, vehicle
body structure, or add aftermarket side steps or
running boards.
• It is dangerous to try to repair any part of the air bag system yourself. Be sure to tell anyone who works on
your vehicle that it has an air bag system.
• Do not attempt to modify any part of your air bag system. The air bag may inflate accidentally or may not
function properly if modifications are made. Take your
vehicle to an authorized dealer for any air bag system
service. If your seat, including your trim cover and
cushion, needs to be serviced in any way (including
removal or loosening/tightening of seat attachment
bolts), take the vehicle to an authorized dealer. Only
manufacturer approved seat accessories may be used. If
it is necessary to modify the air bag system for persons
with disabilities, contact an authorized dealer.

156 SAFETY
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts and
cracks. Inspect sidewalls for cuts, cracks, and bulges. Check
the wheel bolts for tightness. Check the tires (including
spare) for proper cold inflation pressure.
Lights

Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn signal
and high beam indicator lights on the instrument panel.

Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline fumes
are detected or if fuel, or brake fluid leaks are suspected, the
cause should be located and corrected immediately.
• NEVER place any objects under the floor mat (e.g.,
towels, keys, etc.). These objects could change the posi -
tion of the floor mat and may cause interference with
the accelerator, brake, or clutch pedals.
• If the vehicle carpet has been removed and re-installed, always properly attach carpet to the floor and check the
floor mat fasteners are secure to the vehicle carpet.
Fully depress each pedal to check for interference with
the accelerator, brake, or clutch pedals then re-install
the floor mats.
• It is recommended to only use mild soap and water to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners by
lightly pulling mat.

162 STARTING AND OPERATING
(Continued)
NOTE:
• When the parking brake is applied and the automatictransmission is placed in gear, the “Brake Warning Light”
will flash. If vehicle speed is detected, a chime will sound
to alert the driver. Fully release the parking brake before
attempting to move the vehicle.
• This light only shows that the parking brake is applied. It does not show the degree of brake application.
When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away from
the curb on an uphill grade. For vehicles equipped with an
automatic transmission, apply the parking brake before
placing the gear selector in PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the gear selector out of PARK. The parking brake
should always be applied whenever the driver is not in the
vehicle.
WARNING!
• When exiting the vehicle, always remove the key fob from the ignition and lock your vehicle.
• Never leave children alone in a vehicle, or with access to an unlocked vehicle.

• Allowing children to be in a vehicle unattended is dangerousfor a number of reasons. A child or others could be seriously
or fatally injured. Children should be warned not to touch
the parking brake, brake pedal or the gear selector.

• Do not leave the key fob in or near the vehicle, or in a location accessible to children. A child could operate
power windows, other controls, or move the vehicle.
• Be sure the parking brake is fully disengaged before driving; failure to do so can lead to brake failure and a
collision.
• Always fully apply the parking brake when leaving your vehicle or it may roll and cause damage or injury.
Also, be certain to leave an automatic transmission in
PARK, a manual transmission in REVERSE or first
gear. Failure to do so may cause the vehicle to roll and
cause damage or injury.
CAUTION!
If the Brake System Warning Light remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an
authorized dealer immediately.

166 STARTING AND OPERATING
(Continued)
PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range. Never
attempt to use PARK while the vehicle is in motion. Apply
the parking brake when exiting the vehicle in this range.
When parking on a level surface, you may shift the transmis-
sion into PARK first, and then apply the parking brake.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the gear selector out of PARK. As an added precaution,
turn the front wheels toward the curb on a downhill grade
and away from the curb on an uphill grade.
When exiting the vehicle, always:
• Apply the parking brake,
• Shift the transmission into PARK,
• Turn the engine OFF, and
• Remove the ignition key.WARNING!
• Never use the PARK position as a substitute for the parking brake. Always apply the parking brake fully
when exiting the vehicle to guard against vehicle move -
ment and possible injury or damage.
• Your vehicle could move and injure you and others if it is not in PARK. Check by trying to move the gear
selector out of PARK with the brake pedal released.
Make sure the transmission is in PARK before exiting
the vehicle.
• It is dangerous to shift out of PARK or NEUTRAL if the engine speed is higher than idle speed. If your foot is
not firmly pressing the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You could lose
control of the vehicle and hit someone or something.
Only shift into gear when the engine is idling normally
and your foot is firmly pressing the brake pedal.

170 STARTING AND OPERATING
Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle. A
clutch within the torque converter engages automatically at
calibrated speeds. This may result in a slightly different
feeling or response during normal operation in the upper
gears. When the vehicle speed drops or during some acceler-
ations, the clutch automatically disengages.
NOTE:
The torque converter clutch will not engage until the trans -
mission fluid is warm [usually after 1 to 3 miles (2 to 5 km)
of driving]. Because the engine speed is higher when the
torque converter clutch is not engaged, it may seem as if the
transmission is not shifting properly when cold. This is
normal. The torque converter clutch will function normally
once the transmission is sufficiently warm.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear. For example, if you
set the transmission gear limit to 5 (fifth gear), the transmis -
sion will not shift above fifth gear, but will shift through the
lower gears normally. You can switch between DRIVE and ERS mode at any
vehicle speed. When the gear selector is in the DRIVE posi
-
tion, the transmission will operate automatically, shifting
between all available gears.
Moving the gear selector to the ERS position (beside DRIVE)
will activate ERS mode, display the current gear in the
instrument cluster, and set that gear as the top available gear.
Once in ERS mode, moving the gear selector forward (-) or
rearward (+) will change the top available gear, which will
be displayed in the instrument cluster.
To exit ERS mode, simply return the gear selector to the
DRIVE position.
NOTE:
To select the proper gear position for maximum deceleration
(engine braking), move the gear selector into the ERS posi -
tion, then simply press and hold it forward (-). The transmis -
sion will shift to the range from which the vehicle can best be
slowed down.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip
and the vehicle could skid, causing a collision or
personal injury.

STARTING AND OPERATING 171
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will provide mechanical steering
capability if power assist is lost.

If for some reason the power assist is interrupted, it will still be
possible to steer your vehicle. Under these conditions, you will
observe a substantial increase in steering effort, especially at
very low vehicle speeds and during parking maneuvers.

NOTE:
• Increased noise levels at the end of the steering wheeltravel are considered normal and do not indicate that there
is a problem with the power steering system.
• Upon initial start-up in cold weather, the power steering pump may make noise for a short amount of time. This is
due to the cold, thick fluid in the steering system. This
noise should be considered normal, and it does not in any
way damage the steering system.
Power Steering Fluid Check
Checking the power steering fluid level at a defined service
interval is not required. The fluid should only be checked if
a leak is suspected, abnormal noises are apparent, and/or
the system is not functioning as anticipated. Coordinate
inspection efforts through your authorized dealer. CAUTION!
Prolonged operation of the steering system at the end of
the steering wheel travel will increase the steering fluid
temperature and it should be avoided when possible.
Damage to the power steering pump may occur.
WARNING!
Fluid level should be checked on a level surface and with
the engine off to prevent injury from moving parts and
to ensure accurate fluid level reading. Do not overfill.
Use only manufacturer's recommended power steering
fluid.
