How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt
and allow it to retract completely to disen-
gage the Automatic Locking Mode and acti-
vate the vehicle sensitive (emergency) lock-
ing mode.
WARNING!
• The seat belt assembly must be replaced
if the switchable Automatic Locking Re-
tractor (ALR) feature or any other seat
belt function is not working properly
when checked according to the proce-
dures in the Service Manual.
• Failure to replace the seat belt assembly
could increase the risk of injury in colli-
sions.
• Do not use the Automatic Locking Mode
to restrain occupants who are wearing
the seat belt or children who are using
booster seats. The locked mode is only
used to install rear-facing or forward-
facing child restraints that have a har-
ness for restraining the child.
Supplemental Restraint Systems (SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask your autho-
rized dealer.
The air bag system must be ready to protect
you in a collision. The Occupant Restraint
Controller (ORC) monitors the internal cir-
cuits and interconnecting wiring associated
with the electrical Air Bag System Compo-
nents. Your vehicle may be equipped with the
following Air Bag System Components:
Air Bag System Components
•Occupant Restraint Controller (ORC)
•Air Bag Warning Light
•Steering Wheel and Column
•Instrument Panel
•Knee Impact Bolsters
•Driver and Front Passenger Air Bags
•Seat Belt Buckle Switch
•Supplemental Side Air Bags
•Front and Side Impact Sensors
•Seat Belt Pretensioners
Air Bag Warning Light
The ORC monitors the readiness of the
electronic parts of the air bag system when-
ever the ignition switch is in the START or
ON/RUN position. If the ignition switch is in
the OFF position or in the ACC position, the
air bag system is not on and the air bags will
not inflate.
The ORC contains a backup power supply
system that may deploy the air bag system
even if the battery loses power or it becomes
disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light
in the instrument panel for approximately
four to eight seconds for a self-check when
the ignition switch is first in the ON/RUN
position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects
a malfunction in any part of the system, it
turns on the Air Bag Warning Light, either
momentarily or continuously. A single chime
will sound to alert you if the light comes on
again after initial startup.
SAFETY
92

NOTE:
• Air bag covers may not be obvious in the
interior trim, but they will open during air
bag deployment.
• After any collision, the vehicle should be
taken to an authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communica-
tion network remains intact, and the power
remains intact, depending on the nature of
the event, the ORC will determine whether to
have the Enhanced Accident Response Sys-
tem perform the following functions:
• Cut off fuel to the engine.
• Flash hazard lights as long as the battery
has power or until the hazard light button is
pressed. The hazard lights can be deacti-
vated by pressing the hazard light button.
• Turn on the interior lights, which remain on
as long as the battery has power.
• Unlock the power door locks.
Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident Re-
sponse System functions after an event, the
ignition switch must be changed from igni-
tion START or ON/RUN to ignition OFF. Care-
fully 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 right side of the
instrument panel. Do not modify the
front bumper, vehicle body structure, or
add aftermarket side steps or running
boards.
WARNING!
• 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 prop-
erly if modifications are made. Take your
vehicle to an authorized dealer for any
air bag system service. If your seat, in-
cluding your trim cover and cushion,
needs to be serviced in any way (includ-
ing removal or loosening/tightening of
seat attachment bolts), take the vehicle
to your authorized dealer. Only manufac-
turer approved seat accessories may be
used. If it is necessary to modify the air
bag system for persons with disabilities,
contact your authorized dealer.
Event Data Recorder (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR
is to record, in certain crash or near crash-
like situations, such as an air bag deployment

If Engine Fails To Start
WARNING!
• Never pour fuel or other flammable liq-
uid into the throttle body air inlet open-
ing in an attempt to start the vehicle.
This could result in flash fire causing
serious personal injury.
• Do not attempt to push or tow your
vehicle to get it started. Vehicles
equipped with an automatic transmis-
sion cannot be started this way. Un-
burned fuel could enter the catalytic
converter and once the engine has
started, ignite and damage the converter
and vehicle.
• If the vehicle has a discharged battery,
booster cables may be used to obtain a
start from a booster battery or the battery
in another vehicle. This type of start can
be dangerous if done improperly. Refer
to “Jump Starting Procedure” in “In
Case Of Emergency” for further informa-
tion.Without Tip Start — Manual Transmission Only
If the engine fails to start after you have
followed the “Normal Starting” or “Extreme
Cold Weather” procedures, it may be flooded.
Push the accelerator pedal all the way to the
floor and hold it there while cranking the
engine. This should clear any excess fuel in
case the engine is flooded.
CAUTION!
To prevent damage to the starter, do not
crank the engine for more than 15 seconds
at a time. Wait 10 to 15 seconds before
trying again.
If the engine has been flooded, it may start to
run, but not have enough power to continue
running when the key is released. If this
occurs, continue cranking with the accelera-
tor pedal pushed all the way to the floor.
Release the accelerator pedal and the key
once the engine is running smoothly.If the engine shows no sign of starting after
two 15-second periods of cranking with the
accelerator pedal held to the floor, repeat the
“Normal Starting” or “Extreme Cold
Weather” procedures.
With Tip Start — Automatic Transmission Only
If the engine fails to start after you have
followed the “Normal Starting” or “Extreme
Cold Weather” procedures, it may be flooded.
To clear any excess fuel, push the accelerator
pedal all the way to the floor and hold it.
Then, turn the ignition switch to the START
position and release it as soon as the starter
engages. The starter motor will disengage
automatically in 10 seconds. Once this oc-
curs, release the accelerator pedal, turn the
ignition switch to the LOCK position, wait
10 to 15 seconds, then repeat the “Normal
Starting” procedure.
