SAFETY287
As the air bags deflate, you may see some
smoke-like particles. The particles are a normal
by-product of the process that generates the
non-toxic gas used for air bag 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 instructions for cleaning.
Do not drive your vehicle after the air bags have
deployed. If you are involved in another collision,
the air bags will not be in place to protect you.
NOTE:
Air bag covers may not be obvious in the interior
trim, but they will open during air bag deploy -
ment.
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 communication
network remains intact, and the power remains
intact, depending on the nature of the event, the
Occupant Restraint Controller (ORC) will determine
whether to have the Enhanced Accident Response
System perform the following functions:
Cut off fuel to the engine (if equipped)
Cut off battery power to the electric motor (if
equipped)
Flash hazard lights as long as the battery has
power
Turn on the interior lights, which remain on as
long as the battery has power or for 15 minutes
from the intervention of the Enhanced Accident
Response System
Unlock the power door locks
Your vehicle may also be designed to perform any
of these other functions in response to the
Enhanced Accident Response System:
Turn off the Fuel Filter Heater, Turn off the HVAC
Blower Motor, Close the HVAC Circulation Door
Cut off battery power to the:
Engine
Electric Motor (if equipped)
Electric power steering
Brake booster
Electric park brake
Automatic transmission gear selector
Horn
Front wiper
NOTE:After an accident, remember to cycle the ignition to
the STOP (OFF/LOCK) position and remove the key
from the ignition switch to avoid draining the
battery. 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. If
there are no fuel leaks or damage to the vehicle
electrical devices (e.g. headlights) after an
accident, reset the system by following the
procedure described here. If you have any doubt,
contact an authorized dealer.
Enhanced Accident Response System
Reset Procedure
If Applicable, refer to the “Hybrid Supplement” for
additional information.
In order to reset the Enhanced Accident Response
System functions after an event, the ignition switch
must be changed from ignition START or ON/RUN
to ignition 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.
WARNING!

Deployed air bags and seat belt pretensioners
cannot protect you in another collision. Have the air
bags, seat belt pretensioners, and the seat belt
retractor assemblies replaced by an authorized
dealer immediately. Also, have the Occupant
Restraint Controller System serviced as well.

(Continued)
PREPARATIONS FOR JUMP START
The battery in your vehicle is located under the
driver's front seat. There are remote terminals
located under the hood to assist in jump starting.
Jump Starting Posts

NOTE:The remote battery posts are viewed by standing
on the right side of the vehicle looking over the
fender. The positive battery post may be covered
with a protective cap. Lift up on the cap to gain
access to the positive battery post. Do not jump off
fuses. Only jump directly off positive post which
has a positive (+) symbol on or around the post.
See the following steps to prepare for jump
starting:
1. Apply the parking brake, shift the automatic
transmission into PARK (P) and turn the
ignition OFF.

2. Turn off the heater, radio, and all electrical accessories.
3. If using another vehicle to jump start the battery, park the vehicle within the jumper
cables’ reach, apply the parking brake and
make sure the ignition is OFF.
NOTE:Be sure that the disconnected cable ends do not
touch each other, or either vehicle, until properly
connected for jump starting.JUMP STARTING PROCEDURE
NOTE:Make sure at all times that unused ends of jumper
cables are not contacting each other or either
vehicle while making connections.
Remote Positive (+) Post
Remote Negative (-) Post
WARNING!
Do not allow vehicles to touch each other as this
could establish a ground connection and
personal injury could result.
WARNING!
Take care to avoid the radiator cooling fan
whenever the hood is raised. It can start
anytime the ignition switch is ON. You can be
injured by moving fan blades.
Remove any metal jewelry such as rings,
watch bands and bracelets that could make
an inadvertent electrical contact. You could be
seriously injured.
Batteries contain sulfuric acid that can burn
your skin or eyes and generate hydrogen gas
which is flammable and explosive. Keep open
flames or sparks away from the battery.
WARNING!
Failure to follow this jump starting procedure
could result in personal injury or property
damage due to battery explosion.
CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster
vehicle or the discharged vehicle.
WARNING!

IN CASE OF EMERGENCY323
In the event it is observed that the temperature
gauge is moving towards or close to the HOT (H)
position, you can reduce the potential for
overheating by taking the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans -
mission in NEUTRAL (N), but do not increase the
engine idle speed while preventing vehicle
motion with the brakes.
If your Air Conditioner (A/C) is on, turn it off. The
A/C system adds heat to the engine cooling
system and turning the A/C off can help remove
this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the heater
core to act as a supplement to the radiator and
aids in removing heat from the engine cooling
system.
MANUAL PARK RELEASE
To move the vehicle in cases where the
transmission will not shift out of PARK (P) (such as
a depleted battery), a Manual Park Release is
available.
To activate the Manual Park Release, see the
following steps:

1. Apply firm pressure to the brake pedal while seated in the driver’s seat.

2. Apply the Electric Park Brake (EPB), if possible.
3. Using a flathead screwdriver or similar tool, remove the Manual Park Release access
cover, which is to the lower left of the steering
column.

Manual Park Release Access Cover
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads
“H,” pull over and stop the vehicle. Idle the
vehicle with the air conditioner turned off until
the pointer drops back into the normal range. If
the pointer remains on the “H” and you hear
continuous chimes, turn the engine off
immediately and call for service.
WARNING!
You should be seated in the driver’s seat with
your foot firmly placed on the brake pedal to
maintain control of the vehicle before activating
the Manual Park Release. If possible, you should
apply the parking brake. Activating the Manual
Park Release will allow your vehicle to roll away if
it is not secured or properly connected to a tow
vehicle. Activating the Manual Park Release on
an unsecured vehicle could lead to serious
injury or death for those in or around the vehicle.
