The roof-rail airbags for the driver, right front passenger,
and second row outboard passengers are in the
ceiling above the side windows.
{CAUTION:
If something is between an occupant and an
airbag, the airbag might not inate properly
or it might force the object into that person
causing severe injury or even death. The path
of an inating airbag must be kept clear.
Do not put anything between an occupant and
an airbag, and do not attach or put anything
on the steering wheel hub or on or near any
other airbag covering.
If your vehicle has roof-rail airbags, never
secure anything to the roof of your vehicle by
routing the rope or tie down through any door
or window opening. If you do, the path of an
inating roof-rail airbag will be blocked. Driver Side shown, Passenger Side similar

Rollover capable roof-rail airbags are designed to help
contain the head and chest of occupants in the outboard
seating positions in the rst and second rows. The
rollover capable roof-rail airbags are designed to help
reduce the risk of full or partial ejection in rollover events,
although no system can prevent all such ejections.
But airbags would not help in many types of collisions,
primarily because the occupant’s motion is not
toward those airbags. SeeWhen Should an Airbag
Inflate? on page 1-59for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.
What Will You See After an
Airbag Inates?
After the frontal airbags inate, they quickly deate,
so quickly that some people may not even realize
an airbag inated. Roof-rail airbags may still be at
least partially inated for some time after they deploy.
Some components of the airbag module may be hot for
several minutes. For location of the airbag modules,
seeWhat Makes an Airbag Inflate? on page 1-60.
The parts of the airbag that come into contact
with you may be warm, but not too hot to touch.
There may be some smoke and dust coming
from the vents in the deated airbags.Airbag ination does not prevent the driver from
seeing out of the windshield or being able to steer
the vehicle, nor does it prevent people from leaving
the vehicle.
{CAUTION:
When an airbag inates, there may be dust
in the air. This dust could cause breathing
problems for people with a history of asthma or
other breathing trouble. To avoid this, everyone
in the vehicle should get out as soon as it is
safe to do so. If you have breathing problems
but cannot get out of the vehicle after an airbag
inates, then get fresh air by opening a window
or a door. If you experience breathing problems
following an airbag deployment, you should
seek medical attention.
Your vehicle has a feature that may automatically
unlock the doors, turn the interior lamps on, and turn
the hazard warning ashers on when the airbags inate.
You can lock the doors, turn the interior lamps off,
and turn the hazard warning ashers off by using the
controls for those features.
1-61

Safety belts help keep the passenger in position on
the seat during vehicle maneuvers and braking, which
helps the passenger sensing system maintain the
passenger airbag status. See “Safety Belts” and
“Child Restraints” in the Index for additional information
about the importance of proper restraint use.If you ever pull the shoulder portion of the belt out all
the way, you will engage the child restraint locking
feature. This may unintentionally cause the passenger
sensing system to turn the airbag(s) off for some
adult size occupants. If this happens, just let the belt
go back all the way and start again.
{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on,
it means that something may be wrong with
the airbag system. If this ever happens, have
the vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger’s seat may not have the protection
of the airbag(s). SeeAirbag Readiness Light
on page 3-29for more on this, including
important safety information.

Keys
{CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons, children
or others could be badly injured or even killed.
They could operate the power windows or
other controls or even make the vehicle move.
The windows will function with the keys in the
ignition and they could be seriously injured
or killed if caught in the path of a closing
window. Do not leave the keys in a vehicle
with children.
Use the double-sided key for the ignition and driver’s
door lock.
When a new vehicle is delivered, the dealer/retailer
provides the owner with a pair of identical keys and a
key code number.
2-3

The key code number tells your dealer/retailer or a
qualied locksmith how to make extra keys. Keep this
number in a safe place. If you keys are lost, new keys can
be made using this number. Your dealer/retailer should
also have this number.
Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.
If you are locked out of your vehicle, call the Roadside
Assistance Center. SeeRoadside Assistance Program
on page 7-6.

Remote Keyless Entry (RKE)
System Operation
You can lock and unlock the vehicle’s doors and disarm
or arm the theft-deterrent system from about 3 feet (1 m)
up to 30 feet (9 m) away using the Remote Keyless
Entry (RKE) transmitter. SeeContent Theft-Deterrent
on page 2-14for additional information.
UNLOCK:Press this
button to unlock the driver’s
door and turn on the
interior lamps. The parking
lamps may also ash,
and the horn may chirp,
when this button is pressed.
Press the unlock button again within three seconds and
all of the doors will unlock.LOCK:Press this button to lock all the doors. The
parking lamps may also ash and the horn may chirp
when this button is pressed.
If a door is open or ajar when the lock button is pressed,
the doors will lock, but the theft-deterrent system will
not arm until the open door is closed.
Different feedback modes can be programmed through
the Driver Information Center (DIC). See “Remote
Keyless Entry Feedback” underDIC Operation and
Displays on page 3-40.
L(Panic):Press this button to make the horn sound
and the headlamps and taillamps ash for up to
30 seconds. To turn them off, do one of these three
things: wait for 30 seconds; press the panic button
again; or start the vehicle.
2-5

Matching Transmitter(s) to
Your Vehicle
Each RKE transmitter is coded to prevent another
transmitter from unlocking your vehicle. If a transmitter is
lost or stolen, a replacement can be purchased through
your dealer/retailer. Remember to bring any remaining
transmitters with you when you go to your dealer/retailer.
When the dealer/retailer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer/retailer has
coded the new transmitter, the lost transmitter will not
unlock your vehicle. Each vehicle can have a maximum
of four transmitters matched to it.
Battery Replacement
Under normal use, the battery in the RKE transmitter
should last about two years.
The battery is weak if the transmitter will not work at the
normal range in any location. If you have to get close
to your vehicle before the transmitter works, it is
probably time to change the battery.
Notice:When replacing the battery, use care not
to touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.To replace the battery:
1. Insert a coin, or similar object, in the slot between
the covers of the transmitter housing. Gently pry
the transmitter apart.
2. Remove and replace the battery with a
three-volt CR2032 or equivalent battery.
3. Align the covers and snap them together.
4. Check the operation of the transmitter.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers, especially children, can easily
open the doors and fall out of a moving
vehicle. When a door is locked, the handle
will not open it. You increase the chance
of being thrown out of the vehicle in a
crash if the doors are not locked. So, wear
safety belts properly and lock the doors
whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.There are several ways to lock and unlock your vehicle.
From the outside, use the key in the driver’s door or
use the remote keyless entry transmitter.
From the inside, use the manual lock levers or power
door lock switch.
2-7

Power Door Locks
The power door lock
switches are located on
the driver’s and the
front passenger’s doors.
Press L (lock) to lock all the doors at once.
To unlock all the doors, press U (unlock).
Programmable Automatic
Door Locks
If your vehicle has an automatic transmission, it is
programmed from the factory to lock the doors
automatically when the shift lever is moved out of
PARK (P). All the doors will unlock when the shift lever
is moved back into PARK (P).
If your vehicle has a manual transmission, it is
programmed from the factory to lock the doors
automatically when the vehicle speed is greater than
15 mph (24 km/h). The doors will unlock when the key is
removed from the ignition.
To personalize the automatic door locks, see “Automatic
Door Locks” underDIC Operation and Displays on
