3. Remove and replace the battery. When re-
placing the battery, match the + sign on the
battery to the + sign on the inside of the battery
clip, located on the back cover. Avoid touching
the new battery with your fingers. Skin oils may
cause battery deterioration. If you touch a
battery, clean it with rubbing alcohol.
4. To assemble the RKE transmitter case, snap
the two halves together.
General InformationThe RKE transmitter and receivers operate on a
carrier frequency of 433.92 MHz as required by
EEC regulations. These devices must be certi-
fied to conform to specific regulations in each
individual country. Two sets of regulations are
involved: ETS (European Telecommunication
Standard) 300–220, which most countries use,
and German BZT federal regulation 225Z125,
which is based on ETC 300–220 but has addi-
tional unique requirements. Other defined re-
quirements are noted in ANNEX VI of COMMIS-
SION DIRECTIVE 95/56/EC. Operation is
subject to the following two conditions:
•This device may not cause harmful interfer-
ence. •
This device must accept any interference
received, including interference that may
cause undesired operation.
If your RKE transmitter fails to operate from a
normal distance, check for these two condi-
tions:
1. Weak battery in RKE transmitter. The ex-
pected life of the battery is a minimum of three
years.
2. Closeness to a radio transmitter such as a
radio station tower, airport transmitter, and
some mobile or CB radios.
DOOR LOCKSThe power door locks can be manually locked
from inside the vehicle by using the door lock
knob. To lock each door, push the door lock
knob on each door trim panel downward. To
unlock the front doors, pull the inside door
handle to the first detent. To unlock the rear
doors, pull the door lock knob on the door trim
panel upward. If the lock knob is down when
the door is closed, the door will lock. Therefore,
make sure the key is not inside the vehicle

Entry RKE Transmitter In Vehicle
To minimize the possibility of unintentionally
locking a Passive Entry RKE transmitter inside
your vehicle, the Passive Entry system is
equipped with an automatic door unlock fea-
ture which will function if there is no Key Fob
present in the ignition.
If one of the vehicle doors is open and the door
panel switch is used to lock the vehicle, once
all open doors have been closed the vehicle
checks the inside and outside of the vehicle for
any valid Passive Entry RKE transmitters. If one
of the vehicle’s Passive Entry RKE transmitters
is detected inside the vehicle, and no other
valid Passive Entry RKE transmitters are de-
tected outside the vehicle, the Passive Entry
System automatically unlocks all vehicle doors
and chirps the horn three times (on the third
attempt ALL doors will lock and the Passive
Entry RKE transmitter can be locked in the
vehicle).

Inflatable Curtain (SABIC), Supplemental Seat-
Mounted Side Air Bags (SAB), and front seat
belt pretensioners, as required, depending on
the severity and type of impact.
Advanced Front Air Bags and Supplemental
Driver Side Knee Air Bag are designed to
provide additional protection by supplementing
the seat belts in certain frontal collisions de-
pending on the severity and type of collision.
Advanced Front Air Bags are not expected to
reduce the risk of injury in rear, or side colli-
sions.
The Advanced Front Air Bags and Supplemen-
tal Driver Side Knee Air Bag will not deploy in all
frontal collisions, including some that may pro-
duce substantial vehicle damage — for ex-
ample, some pole collisions, truck underrides,
and angle offset collisions. On the other hand,
depending on the type and location of impact,
Advanced Front Air Bags may deploy in
crashes with little vehicle front-end damage but
that produce a severe initial deceleration.
The side air bags will not deploy in all side
collisions. Side air bag deployment will depend
on the severity and type of collision.Because air bag sensors measure vehicle de-
celeration over time, vehicle speed and dam-
age by themselves are not good indicators of
whether or not an air bag should have de-
ployed.
Seat belts are necessary for your protection in
all accidents, and also are needed to help keep
you in position, away from an inflating air bag.
The ORC monitors the readiness of the elec-
tronic parts of the air bag system whenever the
ignition switch is in the START or ON/RUN
position. If the key is in the LOCK position, in
the ACC position, or not in the ignition, 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 bags even if the
battery loses power or it becomes discon-
nected prior to deployment.
Also, 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 is first turned to
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 if the light comes on
again after initial startup.
It also includes diagnostics that will illuminate
the instrument cluster Air Bag Warning Light if a
malfunction is noted that could affect the air
bag system. The diagnostics also record the
nature of the malfunction.
WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t have
the air bags to protect you in a collision. If the
light does not come on as a bulb check when
the ignition is first turned on, stays on after
you start the vehicle, or if it comes on as you
drive, have an authorized dealer service the
air bag system immediately.

especially applies to children. The side curtain
air bag is only about 3-1/2 in (9 cm) thick when
it is inflated.
Because air bag sensors estimate deceleration
over time, vehicle speed and damage are not
good indicators of whether or not an air bag
should have deployed.
NOTE:
In a rollover the pretensioners, and/or SAB
and SABIC air bags may deploy on both
sides of the vehicle.
Front And Side Impact Sensors
In front and side impacts, impact sensors can
aid the ORC in determining appropriate re-
sponse to impact events.
Enhanced Accident Response System
In the event of an impact causing air bag
deployment, if the communication network re-
mains intact, and the power remains intact,
depending on the nature of the event the ORC
will determine whether to have the Enhanced
Accident Response System perform the follow-
ing functions:
•Cut off fuel to the engine. •
Flash hazard lights as long as the battery
has power or until the ignition key is turned
off.
• Turn on the interior lights, which remain on as
long as the battery has power or until the
ignition key is removed.
• Unlock the doors automatically.
If A Deployment Occurs
The Advanced Front Air Bags are designed to
deflate immediately after deployment.
NOTE:
Front and/or side air bags will not deploy in
all collisions. This does not mean some-
thing is wrong with the air bag system.
If you do have a collision which deploys the air
bags, any or all of the following may occur:
• The nylon air bag material may sometimes
cause abrasions and/or skin reddening to
the driver and front passenger as the air
bags deploy and unfold. The abrasions are
similar to friction rope burns or those you
might get sliding along a carpet or gymna-
sium floor. They are not caused by contact
with chemicals. They are not permanent and normally heal quickly. However, if you
haven’t healed significantly within a few
days, or if you have any blistering, see your
doctor immediately.
• As the air bags deflate, you may see some
smoke-like particles. The particles are a nor-
mal by-product of the process that gener-
ates the non-toxic gas used for air bag
inflation. These airborne particles may irri-
tate 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 cloth-
ing, follow the garment manufacturer’s in-
structions for cleaning.
Do not drive your vehicle after the air bags have
deployed. If you are involved in another colli-
sion, the air bags will not be in place to protect
you.

WARNING!
Deployed air bags and seat belt pretensioners
cannot protect you in another collision. Have
the air bags, seat belt pretensioners, and the
front seat belt retractor assemblies replaced
by an authorized dealer immediately. Also,
have the Occupant Restraint Controller
(ORC) system serviced as well.
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.
(Continued)
WARNING! (Continued)
• 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 ser-
viced in any way (including removal or
loosening/tightening of seat attachment
bolts), take the vehicle to your 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 your authorized
dealer. Air Bag Warning Light
You will want to have the air bags
ready to inflate for your protection
in a collision. The Air Bag Warning
Light monitors the internal circuits
and interconnecting wiring associ-
ated with air bag system electrical
components. While the air bag system is de-
signed to be maintenance free. If any of the
following occurs, have an authorized dealer
service the air bag system immediately.
• The Air Bag Warning Light does not come on
during the four to eight seconds when the
ignition switch is first turned to the ON/RUN
position.
• The Air Bag Warning Light remains on after
the four to eight-second interval.
• The Air Bag Warning Light comes on inter-
mittently or remains on while driving.
