This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this
device must accept any interference received, including
interference that may cause undesired operation of
the device.
Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
This system has a range of about 3 feet (1 m) up to 30 feet
(9 m). At times you may notice a decrease in range. This
is normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer to
your vehicle for the transmitter to work, try this:

Check to determine if battery replacement or
transmitter resynchronization is necessary. See the
instructions that follow.

Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.

Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.
If you're still having trouble, see your dealer or a
qualified technician for service.
Operation
The driver's door will unlock automatically when
UNLOCK is pressed. If UNLOCK is pressed again
within five seconds, the passenger's doors will also
unlock. All doors will lock when LOCK is pressed.
The tailgate or panel doors will unlock when the
REAR 2X button is pressed twice within five seconds,
as long as the ignition is turned to OFF. If the ignition is
on, the REAR 2X button will only work if the
transmission is in PARK (P).
The system will turn on the interior lamps for about
40 seconds (or until the ignition is turned to RUN),
when you unlock the doors, tailgate or panel doors. The
interior lamps will go off when you lock the doors.
Operating the keyless entry transmitter may interact
with the theft
-deterrent system. See ªTheft-Deterrent
Systemº in the Index.

3. Turn the ignition from OFF to RUN three times
quickly (within five seconds). The vehicle will
respond by locking the doors, unlocking the driver's
doors and releasing the tailgate or panel doors. Your
transmitter is now ready to match the vehicle.
4. Press and hold the LOCK and UNLOCK buttons on
the first transmitter for 15 seconds. The vehicle will
respond as in Step 3.
5. Repeat Step 4 for the remaining transmitters.
6. When you have finished matching all of your
transmitters, replace the RADIO fuse (Fuse 17).
7. Check that all transmitters work by pressing
their buttons.
If the transmitters don't work, or if you'd rather not
match the transmitters yourself, see your dealer.Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's 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.
Use one three volt, type CR2032, or equivalent battery.

means that both your keyless entry transmitter and the
power door lock switch will actively arm the system. To
change the factory setting, do the following:
1. Press the UNLOCK switch on the door.2. Count the number of chimes you hear. The number
of chimes tells you which mode your vehicle is
set for.
3. Press the UNLOCK switch on the door until you
hear the number of chimes that correspond to the
mode selection you want.
Mode 1: Alarm System Off (The system will not arm.)
Mode 2: Keyless Entry Transmitter Lock (When you
lock your doors using the keyless entry transmitter, the
system will arm.)
Mode 3: Keyless Entry Transmitter/Power Door Lock
Switch (If you use either the keyless entry transmitter or
the power door lock switch to lock the doors, the system
will arm.)
Mode 4: Passive arming and Keyless Entry
Transmitter/Power Door Lock Switch Arming (The
system will arm itself after all doors are closed, plus
arming per mode 3.)

2-23 How to Start the Engine
1. Without pushing the accelerator pedal, turn your
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as your
engine gets warm.
NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to be
drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid
draining your battery or damaging your starter.
2. If it doesn't start right away, hold your key in
START. If it doesn't start in 10 seconds, push the
accelerator pedal all the way down for five more
seconds, unless it starts sooner.
3. If your engine still won't start (or starts but then
stops), wait 15 seconds and start over.
When the engine starts, let go of the key and the
accelerator pedal.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you don't,
your engine might not perform properly.
If you ever have to have your vehicle towed, see
the part of this manual that tells how to do it
without damaging your vehicle. See ªTowing
Your Vehicleº in the Index.

2-41 Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high or high
to low, pull the turn signal lever all the way toward you.
Then release it.
When the high beams are
on, this light on the
instrument panel also
will be on.
Windshield Wipers
You operate the windshield
wipers by turning the
control with the wiper
symbol on it.
For a single wiping cycle, turn the control to MIST.
Hold it there until the wipers start, then let go. Thewipers will stop after one cycle. If you want more
cycles, hold the control on MIST longer.
You can set the wiper speed for a long or short delay
between wipes. This can be very useful in light rain or
snow. Turn the control to choose the delay time. The
closer to LOW, the shorter the delay.
For steady wiping at low speed, turn the control to the
LOW position. For high
-speed wiping, turn the control
further, to HIGH. To stop the wipers, turn the control
to OFF.
Damaged wiper blades may prevent you from seeing
well enough to drive safely. To avoid damage, be sure to
clear ice and snow from the wiper blades before using
them. If they are frozen to the windshield, carefully
loosen or thaw them. If your blades do become
damaged, get new blades or blade inserts.
Heavy snow or ice can overload your wipers. The
windshield wiper motor is protected from overload by a
circuit breaker and a fuse. If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. Although the circuit is protected from electrical
overload, overload due to heavy snow, etc. may cause
wiper linkage damage. Always clear ice and heavy
snow from the windshield before using your
windshield wipers.

2-47 Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as the
taillamps, sidemarker, parking lamps and the instrument
panel lights.
To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is
off. Then start the vehicle. The automatic headlamp
system will stay off until you release the parking brake.
The headlamp switch can always be used to turn on the
regular lamps. As with any vehicle, you should turn on
the regular headlamp system when you need it.
Headlamps-On Reminder
A chime will sound when your headlamps are turned on
and your ignition is in OFF, LOCK or ACCESSORY.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.The DRL system will make your headlamps come on at
a reduced brightness when:

the ignition is on,

the headlamp switch is off,

the parking brake is released and

it is bright enough outside and the automatic
headlamps are off.
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won't be on.
Your instrument panel won't be lit up either.
When it begins to get dark, your DRL will turn off. Your
headlamps will come on automatically.
When it begins to get bright, the regular lamps will go
off, and your headlamps will change to the reduced
brightness of DRL.
To idle your vehicle with the DRL off, set the parking
brake. The DRL will stay off until you release the
parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

The length of time that the headlamps stay on after the
ignition is turned off can be adjusted by pressing and
holding the HEADLAMP DELAY button. The
delay can be varied in five steps (0, 15, 30, 60 and
90 seconds). When the HEADLAMP DELAY button is
held in, the Light Emitting Diode (LED) on the mirror
will show five step changes in brightness. When the
LED is at its brightest the headlamp delay will be
90 seconds, and when it is most dim the delay will be
zero seconds.
Interior Lamps
Instrument Panel Intensity Control
The instrument panel intensity control is located next to
the parking/headlamp switch. Turn the thumbwheel up
to adjust the instrument panel lights. Turn the
thumbwheel up to the first notch to return the radio
display and gear shift indicator LED display to full
intensity when the headlamps or parking lamps are on.
To turn on the dome lamps (with the vehicle doors
closed) turn the thumbwheel up to the second
notch position.
Exit Lighting and Delayed Illumination
With this feature, your interior lamps will come on and
stay on for up to 25 seconds when entering the vehicle
and up to 5 seconds when leaving your vehicle.
When the doors are opened, the dome lamps will only
come on if the dome lamp button is in the out position.
When all doors are closed or the dome lamp button is
pressed in, the lamps will stay on for a short period of
time and will then fade out.
Dome Lamps
The dome lamps will come on when you open the doors.
You can also turn the dome lamps on by turning the
thumbwheel, located next to the parking/headlamps
switch knob, all the way up to the second notch. In this
position, the dome lamps will remain on whether the
doors are opened or closed.
