ten second pre-alarm will occur. The horn will chirp and
the lights will ash. If the key is not placed in the
ignition and turned to START or the door is not unlocked
by pressing the unlock button on the RKE transmitter
during the ten second pre-alarm, the alarm will go
off. Your vehicle’s headlamps will ash and the horn will
sound for about two minutes, then will turn off to save
the battery power.
The theft-deterrent system will not activate if the doors
are locked with the vehicle’s key or the manual door
lock. It activates only if you use the power door
lock switch with the door open or the RKE transmitter.
You should also remember that you can start your
vehicle with the correct ignition key if the alarm has been
set off.
Here is how to avoid setting off the alarm by accident:
If you do not want to activate the theft-deterrent
system, the vehicle should be locked with the
door key after the doors are closed.
Always unlock a door with the RKE transmitter.
Unlocking a door any other way will set off the alarm
if the system has been armed.If you set off the alarm by accident, turn off the alarm by
pressing unlock on the RKE transmitter or by placing
the key in the ignition and turning it to START.
Testing the Alarm
To test the alarm:
1. From inside the vehicle, lower the driver’s window
and open the driver’s door.
2. Activate the system by locking the doors with the
RKE transmitter.
3. Get out of the vehicle, close the door and wait for
the security light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
If the alarm does not sound when it should, but the
vehicle’s headlamps ash, check to see if the horn
works. The horn fuse may be blown. To replace the
fuse, seeFuses and Circuit Breakers on page 5-100.
If the alarm does not sound or the vehicle’s headlamps
do not ash, see your dealer/retailer for service.

Ignition Positions
With the key in the ignition,
you can turn it to four
different positions.
In order to shift out of PARK (P), ignition must be in
ON/RUN or ACC/ACCESSORY and the regular brake
pedal must be applied.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the key.
Use the correct key and turn the key only with your
hand. Make sure the key is all the way in. If none of
this works, then your vehicle needs service.
A (LOCK/OFF):This is the only position in which you
can remove the key. This position locks the ignition and
transmission. If the steering wheel is locked, move it from
right to left and turn the key to ACC/ACCESSORY. If
none of this works, then your vehicle needs service.B (ACC/ACCESSORY):This position allows you to use
things like the radio and the windshield wipers while
the engine is off. This position will also allow you to turn
off the engine.
C (ON/RUN):This is the position that the switch returns
to after you start your engine and release the key.
The switch stays in ON/RUN when the engine is
running. But even when the engine is not running, you
can use ON/RUN to operate your electrical power
accessories, and to display some instrument panel
warning lights.
The battery could be drained if you leave the key in the
ACC/ACCESSORY or ON/RUN position with the
engine off. You may not be able to start your vehicle if
the battery is allowed to drain for an extended period
of time.
D (START):This position starts the engine. When the
engine starts, release the key. The ignition switch
will return to ON/RUN for normal driving.
2-26

Key In the Ignition
Never leave your vehicle with the keys inside, as it is an
easy target for joy riders or thieves. If you leave the key in
the ignition and park your vehicle, a chime will sound
when you open the driver’s door. Always remember to
remove your key from the ignition and take it with you.
This will lock your ignition and transmission. Also, always
remember to lock the doors.
The battery could be drained if you leave the key in the
ignition while your vehicle is parked. You may not be able
to start your vehicle after it has been parked for an
extended period of time.
Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the ignition key is turned off:
Audio System
Power Windows
Sunroof (if equipped)Power to the windows and sunroof will work up to
10 minutes or until a door is opened.
The radio continues to work for 10 minutes or until the
driver’s door is opened.
For an additional 10 minutes of operation, close all the
doors and turn the key to ON/RUN and then back to
LOCK/OFF.
All these features will work when the key is in the
ON/RUN or ACC/ACCESSORY positions.
Starting the Engine
Move your shift lever to PARK (P) or NEUTRAL (N). Your
engine will not start in any other position – this is a safety
feature. To restart when you are already moving, use
NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your vehicle
is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
2-27

Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts, let go
of the key. The idle speed will go down as your
engine gets warm. Do not race the engine
immediately after starting it. Operate the engine and
transmission gently to allow the oil to warm up and
lubricate all moving parts.
Your vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. If the ignition key is turned
to the START position, and then released when the
engine begins cranking, the engine will continue
cranking for a few seconds or until the vehicle starts.
If the engine does not start and the key is held in
START for many seconds, cranking will be stopped
after 15 seconds to prevent cranking motor damage.
To prevent gear damage, this system also prevents
cranking if the engine is already running. Engine
cranking can be stopped by turning the ignition
switch to the ACC/ACCESSORY or LOCK/OFF
position.
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try, to
let the cranking motor cool down.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F or−18°C),
it could be ooded with too much gasoline. Try
pushing the accelerator pedal all the way to the oor
and holding it there as you hold the key in START for
up to a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the cranking
motor to cool down. When the engine starts, let go of
the key and accelerator. If the vehicle starts briey
but then stops again, do the same thing. This clears
the extra gasoline from the engine. Do not race the
engine immediately after starting it. Operate the
engine and transmission gently until the oil warms up
and lubricates all moving parts.
Notice:The 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/retailer. If you do not, your engine
might not perform properly. Any resulting damage
would not be covered by your vehicle’s warranty.

Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system. You must fully
apply your regular brake rst and then press the
shift lever button before you can shift from PARK (P)
when the ignition key is in ON. If you cannot shift out of
PARK (P), ease pressure on the shift lever, then
push the shift lever all the way into PARK (P) as you
maintain brake application. Then press the shift
lever button and move the shift lever into another gear.
SeeShifting Out of PARK (P) on page 2-37.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transmission,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 4-20.NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
{CAUTION:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.
Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine running at high speed may damage
the transmission. The repairs would not be
covered by your warranty. Be sure the engine is not
running at high speed when shifting your vehicle.
