Remote Panic Alarm
When the button with the horn symbol on the key
transmitter is pressed, the horn will sound and
the
headlamps and taillamps will flash for up to 30 seconds.
This can be turned off by pressing the horn button again,
waiting for
30 seconds, or starting the vehicle.
Matching Transmitter(s) To Your Vehicle
Each remote keyless entry 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. Remember
to bring any
remaining transmitters with you
when you go to your
dealer. When the dealer matches the replacement
transmitter
to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded
the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have only four transmitters
matched to it.

Key in the Ignition
If you leave your vehicle with the keys inside, it’s an
easy target for joy riders or professional thieves
-- so
don’t do it.
When you park your vehicle and open the driver’s door,
you’ll hear a chime reminding
you to remove your key
from the ignition and take
it with you. Always do this.
Your steering wheel will be locked, and
so will your
ignition and transmission. And remember to lock
the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out
of sight.
Put them
in a storage area, or take them with you.
Parking Lots
If you park in a lot where someone will be watching
your vehicle, it’s best to lock it up and take your keys.
But what
if you have to leave your ignition key? What if
you have to leave something valuable in your vehicle?
Put your valuables in a storage area, like your
glove box.
Lock all the doors except the driver’s.
Content Theft-Deterrent
Your vehicle is equipped
with
a Content
Theft-Deterrent
SECURITY alarm system.
With this system, the SECURITY light will flash as
you
open the door (if your ignition is off).
This light reminds you to activate the theft-deterrent
system. Here’s how
to do it:
1. Open the door.
2. Lock the door with the power door lock switch or the
remote keyless entry transmitter. The SECURITY
light should come
on and stay on.
3. Close all doors. The SECURITY light should go off
after approximately
30 seconds. The alarm is not
armed until the SECURITY light goes off.
If a door is opened without the key or the remote keyless
entry transmitter, the alarm will go
off. Your vehicle’s
high-beam headlamps will flash
and the horn will sound
for
30 seconds, then will turn off to save the battery power.

Ignition Positions
Use the key to turn the ignition switch to
five different positions.
C
ACCESSORY (A): This position lets you use things
like the radio and
the windshield wipers when the
engine is
off. Push in the key and turn it toward you.
Your steering wheel will remain locked, just as it was
before you inserted the key.
I NOTICE:
Don’t operate accessories in the ACCESSORY
position for long periods
of time. Prolonged
operation
of accessories in the ACCESSORY
position could drain your battery and prevent
you from starting your vehicle.
LOCK
(B): This position locks your ignition, steering
wheel and transmission.
It’s a theft-deterrent feature.
You will only be able to remove your key when the
ignition is turned to LOCK.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. Use
OFF if you must have
your vehicle in motion while the engine is off (for
example, if your vehicle is being towed).
RUN (D): This is the position for driving.
START (E): This position starts your engine.

NOTICE:
If your key seems stuck in LOCK and you can’t
turn
it, be sure you are using the correct key; if
so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. But turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch.
If none of this works, then your
vehicle needs service.
Retained Accessory Power
Your vehicle is equipped with a Retained Accessory
Power (RAP) feature which will allow certain features
on your vehicle to continue to work up to
20 minutes
after the ignition key
is turned to OFF.
Your radio, power windows, sunroof and overhead
console will work when the ignition key is in RUN or
ACCESSORY. Once the key is turned from RUN to
OFF, these features will continue to work for up to
20 minutes or until a door is opened.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position -- that’s a
safety feature.
To restart when you’re already moving,
use NEUTRAL (N) only.
I 1
I NOTICE:
Don’t 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.
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.

Automi ic Transmission Operation
There are several different positions for your shift lever.
PARK (P): This locks your rear wheels. It’s the best
position to use when you start your engine because your
vehicle can’t move easily.
It is dangerous to get out of your vehicle if the
shift lever is not fully in
PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don’t leave your vehicle when the engine is
running unless
you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured.
To be sure your
vehicle won’t move, even when you’re on fairly
level ground, always set your parking brake and
move the shift lever to
PARK (P).
See “Shifting Into PARK (P)” in the Index. If
you’re pulling
a trailer, see “Towing a Trailer” in
the Index.
Ensure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has
a
Brake-Transmission Shift Interlock (BTSI). You have to
fully apply your regular brakes before you can shift
from PARK (P) when the ignition key is
in RUN. If you
cannot shift out of PARK (P), ease pressure on the shift
lever
-- push the shift lever all the way into PARK (P)
(press
the button in on the console shift lever) as you
maintain brake application. Then move the shift lever
into the gear
you wish. See “Shifting Out of PARK (P)”
in the Index.
REVERSE (R): Use this gear to back up.
NOTICE:
Shifting to REVERSE (R) while your vehicle
is moving forward could damage your
transmission. 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, see
“Stuck: In Sand, Mud, Ice or Snow”
in the Index.

ProCarManuals.com

NEUTRAL (N): In this position, your engine doesn’t
connect with the wheels.
To restart when you’re already
moving, use
NEUTRAL (N) only.
Shifting out of PARK (P) or NEUTRAL (N) while
your engine
is “racing” (running at high speed) is
dangerous. Unless your foot is firmly on the
brake pedal, your vehicle could move very rapidly.
You could lose control and hit people or
objects. Don’t shift out
of PARK (P) or
NEUTRAL (N) while your engine is racing.
ml
I NOTICE:
Damage to your transmission caused by shifting
out
of PARK (P) or NEUTRAL (N) with the
engine racing isn’t covered by your warranty. DRIVE
(D):
This position is for normal driving. If you
need more power for passing, and you’re:
0 Going less than about 35 mph (55 krdh), push your
accelerator pedal about halfway down.
Going about 35 mph (55 krdh) or more, push the
accelerator all the way down.
You’ll shift down
to the next gear and have more power.
DRIVE
(D) should not be used when towing a trailer,
carrying a heavy load, driving on steep hills, or for
off-road driving. Select THIRD
(3) when operating the
vehicle under any of these conditions.
THIRD (3): This position is also used for normal
driving, however it offers more power and lower fuel
economy than DRIVE (D).
You should use THIRD (3)
when towing a trailer, carrying a heavy load, driving on
steep hills or winding roads or for off-road driving.
SECOND (2): This position gives you more power but
lower fuel economy than
THIRD (3). You can use
SECOND
(2) on hills. It can help control your speed as
you
go down steep mountain roads, but then you would
also want to use your brakes
off and on.
You can also use SECOND
(2) for starting your vehicle
from a stop
on slippery road surfaces.
2-19
ProCarManuals.com

FIRST (1): This position gives you even more power
but lower fuel economy than SECOND (2). You can use
it on very steep hills, or in deep snow or mud. If the
selector lever
is put in FIRST (1) while the vehicle is
moving forward, the transmission won’t shift into
FIRST (1) until the vehicle is going slowly enough.
NOTICE:
If your rear wheels can’t rotate, don’t try to
drive. This might happen if you were stuck in
very deep sand or mud or were up against a solid
object. You could damage your transmission.
Also, if you
stop when going uphill, don’t hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transmission.
Use your brakes or shift into
PARK
(P) to hold your vehicle in position
on a hill.
Parking Brake
To set the parking brake. hold the regular brake pedal
down with your
right foot. Push down the parking brake
pedal with your left foot.
If the ignition is on, the brake
system warning light
will come on.
To release the parking brake, hold the regular brake
pedal down.
Pull the BRAKE RELEASE lever. It is located on the
bottom of the driver’s side of the instrument panel.
