NOTICE:
If your key seems stuck in OFF 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. 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.
A (OFF): This is the only position in which you can
insert or remove the key. This position locks the
ignition, steering wheel and transmission. It's a
theft
-deterrent feature.
B (ACCESSORY): This position allows you to use
things like the radio and the windshield wipers when the
engine is off. This position will allow you to turn off the
engine, but still turn the steering wheel.
C (ON): This position is for driving. If your vehicle has
an automatic transmission and you turn off the engine, the
transmission will lock. If you need to shift the transmission
out of PARK (P), the ignition key has to be in ON.
D (START): This position starts the engine.
Key Release Button (Manual Transmission)
The key cannot be
removed from the ignition
of manual transmission
vehicle unless the key
release button is used.
To remove the key, do the following:
1. Turn the key to ACCESSORY.
2. Press the button and turn the key to OFF.
Do not hold the button in while turning the
key to OFF.
3. Pull the key straight out of the ignition switch.

2-27
Retained Accessory Power (RAP)
The following accessories on your vehicle may be used
for up to 10 minutes after the ignition key is turned from
ON to OFF:

Radio

Power Windows

Audio Steering Wheel Controls (if programmed)

Sunroof (Option)
Power to these accessories stops after 10 minutes or
if a door is opened. If you want power for another
10 minutes, close all the doors and turn the ignition
key to ON and then back to OFF.
Starting Your Engine
Automatic Transmission
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.
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.

2-28
Manual Transmission
The gear selector should be in neutral and the parking
brake engaged. Hold the clutch pedal to the floor and
start the engine. Your vehicle won't start if the clutch
pedal is not all the way down
-- that's a safety feature.
1. With your foot off the accelerator pedal, turn your
ignition key to START. Then, just let go of the key;
the engine starts automatically. The idle speed will
go down as your engine gets warm.
2. If your engine won't start (or starts but then stops),
it could be flooded with too much gasoline. Try
pushing your accelerator pedal all the way to the
floor and holding it there as you turn the key to
START. If the vehicle starts briefly but then stops
again, do the same thing.
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.
Engine Coolant Heater (If Equipped)
In very cold weather, 0
F (-18
C) or colder, the engine
coolant heater can help. You'll get easier starting and
better fuel economy during engine warm
-up. Usually,
the coolant heater should be plugged in a minimum of
four hours prior to starting your vehicle. At temperatures
above 32
F (0
C), use of the coolant heater is
not required.

2-29
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is located on the driver's side of the engine
compartment near the engine oil dipstick. See
ªEngine Compartment Overviewº in the Index for
more information on location.
You must remove the plastic cap to access the plug.
3. Plug it into a normal, grounded 110
-volt AC outlet.
CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three
-prong
11 0
-volt AC outlet. If the cord won't reach, use a
heavy
-duty three-prong extension cord rated for
at least 15 amps.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it away
from moving engine parts. If you don't, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

Automatic Transmission Operation
The automatic transmission shift lever is located on the
center console between the front seats.
There are several different positions for the shift lever.PARK (P): This position locks the rear wheels. It's the
best position to use when you start the engine because
your vehicle can't move easily.
CAUTION:
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 ªShifting Into PARK (P)º in the Index.
If you're pulling a trailer, see ªTowing a Trailerº
in the Index.

2-31
Ensure 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 brakes 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.
Push the shift lever all the way into PARK (P) while
pressing the button on the shift lever as you maintain
brake application. Then move the shift lever into the
gear you wish. See ªShifting Out of PARK (P)º in
the Index.
NOTICE:
Shifting to REVERSE (R) while your vehicle is
moving forward could damage your
transmission. Shift to REVERSE (R) only after
your vehicle has stopped.
REVERSE (R): Use this gear to back up.
At low vehicle speeds, you can also use REVERSE (R)
to rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transmission. See
ªStuck in Sand, Mud, Ice or Snowº in the Index for
additional information.NEUTRAL (N): In this position, the engine doesn't
connect with the wheels. To restart when you're already
moving, use NEUTRAL (N) only. You can also use
NEUTRAL (N) when your vehicle is being towed.
CAUTION:
Shifting into a drive gear while your engine is
ªracingº (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
into a drive gear while your engine is racing.
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.

Manual Transmission Operation
The following explains how to operate your vehicle's
manual transmission.
This is the shift pattern
for your vehicle.
FIRST (1): Press the clutch and shift into FIRST (1).
Then, slowly let up on the clutch pedal as you press the
accelerator pedal.
You can shift into FIRST (1) when you're going less
than 20 mph (32 km/h). If you've come to a complete
stop and it's hard to shift into FIRST (1), put the shift
lever in NEUTRAL and let up on the clutch. Press the
clutch pedal back down. Then try shifting into
FIRST (1) again.SECOND (2): Press the clutch pedal to the floor
as you let up on the accelerator pedal and shift into
SECOND (2). Then, slowly let up on the clutch pedal
as you press the accelerator pedal.
THIRD (3), FOURTH (4), and FIFTH (5): Shift into
THIRD (3), FOURTH (4) and FIFTH (5) the same way
you do for SECOND (2). Slowly let up on the clutch
pedal as you press the accelerator pedal.
To stop, let up on the accelerator pedal and press the
brake pedal. Before the vehicle comes to a complete
stop, press the clutch pedal and brake pedal, and shift
into NEUTRAL.
NEUTRAL: Use this position when you idle the engine.
REVERSE (R): Use this gear to back up. Press the
clutch pedal and shift into REVERSE (R). Slowly let up
on the clutch pedal as you press the accelerator pedal.
Use REVERSE (R), along with the parking brake, when
you park your vehicle. See ªParking Your Vehicle
(Manual Transmission Only)º later in this section for
more information.
If your vehicle has a manual transmission, in order for
you to remove the key from the ignition, you must press
the key release button on the ignition switch. See ªKey
Release Buttonº in the Index for more information.

2-38
Shift Speeds
CAUTION:
If you skip a gear when you downshift, you could
lose control of your vehicle. You could injure
yourself or others. Don't shift down more than
one gear at a time when you downshift.
NOTICE:
If you skip more than one gear when you
downshift, or if you race the engine when you
release the clutch pedal while downshifting, you
could damage the clutch or the transmission.
If the vehicle speed drops below 20 mph (32 km/h), or
if the engine is not running smoothly, you should
downshift to the next lower gear. You may have to
downshift two or more gears to keep the engine running
smoothly or for good performance.
Parking Brake
The parking brake pedal
is located on the lower
portion of the instrument
panel to the left of the
steering wheel.
To set the parking brake, hold the regular brake pedal
down with your right foot and push the parking brake
pedal down with your left foot.

2-40
Shifting Into PARK (P)
(Automatic Transmission Only)
CAUTION:
It can be 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. 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, use the steps that
follow. If you're pulling a trailer, see ªTowing a
Trailerº in the Index.
To shift into PARK (P), use the following steps:
1. Hold the brake pedal down with your right foot.2. Move the shift lever into PARK (P) like this:

Press the button on the front of the shift lever as you
push the shift lever all the way toward the front of
your vehicle into PARK (P). Release the button.

With your right foot still holding the brake pedal
down, set the parking brake with your left foot. See
ªParking Brakeº in the Index for more information.
3. Turn the key to OFF.
4. Remove the key from the ignition switch and take it
with you. If you can leave your vehicle with the key
in your hand, the vehicle is in PARK (P).

2-41
Leaving Your Vehicle With the Engine
Running (Automatic Transmission Only)
CAUTION:
It can be dangerous to leave your vehicle with the
engine running. Your vehicle could move
suddenly if the shift lever is not fully in PARK (P)
with the parking brake firmly set. And, if you
leave the vehicle with the engine running, it could
overheat and even catch fire. You or others could
be injured. Don't leave your vehicle with the
engine running unless you have to.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is firmly set before you leave it. After
you've moved the shift lever into PARK (P), hold the
regular brake pedal down. Then, see if you can move the
shift lever away from PARK (P) without first pushing
the button on the shift lever. If you can, it means that the
shift lever wasn't fully locked into PARK (P).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you don't shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transmission. You may find it difficult to pull the
shift lever out of PARK (P). This is called ªtorque lock.º
To prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave the
driver's seat. To find out how, see ªShifting Into
PARK (P)º in the Index.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the parking pawl in the transmission, so
you can pull the shift lever out of PARK (P).
