stored setting. Each time a memory button is pressed, a
single beep will sound.
Three chimes will sound and the setting will not be
recalled if you press button 1 or 2 while the engine is
running and the vehicle is not in PARK (P) on an
automatic transmission or the parking brake is not
set on a manual transmission.
If you would like the stored driving positions to be
recalled when unlocking your vehicle with the remote
keyless entry transmitter or when you place the key in
the ignition, see ªVehicle Programming and
Personalization Featuresº in the Index.

memory seat button 2 or the remote keyless entry
transmitter with the number 2 on the back.To recall the stored exit positions, press and release the
exit button. One beep will sound, and the seat will move
to the previously stored exit position for the currently
identified driver. If an exit position has not been stored
for this driver, the seat will move all the way back. The
position of the outside mirrors is not stored or recalled
for the exit position.
If your vehicle has an automatic transmission, the
vehicle must be in PARK (P) to recall the exit positions.

when unlocking the vehicle with the remote keyless
entry transmitter or when the ignition is turned off and
the driver's door is opened, see ªVehicle Programming
and Personalization Featuresº in the Index.

Automatic Door Locks
If your vehicle has an automatic transmission, your
vehicle is programmed so that when the doors are
closed, the ignition is on and the shift lever is moved out
of PARK (P), all the doors will lock. The doors will
unlock every time you stop the vehicle and move the
shift lever back into PARK (P).
If your vehicle has a manual transmission, the doors
will lock automatically after the vehicle speed reaches
5 mph (8 km). The doors will not automatically unlock
until the ignition is turned off and the key is removed
from the ignition switch.
If someone needs to exit the vehicle once the doors have
locked, have that person use the manual lever or power
door lock switch. When the door is closed again, it will
not lock automatically. Use the manual lever or power
lock switch to lock the door.
Programmable Automatic Door Locks
The power door locks can be programmed through
prompts displayed on the Driver Information Center
(DIC). These prompts allow you to choose various
lock and unlock settings. For more information on
programming, see ªVehicle Programming and
Personalization Featuresº in the Index.
Rear-Door Security Locks
Your vehicle is equipped with rear door security locks
that prevent passengers from opening the rear doors on
your vehicle from the inside.
The rear door security locks
are located on the inside
edge of each rear door. You
must open the rear doors to
access them.
To use these locks, do the following:
1. Insert your key into the slot next to the rear door
security lock label and turn it to engage the lock.
2. Close the door.
3. Repeat the steps for the other rear door.
The rear doors on your vehicle cannot be opened from
the inside when this feature is in use.

2-16
Trunk Lid
CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even death.
If you must drive with the trunk lid open or if
electrical wiring or other cable connections must
pass through the seal between the body and the
trunk lid:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See ªComfort Controlsº
in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
Remote Trunk Release Button
The remote trunk release
button is located on the
lower portion of the
driver's door.
To use this feature, an automatic transmission must
be in PARK (P) or NEUTRAL (N) and your manual
transmission must be in NEUTRAL with the parking
brake set.
Press the button to open the trunk. You can also press
the button with the trunk symbol on the remote keyless
entry transmitter to open the trunk.
When the trunk lid opens, a light inside the trunk
will come on. The light will go out when the trunk
lid is closed.

2-25
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.

2-28
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.

2-37
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.
