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.

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.

NOTICE:
Driving with the parking brake on can cause
your rear brakes to overheat.
You may have to
replace them, and you could also damage other
parts of your vehicle.
If you are towing a trailer and you must park on a hill,
see “Towing
a Trailer” in the Index. That section shows
what to do first to keep the trailer from moving.
Shifting Into PARK (P)
L
I
L!h CAUTL .:
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. Always put the shift lever fully in
PARK
(P) with the parking brake firmly set. If
you’re pulling a trailer, see “Towing a Trailer” in
the Index.
1. Hold the brake pedal down with your right foot and
set the parking brake.
2-21
ProCarManuals.com

2. Move the shift lever into PARK (P) position
like this:
Hold in the button on the lever.
Push the lever all the way toward the front of
the vehicle.
3. Turn the ignition key to LOCK,
4. Remove the key and take it with you. If you can
leave your vehicle with the key, your vehicle
is in
PARK
(P).
Leaving Your Vehicle With the
Engine Running
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 pressing the
button
on the shift lever. If you can, it means that the
shift lever wasn’t fully locked into PARK
(P).

Torque Lock Shifting Out of Park (P)
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 “torque lock.”
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 “Shifting Into PARK
(P)” in the Index.
When you are ready to drive, move the shift lever
out of
PARK (P)
before you release the parking brake.
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). Your
vehicle has
a Brake-Transmission Shift Interlock
(BTSI). You have to fully apply your regular brake
before you
can shift from PARK (P) when the ignition is
in RUN. See “Automatic Transmission Operation”
in
the Index.
If you cannot shift out of PARK (P), ease pressure on
the shift lever
-- push the shift lever all the way into
PARK
(P) as you maintain brake application. Then
move
the shift lever into the gear you want. You must
press the shift lever button on the console shift lever.
If
you ever hold the brake pedal down but still can’t
shift out
of PARK (P), try this:
1. Turn the key to OFF.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear
you want.
5. Have the vehicle fixed as soon as you can.

Running Your Engine While
You’re Parked
It’s better not to park with the engine running. But if
ever you have to, here
are some things to know.
A CAUTION:
Idling the engine with the air system control
off could allow dangerous exhaust into your
vehicle (see the earlier Caution under
“Engine Exhaust”).
Also, idling in
a closed-in place can let deadly
carbon monoxide
(CO) into your vehicle even if
the fan switch is at the highest setting. One place
this can happen
is a garage. Exhaust -- with
CO -- can come in easily. NEVER park in a
garage with the engine running.
Another closed-in place can be
a blizzard. (See
L6BlizzardSS in the Index.)
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.
Don’t leave your vehicle when the engine is
running unless you have to.
If you’ve 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).
Follow the proper steps to be sure your vehicle won’t
move. See “Shifting Into
PARK (P)” in the Index.
If you’re pulling a trailer, see “Towing a Trailer” in
the Index.

Passing Another Vehicle While Using Cruise Control Exterior Lamps
Use the accelerator pedal to increase your speed. When
you take your foot off the pedal, your vehicle will slow
down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the hills.
When going up steep hills, you may want
to step on the
accelerator pedal to maintain your speed. When going
downhill, you may have to brake or shift to a lower gear
to keep your speed down.
Of course, applying the brake
takes you out of cruise control. Many drivers find this to
be too much trouble and don’t use cruise control on
steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:
Step lightly on the brake pedal.
Move the cruise control switch to OFF.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
your cruise control set speed memory is erased. Your
parking lamp and headlamp switch is on the
driver’s side
of your instrument panel.
Rotate the
knob to the right to the parking lamps symbol
to manually turn on:
Parking Lamps
Sidemarker Lamps
Taillamps
License Plate Lamps
Instrument Panel Lights
2-36
ProCarManuals.com

Rotate the knob to the right to the master lamps symbol
to turn on all the lamps listed as well as
the headlamps.
Rotate the
knob all the way to the left to turn off your
lamps and put the system in automatic headlamp mode.
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. The radio lights will also be dim.
Your vehicle is equipped with High Intensity Discharge
(€€ID) headlamps. Your headlamps come on at lower
intensity and gradually increase to full brightness.
Your vehicle is equipped with
a light sensor on the top
of the instrument panel under the radio speaker grille,
so
be sure it is not covered, which will cause the system to
be on whenever the ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather, a tunnel or fueling your vehicle in a low-light
area. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running Lamps
(DRL) and the automatic headlamp systems
so that driving under bridges or bright overhead street lights
does not affect the system. The DRL and automatic
headlamp system will only be affected when the light
sensor
sees a change in lighting lasting longer than
the delay.
To idle your vehicle with the automatic headlamp
system
off, set the parking brake while the ignition is
off. Then start your vehicle. The automatic headlamp
system 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.
Lamps On Reminder
A reminder chime will sound when your headlamps or
parking lamps
are manually turned on and your ignition
is in
OFF, LOCK or ACCESSORY. To disable the
chime, rotate the thumb wheel all the way down. In
the
automatic mode, the headlamps turn off once the
ignition key is in
OFF,
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.
2-37
ProCarManuals.com

The DRL system will make your high-beam headlamps
come
on at reduced brightness when:
Fog Lamps
the ignition is on,
the headlamp switch is in automatic headlamp
mode and
the parking brake is released.
When the DRL are on, only your high-beam headlamps
will be on. The taillamps, sidemarker and other lamps
won’t be on. The instrument panel won’t be lit up either.
When it begins to get dark, the high-beam headlamps
will automatically switch from DRL to the regular
low-beam headlamps.
When you turn
the headlamp switch off, the regular
low-beam headlamps will
go off, and your high-beam
headlamps will change to the reduced brightness
of DRL
provided it is not dark outside.
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. Use your fog lamps
for better vision in foggy or misty
conditions. Your low-beam headlamps or your parking
lamps must be on for your fog lamps to work.
The fog lamp switch is
on the instrument panel under
the lamps switch. Press
the switch to turn the fog lamps
on. Press the switch again to turn them
off. A light will
glow in
the switch when the fog lamps are on.
Remember,
fog lamps alone will not give off as much
light as your headlamps. Never use your fog lamps in
the dark without turning on your headlamps.
The
fog lamps will go off whenever your high-beam
headlamps come on. When the high beams
go off, the
fog lamps will come on again.
