Engine Coolant Heater (If Equipped)
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
110-volt
AC outlet. If the cord won’t reach, use
a heavy-duty three-prong extension cord rated
for
at least 15 amps.
In very cold weather,
0 OF (- 18 O 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.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 1 10-volt AC outlet.
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 retailer
in the area where you’ll be parking your
vehicle.
The retailer can give you the best advice for
that particular area.

Automatic Transaxle Operation
There are several different positions for your shift lever.
PARK (P): This position locks your front 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 the PARK (P)
range before starting the engine. Your vehicle has a
brake-transaxle shift interlock. You have to fully
apply
your regular brakes bcfore you can shift from PARK (P)
when the ignition key is in RUN.
2-24

REVERSE (R): Use this gear to back up.
I NOTICE:
Shifting to REVERSE (R) while your vehicle is
moving forward could damage your transaxle. 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 transaxle, see
“Stuck: In Sand, Mud, Ice or Snow” in the Index.
NEUTRAL
(N): In this position, your engine doesn’t
connect with the wheels.
To restart when you’re
already moving, use
NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed. Shifting out
of PARK
(P) or NEU‘l’RAL (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.
I NOTICE:
Damage to your transaxle caused by shifting out
of PARK (P) or NEUTRAL (N) with the engine
racing isn’t covered by your warranty.
2-25

AUTOMATIC OVERDRIVE (0): This position is
for normal driving. If you need more power for passing,
and you’re:
Going less than approximately 35 mph (55 km/h),
push your accelerator pedal about halfway down.
Going about 35 mph (55 kmh) or more, push the
accelerator all the way down.
You’ll shift down to the next gear and have more power.
THIRD (3): This position is also used for normal
driving, however, it
offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE
(0). Here
are some times you might choose THIRD
(3) instead
of AUTOMATIC OVERDRIVE
(@):
When driving on hilly, winding roads,
When towing a trailer, so there is less shifting
When going down a steep hill.
SECOND (2): This position gives you more power
but lower fuel economy than AUTOMATIC
OVERDRIVE
(a) or 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.
between gears,
or
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 (l), the transaxle
won’t shift into FIRST
(1) until the vehicle is going
slowly enough.
NOTICE:
If your front 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 transaxle.
Also, if you stop when going uphill, don’t hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transaxle. Use your brakes or shift into
PARK (P)
to hold your vehicle in position on a hill.

Selectable Shift
This button lets you change from a normal driving mode
to a power mode. For general driving conditions, use the
normal mode.
Parking Brake
Press the button on your shift lever so that it’s either in
the NORMAL or the
POWER position. When it’s in the
NORMAL position, the line on the button will be
showing. When in POWER, the line is not showing.
In the NORMAL position, the transaxle shifts at lower
engine speeds. For increased performance, you may
choose the POWER mode.
Setting 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
parking brake indicator light will come on.

Releasing the parking brake: You will need to use the
PUSH TO RELEASE parking brake pedal. Hold the
regular brake down and push the parking brake pedal
with your left foot. This will unlock the pedal. When
you lift your left foot, the parking brake pedal will
follow
it to the released position.
If you try to drive with the parking brake on, the parking
brake indicator light stays
on. The PARK BRAKE SET
message will appear in the Driver Information Center,
and
a chime will sound until you release the parking
brake or recycle the ignition.
NOTICE:
Shifting Into PARK (P)
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 are parking on any hill,
see “Towing a Trailer” in the Index. That part
shows
what to do first to keep the trailer from moving.
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 “Towing a
Trailer” in the Index.
1. Hold the brake pedal down with your right foot and
set the parking brake by pushing down the parking
brake pedal with your left foot.
2-28

2. Move the shift lever into PARK (P) as follows:
Hold in the button on the lever.
Push the lever all the way down toward the front
of your 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 ignition key in your
hand, 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 first pushing
the button.
If you can, it means the shift lever wasn’t fully locked
into PARK (P).

Torque Lock
If you are parking on a hill and you don’t shift your
transaxle into PARK
(P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transaxle. 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 transaxle,
so you
can pull the shift lever out
of PARK (P).
Shifting Out of PARK (P)
Your vehicle has a brake-transaxle shift interlock. You
have to fully
apply your regular brake before you can
shift from PARK (P) when the ignition
is in RUN. See
“Shifting the Automatic Transaxle” 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 wish. Press the
shift lever button before moving the shift lever.
If you ever hold the brake pedal down but still can’t
shift out
of PARK (P), try this:
1. Turn the ignition key to OFF. Open and close the
driver’s door
to turn off the retained accessory
power feature.
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. Take your vehicle to an authorized service center
as soon as you can.
