Engine Coolant Heater
Your vehicle may have an engine coolant heater.
In very cold weather, 0°F (−18°C) or colder,
the engine coolant heater can help. You will 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.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord is located on the driver’s
side of the engine, behind the transaxle
dipstick/ uid ll location and next to the
engine.
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 re. You could
be seriously injured. Plug the cord into a
properly grounded three-prong 110-volt AC
outlet. If the cord will not 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 do not, 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 will be parking your vehicle. The
dealer/retailer can give you the best advice for that
particular area.

Automatic Transaxle Operation
The automatic transaxle may have a shift lever
located either on the steering column or on
the console between the seats.
There are several different positions for the shift
lever.
PARK (P):This position locks the front wheels. It
is the best position to use when you start the
engine because your vehicle cannot 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 rmly set. Your
vehicle can roll.
Do not 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 will not
move, even when you are on fairly level
ground, always set your parking brake
and move the shift lever to PARK (P). See
Shifting Into Park (P) on page 126.Ifyou
are pulling a trailer, seeTowing a Trailer
on page 342.
122
Page 123 of 518

Make sure the shift lever is fully in PARK (P)
before starting the engine. Your vehicle has an
automatic transaxle shift lock control system. You
have to fully apply your regular brakes before
you can shift from PARK (P) while 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) as you
maintain brake application. Then move the shift
lever into another gear. SeeShifting Out of
Park (P) on page 129.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your
vehicle is moving forward could damage the
transaxle. The repairs would not be covered by
your warranty. Shift to REVERSE (R) only after
your vehicle is stopped.
Also use this gear to rock your vehicle back and
forth to get out of snow, ice or sand without
damaging your transaxle. SeeIf Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 332for
additional information.NEUTRAL (N):In this position, the engine does
not connect with the wheels. To restart when
you are already moving, use NEUTRAL (N) only.
Also, use NEUTRAL (N) when your vehicle is
being towed.
{CAUTION:
Shifting into a drive gear while your
engine is running at high speed is
dangerous. Unless your foot is rmly on
the brake pedal, your vehicle could move
very rapidly. You could lose control and
hit people or objects. Do not shift into a
drive gear while your engine is running at
high speed.
Notice:Shifting out of PARK (P) or
NEUTRAL (N) while the engine is running at
high speed may damage the transaxle.
The repairs would not be covered by your
warranty. Be sure the engine is not running at
high speeds when shifting your vehicle.

DRIVE (D):This position is for normal driving. It
provides the best fuel economy for your vehicle. If
you need more power for passing, and you are:
Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push
the accelerator all the way down.
The transaxle will shift down to the next gear
and have more power.
Downshifting the transaxle in slippery road
conditions could result in skidding, see Skidding
underLoss of Control on page 317.
Notice:Driving your vehicle if you notice that it
is moving slowly or not shifting gears as you
increase speed may damage the transaxle. Have
your vehicle serviced right away. You can drive
in SECOND (2) when you are driving less than
35 mph (55 km/h) and DRIVE (D) for higher
speeds until then.DRIVE (D) can be used for towing. You may want
to shift the transaxle to THIRD (3) or, if necessary,
to a lower gear if the transaxle shifts too often under
heavy loads and/or hilly conditions.
SeeTowing a Trailer on page 342for more
information.
THIRD (3):This position is also used for normal
driving. However, it reduces vehicle speed
more than DRIVE (D) without using your brakes.
You might choose THIRD (3) instead of DRIVE (D)
when driving on hilly, winding roads, when
towing a trailer, so there is less shifting between
gears and when going down a steep hill.
SECOND (2):This position reduces vehicle speed
more than THIRD (3) without using your brakes.
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.
Notice:Do not shift into SECOND (2) unless
you are going slower than 65 mph (105 km/h), or
you can damage your engine and/or transaxle.
124
Page 125 of 518

FIRST (1):This position reduces vehicle speed
even more than SECOND (2) without using your
brakes. You can use it on very steep hills, or in
deep snow or mud. If the shift lever is put in
FIRST (1) while the vehicle is moving forward, the
transaxle will not shift into rst gear until the vehicle
is going slowly enough.
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only the
accelerator pedal may damage the transaxle. If
you are stuck, do not spin the tires. When
stopping on a hill, use the brakes, or parking
brake to hold the vehicle in place.
Performance Shifting
If your vehicle has this feature, it can detect a
change in driving patterns. If you make an
aggressive driving maneuver, the vehicle’s
transaxle automatically shifts to the lowest possible
gear to maximize vehicle performance. The
vehicle will automatically return to normal operation
when you return to normal driving patterns.
Parking Brake
The parking brake pedal
is located to the left of
the regular brake pedal,
near the driver’s door.
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.
If the ignition is on, the brake system warning light
on the instrument panel cluster should come
on. If it does not, you need to have your vehicle
serviced.
125
Page 126 of 518

A warning chime will sound if the parking brake is
set, the ignition is on, and the vehicle speed is
greater than 5 mph (8 km/h). The brake light
will come on and stay on until the parking brake is
released. SeeBrake System Warning Light on
page 229for more information.
To release the parking brake, hold the regular
brake pedal down with your right foot and push the
parking brake pedal down with your left foot.
When you lift your left foot, the parking brake pedal
will follow it to the released position.
Notice:Driving with the parking brake on can
overheat the brake system and cause
premature wear or damage to brake system
parts. Verify that the parking brake is fully
released and the brake warning light is
off before driving.
If you are towing a trailer and are parking on any
hill, seeTowing a Trailer on page 342.Shifting Into Park (P)
{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 rmly
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 will not move,
even when you are on fairly level ground,
use the steps that follow. If you are
pulling a trailer, seeTowing a Trailer on
page 342.

use the following procedure to shift the vehicle into
PARK (P):
1. Hold the brake pedal down with your right foot.
2. Move the shift lever into PARK (P) by pulling
the shift lever toward you and moving it up as
far as it will go.
3. With your right foot still holding the brake
pedal down, set the parking brake. See
Parking Brake on page 125for more
information.
4. Turn the ignition key to OFF.
5. 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).
Console Shift Lever
If your vehicle is equipped with a console shift
lever, use the following procedure to shift
the vehicle into PARK (P):
1. Hold the brake pedal down with your right foot.
2. Move the shift lever into PARK (P) by pushing
the lever all the way toward the front of your
vehicle and then to the left.
3. With your right foot still holding the brake
pedal down, set the parking brake. See
Parking Brake on page 125for more
information.
4. Turn the ignition key to OFF.
5. 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
{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 rmly set. And, if you leave the
vehicle with the engine running, it could
overheat and even catch re. You or
others could be injured. Do not leave your
vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P)
and your parking brake is rmly set before you
leave it. SeeParking Brake on page 125for more
information.
Torque Lock
If you are parking on a hill and you do not 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 nd 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 nd out how, seeShifting
Into Park (P) on page 126.
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).
128

Shifting Out of Park (P)
Your vehicle has an automatic transaxle shift lock
control system. You have to fully apply your
regular brakes before you can shift from PARK (P)
when the ignition is RUN. SeeAutomatic
Transaxle Operation on page 122.
The shift lock control system is designed to do the
following:
Prevent the ignition key from being removed
unless the shift lever is in PARK (P).
Prevent movement of the console shift lever
out of PARK (P) unless the ignition is in a
position other than OFF.
The shift lock control system is always functional
except in the case of a dead battery or low
voltage (less than 9 V) battery.
If you cannot shift out of PARK (P), ease the
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.
If you are still having a problem shifting, then have
your vehicle serviced soon.
Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot
exhaust parts under your vehicle and
ignite. Do not park over papers, leaves, dry
grass, or other things that can burn.
