Starting Your Engine
Move the shift lever to PARK (P) or NEUTRAL (N). The
engine will not start in any other position. That is a
safety feature. To restart the vehicle when it is already
moving, use NEUTRAL (N) only.
Notice:Do not 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.
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as the
engine gets warm.
Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about 15
seconds between each try to help avoid draining
your battery or damaging your starter.
2. If it does not start within 10 seconds, hold the key in
START for about 10 seconds at a time until the
engine starts. Wait about 15 seconds between each
try.3. If the engine still will not start, or starts but then
stops, it could be ooded with too much gasoline.
Try pushing the accelerator pedal all the way to the
oor and holding it there as the key is held in
START for about three seconds. If the vehicle starts
briey but then stops again, do the same thing.
This time keep the pedal down for ve or six
seconds to clear the extra gasoline from the engine.
After waiting about 15 seconds, repeat the normal
starting procedure.
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 do not, your engine
might not perform properly.

Engine Coolant Heater
The vehicle may have this feature. In very cold weather,
0°F (−18°C) or colder, the engine coolant heater can
help. The vehicle will start easier and get 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
cord is attached to the underside of the vehicle’s
diagonal brace, which is located above the engine
air cleaner/lter assembly.
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. Unplug and store the cord as it was before to keep
it away from moving engine parts, before starting
the engine. If this is not done, the cord could
be damaged.
2-20

How long should the coolant heater be kept plugged in?
The answer depends on the outside temperature, the
kind of oil used in the vehicle, and some other
things. Instead of trying to list everything here, contact
your dealer in the area where the vehicle will be parking.
The dealer can give you the best advice for that
particular area.
Automatic Transaxle Operation
The shift lever, located on
the console between the
seats, operates the
automatic transaxle.The ignition positions are displayed on the instrument
panel cluster and will indicate the gear the vehicle is in.
Maximum engine speed is limited on the automatic
transaxle when the vehicle is in PARK (P) or
NEUTRAL (N) to protect driveline components from
improper operation.
2-21

{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 4-39.
The positions for the shift lever are:
PARK (P): This position locks the vehicle’s front
wheels. It is the best position to use when the engine is
started because the vehicle cannot move easily.Make sure the shift lever is fully in PARK (P) before
starting the engine. The vehicle has an automatic
transaxle shift lock control system. You must fully apply
the regular brakes before shifting from PARK (P)
when the ignition is in RUN. If you cannot shift out of
PARK (P), ease pressure on the shift lever by pushing it
all the way into PARK (P) while keeping the brake
pedal pushed down. Release the shift lever button. Then
move the shift lever out of PARK (P). SeeShifting
Out of Park (P) on page 2-27
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.
REVERSE (R): Use this gear to back up.
To rock the vehicle back and forth in order to get it out
of snow, ice or sand without damaging the transaxle,
seeIf You Are Stuck: In Sand, Mud, Ice or Snow
on page 4-30.
2-22

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 the 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)
with the engine racing may damage the transaxle.
The repairs would not be covered by your warranty.
Be sure the engine is not racing when shifting
your vehicle.
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 AUTOMATIC OVERDRIVE (D) for
higher speeds until then.AUTOMATIC OVERDRIVE (
X): This position is for
normal driving. If more power is needed for passing, and
the vehicle is:
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 pedal all the way down.
By doing this the vehicle will automatically shift down to
the next gear and have more power.
THIRD (3):This position is also used for normal driving,
but it offers more power and lower fuel economy than
AUTOMATIC OVERDRIVE (
X).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (
X):
When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
between gears.
When going down a steep hill.
When driving in no-highway scenarios such as city
streets.
2-23

Notice:Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph (90 km/h)
may damage the transaxle. Also, shifting into
SECOND (2) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or AUTOMATIC
OVERDRIVE (D) instead of SECOND (2).
SECOND (2): This position gives the vehicle more
power but lower fuel economy than THIRD (3). You can
use SECOND (2) on hills. It can help control the
speed going down steep mountain roads, but then you
would also want to use the brakes off and on.
FIRST (1): This position gives the vehicle 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 shift lever is put in FIRST (1), 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 to hold the vehicle in place.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.
To release the parking brake, hold the regular brake
pedal down with your right foot and push the parking
brake pedal with your left foot. When you lift your
left foot, the parking brake pedal will follow it to the
released position.
A warning chime will sound if the parking brake is set,
the ignition is on, and the shift lever is not in PARK (P)
or NEUTRAL (N).
2-24

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 parking on any hill, see
Towing a Trailer on page 4-39. That section shows what
to do rst to keep the trailer from moving.
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 4-39.
1. Hold the brake pedal down with your right foot and
set the parking brake with your left foot.2. Move the shift lever
into PARK (P) by
pressing the shift lock
button at the top of
the lever while pushing
the shift 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 the vehicle with the ignition key in your
hand, the vehicle is in PARK (P).
2-25

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 the
parking brake is rmly set before you leave it. After you
have moved the shift lever into PARK (P), hold the
regular brake pedal down. Then, see if you can move
the shift lever out of PARK (P) without rst pushing
the shift lever button. If you can, it means that the shift
lever was not fully locked into PARK (P).
Torque Lock
If the vehicle is parked on a hill and the transaxle is not
shifted into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transaxle. It might be 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 leaving the driver’s
seat. To nd out how, seeShifting Into Park (P) on
page 2-25.
When you are ready to drive, move the shift lever out of
PARK (P)beforeyou release the parking brake.
If torque lock does occur, another vehicle might have to
push yours a little uphill. This takes some of the
pressure off the parking pawl in the transaxle, enabling
the shift lever to be moved out of PARK (P).
2-26

Shifting Out of Park (P)
The vehicle has an automatic transaxle shift lock control
system which locks the shift lever in PARK (P) when the
ignition is in the OFF position. The regular brakes must
be fully applied before the vehicle can be shifted from
PARK (P) when the ignition in RUN. SeeAutomatic
Transaxle Operation on page 2-21.
If the vehicle cannot be shifted out of PARK (P), ease
pressure on the shift lever and push the shift lever all the
way into PARK (P) as brake application is maintained.
Then, move the shift lever into the desired gear.
If the brake pedal is pressed down but the vehicle still
cannot be shifted out of PARK (P), try this:
1. Turn the ignition key to ACCESSORY. There is no
shift interlock in this key position.
2. Apply and hold the brake until the end of Step 4.
3. Shift the transaxle to NEUTRAL (N).
4. Start the engine and then shift to the desired gear.
5. Have the system xed as soon as possible.
Shift Lock Release
The vehicle is equipped with a shift lock release system.
It is designed to prevent ignition key removal unless
the shift lever is in PARK (P) and the shift lever button
is fully released.
It also prevents the shift lever from moving out of
PARK (P) when the ignition is in OFF or in LOCK. The
shift lock release system will not operate in the case
of a dead or low voltage (less than 9 V) battery.
If the vehicle has a dead battery or a battery with low
voltage, there are two override access slots that
will allow you to override the shift lock release system.
The rst access slot is located underneath the
steering column below the lock cylinder. To use this
slot, do the following:
1. Verify that the shift lever is in PARK (P) with the
shift lever button released.
2. Remove the override access slot cap to show the
override mechanism release button.
3. Insert a key or tool into the access slot and then
press and hold the override mechanism release
button.
4. Turn the ignition key to OFF.
5. Remove the key from the ignition switch.
6. Put the override access slot cap back on.
2-27

The key will not be able to be removed from the ignition
unless the shift lever is in PARK (P) with the shift
lever button fully released.
The second override
access slot is located on
the upper right side of
the console shift panel.
To use this slot, do the following:
1. Remove the override access slot cap.
2. Insert a key or tool into the access slot and press
and hold the override mechanism release button.
3. Move the shift lever into the desired gear position.
4. Put the override access slot cap back on.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.
