{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). SeeShifting Into Park (P) on
page 2-30. If you are pulling a trailer, see
Towing a Trailer on page 4-38.
Ensure 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 the gear you wish. SeeShifting Out of Park
(P) on page 2-32.
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 4-30for additional information.
2-27

THIRD (3):This position is also used for normal driving,
however, it offers more power and lower fuel economy
than AUTOMATIC OVERDRIVE (D). You should
use THIRD (3) when towing a trailer, carrying a heavy
load, driving on steep hills or winding roads.
Here are examples for using THIRD (3) instead of
AUTOMATIC OVERDRIVE (D):
When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
between gears.
When going down a steep hill.
SECOND (2):This position gives you more power than
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.
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.FIRST (1):This position gives you even more power
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, 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.
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.
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 3-62for more information.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 4-38.
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 4-38.

Steering Column Shift Lever
If your vehicle has a steering column 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 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. SeeParking Brake
on page 2-30for 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. SeeParking Brake
on page 2-30for 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. See
Parking Brake on page 2-30for more information.
2-31

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 2-30.
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 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 2-26.
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. Press
the shift lever button and then move the shift lever
into the gear you want.
If you are still having a problem shifting, then have your
vehicle serviced soon.

Running the Engine While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-33.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan 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
Winter Driving on page 4-26.
{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. 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 after you move the shift lever to
PARK (P).
Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into Park (P) on page 2-30.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-38.
