Automatic Transmission Operation
The automatic transmission 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 the vehicle if the
shift lever is not fully in P (Park) with the
parking brake rmly set. The vehicle can roll.
Do not leave the 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 the
vehicle will not move, even when you are on
fairly level ground, always set the parking brake
and move the shift lever to P (Park). SeeShifting
Into Park on page 2-31. If you are pulling a
trailer, seeTowing a Trailer on page 4-27.
Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission 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 ON/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 on
page 2-33.
2-27

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.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. See
Brake System Warning Light on page 3-60for 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. Make sure
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 4-27.
2-30

Shifting Into Park
{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 4-27.
Steering Column Shift Lever
If your vehicle has a steering column shift lever, use this
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 LOCK/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 this 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 LOCK/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).
2-31

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.
Torque Lock
If you are parking on a hill and you do not 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 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 on page 2-31.
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).
2-32

Running the Vehicle 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 2-34.
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.
Also see “If You Are Caught in a Blizzard” under
Winter Driving on page 4-16.
{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 the 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 on page 2-31.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-27.
2-35

When the System Does Not Seem to
Work Properly
The driver disables the system.
The parking brake pedal is depressed.
The ultrasonic sensors are not kept clean. So be
sure to keep your vehicle’s front and rear bumpers
free of mud, dirt, snow, ice and slush. For cleaning
instructions, seeWashing Your Vehicle on
page 5-94.
A trailer was attached to your vehicle, or a bicycle or
an object was hanging out of your trunk during your
last drive cycle, the red light may illuminate in the
rear display. Once the attached object is removed,
UFRPA will return to normal operation.
A tow bar is attached to your vehicle.
The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled after driving forward at
least 15 mph (25 km/h), take your vehicle to your
dealer/retailer.
