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.
P (Park):This position locks the front wheels. It is
the best position to use when you start the engine
because the 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 2-33. If you are pulling a trailer,
seeTowing a Trailer on page 4-28.
Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You have to fully
apply the regular brakes before you can shift from
P (Park) while the ignition key is in ON/RUN. If you
cannot shift out of P (Park), ease pressure on the shift
lever. Push the shift lever all the way into P (Park)
as you maintain brake application. Then move the shift
lever into another gear. SeeShifting Out of Park on
page 2-34.
2-29

Performance Shifting
If the vehicle has this feature, it can detect a change in
driving patterns. If you make an aggressive driving
maneuver, the vehicle’s transmission 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 door.
To set the parking brake, hold the regular brake pedal
down, then push the parking brake pedal down.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 the 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. SeeBrake System
Warning Light on page 3-56for more information.
To release the parking brake, hold the regular brake
pedal down, then push the parking brake pedal down.
When you lift your foot off the parking brake pedal,
the pedal will follow your foot 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 4-28.
2-32

Leaving the Vehicle With the Engine
Running
{CAUTION:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly
if the shift lever is not fully in P (Park) 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 the vehicle with the engine
running.
If you have to leave the vehicle with the engine running,
be sure your vehicle is in P (Park) and the parking
brake is rmly set before you leave it. SeeParking Brake
on page 2-32for more information.
Torque Lock
Torque lock is when the weight of the vehicle puts too
much force on the parking pawl in the transmission.
This happens when parking on a hill and shifting
the transmission into P (Park) is not done properly and
then it is difficult to shift out of P (Park). To prevent
torque lock, set the parking brake and then shift into
P (Park). To nd out how, see “Shifting Into Park” in this
section.
If torque lock does occur, your vehicle may need to be
pushed uphill by another vehicle to relieve the parking
pawl pressure, so you can shift out of P (Park).
Shifting Out of Park
Automatic Transmission Shift Lock
This vehicle has an electronic shift lock release system.
The shift lock release is designed to:
Prevent ignition key removal unless the shift lever
is in P (Park)
Prevent movement of the shift lever out of
P (Park), unless the ignition is in ON/RUN or
ACC/ACCESSORY and the regular brake pedal
is applied.
2-34

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 a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
Monoxide (CO) which cannot be seen or smelled.
It can cause unconsciousness and even death.
Never run the engine in an enclosed area that has
no fresh air ventilation. For more information,
seeEngine Exhaust on page 2-36.
{CAUTION:
It can be dangerous to get out of the vehicle if the
automatic transmission 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 after you move the shift lever
to P (Park).
Follow the proper steps to be sure the vehicle will not
move. SeeShifting Into Park on page 2-33.
If parking on a hill and pulling a trailer, seeTowing a
Trailer on page 4-28.

Headlamps on Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver’s door is opened with the ignition off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional daytime running lamps are required
on all vehicles rst sold in Canada.
The DRL system makes the turn signal lamps come on
when the following conditions are met:
It is still daylight and the ignition is on.
The exterior lamp control is in the off position.
The transmission is not in P (Park)
(United States only).
The light sensor is covered or not detecting light.
See “Sensors” underDual Climate Control System
on page 3-40.
When DRL are on, no other exterior lamps such as the
parking lamps, taillamps, etc. will be on when the DRL
are being used. The instrument panel will not be lit
up either.When automatic lighting is on and it is dark enough
outside, the turn signal lamps turn off and normal
low-beam headlamp operation occurs.
When automatic lighting is on and it is bright enough
outside, the regular lamps go off, and the DRL takes over.
If the vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once you
leave the garage, it will take approximately one minute
for the automatic headlamp system to change to DRL if
there is light outside. During that delay, the instrument
panel cluster may not be as bright as usual. Make sure
the instrument panel brightness knob is in the full bright
position. SeeInstrument Panel Brightness on page 3-34.
Turning on automatic lighting or the headlamps will
deactivate the DRL. If the parking lamps or the fog lamps
were turned on instead, the DRL will still deactivate.
To idle the vehicle with the DRL off at night, turn off
automatic lighting and shift the transmission into P (Park).
Placing the vehicle in P (Park) disables the DRL. The
DRL will stay off until the vehicle is shifted out of P (Park).
To drive the vehicle with the DRL off, turn off automatic
lighting and manually turn on the parking lamps or
fog lamps, if the vehicle has them.
The regular headlamp system should be turned on
when needed.
