Shifting Into Park
{CAUTION:
It can be 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. 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, use the steps that follow.
If you are pulling a trailer, seeTowing a Trailer
on page 4-55.
1. Hold the brake pedal down and set the parking
brake. SeeParking Brake on page 2-42for more
information.
2. Move the shift lever into P (Park) by pressing the
button on the shift lever and pushing the lever all
the way toward the front of the vehicle.
3. Turn the ignition key to LOCK/OFF.
4. Remove the key and take it with you. If you can
leave the vehicle with the key, the vehicle is in
P (Park).
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 the vehicle is in P (Park) and the parking
brake is rmly set before you leave it. After you have
moved the shift lever into P (Park), hold the regular
brake pedal down. Then, see if you can move the shift
lever away from P (Park) without rst pressing the
button on the console shift lever. If you can, it means
that the shift lever was not fully locked into P (Park).
2-43

Torque Lock
If you are parking on a hill and you do not shift the
transmission into P (Park) 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 P (Park). This is called “torque lock.”
To prevent torque lock, set the parking brake and
then shift into P (Park) properly before you leave the
driver seat. To nd out how, seeShifting Into Park
on page 2-43.
When you are ready to drive, move the shift lever out of
P (Park) before you release the parking brake.
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 P (Park).
Shifting Out of Park
The vehicle is equipped with 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) with the shift lever button fully
released, and
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.
The shift lock release is always functional except in the
case of an uncharged or low voltage (less than 9 volt)
battery.
If the vehicle has an uncharged battery or a battery with
low voltage, try charging or jump starting the battery.
SeeJump Starting on page 5-42for more information.
To shift out of P (Park):
1. Apply the brake pedal.
2. Press the shift lever button.
3. Move the shift lever to the desired position.
If you still are unable to shift out of P (Park):
1. Fully release the shift lever button.
2. While holding down the brake pedal, press the shift
lever button again.
3. Move the shift lever to the desired position.
If you still cannot move the shift lever from P (Park),
see your dealer/retailer.

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 2-45.

feature on or off.
Your vehicle may also have a Rear Vision Camera.
SeeRear Vision Camera (RVC) on page 2-50for more
information.
Cleaning the Mirror
Do not spray glass cleaner directly on the mirror.
Use a soft towel dampened with water.
Outside Power Foldaway Mirrors
If your vehicle has outside
power foldaway mirrors,
the controls are located on
the driver’s door armrest.
Mirror Adjustment
1. Press (A) or (B) to select the driver or passenger
side mirror.
2. Press one of the four arrows located on the control
pad to move the mirror to the desired position.

2-47

4. Press (C), to fold the mirrors out to the driving
position.
5. Press (D) to fold the mirrors in to the folded
position.
If the mirrors are accidentally folded/unfolded manually,
they may shake or utter at normal driving speeds
and may not stay in the unfolded position. If this
happens, you will need to reset the mirrors.
See “Resetting the Power Foldaway Mirrors” next.
Resetting the Power Foldaway Mirrors
You will need to reset the power foldaway mirrors if the
following occurs:
The mirrors are accidentally obstructed while
folding.
They are accidentally manually folded/unfolded.
The mirrors will not stay in the unfolded position.
The mirrors shake and utter at normal driving
speeds.
To reset the power foldaway mirrors, fold and unfold
them three times using the mirror controls. This will reset
them to their normal position.
Outside Automatic Dimming Mirror
If the vehicle has this feature, the driver outside
mirror adjusts for the glare of the headlamps behind
you. SeeAutomatic Dimming Rearview Mirror on
page 2-47for more information.
Park Tilt Mirrors
The vehicle’s outside mirrors can also perform a park tilt
function. This causes the passenger and/or driver’s mirror
to tilt to a preselected position when the vehicle is in
R (Reverse). This feature may be useful in viewing the
curb when parallel parking.
When the vehicle is shifted out of R (Reverse) and a
short delay has occurred, the passenger and/or driver’s
mirror will return to its original position.
To change the preselected tilt position, adjust the
mirrors to the desired position while the vehicle is
in R (Reverse). When the vehicle is shifted out of
R (Reverse), this new position is saved in memory
as the tilt position.
This feature can be enabled/disabled through the Driver
Information Center. SeeDIC Vehicle Customization
on page 3-64for more information.
2-48

Outside Convex Mirror
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you could
hit a vehicle on the right. Check the inside mirror
or glance over your shoulder before changing
lanes.The passenger side mirror is convex shaped. A convex
mirror’s surface is curved so more can be seen from
the driver seat.
Outside Heated Mirrors
The vehicle may have outside heated mirrors which
help clear them of condensation, snow, and ice.
When the rear window defogger button is pressed, the
heated mirrors are also turned on. See “Rear Window
Defogger” underDual Automatic Climate Control System
on page 3-22for more information.

Object Detection Systems
Rear Vision Camera (RVC)
This vehicle may have a Rear Vision Camera system.
Read this entire section before using it.
{CAUTION:
The Rear Vision Camera (RVC) system does not
replace driver vision. RVC does not:
Detect objects that are outside the camera’s
eld of view, below the bumper, or
underneath the vehicle.
Detect children, pedestrians, bicyclists,
or pets.
CAUTION: (Continued)
CAUTION: (Continued)
Do not back the vehicle by only looking at the rear
vision camera screen, or use the screen during
longer, higher speed backing maneuvers or where
there could be cross-traffic. Your judged distances
using the screen will differ from actual distances.
So if you do not use proper care before backing
up, you could hit a vehicle, child, pedestrian,
bicyclist, or pet, resulting in vehicle damage,
injury, or death. Even though the vehicle has
the RVC system, always check carefully before
backing up by checking behind and around the
vehicle.
Vehicles Without Navigation System
The rear vision camera system is designed to help the
driver when backing up by displaying a view of the area
behind the vehicle. When the key is in the ON/RUN
position and the driver shifts the vehicle into R (Reverse),
the video image automatically appears on the inside rear
view mirror. Once the driver shifts out of R (Reverse),
the video image automatically disappears from the inside
rear view mirror.
