Shifting Into Park
(Automatic Transmission)
{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 4-42.
1. Hold the brake pedal down,
then set the parking brake.
SeeParking Brake on page 2-28
for more information.
{CAUTION
With all-wheel drive, the vehicle
will be free to roll — even if the
shift lever is in P (Park) — if the
transfer case is in Neutral. So, be
sure the transfer case is in a drive
gear, four-wheel high (4H) or
four-wheel low (4L) — not in
Neutral.
2. Move the shift lever into P (Park)
by pressing the shift lever button
and moving the lever as far
forward as it will go.
3. Turn the ignition key to
LOCK/OFF.
4. Remove the key from the
ignition.
Leaving Your Vehicle
With the Engine Running
(Automatic Transmission)
{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.
Features and Controls 2-29

Then, see if you can move the shift
lever away from P (Park) without
rst pressing the shift lever button.
If you can, it means that the
shift lever was not fully locked into
P (Park).
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 P (Park)” listed
previously.
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)
This 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
a 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 5-34for more information.To shift out of P (Park):
1. Apply the brake pedal.
2. Then 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), consult your
dealer/retailer or a professional
towing service.

inside rear view mirror. Read this
entire section before using the
camera system.
When the key is in the ON/RUN
position and the driver shifts the
vehicle into R (Reverse), the video
image appears from inside the
rear view mirror. Once the vehicle
is shifted out of R (Reverse),
the image disappears.
The display may have a guideline

Detect objects that are
outside the camera’s eld of
view, below the bumper, or
underneath the vehicle.
Detect children, pedestrians,
bicyclists, or pets.
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.

siderails attached to the roof.
The crossrails attach into the
siderails and can be moved back
and forth to accommodate various
cargo sizes.
Notice:Loading cargo on the
luggage carrier that weighs more
than 250 lbs. (113 kg) or hangs
over the rear or sides of the
vehicle may damage the vehicle.
Load cargo only on top of the
crossrails and tie the cargo down
to the crossrail support cargo
tie-down loops, making sure
to fasten it securely
Do not exceed the maximum vehicle
capacity when loading your vehicle.
For more information on vehicle
capacity and loading, seeLoading
the Vehicle on page 4-35.Adjusting the Crossrails

being moved past the opening of
the sunroof and cargo from
being loaded too far forward.
The vehicle may have cargo tie
downs. Once the cargo is loaded
onto the crossrails, use the cargo tie
downs to secure it. Do not load
cargo directly on the roof of the
vehicle. SeeCargo Tie Downs on
