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. With four-wheel drive,
your vehicle will be free to roll — even if your
shift lever is in PARK (P) — if your transfer
case is in NEUTRAL. So, be sure the transfer
case is in a drive gear — not in NEUTRAL.
SeeFour-Wheel Drive on page 2-26. Always
put the shift lever fully in PARK (P) with the
parking brake rmly set. If you are pulling a
trailer, seeTowing a Trailer on page 4-55.To shift into PARK (P), do the following:
1. Hold the brake pedal down with your foot and set
the parking brake.
2. Move the shift lever
into PARK (P) like this:
3. Press the button in on the side of the lever.
4. Push the lever all the way toward the front of the
vehicle.
5. Turn the ignition key to LOCK.
6. Remove the key and take it with you. You know
your vehicle is in PARK (P) if the key can be
removed from the ignition.

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.
If you have four-wheel drive, your vehicle will be
free to roll – even if your lever is in PARK (P) – if
your transfer case is in NEUTRAL. So be sure
the transfer case is in a drive gear – not
NEUTRAL. See “Four-Wheel Drive (Automatic
Transfer Case)” in the Index.
And, if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Don’t leave
your vehicle with the engine running unless
you have to.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. After
you’ve moved the shift lever into PARK (P), hold
the regular brake pedal down. Then, see if you can
move the shift lever away from PARK (P) without rst
pressing the button on the console shift lever. If you can,
it means that the shift lever wasn’t fully locked into
PARK (P).
Torque Lock
If you are parking on a hill and you don’t 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 (P) on page 2-31.
When you are ready to drive, move the shift lever out of
PARK (P)beforeyou 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 PARK (P).

Shifting Out of Park (P)
Your vehicle has an automatic transmission shift lock
control system. You have to fully apply the regular
brakes before you can shift from PARK (P) when the
ignition is in RUN. SeeAutomatic Transmission
Operation on page 2-24.
Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Do not
park over papers, leaves, dry grass or other
things that can burn.

Luggage Carrier
{CAUTION:
If you try to carry something on top of your
vehicle that is longer or wider than the luggage
carrier — like paneling, plywood, a mattress and
so forth — the wind can catch it as you drive
along. This can cause you to lose control.
What you are carrying could be violently torn
off, and this could cause you or other drivers to
have a collision, and of course damage your
vehicle. You may be able to carry something like
this inside. But, never carry something longer
or wider than the luggage carrier on top of your
vehicle.
A luggage carrier allows you to load things on top of
your vehicle. The luggage carrier has side rails attached
to the roof, sliding crossrails (if equipped) and places
to use for tying things down. These let you load
some other things on top of your vehicle, as long as
they are not wider or longer than the luggage carrier.To slide the crossrails to where you want them, pull up
on the lever on each side of the crossrail. This will
release the crossrail and allow you to slide it. When the
crossrail is where you want it, press down on the
levers to lock it into place.
Notice:Loading cargo on the luggage carrier that
weighs more than 220 lbs (100 kg) or hangs over the
rear or sides of the vehicle may damage your vehicle.
Load cargo so that it rests on the slats as far forward
as possible and against the side rails, making sure to
fasten it securely.
Don’t exceed the maximum vehicle capacity when
loading your vehicle. For more information on vehicle
capacity and loading, seeLoading Your Vehicle on
page 4-49.
To prevent damage or loss of cargo as you’re driving,
check now and then to make sure the luggage carrier is
locked and cargo is still securely fastened.
When the luggage carrier is not in use, place the
crossrails at the following positions for wind noise
reduction. Place one crossrail at the rear most point of
the vehicle and the other crossrail above the opening
of the rear door.
