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.

the windshield can be washed, but
the rear windows cannot.
Cruise Control
With cruise control, a speed of
about 25 mph (40 km/h) or more can
be maintained without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below about 25 mph (40 km/h).
9(Off):Turns the cruise control

Cruise control will not work if the
parking brake is set, or if the master
cylinder brake uid level is low.
If the brakes are applied, the cruise
control shuts off.
{CAUTION
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
The cruise control disengages, if the
vehicle has the Traction Control
System (TCS) and it begins to limit
wheel spin. SeeTraction Control
System (TCS) on page 4-7.
When road conditions allow the
cruise control to be safely used
again, you can turn it back on.
Instrument Panel 3-9

Setting Cruise Control
{CAUTION
If you leave your cruise control on
when you are not using cruise,
you might hit a button and go into

Suppose the cruise control is set at
a desired speed and then you
apply the brake or step on the
clutch. This disengages the cruise
control. But it does not need to
be reset.
Once the vehicle is going about
25 mph (40 km/h) or more, move
the cruise control switch briey
from
RtoS.
The vehicle goes back to the
chosen speed and stays there.
If the switch is held at
resume/accelerate the vehicle will
keep going faster until the switch is
released or the brake is applied.
Do not hold the switch at
resume/accelerate, unless you want
the vehicle to go faster.Increasing Speed While Using
Cruise Control
There are two ways to go to a
higher speed:
Use the accelerator pedal to get
to the higher speed. Press
T
at the end of the lever, then
release the button and the
accelerator pedal. The vehicle
will now cruise at the higher
speed. If the accelerator pedal is
held longer than 60 seconds,
cruise control will turn off.
Move the cruise switch fromRto
S. Hold it there until you get up
to the desired speed, and
then release the switch. To
increase the vehicle speed in
small amounts, move the switch
briey to resume/accelerate.
Each time this is done, the
vehicle goes about 1 mph
(1.6 km/h) faster.
