NOTE:
On four-wheel drive vehicles be sure that the
transfer case is in a drive position.
When exiting the vehicle, always:
Apply the parking brake.
Shift the transmission into PARK.
Turn the engine off.
Remove the key fob.
WARNING!
Never use the PARK position as a substi
-
tute for the parking brake. Always apply the
parking brake fully when exiting the vehicle
to guard against vehicle movement and
possible injury or damage.
Your vehicle could move and injure you and
others if it is not in PARK. Check by trying to
move the gear selector out of PARK with the
brake pedal released. Make sure the trans -
mission is in PARK before exiting the
vehicle.
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing
the brake pedal, the vehicle could accel -
erate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and your
foot is firmly pressing the brake pedal.
Unintended movement of a vehicle could
injure those in or near the vehicle. As with
all vehicles, you should never exit a vehicle
while the engine is running. Before exiting a
vehicle, always come to a complete stop,
then apply the parking brake, shift the
transmission into PARK, turn the engine
OFF, and remove the key fob. When the
ignition is in the LOCK/OFF (key removal)
position (or, with Keyless Enter-N-Go, when
the ignition is in the OFF mode), the trans -
mission is locked in PARK, securing the
vehicle against unwanted movement.
When leaving the vehicle, always make
sure the ignition is in the OFF mode,
remove the key fob from the vehicle, and
lock the vehicle.
WARNING! (Continued)
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seriously
or fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the transmission gear
selector.
Do not leave the key fob in or near the
vehicle (or in a location accessible to chil -
dren), and do not leave the ignition (in a
vehicle equipped with Keyless Enter-N-Go)
in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or
move the vehicle.
CAUTION!
Before moving the transmission gear
selector out of PARK, you must turn the igni -
tion to the ON/RUN mode, and also press
the brake pedal. Otherwise, damage to the
gear selector could result.
WARNING! (Continued)

290STARTING AND OPERATING
Shifting Into N (Neutral)
Use the following procedure to prepare your
vehicle for recreational towing.
1. Bring the vehicle to a complete stop on
level ground, with the engine running.
Firmly apply the parking brake.

2. Shift the transmission to NEUTRAL.
3. Press and hold the brake pedal.
4. Shift the transfer case into N (Neutral):
With manual shift transfer case, shift the transfer case lever into N (Neutral).
With electronic shift transfer case, push and hold the transfer case N (Neutral)
button. Some models have a small,
recessed "N" button (at the center of the
transfer case switches) that must be
pressed using a ballpoint pen or similar
object. Other models have a rectangular
N (Neutral) switch, below the rotary
transfer case control knob. The N
(Neutral) indicator light will blink while
the shift is in progress. The light will stop blinking (stay on solid) when the shift to N
(Neutral) is complete. After the shift is
completed and the N (Neutral) light stays
on, release the N (Neutral) button.
5. Release the parking brake.
6. Shift the transmission into REVERSE.
7. Release the brake pedal for five seconds and ensure that there is no vehicle move-
ment.
8. Repeat steps six and seven with automatic transmission in DRIVE.
9. Shift the transmission to NEUTRAL. Firmly apply the parking brake. Turn off the engine.
For vehicles with Keyless Enter-N-Go, push
and hold the ENGINE START/STOP button
until the engine shuts off.
10. Shift the transmission into PARK.
11. Place the ignition in the OFF mode, and remove the key fob.
12. Attach the vehicle to the tow vehicle using a suitable tow bar.
13. Release the parking brake.
Do not disconnect the rear driveshaft
because fluid will leak from the transfer
case, causing damage to internal parts.
Do not use a bumper-mounted clamp-on
tow bar on your vehicle. The bumper face
bar will be damaged.
WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the NEUTRAL (N) position without first
fully engaging the parking brake. The transfer
case NEUTRAL (N) position disengages both
the front and rear driveshafts from the
powertrain, and will allow the vehicle to roll,
even if the automatic transmission is in PARK
(or manual transmission is in gear). The
parking brake should always be applied when
the driver is not in the vehicle.
CAUTION! (Continued)CAUTION!
It is necessary to follow these steps to be
certain that the transfer case is fully in
NEUTRAL (N) before recreational towing to
prevent damage to internal parts.
