vehicle is in gear and/or moving, the Four-Wheel Low
indicator light will ash for 30 seconds and not complete
the shift unless the vehicle is moving less than 2 mph
(3.2 km/h) and the transmission is in N (Neutral).
After 30 seconds, the transfer case will return to the
setting last chosen.
Shifting Out of Four-Wheel Low
To shift from Four-Wheel Low to Four-Wheel High, Auto
Four-Wheel Drive, or Two-Wheel High, the vehicle must
be stopped or moving less than 2 mph (3.2 km/h) with the
transmission in N (Neutral) and the engine running. The
preferred method for shifting out of Four-Wheel Low is to
have your vehicle moving 1 or 2 mph (1.6 to 3.2 km/h).
Turn the knob to Four-Wheel High, Auto Four-Wheel
Drive, or Two-Wheel High. You must wait for the
Four-Wheel High, Auto Four-Wheel Drive, or Two-Wheel

to R (Reverse) for one second, then shift the
transmission to D (Drive) for one second, to

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.
With four-wheel drive, the vehicle will be free to
roll — even if the shift lever is in P (Park) — if your
transfer case is in Neutral. So, be sure the transfer
case is in a drive gear — not in Neutral. See
Four-Wheel Drive on page 2-30. Always put the
shift lever fully in P (Park) with the parking brake
rmly set. If you are pulling a trailer, seeTowing a
Trailer on page 4-48.To shift into P (Park):
1. Hold the brake pedal down with your foot and set
the parking brake.
2. Move the shift lever into P (Park) by pressing the
button on the side of the shift lever and pushing
the lever all the way toward the front of the vehicle.
3. Turn the ignition key to OFF/LOCK.
4. Remove the key and take it with you. You know the
vehicle is in P (Park) if the key can be removed
from the ignition.

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.
If you have four-wheel drive, the vehicle will be
free to roll – even if your lever is in P (Park) – if
the transfer case is in Neutral. So be sure the
transfer case is in a drive gear – not Neutral.
SeeFour-Wheel Drive on page 2-30.
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 unless you have to.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).
Torque Lock
If you are parking on a hill and you do not shift your
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 2-35.
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).

Engine Exhaust
{CAUTION:
Engine exhaust contains Carbon Monoxide (CO)
which cannot be seen or smelled. Exposure to CO
can cause unconsciousness and even death.
Exhaust may enter the vehicle if:
The vehicle idles in areas with poor ventilation
(parking garages, tunnels, deep snow that
may block underbody airow or tail pipes).
The exhaust smells or sounds strange or
different.
The exhaust system leaks due to corrosion or
damage.
CAUTION: (Continued)
CAUTION: (Continued)

The vehicle’s exhaust system has been
modied, damaged or improperly repaired.
There are holes or openings in the vehicle
body from damage or after-market
modications that are not completely sealed.
If unusual fumes are detected or if it is suspected
that exhaust is coming into the vehicle:
Drive it only with the windows
completely down.
Have the vehicle repaired immediately.
Never park the vehicle with the engine running in
an enclosed area such as a garage or a building
that has no fresh air ventilation.

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 2-38.
{CAUTION:
It can be dangerous to get out of the vehicle if the
automatic transmission shift lever is not fully in
P (Park) with the parking brake rmly set.
CAUTION: (Continued)
CAUTION: (Continued)
Thevehicle can roll. Do not leave the vehicle when
the engine is running unless you have to. 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, always set the parking
brake and move the shift lever to P (Park).
{CAUTION:
If the vehicle has four-wheel drive, it will be free to
roll — even if the shift lever is in P (Park) — if the
transfer case is in N (Neutral). So be sure the
transfer case is in a drive gear — not in N (Neutral).
SeeFour-Wheel Drive on page 2-30.
Follow the proper steps to be sure the vehicle will not
move. SeeShifting Into Park on page 2-35.
