WARNING!
Your vehicle could move and injure you and others if
it is not completely in P (Park). Check by trying to
move the gearshift lever back and forth without first
pulling the lever toward you, after you have set it in
P (Park). Make sure it is in Park before leaving the
vehicle.
WARNING!
Never use Park position on an automatic transmis-
sion as a substitute for the parking brake. Always
apply parking brake fully when parked to guard
against vehicle movement and possible injury or
damage.
WARNING!
It is dangerous to shift the selector lever out of “P” or
“N” if the engine speed is higher than idle speed. If
your foot is not firmly on the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and when your right
foot is firmly on the brake pedal.
“R” Reverse
Use this range only after the vehicle has come to a
complete stop.

the fluid partially draining from the torque converter into
the transmission. This condition is normal and will not
cause damage to the transmission. The torque converter
will refill within five seconds of shifting from Park into
any other gear position.
FOUR-WHEEL DRIVE OPERATION
NV 144 Transfer Case Operating
Information/Precautions
The NV 144 is an electric shift transfer case and is
operated by the Four-Wheel-Drive (4WD) Control
Switch, which is located on the instrument panel.
The NV 144 transfer case provides 2 mode positions:
All-Wheel Drive (AWD) and 4-Wheel-Drive LOCK.
The NV 144 transfer case is designed to be driven in for
AWD for normal street and highway conditions (all road
surfaces roads).When additional traction is required, the transfer case
4LOCK position can be used to lock the front and rear
driveshafts together and force the front and rear wheels
to rotate at the same speed. This is accomplished by
rotating the 4WD Control Switch to the 4LOCK position
- see Shifting Procedure section for specific shifting
instructions. The 4LOCK position is designed for loose,
slippery road surfaces only. Driving in the 4LOCK posi-
tion on dry hard surfaced roads may cause increased tire
wear and damage to the driveline components.
Transfer Case Position Indicator Lights
Transfer case position indicator lights are located on the
instrument cluster, and indicate the current and desired
transfer case selection. If there are no indicator lights on
or flashing the transfer case position is All-Wheel Drive
(AWD).
The “SVC 4WD” warning light monitors the electric shift
4WD system. If this light remains on after engine start up
226 STARTING AND OPERATING
Page 227 of 416

or illuminates during driving, it means that the 4WD
system is not functioning properly and that service is
required.
WARNING!
Always engage the parking brake when powering
down the vehicle if theService 4WDlight is
illuminated. Not engaging the parking brake may
allow the vehicle to roll which may cause personal
injury.
NOTE:Do not attempt to make a shift while only the
front or rear wheels are spinning. The NV 144 transfer
case is not equipped with a synchronizer and therefore
the front and rear driveshaft speeds must be equal for the
shift to take place. Shifting while only the front or rear
wheels are spinning can cause damage to the transfer
case.Proper operation of four-wheel-drive vehicles depends
on tires of equal size, type and circumference on each
wheel. Any difference in tire size can cause damage to the
transfer case.
Because four-wheel-drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
For additional information on the appropriate use of each
transfer case mode position see the information below:
AW D
Normal All-Wheel-Drive High Range - Employs inter-
axle differential. Allows front and rear wheels to rotate at
different speeds. All road surfaces.

vehicle in the 4LOCK position on dry hard surfaced
roads. This feature provides the safety, security, and
convenience of operating in all-wheel drive at all times
regardless of road conditions.
When additional traction is required, the 4LOCK and
4LO positions can be used to lock the front and rear
driveshafts together through the transfer case inter-axle
differential and force the front and rear wheels to rotate
at the same speed. This is accomplished by rotating the
4WD Control Switch to these positions. The 4LOCK and
4LO positions are intended for loose, slippery road
surfaces only. Driving in the 4LOCK and 4LO positions
on dry hard surfaced roads may cause increased tire wear
and damage to the driveline components.
The transfer case Neutral (N) position is selected by
depressing the recessed button located on the lower left
hand corner of the 4WD Control Switch.NOTE:The transfer case Neutral (N) position is to be
used for recreational towing only. See Recreational Tow-
ing section for specific procedures on shifting into and
out of Neutral (N).
Transfer Case Position Indicator Lights
Transfer case position indicator lights are located on the
instrument cluster. If there are no indicator lights on or
flashing the transfer case position is All-Wheel Drive
(AWD) and indicate the current and desired transfer case
selection (4HI⇔4LOCK).
The “SVC 4WD” warning light monitors the electric shift
4WD system. If this light remains on after engine start up
or illuminates during driving, it means that the 4WD
system is not functioning properly and that service is
required.

WARNING!
Always engage the parking brake when powering
down the vehicle if theService 4WDlight is
illuminated. Not engaging the parking brake may
allow the vehicle to roll which may cause personal
injury.
NOTE:Do not attempt to make a shift while only the
front or rear wheels are spinning. The NV 244 Generation
II transfer case is not equipped with a synchronizer and
therefore the front and rear driveshaft speeds must be
equal for the shift to take place. Shifting while only the
front or rear wheels are spinning can cause damage to the
transfer case.
When operating your vehicle in 4LO, the engine speed is
approximately three times that of the AWD or 4LOCKpositions at a given road speed. Take care not to over-
speed the engine and do not exceed 40 km/h (25 mph).
Proper operation of four-wheel-drive vehicles depends
on tires of equal size, type and circumference on each
wheel. Any difference in tire size can cause damage to the
transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.

WARNING!
You or others could be injured 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 move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
For additional information on the appropriate use of each
transfer case mode position see the information below:

Be sure the parking brake is firmly set when parked and
the gear-shift lever is in PARK position. When parking on
a hill you should apply the Parking Brake before placing
the gear shift lever in PARK; otherwise the load on the
transmission locking mechanism may make it difficult to
move the selector out of PARK.NOTE:The instrument cluster brake warning light
indicates only that the parking brake is applied. You must
be sure the parking brake is fully applied before leaving
the vehicle.
When parking on a hill, turn the front wheels toward the
curb on a downhill grade and away from the curb on an
uphill grade.
The parking brake should be applied whenever the
driver is not in the vehicle.

WARNING!
•Always fully apply the parking brake when leav-
ing your vehicle, or vehicle may roll and cause
damage or injury. Also be certain to leave an
automatic transmission in Park. Failure to do so
may cause the vehicle to roll and cause damage or
injury.
•Be sure the parking brake is fully disengaged
before driving, failure to do so can lead to brake
failure and an accident.
•Leaving children in a vehicle unattended is dan-
gerous for a number of reasons. A child or others
could be injured. Children should be warned not
to touch the parking brake or the gear selector
lever. Don’t leave the key in the ignition. A child
could operate power windows, other controls, or
move the vehicle.
BRAKE SYSTEM
In the event power assist is lost for any reason, (for
example, repeated brake applications with the engine
off), the brakes will still function. The effort required to
brake the vehicle will be significantly increased over that
required with the power system operating.
If either the front or rear hydraulic systems lose normal
capability, the remaining system will still function with
some loss of braking effectiveness. This will be evident by
increased pedal travel during application, greater pedal
force required to slow or stop, and activation of the Brake
Warning Lamp and the ABS Lamp during brake use.
Four-Wheel Anti-Lock Brake System (ABS)
This Anti-Lock Brake System is designed to aid the driver
in maintaining vehicle control under adverse braking
conditions. The system operates with a separate com-
puter to modulate hydraulic pressure to prevent wheel
lockup and help avoid skidding on slippery surfaces.
