Brake/Transmission Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in the
PARK position when the ignition switch is in the LOCK
position. To move the shift lever out of the PARK
position, the ignition switch must be turned to any other
switch position (ACC, ON, or START) (engine running or
not) and the brake pedal must be pressed.
Automatic Transmission
The electronic PRNDL on the instrument cluster indicates
the transmission gear selected. The shift lever is mounted
on the right side of the steering column. To drive, move
the shift lever from PARK or NEUTRAL to the desired
drive position. Pull the shift lever toward you when
shifting into REVERSE, SECOND, FIRST or PARK, or
when shifting out of PARK.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL position into another gear range.
PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never use PARK while the vehicle is in motion. Apply
the parking brake when leaving the vehicle in this range.
Always apply the parking brake first, then place the shift
lever into the PARK position.
WARNING!
•Never use the PARK position as a substitute for
the parking brake. Always apply the parking
brake fully, when parked, to guard against vehicle
movement and possible injury or damage.(Continued)

WARNING! (Continued)
•It is dangerous to move the shift lever out of PARK
or NEUTRAL 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 reverse. 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.
REVERSE
This range is for moving the vehicle backward. Use only
after the vehicle has come to a complete stop.
NEUTRAL
This range is used when vehicle is standing for pro-
longed periods with engine running. Engine may be
started in this range. Set the parking brake if you must
leave the vehicle.
DRIVE
This range is for most city and highway driving.
2 (Second)
This range is for driving slowly in heavy city traffic or on
mountain roads where more precise speed control is
desirable, use second gear. Use it also when climbing
long grades, and for engine braking when descending
moderately steep grades. To prevent excessive engine
speed, do not exceed 45 mph (72 km/h) in this range.
1 (First)
This range is for driving up very steep hills and for
engine braking at low speeds, 25 mph (40 km/h) or less,
when going down hill, use first gear. To prevent excessive
engine speed do not exceed 25 mph (40 km/h) in this
range.
Overdrive Operation
The Overdrive automatic transmission contains an
electronically-controlled fourth and fifth (if equipped)
254 STARTING AND OPERATING
Page 256 of 450

gear (Overdrive). The transmission will automatically
shift from Drive to Overdrive, if the following conditions
are present:
•the shift lever is in DRIVE;
•the engine coolant has reached normal operating tem-
perature;
•vehicle speed is above approximately 30 mph
(48 km/h);
•the TOW/HAUL switch has not been activated;
•transmission has reached normal operating
temperature.
NOTE:
•If the vehicle is started in extremely cold temperatures,
the transmission may not shift into Overdrive and will automatically select the most desirable gear for opera-
tion at this temperature. Normal operation will re-
sume when the transmission fluid temperature has
risen to a suitable level. Refer to “Torque Converter
Clutch” in this section.
•If the transmission temperature gets extremely hot, the
transmission will automatically select the most desir-
able gear for operation at this temperature. If the
transmission temperature becomes hot enough, the
“Transmission Temperature Warning Light” may illu-
minate and the transmission may downshift out of
Overdrive until the transmission cools down. After
cool down, the transmission will resume normal
operation.
The transmission will downshift from Overdrive to
DRIVE if the accelerator pedal is fully pressed at vehicle
speeds above approximately 35 mph (56 km/h).

positions are designed for loose or slippery road surfaces
only. Driving in the 4WD LOCK and 4WD LOW posi-
tions on dry hard-surfaced roads may cause increased
tire wear and damage to the driveline components.
NOTE:The transfer case NEUTRAL position is selected
by pressing the recessed button located on the lower
left-hand corner of the transfer case switch. The transfer
case NEUTRAL position is to be used for recreational
towing only. Refer to “Recreational Towing” in “Starting
and Operating” for further information.
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD and
4LOW) are located on the instrument cluster. If there is
no indicator light on or flashing, the transfer case is in
two-wheel drive (2WD). If the indicator light is on, the
desired position (4WD LOCK and 4WD LOW) has been
obtained. If one or more shift requirements are not met:
1. An indicator light will flash.
2. The transfer case
will notshift.
NOTE: Before retrying a selection, make certain that all
the necessary requirements for selecting a new transfer
case position have been met. To retry the selection, turn
the transfer case switch back to the current position, wait
five seconds, and retry selection. To find the shift require-
ments, refer to the Shifting Procedurefor further
information.
The “SVC 4WD Warning Light” monitors the electronic
shift four-wheel drive system. If this light remains on
after engine start-up or illuminates during driving, it
means that the four-wheel drive system is not function-
ing properly and that service is required.

WARNING!
Always engage the parking brake when powering
down the vehicle if the “SVC 4WD Warning Light” 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 NV233/243 trans-
fer case is not equipped with a synchronizer and there-
fore 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 trans-
fer case. When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 2WD or
4WD LOCK positions at a given road speed. Take care
not to overspeed the engine and do not exceed 25 mph
(40 km/h).
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 position without first fully engaging the
parking brake. The transfer case NEUTRAL 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, refer to the following infor-
mation:
2WD
Rear-Wheel Drive High — This range is used for normal
street and highway driving on dry, hard-surfaced roads. 4WD LOCK
Four-Wheel Drive Lock — This range locks the front and
rear driveshafts together forcing the front and rear wheels
to rotate at the same speed. This range provides addi-
tional traction for loose or slippery road surfaces only.
4WD LOW
Four-Wheel Drive Low — This range provides low speed
four-wheel drive. It locks the front and rear driveshafts
together, forcing the front and rear wheels to rotate at the
same speed. This range provides additional traction and
maximum pulling power for loose or slippery road
surfaces only. Do not exceed 25 mph (40 km/h).
N
Neutral — This range disengages both the front and rear
driveshafts from the powertrain, and is used for flat
towing behind another vehicle. Refer to “Recreational
Towing” in “Starting and Operating” for further
information.

LIMITED-SLIP REAR AXLE DIFFERENTIAL — IF
EQUIPPED
The limited-slip differential provides additional traction
on snow, ice, mud, sand and gravel. It improves traction
when there is a difference between the characteristics of
the surface under the right and left rear wheels. During
normal driving and cornering, the limited-slip unit is
similar to a conventional differential. But on a slippery
surface, the differential delivers more of the driving effort
to the wheel having the better traction.
WARNING!
On vehicles equipped with a limited-slip differen-
tial, never run the engine with one rear wheel off the
ground. The vehicle may drive through the rear
wheel remaining on the ground and cause you to lose
control of the vehicle.Care should be taken to avoid sudden accelerations when
both rear wheels are on a slippery surface. This could
cause both rear wheels to spin, and allow the vehicle to
slide sideways on the crowned surface of a road or in a
turn.
DRIVING ON SLIPPERY SURFACES
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precau-
tions should be observed:
1. Slow down during rainstorms or when roads are
slushy.
2. Slow down if the road has standing water or puddles.
264 STARTING AND OPERATING
Page 266 of 450

3. Replace tires when tread wear indicators first become
visible.
4. Keep tires properly inflated.
5. Maintain sufficient distance between your vehicle and
the car in front of you to avoid a collision in a sudden
stop.
DRIVING THROUGH WATER
Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle.
Flowing/Rising Water
WARNING!
Do not drive on or across a road or path where water
is flowing and/or rising (as in storm run-off). Flow-
ing water can wear away the road or path’s surface
and cause your vehicle to sink into deeper water.
Furthermore, flowing and/or rising water can carry
your vehicle away swiftly. Failure to follow this
warning may result in injuries that are serious or
fatal to you, your passengers, and others around you.
Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following Caution
and Warning before doing so.
