Electrical Disturbances
Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.
AM Reception
AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.
FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.
NOTE:The radio, steering wheel radio controls (if
equipped), and 6 disc CD/DVD changer (if equipped)
will remain active for up to 10 minutes after the ignition
switch has been turned off. Opening a vehicle front door
will cancel this feature.

REMOTE SOUND SYSTEM CONTROLS — IF
EQUIPPED
The remote sound system controls are located on the rear
surface of the steering wheel. Reach behind the wheel to
access the switches.The right hand control is a rocker type switch with a push
button in the center. Pressing the top of the switch will
increase the volume and pressing the bottom of the
switch will decrease the volume.
The button located in the center of the right hand control
will switch modes to Radio or CD.
The left hand control is a rocker type switch with a push
button in the center. The function of the left hand control
is different depending on which mode you are in.
The following describes the left hand control operation in
each mode.
Radio Operation
Pressing the top of the switch will SEEK up for the next
listenable station and pressing the bottom of the switch
will SEEK down for the next listenable station.

FOUR-WHEEL DRIVE OPERATION
NV233/243 GII Transfer Case Operating
Information/Precautions
The NV233/243 is an electric shift transfer case and is
operated by the 4WD Control Switch (Transfer Case
Switch), which is located on the instrument panel.
The NV233/243 transfer case provides 4 mode positions:
2 (rear) wheel drive high range, 4 wheel drive high range,
4 wheel drive low range, and neutral.
The NV233/243 transfer case is designed to be driven in
the 2 wheel drive position (2WD) for normal street and
highway conditions (dry hard surfaced roads).
When additional traction is required, the transfer case
4WD LOCK and 4WD LOW positions 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 thedesired position - see Shifting Procedure section for
specific shifting instructions. The 4WD LOCK and 4WD
LOW positions are designed for loose or slippery road
surfaces only. Driving in the 4WD LOCK and 4WD LOW
positions on dry hard-surfaced roads may cause in-
creased tire wear and damage to the driveline compo-
nents.
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 is no indicator light on or
flashing, the transfer case position is two-wheel drive
STARTING AND OPERATING 199

(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 casewill 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 control knob back to the current position, wait five (5)
seconds, and retry selection. To find the shift require-
ments, refer to theShifting Procedurefor your transfer
case, located in this section of the owner’s manual.
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 theSVC 4WDlight is illumi-
nated. 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
200 STARTING AND OPERATING
Page 201 of 400

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 4 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 4 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:

NOTE:If any of the requirements to select a new
transfer case position have not been met, the transfer case
will not shift, the indicator light for the previous position
will remain ON, and the newly selected position indica-

for the selected position have been met. To retry a shift:
