86
The rear differential lock system is
provided for use only when wheel
spinning occurs in a ditch or on a slip-
pery or ragged surface.
This differential lock system is effective in case one of the rear wheels is spinning.
Before using the rear differential lock sys-
tem, first shift the front drive control into L4º with the free-wheeling hubs engaged
to see if it works. If this has no ef fect, addi-
tionally use the rear differential lock sys-tem.
Do not use the rear differential lock
in the conditions other than above.
Large steering effort and careful
cornering control will be required. CAUTION
!
To lock the rear differential, push the switch.
Be sure to stop the wheels before locking
the differential.
Vehicles with manual transmissionÐFor
easy locking, depress the clutch pedal,
push the lock switch and slowly release the clutch pedal.
The indicator light will blink when the
switch is
turned on. Wait a few seconds for
the system to complete operation. After
the differential is locked, the light will stop
blinking and remain on.

The anti-lock brake system does not op-
erate when the rear differential is locked.
It is normal operation for the ABSº warn-
ing light to be on at this time.

Do not lock the differential until
the wheels have stopped spin-
ning. Otherwise, the vehicle may
move in an unexpected direction
when the differential lock is en-
gaged, resulting in an accident.
This may also lead to possible
damage to differential lock com-
ponent parts.
Do not drive over 8 km/h (5 mph)
when the differential is locked. CAUTION
!
To unlock the differential, push the
switch once again.
Unlock the differential as soon as the ve- hicle moves out.
For easy unlocking, slightly turn the steer-
ing wheel in either direction while the ve- hicle is in motion.
When the differential lock is disengaged, the indicator light will go out. The differential will also unlock if you shift
the front drive control lever out of L4º. Never f
orget to turn off the switch after us-
ing this feature.
To check the indicator bulb, turn the igni-
tion key to the ONº position, but do not
start the engine.
Do not keep driving with the
differential lock switch on. CAUTION
!
When parking, firmly apply the park-
ing brake to avoid inadvertent creep- ing.
To set: Pull up the lever. For better holding
power, first depress the brake pedal and

ILLUMINATION CONTROL LOGIC
On some audio-units, when the instru-
ment panel lights are on, the letters on op-
erable buttons of the mode in current use
light up together with the mode selectionand eject buttons. RADIO RECEPTION
Usually, a problem with radio reception
does not mean there is a problem with
your radioÐit is just the normal result of
conditions outside the vehicle.
For example, nearby buildings and terrain
can interfere with FM reception. Power
lines or telephone wires can interfere with
AM signals. And of course, radio signals
have a limited range, and the farther you are from a station, the weaker its signal
will be. In addition, reception conditions
change constantly as your vehicle moves. Here are some common reception prob-lems
that probably do not indicate a prob-
lem with your radio: FM
Fading and driving stationsÐGenerally,
the effective range of FM is about 40 km
(25 miles). Once outside this range, you
may notice fading and drifting, which in- crease with the distance from the radio
transmitter. They are often accompanied by distortion.
Multi-pathÐFM signals are reflective,
making it possible for two signals to reach
your antenna at the same time. If this hap-
pens, the signals will cancel each other
out, causing a momentary flutter or loss of
reception.
Static and flutteringÐThese occur when
signals are blocked by buildings, trees, or other large objects. Increasing the bass
level may reduce static and fluttering.
Station swappingÐIf the FM signal you are listening to is interrupted or weak-
ened, and there is another strong station
nearby on the FM band, your radio may
tune in the second station until the original
signal can be picked up again. AM FadingÐAM broadcasts are reflected by the upper atmosphere-especially atnight. These reflected signals can inter-
fere with those received directly from the radio station, causing the radio station tosound alternately strong and weak.
Station interferenceÐWhen a reflected
signal and a signal received directly from a radio station are very nearly the same
frequency, they can interfere with each
other,
making it difficult to hear the broad-
cast.
StaticÐAM is easily affected by external sources of electrical noise, such as high
tension power lines, lightening, or electri-cal motors. This results in static.
CARING FOR YOUR CASSETTE PLAY-
ER AND TAPES
For high performance from your cassette
player and tapes:
Clean the tape head and other parts regu-
larly. A dirty tape head or tape path can de-
crease sound quality and tangle your
cassette tapes. The easiest way to
clean them is by using a cleaning tape.
(A wet type is recommended.)
