PRECAUTION
1. DO NOT HANDLE REFRIGERANT IN AN ENCLOSED
AREA OR NEAR AN OPEN FLAME
2. ALWAYS WEAR EYE PROTECTION
3. BE CAREFUL NOT TO GET LIQUID REFRIGERANT IN
YOUR EYES OR ON YOUR SKIN
If liquid refrigerant gets in your eyes or on your skin.
(a) Wash the area with lots of cool water.
CAUTION:
Do not rub your eyes or skin.
(b) Apply clean petroleum jelly to the skin.
(c) Go immediately to a physician or hospital for professional
treatment.
4. NEVER HEAT CONTAINER OR EXPOSE IT TO OPEN
FLAME
5. BE CAREFUL NOT TO DROP CONTAINER OR NOT TO
APPLY PHYSICAL SHOCKS TO IT
6. DO NOT OPERATE COMPRESSOR WITHOUT
ENOUGH REFRIGERANT IN REFRIGERATION SYS-
TEM
If there is not enough refrigerant in the refrigerant system, oil lu-
brication will be insufficient and compressor burnout may occur.
Necessary care should be taken to avoid this.
7. DO NOT OPEN PRESSURE MANIFOLD VALVE WHILE
COMPRESSOR IS OPERATING
If the high pressure valve is opened, refrigerant flows in the re-
verse direction and could cause the charging cylinder to rup-
ture, so open and close only the low pressure valve.
8. BE CAREFUL NOT TO OVERCHARGE SYSTEM WITH
REFRIGERANT
If refrigerant is overcharged, it causes problems such as insuffi-
cient cooling, poor fuel economy, engine overheating, etc.

senger 's seat).
At this time, the indicator light will illumi-
nate to indicate the seat heater is operat-
ing.
The seat heater switches have the follow-
ing positions.
ªHIºÐHigh heating temperature
ªLOºÐLow heating temperature
The key must be in the ªONº position to
operate seat heaters.
Pushing lightly on the opposite side will
turn it off.
CAUTION
Occupants must use caution when op-
erating the seat heater because it
may make them feel too hot or cause
burns at low temperatures (erythema,
varicella). Use extra caution for;

Babies, small children, elderly per-
sons, sick persons or persons with
physical disabilities

Persons who have delicate skin

Persons who are exhausted

Person who have taken alcohol or
drugs which induce sleep (sleeping
drug, cold remedy, etc.)
To prevent the seat overheating, do
not use the seat heater with a blan-
ket, cushion, or other insulating ob-
jects which cover the seat.
NOTICE

Do not put unevenly weighed ob-
jects on the seat and do not stick
sharp objects (needles, nails, etc.)
into the seat.

When cleaning the seats, do not
use organic substances (paint thin-
ner, benzine, alcohol, gasoline,
etc.). They may damage the heater
and seat surface.

tions
The ª3º, ª2º and ªLº positions are used for
strong engine braking as described pre-
viously.
With the selector lever in ª3º, ª2º or
ªSHIFT Lº switch depressed, the vehicle
can start just as if the lever was in ªDº.
With the selector lever in ª3º or ª2º, the
vehicle will start in first gear and automat-
ically shift to second gear.
With the ªSHIFT Lº switch depressed, the
transmission is engaged in first gear.NOTICE

Be careful not to over±rev the en-
gine. Watch the tachometer to keep
engine rpm from going into the red
zone. The approximate maximum al-
lowable speed for each position is
given above for your reference:
Two±wheel drive models
ª3º 135 km/h (84 mph). . . . . . .

Do not continue hill climbing or
hard towing for a long time in the
ª3º, ª2º or ªLº position. This may
cause severe automatic transmis-
sion damage from overheating. To
prevent such damage, ªDº position
should be used in hill climbing or
hard towing.
(g) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with
your foot, shift the selector lever to the

2. Bi±levelÐAir flows from both the floor
vents and the instrument panel vents.
When you set the temperature selector
setting at about the middle in automatic
operation, warm air flows out of the
floor vents and relatively low±tempera-
ture air flows out of the center and
side vents.
3. FloorÐAir flows mainly from the floor
vents.
It is recommended that you close the
lower vent. For details about this, see
ªInstrument panel ventsº on page 297
in this Section.
4. Floor/WindshieldÐAir flows mainly
from the floor vents and windshield
vents and fan speed may increase in
order to clean up the front view.
This position allows the air intake to
select FRESH automatically. This is to
clean up the front view more quickly.
If you want to return the setting to
RECIRCULATE mode, press the air in-
take selector button once again.
It is recommended that you close the
lower vent. For details about this, see
ªInstrument panel ventsº on page 297
in this Section.For details about air flow selector settings,
see ªÐAir flow selector settingsº de-
scribed below.
Windshield air flow button
When this button is pressed, air flows
mainly from the windshield vents and fan
speed may increase in order to clean up
the front view.
Pressing the button once again returns the
air flow mode to the last one used.
When this button is pressed, air intake
selector mode changes to FRESH auto-
matically to clean up the front view quick-
ly. It is not possible to return to RECIR-
CULATE in this mode.
Press the ªA/Cº button for dehumidified
heating or cooling. This setting clears the
front view more quickly.
