pg. 7 Warning lights
The warning lights described on this page should never be on
when driving
When the ignition key is turned on, and before the engine starts, all of the warning lights should be on to
test the function of the bulbs. Should a light not go off after the engine has started, the system indicated
should be inspected. (However, the parking brake reminder light will not go off until the parking brake
is fully released.)

Air conditioning
How to use the air conditioner:
1 FAN
Position 3 for rapid cooling.
The A/C does not operate unless FAN is on.
2 AIR COND
Start the air conditioning compressor by turning the control knob clockwise toward MAX. For rapid
cooling, position the knob into the yellow range beyond MAX. After desired temperature is reached reposition the control knob into the blue range.
At cruising speeds, the knob should be kept within the blue range. If it remains in the yellow range,
icing may occur resulting in decreased cooling capacity.
3 REC (Recirculation)
Push in for rapid cooling and during high humidity conditions.
4 TEMP
When using the air conditioner for cooling, the TEMP control should be set to COOL position, fully left.
Use the AIR COND control to regulate the temperature.
To obtain rapid cooling, all windows must be closed and buttons FLOOR and DEF out. Close the floor
fresh air louver.
Cool air will then be discharged through the four dash outlets which should be fully open.
Note: For rapid removal of condensation from inside glass surfaces, the air conditioner can be switched
