Ventilation, heating and air conditioning system (Mitsubishi L200 4)

Air flow distribution diagram in the car interior

The car is equipped with a ventilation and heating system.

Air conditioning is installed as an option. The air conditioning can be manual or automatic.

The ventilation, heating and air conditioning system is a single functional complex designed to provide a comfortable microclimate in the car, regardless of weather conditions and outside air temperature. The heater and electric heater provide an increase in temperature, the air conditioning system unit provides a decrease in temperature and humidity in the cabin.

The heater or air conditioner can only be turned on when the engine is running.

Note: The instrument panel contains a light sensor (A) and a cabin temperature sensor (B), which are part of the ventilation and air conditioning system. Do not place any objects on them - this will cause the system to malfunction.

Direction of air flow depending on the position of the air supply mode selection regulator

The direction of the air flow and the intensity of air supply to different areas of the cabin are changed by the mode selection switch.

Air supply to the upper zone of the cabin

Air flows are directed only to the upper zone of the cabin.

Air supply to the upper and lower parts of the cabin

Air flows are directed to the upper zone of the cabin and the lower zone (to the feet of the driver and passengers).

Air supply to the lower part of the cabin

Most of the air flow is directed to the lower area (towards the feet).

Note: If the switch is between positions и , most of the air enters the upper part of the cabin.

If the switch is between positions и , most of the air goes to the feet.

Supply of air to the lower part of the passenger compartment and heating of the windows

Air is supplied to the feet, windshield and front door windows.

Glass heating

Most of the air flow is directed to the windshield and front door windows.

Note: If the switch is between positions и , most of the air goes to the feet. If the switch is between positions и , most of the air goes to the windshield and front door windows.

Air conditioner operating rules

Try to park your car in the shade. When parked in the sun, the car interior heats up very much and will take longer to cool down. If you do have to leave your car in the sun, open the windows for a few minutes after turning on the air conditioner to let the hot air out of the car.

Close the windows when the air conditioner is running. The flow of outside air through open windows reduces the efficiency of the air conditioner's cooling effect.

Too much cooling is harmful to health. The air temperature in the cabin should be only 5-6°C lower than the outside air temperature.

When turning on the air conditioner, make sure that the air intake located in front of the windshield is not blocked by anything (such as leaves). Leaves accumulated at the entrance to the air intake can reduce the air supply and block the condensation drain holes.

Recommendations for choosing refrigerant and lubricants for air conditioners

A possible cause of decreased air conditioning efficiency is a refrigerant leak. It is recommended to have the system checked by an authorized MITSUBISHI MOTORS service center. The vehicle's air conditioning system must be filled with HFC-134 refrigerant and ZXL-1OOPG lubricant. Using any other refrigerant or lubricant may cause serious damage, requiring replacement of the entire air conditioning system. It is not recommended to release refrigerant into the atmosphere.

It is recommended to return the refrigerant for recycling and reuse.

If the air conditioner is not used for a long time

It is necessary to turn on the air conditioner for at least five minutes a week, even in cold weather. This is done to lubricate the compressor parts and keep the system in working order. If the air conditioner is not turned on for a long time, a foreign smell may appear when it is turned on. This is not a sign of a malfunction of the system.
