1-3 - Air control levers
With these levers, you can smoothly adjust the flow of warm (or chilled) air.
The extreme left position of the lever - the air supply is blocked. The extreme right position of the lever - the air flow is completely open.
1 - Lever-regulator for air supply to the upper part of the cabin
heated (cooled) air enters through the air supply nozzles to the windshield and front side windows.
2 - Lever-regulator for air supply to the middle part of the cabin
Outside air enters through the guide and metering grilles in the middle of the dashboard and in the front doors, as well as through the metering grille on the top side of the dashboard.
3 - Lever-regulator for air supply to the lower part of the passenger compartment
Air enters through nozzles in the lower part of the cabin, front and rear.
Air supply to the rear seat*
The rear of the passenger compartment is ventilated or cooled through the guide and metering grids in the rear of the center console, regardless of the position of the control levers.
Only outdoor or cooled air can be supplied through these grilles (with the air conditioner on).
4, 6 - Rotary temperature controls for left and right sides
The temperature in the cabin is set by turning the knob to the desired position (temperature in degrees Celsius indicated on a dial). The set temperature is quickly reached after starting the engine and usually remains unchanged, as it is maintained by the electronic controller.
To avoid large temperature fluctuations and excessive load on the heating system, turn the knobs gradually.
In both extreme positions of the regulator on the driver's side, there is no automatic temperature control on either the left or right side, and the heater operates at full power. If the electronic temperature sensor fails, also set the regulator to one of the extreme positions.
5 - Fan switch-regulator
Position "0": The fan is off, there is no forced air supply.
Turn switch to the right (with output from a fixed position) turns on low fan speed and minimum air supply.
Turning further to the right slightly increases airflow without significantly increasing fan speed.
When turning the knob from position "2" to the position "4" the fan speed increases.
For the correct operation of the electronic temperature sensor-controller, the fan control must be installed at least in a vertical position ("12 hours").
Your vehicle is equipped with the ability to quickly defrost the windows.
7 - Switches for setting the fast glass heating mode
The maximum effect is achieved only when the engine is warm. The windows fog up due to differences in temperature outside and inside the car or due to high humidity in the cabin (condensation forms). In this case, the condensate can be quickly eliminated only by intensive supply of hot air directly to the glass.
Key for switching on the automatic control of outdoor air pollution (AUC) *
This system automatically controls the level of harmful substances in the outside air and, if necessary, blocks its entry into the car.
Sequential pressing of the key allows you to select three operating modes:
- Pilot lamps do not light up: outside air enters
- The left control lamp is on: the system's sensors have registered an increased concentration of harmful substances in the outdoor air. If pollution increases, the air supply to the passenger compartment is automatically shut off and only the air in the passenger compartment will be used (recirculation mode).
- The right control lamp is on: the air recirculation mode is on.
Air recirculation button
This mode is recommended for heavily polluted outside air - the air in the cabin circulates and prevents the penetration of outside air.
The control lamp in the pressed key indicates the inclusion of the recirculation mode.
Although the air conditioner automatically turns on the dehumidification mode to improve the air quality, it is not recommended to operate the recirculation mode for a long time.
Note: If the windows begin to mist up when the recirculation mode is switched on, switch this mode off (or AUC) and turn on the air conditioner by pressing button 9.
Air conditioner switch
When the button is pressed, the air conditioner turns on, starting from a temperature of +1°C. The control lamp signals the inclusion of the air conditioner.
The air is cooled and dried.
In some cases, when the air humidity is high, it is recommended to periodically turn on the air conditioner so that excess moisture condenses on the evaporator, and the air in the passenger compartment is thus dried.
At maximum cooling capacity, the system automatically switches to air recirculation mode (with little outside air).
Heated rear window button
Heater operation is described on page 30.
Temperature distribution in the cabin for comfortable conditions: "warm feet - cold head". Adjustment of the air flow through the grilles on the dashboard and in the front doors is carried out by turning the knurled roller 1 (but not at maximum cooling capacity).
- Up: warmer.
- Down: colder.
Important instructions for using the air conditioner
1. The condensate formed in the evaporator is discharged under the bottom of the car and, depending on the humidity of the air, can be up to 2 liters per hour.
2. The air conditioner should be turned on at least for a short time at least once a month (especially during the cold season), otherwise there is a risk of the compressor shaft seals drying out and the refrigerant evaporating as a result.
3. In the event of a malfunction - for example, if there is no cooling even after turning on the air conditioner at maximum power (driver's side temperature control is set to the leftmost position) - turn off the air conditioner and contact BMW Service.
