Manual Air Conditioning

87 - Air Conditioning, Manual Air Conditioning

Functions

This air conditioning system, which enables continuous adjustment and setting of the desired cooling power and air flow rate (fan speed) via rocker switches according to individual wishes, controls the temperature of the conditioned air mixture by mixing warm and cold air in the heater box.

Operation (operation of the manual air conditioning system)

The air conditioning system is operated by way of a control panel (a/c controls) with integrated control unit in the center console. The appearance of the control panel for the manual air conditioning system is based on that of the control panel for the automatic climate control system.

The key features of the control panel are:
- Integration of the interior temperature sensor (required for the seat heating functions)
- Integration of the switches for heating the driver's and passenger's seats (previously in the center console)
- Integration of the button for heating the rear window (previously located beside the operating unit)
- Introduction of switches for adjusting the temperature and fan power (higher setting = switch up, lower setting = switch down)
- "ECO" marking (ECOnomy mode) on the button for switching the air conditioning compressor on and off (snowflake symbol on display goes on/off accordingly).

As a result of these changes, all of the heating functions in the vehicle are now together in a single unit.

The following items of information can be called up on the air conditioning display:
- Temperature and air flow rate (fan speed)
- A/C compressor on/off
- AC max mode
- Air distribution

The temperature is presented on the display by way of a bar display. When no bar is visible, the temperature is set to the maximum cold setting (low) When all the bars are visible, the temperature is set to the maximum warm setting (high)

Control Panel (Manual A/C)







E - ECO Button (air-conditioning compressor off/on)

The ECO button enables the selection of ECOnomy mode, which functions without the a/c compressor. ECOnomy mode permits cooling to values down to the exterior temperature.

H - AC Max Mode

This button can be pressed in any other operating mode to cool the vehicle's interior as quickly as possible.

- The temperature display indicates the lowest value and the fan is activated at maximum speed
- Distribution flap for fresh air/recirculated air is closed
- Air flow is directed to the defrost air outlet vents (front windshield) and the central and side vents

Other button functions on the control panel are explained in the section on "Automatic climate control".
