ECC - Electronic Climate Control


This is an automatic system that also permits manual operation. The in-car temperature is automatically monitored by two sensors located in the passenger compartment.
One sensor is located on the top of the dashboard where it can sense sunlight. The second sensor is located on the courtesy light where it can sense the temperature in the center of the car. The following pages describe how ECC works and how it can be used most effectively.

The air conditioning system is OFF when this button is depressed (the light will be on). The light has two functions:

  • air conditioning OFF*
  • fault in system (see next page)


    * When the function selector is in the mode, the air conditioning system is ON and recirculation is OFF, regardless of button position. The light surrounding the "AC OFF" button will be OFF and the light surrounding the recirculation button will be OFF.

    Automatic setting


    The ECC system will automatically maintain a comfortable in-car temperature regardless of the outdoor temperature.



    Select the desired temperature


    The blower will run at its maximum speed in either the max cooling or max heating positions.
    Water under the vehicle in hot weather can be the result of condensation from the air conditioning system.


    Optimum defrosting



    Set the function dial to .
    The air conditioning light will NOT go on.
    When the windows have cleared, set the blower control to position 2.


    Operating Tips


    When the outside air is contaminated with exhaust gases, smoke etc. (as when driving through a tunnel) or to cool the car quickly, push the recirculation button . In this position, no air is drawn into the passenger compartment from outside. However, do not leave the system in this mode for more than 10-15 minutes, since the air inside the car will become stale and the windows may fog.


    NOTE:

  • Do not place any objects over the sensor in the passenger side speaker grille as this will cause the ECC system to respond incorrectly to ambient conditions.
  • To help maintain stable passenger compartment temperature when driving with the sun roof or windows open, place the blower control in position "0" and adjust the desired temperature manually.
  • The air conditioning compressor only engages at temperatures above 41°F (5°C).
  • Always keep the air intake grille at the base of the windshield free of snow.


  • Volvo cares about the environment. The air conditioning system in your car contains a CFC-free refrigerant - R134a. This substance will not deplete the ozone layer. The system contains 2 lbs. (0.9 kg) R134a and uses Sanden SP-20 (type PAG) oil.


    ECC system fault indication


    If the light in the air conditioning push button begins to flash when the ignition is switched on, a simple fault is indicated. The system will compensate by substituting a standard value stored in the memory. System performance loss will be slight.
    If the light continues to flash more than 20 seconds, a more serious fault is indicated. While the system will again attempt to substitute a standard value, some reduction in system performance will become apparent. Contact your authorized Volvo retailer for service.

    Maximum heating:


    Close the center panel vents. When the passenger compartment has become sufficiently warm, set the blower control to position 2 and adjust the temperature.


    Maximum cooling:


    Open the vents. The button should be depressed. Adjust the temperature with the temperature dial.


    To demist / Defrost the windows


    Set the function dial to position . When the windows have cleared set the blower control to position 2 and the function selector to . Always keep the air intake grille at the base of the windshield free of snow.


    Operating tips
    The air conditioning system functions only at temperatures above 43°F (6°C).
    The air conditioning will only function if the blower is set to position 1 or higher.
    Choose this position if the outside air is contaminated with exhaust gases, smoke, etc or to heat/cool the car quickly. In this position, very little air is drawn into the passenger compartment from the outside. Do not leave the system in this mode for more than 10-15 minutes since the air inside the car will become stale. The temperature can be controlled with the temperature dial.


    Remember: If the panel vents are open, a certain amount of air will always flow through, regardless of the position the function dial is in. To increase the flow of air to either the floor or the windows, close the panel vents. The outer vents can be opened to avoid mist on the outside windows.
    The air conditioning system will function best if it is used regularly.
    Water under the vehicle in hot weather can be the result of condensation from the air conditioning system.

    Heated front seats (certain models)


    The heated front seats can be switched on and off as required. When switched on, the system senses the ambient temperature and regulates the level of heat applied. When the optimum temperature is reached, the heating is switched off automatically.
    While driving, the passenger seat heating should be switched off when the seat is not occupied.

    pg. 1:17 Electrically operated windows


    Electrically-operated windows


    The electrically operated windows are controlled by switches from the driver's armrest as shown in the above illustration.
    The starting (ignition) switches must be ON (position II) for the electrically operated windows to function. The window is lowered if the rear part of the switch is pressed and raised if the front part of the switch is pressed.
    NOTE: Driver's window only (AUTO): The window can be opened completely by pressing the rear part of the switch lightly and releasing it immediately. The window can be stopped by pressing the button again. If the button is held down, the window will be lowered until the button is released.


    WARNING! Remove the starting (ignition) key when children are left unattended in the vehicle.
    Make sure that children's hands are clear before raising the windows.



    Cut-out switch for rear-door windows


    If the car is equipped with rear door power windows, this function can be disabled by a switch located on the driver's armrest. This switch is positioned 90° in relation to the other switches.
    The rear door windows can be raised or lowered with the respective door switch as well as the switch on the driver's door.
    The rear door windows cannot be raised or lowered with the respective door switch but instead only with the corresponding switch on the driver's door.


    NOTE: The power window motors have an overload protecting circuit breaker which is activated when an object blocks a window. Should this occur, remove the object and wait 20 seconds for the circuit breaker to reset. The power windows should then function.

    pg. 1:18 Parking brake, Cigarette lighter, Ash trays


    Parking brake (hand brake)


    The lever is situated between the front seats. The brake is applied to the rear wheels.


    WARNING!
    Always use the parking brake (hand brake) when parking. On hills, also turn the front wheels toward the curb.


    In order to obtain the best possible performance of the parking brake, the brake linings should be broken in (See section titled "Break-in period").



    Cigarette lighter/accessory outlet


    To operate, depress the knob fully. When the knob automatically releases, the cigarette lighter is ready for use.
    The starting (ignition) switch must be switched on (to position I or II) for the cigarette lighter to function.


    Ash trays


    To remove the ash trays depress the center spring and remove.
