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.

B Closed
C Directing air flow horizontally
D Directing air flow vertically

ECC - Electronic Climate Control panel

Blower 0 = off 5 = max speed aut = blower speed automatically regulated	Function selector Set desired function aut = normal setting	Temperature dial Set desired temperature

Air in the passenger compartment recirculates with this button depressed. Will not function in defrost setting. Light is on when recirculation is active*

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.

The air conditioning system in your car contains a CFC-free refrigerant - R134a. This substance will not deplete the ozone layer. 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 SP1 (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.

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.

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.

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.

Parking brake (hand brake)

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

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.
