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 fixture 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.

Refrigerant

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.
