HEATING, VENTILATION AND AIR-CONDITIONING
SYSTEM (HVAC)
HVAC system provided in the vehicle enables occupants to
automatically/manually adjust air flow distribution pattern,
air flow rate, air intake mode and air temperature inside
passenger compartment. By appropriately adjusting the
control knobs/switches provided on the HVAC control panel,
located on center console, occupant’s comfort can be
ensured. HVAC system also helps in defrosting and defogging/
de-misting the windshield and windows.
Air flow direction can be further controlled by adjusting
louvers of air vents. An air filter is provided at the inlet of
HVAC blower.
Engine coolant is utilized to heat the cabin air. For cooling the
cabin air, an air conditioning circuit based on the vapor
compression refrigeration cycle is used. The air conditioning
system uses a refrigerant along with a suitable lubricating oil.
Although being non-ozone depleting, the refrigerant is a
greenhouse gas, hence once allowed to escape in the
atmosphere, it adversely affects the environment by contrib-
uting to global warming/climate change.
WARNING
!
Refrigerant used in system is a hazardous liquefied
gas and is under high pressure. The refrigerant is
colorless and has ethereal or faint sweetish odor.
Exposure of refrigerant to skin or eyes may cause
irritation and frostbite. They can also cause
suffocation, dizziness and loss of concentration. When
mixed with compressed air or certain other
refrigerants, it may form flammable mixture. Never
try to service HVAC system yourself which would
involve refrigerant handling.
Multiple vents are provided for distributing the air, being
force-circulated by HVAC blower, throughout the passenger
compartment.
NOTICE
To ensure sufficient air flow and hence adequate HVAC
system performance, air flow path should be kept free
of obstructions. Keep system’s air intake, located
near plenum appliqué, free of snow, leaves and other
debris. Also keep the area in front of air vents free of
any obstruction inside the cabin.
