HEATING AND AIR CONDITIONING
A large capacity central HVAC system provides
enough conditioned and filtered air for all climatic
conditions. Fresh air is drawn into the system
from the evaporator compartment on driver’s side
of the vehicle. Return air is taken from the middle
of the vehicle. The driver’s heater and defogger
are controlled separately from the passenger's
unit. An air mixture selector enables air to be
drawn into the system from outside the vehicle or
recirculated.
