HEATING AND AIR CONDITIONING

Two air conditioning systems are available: the large
capacity (central HVAC system) or the small
capacity A/C (small HVAC system). Vehicles
equipped with the large capacity HVAC system
benefit from a combination heating and cooling
system
conditioned and filtered air for all climatic conditions.
Fresh air is drawn into the system from the left
(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 central
unit. An air mixture selector enables air to be drawn
into the system from outside the vehicle or
recirculated. Driver's air provides cooling for the
driver's area only, maximizing available baggage
space for other uses. The small capacity HVAC
system enables cooling the driver's area only.
