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 that provides adequate capacity of
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.
