SMALL HVAC SYSTEM CONTROL MODULE
22333
The vehicle is slightly pressurized by the central
HVAC system to prevent dust and moisture from
entering. Air flow and controls divide the vehicle
into two areas: driver’s area with defroster and
cabin area.
Fresh air is fed in each area and has a separate
return air and discharge air duct.
WARNING
Warm temperatures may cause drowsiness and
affect alertness while driving. For optimum
driving conditions, keep temperature between
68°F and 72°F (20°C to 22°C).
NOTE
To operate the air conditioning system when
stationary, run engine at fast idle. When the A/C
system is running, keep windows and door
closed.
To prevent battery run-down, the A/C and heating
systems will not operate if the charging system is
not working properly.
When the A/C system is running, park at least 4
feet (1,5 m) from other vehicles or buildings to
allow sufficient air flow through the condenser
core.
