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
