Chrysler 2004 PT Cruiser Automobile User Manual

NOTE: If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser: located in front of the radiator, for an accumula-
tion of dirt or insects. Clean with a gentle water spray
from behind the radiator and through the condenser.
Fabric front fascia protectors may reduce air flow to the
condenser, reducing air conditioning performance.
Circulation Control
Use this control to choose be-
tween outside air intake or
recirculation of the air inside
the vehicle. Only use the re-
circulate mode to temporarily
block out any outside odors,
smoke, or dust and to cool the
interior rapidly upon initial
start up in very hot or humid
This control only operates in the Outside Air and Recir-
culate modes; there is no in between position. Do not
place the control between these positions.
NOTE: Continuous use of the recirculate mode may
make the inside air stuffy and window fogging may
occur. Extended use of this mode is not recommended.
In cold or damp weather, the use of the Recirculate
position will cause windows to fog on the inside because
of moisture build up inside the vehicle. For maximum
defogging, select the Outside Air position.
If the mode control is in the range between Mix and
Defrost and you choose the recirculate mode, the mode
control knob will automatically move to the left of the
Mix position.
NOTE: If you choose Defrost mode and the Circulation
control is in the recirculate Mode, the system will auto-
matically switch to the Outside Air mode and the knob
will move to that position.
