Your vehicle is equipped with side window defogger
vents located on the top of the instrument panel.
For additional side window defogging, turn the mode
knob to the BI
- LEVEL setting and adjust the fan to
the highest speed. Aim the side vents on the instrument
panel toward the side windows. For increased airflow to
the side vents, close the center vents.
Operating the HVAC system in the RECIRCULATION
mode may cause fogging of the vehicle’s windows when
the weather is cold and damp. To clear the fog, switch
the HVAC system to either the DEFOG or DEFROST
mode and increase the fan speed. To avoid re
- fogging
of the windows, operate the HVAC system in the
OUTSIDE AIR mode.
For additional information, refer to “RECIRCULATION”
earlier in this section.

The left knob is the fan knob and is used to select and
