Climate Control
WARNING
To prevent property damage, personal injury, and / or death, never drive the vehicle unless the windshield and all other windows
are clear. A fogged, ice / snow covered, or dirty windshield or window limits vision, which could cause an accident. To improve
defroster efficiency, remove ice and / or snow by hand from the windshield and windows with a non-metallic scraper.
CAUTION
To prevent property damage and to clear system of humid air, operate blowers for 30 seconds at high speed, with the AIR FLOW
/ AIR CONDITIONER knob on the normal heating position before selecting the DEF position. This will prevent fogging the glass,
which can occur if humid air is blown onto a cool windshield.
NOTE: The vehicle may be equipped with heater shutoff valve(s) to prevent hot coolant from circulating through the heater core(s). Closing
the valve(s) during hot weather operation will improve A/C system performance. If the valves are shut off, in-cab temperature adjustment
may become limited. In addition, when shutoff valves are closed, defrosters will produce only cold air.

air from entering the vehicle. Turning off the fan speed control also turns off the A/C compressor.
