To find your comfort setting, start with a 72°F (22°C)
temperature setting and allow about 20 minutes
for the system to adjust. Turn the driver or
passenger side temperature knob to adjust the
temperature setting as necessary. If a temperature
setting of 60°F (15°C) is chosen, the system will
remain at the maximum cooling setting. If a
temperature setting of 90°F (32°C) is chosen, the
system remains at the maximum heat setting.
Choosing either maximum setting may not cause
the vehicle to heat or cool any faster.
