2. Set the driver's and passenger's temperature.
To find your comfort setting, start with a 74°F
(23°C) temperature setting and allow about
20 minutes for the system to regulate. Use the
driver's or passenger's temperature buttons to
adjust the temperature setting as necessary. If
you choose the temperature setting of 60°F
(15°C), the system remains at the maximum
cooling setting. If you choose the temperature
setting of 90°F (32°C), the system remains at
the maximum heat setting. Choosing either
maximum setting will not cause the vehicle to
heat or cool any faster.
Be careful not to cover the solar sensor located on
the top of the instrument panel near the windshield.
This sensor regulates air temperature based on sun
load. For more information on the solar sensor, see
"Sensors" later in this section.
To avoid blowing cold air in cold weather, the
system delays turning the fan on until warm air is
available. The length of delay depends on the
engine coolant temperature. Pressing the
fan switch overrides this delay and changes the
fan to a selected speed.
