toward the passenger. The passenger’s temperature
setting can be set to match and link to the driver’s
temperature setting by pressing and holding the AUTO
button for three seconds. When adjusting the driver’s
side temperature setting, the passenger’s side
temperature setting will follow and both arrows will
appear on the display. The passenger’s side
temperature setting also resets and relinks to the
driver’s side temperature setting if the vehicle has been
off for more than three hours.
Outside Air Temperature Display
A new outside temperature reading will be displayed if
the vehicle has been off for more than three hours.
If the vehicle has been off for less than three hours,
the old temperature reading may be displayed because
underhood heat is affecting the true outside temperature.
Underhood heat can also affect the outside temperature
while the engine is running. It may also take several
minutes of driving before the display updates to
the actual outside temperature.
Automatic Operation
AUTO (Automatic):
When automatic operation is
active, the system will control the inside temperature,
the air delivery mode, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the air conditioning
operation and air outlet mode will be automatically
controlled. The air conditioning compressor will run
continuously when the outside temperature is over
approximately 40°F (4°C). The air inlet will normally
be set to outside air. If it’s hot outside, the air inlet will
automatically switch to recirculate inside air to help
quickly cool down your vehicle.
2. Set the driver’s and passenger’s temperature.
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’s or
passenger’s side temperature knob to adjust the
temperature setting as necessary. If you choose the
temperature setting of 60°F (15°C), the system
will remain at the maximum cooling setting. If you
choose the temperature setting of 90°F (32°C),
the system will remain at the maximum heat setting.
Choosing either maximum setting may not cause
the vehicle to heat or cool any faster.
