The heating, cooling, and ventilation for the vehicle can be controlled with
this system. For vehicles with the remote start feature, the climate control
system will turn on with a remote start. See Remote Vehicle Start on page 2-6.

control system off. Press any
button to turn the system on again.
While the climate control system is
off the recirculation and rear window
defogger can still be turned on.
Automatic Operation
AUTO (Automatic): When this
button is pressed, the system
automatically controls the inside
temperature, the air delivery mode,
the air conditioning compressor,
and the fan speed. When AUTO
appears in the display, the system is
in full automatic operation. If any
of the controls are manually
adjusted, the AUTO indicator turns
off in the display.
1. Press the AUTO button, if the
AUTO indicator does not
appear on the display.
2. Adjust the temperature to a
comfortable setting between
72°F (22°C) and 75°F (24°C).
Choosing the coldest or warmest
temperature setting will not
cause the system to heat or cool
any faster.
3. Let the system stabilize for a
few minutes.
4. Adjust the air outlets or
temperature.
In cold weather, the system starts in
the recirculation mode with the
fan off. As the engine warms up,
warm air is directed to the floor
outlets, before automatically
changing to bi-level mode with a
reduced fan speed.
Do not cover the solar sensor
located in the center of the
instrument panel, near the
windshield. For more information
on the solar sensor, see “Sensors”
later in this section.
