When you set the temperature to its
lower limit (
) or its upper limit
(
), the system runs at full cooling
or heating only. It does not regulate
the interior temperature.
When you press a fan control button,
the fan is taken out of AUTO mode.
When the indicator in the dual
button is on, the driver's side and
passenger's side temperature can be
controlled independently (see page
177).
When the indicator in the rear button
is on, the temperature of the rear
passenger compartment can be
controlled independently (see page
177).
On models with navigation systemIn the Auto mode, the vehicle's
interior temperature is independently
regulated for the driver, front
passenger, and rear passengers
according to each adjusted
temperature. The system also
regulates each temperature based on
the information of the sun light
sensor and the sun's position which
is updated automatically by the
navigation's global positioning
system (GPS). For example, if the
driver's side of the vehicle is getting
too much sun, the system will adjust
to a lower temperature.
Dual ButtonYou can set the temperatures for the
driver's side and the passenger's side
separately when this button is
pressed (indicator is on). When the
indicator in the DUAL button is off,
the temperatures for both sides are
synchronized to the driver's side set
temperature. When defrost mode is
selected, dual mode operation is
canceled.
