Climate Controls

Dual Automatic Climate Control
System
The heating, cooling, and ventilation in your vehicle can
be controlled with this system. Your vehicle also has
a flow-through ventilation system described later in this
section.
Different climate control settings can be selected for the
driver and passengers.
Driver's Side Temperature Control
The driver's side temperature buttons are used to adjust
the temperature of the air coming through the system on
the driver's side. The temperature can be adjusted even if
the system is turned off. This is possible since outside air
will always flow through the system as the vehicle is
moving forward unless it is set to recirculation mode. See
"Recirculation" later in this section.
Press the + or − buttons to increase or decrease the
cabin temperature. The driver side temperature display
will show the temperature setting decreasing or
increasing.
Passenger's Side Temperature Control
The passenger's temperature buttons can be used to
change the temperature of the air coming through
the system on the passenger's side of the vehicle. The
temperature can be adjusted even if the system is
turned off. This is possible since outside air will always
flow through the system as the vehicle is moving
forward unless it is set to recirculation mode. See
"Recirculation" later in this section.
Press the + or − buttons to increase or decrease the
cabin temperature. The passenger side display will show
the temperature setting decreasing or increasing.
