AUXILIARY A/C-HEATER CONTROLS (IF EQUIPPED)
Your vehicle may be equipped with auxiliary climate controls. These
allow the front or rear seat passengers to control airflow direction,
temperature and fan level of the rear compartment to quickly heat or
cool the vehicle.
Auxiliary climate controls are located in the first row overhead console
and in the floor console on the back of the front row console.
If the main climate control system is in the OFF position, the auxiliary
climate control will not operate.
The auxiliary unit can be controlled either by the front seat occupant(s)
using the front auxiliary control or by the rear seat passenger(s) using
the rear auxiliary control but not both. To control the auxiliary unit using
the rear control, the front auxiliary blower control must be in the REAR
position.
Front auxiliary controls:
1. Temperature control:
Determines airflow temperature in
the rear of the vehicle. If the main
climate control system is cooling in
MAX A/C or
mode, the
auxiliary temperature control will
not function as the entire vehicle
will operate at a full cool
temperature.
2. Mode selector: Press to select
air flow direction to (Floor) or (Panel).
Directs air to the floor of the third row seating.
directs air to the overhead registers of the second and third row
seating. The selected mode will illuminate on the temperature control.
