Vents, Heating, and A/C
Air Conditioning (A/C) Button
Press the A/C button to turn the air
conditioning on and off. You will see
A/C ON or A/C OFF in the display.
When you turn the A/C off, the
system cannot regulate the inside

temperature control below the
outside temperature.

Recirculation Button
When the recirculation indicator is
on, air from the vehicle's interior is
sent throughout the system again.
When the indicator is off, air is
brought in from the outside of the
vehicle (fresh air mode).
The outside air intakes for the
heating and cooling system are at
the base of the windshield. Keep this
area clear of leaves and other debris.
The system should be left in fresh
air mode under almost all conditions.
Keeping the system in recirculation
mode, particularly with the A/C off,
can cause the windows to fog up.
Switch to recirculation mode when
driving through dusty or smoky
conditions, then return to fresh air
mode.
Mode Control
Use the mode control buttons to
select the vents air flows from. Some
air will flow from the dashboard
corner vents in all modes.
Each time you press the MODE
button (On RTS, RTL, and Canadian
EXL models) or either mode button
(On RT, RTX, and Canadian LX
models), the display shows the mode
selected.
Air flows from the center,
corner, and rear vents in the
dashboard.
Airflow is divided between
the vents in the dashboard, rear and
the floor vents.
Air flows from the floor
vents.
