The headphones receive two separate channels of audio
using an infrared transmitter from the video screen.
Front seat occupants receive some headphone audio
coverage to allow them to adjust the headphone volume
for the young rear seat occupants that may not be able to
do so for themselves.
If no audio is heard after increasing the volume control,
verify that the screen is turned on and in the down
position and that the channel is not muted and the
headphone channel selector switch is on the desired
channel. If audio is still not heard, check that fully
charged batteries are installed in the headphones.

NOTE:
•In Floor, Mix and Defrost modes a small amount of air
will flow through the outboard panel outlets for
occupant comfort.
•The air conditioning compressor operates in Mix,
Defrost, or a blend of these modes, even if the Air
Conditioning (A/C) button is not pressed. This dehu-
midifies the air to help dry the windshield. To improve
fuel economy, use these modes only when necessary.
Recirculation Control Pressing the Recirculation Control button will
put the system in recirculation mode. This can
be used when outside conditions such as
smoke, odors, dust, or high humidity are pres-
ent. Activating recirculation will cause the LED in the
control button to illuminate. NOTE:
•Continuous use of the Recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.
•The use of the Recirculation mode in cold or damp
weather could cause windows to fog on the inside,
because of moisture buildup inside the vehicle. Select
the outside air position for maximum defogging.
•The A/C will engage automatically to prevent fogging
when the recirculation button is pressed and the mode
control is set to panel or panel / floor.
•The A/C can be deselected manually without disturb-
ing the mode control selection.
•When the ignition switch is turned to the LOCK
position or the ignition switch START/STOP button is
cycled to OFF, the recirculation feature will be
cancelled.

(EVIC displays “IGNITION MODE RUN”),
•Press the ENGINE START/STOP button a third time
to return the ignition switch to the OFF position (EVIC

Extreme Cold Weather (Below –20°F Or29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle. If the vehicle has a discharged battery,
booster cables may be used to obtain a start from a
booster battery or the battery in another vehicle.
This type of start can be dangerous if done improp-
erly. Refer to “Jump Starting” in “What To Do In
Emergencies” for further information.
