Information
Using the system primarily in Fresh mode
and Recirculation mode only when needed
is recommended for best results.
Prolonged operation of the heater in
Recirculation mode and without the A/C
ON can cause fogging of the windshield.
In addition, prolonged use of the A/C
ON in Recirculation mode may result in
excessively dry, dehumidified air in the
cabin.
WARNING
• Continued use of the climate control
system operation in Recirculation
mode for a prolonged period of
time may cause drowsiness to the
occupants in the cabin. This may lead
to loss of vehicle control which may
lead to an accident.
• Continued use of the climate control
system operation in Recirculation
mode with the A/C OFF may allow
humidity to increase inside the
cabin. This may cause condensation
to accumulate on the windshield and
obscure visibility.
• Do not sleep in your vehicle or
remain parked in your vehicle with
the windows up and either the
heater or the air conditioning ON for
prolonged periods of time. Doing so
may increase the levels of carbon
dioxide in the cabin which may lead
to serious injury or death.
Fan speed control
ODN8A059113ODN8A059113

Operation Tips
• To keep dust or unpleasant fumes fr
om entering the vehicle through the
ventilation system, temporarily set
the air intake control to recirculation
mode. Return the control to Fresh
mode when the unpleasant air outside
has diminished. This will help keep the
driver alert and comfortable.

intake control to fresh mode and fan
speed to the desired position, turn

system is filled with R-1234yf refrigerant.
1. Start the engine.
2. Press the air conditioning button.
3. Set the mode to the Face Level

mode.
4. Set the air intake control to Recirculation mode temporarily to
allow the cabin to cool quickly. When
the desired temperature in the cabin
is reached, change the air intake
control back to Fresh mode.
5. Adjust the fan speed control and temperature control to maintain
maximum comfort.
When maximum cooling is desired, set
the temperature control to the MAX A/C
position, then set the fan speed control
to the highest setting.
NOTICE
When using the air conditioning system,
monitor the engine temperature gauge
closely while driving up hills or in heavy
traffic when outside temperatures are
high. Air conditioning system operation
when climbing a steep grade or in high
outside ambient temperatures can
cause engine overheating.
Continue to use the fan, but turn the air
conditioning system off if the engine
temperature gauge indicates engine
overheating.
