When using the air conditioning
system, monitor the engine tem-
perature gauge closely while driv-
ing up hills or in heavy traffic
when outside temperatures are
high. Air conditioning system
operation can cause engine over-
heating. Continue to use the blow-
er fan, but turn the air condition-
ing system off if the engine tem-
perature gauge indicates engine
overheating.
Air conditioning system operation
tips
If the vehicle has been parked indirect sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
After sufficient cooling has been achieved, switch back from the
recirculated air to the fresh outside
air position.
To help reduce moisture inside of the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the win-
dows and sunroof closed.
Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance. If you operate air conditioner
excessively, the difference between
the temperature of the outside air
and that of the windshield could
cause the outer surface of the
windshield to fog up, causing loss
of visibility. In this case, set the
mode selection knob or button to
the position and fan speed
control to the lower speed.

tally friendly R-1234yf refrigerant.
1. Start the engine.
2. Push the air conditioning button.
3. Set the mode to the Face Levelmode.

maximum comfort.
When maximum cooling is desired,
set the temperature control to the
extreme left position then set the fan
speed control to the highest speed. When using the air conditioning
system, monitor the engine tem-
perature gauge closely while driv-
ing up hills or in heavy traffic
when outside temperatures are
high. Air conditioning system
operation can cause engine over-
heating. Continue to use the blow-
er fan, but turn the air condition-
ing system off if the engine tem-
perature gauge indicates engine
overheating.
Air conditioning system operation
tips
If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.

recirculated air to the fresh outside
air position.
To help reduce moisture inside of the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the win-
dows and sunroof closed.
Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance.
