Convenient features of your vehicle
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
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.
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.
• After sufficient cooling has been
achieved, switch back from recir-
culation mode to fresh mode.
• 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 lowest speed.
System Maintenance
Cabin air filter

is being driven in severe conditions
such as dusty or rough roads and/or
if transporting pets or occupants
smoke inside the vehicle, then more
frequent cabin air filter inspections
and changes are required.
If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized retailer of Genesis
Branded products.
