Information
Operating the system primarily in Fresh
mode is recommended. Use Recirculation
mode temporarily only when needed.
Prolonged operation of the heater in Recir-
culation 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 exces-
sively dry, dehumidified air in the cabin
and may promote formation of musty vent
odor due to stagnant air.
WARNING
• Continued use of the climate con-
trol system operation in Recirculation
mode for a prolonged period of time
may cause drowsiness to the occu-
pants in the cabin. This may lead to
loss of vehicle control which may lead
to an accident.
• Continued use of the climate con-
trol system operation in Recirculation
mode with the A/C OFF may allow
humidity to increase inside the cabin.
This may cause condensation to accu-
mulate 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 pro-
longed periods of time. Doing so may
increase the levels of carbon dioxide
in the cabin which may lead to serious
injury or death.
