when needed.
Prolonged operation of the heater in
Recirculation mode and without the A/C
ON can cause fogging of the windshield.

in Recirculation mode may result in
excessively dry, dehumidified air in the
cabin and may promote formation of
musty vent odor due to stagnant air.

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.
