occur when the a ir conditioning
system starts, the air flow mode
may change to blow air to the feet
or air may stop blowing for a short
period of time immediately after
the air conditioning system is
started in automatic mode.
●When parking, the system auto-
matically switches to outside air
mode to encourage better air cir-
culation throughout the vehicle,
helping to reduce odors that occur
