Nissan Sentra Owners Manual: Heater and Air Conditioner (manual) (if so equipped)
WARNING
- The air conditioner cooling function operates
only when the engine is running.
- Do not leave children or adults who would
normally require the assistance of others
alone in your vehicle. Pets should also not
be left alone. They could accidentally injure
themselves or others through inadvertent
operation of the vehicle. Also, on
hot, sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly fatal
injuries to people or animals.
- Do not use the recirculation mode for
long periods as it may cause the interior
air to become stale and the windows to
fog up.
