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.
