Tips: Using Air Conditioner System

Operation Gist

● To quickly cool the car exposed in
the hot sun, please drive for several
minutes with windows opening.
● Make sure the air inlet grid in front
of windshield is not blocked by things
such as leaves or snow.
● In wet weather, do not let cooling
air blow onto the windshield. Due to
temperature difference between the
outside and inside of windshield, the
windshield will be fogged.
● Always keep clear under the front
seat so as to make the air fully
recycling in car.
● In cold weather, set the high rotating
speed of blower for one minute so as
to clear the snow or moisture in the
air inlet channel, as it will reduce the

possibility of fogging on the windows.
● If driving behind other cars on a road
which is not clean, or driving in the
wind and dust, you are recommended
to set internal-external recycling mode
selecting button to internal recycling
temporarily and set the rotating
speed of blower to a proper speed.
