Sensors
The automatic regulation of the air conditioning inside the cabin uses a number of sensors that relieve you of the need to make adjust-ments outside the displayed tem-perature.
Be careful not to obstruct the sun-light sensor located on the dash-board.
Air inlet
Check that the exterior grille for the air inlet, at the bottom of the windscreen, is clean and free of dead leaves, snow, etc.
Air vents
The air vents to the face have grilles and thumbwheels so that you can a d j u s t t h e a i r fl o w a n d d i r e c t i o n (up-down, right-left).
Air circulation
A i r v e n t s o n t h e fl o o r u n d e r n e a t h the front seats provide enhanced heating for the rear seat positions : take care not to obstruct them.
D u s t fi l t e r / o d o u r fi l t e r (active carbon)
T h e r e i s a fi l t e r f o r e x c l u d i n g o d o u r s and dust.
T h i s fi l t e r h a s t o b e c h a n g e d i n accordance with the vehicle main-tenance schedule (see the Main-tenance Guide).
Air conditioning
To ensure that your system oper-ates correctly, it is recommended to have it checked regularly.
Water arising from condensation in the air conditioning drains away through a hole provided for this purpose. A pool of water may thus form under the vehicle when sta-tionary.
To keep the air conditioning com-pressor well sealed, it is essential to operate the air conditioning at least once in every month.
To be effective, the air condition-ing should only be used with the windows closed.
If after a lengthy stop in bright sunlight the interior temperature is excessive, ventilate the passen-ger compartment by opening the windows for a few moments, then close them again.
The air conditioning operates by using power from the engine. This results in a slight increase in fuel consumption.
