[ i J Tips
If the climate control system is operating in cooling mode, air flows
primarily from the outlets in the center console and in the door
pillars . To achieve adequate cooling, you should never close the
outlets completely. •
Using climate controls economically
Using the climate controls prudently can help save fuel.
When you use the air conditioner, engine power is reduced
and fuel consumption increases. To save fuel, you should
use the air conditione r only when necessary. Also please
n ote the following points:
- If you want to save fuel, activate ECON.
If you are going to drive with the windows open, use
ECON.
W For the sake of the environment
By reducing the amount of fuel you use, you also reduce the amount
of pollutants emitted into the air.•
Applie s to v ehicl es: with so lar slidi ng /tilt ing sunr oof
Solar blower fan /solar roof
With sufficient sunlight, the blower fan continues to
operate with solar energy to bring in fresh air after the
ignition has been switched off.
T he fan motor is operated by solar energy through the solar roof
after the ignition is turned off. Please make certain that vents ©
and © are open to achieve optimal ventilation=>
page 122, fig. 137.
Con tro ls and eq uip­
ment
The ventilation operates only with the sunroof closed or in the tilted
position .
If the vehicle was switched off in the recircu lation mode, the air
conditioning automatically switches to fresh air operation.
