If the climate control system is operating
in cooling mode, a ir flows primarily from
the outlets in the center conso le and in the

you should never close the outlets com
pletely .
Using climate control economically
Using the climate controls prudently can help
save fuel.
When you use the air conditioner, engine pow
er is reduced and fuel consumption increases.
To save fuel, you should use the air condition
e r only when necessary. Also please note the
following points :
.,. To save fuel, turn off cooling mode by press
ing the
I AC ! button (indicator light goes
out) .
.,. In add ition, if you open the window or the
Panoramic sliding sunroof* while driving,
turn off cooling mode by p ress ing the
IACI
button (indicator light goes out).
.,. If the vehicle is extremely hot due to the
heat of the sun, briefly open doors and win
dows.
@ For the sake of the environment
By reducing the amount of fue l you use,
you also reduce the amount of poll utants
emitted into the air. W

Automatic recirculation mode
An air quality sensor detects increased con
centrations of pollutants in the outside air
and automatically switches to recirculation
mode .
We recommend that you always keep auto
matic a ir recirculation ON to p revent polluted
outside air from enteri ng the veh icle inter ior.
If the
a ir qu ality sensor l ocated in the air con
ditioning system detects polluted outs ide a ir,
the sensor dec ides whether the air pollut ion
can be reduced by the facto ry-installed pollu
ta nt fi lter or whethe r it is necessary to switc h
to air recirc ulation. With heavy conce ntra ti ons
of pollu tants, the a ir condit ion ing system is
switched automatica lly to recirc ulation mode
and the supp ly of outside air is blocked . As
soon as the concentration of pollutants in the
outside air drops, fresh air is supplied to the
vehicle interior aga in.
In the event that the windows fog up during
automat ic air rec irculat ion, you must press
the® button immediately.
Under certa in ope rating cond itions, a utomatic
air recirculation is switched off automatica lly.
With outside temperatures be low about 50 °F
(+10 °C), automatic air rec irculat ion is limited
to 30 seconds. W it h outside temperatures be
low about 30 °F ( -1 °C) a nd with the air condi
