Automatic climate
control (ACC) The ACC system automatically works to
maintain the desired temperature inside the
car.
The system will achieve the desired temper-
ature in the quickest possible way. Note that
selecting a higher or lower temperature than
that desired will not speed up the process.
For the ACC system to be most effective, all
windows (and moonroof3) should be
closed.
Fresh air for the cabin is drawn in through an
inlet grille adjacent to the bottom edge of the
windshield. The air flows through a filter
upstream of the ACC system before deliv-
ery to the cabin. Cabin air is evacuated via
openings in the rear parcel shelf and then
through outlets on either side of the car
behind the rear bumper.
The incoming air is treated in three stages:
first it passes through a filter; it is then dehu-
midified and cooled and, finally, if required,
heated.
The filter is a combined particle and char-
coal filter. It is so efficient that levels of nox-
ious substances such as benzene and tolu-
ene are also reduced.To reduce the likelihood of misting on the
insides of the windows, the glass should be
cleaned with a quality window cleaner. How
often this will need to be done depends on
how clean the air is – if there are smokers in
the car, cleaning will need to be done more
frequently.

81 Instruments and controls
Temperature control The cabin is divided into two temperature
zones:
 The driver’s zone
 The passenger zone (front and rear
seats)
The desired temperature can be set
between 60 and 80°F.
The displayed temperature is not the abso-
lute temperature but corresponds to the
comfort level normally experienced at that
temperature after allowance has been
made for the air flow, relative humidity, solar
radiation, etc., currently prevailing inside
the car.
 The most usual temperature setting is
64–76°F, depending on personal prefer-
ence and what clothing is worn.
 To allow the system time to adjust,
changes in the temperature setting shall
only be made in steps of 2°F.
Once the desired climate has been
achieved, the rear center vents can be
closed to prevent warm air being distributed
at face height.
When the ignition is switched off, only the
temperature control affects the system the
next time the engine is started. The system
will warm up/cool down to the temperature
to which the control is set.MAX heat, red indication
The MAX heat setting is obtained by turning
the temperature control to the first position
past 80 (to the red LED). The driver’s side
selection regulates air distribution and recir-
culation status. Temperature, however, can
be adjusted on the passenger side.
Settings when MAX heat is selected:
 Maximum heat
 Air distribution to windshield and floor
 Recirculation OFF (even if manually
selected before)
 Fan: high speed
MAX cooling, blue indicator
The MAX cooling setting is obtained by turn-
ing the temperature control to the first posi-
tion past 60 (to the blue LED). The driver’s
side selection regulates air distribution and
recirculation status. Temperature, however,
can be adjusted on the passenger side.
Settings when MAX cooling is selected:
 Maximum cooling (A/C compressor will
run even if AC OFF manually selected
before)
 Air distribution through panel vents
 Fan: maximum speed
 Recirculation ON
