Recirculation
Press this switch to engage the recirculation
function (air in the passenger compartment
recirculates – no fresh air enters the compart-
ment). The LED in the switch will light up to
indicate that the function is engaged.

Use this function if the outside air is con-
taminated with exhaust gases, smoke,
etc or to heat/cool the vehicle quickly.
•
Recirculation should not be used for more
than 15 minutes. If your windows begin to
fog or mist, make sure that the recircula-

recirculation button for at least 3 seconds
to activate a recirculation timer mode.
The amber LED in the recirculation button
will flash 5 times to show that the timer
mode is being activated. In timer mode,
each time the recirculation button is
pressed, the climate control system will
recirculate the air in the passenger com-
partment for 5 – 12 minutes, depending
on the outside air temperature, and then
revert back to fresh air.
•
Timer mode deactivation: Press and hold
the recirculation button for 3 seconds.
The amber LED in the recirculation button
will illuminate steadily for 5 seconds to
show a return to "normal" mode.

In normal mode, when the recirculation
button is pressed, the climate control
system will recirculate the air in the pas-
senger compartment until the recircula-
tion button is pressed again.
•
Timer mode memory: If the vehicle is
turned off while timer mode is active,
timer mode will still be active when the
vehicle is restarted.

tions will still be controlled automatically.
