with this mode active may lead to better fuel economy and longer
HVAC filter life.
However, running the air conditioner in the re-circulation mode for
long will make the cabin air too dry and the oxygen level drops inside
cabin turning the air stale. On the contrary, keeping air intake
control in the recirculation mode for long, with the air conditioner
switched OFF, will make the cabin air too humid and the windshield/
windows are more likely to become foggy.
The re-circulation mode is activated by default every ignition
cycle.

Auto Re-circulation logic is applicable to extreme cold and extreme
hot setting of the temperature control system.
•
In extreme cold setting — Forced re-circulation mode is activated
automatically
•
In extreme hot setting — Forced fresh air mode is activated
automatically
To change to fresh air mode while in extreme cold setting;
•
For manual climate control systems — Press the air intake
control switch once, the fresh air mode is activated for next 20
sec, after which it switches back to re-circulation mode
automatically. To permanently switch to fresh air mode, press
and hold the air intake control switch for 7 sec.
•
For auto climate control systems — Press the air intake control
switch once. It stays in this mode till you manually shift back to
re-circulation mode.
The same logic is applicable to extreme hot setting also where
fresh air mode is activated automatically.

Your vehicle’s HVAC system is equipped with an air filter at the
blower inlet just behind the glove box. Before getting sucked-in by
the blower, air passes through this filter element. Dirt and other
foreign particles get trapped inside the filter. Clean air is then
circulated through the HVAC unit and into the cabin.
The HVAC filter gets clogged after long use. The clogged filter will
reduce the air flow rate, thereby the air-conditioning and heating
efficiencies will be drastically reduced. Even the windshield/
windows may begin to mist/fog-up easily.
To maintain optimum HVAC system performance, replace the filter
element as per recommended maintenance schedule. However
while operating in highly dusty or polluting conditions, the filter may
require early replacement. If the air flow seems to have
considerably reduced, get the filter replaced immediately.
