Never operate the HVAC system with the filter removed. This may result in
premature failure of system components.
10.12 Air-Conditioner ON
The air conditioning system can be switched ON/OFF by operating the ‘AC LO’ and
‘AC HI’ switches for manual HVAC system and by AC button in auto climate control
system. An indicator lamp is also incorporated on the switches. The air conditioner is
operational only when both the engine and blower are running.
When the air conditioner is ON, air gets cooled and de-humidified before being
circulated inside the cabin. In hot weather conditions, it will take slightly longer to cool
the interior as compared to cooler weather. Fuel consumption will be relatively
higher if the vehicle is being driven with the air conditioner.

•
In certain operating conditions when the engine gets overheated, the engine
management system may switch off the air conditioner intermittently
•
Occasionally the air conditioner might not actually be functioning even when
the LED on the AC switch remains illuminated. This is to be considered as
normal AC system operation
•
During extreme cold weather conditions, the air conditioner may not function
until the temperature of the air near the evaporator rises above a pre-
defined threshold
•
When the air conditioner is ON, moisture is extracted from the air. The
resulting condensate is drained off from the vehicle. It is therefore normal, if
you see a small pool of water under your vehicle
•
The air conditioner should be operated at least for ten minutes once every
fortnight, even during winter months. This allows the AC system components
to get lubricated periodically and ensures optimum system performance
In the manual HVAC system, the AC HI function has a lower temperature cut-off
than the AC LO function.
