The automatic air conditioning system is optional equipment.
IMPORTANT: Use the air conditioning regularly to prevent seizing of the
compressor.
IMPORTANT: When using the air conditioning, keep the cab doors and windows
closed.
The operating temperature of the air conditioning is -40°C...+80°C. The display
decelerates in -30'C and stops working in -40'C.
When operating in cold conditions, the air conditioning stays in the starting mode
until the temperature of the engine coolant reaches +40°C. During the starting
mode the fan speed is at the minimum and the fresh-air intake intake is on. The
starting mode ends when the engine coolant has reached the temperature of
+40°C, or in the following cases:
• defrost is connected
• LO mode is connected
