At low ambient temperatures and a cold engine, air may not flow into the passenger compartment through the lower air vents for 150 seconds (maximum). This is not a sign of a malfunction. After the engine has warmed up sufficiently, normal warm air flow through the lower air vents will begin.
When using the air conditioner, keep all windows and the sunroof closed.
After parking your car in the sun, drive for two to three minutes with the windows open to quickly remove the hot air from the car. Then close the windows so the air conditioner can cool the air in the car faster.
The air conditioner should be turned on at least once a month and run for about 10 minutes. This will prevent the air conditioner from failing due to lack of lubrication.
If the coolant temperature gauge needle has reached the "Hot" mark (high temperature), turn off the air conditioner.
If the coolant temperature rises significantly, the air conditioner will switch off automatically. This can happen, for example, if the engine is idling for a long time on a hot day.
