Nominal Values For Pressures And Temperatures

NOTE: The temperature of the air from the center dashboard vents must lie within the prescribed tolerance range within 5 minutes, depending on the ambient temperature.

General Test Prerequisites

- Close doors, windows and sliding roof.
- Insert temperature probe into center vent.
- Measure ambient temperature.
- Open all dashboard vents.
- Switch ignition on.
- Press circulation button.
- Set temperature control to maximum cooling.
