Diagnostic Monitor Completion

The drive cycles detailed here will enable the monitors to run, but only after fuelling adaptations are complete.

Depending on road conditions and dealer location, it may be difficult to achieve the road speeds necessary to reach the air flow indicated. It is possible to reach these air flow figures by inducing a load on the vehicle, (making use of hills, using a lower gear ratio, etc) or, if no alternative is possible, by restraining the vehicle and reaching the air flow figure stationery in D.

During the drive cycle, drive gently, avoiding hard acceleration, braking or cornering and rough roads.
- Drive at 84 to 97 kph (52 to 60 mph) for 40 seconds.
- Accelerate to 113 kph (70 mph).
- Close the throttle, (ideally at the start of a descent) continue with closed throttle for 10 seconds. (Fuel cut)
- Drive at 56 to 64 kph (35 to 40 mph), holding the throttle as steady as possible, on a flat level road for 30 seconds minimum.
