TEST DRIVE (details of procedure)
:
Preferably test drive the vehicle after it has been left unused overnight. The difference between the engine
temperature and ambient temperature on starting must be between 3°C and 37.5°C, and the fuel level
must be between 15% and 85%.
Self-adaptive parameters must be reset (simply cancel errors to reset).
TEST DRIVE procedure

With the engine cold, start the engine and leave to idle for 4 minutes without accelerating.
