Operating Check
WARNING: This page is about a different car, the 2008 Infiniti QX56. However, it is still accessible from the selected car via links, so may be relevant.
With engine stopped, change the vacuum to the atmospheric pressure by depressing brake pedal several times. Then with brake pedal fully depressed, start engine and when the vacuum pressure reaches the standard, make sure the clearance between brake pedal and floor panel decreases.
CAUTION:
Depressing pedal interval is approximately 5 seconds.
