is necessary, add fluid and have the
system checked. It is recommended you

INFINITI retailer. (See “Brake fluid”
(P.8-10).)
2. If the brake fluid level is correct, have the warning system checked. It is recom-
mended you have this service performed

indicator:

brake fluid level is sufficient, if both the
brake warning light and the Anti-lock Brak-
ing System (ABS) warning light illuminate, it

minimum or MIN mark on the brake
fluid reservoir, do not drive until the
brake system has been checked. It is
recommended you visit an INFINITI
retailer for this service.
