following warning light illuminate at the
same time when the parking brake is re-
leased and the brake fluid level is sufficient,
there may be a malfunction in the brake
system.
. Brake system warning light (yellow)
WARNING
If both the brake system warning light
(yellow) and the brake warning light
(red) illuminate when the parking brake
is released and the hybrid system is on,
do not drive the vehicle. More brake
pedal effort than normal will be required
and there will be a significant reduction
in brake performance, which could result
in an accident. Immediately stop the
vehicle in a safe location and it is
recommended you contact an INFINITI
retailer.
A chime sounds if a malfunction occurs in the brake system power supply.

Anti-lock Braking System (ABS) warning
light
— Avoid driving at high speed and sud-
den braking, and see an INFINITI
retailer as soon as possible for an
inspection.
WARNING
.Your brake system may not be work-
ing properly if the brake warning
light (red) is on. Driving could be
dangerous. If you judge it to be safe,
drive carefully to the nearest service
station for repairs. Otherwise, have
your vehicle towed because driving it
could be dangerous.
. Pressing the brake pedal with the
hybrid system stopped and/or low
brake fluid level may increase your
stopping distance and braking will
require greater pedal effort as well as
pedal travel.
. If the brake fluid level is below the
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.
