WARNING
• Your brake system may not be working
properly if the warning light is on. Driv-
ing 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 engine
stopped and/or a 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 MINI-
MUM or MIN mark on the brake fluid
reservoir, do not drive until the brake
system has been checked. It is recom-
mended that you visit an INFINITI re-
tailer for this service.

If this light comes on while the engine is run-
ning, it may indicate the charging system is
not functioning properly. Turn the engine off
and check the generator belt. If the belt is
loose, broken, or missing or if the light re- mains on, have the system checked. It is rec-
ommended that you visit an INFINITI retailer
for this service.
CAUTION
Do not continue driving if the generator
belt is loose, broken or missing.

ous damage to the engine almost immedi-
ately. Such damage is not covered by war-
ranty. Turn off the engine as soon as it is

and remains illuminated until the driver's seat
belt is fastened. At the same time, the chime
sounds for about 6 seconds unless the driv-
er's seat belt is securely fastened.

tems” (P. 2-29).

position, the supplemental air bag warning
light illuminates for about 7 seconds and then
