plied, stop the vehicle and perform the fol-
lowing:
1. Check the brake fluid level. Add brake fluid as necessary. For additional infor-
mation, refer to “Brake fluid” in the “Do-

2. If the brake fluid level is correct, have the warning system checked. It is rec-
ommended that you visit a NISSAN
dealer for this service.
WARNING
∙ Your brake system may not be work-ing properly if the warning light 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 en-
gine stopped and/or a low brake fluid
level may increase your stopping dis-
tance and braking will require greater
pedal effort and 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 that you visit a NISSAN
dealer for this service.

indicator
When the parking brake is released and the
brake fluid level is sufficient, if both the
brake warning light and the ABS warning
light illuminate, it may indicate the ABS is
not functioning properly. Have the brake
system checked and, if necessary, repaired.
It is recommended that you visit a NISSAN
dealer for this service. Avoid high-speed
driving and abrupt braking. For additional
information, refer to “Anti-lock Braking Sys-
tem (ABS) warning light” in this section.

control system (if so equipped) and
the vehicle battery may not charge
completely. For additional informa-
tion, refer to “Variable voltage control
system” in the “Do-it-yourself ” sec-
tion of this manual.

Instruments and controls2-25

∙ If the light illuminates while driving,avoid sudden steering maneuvers or
abrupt braking, reduce vehicle speed,
pull off the road to a safe location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and in-
crease the likelihood of tire failure. Se-
rious vehicle damage could occur and
may lead to an accident and could re-
sult in serious personal injury or
death. Check the tire pressure for all
four tires. Adjust the tire pressure to
the recommended COLD tire pressure
show on the Tire and Loading Infor-
mation label located in the driver’s
door opening to turn the low tire pres-
sure warning light off. If the light still
illuminates while driving af ter adjust-
ing the tire pressure, a tire may be flat
or the TPMS may be malfunctioning. If
you have a flat tire, replace it with a
spare tire as soon as possible. If no tire
is flat and all tires are properly in-
flated, have the vehicle checked. It is
recommended that you visit a NISSAN
dealer for this service. ∙ When replacing a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire pres-
sure warning light will flash for ap-
proximately 1 minute. The light will re-
main on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN dealer
for these services.
∙ Replacing tires with those not origi- nally specified by NISSAN could affect
the proper operation of the TPMS.
CAUTION
∙ The TPMS is not a substitute for theregular tire pressure check. Be sure to
check the tire pressure regularly.
∙ If the vehicle is being driven at speeds of less than 16 mph (25 km/h), the
TPMS may not operate correctly.
∙ Be sure to install the specified size of tires to the four wheels correctly.
Low windshield-washer
fluid warning light (if so
equipped)

washer fluid is at a low level. Add
windshield-washer fluid as necessary. For
additional information, refer to “Windshield-
washer fluid” in the “Do-it-yourself ” section
of this manual.
Malfunction warning light(red) (if so equipped)
If this warning light illuminates this indi-
cates either the coolant temperature is
above a critical threshold or the exhaust
temperatures are above a critical thresh-
old. When illuminated this lamp indicates
the need to stop the engine as soon as it
can be safely done. The engine must re-
main shut down until the engine can be
repaired. For additional information, refer
