dealer for this service.
Anti-lock Braking System (ABS) warning
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.
Charge warning light
If this light comes on while the engine is
running, it may indicate the charging sys-
tem is not functioning properly. Turn the
engine off and check the generator belt. If
the belt is loose, broken, missing, or if the
light remains on, have the system checked.
It is recommended that you visit a NISSAN
dealer for this service.
CAUTION
∙ Do not ground electrical accessories directly to the battery terminal. Doing
so will bypass the variable voltage
control system and the vehicle bat-
tery may not charge completely. For
additional information, refer to “Vari-
able voltage control system” in the
“Do-it-yourself ” section of this
manual.
∙ Do not continue driving if the genera- tor belt is loose, broken or missing.
Low tire pressure warning
light
Your vehicle is equipped with a Tire Pres-
sure Monitoring System (TPMS) that moni-
tors the tire pressure of all tires except the
spare.
The low tire pressure warning light warns
of low tire pressure or indicates that the
TPMS is not functioning properly.
Af ter the ignition switch is placed in the ON
position, this light illuminates for about
1 second and turns off. Low tire pressure warning
If the vehicle is being driven with low tire
pressure, the warning light will illumi-
nate. A “Tire Pressure Low - Add Air”
warning also appears in the vehicle in-
formation display.
When the low tire pressure warning light
illuminates, you should stop and adjust
the tire pressure of all four tires to the
recommended COLD tire pressure shown
on the Tire and Loading Information la-
bel located in the driver’s door opening.
The low tire pressure warning light does
not automatically turn off when the tire
pressure is adjusted. Af ter the tire is in-
flated to the recommended pressure,
the vehicle must be driven at speeds
above 16 mph (25 km/h) to activate the
TPMS and turn off the low tire pressure
warning light. Use a tire pressure gauge
to check the tire pressure.
The “Tire Pressure Low - Add Air” warning
appears each time the ignition switch is
placed in the ON position as long as the low
tire pressure warning light remains illumi-
nated.

∙ Radio waves could adversely affectelectric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
∙
If the light does not illuminate with the
ignition switch placed in the ON posi-

as possible. It is recommended that you
visit a NISSAN dealer for this service.
∙ 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.
