Low brake fluid warning light
When the ignition switch is placed in the ON
position, the light warns of a low brake fluid level.
If the light comes on while the engine is running,
with the parking brake not applied, stop the ve-
hicle and perform the following:1. Check the brake fluid level. Add brake fluid as necessary. For additional information, re-
fer to “Brake fluid” in the “Do-it-yourself”
section of this manual.
2. If the brake fluid level is correct, have the warning system checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
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 driv-
ing 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 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 that you visit a NISSAN
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 illumi-
nate, 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 addi-
tional 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 system is not func-
tioning 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 sys-
tem checked. It is recommended that you visit a
NISSAN dealer for this service.
CAUTION
● Do not ground electrical accessories di-
rectly to the battery terminal. Doing so

Low tire pressure warning
If the vehicle is being driven with low tire
pressure, the warning light will illuminate.
A CHECK TIRE PRES (pressure) warning
message is also displayed in the odometer.
When the low tire pressure warning light
illuminates, you should stop and adjust the
tire pressure of all four tires to the recom-
mended COLD tire pressure shown on the
Tire and Loading Information label located
in the driver’s door opening. The low tire
pressure warning light does not automati-
cally turn off when the tire pressure is ad-
justed. After the tire is inflated to the rec-
ommended 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 low tire pressure warning light remains illu-
minated until the tires are inflated to the recom-
mended COLD tire pressure. The CHECK TIRE
PRES warning message is displayed each time
the ignition switch is placed in the ON position as
long as the low tire pressure warning light re-
mains illuminated.
