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 ap-
plied, stop the vehicle and perform the
following:
1. Check the brake fluid level. Add brakefluid as necessary. For additional infor-
mation, see “Brake fluid” (P. 8-15).
2. If the brake fluid level is correct, have the warning system checked. It is recom-
mended 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 re-
pairs. 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 stop-
ping distance and braking will re-
quire 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.
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. Do-
ing so will bypass the variable volt-
age control system (if so equipped)
and the vehicle battery may not
charge completely. For additional in-
formation, see “Variable voltage con-
trol system” (P. 8-20).
• Do not continue driving if the genera-
tor belt is loose, broken or missing.
Electric shif t control system

warning light
This light warns of low engine oil pressure. If
the light flickers or comes on during nor-
mal driving, pull off the road in a safe area,
stop the engineimmediately,and call a
NISSAN dealer or other authorized repair
shop.
The engine oil pressure warning light is
not designed to indicate a low oil level.
Use the dipstick to check the oil level. For
additional information, see “Engine oil”
(P. 8-8).

Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not cov-
ered by warranty. Turn off the engine as
soon as it is safe to do so.
Malfunction Indicator Light
(MIL)
If this indicator light comes on steady or
blinks while the engine is running, it may
indicate a potential emission control
malfunction. If this indicator light comes on steady for 20
seconds and then blinks for 10 seconds
when the engine is not running, it indicates
that the vehicle is not ready for an emission
control system inspection/maintenance
test. For additional information, see “Readi-
ness for inspection/maintenance (I/M)
test” (P. 10-57).
Operation
The MIL will come on in one of two ways:
• MIL on steady — An emission control sys-
tem malfunction has been detected.
Check the fuel-filler cap if the Loose Fuel
Cap warning appears in the vehicle infor-
mation display. If the fuel-filler cap is loose
or missing, tighten or install the cap and
continue to drive the vehicle. The
light should turn off af ter a few driving
trips. If thelight does not turn off
af ter a few driving trips, have the vehicle
inspected. It is recommended that you
visit a NISSAN dealer for this service. You
do not need to have your vehicle towed
to the dealer.
• MIL blinking — An engine misfire has been detected which may damage the emis-
sion control system. To reduce or avoid
emission control system damage:– do not drive at speeds above 45 mph (72 km/h). – avoid hard acceleration or
deceleration.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo being hauled or towed.
The MIL may stop blinking and come on
steady. Have the vehicle inspected. It is rec-
ommended that you visit a NISSAN dealer
for this service. You do not need to have
your vehicle towed to the dealer.
CAUTION
Continued vehicle operation without
having the emission control system
checked and repaired as necessary
could lead to poor driveability, reduced
fuel economy, and possible damage to
the emission control system.

Maintenance
The maintenance menu allows the user to set reminders for various vehicle maintenance items.
Some menu items shown below may not be equipped on your vehicle.
WARNING
The tire replacement indicator is not a substitute for regular tire checks, including tire pressure checks. For additional informa-
tion, see “Changing wheels and tires” (P. 8-44). Many factors including tire inflation, alignment, driving habits and road conditions
affect tire wear and when tires should be replaced. Setting the tire replacement indicator for a certain driving distance does not
mean your tires will last that long. Use the tire replacement indicator as a guide only and always perform regular tire checks.
Failure to perform regular tire checks, including tire pressure checks could result in tire failure. Serious vehicle damage could
occur and may lead to a collision, which could result in serious personal injury or death.
