WARNING
cYour 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.
cPressing 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.
cIf 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 at a
NISSAN dealer.
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, see a NISSAN
dealer immediately.
CAUTION
cDo not ground electrical accessories
directly to the battery terminal. Doing
so will bypass the variable control sys-
tem and the vehicle battery may not
charge completely. Refer to “Variable
voltage control system” in the “Mainte-
nance and do-it-yourself” section later
in this manual.
cDo not continue driving if the generator
belt is loose, broken or missing.

Low tire pressure warning
light
Your vehicle is equipped with a Tire Pressure
Monitoring System (TPMS) that monitors 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.
After 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 pres-
sure, the warning light will illuminate. If you select
the tire pressure information (if so equipped) in
the display, the LOW PRESSURE warning mes-
sage will be displayed. The tire pressure for each
tire will also be displayed.When the low tire pressure warning light illumi-
nates, you should stop and adjust the tire pres-
sure to the recommended COLD tire pressure
shown on the Tire and Loading Information label.
The low tire pressure warning light does not
automatically turn off when the tire pressure is
adjusted. After the tire is inflated to the recom-
mended 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.

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.
The malfunction indicator light may also come on
steady if the fuel-filler cap is loose or missing, or if
the vehicle runs out of fuel. Check to make sure
the fuel-filler cap is installed and closed tightly,
and that the vehicle has at least 3 gallons (11.4
liters) of fuel in the fuel tank.
After a few driving trips, the
light should
turn off if no other potential emission control
system malfunction exists.
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 sys-
tem inspection/maintenance test. See “Readi-
ness for inspection/maintenance (I/M) test” in the
“Technical and consumer information” section of
this manual.
Operation
The malfunction indicator light will come on in
one of two ways:
cMalfunction indicator light on steady — An
emission control system malfunction hasbeen detected. Check the fuel-filler cap. 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 after
a few driving trips. If thelight does not
turn off after a few driving trips, have the
vehicle inspected by a NISSAN dealer. You
do not need to have your vehicle towed to
the dealer.
cMalfunction indicator light blinking — An en-
gine misfire has been detected which may
damage the emission control system. To re-
duce or avoid emission control system dam-
age:
– 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 malfunction indicator light may stop blinking
and come on steady. Have the vehicle inspected
by a NISSAN dealer. You do not need to have
your vehicle towed to the dealer.
CAUTION
Continued vehicle operation without hav-
ing the emission control system checked
and repaired as necessary could lead to
poor driveability, reduced fuel economy,
and possible damage to the emission con-
trol system.
Security indicator light (if so
equipped)
This light blinks whenever the ignition switch is in
the LOCK, OFF or ACC position. This function
indicates the security system equipped on the
