orBrake warning light
This light functions for both the parking brake and
the foot brake systems.
When the ignition key is in the ON position, the
light comes on when the parking brake is applied,
and also 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 vehicle
and perform the following:
1. Check the brake fluid level. Add brake fluid
as necessary. See “Brake and clutch fluid” in
the “Maintenance and do-it-yourself” sec-
tion of this manual.
2. If the brake fluid level is correct, have the
brake system checked by a NISSAN dealer.
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

dealer immediately.
CAUTION

dipstick to check the oil level.See “Engine
oil” in the “Maintenance and do-it-yourself” sec-
tion of this manual.
CAUTION

pressure warning light on could cause se-
rious damage to the engine almost imme-
diately. Such damage is not covered by
warranty. Turn off the engine as soon as it
is safe to do so.

tank is getting low. Refuel as soon as it is conve-
nient, preferably before the fuel gauge reaches E

tensioner seat belts may not function properly.
For additional details see “Supplemental restraint
system” in the “Seats, restraints and supplemen-
tal air bag systems” section of this manual.
WARNING
If the supplemental air bag warning light
is on, it could mean that the supplemental
front air bag, supplemental side air bag,
curtain side-impact air bag systems (if so
equipped) and/or pre-tensioner seat belt
systems will not operate in an accident.

Malfunction indicator lamp
(MIL)
If this indicator lamp comes on steady or blinks
while the engine is running, it may indicate a
potential emission control malfunction.
The malfunction indicator lamp 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 of fuel
in the fuel tank.
After a few driving trips, the
lamp should
turn off if no other potential emission control
system malfunction exists.
Operation
The malfunction indicator lamp will come on in
one of two ways:
cMalfunction indicator lamp on steady — An
emission control system malfunction has
been 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
lamp should turn off after
a few driving trips. If thelamp does
not turn off after a few driving trips, have the
vehicle inspected by a NISSAN dealer. Youdo not need to have your vehicle towed to
the dealer.
cMalfunction indicator lamp blinking — An
engine 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 lamp 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.
Slip indicator light (if so
equipped)
This indicator light will blink when the traction
control system is limiting wheel spin. Slippery
road conditions may exist if the slip indicator
blinks on. If this happens, adjust your driving
accordingly.
The slip indicator light also comes on when you
turn the ignition key to the ON position. The light
will turn off after about 2 seconds if the system is
operational. If the light does not come on or go
off, have the traction control system checked by a
NISSAN dealer.
The system operates in all transmission shift lever
positions, but the system can upshift the trans-
mission only as high as the indicated shift lever
position.
Traction control system off
indicator light
After turning the ignition key to the ON position,
the light will illuminate. The light will turn off after
about 2 seconds if the traction control system
(TCS) is operational.
If the light stays on or comes on when you are
driving, it may indicate the traction control system
is not functioning properly. Have the system
checked by a NISSAN dealer.

makes a high pitched scraping sound when the
vehicle is in motion, whether or not the brake
pedal is depressed. Have the brakes checked as
soon as possible if the warning sound is heard.
Key reminder chime
A chime sounds if the driver’s door is opened
while the key is left in the ignition switch. Remove
the key and take it with you when leaving the
vehicle.

If the engine fails to start using a registered NVIS
key (for example, when interference is caused by
another NVIS key, an automated toll road device
or automatic payment device on the key ring) ,
restart the engine using the following proce-
dures:
1. Leave the ignition switch in the ON position
for approximately 5 seconds.
2. Turn the ignition switch to the OFF or LOCK
position, and wait approximately 5 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device
(which may have caused the interference)
separate from the registered NVIS key.
If the no start condition re-occurs, NISSAN rec-
ommends placing the registered NVIS key on a
separate key ring to avoid interference from other
devices.
