Malfunction Indicator Light (MIL)
If the malfunction indicator light comes on
steady or blinks while the engine is running, it
may indicate a potential emission control mal-
function.
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 US
gallons (14 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 remains on 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. (See “Readiness for Inspec-
tion/Maintenance (I/M) test” (P.9-23) .)

Operation:
The malfunction indicator light will come on in
one of two ways:
.Malfunction indicator light on steady — An
emission control system malfunction has
been detected. Check the fuel-filler cap if
the LOOSE FUEL CAP warning appears in
the vehicle information 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 after a few
driving trips. If the
light 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.
. Malfunction indicator light blinking — An
engine misfire has been detected which may
damage the emission 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 malfunction indicator light may stop
blinking and remain on. 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
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.
