Malfunction Indicator Light
(MIL)
If the malfunction indicator light comes on
steady or blinks while the engine is
running, it may indicate a potential emis-
sion 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 US 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 ex-
ists.
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/main-
tenance test. (See
“Readiness for Inspec-
tion/Maintenance (I/M) test (US only)” (P.9-
22).)
Operation:
The malfunction indicator light will come
on in one of two ways:
. Malfunction indicator light on steady —
An emission control system malfunc-
tion has been detected. Check the fuel-
filler cap if the Loose Fuel Cap warning
appears in the vehicle information dis-
play. 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 an INFINITI retai-
ler. You do not need to have your
vehicle towed to the retailer.
. Malfunction indicator light blinking —An engine misfire has been detected
which may damage the emission con-
trol system.
To reduce or avoid emission control
system damage:
1) Do not drive at speeds above 45
MPH (72 km/h).
2) Avoid hard acceleration or decelera- tion.
3) Avoid steep uphill grades.
4) 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 an
INFINITI retailer. You do not need to
have your vehicle towed to the retailer.
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.

There is a small reserve of fuel remaining
in the tank when the fuel gauge reaches
the empty (0) position.

1. Engine oil and filter replacement
indicator
This indicator appears when the customer
set time comes for changing the engine oil
and filter. You can set or reset the distance
for changing the engine oil and filter.
2. Tire replacement indicator
This indicator appears when the customer
set distance comes for replacing tires. You
can set or reset the distance for replacing
tires.
WARNING
The tire replacement indicator is not a
substitute for regular tire checks, including
tire pressure checks. See“Changing wheels
and tires” (P.8-38). 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.
3. Other indicator
This indicator appears when the customer
set time comes for replacing items other
than the engine oil, oil filter and tires. You
can set or reset the distance for replacing
the items.
