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.

WARNING
When the daytime running light system is
active, tail lights on your vehicle are not on.
It is necessary at dusk to turn on your
headlights. Failure to do so could cause an
accident injuring yourself and others.
Adaptive Front lighting System
(AFS) (if so equipped)
The Adaptive Front lighting System (AFS)
will automatically adjust the headlights
(low beam) toward the turning direction to
improve the driver’s view. When the head-
light switch is ON and the driver operates
the steering wheel in a turn, the AFS
system will be activated.
The AFS will operate:
.when the headlight switch is ON.
. when the shift lever is in any position
other than P (Park) or R (Reverse).
. when the vehicle is driven at above 3
MPH (5 km/h) for the left-side head-
light. Note that the right-side low beam
headlight will swivel but the left-side
headlight will not swivel when the
vehicle is below 3 MPH (5 km/h) and the steering wheel is turned.
AFS will also adjust the headlight to a
proper axis automatically, depending on
the number of occupants in the vehicle, the
load the vehicle is carrying and the road
conditions.
If the AFS warning appears in the vehicle
information display after the ignition
switch has been pushed to the ON posi-
tion, this may indicate that the AFS is not
functioning properly. Have the system
checked by an INFINITI retailer. When the
engine is started, the headlights will
vibrate to check the system condition. This

FUEL-FILLER CAP
WARNING
. Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seriously
injured if it is misused or mishandled.
Always stop engine and do not smoke or
allow open flames or sparks near the
vehicle when refueling.
. Do not attempt to top off the fuel tank
after the fuel pump nozzle shuts off
automatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire.
. Use only an original equipment type
fuel-filler cap as a replacement. It has a
built-in safety valve needed for proper
operation of the fuel system and emis-
sion control system. An incorrect cap can result in a serious malfunction and
possible injury. It could also cause the
Malfunction Indicator Light (MIL) to
come on.
. Never pour fuel into the throttle body to
attempt to start your vehicle.
. Do not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable fuel
containers:
—Always place the container on the
ground when filling.
—Do not use electronic devices whenfilling.
—Keep the pump nozzle in contact
with the container while you are
filling it.
—Use only approved portable fuelcontainers for flammable liquid.
CAUTION
. If fuel is spilled on the vehicle body,
flush it away with water to avoid paint
damage.
. Insert the cap straight into the fuel-filler
tube, then tighten the fuel-filler cap until
a single click is heard. Failure to tighten
the fuel-filler cap properly may cause the
Malfunction Indicator Light (MIL) to
illuminate. If thelight illuminates
because 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 retailer.
. The Loose Fuel Cap warning will appear
if the fuel-filler cap is not properly
tightened. It may take a few driving
trips for the warning to be displayed.
Failure to tighten the fuel-filler cap
properly after the Loose Fuel Cap warn-
ing appears may cause the
Mal-
function Indicator Light (MIL) to
illuminate.
