High Beam Assist indicatorlight (green)
This indicator light illuminates when the
headlights come on while the headlight
switch is in the AUTO position with the high
beams selected. This indicates that the high
beam assist is operational.
For additional information, refer to “Head-
light switch” in this section.
High beam indicator light(blue)
This blue light comes on when the headlight
high beams are on and goes out when the
low beams are selected.
The high beam indicator light also comes on
when the passing signal is activated.
Malfunction Indicator Light(MIL)
If this indicator light comes on steady or
blinks while the engine is running, it may indi-
cate a potential emission control malfunc-
tion. The MIL 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 gal-
lons (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 system inspection/maintenance test.
For additional information, refer to “Readi-
ness for Inspection/Maintenance (I/M) test”
in the “Technical and consumer information”
section of this manual. Operation
The MIL will come on in one of two ways:
∙ MIL on steady — An emission control sys- tem malfunction has been detected.
Check the fuel-filler cap if the Loose Fuel
Cap warning appears in the vehicle infor-
mation 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. It is recommended
that you visit an INFINITI retailer for this
service. You do not need to have your
vehicle towed to the retailer.
∙ MIL blinking — An engine misfire has been detected which may damage the emis-
sion 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 decelera- tion.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo being hauled or towed.

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 im-
prove the driver’s view. When the headlight
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 16 mph (25 km/h) for the left-side head-
light. Note that the right-side low beam
headlight will swivel but the left side will
not swivel when the vehicle is at a stop
and the steering wheel is turned. The ve-
hicle must attain a speed above 16 mph
(25 km/h) before AFS activates the left-
side headlight.
AFS will also adjust the headlight to a proper
axis automatically, depending on the number
of occupants in the vehicle, the load the ve-
hicle is carrying and the road conditions. If the AFS OFF indicator blinks or the vehicle
information display shows an AFS system
error message after the ignition switch has
been pushed to the ON position, this may
indicate that the AFS is not functioning prop-
erly. Have the system checked. It is recom-
mended you visit an INFINITI retailer for this
service. When the engine is started, the head-
lights will vibrate to check the system condi-
tion. This is not a malfunction.
