After a few driving trips, thelight 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 Inspection/Mainte-
nance (I/M) test” (P.10-33).)
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 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. It is recommended you visit an
INFINITI retailer for this service. 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 control sys- tem.
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. It is recom-
mended you visit an INFINITI retailer for
this service. You do not need to have
your vehicle towed to the retailer.

Daytime running light system
The daytime running lights automatically
illuminate when the engine is started with
the parking brake released. The daytime
running lights operate with the headlight
switch in the OFF position or in the
position. Turn the headlight switch to theposition for full illumination when driv-
ing at night.
If the parking brake is applied before the
engine is started, the daytime running lights
do not illuminate. The daytime running lights
illuminate once the parking brake is released.
The daytime running lights will remain on
until the ignition switch is pushed to the OFF
position.
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 OFF indicator light blinks after
the ignition switch has been pushed to the
ON position, this may indicate that the AFS
is not functioning properly. Have the system
checked. It is recommended you visit an
INFINITI retailer for this service. When the
engine is started, the headlights will vibrate
to check the system condition. This is not a
malfunction.
HEADLIGHT WASHER (if so
equipped)

activates once each time either the ignition
switch or the headlight switch is turned off
and on.
After the first operation, the headlight
washer operates once at every fifth opera-
tion of the windshield washer.
CAUTION
. Do not operate the washer continu-
ously for longer than 30 seconds.
. Do not operate the headlight washer
if the window washer fluid reservoir
is empty.
