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)
The headlight washer operates when the
headlight is on and the ignition switch is in
the ON position.
Pull the windshield washer switch toward
you. The headlight washer operates with the
windshield washer operation. This operation
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.

engine start function. This function allows
the engine to start from outside the vehicle.
Some systems, such as the air conditioner
system, will turn on during a remote engine
start, if the system was on the last time the
ignition switch was turned off.
Laws in some local communities may restrict
the use of remote engine starters. For
example, some laws require a person using
remote engine start to have the vehicle in
view. Check local regulations for any re-
quirements.
Other conditions may affect the remote
engine start function. See “Conditions the remote engine start will not work” (P.3-20).
Other conditions can affect the performance
of the Intelligent Key transmitter. See “In-
telligent Key system” (P.3-7) for additional
information.
