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 otherthan P (Park) or R (Reverse).
• when the vehicle is driven at above 16 mph (25 km/h) for the left-side headlight. 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 vehicle 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.
Automatic headlight aiming control
(if so equipped)
Your vehicle is equipped with an automatic
headlight levelling system. The headlight axis
is controlled automatically.
INFINITI recommends that you consult the
local regulations on the use of lights.
LED DAYTIME RUNNING LIGHTS
(DRL) SYSTEM
The LED portion of the headlights automati-
cally illuminate at 100% intensity when the
engine is started and the parking brake re-
leased. The LED Daytime Running Lights
(DRL) system operates with the headlight
switch in the OFF position. When you turn
the headlight switch to the
position for
full illumination, the LED lights switch from
LED DRL system to the park function. If the parking brake is applied before the
engine is started, the LED DRL system does
not illuminate. The LED DRL system illumi-
nates when the parking brake is released. The
LED DRL system will remain on until the
ignition switch is placed in the OFF position.
It is necessary at dusk to turn the headlight
switch on for interior controls and switches
to illuminate, as those remain off while the
switch is in the OFF position.
WARNING
When the LED DRL system is active, tail
lights on your vehicle are not on. It is nec-
essary at dusk to turn on your headlights.
Failure to do so could cause an accident
injuring yourself and others.
