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 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

CAUTION
.Be sure to carry the Intelligent Key
with you when operating the vehicle.
. Never leave the Intelligent Key in the
vehicle when you leave the vehicle.
The Intelligent Key is always communicating
with the vehicle as it receives radio waves.
The Intelligent Key system transmits weak
radio waves. Environmental conditions may
interfere with the operation of the Intelligent
Key system under the following operating
conditions.
. When operating near a location where
strong radio waves are transmitted, such
as a TV tower, power station and broad-
casting station.
. When in possession of wireless equip-
ment, such as a cellular telephone,
transceiver, and CB radio.
. When the Intelligent Key is in contact
with or covered by metallic materials.
. When any type of radio wave remote
control is used nearby.
. When the Intelligent Key is placed near
an electric appliance such as a personal
computer. .
When the vehicle is parked near a parking
meter.
In such cases, correct the operating condi-
tions before using the Intelligent Key func-
tion or use the mechanical key.
Although the life of the battery varies
depending on the operating conditions, the
battery’s life is approximately 2 years. If the
battery is discharged, replace it with a new
one.
When the Intelligent Key battery is almost
discharged, see “Intelligent Key battery dis-
charge” (P.5-14) to start the engine.
Since the Intelligent Key is continuously
receiving radio waves, if the key is left near
equipment which transmits strong radio
waves, such as signals from a TV and
personal computer, the battery life may
become shorter.
For information regarding replacement of a
battery, see “Intelligent Key battery replace-
ment” (P.8-19).
As many as 4 Intelligent Keys can be
registered and used with one vehicle. For
information about the purchase and use of
additional Intelligent Keys, contact an
INFINITI retailer.
CAUTION
. Do not allow the Intelligent Key,
which contains electrical compo-
nents, to come into contact with
water or salt water. This could affect
the system function.
. Do not drop the Intelligent Key.
. Do not strike the Intelligent Key
sharply against another object.
. Do not change or modify the Intelli-
gent Key.
. Wetting may damage the Intelligent
Key. If the Intelligent Key gets wet,
immediately wipe until it is comple-
tely dry.
. Do not place the Intelligent Key for
an extended period in an area where
temperatures exceed 140°F (60°C).
. If the outside temperature is below
14°F (−10°C), the battery of the
Intelligent Key may not function
properly.
. Do not attach the Intelligent Key
with a key holder that contains a
magnet.
. Do not place the Intelligent Key near
equipment that produces a magnetic
field, such as a TV, audio equipment
