Be sure you do not put anything on top
of the autolight sensor located in the top
side
1of the instrument panel. The au-
tolight sensor controls the autolight; if it
is covered, the autolight sensor reacts as
if it is dark out and the headlights will
illuminate. If this occurs while parked
with the engine off and the ignition
switch placed in the ON position, your
vehicle’s battery could become dis-
charged.
Headlight beam select
1To select the high beam function, push
the lever forward. The high beam lights
come on and the
light illumi-
nates in the meter.
2Pull the lever back to select the low
beam.
3Pulling and releasing the lever flashes
the headlight high beams on and off.
High Beam Assist (if so equipped)
The High Beam Assist system will operate
when the vehicle is driven at speeds of ap-
proximately 25 mph (40 km/h) and above. If
an oncoming vehicle or leading vehicle ap-
pears in front of your vehicle when the
headlight high beam is on, the headlight
will be switched to the low beam automati-
cally.
WARNING
∙ The High Beam Assist system is a con- venience but it is not a substitute for
safe driving operation. The driver
should remain alert at all times, en-
sure safe driving practices and switch
the high beams and low beam manu-
ally when necessary.
∙ The high beam or low beam may not switch automatically under the fol-
lowing conditions. Switch the high
beam and low beam manually.
– During bad weather (rain, fog, snow, wind, etc.).
– When a light source similar to a headlight or tail light is in the vicin-
ity of the vehicle.

When the vehicle speed lowers to less than
approximately 16 mph (25 km/h), the head-
light uses the low beam.

tion or select the low beam position by
placing the lever in the neutral position.
Ambient image sensor maintenance
The ambient image sensor
1for the High
Beam Assist system is located in front of
the inside mirror. To maintain the proper
operation of the high beam assist system
and prevent a system malfunction, be sure
to observe the following:
∙ Always keep the windshield clean.
∙ Do not attach a sticker (including trans- parent material) or install an accessory
near the ambient image sensor. ∙ Do not strike or damage the areas
around the ambient image sensor. Do
not touch the sensor lens that is lo-
cated on the ambient image sensor.
If the ambient image sensor is damaged
due to an accident, it is recommended that
you visit a NISSAN dealer.

The HomeLink® Universal Transceiver pro-
vides a convenient way to consolidate the
functions of up to three individual hand-
held transmitters into one built-in device.
HomeLink® Universal Transceiver:∙ Will operate most radio frequency de- vices such as garage doors, gates,
home and office lighting, entry door
locks and security systems.
∙ Is powered by your vehicle’s battery. No separate batteries are required. If the
vehicle’s battery is discharged or is dis-
connected, HomeLink® will retain all
programming.
When the HomeLink® Universal Trans-
ceiver is programmed, retain the original
transmitter for future programming pro-
cedures (Example: new vehicle pur-
chases). Upon sale of the vehicle, the
programmed HomeLink® Universal
Transceiver buttons should be erased
for security purposes. For additional
information, refer to “Programming
HomeLink®” in this section.WARNING
∙ Do not use the HomeLink® Universal Transceiver with any garage door
opener that lacks safety stop and re-
verse features as required by federal
safety standards. (These standards
became effective for opener models
manufactured af ter April 1, 1982). A
garage door opener which cannot de-
tect an object in the path of a closing
garage door and then automatically
stop and reverse, does not meet cur-
rent federal safety standards. Using a
garage door opener without these
features increases the risk of serious
injury or death.
∙ During the programming procedure your garage door or security gate will
open and close (if the transmitter is
within range). Make sure that people
or objects are clear of the garage door,
gate, etc. that you are programming. ∙ Your vehicle’s engine should be
turned off while programming the
HomeLink® Universal Transceiver. Do
not breathe exhaust gases; they con-
tain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconsciousness
or death.
PROGRAMMING HOMELINK®
If you have any questions or are having
difficulty programming your HomeLink®
buttons, refer to the HomeLink® web site at:
www.homelink.com or call 1-800-355-3515.
NOTE:
Place the ignition switch in the ON posi-
tion (if so equipped) when programming
HomeLink®. It is also recommended that
a new battery be placed in the hand-held
transmitter of the device being pro-
grammed to HomeLink® for quicker pro-
gramming and accurate transmission of
the radio frequency.
