2-26Instruments and controls

Be sure you do not put anything on top
of the autolight sensor located in the top
side of the instrument panel. The auto-
light sensor controls the autolight; if it is
covered, the autolight sensor reacts as if
it is dark out and the headlights will illu-
minate. If this occurs while parked with
the engine off and the key in the ON po-
sition, your vehicle's battery could be-
come discharged.Headlight beam select
1To select the high beam function, rotate
the headlight stalk toposition and
then push the lever forward. The high
beam lights come on and the
light
illuminates.
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
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
automatically.
WARNING
• The High Beam Assist system is a
convenience 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
manually 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 vi-
cinity of the vehicle.

WARNING
• Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
• The Intelligent Key transmits radio
waves when the buttons are pressed.
The FAA advises the radio waves may
affect aircraf t navigation and com-
munication systems. Do not operate
the Intelligent Key while on an air-
plane. Make sure the buttons are not
operated unintentionally when the
unit is stored for a flight.
• Never leave the Intelligent Key in the
vehicle when you leave the vehicle.
The Intelligent Key system can operate all
the door locks using the remote control
function or pushing the request switch on
the vehicle without taking the key out from
a pocket or purse. The operating environ-
ment and/or conditions may affect the In-
telligent Key system operation.
Be sure to read the following before using
the Intelligent Key system.CAUTION
Be sure to carry the Intelligent Key with
you when operating the vehicle.
The Intelligent Key is capable of receiving
and transmitting radio waves. The Intelli-
gent Key system transmits weak radio
waves from various distances. Environ-
mental conditions may interfere with the
operation of the Intelligent Key system un-
der 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, trans-
ceiver, or a CB radio.
• When the Intelligent Key is in contact with or covered by metallic materials.
• When any type of radio wave remote con- trol 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 de-
pending on the operating conditions, the
battery’s life is approximately two years. If
the battery is discharged, replace it with a
new one.
When the Intelligent Key battery is low, a
yellow indicator illuminates with the mes-
sage “Key Battery Low” in the vehicle infor-
mation display. For additional information,
see “Vehicle information display warnings
and indicators” (P. 2-26).
Since the Intelligent Key is capable of re-
ceiving radio waves, if the key is lef t near
equipment which transmits strong radio
waves, such as signals from a TV and per-
sonal computer, the battery life may be-
come shorter.
For additional information, see “Battery re-
placement” (P. 8-21).
As many as four Intelligent Keys can be
registered and used with one vehicle. For
information about the purchase and use of
additional Intelligent Keys, it is recom-
mended that you visit a NISSAN dealer.

If all doors are already unlocked, opening
the trunk does NOT require an Intelligent
Key to be in range of the trunk request
switch or rear of the vehicle.
When the Intelligent Key battery is dis-
charged or strong radio waves are present
near the operating location, the Intelligent
Key operating range becomes narrower,
and the Intelligent Key may not function
properly.
The operating range is within 31.50 in (80
cm) from each request switch
O1.
If the Intelligent Key is too close to the door
glass, handle or rear bumper, the request
switches may not function.
When the Intelligent Key is within the oper-
ating range, it is possible for anyone, even
someone who does not carry the Intelli-
gent Key, to push the request switch to
lock/unlock the doors within range.
DOOR LOCKS/UNLOCKS

Intelligent Key button operation
light
The light blinks only when you press any
button on the Intelligent Key. The light illu-
mination only signifies that the key fob has
transmitted a signal. You may look and/or
listen to verif y that the vehicle has per-
formed the intended operation. The num-
ber of blinks identifies each registered key
(i.e. 1 blink = 1st key,...,4 blinks = 4th key) for
your own identification purposes. If the light does not blink, your battery may
be too weak to communicate to the ve-
hicle. If this occurs, the battery may need to
be replaced. For additional information re-
garding the replacement of a battery, see
“Battery replacement” (P. 8-21).
WARNING SIGNALS
To help prevent the vehicle from moving
unexpectedly by erroneous operation of
the Intelligent Key or to help prevent the
vehicle from being stolen, a chime or
buzzer sounds from inside and outside the
vehicle and a warning is displayed in the
instrument panel.
When a chime or beep sounds or a warning
is displayed, be sure to check the vehicle
and the Intelligent Key.
