• The power seat motor has an auto-resetoverload protection circuit. If the motor
stops during operation, wait 30 seconds
then reactivate the switch.
• Do not operate the power seat switch for a long period of time when the engine is
off. This will discharge the battery.

onds unless the driver's seat belt is se-
curely fastened.
The seat belt warning light may also illumi-
nate if the front passenger's seat belt is not
fastened when the front passenger's seat
is occupied. For 7 seconds af ter the ignition
switch is placed in the ON position, the sys-
tem does not activate the warning light for
the front passenger.
For additional information, refer to “Seat

stop the vehicle and move the shif t lever to
the N (Neutral) position with the brake
pedal depressed.
Turn signal/hazard
indicator lights
The appropriate light flashes when the turn
signal switch is activated.
NOTE:
In case of turn signal light bulb malfunc-
tion, the turn signal will flash at a higher
frequency when the turn signal switch is
activated.
Both lights flash when the hazard switch is
turned on.
Vehicle Dynamic Control
(VDC) OFF indicator light
This indicator light comes on when the
VDC OFF switch is pushed to the OFF posi-
tion, the transfer case is in the 4LO position
(
model), or when the VDC system is
not functioning properly. This indicates the
VDC system is not operating.
Push the VDC OFF switch again or restart
the engine and the system will operate normally. For additional information, refer
to “Vehicle Dynamic Control (VDC) system”
in the “Starting and driving” section of this
manual.
The VDC light also comes on when the
push-button ignition switch is in the ON
position. The light will turn off af ter about 2
seconds if the system is operational. If the
light stays on or comes on along with the
indicator light while you are driving,
have the VDC system checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
If the battery is removed or discharged, the
VDC system is disabled and the VDC indi-
cator light will not turn off af ter 2 seconds
when the ignition switch is placed in the ON
position. To reset the system, you must
perform the reset procedure. For addi-
tional information, refer to “Vehicle Dy-
namic Control (VDC) system” in the “Start-
ing and driving” section of this manual.
If the light does not go off af ter performing
the reset procedure, have the traction con-
trol system checked. It is recommended that
you visit a NISSAN dealer for this service.
While the VDC system is operating, you
might feel slight vibration or hear the sys-
tem working when starting the vehicle or
accelerating, but this is normal. The VDC system will be disabled and the
VDC light will illuminate when the elec-
tronic locking rear differential (E-lock) sys-
tem switch (if so equipped) is turned on
and the E-lock system is engaged. If the
E-lock system disengages or the switch is
turned off, the VDC system will be enabled

2-24Instruments and controls

Autolight system (if so equipped)
The autolight system allows the headlights
to be set so they turn on and off automati-
cally. The autolight system can:
• Turn on the headlights, front parking, tail,license plate and instrument panel lights
automatically when it is dark.
• Turn off all the lights when it is light.
• Keep all the lights on for a period of time af ter you place the ignition switch in the
OFF position and all doors are closed. To turn on the autolight system:
1. Turn the headlight switch to the AUTO
position
O1.
2. Place the ignition switch in the ON position.
3. The autolight system automatically turns the headlights on and off.
Initially, if the ignition switch is placed in the
OFF position and a door is opened and lef t
open, the headlights remain on for a period
of time. If another door is opened while the
headlights are on, then the timer is reset.
To turn the autolight system off, turn the
switch to the OFF,
,orposition.
The headlights will turn on automatically at
twilight or in rainy weather (when the wind-
shield wiper is operated continuously).
If the ignition switch is pushed to the OFF
position and one of the doors is opened
and this condition is continued, the head-
lights remain on for 5 minutes. Be sure you do not put anything on top
of the autolight sensor
O1located in the
top side of 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 switch in the
ON position, your vehicle's battery could
become discharged.

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 ve-
hicle's battery is discharged or is discon-
nected, HomeLink® will retain all pro-
gramming.
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 infor-
mation, refer to “Programming
HomeLink®” in this section.WARNING
• 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 unconscious-
ness or death.
• 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
detect an object in the path of a clos-
ing garage door and then automati-
cally stop and reverse, does not meet
current federal safety standards. Us-
ing 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.
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 (without starting the engine) when
programming HomeLink®. It is also rec-
ommended that a new battery be placed
in the hand-held transmitter of the de-
vice being programmed to HomeLink®
for quicker programming and accurate
transmission of the radio frequency.
