Seat belt warning light and
chime
The light and chime remind you to fasten your
seat belts. The light illuminates whenever the
ignition key is turned to the ON or START position
and remains illuminated until the driver’s seat belt
is fastened. At the same time, the chime sounds
for about 7 seconds unless the driver’s seat belt
is securely fastened.
Refer to “Seat belts” in the “Seats, restraints and
supplemental air bag systems” section for pre-
cautions on seat belt usage.
Supplemental air bag warning
light
When the ignition key is in the ON or START
position, the supplemental air bag warning light
illuminates for about 7 seconds and then turns
off. This means the system is operational.
If any of the following conditions occur, the
supplemental front air bag, supplemental side air
bag (if so equipped) , curtain side-impact airbags, and pre-tensioner seat belt systems need
servicing and your vehicle must be taken to a
NISSAN dealer:
cThe supplemental air bag warning light re-
mains on after approximately 7 seconds.
cThe supplemental air bag warning light
flashes intermittently.
cThe supplemental air bag warning light does
not come on at all.
Unless checked and repaired, the supplemental
restraint system (air bag system) and/or the pre-
tensioner seat belts may not function properly.
For additional details see “Supplemental restraint
system” in the “Seats, restraints and supplemen-
tal air bag systems” section of this manual.
WARNING
If the supplemental air bag warning light
is on, it could mean that the supplemental
front air bag, supplemental side air bag,
curtain side-impact air bag systems (if so
equipped) and/or pre-tensioner seat belt
systems will not operate in an accident.
Trunk lid open warning light
This light comes on when the trunk lid is not
securely closed while the ignition key is in the ON
position.
INDICATOR LIGHTS
Cruise main switch indicator
light (if so equipped)
The light comes on when the cruise control main
switch is pushed. The light goes out when the
main switch is pushed again. When the cruise
main switch indicator light comes on, the cruise
control system is operational.
Cruise set switch indicator
light (if so equipped)
The light comes on while the vehicle speed is
controlled by the cruise control system. If the light
blinks while the engine is running, it may indicate
the cruise control system is not functioning prop-
erly. Have the system checked by a NISSAN
dealer.
High beam indicator light
(Blue)
This blue light comes on when the headlight high
beams are on and goes out when the low beams

vehicle is in motion, whether or not the brake
pedal is depressed. Have the brakes checked as
soon as possible if the warning sound is heard.

while the key is left in the ignition switch. Remove
the key and take it with you when leaving the
vehicle.

If the engine fails to start using a registered NVIS
key (for example, when interference is caused by
another NVIS key, an automated toll road device
or automatic payment device on the key ring) ,
restart the engine using the following proce-
dures:
1. Leave the ignition switch in the ON position
for approximately 5 seconds.
2. Turn the ignition switch to the OFF or LOCK
position, and wait approximately 5 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device
(which may have caused the interference)
separate from the registered NVIS key.
If the no start condition re-occurs, NISSAN rec-
ommends placing the registered NVIS key on a
separate key ring to avoid interference from other
devices.

3. Close the trunk lid and all doors. Lock all
doors. The doors can be locked with the key,
power door lock switch or with the keyfob.
Keyfob operation:
cPush the
button on the keyfob.
All doors lock. The hazard lights flash
twice and the horn beeps once to indicate
all doors are locked.
cWhen the
button is pushed with
all doors locked, the hazard lights flash
twice and the horn beeps once as a re-
minder that the doors are already locked.
The horn may or may not beep. Refer to
“Silencing the horn beep feature” later in this
section.
4. Confirm that the SECURITY indicator light
comes on. The SECURITY light stays on for
about 30 seconds. The vehicle security sys-
tem is now pre-armed. After about 30 sec-
onds the vehicle security system automati-
cally shifts into the armed phase. The
SECURITY light begins to flash once every 3
seconds. If, during the 30-second pre-arm
time period, the door is unlocked by the key
or the keyfob, or the ignition key is turned to
ACC or ON, the system will not arm.cIf the key is turned slowly when locking
the door, the system may not arm. Fur-
thermore, if the key is turned beyond
the vertical position toward the unlock
position to remove the key, the system
may be disarmed when the key is re-
moved. If the indicator light fails to
glow for 30 seconds, unlock the door
once and lock it again.
cEven when the driver and/or passen-
gers are in the vehicle, the system will
arm with all doors and trunk lid closed
and locked with the ignition key in the
OFF position.
Vehicle security system activation
The vehicle security system will give the following
alarm:
cThe headlights blink and the horn sounds
intermittently.
cThe alarm automatically turns off after ap-
proximately 1 minute. However, the alarm
reactivates if the vehicle is tampered with
again. The alarm can be shut off by unlocking
a door or trunk lid with the key, or by pressing
the
button on the keyfob.The alarm is activated by:
copening the door or trunk lid without using
the key or keyfob (even if the door is un-
locked by releasing the door inside lock
switch) or opening the trunk lid by operating
the opener lever.
How to stop an activated alarm
The alarm stops only by unlocking a door or the
trunk lid with the key, or by pressing the
button on the keyfob.

The cargo net helps keep packages in the cargo
area from moving around while the vehicle is in
motion.
To install the cargo net, attach the hooks to the
retainers.
To remove the cargo net, detach the hooks from
the cargo net retainers.
WARNING
cProperly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. In a sudden stop or collision,
unsecured cargo could cause personal
injury.

The interior lights illuminate when a front or rear
door is opened. Once the doors are closed,
these lights turn off in 30 seconds or turn off
immediately when the key is turned to the ON
position.
BATTERY SAVER
If the vehicle doors are not fully closed and the
interior lights remain illuminated, they eventually
turn off automatically to prevent the battery from
becoming discharged. Interior lights that illumi-
nate when doors are opened turn off after ap-
proximately 30 minutes.The HomeLinkTUniversal Transceiver provides a
convenient way to consolidate the functions of up
to three individual hand-held transmitters into
one built-in device.
HomeLinkTUniversal Transceiver:
cWill operate most Radio Frequency (RF)
devices such as garage doors, gates, home
and office lighting, entry door locks and se-
curity systems.
cIs powered by your vehicle’s battery. No
separate batteries are required. If the vehi-
cle’s battery is discharged or is discon-
nected, HomeLinkTwill retain all program-
ming.
Once the HomeLinkTUniversal Transceiver
is programmed, retain the original trans-
mitter for future programming procedures
(i.e., new vehicle purchases) . Upon sale of
the vehicle, the programmed HomeLinkT
Universal Transceiver buttons should be
erased for security purposes. For addi-
tional information refer to “Programming
the HomeLinkTUniversal Transceiver” later
in this section.
WARNING
cDo not use the HomeLinkTUniversal
Transceiver with any garage door
opener that lacks safety stop and re-
verse features as required by federal
safety standards. (These standards be-
came effective for opener models
manufactured after April 1, 1982) . A ga-
rage door opener which cannot detect
an object in the path of a closing garage
door and then automatically stop and
reverse, does not meet current federal
safety standards. Using a garage door
opener without these features in-
creases the risk of serious injury or
death.
cDuring 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.
cYour vehicle’s engine should be turned
off while programming the HomeLinkT
Universal Transceiver.
