the vehicle, but the steering will be
much harder to operate. Have the
power steering system checked by a
NISSAN dealer.
When the ignition switch is in the ON position,
the power steering warning light illuminates. After
starting the engine, the power steering warning light turns off. This indicates that the electric
power steering system is operational. If the
power steering warning light illuminates while the
engine is running, it may indicate the power
steering system is not functioning properly and
may need servicing. Have the hydraulic pump
electric power steering system checked by a
NISSAN dealer. See “Power steering system” in
the “Starting and driving” section.
Seat belt warning light and
chime

After a few driving trips, thelight should
turn off if no other potential emission control
system malfunction exists.
If this indicator light comes on steady for 20 sec-
onds and then blinks for 10 seconds when the
engine is not running, it indicates that the vehicle
is not ready for an emission control system
inspection/maintenance test. See “Readiness for
inspection/maintenance (I/M) test” in the “Tech-
nical and consumer information” section of this
manual.
Operation
The Malfunction Indicator Light will come on in
one of two ways:
● Malfunction Indicator Light on steady — An
emission control system malfunction has
been detected. Check the fuel-filler cap if
the LOOSE FUEL CAP warning appears in
the vehicle information display. If the fuel-
filler cap is loose or missing, tighten or install
the cap and continue to drive the vehicle.
The
light should turn off after a few
driving trips. If the
light does not turn
off after a few driving trips, have the vehicle
inspected by a NISSAN dealer. You do not
need to have your vehicle towed to the
dealer. ●
Malfunction Indicator Light blinking — An
engine misfire has been detected which may
damage the emission control system. To re-
duce or avoid emission control system dam-
age:
– do not drive at speeds above 45 MPH (72 km/h).
– avoid hard acceleration or deceleration.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo being hauled or towed.
The Malfunction Indicator Light may stop blinking
and come on steady. Have the vehicle inspected
by a NISSAN dealer. You do not need to have
your vehicle towed to the dealer.
CAUTION
Continued vehicle operation without hav-
ing the emission control system checked
and repaired as necessary could lead to
poor driveability, reduced fuel economy,
and possible damage to the emission con-
trol system.

Instruments and controls2-15

Your vehicle may has two types of security sys-
tems:● Vehicle security system
● NISSAN Vehicle Immobilizer System
VEHICLE SECURITY SYSTEM
The vehicle security system provides visual and
audible alarm signals if someone opens the
doors, trunk lid or the hood when the system is
armed. It is not, however, a motion detection type
system that activates when a vehicle is moved or
when a vibration occurs.
The system helps deter vehicle theft but cannot
prevent it, nor can it prevent the theft of interior or exterior vehicle components in all situations. Al-
ways secure your vehicle even if parking for a
brief period. Never leave your Intelligent Key in
the vehicle, and always lock the vehicle when
unattended. Be aware of your surroundings, and
park in secure, well-lit areas whenever possible.
Many devices offering additional protection, such
as component locks, identification markers, and
tracking systems, are available at auto supply
stores and specialty shops. Your NISSAN dealer
may also offer such equipment. Check with your
insurance company to see if you may be eligible
for discounts for various theft protection features.
How to arm the vehicle security
system
1. Close all windows.
(The system can be
armed even if the windows are open.)
2. Remove the Intelligent Key from the vehicle.
3. Close all doors, hood and trunk/liftgate. Lock all doors. The doors can be locked with
the Intelligent Key, door handle request
switch (if so equipped) , power door lock
switch or mechanical key.
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 driver’s door is unlocked by
the key or the keyfob, or the ignition switch is
placed in the ACC or ON position, the sys-
tem will not arm.
● Even when the driver and/or passen-
gers are in the vehicle, the system will
activate with all the doors, hood and
trunk lid locked with the ignition
switch placed in the LOCK position.
When placing the ignition switch in the
ACC or ON position, the system will be
released.Vehicle security system activation
The vehicle security system will give the following
alarm:
● The headlights blink and the horn sounds
intermittently.
● The alarm automatically turns off after a pe-
riod of time. However, the alarm reactivates if
the vehicle is tampered with again. The alarm
can be shut off by unlocking the driver’s door
or trunk lid with the key, or by pressing
the
button on the Intelligent Key.

The HomeLink® Universal Transceiver provides
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 (RF)
devices such as garage doors, gates, home
and office lighting, entry door locks and se-
curity systems.
● Is powered by your vehicle’s battery. No
separate batteries are required. If the vehi-
cle’s battery is discharged or is discon-
nected, HomeLink® will retain all program-
ming.
When the HomeLink® Universal Trans-
ceiver is programmed, retain the original
transmitter for future programming proce-
dures (Example: new vehicle purchases) .
Upon sale of the vehicle, the programmed
HomeLink® Universal Transceiver buttons
should be erased for security purposes. For
additional information, refer to “Program-
ming HomeLink®” later 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 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.
● 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.
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 ACC posi-
tion when programming HomeLink®. It is
also recommended that a new battery be
placed in the hand-held transmitter of the
device being programmed to HomeLink®
for quicker programming and accurate
transmission of the radio-frequency.
1. Position the end of your hand-held transmit- ter 1–3 inches (2–8 cm) away from the
HomeLink® surface, keeping the
HomeLink® indicator light
1in view. 2. Using both hands, simultaneously press and
hold the desired HomeLink® button and
handheld transmitter button. DO NOT re-
lease until the HomeLink® indicator light1
flashes slowly and then rapidly. When the
indicator light flashes rapidly, both buttons
may be released. (The rapid flashing indi-
cates successful programming.)
NOTE:
Some devices may require you to replace
Step 2 with the cycling procedure noted in
the “Programing HomeLink® for Canadian
customers and gate openers” section.
