3. Close all doors, hood and liftgate. Lock alldoors. The doors can be locked with the
Intelligent Key, door handle request
switch, or power door lock switch.
4. Confirm that the
security indicator
light stays on for about 30 seconds. The
vehicle security system is now pre-armed.
The vehicle security system will automati-
cally shift into the armed phase. The
security light begins to flash once every
three seconds. If during the pre-armed
phase one of the following occurs, the
system will not arm:
• Any door is unlocked with the Intelligent Key or door request switch.
• Ignition switch is placed in AUTO ACC or ON position.
• Even when the driver and/or passengers
are in the vehicle, the system will activate
with all the doors, hood and liftgate locked
with the ignition switch placed in the
LOCK position. When placing the ignition
switch in the AUTO ACC or ON position,
the system will be released.
Vehicle security system activation
The vehicle security system will give the fol-
lowing alarm:
• The turn signals blink and the horn sounds intermittently.
• The alarm automatically turns off after a period of time. However, the alarm reacti-
vates if the vehicle is tampered with again.
The alarm can be shut off by pressing the
button on the Intelligent Key.
The alarm is activated by:
• Opening the door or liftgate without using the Intelligent Key (even if the door is un-
locked by releasing the door inside lock
switch).
How to stop an activated alarm
The alarm stops only by unlocking the driver’s
door or the liftgate by pressing the
button on the Intelligent Key or pushing the
request switch on the driver's or passenger's
door with the Intelligent Key in range of the
door handle.
INFINITI VEHICLE IMMOBILIZER
SYSTEM
The INFINITI Vehicle Immobilizer System will
not allow the engine to start without the use
of a registered INFINITI Vehicle Immobilizer
System key.
If the engine fails to start using a registered
INFINITI Vehicle Immobilizer System key (for
example, when interference is caused by an-
other INFINITI Vehicle Immobilizer System
key, an automated toll road device or auto-
matic payment device on the key ring), restart
the engine using the following procedures:
1. Leave the ignition switch in the ON posi- tion for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the interfer-
ence) separate from the registered
INFINITI Vehicle Immobilizer System key.
If the no start condition re-occurs, INFINITI
recommends placing the registered INFINITI

Adaptive Front lighting System
(AFS) (if so equipped)
The Adaptive Front lighting System (AFS) will
automatically adjust the headlights (low
beam) toward the turning direction to im-
prove the driver’s view. When the headlight
switch is ON and the driver operates the
steering wheel in a turn, the AFS system will
be activated.
The AFS will operate:
• when the headlight switch is ON.
• when the shift lever is in any position otherthan P (Park) or R (Reverse).
• when the vehicle is driven at above 16 mph (25 km/h) for the left-side headlight. Note
that the right-side low beam headlight will
swivel but the left side will not swivel when
the vehicle is at a stop and the steering
wheel is turned. The vehicle must attain a
speed above 16 mph (25 km/h) before AFS
activates the left-side headlight.
AFS will also adjust the headlight to a proper
axis automatically, depending on the number
of occupants in the vehicle, the load the ve-
hicle is carrying and the road conditions. If the AFS OFF indicator blinks or the vehicle
information display shows an AFS system
error message after the ignition switch has
been pushed to the ON position, this may
indicate that the AFS is not functioning prop-
erly. Have the system checked. It is recom-
mended you visit an INFINITI retailer for this
service. When the engine is started, the head-
lights will vibrate to check the system condi-
tion. This is not a malfunction.
Automatic headlight aiming control
(if so equipped)
Your vehicle is equipped with an automatic
headlight levelling system. The headlight axis
is controlled automatically.
INFINITI recommends that you consult the
local regulations on the use of lights.
LED DAYTIME RUNNING LIGHTS
(DRL) SYSTEM
The LED portion of the headlights automati-
cally illuminate at 100% intensity when the
engine is started and the parking brake re-
leased. The LED Daytime Running Lights
(DRL) system operates with the headlight
switch in the OFF position. When you turn
the headlight switch to the
position for
full illumination, the LED lights switch from
LED DRL system to the park function. If the parking brake is applied before the
engine is started, the LED DRL system does
not illuminate. The LED DRL system illumi-
nates when the parking brake is released. The
LED DRL system will remain on until the
ignition switch is placed in the OFF position.
It is necessary at dusk to turn the headlight
switch on for interior controls and switches
to illuminate, as those remain off while the
switch is in the OFF position.
WARNING
When the LED DRL system is active, tail
lights on your vehicle are not on. It is nec-
essary at dusk to turn on your headlights.
Failure to do so could cause an accident
injuring yourself and others.

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 devicessuch 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 vehi-
cle's battery is discharged or is discon-
nected, HomeLink® will retain all
programming.
When the HomeLink® Universal Transceiver
is programmed, retain the original transmit-
ter for future programming procedures (Ex-
ample: new vehicle purchases). Upon sale of
the vehicle, the programmed HomeLink®
Universal Transceiver buttons should be
erased for security purposes. For additional
information, see “Programming HomeLink®”
(P. 2-70).
WARNING
• Your vehicle's engine should be turned
off while programming the HomeLink®
Universal Transceiver. For additional in-
formation, see “Push-button ignition
switch” (P. 5-13). Do not breathe ex-
haust gases; they contain colorless and
odorless carbon monoxide. Carbon mon-
oxide is dangerous. It can cause uncon-
sciousness or death.
•
Do not use the HomeLink® Universal
Transceiver with any garage door opener
that lacks safety stop and reverse features
as required by federal safety standards.
(These standards became effective for
opener models manufactured after April 1,
1982.) A garage 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 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 diffi-
culty programming your HomeLink® but-
tons, refer to the HomeLink® web site at:
www.homelink.com or call 1-800-355-3515.
NOTE:
Place the ignition switch in the ON position
(without starting the engine) when pro-
gramming HomeLink®. It is also recom-
mended that a new battery be placed in the
hand-held transmitter of the device being
programmed to HomeLink® for quicker pro-
gramming and accurate transmission of the
radio frequency.

3-38Pre-driving checks and adjustments

WARNING
• Do not leave children or adults who
would normally require the assistance of
others alone in your vehicle. Pets should
also not be left alone. They could acci-
dentally injure themselves or others
through inadvertent operation of the
vehicle. Also, on hot, sunny days, tem-
peratures in a closed vehicle could
quickly become high enough to cause se-
vere or possibly fatal injuries to people or
animals.
• Properly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or colli-
sion, unsecured cargo could cause per-
sonal injury.
EXHAUST GAS (carbon monoxide)
WARNING
• Do not breathe exhaust gases; they con-
tain colorless and odorless carbon mon-
oxide. Carbon monoxide is dangerous. It
can cause unconsciousness or death. •
If you suspect that exhaust fumes are
entering the vehicle, drive with all win-
dows fully open, and have the vehicle in-
spected immediately.
• Do not run the engine in closed spaces
such as a garage.
• Do not park the vehicle with the engine
running for any extended length of time.
• Keep the rear vent windows, liftgates,
doors and trunk lids (if so equipped)
closed while driving, otherwise exhaust
gases could be drawn into the passenger
compartment. If you must drive with one
of these open, follow these precautions:
1. Open all the windows.
2. Set the
air recirculation button
to off and the fan control dial to high
to circulate the air.
• If electrical wiring or other cable connec-
tions must pass to a trailer through the
seal on the liftgate or the body, follow
the manufacturer's recommendation to
prevent carbon monoxide entry into the
vehicle.
• The exhaust system and body should be
inspected by a qualified mechanic when-
ever:
a. The vehicle is raised for service. b. You suspect that exhaust fumes are
entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involving damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Ex-
haust gases in the three-way catalyst are
burned at high temperatures to help reduce
pollutants.
WARNING
• The exhaust gas and the exhaust system
are very hot. Keep people, animals or
flammable materials away from the ex-
haust system components.
• Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite and
cause a fire.
PRECAUTIONS WHEN STARTING
AND DRIVING
5-4Starting and driving

CAUTION
• Do not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst's ability to
help reduce exhaust pollutants.
• Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause over rich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if noticeable
loss of performance or other unusual op-
erating conditions are detected. Have
the vehicle inspected promptly. It is rec-
ommended that you visit an INFINITI re-
tailer for this service.
• Avoid driving with an extremely low fuel
level. Running out of fuel could cause the
engine to misfire, damaging the three-
way catalyst.
• Do not race the engine while warming it
up.
• Do not push or tow your vehicle to start
the engine.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label.
(If your vehicle has tires of a different size
than the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.)
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitor-
ing System (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check all your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability. Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the
system detects a malfunction, the telltale will
flash for approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illumi-
nated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea-
sons, including the installation of replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion telltale after replacing one or more tires
or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels al-
low the TPMS to continue to function
properly.
