Vehicle ahead detection
indicator
This indicator shows when the following sys-
tems (if so equipped) are engaged and have
detected a vehicle:
• Distance Control Assist (DCA)
• Forward Emergency Braking (FEB) withPedestrian Detection
• Predictive Forward Collision Warning (PFCW)
For additional information, see “Distance
Control Assist (DCA)” (P. 5-106), “Forward
Emergency Braking (FEB) with Pedestrian
Detection” (P. 5-123) or “Predictive Forward
Collision Warning (PFCW)” (P. 5-133) Your vehicle has two types of security
systems:
• Vehicle security system
• INFINITI Vehicle Immobilizer System
VEHICLE SECURITY SYSTEM
The vehicle security system provides visual
and audible alarm signals if someone opens
the doors, liftgate or 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 can-
not prevent it nor can it prevent the theft of
interior or exterior vehicle components in all
situations. Always 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. An
INFINITI retailer may also offer such equip-
ment. 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 and the moonroof (if so
equipped). (The system can be armed even
if the windows and moonroof are open.)
2. Remove the Intelligent Key from the vehicle.
LIC0661
SECURITY SYSTEMS
Instruments and controls2-29

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
2-30Instruments and controls

Vehicle Immobilizer System key on a separate
key ring to avoid interference from other
devices.

INFINITI INTELLIGENT KEY
Your vehicle can only be driven with the Intel-
ligent Keys which are registered to your vehi-
cle’s Intelligent Key System components and
INFINITI Vehicle Immobilizer System
components.Never leave the keys in the vehicle.
As many as four Intelligent Keys can be reg-
istered and used with one vehicle. The new
keys must be registered prior to use with the
Intelligent Key System and INFINITI Vehicle
Immobilizer System of your vehicle. It is rec-
ommended that you visit an INFINITI retailer
for this service. Since the registration process
requires erasing all memory in the Intelligent
Key components when registering new keys,
be sure to take all Intelligent Keys that you
have to an INFINITI retailer.A key number plate is supplied with your keys.
Record the key number and keep it in a safe
place (such as your wallet), not in the vehicle.
If you lose your keys, it is recommended that
you visit an INFINITI retailer for duplicates by
using the key number. INFINITI does not re-
cord key numbers so it is very important to
keep track of your key number plate.
A key number is only necessary when you
have lost all keys and do not have one to
duplicate from. If you still have a key, it can be
duplicated without knowing the key number.
CAUTION
Be sure to carry the Intelligent Key with
you when driving. The Intelligent Key is a
precision device with a built-in transmit-
ter. To avoid damaging it, please note the
following:
– The Intelligent Key is water resistant;
however, wetting may damage the In-
telligent Key. If the Intelligent Key gets
wet, immediately wipe until it is com-
pletely dry.
– Do not bend, drop or strike it against
another object.
– If the outside temperature is below 14°F
(-10°C), the battery of the Intelligent
Key may not function properly.LPD2848

INFINITI VEHICLE IMMOBILIZER
SYSTEM KEYS
Additional or replacement keys:
If you still have a key, the key number is not
necessary when you need extra INFINITI Ve-
hicle Immobilizer System keys. Your existing
key can be duplicated without knowing the
key number. As many as four INFINITI Ve-
hicle Immobilizer System keys can be used
with one vehicle. You should bring all
INFINITI Vehicle Immobilizer System keys
that you have to the INFINITI retailer for
registration. This is because the registration
process will erase the memory of all key
codes previously registered into the INFINITI
Vehicle Immobilizer System. After the regis-
tration process, these components will only
recognize keys coded into the INFINITI Ve-
hicle Immobilizer System during registration.
Any key that is not given to the retailer at the
time of registration will no longer be able to
start your vehicle.
CAUTION
Do not allow the immobilizer system key,
which contains an electrical transponder,
to come into contact with water or salt
water. This could affect system function. When the doors are locked using one of the
following methods, the doors cannot be
opened using the inside or outside door
handles. The doors must be unlocked to open
the doors.
WARNING
• Always have the doors locked while driv-
ing. Along with the use of seat belts, this
provides greater safety in the event of an
accident by helping to prevent persons
from being thrown from the vehicle. This
also helps keep children and others from
unintentionally opening the doors, and
will help keep out intruders.
• Before opening any door, always look for
and avoid oncoming traffic.
• To help avoid risk of injury or death
through unintended operation of the ve-
hicle and/or its systems, including en-
trapment in windows or inadvertent
door lock activation, do not leave chil-
dren, people who require the assistance
of others or pets unattended in your ve-
hicle. Additionally, the temperature in-
side a closed vehicle on a warm day can
quickly become high enough to cause a
significant risk of injury or death to
people and pets.
LOCKING WITH KEY
To lock or unlock the driver’s door, turn the
key toward the front of the vehicle
O1.
To unlock the driver’s door, turn the key to-
ward the rear of the vehicle
O3, then return it
to the neutral position
O2.

INFINITI VEHICLE IMMOBILIZER
SYSTEM
The INFINITI Vehicle Immobilizer System will
not allow the engine to start without the use
of the registered key.
If the engine fails to start using the registered
key, it may be due to interference caused by
another registered key, an automated toll
road device or automated 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 5
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 key.
If the no start condition re-occurs, INFINITI
recommends placing the registered key on a
separate key ring to avoid interference from
other devices. • Make sure the area around the vehicle is
clear.
• Check fluid levels such as engine oil, cool- ant, brake fluid, and windshield-washer
fluid as frequently as possible, or at least
whenever you refuel.
• Check that all windows and lights are clean.
• Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
• Check that all doors are closed.
• Position seat and adjust head restraints/headrests.
• Adjust inside and outside mirrors.
• Fasten seat belts and ask all passengers to do likewise.
• Check the operation of warning lights when the ignition switch is placed in the ON
position. For additional information, see
“Warning lights, indicator lights and audible
reminders” (P. 2-9) 1. Apply the parking brake.
2. Press the Park button to place the vehicle
in P (Park) or move the shift lever to N
(Neutral). P (Park) is recommended.
The starter is designed not to operate if
the shift lever is in any of the driving
positions.
3. Push the ignition switch to the ON posi- tion. Depress the brake pedal and push
the ignition switch to start the engine.
To start the engine immediately, push and
release the ignition switch while depress-
ing the brake pedal with the ignition
switch in any position.
• If the engine is very hard to start in extremely cold weather or when re-
starting, depress the accelerator pedal a
little (approximately 1/3 to the floor)
and while holding, crank the engine. Re-
lease the accelerator pedal when the
engine starts.
