,,,,
The following lights (if so equipped) will

,,,,,,,, ATP ,
If any light does not come on or operate in
a way other than described, it may indicate
a burned-out bulb and/or a system mal-
function. Have the system checked. It is
recommended that you visit a NISSAN
dealer for this service.
Some indicators and warnings are also dis-
played on the vehicle information display
between the speedometer and tachom-
eter. For additional information, see “Ve-
hicle information display” (P. 2-24).
WARNING/INDICATOR LIGHTS (red)
For additional information, see “Vehicle in-
formation display” (P. 2-24).
Automatic Transmission
Park warning light (
model)
WARNING
• If the 4WD mode indicator is off or the
ATP warning light is on, this indicates
that the automatic transmission P
(Park) position will not function and
could result in the vehicle moving un-
expectedly, causing serious personal
injury or property damage. Always
set the parking brake. For additional
information, see “Using 4–wheel
drive (4WD)” (P. 5-105).
• If the ATP light is on, this indicates
that the automatic transmission P
(Park) position will not function and
the transfer case is in neutral.
• When parking, always make sure that
the 4WD shif t indicator light illumi-
nates and the parking brake is set.
Failure to engage the transfer posi-
tion in 2WD, 4H or 4LO could result in
the vehicle moving unexpectedly, re-
sulting in serious personal injury or
property damage. •
Shif t the 4WD switch into the 2WD, 4H
or 4LO position again to turn off the
ATP warning light when the shif t le-
ver is in the P position and the ATP
warning light is on. (Before shif ting
the 4WD switch into the 4LO position,
move the shif t lever to the N position
once, shif t the shif t lever into P again
and make sure the ATP warning light
is off.)
This light indicates that the automatic
transmission parking function is not en-
gaged. If the transfer control is not secured
in any drive position while the shif t lever is
in the P (Park) position, the transmission will
disengage and the drive wheels will not
lock.
Brake warning light
This light functions for both the parking
brake and the foot brake systems.

2-18Instruments and controls

Your vehicle has two types of security
systems:
• 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 or hood when the system
is armed. It is not, however, a motion detec-
tion type system that activates when a ve-
hicle is moved or when a vibration occurs.The system helps deter vehicle thef t but
cannot prevent it, nor can it prevent the
thef t of interior or exterior vehicle compo-
nents in all situations. Always secure your
vehicle even if parking for a brief period.
Never leave your keys 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 protec-
tion, such as component locks, identifica-
tion markers, and tracking systems, are
available at auto supply stores and spe-
cialty shops. A NISSAN dealer may also offer
such equipment. Check with your insur-
ance company to see if you may be eligible
for discounts for various thef t 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. Lock all doors. The doors can be locked with the Intelligent Key or
door handle request 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
automatically shif t into the armed
phase. The
security light begins to
flash once every three seconds. If during
the pre-armed phase one of the follow-
ing occurs, the system will not arm:
• Any door is unlocked with the Intelligent Key or door request switch.
• Ignition switch is placed in ACC or ON position.
• Even when the driver and/or passen-
gers are in the vehicle, the system will
activate with all the doors, hood and
locked with the ignition switch placed
in the LOCK position. When placing the
ignition switch in the ACC or ON posi-
tion, the system will be released.
• The lockable bedside storage com-
partment (if so equipped) is not pro-
tected by the vehicle security system.

SECURITY SYSTEMS
2-40Instruments and controls

Vehicle security system activation
The vehicle security system will give the
following alarm:
• The headlights blink and the horn soundsintermittently but synchronously.
• The alarm automatically turns off af ter a period of time. However, the alarm reacti-
vates if the vehicle is tampered with
again.
The alarm is activated by:
• opening any door or hood without using the Intelligent Key (even if the door is un-
locked by releasing the door inside lock
knob).
How to stop an activated alarm
The alarm stops only by pressing thebutton on the Intelligent Key.
NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the engine to start without
the use of a registered key. If the engine fails to start using a registered
key (for example, when interference is
caused by another registered key, an auto-
mated toll road device or automatic pay-
ment device on the key ring), restart the
engine using the following procedures:
1. Leave the ignition switch placed in the
ON position 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 inter-
ference) separate from the registered
key.
If the no start condition re-occurs, NISSAN
recommends placing the registered key on
a separate key ring to avoid interference
from other devices. FCC Notice:

Both sides of the storage bin, under the
rear seat on the driver’s and passenger’s
sides, operate similarly. They can be ac-
cessed simultaneously or independently of
each other.
Further, to create a flat floor space for stor-
age, rather than access the storage bin, lif t
the bench seat as before, then lif t the tab
O2and rotate the bin cover toward the
front of the vehicle. Use the tab as a leg to
support the cover as the new floor space.
Cargo can be secured to the extended
floor with bungee cords. Secure the bun-
gee cords to the loops in the extended
floor.
CAUTION
• To avoid damaging the extended
floor, the weight secured should not
exceed 247 lbs. (112 kg).
• To avoid damaging the bungee hook
loops, do not exceed 35 lbs. (16 kg) of
force to any given loop.
CAUTION
• To avoid damaging the extended
floor, the leg of the extended floor
must be perpendicular to the floor
before any weight is applied.
• To avoid damaging the extended
floor, ensure that the under-seat
storage area is completely stowed
before lowering the rear seat
bottom.
