Automatic transmissionpark warning light
(
model)
WARNING
∙ 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 lever
is in the P position and the ATP warn-
ing light is ON. (Before shif ting the
4WD switch into the 4LO position,
move the shif t lever into the N posi-
tion 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

2. If the brake fluid level is correct, havethe warning system checked. It is rec-
ommended that you visit a NISSAN
dealer for this service.
WARNING
∙ Your brake system may not be work-ing properly if the warning light is on.
Driving could be dangerous. If you
judge it to be safe, drive carefully to
the nearest service station for repairs.
Otherwise, have your vehicle towed
because driving it could be
dangerous.
∙ Pressing the brake pedal with the en- gine stopped and/or a low brake fluid
level may increase your stopping dis-
tance and braking will require greater
pedal effort as well as pedal travel.
∙ If the brake fluid level is below the MINIMUM or MIN mark on the brake
fluid reservoir, do not drive until the
brake system has been checked. It is
recommended that you visit a NISSAN
dealer for this service. Anti-lock Braking System (ABS)
warning indicator
When the parking brake is released and the
brake fluid level is sufficient, if both the
brake warning light and the ABS warning
light illuminate, it may indicate the ABS is
not functioning properly. Have the brake
system checked and, if necessary, repaired.
It is recommended that you visit a NISSAN
dealer for this service. Avoid high-speed
driving and abrupt braking. For additional
information, refer to “Anti-lock Braking Sys-
tem (ABS) warning light” in this section.

light remains on, have the system checked.
It is recommended that you visit a NISSAN
dealer for this service.
CAUTION
∙ Do not ground electrical accessories
directly to the battery terminal. Doing
so will bypass the variable voltage
control system and the vehicle bat-
tery may not charge completely. For
additional information, refer to “Vari-
able voltage control system” in the
“Do-it-yourself ” section of this
manual.

shif t switch to 4LO.
The indicator light may blink while shif t-
ing from one drive mode to the other. The 4LO indicator light must stop blinking

Your vehicle may have two types of security
systems:∙ Vehicle security system (if so equipped)
∙ NISSAN Vehicle Immobilizer System (if so equipped)
VEHICLE SECURITY SYSTEM
(if so equipped)
The vehicle security system provides visual
and audible alarm signals if someone
opens the doors when the system is
armed. It is not, however, a motion
detection-type system that activates
when a vehicle is moved or when a vibra-
tion 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 ignition, 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 key from the ignition switch.
3. Close all doors. Lock all doors. The doors can be locked with the key, power door lock switch (if the door is
opened, locked and then closed), or
with the key fob.
Key fob operation:
∙ Press the
button on the key
fob. All doors lock. The hazard lights
flash twice and the horn beeps once
to indicate all doors are locked.
∙ When the
button is pressed
with all doors locked, the hazard
lights flash twice and the horn beeps
once as a reminder that the doors
are already locked.
The horn may or may not beep. For
additional information, refer to “Silenc-
ing the horn beep feature” in the “Pre-
driving checks and adjustments” sec-
tion of this manual.
4. Confirm that the
indicator light
comes on. The
light stays on for
about 30 seconds. The vehicle security
system is now pre-armed. Af ter about
30 seconds the vehicle security system
automatically shif ts into the armed
phase. The
light begins to flash
once every 3 seconds. If, during the 30-
second pre-arm time period, the driv-
er’s door is unlocked by the key or the

key fob, or the ignition switch is placed
in ACC or ON position, the system will
not arm.
∙ If the key is turned slowly when lock-
ing the driver’s door, the system may
not arm. Furthermore, if the key is
turned beyond the vertical position
toward the unlock position the sys-
tem may be disarmed when the key is
removed. If the indicator light fails to
glow for a period of time, unlock the
door once and lock it again.
∙ Even when the driver and/or passen-
gers are in the vehicle, the system will
arm with all doors closed and locked
with the ignition switch placed in the
OFF position.
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 af ter
a period 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 with the key
or by pressing the
button on the
key fob.
The alarm is activated by:
∙ Opening a door without using the key or key fob (even if the door is unlocked by
using the inside lock knob or the power
door lock switch).
How to stop an activated alarm
The alarm stops only by unlocking the driv-
er’s door with the key or by pressing
the
button on the key fob.
NISSAN VEHICLE IMMOBILIZER
SYSTEM (if so equipped)
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 in the ON po- sition for approximately 5 seconds.
2. Turn the ignition switch to the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device (which may have caused the in-
terference) separate from the regis-
tered 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.
