equipped)
This warning illuminates when there is a
problem with the engine. If this warning
comes on, have the system checked. It is
recommended that you visit a NISSAN
dealer for this service.
Engine hot Power reduced (if so
equipped)
This engine has a high fluid temperature
protection mode. If the fluid temperature
becomes too high (for example, climbing
steep grades in high temperatures with
heavy loads, such as when towing a trailer),
engine power and, under some conditions,
vehicle speed will be decreased automati-
cally to reduce the chance of engine dam-
age. Vehicle speed can be controlled with
the accelerator pedal, but the engine and
vehicle speed may be reduced.

Your vehicle may have two types of security
systems:
• Vehicle security system (if so equipped)
• NISSAN Vehicle Immobilizer System
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 detec-
tion type system that activates when a ve-
hicle is moved or when a vibration occurs.The system helps detect 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 and the moonroof.
The system can be armed even if the
windows and moonroof are open.
2. Remove the Intelligent Key from the vehicle. 3. Close all doors, hood and trunk. 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 (if so
equipped).
4. Wait 30 seconds for the system to com- plete the pre-armed phase.
If during the pre-armed phase one of
the following occurs, the system will not
arm:
• Any door is unlocked with the me- chanical key (if so equipped), Intelli-
gent Key or door request switch (if so
equipped).
• The ignition switch is placed in the AUTO ACC or ON position.
• Even when the driver and/or passen-
gers are in the vehicle, the system will
activate when all the doors, hood and
trunk are locked with the ignition
switch placed in the LOCK position.
When placing the ignition switch in the
ON position, the system will be re-
leased.

Vehicle security system activation
The vehicle security system will give the
following alarm:
• The headlights blink and the horn soundsintermittently.
• 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 can be shut off by un-
locking the driver's door or trunk lid with
the key, or by pressing the
button on
the Intelligent Key.
The alarm is activated by:
• opening the door or trunk lid without us- ing the key or Intelligent Key (even if the
door is unlocked by releasing the door
inside lock switch).
How to stop an activated alarm
The alarm stops only by unlocking a door
or the trunk with the mechanical key (if so
equipped), pressing the
button on the
Intelligent Key, or pushing the request
switch (if so equipped) on the driver's or
passenger's door with the Intelligent Key in
range of the door handle.
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 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 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.
Never leave these keys in the vehicle. FCC Notice:

Autolight system
The autolight system allows the headlights
to turn on and off automatically. The auto-
light system can:
• Turn on the headlights, front parking, tail,license plate and instrument panel lights
automatically when it is dark.
• Turn off all the lights when it is light.
• Keep all the lights on for a period of time af ter you place the ignition switch in the
OFF position and all doors are closed.
NOTE:
Autolight activation sensitivity and
the time delay for autolight shutoff
can be adjusted. For additional infor-
mation, refer to “Vehicle information
display ” in this section.
To turn on the autolight system:
1. Turn the headlight switch to the AUTO position
O1.
2. Turn the ignition switch to ON.
3. The autolight system automatically turns the headlights on and off.
Initially, if the ignition switch is placed in the
OFF position and a door is opened and lef t
open, the headlights remain on for a period
of time. If another door is opened while the
headlights are on, then the timer is reset.
To turn the autolight system off, turn the
switch to the OFF,
,orposition. Be sure you do not put anything on top
of the autolight sensor located in the top
side
O1of the instrument panel. The au-
tolight sensor controls the autolight; if it
is covered, the autolight sensor reacts as
if it is dark out and the headlights will
illuminate. If this occurs while parked
with the engine off and the ignition
switch placed in the ON position, your
vehicle's battery could become dis-
charged.

High Beam Assist
The High Beam Assist system will operate
when the vehicle is driven at speeds of ap-
proximately 40 km/h (25 mph) and above. If
an oncoming vehicle or leading vehicle ap-
pears in front of your vehicle when the
headlight high beam is on, the headlight
will be switched to the low beam automati-
cally.

•The timing of switching the low
beam and high beam may change
under the following situations.
– The brightness of the headlights
of the oncoming vehicle or leading
vehicle.
– The movement and direction of
the oncoming vehicle and the
leading vehicle.
– When only one light on the on-
coming vehicle or the leading ve-
hicle is illuminated.
– When the oncoming vehicle or the
leading vehicle is a two-wheeled
vehicle.
– Road conditions (incline, curve,
the road surface, etc.).
– The number of passengers and
the amount of luggage.
High Beam Assist operation
To activate the High Beam Assist system,
turn the headlight switch to the AUTO po-
sition
O1and push the lever forwardO2
(high beam position). TheHigh Beam
Assist indicator light in the meter will illumi-
nate while the headlights are turned on.
If the High Beam Assist indicator light does
not illuminate in the above condition, it may
indicate that the system is not functioning
properly. Have the system checked, it is
recommended that you visit a NISSAN
dealer for this service. When the vehicle speed lowers to less than
approximately 25 km/h (16 mph), the head-
light uses the low beam.
To turn off the High Beam Assist system,
turn the headlight switch to the
posi-
tion or select the low beam position by
placing the lever in the neutral position.

Beam Assist system is located in front of
the inside mirror. To maintain the proper
operation of the high beam assist system
and prevent a system malfunction, be sure
to observe the following:
• Always keep the windshield clean.
• Do not attach a sticker (including trans- parent material) or install an accessory
near the ambient image sensor.
• Do not strike or damage the areas around the ambient image sensor. Do
