NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the engine to start without
the use of the 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 procedure:
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. • 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.
• Lock all doors.
• Position seat and adjust headrests/head restraints.
• 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 pushed to the
ON position. For additional information,
see “Warning lights, indicator lights and
audible reminders” (P. 2-9). 1. Apply the parking brake.
2. Move the shif t lever to P (Park) or N (Neu-
tral). P (Park) is recommended.
The starter is designed not to operate
if the shif t 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 de-
pressing the brake pedal with the igni-
tion 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 en-
gine. Release the accelerator pedal
when the engine starts.
• If the engine is very hard to start be- cause it is flooded, depress the accel-
erator pedal all the way to the floor
and hold it. Push the ignition switch to
the ON position to start cranking the
engine. Af ter 5 or 6 seconds, stop
cranking by pushing the ignition
switch to the LOCK position. Af ter

Parking
When the shif t lever is in the P (Park) posi-
tion with the brake force maintained by the
automatic brake hold function, the parking
brake will automatically be applied and the
brake force of the automatic brake hold will
be released. The automatic brake hold in-
dicator light turns off. When the parking
brake is applied with the brake force main-
tained by the automatic brake hold func-
tion, the brake force of the automatic brake
hold will be released. The automatic brake
hold indicator light turns off.
NOTE:
• Under the following conditions, theparking brake will automatically be ap-
plied and the brake force of the auto-
matic brake hold will be released:– The braking force is applied by the automatic brake hold function for 3
minutes or longer.
– The driver's seat belt is unfastened.
– The ignition switch is placed in the OFF position.
– If a malfunction occurs in the auto- matic brake hold function. • When the vehicle stops, but the brake
force is not automatically applied, de-
press the brake pedal firmly until the
automatic brake hold indicator light
(green) illuminates.
The TSR system provides the driver with
information about the most recently de-
tected speed limit. The system captures
the road sign information with the multi-
sensing front camera unit
O1located on
the windshield in front of the inside rear-
view mirror and displays the detected
signs in the vehicle information display. For
vehicles equipped with a navigation sys-
tem, the speed limit displayed is based on a
combination of navigation system data
and live camera recognition. TSR informa-
tion is always displayed at the top of the

SYSTEM MAINTENANCE
The TSR system uses the same multi-
sensing front camera unit that is used by
the Lane Departure Warning (LDW) system,
located in front of the interior rearview mir-
ror. For additional information, see ”System
maintenance” (P. 5-39).
WARNING
Failure to follow the warnings and in-
structions for proper use of the LDW
system could result in serious injury or
death.
• This system is only a warning device
to inform the driver of a potential un-
intended lane departure. It will not
steer the vehicle or prevent loss of
control. It is the driver’s responsibility
to stay alert, drive safely, keep the
vehicle in the traveling lane, and be in
control of the vehicle at all times. The LDW system will operate when the ve-
hicle is driven at speeds of approximately
37 mph (60 km/h) and above, and only
when the lane markings are clearly visible
on the road.
The LDW system monitors the lane mark-
ers on the traveling lane using the camera
unit
OAlocated above the inside mirror.
The LDW system warns the driver that the
vehicle is beginning to leave the driving
lane with an indicator and a steering wheel
vibration. For additional information, see
“LDW system operation” (P. 5-34).

The LDW system is not designed to warn
under the following conditions:
• When you operate the lane change signaland change traveling lanes in the direc-
tion of the signal. (The LDW system will
become operable again approximately 2
seconds af ter the lane change signal is
turned off.)
• When the vehicle speed lowers to less than approximately 37 mph (60 km/h).
Af ter the above conditions have finished
and the necessary operating conditions
are satisfied, the LDW functions will resume.
SYSTEM MALFUNCTION
If the LDW system malfunctions, it will can-
cel automatically and “Not Available Sys-
tem Malfunction” or “System fault” will ap-
pear in the vehicle information display. If
“Not Available System Malfunction” or “Sys-
tem fault” appears in the vehicle informa-
tion display, pull off the road to a safe loca-
tion and stop the vehicle. Place the shif t
lever in the P (Park) position and the ignition
switch in the OFF position and restart the
engine/motor. If “Not Available System Mal-
function” or “System fault” continues to ap-
pear in the vehicle information display,
have the system checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
SYSTEM MAINTENANCE
The lane camera unitO1for the LDW sys-
tem is located above the inside mirror. To
keep the proper operation of the LDW sys-
tem and prevent a system malfunction, be

• Do not place reflective materials, such aswhite paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit’s
capability of detecting the lane markers.
• Do not strike or damage the areas around the camera unit. Do not touch the
camera lens or remove the screw located
on the camera unit. If the camera unit is
damaged due to an accident, it is recom-
mended that you visit a NISSAN dealer.
WARNING
Failure to follow the warnings and in-
structions for proper use of the I-LI sys-
tem could result in serious injury or
death.
• The I-LI system will not steer the ve-
hicle or prevent loss of control. It is
the driver’s responsibility to stay
alert, drive safely, keep the vehicle in
the traveling lane, and be in control of
the vehicle at all times. •
The I-LI system is primarily intended
for use on well-developed freeways
or highways. It may not detect the
lane markers in certain road,
weather, or driving conditions.
The I-LI system must be turned on with the
ProPILOT Assist switch (for vehicles with
ProPILOT Assist) on the steering wheel, ev-
ery time the ignition is placed in the ON
position.
The I-LI system will operate when the ve-
hicle is driven at speeds of approximately
37 mph (60 km/h) and above, and only
when the lane markings are clearly visible
on the road.
The I-LI system warns the driver when the
vehicle has lef t the center of the traveling
lane with an indicator and a steering wheel
vibration. The system helps assist the
driver to return the vehicle to the center of
the traveling lane by applying the brakes to
the lef t or right wheels individually (for a
short period of time).
The I-LI system monitors the lane markers
on the traveling lane using the camera unit

WARNING
Failure to follow the warnings and in-
structions for proper use of the BSW
system could result in serious injury or
death.
• The BSW system is not a replacement
for proper driving procedures and is
not designed to prevent contact with
vehicles or objects. When changing
lanes, always use the side and rear
mirrors and turn and look in the di-
rection your vehicle will move to en-
sure it is safe to change lanes. Never
rely solely on the BSW system.
The BSW system helps alert the driver of
other vehicles in adjacent lanes when
changing lanes. The BSW system uses radar sensors
O1
installed near the rear bumper to detect
other vehicles in an adjacent lane.
The radar sensors can detect vehicles on
either side of your vehicle within the detec-
tion zone shown as illustrated. This detec-
tion zone starts from the outside mirror of
your vehicle and extends approximately 10
f t (3.0 m) behind the rear bumper, and ap-
proximately 10 f t (3.0 m) sideways.

could result in serious injury or death.
• The RCTA system is not a replace-
ment for proper driving procedures
and is not designed to prevent con-
tact with vehicles or objects. When
backing out of a parking space, al-
ways use the side and rear mirrors
and turn and look in the direction
your vehicle will move. Never rely
solely on the RCTA system.
The RCTA system will assist you when
backing out from a parking space. When
the vehicle is in reverse, the system is de-
signed to detect other vehicles approach-
ing from the right or lef t of the vehicle. If the
system detects cross traffic, it will alert you.
