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
1located 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
vehicle information display, and optionally
in the main central area of the display
screen.

SYSTEM OPERATION
The Traffic Sign Recognition (TSR) system
displays the following types of road signs:
ASpeed sign detected (in Canada)
BSpeed sign detected (in USA)
CSpeed sign detected (no speed limit
detected)
D“Do not pass” sign detected

– In areas not covered by the naviga-tion system.
– If there are deviations in relation to the navigation, for example due to
changes in the road routing.
– When overtaking buses or trucks with speed stickers.

∙ Do not place reflective materials, suchas white 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 mark-
ers.
∙ 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 cam-
era unit is damaged due to an accident,
it is recommended that you visit a
NISSAN dealer.

– When the vehicle’s traveling direc-tion does not align with the lane
marker.
– When traveling close to the vehicle in front of you, which obstructs the
lane camera unit detection range.
– When rain, snow or dirt adheres to the windshield in front of the lane
camera unit.
– When the headlights are not bright due to dirt on the lens or if the aim-
ing is not adjusted properly.
– When strong light enters the lane camera unit. (For example, the light
directly shines on the front of the
vehicle at sunrise or sunset.)
– When a sudden change in bright- ness occurs. (For example, when
the vehicle enters or exits a tunnel
or under a bridge.)
While the I-LI system is operating, you may
hear a sound of brake operation. This is
normal and indicates that the I-LI system is
operating properly.SYSTEM TEMPORARILY
UNAVAILABLE
Condition A:
The warning and assist functions of the I-LI
system are not designed to work under the
following conditions: ∙ When you operate the lane change sig- nal and change the traveling lanes in
the direction of the signal. (The I-LI sys-
tem will be deactivated for approxi-
mately 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 warning and assist func-
tions will resume.
Condition B:
The assist function of the I-LI system is not
designed to work under the following con-
ditions (warning is still functional): ∙ When the brake pedal is depressed.
∙
When the steering wheel is turned as far as
necessary for the vehicle to change lanes.
∙ When the vehicle is accelerated during I-LI system operation. ∙ When the Intelligent Cruise Control (ICC)
approach warning occurs.
∙ When the hazard warning flashers are operated.
∙ When driving on a curve at high speed.
Af ter the above conditions have finished
and the necessary operating conditions
are satisfied, the I-LI system application of
the brakes will resume.
Condition C:
If the following messages appear in the
vehicle information display, the I-LI system
will be turned off automatically. ∙ “Not Available Poor Road Conditions”: When the VDC system (except Traction
Control System [TCS] function) or ABS
operates.
∙ “Currently not available”: When the VDC system is turned off.
Action to take:
When the above conditions no longer exist,
turn off the I-LI system. Push the ProPILOT
Assist switch (for vehicles with ProPILOT
Assist) on the steering wheel again to turn
the I-LI system back on.

– Interference by other radarsources
∙ Do not use the ICC system if you are towing a trailer. The system may not
detect a vehicle ahead.
∙ In some road or traffic conditions, a vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. Always
stay alert and avoid using the ICC sys-
tem where not recommended in this
warning section.
The radar sensor will not detect the follow-
ing objects: ∙ Stationary and slow moving vehicles
∙ Pedestrians or objects in the roadway
∙ Oncoming vehicles in the same lane
∙ Motorcycles traveling offset in the travel lane
The sensor generally detects the signals
returned from the vehicle ahead. Therefore,
if the sensor cannot detect the reflection
from the vehicle ahead, the ICC system
may not maintain the selected distance. The following are some conditions in which
the sensor cannot properly detect a ve-
hicle ahead and the system may not oper-
ate properly:
∙ When snow or road spray from traveling vehicles reduces the sensor’s detection.
∙ When your vehicle is towing a trailer, etc.
∙ When excessively heavy baggage is loaded in the rear seat or cargo area of
your vehicle.
The ICC system is designed to automati-
cally check the sensor’s operation within
the limitations of the system.
When the sensor is covered with dirt or is
obstructed, the system will automatically
be canceled. If the sensor is covered with
ice, a transparent or translucent vinyl bag,
etc., the ICC system may not detect them.
In these instances, the vehicle-to-vehicle
distance control mode may not cancel and
may not be able to maintain the selected
following distance from the vehicle ahead.
Be sure to check and clean the sensor
regularly. The detection zone of the radar sensor is
limited. A vehicle ahead must be in the de-
tection zone for the vehicle-to-vehicle dis-
tance detection mode to maintain the se-
lected distance from the vehicle ahead.
A vehicle ahead may move outside of the
detection zone due to its position within
the same lane of travel. Motorcycles may
not be detected in the same lane ahead if
they are traveling offset from the centerline
of the lane. A vehicle that is entering the
lane ahead may not be detected until the
vehicle has completely moved into the
lane.
If this occurs, the ICC system may warn
you by blinking the system indicator and
sounding the chime. The driver may
have to manually control the proper dis-
tance away from vehicle traveling ahead.

∙ Cruise control warning (yellow): Indi-cates that there is a malfunction in
the ICC system
2. Set vehicle speed indicator: This indicator indicates the set vehicle
speed. For Canadian models, the
speed is displayed in km/h.
Operating conventional (fixed
speed) cruise control mode
To turn on the conventional (fixed speed)
cruise control mode, push and hold the ICC
switch
Afor longer than about 1.5 sec-
onds.
When pushing ICC switch on, the conven-
tional (fixed speed) cruise control mode
display and indicators
Bare displayed in
the vehicle information display. Af ter you
hold ICC switch on for longer than about
1.5 seconds, the ICC system display turns
off. The cruise indicator appears. You can
now set your desired cruising speed. Push- ing the ICC switch again will turn the sys-
tem completely off. When the ignition
switch is placed in the OFF position, the
system is also automatically turned off.
To use the ICC system again, quickly push
and release the ICC switch (vehicle-to ve-
hicle distance control mode) or push and
hold it (conventional cruise control mode)
again to turn it on.

If it is not possible to set or the indicator
stays on, it may indicate that the system
is malfunctioning. Although the vehicle
is still drivable under normal conditions,
have the vehicle checked. It is recom-
mended that you visit a NISSAN dealer
for this service.

∙ The ICC system does not react to sta-tionary and slow moving vehicles.
∙ Always drive carefully and attentively when using the ICC system. Read and
understand the Owner’s Manual thor-
oughly before using the ICC system.
To avoid serious injury or death, do
not rely on the system to prevent ac-
cidents or to control the vehicle’s
speed in emergency situations. Do
not use the ICC system except in ap-
propriate road and traffic conditions.
ICC system operation
The ICC system is designed to maintain a
selected distance from the vehicle in front
of you and can reduce the speed to match
a slower vehicle ahead. The system decel-
erates the vehicle as necessary and if the
vehicle ahead comes to a stop, the vehicle
decelerates to a standstill. However, the ICC
system can only apply up to 40% of the
vehicle’s total braking power. This system
should only be used when traffic condi-
tions allow vehicle speeds to remain fairly
constant or when vehicle speeds change
gradually. If a vehicle moves into the travel-
ing lane ahead or if a vehicle traveling
ahead rapidly decelerates, the distance be-
tween vehicles may become closer be- cause the ICC system cannot decelerate
the vehicle quickly enough. If this occurs,
the ICC system sounds a warning chime
and blinks the system display to notif y the
driver to take necessary action.
The ICC system cancels and a warning
chime sounds if the speed is below ap-
proximately 15 mph (24 km/h) and a vehicle
is not detected ahead.
The ICC system operates as follows:
∙ When there are no vehicles traveling ahead, the ICC system maintains the
speed set by the driver. The set speed
range is between approximately 20 and
90 mph (32 and 144 km/h).
∙ When there is a vehicle traveling ahead, the ICC system adjusts the speed to
maintain the distance, selected by the
driver, from the vehicle ahead. If the ve-
hicle ahead comes to a stop, the vehicle
decelerates to a standstill. Once your
vehicle stops, the ICC system keeps the
vehicle stopped.
∙ When your vehicle is stopped for less than 3 seconds and the vehicle ahead
begins to move, your vehicle will start
moving again automatically. ∙ When your vehicle is at a standstill for
more than 3 seconds and the vehicle
ahead begins to accelerate, push the
RES+ switch or lightly depress the accel-
erator pedal. The ICC system starts to
follow the vehicle ahead.
∙ When the vehicle traveling ahead moves to a different traveling lane, the
ICC system accelerates and maintains
vehicle speed up to the set speed.
The ICC system does not control vehicle
speed or warn you when you approach
stationary and slow moving vehicles. You
must pay attention to vehicle operation to
maintain proper distance from vehicles
ahead when approaching toll gates or traf-
fic congestion.
Starting and driving5-103

∙ Always pay attention to the operationof the vehicle and be ready to manu-
ally control the proper following dis-
tance. The ICC system may not be able
to maintain the selected distance be-
tween vehicles (following distance) or
selected vehicle speed under some
circumstances.
∙ The system may not detect the ve- hicle in front of you in certain road or
weather conditions. To avoid acci-
dents, never use the ICC system under
the following conditions:
– On roads with heavy, high-speed traffic or sharp curves
– On slippery road surfaces such as on ice or snow, etc.
– During bad weather (rain, fog, snow, etc.)
– When rain, snow or dirt adhere to the bumper around the distance
sensor
– On steep downhill roads (the ve- hicle may go beyond the set ve-
hicle speed and frequent braking
may result in overheating the
brakes) – On repeated uphill and downhill
roads
– When traffic conditions make it dif- ficult to keep a proper distance be-
tween vehicles because of fre-
quent acceleration or deceleration
– Interference by other radar sources.
∙ Do not use the ICC system if you are towing a trailer. The system may not
detect a vehicle ahead.
∙ In some road or traffic conditions, a vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. Always
stay alert and avoid using the ICC sys-
tem where not recommended in this
warning section.
The ICC system will not detect the following
objects: ∙ Stationary or slow moving vehicles
∙ Pedestrians or objects in the roadway
∙ Oncoming vehicles in the same lane
∙ Motorcycles traveling offset in the travel lane The following are some conditions in which
the radar sensor cannot properly detect a
vehicle ahead and the system may not op-
erate properly:
∙ When the sensor detection is reduced (conditions such as rain, snow, fog, dust
storms, sandstorms, and road spray
from other vehicles)
∙ Driving on a steep downhill slope or roads with sharp curves
∙ Driving on a bumpy road surface, such as an uneven dirt road
∙ If dirt, ice, snow or other material is cov- ering the radar sensor area
∙ A complicated-shaped vehicle such as a car carrier trailer or flatbed
truck/trailer is near the vehicle ahead.
∙ Interference by other radar sources
∙ When your vehicle is towing a trailer, etc.
∙ When excessively heavy baggage is loaded in the rear seat or cargo area of
your vehicle.
The ICC system is designed to automati-
cally check the radar sensor’s operation
within the limitations of the system.
