•Do not use the LDW system under the
following conditions as it may not
function properly:
– During bad weather (rain, fog,
snow, etc.).
– When driving on slippery roads,
such as on ice or snow.
– When driving on winding or un-
even roads.
– When there is a lane closure due to
road repairs.
– When driving in a makeshif t or
temporary lane.
– When driving on roads where the
lane width is too narrow.
– When driving without normal tire
conditions (for example, tire wear,
low tire pressure, installation of
spare tire, tire chains, nonstan-
dard wheels).
– When the vehicle is equipped with
non-original brake parts or sus-
pension parts.
– When you are towing a trailer or
other vehicle.

•The system may not function prop-
erly under the following conditions:
– On roads where there are multiple
parallel lane markers; lane mark-
ers that are faded or not painted
clearly; yellow painted lane mark-
ers; non-standard lane markers;
or lane markers covered with wa-
ter, dirt, snow, etc.
– On roads where the discontinued
lane markers are still detectable.
– On roads where there are sharp
curves.
– On roads where there are sharply
contrasting objects, such as shad-
ows, snow, water, wheel ruts,
seams or lines remaining af ter
road repairs. (The LDW system
could detect these items as lane
markers.)
– On roads where the traveling lane
merges or separates.
– When the vehicle’s traveling direc-
tion does not align with the lane
marker.
– When traveling close to the ve-
hicle in front of you, which ob-
structs the lane camera unit de-
tection range. –
When rain, snow, dirt or an object
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 aiming 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.)
SYSTEM TEMPORARILY
UNAVAILABLE
If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 104°F [40°C]) and then
started, the LDW system may be deacti-
vated automatically and the following
message will appear in the vehicle infor-
mation display: “Unavailable: High Cabin
Temperature.”
When the interior temperature is reduced,
the LDW system will resume operating au-
tomatically. The LDW system is not designed to warn
under the following conditions:
• When you operate the lane change signal
and 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” will appear in the vehicle
information display. If “Not Available Sys-
tem Malfunction” appears in the vehicle in-
formation display, pull off the road to a safe
location and stop the vehicle. Place the
shif t lever in the P (Park) position and the
ignition switch in the OFF position and re-
start the engine/motor. If “Not Available
System Malfunction” continues to appear
in the vehicle information display, have the
system checked. It is recommended that
you visit a NISSAN dealer for this service.
5-34Starting and driving

When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC system will adjust the speed
to maintain the distance, selected by the
driver, from the vehicle ahead. If the vehicle
ahead changes lanes or exits the freeway,
the ICC system will accelerate and main-
tain the speed up to the set speed. Pay
attention to the driving operation to main-
tain control of the vehicle as it accelerates
to the set speed.Normally when controlling the distance to
a vehicle ahead, this system automatically
accelerates or decelerates your vehicle ac-
cording to the speed of the vehicle ahead.
Depress the accelerator to properly accel-
erate your vehicle when acceleration is re-
quired for a lane change. Depress the brake
pedal when deceleration is required to
maintain a safe distance to the vehicle
ahead due to its sudden braking or if a
vehicle cuts in. Always stay alert when us-
ing the ICC system.THE ICC SWITCH
The system is operated by the ICC switch
and four control switches, all mounted on
the steering wheel.
1.
CANCEL switch:
Deactivates the system without erasing
the set speed.
2. RES+ switch:
Resumes set speed or increases speed
incrementally.

Operating ICC
To turn on the cruise control,quickly push
and release the ICC switch
OA. The ICC sys-
tem ON indicator (white), set distance indi-
cator and set vehicle speed indicator come
on in a standby state for setting. To set cruising speed,
accelerate your ve-
hicle to the desired speed, push the SET-
switch and release it. The ICC system set
indicator (green), vehicle ahead detection
indicator, set distance indicator and set ve-
hicle speed indicator
OBwill come on. Take
your foot off the accelerator pedal. Your
vehicle will maintain the set speed.
When the SET- switch is pushed under the
following conditions, the system cannot be
set and the ICC indicators will blink for ap-
proximately 2 seconds:
• When traveling below 20 mph (32 km/h) and a vehicle ahead is not detected • When the shif t lever is not in the D (Drive)
or L (Low) (if so equipped) position
• When the parking brake is applied
• When the brakes are operated by the driver
When the SET- switch is pushed under the
following conditions, the system cannot be
set.
A warning chime will sound and a message
will pop up:
• When the VDC system is off (To use the ICC system, turn on the VDC system. Push
the ICC switch to turn off the ICC system
and reset the ICC switch by pushing the
ICC switch again.)
For additional information about the
VDC system, refer to “Vehicle Dynamic
Control (VDC) system” in this section.
• When ABS or VDC is operating
• When a wheel is slipping (To use the ICC system, make sure the wheels are no lon-
ger slipping. Push the ICC switch to turn
off the ICC system, and reset the ICC sys-
tem by pushing the ICC switch again.)

RAB SYSTEM OPERATION
1RAB system warning light and RAB sys-
tem warning indicator
2Steering-wheel-mounted controls (lef t
side)
3Center display
When the shif t lever is in the R (Reverse)
position and the vehicle speed is less than
approximately 9 mph (15 km/h), the RAB
system operates.
If a risk of a collision with an obstacle is
detected when your vehicle is backing up,
the RAB system warning indicator will flash
in the vehicle information display, a red
frame will appear in the center display (for
vehicles with the Intelligent Around View
Monitor system), and the system will chime
three times. The system will then auto-
matically apply the brakes. Af ter the auto-
matic brake application, the driver must
depress the brake pedal to maintain brake
pressure.
NOTE:
• The brake lights of the vehicle come on when braking is performed by the RAB
system.
• When the brakes operate, a noise may be heard. This is not a malfunction.
Starting and driving5-75

–Objects that suddenly appear
– Thin objects such as rope, wire,
chain, etc.
• The RAB system may not operate for
the following obstacles:
– Obstacles located high off the
ground
– Obstacles in a position offset from
your vehicle
– Obstacles, such as spongy materi-
als or snow, that have sof t outer
surfaces and can easily absorb a
sound wave
• The RAB system may not operate in
the following conditions:
– There is rain, snow, ice, dirt, etc.,
attached to the sonar sensors.
– A loud sound is heard in the area
around the vehicle.
– The surface of the obstacle is di-
agonal to the rear of the vehicle.
• The RAB system may unintentionally
operate in the following conditions:
– There is overgrown grass in the
area around the vehicle. –
There is a structure (e.g., a wall, toll
gate equipment, a narrow tunnel,
a parking lot gate) near the side of
the vehicle.
– There are bumps, protrusions, or
manhole covers on the road
surface.
– The vehicle drives through a
draped flag or a curtain.
– There is an accumulation of snow
or ice behind the vehicle.
– An ultrasonic wave source, such as
another vehicle’s sonar, is near
the vehicle.
• Once the automatic brake control
operates, it does not operate again if
the vehicle approaches the same
obstacle.
• The automatic brake control can only
operate for a short period of time.
Therefore, the driver must depress
the brake pedal.
• In the following situations, the RAB
system may not operate properly or
may not function sufficiently:
– The vehicle is driven in bad
weather (rain, fog, snow, etc.).
– The vehicle is driven on a steep
hill. –
The vehicle’s posture is changed
(e.g., when driving over a bump).
– The vehicle is driven on a slippery
road.
– The vehicle is turned sharply by
turning the steering wheel fully.
– Snow chains are used.
– Wheels or tires other than NISSAN
recommended are used.
– The brakes are cold at low ambi-
ent temperatures or immediately
af ter driving has started.
– The braking force becomes poor
due to wet brakes af ter driving
through a puddle or washing the
vehicle.
• Turn the RAB system off in the follow-
ing conditions to prevent the occur-
rence of an unexpected accident re-
sulting from sudden system
operation:
– The vehicle is towed.
– The vehicle is carried on a flatbed
truck.
– The vehicle is on the chassis
dynamometer.
– The vehicle drives on an uneven
road surface.

becomes imminent, the AEB with Pedes-
trian Detection system applies harder
braking automatically.
While the AEB with Pedestrian Detection
system is operating, you may hear the
sound of brake operation. This is normal
and indicates that the AEB with Pedestrian
Detection system is operating properly.
NOTE:
The vehicle’s brake lights come on when
any braking is performed by the AEB
with Pedestrian Detection system.
Depending on vehicle speed and distance
to the vehicle or pedestrian ahead, as well
as driving and roadway conditions, the sys-
tem may help the driver avoid a forward
collision or may help mitigate the conse-
quences if a collision should be unavoid-
able. If the driver is handling the steering
wheel, accelerating or braking, the AEB with
Pedestrian Detection system will function
later or will not function.
The automatic braking will cease under the
following conditions:
• When the steering wheel is turned toavoid a collision.
• When the accelerator pedal is depressed. • When there is no longer a vehicle or a
pedestrian detected ahead.
If the AEB with Pedestrian Detection sys-
tem has stopped the vehicle, the vehicle
will remain at a standstill for approximately
2 seconds before the brakes are released.
5-84Starting and driving

–Pedestrians in wheelchairs or us-
ing mobile transport such as
scooters, child-operated toys, or
skateboards.
– Pedestrians who are seated or
otherwise not in a full upright
standing or walking position.
– Oncoming vehicles
– Crossing vehicles
– Obstacles on the roadside
• The AEB with Pedestrian Detection
system has some performance
limitations.
– If a stationary vehicle is in the ve-
hicle’s path, the AEB with Pedes-
trian Detection system will not
function when the vehicle is
driven at speeds over approxi-
mately 50 mph (80 km/h).
– For pedestrian detection, the AEB
with Pedestrian Detection system
will not function when the vehicle
is driven at speeds over approxi-
mately 37 mph (60 km/h) or below
approximately 6 mph (10 km/h).
• The AEB with Pedestrian Detection
system will not function for pedestri-
ans in darkness or in tunnels, even if
there is street lighting in the area. •
The AEB with Pedestrian Detection
system may not function if the ve-
hicle ahead is narrow (for example, a
motorcycle).
• The AEB with Pedestrian Detection
system may not function if the speed
difference between the two vehicles
is too small.
• The radar sensor AEB with Pedes-
trian Detection system may not
function properly or detect a vehicle
ahead in the following conditions:
– Poor visibility (conditions such as
rain, snow, fog, dust storms, sand-
storms, 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 covering the radar sensor area.
– Interference by other radar
sources.
– The camera area of the windshield
is fogged up, or covered with dirt,
water drops, ice, snow, etc. –
Strong light (for example, sunlight
or high beams from oncoming ve-
hicles) enters the front camera.
Strong light causes the area
around the pedestrian to be cast
in a shadow, making it difficult to
see.
– A sudden change in brightness
occurs. (For example, when the
vehicle enters or exits a tunnel or a
shaded area or lightning flashes.)
– The poor contrast of a person to
the background, such as having
clothing color or pattern which is
similar to the background.
– The pedestrian’s profile is partially
obscured or unidentifiable due to
the pedestrian transporting lug-
gage, wearing bulky or very loose-
fitting clothing or accessories.
• The system performance may de-
grade in the following conditions:
– The vehicle is driven on a slippery
road.
– The vehicle is driven on a slope.
– Excessively heavy baggage is
loaded in the rear seat or the trunk
room of your vehicle.

11.ECO Mode
• The ECO mode helps to enhance the fuel economy by controlling the en-
gine and Continuously Variable Trans-
mission (if so equipped) operation au-
tomatically to avoid rapid
acceleration. • Keep your engine tuned up.
• Follow the recommended scheduled
maintenance.
• Keep the tires inflated to the correct pres- sure. Low tire pressure increases tire
wear and lowers fuel economy.
• Keep the wheels in correct alignment. Im- proper alignment increases tire wear and
lowers fuel economy.
• Use the recommended viscosity engine oil. For additional information, refer to “En-
gine oil and oil filter recommendations” in
the “Technical and consumer informa-
tion” section of this manual.
