STEERING ASSIST
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the Steering Assist
could result in serious injury or death.
• The Steering Assist is not a replacement
for proper driving procedures and is not
designed to correct careless, inattentive
or absent-minded driving. The Steering
Assist will not always steer the vehicle to
keep it in the lane. It is not designed to
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.
• As there is a performance limit to the
Steering Assist’s capability, never rely
solely on the system. The Steering Assist
does not function in all driving, traffic,
weather, and road conditions. Always
drive safely, pay attention to the opera-
tion of the vehicle, and manually control
your vehicle appropriately.
• The Steering Assist is intended for use on
well-developed freeways or highways
with gentle (moderate) curves. To avoid
risk of an accident, do not use this system
on local or non-highway roads. •
The Steering Assist only steers the ve-
hicle to maintain its position in the center
of a lane. The vehicle will not steer to
avoid objects in the road in front of the
vehicle or to avoid a vehicle moving into
your lane.
• 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. Never take your
hands off the steering wheel when driv-
ing. Always keep your hands on the
steering wheel and drive your vehicle
safely.
• Always drive carefully and attentively
when using the Steering Assist. Read
and understand the Owner’s Manual
thoroughly before using the Steering As-
sist. To avoid serious injury or death, do
not rely on the system to prevent acci-
dents or to control the vehicle’s speed in
emergency situations. Do not use the
Steering Assist except in appropriate
road and traffic conditions.Steering Assist operation
The Steering Assist controls the steering sys-
tem to help keep your vehicle near the center
of the lane when driving. The Steering Assist
is combined with the Intelligent Cruise Con-
trol (ICC) system. For additional information,
see “Intelligent Cruise Control (ICC) (for ve-
hicles with ProPILOT Assist)” (P. 5-82).
The Steering Assist can be activated when
the following conditions are met:
• The ICC system is activated.
• Lane markers on both sides are clearly detected.
• A vehicle ahead is detected (when the ve- hicle is driven at speeds under 37 mph [60
km/h])
• The driver grips the steering wheel.
• The vehicle is driven at the center of the lane.
• The turn signals are not operated.
• The windshield wiper is not operated in the high (HI) speed operation (the steering as-
sist function is disabled after the wiper op-
erates for approximately 10 seconds).

Lane Departure Prevention (LDP)
When a curve or strong cross wind exceeds
the capabilities of the Steering Assist and
your vehicle approaches either the left or the
right side of the traveling lane, a warning
chime sounds and the LDP indicator (orange)
on the instrument panel flashes to alert the
driver. Then, the LDP system automatically
applies the brakes for a short period of time
to help assist the driver to return the vehicle
to the center of the traveling lane. This action
is in addition to any Steering Assist actions.

Hands on detection
When the Steering Assist is activated, it
monitors the driver’s steering wheel
operation.
If the steering wheel is not operated or the
driver takes his/her hands off the steering
wheel for a period of time, the warning (1)
appears in the vehicle information display.
If the driver does not operate the steering
wheel after the warning has been displayed,
an audible alert sounds and the warning
flashes in the vehicle information display, fol-
lowed by a quick brake application to request
the driver to take control of the vehicle again.
If the driver still does not respond, the ProPI-
LOT Assist turns on the hazard flasher and
slows the vehicle to a complete stop.
The driver can cancel the deceleration at any
time by steering, braking, accelerating, or op-
erating the ProPILOT Assist switch.
WARNING
Steering Assist is not a system for a hands-
free driving. Always keep your hands on
the steering wheel and drive your vehicle
safely. Failure to do so could cause a colli-
sion resulting in serious personal injury or
death.

5-96Starting and driving
NOTE:
If the driver lightly touches (instead of firmly
grips) the steering wheel, the steering
torque sensor may not detect the driver’s
hand(s) on the steering wheel and a sequence
of warnings may occur. When the driver
holds and operates the steering wheel again,
the warnings turn off.
Steering Assist limitations
WARNING
• In the following situations, the camera
may not detect lane markers correctly or
may detect lane markers incorrectly and
the Steering Assist may not operate
properly:
– When driving on roads where there
are multiple parallel lane markers,
lane markers that are faded or not
painted clearly, nonstandard lane
markers, or lane markers covered
with water, dirt, snow, etc.
– When driving on roads with discon-
tinued lane markers
– When driving on roads with a widen-
ing or narrowing lane width –
When driving on roads where there
are multiple lanes or unclear lane
markers due to road construction
– When driving on roads where there
are sharply contrasting objects, such
as shadows, snow, water, wheel ruts,
seams, or lines remaining after road
repairs (the Steering Assist could de-
tect these items as lane markers)
– When driving on roads where the
traveling lane merges or separates
• Do not use the Steering Assist under the
following conditions because the system
may not properly detect lane markers.
Doing so could cause a loss of vehicle
control and result in an accident.
– During bad weather (rain, fog, snow,
dust, etc.)
– When rain, snow, sand, etc., is thrown
up by the wheels of other vehicles
– When dirt, oil, ice, snow, water, or an-
other object adheres to the camera
unit
– When the lens of the camera unit is
foggy
– When strong light (for example, sun-
light or high beams from oncoming
vehicles) shines on the camera –
When the headlights are not bright
due to dirt on the lens or the head-
lights are off in tunnels or darkness
– When a sudden change in brightness
occurs (for example, when the vehicle
enters or exits a tunnel or is under a
bridge)
– When driving on roads where the
traveling lane merges or separates or
where there are temporary lane
markers because of road
construction
– When there is a lane closure due to
road repairs
– When driving on a bumpy road sur-
face, such as an uneven dirt road
– When driving on sharp curves or
winding roads
– When driving on repeated uphill and
downhill roads
• Do not use the Steering Assist under the
following conditions because the system
will not operate properly:
– When driving with a tire that is not
within normal tire conditions (for ex-
ample, tire wear, abnormal tire pres-
sure, installation of a spare tire, tire
chains, nonstandard wheels)
Starting and driving5-97
–When the vehicle is equipped with
non-original brake or suspension
parts
– When an object that obstructs the
camera unit detection range is
attached
– When excessively heavy baggage is
loaded in the rear seat or luggage
area of your vehicle
– When the vehicle load capacity is
exceeded
– When towing a trailer or other vehicle
• Excessive noise will interfere with the
warning chime sound, and the beep may
not be heard.
• For the ProPILOT Assist system to oper-
ate properly, the windshield in front of
the camera must be clean. Replace worn
wiper blades. The correct size wiper
blades must be used to help make sure
the windshield is kept clean. Only use
Genuine INFINITI wiper blades, or
equivalent wiper blades, that are specifi-
cally designed for use on your vehicle
model and model year. It is recommended
that you visit your INFINITI retailer for
the correct parts for your vehicle.Steering Assist temporary standby
Automatic standby due to driving operation:
When the driver activates the turn signal, the
Steering Assist is temporarily placed in a
standby mode. (The Steering Assist restarts
automatically when the operating conditions
are met again.)
Automatic standby:
In the following cases, a warning message is
displayed along with the chime, and the
Steering Assist is placed in a temporary
standby mode. (The Steering Assist restarts
automatically when the operating conditions
are met again.)
• When lane markers on both sides are no longer detected
• When a vehicle ahead is no longer detected under approximately 37 mph (60 km/h)
Steering Assist cancel
Under the following conditions, the Steering
Assist cancels, and the Steering Assist status
indicator and the Steering Assist indicator
turn off: • When unusual lane markers appear in the
traveling lane or when the lane marker can-
not be correctly detected for some time due
to certain conditions (for example, a snow
rut, the reflection of light on a rainy day, the
presence of several unclear lane markers)
• When the windshield wiper operates in the high (HI) speed operation (the Steering As-
sist is disabled when the wiper operates for
more than approximately 10 seconds)
Action to take:
Turn the ICC system off using the CANCEL
switch. When the conditions listed above are
no longer present, turn the ICC system on
again.
Steering Assist malfunction
When the system malfunctions, it turns off
automatically. The Steering Assist status
warning illuminates (orange). A chime may
sound depending on the situation.
Action to take:
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the en-
gine off, restart the engine, resume driving,
and set the Intelligent Cruise Control system
again. If the warning (orange) continues to
illuminate, the Steering Assist is malfunction-
ing. Although the vehicle is still drivable under
5-98Starting and driving
normal conditions, have the system checked.
It is recommended that you visit an INFINITI
retailer for this service.
Steering Assist maintenance
The camera sensor is located above the in-
side mirror.
To keep the proper operation of the system
and prevent a system malfunction, be sure to
observe the following:
• Always keep the windshield clean.
• Do not attach a sticker (including transpar-ent material) or install an accessory near
the camera unit.
• Do not place reflective materials, such as white paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely 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 recommended that you visit an
INFINITI retailer.

CONVENTIONAL (fixed speed)
CRUISE CONTROL MODE
NOTE:
ProPILOT Assist provides no approach
warnings, automatic braking, or steering as-
sist in the conventional (fixed speed) cruise
control mode.
This mode allows driving at a speed between
25 to 90 mph (40 to 144 km/h) without
keeping your foot on the accelerator pedal.
WARNING
• In the conventional (fixed speed) cruise
control mode, a warning chime does not
sound to warn you if you are too close to
the vehicle ahead, as neither the pres-
ence of the vehicle ahead nor the vehicle-
to-vehicle distance is detected.
• Pay special attention to the distance be-
tween your vehicle and the vehicle ahead
of you or a collision could occur.
• Always confirm the setting in the ICC
system display. •
Do not use the conventional (fixed
speed) cruise control mode when driving
under the following conditions:
– When it is not possible to keep the
vehicle at a set speed
– In heavy traffic or in traffic that var-
ies in speed
– On winding or hilly roads
– On slippery roads (rain, snow, ice,
etc.)
– In very windy areas
• Doing so could cause a loss of vehicle
control and result in an accident.
Conventional (fixed speed) cruise
control switches
1. CANCEL switch: Deactivates the system without erasing
the set speed
2. RES+ switch: Resumes set speed or increases speed
incrementally
3. SET- switch: Sets desired cruise speed or reduces
speed incrementally
4. ProPILOT Assist switch: Master switch to activate the system

•When the vehicle approaches an ob-
stacle while the accelerator or brake
pedal is depressed, the function may not
operate or the start of operation may be
delayed. The RAB system may not oper-
ate or may not perform sufficiently due
to vehicle conditions, driving conditions,
the traffic environment, the weather,
road surface conditions, etc. Do not wait
for the system to operate. Operate the
brake pedal by yourself as soon as
necessary.
• If it is necessary to override RAB opera-
tion, strongly press the accelerator
pedal.
• Always check your surroundings and
turn to check what is behind you before
and while backing up. The RAB system
detects stationary objects behind the
vehicle. The RAB system does not detect
the following objects:
– Moving objects
– Low objects
– Narrow objects
– Wedge-shaped objects
– Objects close to the bumper (less than
approximately 1 ft [30 cm])
– 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 materials
or snow, that have soft outer sur-
faces and can easily absorb a sound
wave
• The RAB system may not operate in the
following conditions:
– There is rain, snow, ice, dirt, etc., at-
tached to the sonar sensors.
– A loud sound is heard in the area
around the vehicle.
– The surface of the obstacle is diago-
nal to the rear of the vehicle.
• The RAB system may unintentionally op-
erate 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 oper-
ates, it does not operate again if the ve-
hicle approaches the same obstacle.
• The automatic brake control can only
operate for a short period of time. There-
fore, the driver must depress the brake
pedal.
• In the following situations, the RAB sys-
tem may not operate properly or may not
function sufficiently:
