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. 5-87).
The Steering Assist can be activated when
the following conditions are met:
• The ICC system is activated.
• Lane markers on both sides are clearlydetected.
• 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 light
(orange) on the instrument panel flashes to
alert the driver. Then, the LDP system auto-
matically 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 detectionWhen the Steering Assist is activated, it
monitors the driver’s steering wheel
operation.
LSD2972
Starting and driving5-99
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.
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
5-100Starting and driving
–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) –
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

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

The display is located between the speedom-
eter and tachometer.
• Vehicle ahead detection indicator (green):
Indicates when a vehicle is detected ahead.
• Vehicle ahead detection indicator (orange):
The indicator comes on if there is a malfunc-
tion in the DCA system.
DCA SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations of
the DCA system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious injury or
death.
• This system will not adapt automatically
to road conditions. Do not use the sys-
tem on roads with sharp curves, or on icy
roads, in heavy rain or in fog.
• The DCA system will not apply brake
control while the driver’s foot is on the
accelerator pedal.
• As there is a performance limit to the
distance control function, never rely
solely on the DCA system. This system
does not correct careless, inattentive or
absent-minded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed by
depressing the brake pedal, depending
on the distance to the vehicle ahead and
the surrounding circumstances in order
to maintain a safe distance between
vehicles.
LSD3579
5-112Starting and driving
When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the sensor may
detect vehicles in a different lane, or may
temporarily not detect a vehicle traveling
ahead. This may cause the system to work
inappropriately.The detection of vehicles may also be af-
fected by vehicle operation (steering maneu-
ver or traveling position in the lane, etc.) or
vehicle condition.
If this occurs, the system
may warn you by blinking the system indica-
tor and sounding the chime unexpectedly.
You will have to manually control the proper
distance away from the vehicle traveling
ahead.SYSTEM TEMPORARILY
UNAVAILABLE
Condition A:
Under the following conditions, the DCA sys-
tem is automatically canceled. The chime will
sound and the DCA system switch indicator
will blink. The system will not be able to be
