–

When traffic conditions make it diffi-

cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration

–

Interference by other radar sources.

•

Do not use the ICC system if you are
towing a trailer. The system may not de-
tect a vehicle ahead.

•

In some road or traffic conditions, a ve-
hicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. Always stay alert
and avoid using the ICC system 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 oper-
ate properly:

• When the sensor detection is reduced (con-

ditions 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 cover-

ing 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 automatically
check the radar sensor’s operation within the
limitations of the system.

The detection zone of the radar sensor is
limited. A vehicle ahead must be in the detec-
tion zone for the ICC system to maintain the
selected distance from the vehicle ahead. A
vehicle ahead may move outside of the de-
tection 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 center line 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 distance away from the
vehicle traveling ahead.

The ICC system (with ProPILOT Assist) uses
a multi-sensing front camera. The following
are some conditions in which the camera may
not properly detect a vehicle and detection of
a vehicle ahead may be delayed:
• Poor visibility (conditions such as rain,

snow, fog, dust storms, sandstorms, and
road spray from other vehicles)

• 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 vehicles) enters the
front camera

• A sudden change in brightness occurs (for

example, when the vehicle enters or exits a
tunnel or shaded area or lightning flashes)

5-94

Starting and driving

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the radar sen-
sor may detect vehicles in a different lane, or
may temporarily not detect a vehicle traveling
ahead. This may cause the radar system to
decelerate or accelerate the vehicle.

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 ICC system may warn you
by blinking the system indicator and sounding
the chime unexpectedly. You will have to
manually control the proper distance away
from the vehicle traveling ahead.

Automatic cancellation

The following are conditions in which the ICC
system may be temporarily unavailable. In
these instances, the ICC system may not can-
cel and may not be able to maintain the se-
lected following distance from the vehicle
ahead.

Condition A

Under the following conditions, the ICC sys-
tem is automatically canceled. A chime will
sound and the system will not be able to be
set:
• Any door is open.
• The driver’s seat belt is not fastened.
• The vehicle ahead is not detected and your

vehicle is traveling below the speed of 15
mph (25 km/h).

• Your vehicle has been stopped by the ICC

system for approximately 3 minutes or
longer.

• The shift lever is not in the D (Drive) position

or manual shift mode.

• The electronic parking brake is applied.
• The VDC system is turned off.
• The Forward Emergency Braking with Pe-

destrian Detection applies harder braking.

• VDC (including the traction control system)

operates.

• A wheel slips.
• When distance measurement becomes im-

paired due to adhesion of dirt or obstruc-
tion to the sensor.

• When the radar signal is temporarily

interrupted.

Blocked” warning message continues to be
displayed, have the system checked. It is rec-
ommended that you visit an INFINITI retailer
for this service.

Condition C

When driving on roads with limited road
structures or buildings (for example, long
bridges, deserts, snow fields, driving next to
long walls), the system may illuminate the
system warning light and display the “Un-
available: Front Radar Blocked” message.

Action to take:

When the above driving conditions no longer
exist, turn the system back on.

ICC system malfunction

If the ICC system malfunctions, it will be
turned off automatically, a chime will sound,
and the speed control status warning (or-
ange) will illuminate.

Action to take:

If the warning light comes on, stop the vehicle
in a safe place. Turn the engine off, restart
the engine and set the ICC system again. If it
is not possible to set the ICC system or the
indicator stays on, it may be a malfunction.
Although the normal driving can be contin-
ued, the ICC system should be inspected. It is
recommended that you visit an INFINITI re-
tailer for this service.

ICC sensor maintenance

The radar sensor is located on the front of the
vehicle.

To keep the ICC system operating properly,
be sure to observe the following:
• Always keep the sensor area clean.
• Do not strike or damage the areas around

the sensor.

• Do not attach a sticker (including transpar-

ent material) or install an accessory near
the sensor. This could cause failure or
malfunction.

5-96

Starting and driving

• Do not attach metallic objects near the

sensor area (brush guard, etc.). This could
cause failure or malfunction.

• Do not alter, remove, or paint the front

bumper.

Before customizing or restoring the front
bumper, it is recommended that you visit an
INFINITI retailer.

The camera sensor is located above the in-
side mirror.

To keep the proper operation of the systems
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.

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.

Starting and driving

5-97

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 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 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 detection

When the Steering Assist is activated, it
monitors

the

driver’s

steering

wheel

operation.

LSD2972

Starting and driving

5-99

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.

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.

WARNING

Failure to follow the warnings and instruc-
tions for proper use of the DCA system
could result in serious injury or death.

•

Always drive carefully and attentively
when using the DCA system. Read and
understand the Owner’s Manual thor-
oughly before using the DCA system. To
avoid serious injury or death, do not rely
on the system to prevent accidents or to
control the vehicle’s speed in emergency
situations. Do not use the DCA system
except in appropriate road and traffic
conditions.

•

The system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is the driver’s re-
sponsibility to stay alert, drive safely and
be in control of the vehicle at all times.

DISTANCE CONTROL ASSIST (DCA)
(if so equipped)

5-106

Starting and driving

•

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.

•

Always pay attention to the operation of
the vehicle and be ready to manually de-
celerate to maintain the proper follow-
ing distance. The DCA system may not be
able to decelerate the vehicle under some
circumstances.

•

This system only brakes and moves the
accelerator pedal upward to help assist
the driver to maintain a following dis-
tance from the vehicle ahead. Accelera-
tion should be operated by the driver.

•

The DCA system does not control the ve-
hicle speed or warn you when you ap-
proach stationary and slow moving ve-
hicles. You must pay attention to vehicle
operation to maintain proper distance
from vehicles ahead.

•

The DCA system automatically deceler-
ates your vehicle to help assist the driver
to maintain a following distance from
the vehicle ahead. Manually brake when
deceleration is required to maintain a
safe distance upon sudden braking by
the vehicle ahead or when a vehicle sud-
denly appears in front of you. Always
stay alert when using the DCA system.

•

If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system. The system
will cancel with a warning chime once it
judges that the vehicle has come to a
standstill. To prevent the vehicle from
moving, the driver must depress the
brake pedal.

The DCA system is intended to assist the
driver in keeping a following distance from
the vehicle ahead traveling in the same lane
and direction.

If the radar sensor detects a slower moving
vehicle ahead, the system will reduce the ve-
hicle speed to help assist the driver to main-
tain a following distance.

The

system

automatically

controls

the

throttle and applies the brakes (up to ap-
proximately 40% of vehicle braking power) if
necessary.

The detection range of the sensor is approxi-
mately 650 ft (200m) ahead.

WARNING

Failure to follow the warnings and instruc-
tions for proper use of the DCA system
could result in serious personal injury or
death.

•

When the vehicle ahead detection indi-
cator light is not illuminated, the system
will not control the vehicle or warn the
driver.

•

Never place your foot under the brake
pedal. Your foot may be caught when the
system controls the brake.

•

Depending on the position of the accel-
erator pedal, the system may not be able
to assist the driver to release the accel-
erator pedal appropriately.

The DCA system brakes and moves the ac-
celerator pedal upward according to the dis-
tance from and the relative speed of the ve-
hicle ahead to help assist the driver in
maintaining a following distance. The system
will decelerate as necessary and if the vehicle
ahead comes to a stop, the vehicle deceler-
ates to a standstill. However, the DCA sys-
tem can only apply up to approximately 40%
of the vehicle’s total braking power. If a ve-
hicle moves into the traveling lane ahead or if
a vehicle traveling ahead rapidly decelerates,
the distance between vehicles may become
