Failure to follow the warnings and instruc-
tions for proper use of the ProPILOT Assist
system could result in serious injury or
death.
• ProPILOT Assist is not a self-driving
system. Within the limits of its capabili-
ties, as described in this manual, it helps
the driver with certain driving activities.
• The ProPILOT Assist system is not a re-
placement for proper driving procedures
and is not designed to correct careless,
inattentive or absent-minded driving.
ProPILOT Assist will not always steer
the vehicle to keep it in the lane. The Pro-
PILOT Assist system 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.
• There are limitations to the ProPILOT
Assist system capability. The ProPILOT
Assist system does not function in all
driving, traffic, weather, and road condi-
tions. 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. •
The ProPILOT Assist system is only an
aid to assist the driver and is not a colli-
sion warning or avoidance device.
• The ProPILOT Assist system is for high-
way use only and is not intended for city
driving. Failure to apply the brakes or
steer the vehicle when necessary may re-
sult in a serious accident.
• Always observe posted speed limits and
do not set the speed over them.
• Never take your hands off the steering
wheel when driving. Always keep your
hands on the steering wheel and drive
your vehicle safely.
• Never unfasten your safety belt when
using ProPILOT Assist. Doing so auto-
matically cancels the ProPILOT Assist
system.
• The ProPILOT Assist system does not
react to stationary and slow moving
vehicles.

INTELLIGENT CRUISE CONTROL
(ICC) (for vehicles with ProPILOT
Assist)
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the ICC system
could result in serious injury or death.
• The ICC system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is recommended for
highway use only and it is not intended
for city driving. It is the driver’s respon-
sibility to stay alert, drive safely, and be
in control of the vehicle at all times. •
There are limitations to the ICC system
capability. The ICC system does not
function in all driving, traffic, weather,
and road conditions. It is the driver’s re-
sponsibility to stay alert, drive safely,
keep the vehicle in the traveling lane, and
be in control of the vehicle at all times.
• Always observe posted speed limits and
do not set the speed over them.
• 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

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
Assist. 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 Steering Assist except in appro-
priate 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
vehicles with ProPILOT Assist)” (P. 5-84).
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 vehicle 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
assist function is disabled after the wiper
operates for approximately 10 seconds).
Starting and driving5-95

Hands on detection
When the Steering Assist is activated, it moni-
tors 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 Pro-
PILOT 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
operating 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.

OC:
Turn the wheels toward the side of the
road so the vehicle will move away from
the center of the road if it moves.
4. Place the ignition switch in the LOCK position.ELECTRIC POWER STEERING
TYPE
WARNING
• If the engine is not running or is turned
off while driving, the power assist for the
steering will not work. Steering will be
harder to operate.
• When the power steering warning light
illuminates with the engine running,
there will be no power assist for the
steering. You will still have control of the
vehicle, but the steering will be harder to
operate. Have the power steering sys-
tem checked. It is recommended that you
visit an INFINITI retailer for this service.
The power steering system is designed to
provide power assist while driving to operate
the steering wheel with light force.
When the steering wheel is operated repeat-
edly or continuously while parking or driving
at a very low speed, the power assist for the
steering wheel will be reduced. This is to pre-
vent overheating of the power steering sys-
tem and protect it from getting damaged. While the power assist is reduced, steering
wheel operation will become heavy. When
the temperature of the power steering sys-
tem goes down, the power assist level will
return to normal. Avoid repeating such steer-
ing wheel operations that could cause the
power steering system to overheat.
You may hear a sound when the steering
wheel is operated quickly. However, this is
not a malfunction.
If the power steering warning light illumi-
nates while the engine is running, it may indi-
cate the power steering system is not func-
tioning properly and may need servicing.
Have the power steering system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.
When the power steering warning light illu-
minates with the engine running, there will be
no power assist for the steering, but you will
still have control of the vehicle. At this time,
greater steering effort is required to operate
the steering wheel, especially in sharp turns
and at low speeds.
For additional information, see “Power steer-
ing warning light” (P. 2-16).
