∙ 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 Genu-
ine INFINITI wiper blades, or equivalent
wiper blades, that are specifically de-
signed 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.

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) cruisecontrol mode, a warning chime does not
sound to warn you if you are too close to
the vehicle ahead, as neither the presence
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 ve- hicle at a set speed
– In heavy traffic or in traffic that varies 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 con- trol and result in an accident.

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
closer because the DCA system cannot de-
celerate the vehicle quickly enough. If this
occurs, the DCA system will sound a warning
chime and blink the system display to notify
the driver to take necessary action. For addi-
tional information, refer to “Approach warn-
ing” in this section.The DCA system helps assist the driver to
keep a following distance to the vehicle
ahead by braking and moving the accelerator
pedal upward in the normal driving condition.
When a vehicle is detected ahead:
The vehicle ahead detection indicator comes
on.When vehicle approaches a vehicle ahead:
∙ If the driver’s foot is not on the accelera- tor pedal, the system activates the brakes
to decelerate smoothly as necessary. If
the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system.
∙ If the driver’s foot is on the accelerator pedal, the system moves the accelerator
pedal upward to assist the driver to re-
lease the accelerator pedal.
When brake operation by driver is required:
The system alerts the driver by a warning
chime and blinking the vehicle ahead detec-
tion indicator. If the driver’s foot is on the
accelerator pedal after the warning, the sys-
tem moves the accelerator pedal upward to
assist the driver to switch to the brake pedal.
NOTE: ∙ The stop lights of the vehicle come on
when braking is performed by the DCA
system.
∙ When the brake operates, a noise may be
heard. This is not a malfunction.

Starting and driving5-141

Overriding the system:
The following driver’s operations override the
system operation:∙ When the driver depresses the accelera- tor pedal even further while the system is
moving the accelerator pedal upward,
the DCA system control of the accelera-
tor pedal is canceled.
∙ When the driver’s foot is on the accelera- tor pedal, the brake control by the system
is not operated.
∙ When the driver’s foot is on the brake pedal, neither the brake control nor the
alert by the system operates.
∙ When the ICC system is set, the DCA system will be canceled.Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that ve-
hicle or if another vehicle cuts in, the system
warns the driver with the chime and DCA
system display. Decelerate by depressing the
brake pedal to maintain a safe vehicle dis-
tance if:
∙ The chime sounds.
∙ The vehicle ahead detection indicator blinks.
The warning chime may not sound in some
cases when there is a short distance between
vehicles. Some examples are: ∙ When the vehicles are traveling at the same speed and the distance between
vehicles is not changing
∙ When the vehicle ahead is traveling faster and the distance between vehicles
is increasing
∙ When a vehicle cuts in near your vehicle
The warning chime will not sound when your
vehicle approaches vehicles that are parked
or moving slowly. NOTE:
The approach warning chime may sound and
the system display may blink when the radar
sensor detects objects on the side of the
road. This may cause the DCA system to de-
celerate or accelerate the vehicle. The radar
sensor may detect these objects when the
vehicle is driven on winding roads, narrow
roads, hilly roads or when entering or exiting
a curve. In these cases you will have to manu-
ally control the proper distance ahead of
your vehicle.
Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driv-
ing position in the lane) or traffic or vehicle
condition (for example, if a vehicle is being
driven with some damage).

WARNING
∙ Do not drive beyond the performance ca-pability of the tires. Accelerating quickly,
sharp steering maneuvers or sudden
braking may cause loss of control, even
with Intelligent AWD engaged.
∙ For AWD equipped vehicles, do not at- tempt to raise two wheels off the ground
and shift the transmission to any drive or
reverse position with the engine running.
Doing so may result in drivetrain damage
or unexpected vehicle movement which
could result in serious personal injury or
vehicle damage.
∙ Do not attempt to test an AWD equipped vehicle on a 2-wheel dynamometer (such
as the dynamometers used by some
states for emissions testing) or similar
equipment even if the other two wheels
are raised off the ground. Make sure that
you inform the test facility personnel
that your vehicle is equipped with AWD
before it is placed on a dynamometer. Us-
ing the wrong test equipment may result
in drivetrain damage or unexpected ve-
hicle movement which could result in se-
rious personal injury or vehicle damage.
CAUTION
∙ Do not operate the engine on a free rollerwhen any of the wheels are raised.
∙ If you use the free roller, rotate four wheels with the same speed without rais-
ing any wheels.
∙ If an AWD warning message is displayed while driving there may be a malfunction
in the AWD system. Reduce the vehicle
speed immediately and have your vehicle
checked as soon as possible. It is recom-
mended that you visit an INFINITI re-
tailer for this service.
∙ The powertrain may be damaged if you continue driving when the AWD tem-
perature or tire size incorrect messages
are displayed.
∙ If the AWD high temperature message is displayed while you are driving, pull off
the road in a safe area, and idle the en-
gine. The driving mode will change to
2WD to prevent the AWD system from
malfunctioning. If the warning message
turns off, you can drive again. ∙ If the tire size incorrect message is dis-
played while you are driving, pull off the
road in a safe area with the engine idling.
Check that all tire sizes are the same, that
the tire pressure is correct and that the
tires are not excessively worn.
∙ If a warning message continues to be dis- played after the above operations, have
your vehicle checked as soon as possible.
It is recommended that you visit an
INFINITI retailer for this service.
