System operation
WARNING
Normally when controlling the distance to
a vehicle ahead, this system automatically
accelerates or decelerates your vehicle
according to the speed of the vehicle
ahead. Depress the accelerator to prop-
erly accelerate your vehicle when accel-
eration is required for a lane change. De-
press the brake pedal when deceleration
is required to maintain a safe distance to
the vehicle ahead due to its sudden brak-
ing or if a vehicle cuts in. Always stay alert
when using the ICC system.
The driver sets the desired vehicle speed based
on the road conditions. The ICC system main-
tains the set vehicle speed, similar to standard
cruise control, as long as no vehicle is detected in
the lane ahead.
The ICC system displays the set speed.
Vehicle detected ahead:
When a vehicle is detected in the lane ahead, the
ICC system decelerates the vehicle by control-
ling the throttle and applying the brakes to match
the speed of a slower vehicle ahead. The system then controls the vehicle speed based on the
speed of the vehicle ahead to maintain the driver
selected distance.
The stoplights of the vehicle come on when
breaking is performed by the ICC system.
When the brake operates, a noise may be
heard. This is not a malfunction.
When a vehicle ahead is detected, the vehicle
ahead detection indicator comes on. The ICC
system will also display the set speed and se-
lected distance.
Vehicle ahead not detected:
When a vehicle is no longer detected ahead, the
ICC system gradually accelerates your vehicle to
resume the previously set vehicle speed. The ICC
system then maintains the set speed.
When a vehicle is no longer detected the vehicle
ahead detection indicator turns off.
If a vehicle ahead appears during acceleration to
the set vehicle speed or any time the ICC system
is in operation, the system controls the distance
to that vehicle.
When a vehicle is no longer detected under
approximately 15 MPH (24 km/h), the system will
be canceled.
When passing another vehicle,
the set speed
indicator
Bwill flash when the vehicle speed
exceeds the set speed. The vehicle detect indi-
cator will turn off when the area ahead of the
vehicle is open. When the pedal is released, the
vehicle will return to the previously set speed.
Even though your vehicle speed is set in the ICC
system, you can depress the accelerator pedal
when it is necessary to accelerate your vehicle
rapidly.

● The distance to the vehicle ahead will
change according to the vehicle speed. The
higher the vehicle speed, the longer the dis-
tance.
● If the engine is stopped, the set distance
becomes “long”. (Each time the engine is
started, the initial setting becomes “long”.)
Approach warning
If your vehicle comes closer to the vehicle ahead
due to rapid deceleration of that vehicle or if
another vehicle cuts in, the system warns the
driver with the chime and ICC system display.
Decelerate by depressing the brake pedal to
maintain a safe vehicle distance if:
● The chime sounds.
● The vehicle ahead detection indicator blinks
in orange.
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 in-
creasing
● When a vehicle cuts in near your vehicle
The warning chime will not sound when: ● The vehicle approaches other vehicles that
are parked or moving slowly.
● The accelerator pedal is depressed, overrid-
ing the system. NOTE:
The approach warning chime may sound
and the system display may blink when the
ICC sensor detects objects on the side of
the vehicle
Aor on the side of the roadA.
This may cause the ICC system to deceler-
ate or accelerate the vehicle. The ICC sen-
sor may detect these objects when the ve-
hicle is driven on winding roads, narrow
roads, hilly roads, or when entering or exit-
ing a curve. In these cases you will have to
manually control the proper distance
ahead of your vehicle.

PREVIEW FUNCTION (for Intelligent
Cruise Control system equipped
models)
The ICC system with the preview function iden-
tifies the need to apply emergency braking by
sensing the vehicle ahead in the same lane and
the distance to the vehicle ahead and relative
speed from it, it applies the brake pre-pressure
before the driver depresses the brake pedal and
helps improve brake response by reducing pedal
free play.
For more details, see “Brake assist” in this sec-
tion.The Distance Control Assist (DCA) system
brakes and moves the accelerator pedal upward
according to the distance from and the relative
speed of the vehicle ahead to help assist the
driver to maintain a following distance.
WARNING
●
Always drive carefully and attentively
when using the Distance Control Assist
system. Read and understand the Own-
er’s Manual thoroughly before using
the DCA system. To avoid serious injury
or death, do not rely on the system to
prevent accidents or to control the ve-
hicle’s speed in emergency situations.
Do not use the Distance Control Assist
system except in appropriate road and
traffic conditions.
● If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill
within the limitations of the system. The
system will cancel once it judges that
the vehicle has come to a standstill with
a warning chime. To prevent the vehicle
from moving, the driver must depress
the brake pedal.
● The DCA system will not apply brake
control while the driver’s foot is on the
accelerator pedal.
PRECAUTIONS ON DISTANCE
CONTROL ASSIST SYSTEM
The system is intended to assist the driver to
keep a following distance from the vehicle ahead
traveling in the same lane and direction.
The distance sensor is located behind the front
bumper
A. If the distance sensorAdetects a
slower moving vehicle ahead, the system will
reduce the vehicle speed to help assist the driver
to maintain a following distance.
The system automatically controls the throttle
and applies the brakes (up to 25% of vehicle
braking power) if necessary.

5-68Starting and driving

DISTANCE CONTROL ASSIST
OPERATION
Always pay attention to the operation of the ve-
hicle and be ready to manually decelerate to
maintain the proper following distance. The Dis-
tance Control Assist (DCA) system may not be
able to decelerate the vehicle under some cir-
cumstances.
The DCA system uses a sensor
Alocated be-
hind the front bumper of the vehicle to detect
vehicles traveling ahead. The sensor generally
detects the signals returned from the vehicle ahead. Therefore, if the sensor cannot detect the
reflection from the vehicle ahead, the DCA sys-
tem may not operate.
The following are some conditions in which the
sensor cannot detect the signals:
● When the reflector of the vehicle ahead is
covered with dirt, snow and road spray
● When dense exhaust or other smoke (black
smoke) from vehicles reduces the sensor’s
visibility
● When excessively heavy baggage is loaded
in the rear seat or the luggage room of your
vehicle
The DCA system is designed to automatically
check the sensor’s operation. When the front
bumper area of the distance sensor is covered
with dirt or is obstructed, the system will auto-
matically cancel. If the front bumper area of the
distance sensor is covered with ice, a transparent
or translucent vinyl bag, etc., the DCA system
may not detect them. In these instances, the
vehicle-to-vehicle distance control mode may not
cancel and may not be able to maintain the se-
lected following distance from the vehicle ahead.
Be sure to check and clean the front bumper area
of the distance sensor regularly. The DCA system is designed to help assist the
driver to maintain a following distance from the
vehicle ahead. The system will decelerate as nec-
essary and if the vehicle ahead comes to a stop,
the vehicle decelerates to a standstill. However,
the DCA system can only apply up to 25% of the
vehicles total braking power. If a vehicle moves
into the traveling lane ahead or if a vehicle travel-
ing ahead rapidly decelerates, the distance be-
tween vehicles may become closer because the
DCA system cannot decelerate 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.
See “Approach warning” in this section.
This system only brakes and moves the accelera-
tor pedal upward to help assist the driver to
maintain a following distance from the vehicle
ahead. Acceleration should be operated by the
driver.
The DCA system does not control vehicle speed
or warn you when you approach stationary and
slow moving vehicles. You must pay attention to
vehicle operation to maintain proper distance
from vehicles ahead.

System operation
WARNING
The Distance Control Assist system auto-
matically decelerates 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 suddenly appears in front of you.
Always stay alert when using the DCA
system.
The Distance Control Assist (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 accelerator
pedal, the system activates the brakes to
decelerate smoothly as necessary. If the ve-
hicle ahead comes to a stop, the vehicle
decelerates to a standstill within the limita-
tions of the system. ●
If the driver’s foot is on the accelerator pedal,
the system moves the accelerator pedal up-
ward to assist the driver to release the ac-
celerator pedal.
When brake operation by driver is required:
The system alerts the driver by a warning chime
and blinking the vehicle ahead detection indica-
tor. If the driver’s foot is on the accelerator pedal
after the warning, the system moves the accel-
erator pedal upward to assist the driver to switch
to the brake pedal.
The stoplights 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.
WARNING
● When the vehicle ahead detection indi-
cator light is not illuminated, the system
will not control or warn the driver.
● Depending on the position of the accel-
erator pedal, the system may not be
able to assist the driver to release the
accelerator pedal appropriately. ●
If the vehicle ahead comes to a stand-
still, the vehicle decelerates to a stand-
still within the limitations of the system.
The system will release brake control
with a warning chime once it judges the
vehicle is at a standstill. To prevent the
vehicle from moving, the driver must
depress the brake pedal. (The system
will resume control automatically once
the system reaches 3 MPH (5 km/h)) .
Overriding the system:
The following driver’s operation overrides the
system operation. ● When the driver depresses the accelerator
pedal even further while the system is mov-
ing the accelerator pedal upward, the DCA
system control of the accelerator pedal is
canceled.
● When the driver’s foot is on the accelerator
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 Intelligent Cruise Control system
is set, the DCA system will be cancelled.

– When excessively heavy baggage isloaded in the rear seat or the luggage
room of your vehicle.
– When abruptly accelerating or decelerating.
– On a steep downhill slope or on roads with sharp curves.
– When there is a highly reflective ob- ject near the vehicle ahead (for ex-
ample, being very close to another
vehicle, signboard, etc.)
– When you are towing a trailer.
● Depending on certain road conditions
(curved or beginning of a curve) , vehicle
conditions (steering position or vehicle
position) , or the preceding vehicle’s
conditions (position in lane, etc.) , the
system may not function properly. The
system may detect highly reflective ob-
jects such as signs and other stationary
objects on the road or near the traveling
lane and provide unnecessary warning.
● The system may not function in offset
conditions.
● The system may not function when the
distance to the vehicle ahead is ex-
tremely close. ●
The system is designed to automati-
cally check the sensor’s functionality. If
the sensor area of the front bumper is
covered with ice, a transparent or trans-
lucent bag, etc., the system may not
detect them. In these instances, the sys-
tem may not be able to warn the driver
properly. Be sure to check and clean the
sensor area of the front bumper
regularly.
● Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
● A sudden appearance of a vehicle in
front (for example, it abruptly cuts in)
may not be detected and the system
may not warn the driver soon enough.
● The system will be cancelled automati-
cally with a beep sound and a message
will pop up under the following
conditions:
– When the sensor area of the front bumper is dirty
– When the system malfunctions If the system cancels and a message pops up
with a beep sound, pull off the road to a safe
location, stop the vehicle and turn the engine off.
Check to see if the sensor area of the front
bumper is blocked. If the sensor area of the front
bumper is blocked, remove the object blocking
and restart the engine.
If the sensor is malfunctioning, have the system
checked by an INFINITI retailer.

BREAK-IN SCHEDULE
5-84Starting and driving

Follow these easy-to-use Fuel Efficient Driving
Tips to help you achieve the most fuel economy
from your vehicle.1. Use Smooth Accelerator and Brake
Pedal Application
● Avoid rapid starts and stops
● Use smooth, gentle accelerator and
brake application whenever possible
● Maintain constant speed while commut-
ing and coast whenever possible
2. Maintain Constant Speed
● Look ahead to try and anticipate and mini-
mize stops
● Synchronizing your speed with traffic
lights allows you to reduce your number
of stops
● Maintaining a steady speed can minimize
red light stops and improve fuel efficiency
3. Use Air Conditioning (A/C) at Higher
Vehicle Speeds
● Below 40 MPH (64 km/h), it is more
efficient to open windows to cool the
vehicle due to reduced engine load ●
Above 40 MPH (64 km/h), it is more
efficient to use A/C to cool the vehicle
due to increased aerodynamic drag
● Recirculating the cool air in the cabin
when the A/C is on reduces cooling load
4. Drive at Economical Speeds and Dis-
tances
● Observing the speed limit and not ex-
ceeding 60 MPH (97 km/h) (where le-
gally allowed) can improve fuel efficiency
due to reduced aerodynamic drag
● Maintaining a safe following distance be-
hind other vehicles reduces unnecessary
braking
● Safely monitoring traffic to anticipate
changes in speed permits reduced brak-
ing and smooth acceleration changes
● Select a gear range suitable to road con-
ditions.
5. Use Cruise Control
● Using cruise control during highway driv-
ing helps maintain a steady speed
● Cruise control is particularly effective in
providing fuel savings when driving on flat
terrains 6.
Plan for the Shortest Route
● Utilize a map or navigation system to de-
termine the best route to save time
7. Avoid Idling
● Shutting off your engine when safe for
stops exceeding 30–60 seconds saves
fuel and reduces emissions
8. Buy an Automated Pass for Toll Roads
● Automated passes permit drivers to use
special lanes to maintain cruising speed
through the toll and avoid stopping and
starting
9. Winter Warm Up
● Limit idling time to minimize impact to fuel
economy
● Vehicles typically need no more than
30 seconds of idling at start-up to effec-
tively circulate the engine oil before driv-
ing
● Your vehicle will reach its ideal operating
temperature more quickly while driving
versus idling
FUEL EFFICIENT DRIVING TIPS

If the AWD error warning message is displayed,
there may be a malfunction in the Intelligent AWD
system. Reduce vehicle speed and have your
vehicle checked by an INFINITI retailer as soon as
possible.The AWD high temperature message may be
displayed while trying to free a stuck vehicle due
to increased oil temperature. The driving mode
may change to two-wheel drive. If this message is
displayed, stop the vehicle with the engine idling,
as soon as it is safe to do so. Then if the message
turns off, you can continue driving.The tire size message may be displayed if there is
a large difference between the diameters of front

WARNING
●Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
●
Safe parking procedures require that
both the parking brake be set and the
transmission placed into P (Park) . Fail-
ure to do so could cause the vehicle to
move unexpectedly or roll away and re-
sult in an accident. Make sure the shift
selector has been pushed as far forward
as it can go and cannot be moved without
depressing the foot brake pedal.
● Never leave the engine running while
the vehicle is unattended.
● Do not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls. Unattended
children could become involved in seri-
ous accidents.
1. Firmly apply the parking brake.
2. Move the shift selector to the P (Park) posi- tion. 3. To help prevent the vehicle from rolling into
traffic when parked on an incline, it is a good
practice to turn the wheels as illustrated.
● HEADED DOWNHILL WITH CURB:
A
Turn the wheels into the curb and move the
vehicle forward until the curb side wheel
gently touches the curb.
● HEADED UPHILL WITH CURB:
B
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
● HEADED UPHILL OR DOWNHILL, NO
CURB:
C
Turn the wheels toward the side of the road
so the vehicle will move away from the cen-
ter of the road if it moves.
4. Place the ignition switch in the LOCK posi- tion.
