When driving on some roads, such as winding,
hilly, curved, narrow roads, or roads which are
under construction, the sensor may detect ve-
hicles 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 affected by
vehicle operation (steering maneuver or traveling
position in the lane, etc.) or vehicle condition.If
this occurs, the 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.DCA system display and indicators
The display is located between the speedometer
and tachometer.

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 DCA system display.
Decelerate by depressing the brake pedal to
maintain a safe vehicle distance 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 in-
creasing
● 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 ICC
sensor detects vehicles in other lanes
Aor
objects on the side of the road
A. This may
cause the DCA system to operate inappro-
priately. The ICC sensor may detect these
objects when the vehicle is driven on wind-
ing roads, narrow roads, hilly roads or when
entering or exiting a curve. In these cases
you will have to manually control the
proper distance ahead of your vehicle. Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driving
position in the lane) or traffic or vehicle condition
(for example, if a vehicle is being driven with some
damage) .

The Intelligent Brake Assist (IBA) system warns
the driver by a warning light and chime when
there is a risk of a collision with the vehicle ahead
in the traveling lane and the driver must take
avoidance action immediately. The system helps
reduce the rear-end collision speed by applying
the brakes when the system judges that the col-
lision cannot be prevented.
The IBA system will function when your vehicle is
driven at speeds of approximately 10 MPH
(15 km/h) and above, and when your vehicle is
driven at speeds approximately 10 MPH
(15 km/h) faster than the vehicle ahead.The IBA system uses a distance sensor
Alo-
cated behind the front bumper to measure the
distance to the vehicle ahead. When the system
judges that your vehicle is getting close to the
vehicle ahead in the traveling lane, the vehicle
ahead detection indicator light on the information
display blinks and a warning chime sounds.
The IBA system can be turned on/off by in the
settings of the vehicle information display. For
additional information, refer to “Driving aids” in
the “Instrument and controls” section of this
manual.PRECAUTIONS ON IBA SYSTEM
WARNING
● The IBA system is not a collision avoid-
ance system. It is the driver’s responsi-
bility to stay alert, drive safely and be in
control of the vehicle at all times.
● As there is a performance limit, the sys-
tem may not provide a warning or brak-
ing in certain conditions.
● The system will not detect the following
objects:
LSD2098SSD0749
INTELLIGENT BRAKE ASSIST (IBA)
SYSTEM (if so equipped)
5-88Starting and driving
●The system is designed to automatically
check the sensor’s functionality. When
the sensor detects an obstruction of the
radar signals due to dirt, adhesive ma-
terial, or similar objects to the front
bumper, the system will automatically
cancel. However, sensor may not detect
all obstructive material. In these in-
stances the system 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 the IBA
warning light will illuminate under the
following conditions:
– When the sensor area of the front bumper is dirty
– When the system malfunctions If the IBA OFF indicator light illuminates 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 dirty.
If the sensor area of the front bumper is dirty,
clean it with a soft cloth and restart the engine. If
the sensor area of the front bumper is not dirty,
restart the engine. If the IBA OFF indicator light
continues to illuminate even if the IBA system is
turned on, have the system checked by an
INFINITI retailer.
IBA SYSTEM OPERATION
The IBA system will function when your vehicle is
driven at speeds of approximately 10 MPH
(15 km/h) or above, and when the vehicle’s
speed is approximately 10 MPH (15 km/h) faster
than that of the vehicle ahead.
To turn the system on/off:

5-90Starting and driving
●Frequent short-distance driving can re-
duce fuel economy
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
● Park your vehicle in moderate ambient
temperatures when possible
10. Keeping your Vehicle Cool
● Park your vehicle in a covered parking
area or in the shade whenever possible
● When entering a hot vehicle, opening the
windows will help to reduce the inside
temperature faster, resulting in reduced
demand on your A/C system
11. Cargo
● Avoid transporting unnecessary luggage
in the vehicle
● Avoid carrying luggage in the roof rack
which can increase aerodynamic drag
12. Break-in
● Your vehicle may need a break-in period
for more than 4,000 miles to improve the
fuel economy ●
Avoid measuring fuel economy within ini-
tial 1,200 miles
13. Use D (Drive)
● Avoid using the Manual Shift mode and
selecting the Sports mode whenever
possible
NOTE:
In order to display the correct fuel
economy, reset the fuel economy meter
first.
