Sensor maintenance
How to handle the sensor:
The sensor for the DCA system is common
with Intelligent Cruise Control and is
located below the front bumper.
To handle the sensor, see“Intelligent
Cruise Control (ICC) system” earlier in this
section. The Forward Collision Warning (FCW) sys-
tem will warn the driver by a warning light
and chime when your vehicle is getting
close to the vehicle ahead in the traveling
lane.
The FCW system will function when your
vehicle is driven at speeds of approxi-
mately 10 MPH (15 km/h) and above.

FORWARD COLLISION WARNING (FCW)
SYSTEM (if so equipped)

The FCW system uses the distance sensor
*Alocated below 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
travel lane, the vehicle ahead detection
indicator blinks and a warning chime
sounds.
PRECAUTIONS ON FCW SYSTEM
WARNING
. The FCW system is intended to warn you
before a collision but will not avoid a
collision. It is the driver’s responsibility
to stay alert, drive safely and be in
control of the vehicle at all times.
. As there is a performance limit, the
system may not provide a warning in
certain conditions.
. The system will not detect the following
objects:
—Pedestrians, animals or obstacles in
the roadway
—Oncoming vehicles in the same lane
. The system will not detect another
vehicle under the following conditions:
—When the sensor gets dirty and it is
impossible to detect the distance
from the vehicle ahead.
—When driving into a strong light (forexample, sunlight)
. The sensor generally detects the signals
returned from the reflectors on a vehicle
ahead. Therefore, the system may not
function properly under the following
conditions:
—When the reflectors of the vehicle
ahead are positioned high or close to
each other (including a small vehicle
such as motorcycles).
—When the sensor gets dirty or it isimpossible to detect the distance
from the vehicle ahead.
—When the reflectors on the vehicle
ahead are missing, damaged or
covered.
—When the reflectors of the vehicleahead are covered with dirt, snow or
road spray.
—When visibility is low (such as rain,fog, snow, etc.).
—When snow or road spray fromtraveling vehicles is splashed.
—When dense exhaust or other smoke (black smoke) from vehicles reduces
the visibility of the sensor.
—When excessively heavy baggage is
loaded in the rear seat or the
luggage room of your vehicle.
—When abruptly accelerating or de-celerating.
—On a steep downhill slope or onroads with sharp curves.
—When there is a highly reflectiveobject near the vehicle ahead (for
example, 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
objects such as reflectors, signs, white
markers, 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 extre-
mely close.
. The system is designed to automatically
check the sensor’s functionality. If the
sensor is covered with ice, a transparent
or translucent plastic bag, etc., the
system may not detect them. In these
instances the system may not be able to
warn the driver properly. Be sure to
check and clean the sensor 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 OFF
indicator light will illuminate under the
following conditions:
—When the sensor window is dirty
—When the system malfunctions
SSD1050
If the IBA OFF indicator light*Ailluminates
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
window is dirty. If the sensor window is
dirty, clean it with a soft cloth and restart
the engine. If the sensor window is not
dirty, restart the engine. If the IBA OFF
indicator light continues to illuminate even
if the IBA system is turned on with the IBA
OFF switch
*B, have the system checked
by an INFINITI retailer.
To turn on the IBA system, see “Intelligent
Cruise Control (ICC) system” later in this
section.

FCW system operation
The warning systems switch is used to turn
on and off the FCW system when it is
activated using the settings menu on the
center display. See“How to enable/disable
the FCW system using the settings menu”
later in this section.
When the warning systems switch is turned
off, the indicator
*1on the switch is off.
The indicator will also be off if the FCW, the
Lane Departure Warning (LDW) and the
Blind Spot Warning (BSW) systems are
deactivated.

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
collision cannot be prevented.
The IBA system will function when your
vehicle is driven at speeds of approxi-
mately 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.

CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to obtain
maximum engine performance and ensure
the future reliability and economy of your
new vehicle.
Failure to follow these recommendations
may result in shortened engine life and
reduced engine performance.
. Avoid driving for long periods at con-
stant speed, either fast or slow. Do not
run the engine over 4,000 rpm.
. Do not accelerate at full throttle in any
gear.
. Avoid quick starts.
. Avoid hard braking as much as possi-
ble.
. Do not tow a trailer for the first 500
miles (805 km). 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 andbrake application whenever possi-
ble.
.Maintain constant speed while com-muting and coast whenever possi-
ble.
2. Maintain constant speed.
.Look ahead to try and anticipate and minimize stops.
.Synchronizing your speed with traf-fic lights allows you to reduce your
number of stops.
.Maintaining a steady speed can
minimize red light stops and im-
prove fuel efficiency.
3. Use air conditioning (A/C) at higher vehicle speeds.
.Below 40 MPH (64 km/h), it is moreefficient to open windows to cool the
vehicle due to reduced engine load.
.Above 40 MPH (64 km/h), it is moreefficient to use A/C to cool the
vehicle due to increased aerody-
BREAK-IN SCHEDULE FUEL EFFICIENT DRIVING TIPS

namic drag..Recirculating the cool air in the cabinwhen the A/C is on reduces cooling
load.
4. Drive at economical speeds and dis- tances.
.Observing the speed limit and not
exceeding 60 MPH (97 km/h) (where
legally allowed) can improve fuel
efficiency due to reduced aerody-
namic drag.
.Maintaining a safe following dis-tance behind other vehicles reduces
unnecessary braking.
.Safely monitoring traffic to antici- pate changes in speed permits
reduced braking and smooth accel-
eration changes.
.Select a gear range suitable to road
conditions.
5. Use cruise control.
.Using cruise control during highway driving helps maintain a steady
speed.
.Cruise control is particularly effec-tive in providing fuel savings when
driving on flat terrains. 6. Plan for the shortest route.
.Utilize a map or navigation system to
determine 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 cruis-
ing 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 than30 seconds of idling at start-up to
effectively circulate the engine oil
before driving.
.Your vehicle will reach its ideal
operating temperature more quickly
while driving versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered
parking area or in the shade when-
ever possible.
.When entering a hot vehicle, open- ing the windows will help to reduce
the inside temperature faster, result-
ing in reduced demand on your A/C
system.
