vehicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing circumstances in order to main-
tain a safe distance between vehicles.
. Always pay attention to the opera-
tion of the vehicle and be ready to
manually decelerate to maintain the
proper following distance. The DCA
system may not be able to decelerate
the vehicle under some circum-
stances.
. This system only brakes and moves
the accelerator pedal upward to help
assist the driver to maintain a follow-
ing 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.
. The DCA system automatically de-
celerates 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.
. If the vehicle ahead comes to a stop,
the vehicle decelerates to a standstill
within the limitations of the system.
The system will cancel with a warning
chime once it judges that the vehicle
has come to a standstill. To prevent
the vehicle from moving, the driver
must depress the brake pedal.

The DCA system is intended to assist the
driver in keeping a following distance from
the vehicle ahead traveling in the same lane
and direction.
If the radar sensor
detects 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 throt-
tle and applies the brakes (up to approxi-
mately 40% of vehicle braking power) if
necessary.
The detection range of the sensor is approxi-
mately 650 ft (200 m) ahead.

DCA SYSTEM OPERATION
WARNING
Failure to follow the warnings and
instructions for proper use of the DCA
system could result in serious personal
injury or death.
.When the vehicle ahead detection
indicator light is not illuminated,
system will not control the vehicle
or warn the driver.
. Never place your foot under the
brake pedal. Your foot may be caught
when the system controls the brake.
. Depending on the position of the
accelerator pedal, the system may
not be able to assist the driver to
release the accelerator pedal appro-
priately.
The 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 in
maintaining a following distance. The sys-
tem will decelerate as necessary and if the
vehicle ahead comes to a stop, the vehicle
decelerates to a standstill. However, the
DCA system can only apply up to approxi-

mately 40% of the vehicle’s total braking
power. If a vehicle 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 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” (P.5-92).

The DCA system helps assist the driver to
keep a following distance to the vehicle
ahead by braking and moving the accelera-
tor pedal upward in the normal driving
condition.
When a vehicle ahead is detected:
The vehicle ahead detection indicator comes
on.
When the vehicle approaches a vehicle
ahead:
. If the driver’s foot is not on the accel-
erator pedal, the system activates the brakes to decelerate smoothly as neces-
sary. If the vehicle ahead comes to a
stop, the vehicle decelerates to a stand-
still 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
release the accelerator pedal.
When brake operation by the 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
system 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.
Overriding the system:
The following driver’s operation overrides
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 accel-
erator pedal is canceled.
. When the driver’s foot is on the accel-
erator 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 (ICC)
system is set, the DCA system will be
cancelled.
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 depres-
sing 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 be-
tween 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 vehicle or on the side of the road. This
may cause the DCA system to decelerate 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 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).

FEB SYSTEM OPERATION
The FEB system operates at speeds above
approximately 3 MPH (5 km/h).
If a risk of a forward collision is detected, the
FEB system will provide the first warning to
the driver by blinking the vehicle ahead
detection indicator in the vehicle information
display and providing an audible warning. In
addition, the FEB system pushes the accel-
erator pedal up. If the driver releases the
accelerator pedal, then the system applies
partial braking.
If the driver applies the brakes quickly and
forcefully after the warning, and the FEB
system detects that there is still the possi-
bility of a forward collision, the system will
automatically increase the braking force.
If a forward collision is imminent and the
driver does not take action, the FEB system
issues the second visual (flashing) and
audible warning and automatically applies
harder braking.
NOTE:
The vehicle’s stop lights come on when
braking is performed by the FEB system.
Depending on vehicle speed and distance to
the vehicle ahead, as well as driving and
roadway conditions, the system may help
the driver avoid a forward collision or may
help mitigate the consequences of a collisionshould one be unavoidable.
If the driver is handling the steering wheel,
accelerating or braking, the FEB system will
function later or will not function.
The automatic braking will cease under the
following conditions:
.
When the steering wheel is turned as far
as necessary to avoid a collision.
. When the accelerator pedal is depressed.
. When there is no longer a vehicle de-
tected ahead.
If the FEB system has stopped the vehicle,
the vehicle will remain at a standstill for
approximately 2 seconds before the brakes
are released.

CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to obtain
maximum engine performance and en-
sure 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 constant
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 possible. 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 possible.
.Maintain constant speed while com-muting and coast whenever possible.
2. Maintain constant speed.
.Look ahead to try and anticipate and minimize stops.
.Synchronizing your speed with traffic
lights allows you to reduce your
number of stops.
.Maintaining a steady speed can mini-mize 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 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 aerodynamic
drag.
.Recirculating the cool air in the cabinwhen the A/C is on reduces cooling
load.
BREAK-IN SCHEDULE FUEL EFFICIENT DRIVING TIPS

4. Drive at economical speeds and dis-tances.
.Observing the speed limit and notexceeding 60 MPH (97 km/h) (where
legally allowed) can improve fuel
efficiency due to reduced aerody-
namic drag.
.Maintaining a safe following distance
behind other vehicles reduces unne-
cessary braking.
.Safely monitoring traffic to anticipatechanges in speed permits reduced
braking and smooth acceleration
changes.
.Select a gear range suitable to roadconditions.
5. Use cruise control.
.Using cruise control during highway driving helps maintain a steady speed.
.Cruise control is particularly effectivein 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 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 than30 seconds of idling at start-up to
effectively circulate the engine oil
before driving.
.Your vehicle will reach its ideal oper-ating temperature more quickly while
driving versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered parking area or in the shade whenever possi-
ble.
.When entering a hot vehicle, openingthe windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system. .
Keep your engine tuned up.
. Follow the recommended scheduled
maintenance.
. Keep the tires inflated to the correct
pressure. Low tire pressure increases tire
wear and lowers fuel economy.
. Keep the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
. Use the recommended viscosity engine
oil. (See “Engine oil and oil filter recom-
mendation” (P.10-9).)

The AWD warning light is located in the
meter.
The AWD warning light comes on when the
ignition switch is pushed to the ON position.
It turns off soon after the engine is started.
If any malfunction occurs in the Intelligent
AWD system while the engine is running, thewarning light will come on.
The warning light may blink rapidly (about
twice per second) while trying to free a stuck
vehicle due to high power train oil tempera-
ture. The driving mode may change to two-
wheel drive. If the warning light blinks
rapidly during operation, stop the vehicle
with the engine idling in a safe place
immediately. Then if the light goes off after
a while, you can continue driving.
A large difference between the diameters of
front and rear wheels will make the warning
light blink slowly (about once per two
seconds). Pull off the road in a safe area,
and idle the engine. Check that all tire sizes
are the same, tire pressure is correct and
tires are not worn.
If the warning light is blinking after the
above operation, have your vehicle checked
as soon as possible. It is recommended you
visit an INFINITI retailer for this service.WARNING
.
For AWD equipped vehicles, do not
attempt 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 vehicle damage or personal
injury.
. Do not attempt to test an AWD
equipped vehicle on a 2-wheel dy-
namometer (such as the dynam-
ometers used by some states for
emissions testing) or similar equip-
ment 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 dynam-
ometer. Using the wrong test equip-
ment may result in drivetrain damage
or unexpected vehicle movement
which could result in serious vehicle
damage or personal injury.
CAUTION
.Do not operate the engine on a free
roller when any of the wheels are
raised.
. If the warning light comes on while
driving there may be a malfunction in
the AWD system. Reduce the vehicle
speed and have your vehicle checked
as soon as possible. It is recom-
mended you visit an INFINITI retailer
for this service.
