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 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 automatically
check the sensor’s functionality. If the
sensor area of the front bumper is cov-
ered with ice, a transparent or translu-
cent bag, etc., the system may not de-
tect them. In these instances, the
system may not be able to warn the
driver properly. Be sure to check and
clean the sensor area of the front bum-
per 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 malfunctionsIf 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.

●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 malfunctionsIf 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 bumper is not dirty, restart
the engine. If the IBA OFF indicator light contin-
ues 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:
1. Push the
button to enter the “Set-
tings” menu in the vehicle information dis-
play, then select using the ENTER button.
2. Use the
buttons to select “Driver As-
sistance”, then press the ENTER button.
3. Use the
buttons to select “Intelligent
Brake Assist”, using the ENTER button the
system can be turned On or Off.The IBA system will remain in the last ON or OFF
state it was left in until it is changed in the vehicle
information display, see “Driver Assistance” in the
“Instrument and controls” section.
Illumination of the IBA OFF indicator light without
the warning chime sound is an indication that the
IBA system is temporarily unavailable. It will occur
under the following conditions:
When the radar signal is temporarily interrupted.
The IBA OFF indicator light will turn off when the
system returns to its normal operating conditions.
For the sensor maintenance, see “Intelligent
Cruise Control (ICC) system (Full speed range)”.

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 rec-
ommendations may result in shortened
engine life and reduced engine
performance.
●Avoid driving for long periods at constant
speed, either fast or slow, and 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.
●Do not tow a trailer for the first 500 miles
(800 km) . Your engine, axle or other parts
could be damaged.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
BREAK-IN SCHEDULE FUEL EFFICIENT DRIVING TIPS

Page 430 of 547

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
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●Keep your engine tuned up.
●Follow the recommended scheduled main-
tenance.
●Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
●Keep the front 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 recommenda-
tions” in “Technical and consumer informa-
tion” later in this manual.If any malfunction occurs in the Intelligent AWD
system while the engine is running, messages are
displayed in the meter.

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
and rear wheels. 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 any warning messages continue to be dis-
played, have your vehicle checked by an INFINITI
retailer as soon as possible.

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
lever 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 lever to the P (Park) position.
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.

WARNING
●If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be harder to operate.
●When the power steering warning light
illuminates with the engine running,
there will be no power assist for the
steering. You will still have control of
the vehicle but the steering will be
harder to operate. Have the power
steering system checked by an INFINITI
retailer.
The power steering system is designed to pro-
vide power assist while driving to operate the
steering wheel with light force.
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assist for the steering
wheel will be reduced. This is to prevent over-
heating of the power steering system and protect
it from getting damaged. While the power assist
is reduced, steering wheel operation will become
heavy. If the steering wheel operation is still per-
formed, the power steering may stop and the
power steering warning light will illuminate. In a
safe location, stop the engine and push the igni-
tion switch to the OFF position. The temperatureof the power steering system will go down after a
period of time and the power assist level will
return to normal after starting the engine. The
power steering warning light will go off. Avoid
repeating such steering wheel operations that
could cause the power steering system to over-
heat.
You may hear a sound from the front of the vehicle
when the steering wheel is operated quickly. This
is a normal operational noise and is not a mal-
function.
If the electric power steering warning lightPS
illuminates while the engine is running, it may
indicate the power steering system is not func-
tioning properly and may need servicing. Have
the power steering system checked by an
INFINITI retailer.
When the electric power steering warning light
illuminates with the engine running, there will be
no power assist for the steering but you will still
have control of the vehicle. At this time, greater
steering effort is required to operate the steering
wheel, especially in sharp turns and at low
speeds.
For additional information see “Power steering
warning light” in the “Instruments and controls”
section.The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at 2 wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake pads faster, and reduce gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
POWER STEERING BRAKE SYSTEM
5-94Starting and driving
Page 435 of 547

WARNING
●While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
●If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal to
heat up the brakes. Do this until the brakes return
to normal. Avoid driving the vehicle at high
speeds until the brakes function correctly.
Parking brake break-in
Break-in the parking brake shoes whenever the
effect of the parking brake is weakened or when-
ever the parking brake shoes and/or drum/rotors
are replaced, in order to assure the best brake
performance.This procedure is described in the vehicle service
manual and can be performed by an INFINITI
retailer.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless
or dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remem-
ber that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if you
are using tire chains. Always maintain a
safe distance from the vehicle in front of
you. Ultimately, the driver is respon-
sible for safety.
●Tire type and condition may also affect
braking effectiveness.
– When replacing tires, install the
specified size of tires on all four
wheels.– When installing a spare tire, make
sure that it is the proper size and type
as specified on the Tire and Loading
Information label. See “Tire and
Loading Information label” in the
“Technical and consumer informa-
tion” section of this manual.
– For detailed information, see
“Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on slip-
pery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate to prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
Starting and driving5-95
Page 436 of 547

WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may hear
a “clunk” noise and/or feel a pulsation in the brake
pedal. This is normal and does not indicate a
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates the
ABS warning light on the instrument panel. The
brake system then operates normally, but without
anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by an INFINITI retailer.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h). The speed varies according to road
conditions.When the ABS senses that 1 or more wheels are
close to locking up, the actuator rapidly applies
and releases hydraulic pressure. This action is
similar to pumping the brakes very quickly. You
may feel a pulsation in the brake pedal and hear a
noise from under the hood or feel a vibration from
the actuator when it is operating. This is normal
and indicates that the ABS is operating properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.
BRAKE ASSIST (if so equipped)
When the force applied to the brake pedal ex-
ceeds a certain level, the brake assist is activated
generating greater braking force than a conven-
tional brake booster even with light pedal force.
WARNING
The brake assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. it is the driv-
ers responsibility to stay alert, drive safely
and be in control of the vehicle at all times.The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and ve-
hicle motion. Under certain driving conditions,
the VDC System helps to perform the following
functions:
●Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power is
transferred to a non slipping drive wheel on
the same axle.
●Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function) .
●Controls brake pressure at individual wheels
and engine output to help the driver maintain
control of the vehicle in the following condi-
tions:
– understeer (vehicle tends to not follow
the steered path despite increased steer-
ing input)
– oversteer (vehicle tends to spin due to
certain road or driving conditions)
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss of
vehicle control in all driving situations.
