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 brak-
ing by the vehicle ahead or when a vehicle
suddenly appears in front of you. Always
stay alert when using the DCA system.
The DCA system helps assist the driver to keep a
following distance to the vehicle ahead by brak-
ing 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.

●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 malfunctions
If the system cancels and a message appears
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.
FCW SYSTEM OPERATION
The FCW system is active at speeds of approxi-
mately 10 MPH (15 km/h) and above, when the
system turns on.
The warning systems switch is used to turn on
and off the FCW system when it is activated
using the settings menu on the information dis-
play. For additional information, refer to “How to
enable/disable the FCW system” using the set-
tings menu in this section.

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 mi
(805 km) . Your engine, axle or other parts
could be damaged.
BREAK-IN SCHEDULE
5-88Starting 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 effi-
ciency.
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

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 all the wheels in correct alignment.
Improper alignment increases tire wear and
lowers fuel economy.
● Use the recommended viscosity engine oil.
For additional information, refer to “Engine
oil and oil filter recommendations” in the
“Technical and consumer information” sec-
tion of 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 2-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 drive beyond the performance
capability of the tires. Accelerating
quickly, sharp steering maneuvers or
sudden braking may cause loss of con-
trol, even with Intelligent AWD
engaged.
● For AWD equipped vehicles, do not at-
tempt to raise 2 wheels off the ground
and shift the transmission to any drive
or reverse position with the engine run-
ning. Doing so may result in drivetrain
damage or unexpected vehicle move-
ment which could result in serious per-
sonal injury or vehicle damage.
●
Do not attempt to test an AWD equipped
vehicle on a 2-wheel dynamometer (such
as the dynamometers used by some
states for emissions testing) or similar
equipment even if the other 2 wheels are
raised off the ground. Make sure that you
inform the test facility personnel that
your vehicle is equipped with AWD be-
fore it is placed on a dynamometer. Using
the wrong test equipment may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
personal injury or vehicle damage.
CAUTION
● Do not operate the engine on a free
roller when any of the wheels are
raised.
● If you use the free roller, rotate 4 wheels
with the same speed without raising
any wheels.
● If an AWD warning message is dis-
played while driving there may be a
malfunction in the AWD system. Reduce
the vehicle speed immediately and have
your vehicle checked by an INFINITI re-
tailer as soon as possible.
● The powertrain may be damaged if you
continue driving when the AWD tem-
perature or tire size incorrect messages
are displayed
● If the AWD high temperature message
is displayed while you are driving, pull
off the road in a safe area, and idle the
engine. The driving mode will change to
2WD to prevent the AWD system from
malfunctioning. If the warning message
turns off, you can drive again. ●
If the tire size incorrect message is dis-
played while you are driving, 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 a warning message continues to be
displayed after the above operations,
have your vehicle checked by an
INFINITI retailer as soon as possible.
5-92Starting and driving

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 temperature of 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 light
PS
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, refer to “Power steer-
ing warning light” in the “Instruments and con-
trols” section of this manual. The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two 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.
