Autonomous braking function
If the driver does not react to the distance
warning signal in a critical situation, the FEB
system can assist with the autonomous braking
function
The autonomous braking function can help the
driver to avoid an accident or reduces the
effects of an accident.
The autonomous braking function is available in
the following speed ranges:
•4–125 MPH (7-200 km/h) for moving vehicles
•4–30 MPH (7 -50 km/h) for stationary ve-
hicles
Adaptive brake assist function
Adaptive brake assist function provides braking
assistance in hazardous situations at speeds
above 4MPH (7 km/h). It uses radar sensor
technology to assess the traffic situation.
If the system detects a risk of collision with the
vehicle in front, it calculates the braking force
necessary to avoid a collision. If you apply the
brakes forcefully, the adaptive brake assist
function will automatically increase the braking
force to a level suitable for the traffic condi-
tions.
If the adaptive brake assist function activates,
keep the brake pedal depressed until the emer-
gency braking situation is over. ABS prevents
the wheels from locking.
The brakes will work normally again if:
•You release the brake pedal.
•There is no longer any danger of a collision.
•No obstacle is detected in front of your
vehicle.
The brake assist function is then deactivated. At high speeds, the adaptive brake assist func-
tion is capable of reacting to moving objects
that have already been detected as such at
least once over the period of observation.
Up to a speed of approximately 45 MPH (70
km/h), the adaptive brake assist function reacts
to stationary vehicles.

ACTIVE SOUND ENHANCEMENT
The active sound enhancement generates
sounds according to engine speed through the
speakers
2and woofer1(if equipped) to
enhance the quality of the engine sound. IPA is an electronic parking aid with ultrasound.
It detects vehicles and open spaces on both
sides of the vehicle. A parking symbol indicates
a suitable parking space. Active steering inter-
vention can assist you during parking and when
exiting a parking space. The driver controls the
accelerator, brake and gear shift. You may also
use the parking sensor system (see
Parking
sensor system (if equipped) later in this sec-
tion).
IMPORTANT SAFETY NOTES
WARNING
•IPA is only an aid. It is not a substitute for
your attention to the immediate surround-
ings. The responsibility for safe maneuver-
ing and parking remains with you.
•Make sure that no persons, animals or ob-
jects are in the maneuvering range
•When the parking sensor system is deacti-
vated, IPA is also unavailable.
•While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
cause you to collide with other road users.
There is a risk of an accident.
•Pay attention to other road users. Stop the
vehicle if necessary or cancel the IPA park-
ing procedure
•This system is not designed to prevent con-
tact with small or moving objects.
•If your vehicle sustains damage to the bum-
per fascia, leaving it misaligned or bent, the
sensing zone may be altered causing inac-
curate measurement of obstacles or false
alarms.
•This system is not designed to prevent con-
tact with small or moving objects.
•If your vehicle sustains damage to the bum-
per fascia, leaving it misaligned or bent, the
sensing zone may be altered causing inac-
curate measurement of obstacles or false
alarms.
CAUTION
Do not drive over obstacles such as curbs, as
you may damage the wheels or tires.
IPA may also display spaces not suitable for
parking, for example:
•Parking or stopping prohibition.

below 5 MPH (10 km/h). Otherwise, IPA will
be canceled.
7. Stop as soon as the parking sensor system sounds the continuous warning tone, if not
before. Maneuvering may be required in
tight parking spaces.
The [Park Assist active Select D Observe
surroundings] message appears in the ve-
hicle information display.
8. Select transmission position D (Drive) while the vehicle is stationary.
IPA immediately steers in the other direc-
tion.
The [Park Assist Observe surroundings] mes-
sage appears in the vehicle information dis-
play.
NOTE
You will achieve the best results by waiting
for the steering procedure to complete before
pulling away.
9. Drive forwards and be ready to brake at all times.
Maneuvering may be required in tight park-
ing spaces. Drive forward and back up as
prompted by the parking sensor system
warning displays, several times if necessary. 10. Stop as soon as the parking sensor system
sounds the continuous warning tone, if not
before.
The [Park Assist active Select R] [Observe
surroundings] message appears in the ve-
hicle information display.
As soon as the parking procedure is com-
plete the [Park Assist switched off] mes-
sage appears and a warning tone sounds.
The vehicle is now parked.
11. Before leaving the vehicle, secure the ve- hicle against rolling away unintentionally:
•The electric parking brake must be ap-
plied.
•The transmission must be in position P
(Park) and the transmission position dis-
play must show P in the vehicle informa-
tion display.
•The key must be removed from the igni-
tion switch.
•On uphill or downhill gradients, the front
wheels must be turned towards the curb.
IPA no longer supports you with steering inter-
ventions. When IPA is finished, you must steer
again yourself. The parking sensor system is
still available. Parking tips:
•The way your vehicle is positioned in the
parking space after parking is dependent on
various factors. These include the position
and shape of the vehicles parked in front and
behind it and the conditions of the location.
It may be the case that IPA guides you too far
into a parking space, or not far enough into
it. In some cases, it may also lead you across
or onto the curb. If necessary you should
cancel the parking procedure with IPA.
•During the parking maneuver, the system will
indicate when you should shift to R (Reverse)
or D (Drive). However, you can freely choose
to shift gear whenever you feel you need to.
Should the transmission change take place
too early, the parking procedure will be
canceled. A sensible parking position can no
longer be achieved from this position.
EXITING A PARKING SPACE
In order that IPA can support when exiting the
parking space:
•You need to have parked using IPA.
•The border of the parking space must be high
enough at the front and the rear. A curb
stone is too small, for example.

6.Avoid Idling
•Shutting off your engine when safe for
stops exceeding 30 seconds saves fuel
and reduces emissions.
7. 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.
8. 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 effectively
circulate the engine oil before driving.
•Your vehicle will reach its ideal operating
temperature more quickly while driving
versus idling.
9. 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 mainte-
nance.
•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, see Recom-
mended fluids/lubricants and capacities in
the 10. Technical information section
WARNING
•Do not drive beyond the performance capa-
bility of the tires, even with 4WD engaged.
Accelerating quickly, sharp steering ma-
neuvers or sudden braking may cause loss
of control.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), and tread pattern on all four wheels.
•This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy or
muddy roads that tires may get stuck in.
•For 4WD equipped vehicles, do not attempt
to raise two wheels off the ground and shift
the transmission to any drive or reverse po-
sition with the engine running. Doing so
may result in drivetrain damage or unex-
pected vehicle movement which could re-
sult in serious vehicle damage or personal
injury.
•Do not attempt to test a 4WD equipped ve-
hicle on a 2-wheel dynamometer (such as
the dynamometers used by some states for
emissions testing) or similar equipment
even if the other two wheels are raised off
the ground. Make sure that you inform the
test facility personnel that your vehicle is
INCREASING FUEL ECONOMY FOUR-WHEEL DRIVE (4WD) (IF EQUIPPED)

equipped with 4WD before it is placed on a
dynamometer. Using the wrong test equip-
ment may result in drivetrain damage or un-
expected vehicle movement which could re-
sult in serious vehicle damage or personal
injury.
•When a wheel is off the ground due to an
uneven surface, do not spin the wheel
excessively.
CAUTION
Never tow the vehicle with one axle raised. This
may damage the differential. Damage of this
sort is not covered by the warranty. All wheels
must be fully raised (seeFour-Wheel Drive
(4WD) models in the6. In case of emergency
section)
4WD, together with VDC, improves the traction
of your vehicle whenever a drive wheel spins
due to insufficient grip.
If you fail to adapt your driving style, 4WD can
neither reduce the risk of an accident nor
override the laws of physics. 4WD cannot take
account of road, weather, and traffic conditions.
4WD is only an aid. You are responsible for the
distance to the vehicle in front, for vehicle speed, for braking in good time, and for staying
in lane.
If a drive wheel spins due to insufficient grip
•When pulling away, only depress the accel-
erator pedal as far as is necessary.
•Accelerate less when driving.
NOTE
In wintry driving conditions, the maximum effec-
tiveness of 4WD can only be achieved if you use
winter tires (M+S tires), with snow chains if nec-
essary.
WARNING
•Do not stop or park the vehicle over flam-
mable 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 applied and the P
(Park) position engaged. Failure to do so
could cause the vehicle to move unexpect-
edly or roll away and result in an accident.
•When parking the vehicle, make sure the P
(Park) position is engaged. The shift lever
cannot be moved out of the P (Park) position
without depressing the brake pedal.
•Never leave the engine running while the
vehicle is unattended.
•To help avoid risk of injury or death through
unintended operation of the vehicle and/or
its systems, do not leave children, people
who require the assistance of others, or
pets unattended in your vehicle. Addition-
ally, the temperature inside a closed vehicle
on a warm day can quickly become high
enough to cause a significant risk of injury
or death to people and pets.

CAUTION
Always secure the vehicle correctly against
rolling away. Otherwise, the vehicle or its drive
train could be damaged.
To ensure that the vehicle is secured against
rolling away unintentionally:
•The electric parking brake must be applied.
•The transmission must be in position P (Park)
and the transmission position display must
show P in the vehicle information display.
•The key must be removed from the ignition
switch.
•On uphill or downhill gradients, the front
wheels must be turned towards the curb. 1. Firmly apply the parking brake.
2. Press the P (Park) button.
3. To help prevent the vehicle from moving into
traffic when parked on an incline, it is a good
practice to turn the wheels as illustrated.
HEADED DOWNHILL WITH CURB
1
Turn the wheels into the curb and move the
vehicle forward until the curb side wheel
gently touches the curb. Then apply the
parking brake.
HEADED UPHILL WITH CURB
2
Turn the wheels away from the curb and
allow the vehicle to move back until the curb
side wheel gently touches the curb. Then
apply the parking brake. HEADED UPHILL OR DOWNHILL, WITHOUT
CURB
3
Turn the wheels toward the side of the road
so the vehicle will move away from the
center of the road if the vehicle moves. Then
apply the parking brake.

CAUTION
•If wheels or tires other than INFINITI recom-
mended ones are used, the power steering
system may not operate properly and the
[Power Steering Malfunction See Operators
Manual] warning may appear in the vehicle
information display.
•Do not modify the vehicle’s suspension. If
suspension parts such as shock absorbers,
struts, springs, stabilizer bars, bushings
and wheels are not INFINITI recommended
for your vehicle or are extremely deterio-
rated, the power steering system may not
operate properly and the [Power Steering
Malfunction See Operators Manual] warn-
ing may appear in the vehicle information
display.
•Do not modify the vehicle’s steering. If
steering parts are not INFINITI recom-
mended for your vehicle or are extremely
deteriorated, the power steering system
may not operate properly and the [Power
Steering Malfunction See Operators
Manual] warning may appear in the vehicle
information display.
•Do not place the ignition switch in the on
position while the steering wheel or a tire is
removed.
•Do not turn the steering wheel as much as
possible while the ignition switch is in any
position other than the ON position.
•Installing an accessory on the steering
wheel, or changing the steering wheel, may
reduce the steering performance.
NOTE
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assistance for the steering
wheel will be reduced. This is to prevent over-
heating of the electric power steering system
and protect it from becoming damaged. While
the power assistance is reduced, steering wheel
operation will become heavy. When the tem-
perature of the electric power steering system
decreases, the power assistance level will return
to normal. Avoid repeating such steering wheel
operations that could cause the electric power
steering system to overheat. The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking ability at two wheels.BRAKE PRECAUTIONS
WARNING
While driving on a slippery surface, be careful
when braking, accelerating or downshifting.
Abrupt braking or accelerating could cause the
wheels to skid and result in an accident.
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. How-
ever, greater foot pressure on the brake pedal
will be required to stop the vehicle. The stop-
ping distance will be longer.
WARNING
•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.
•Do not coast with the engine stopped.
When the brake pedal is depressed slowly and
firmly, you may hear a clicking noise and feel a
BRAKE SYSTEM

slight pulsation. This is normal and indicates
that the Brake Assist System is operating (if
equipped).
Using brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out
the brake linings/pads faster, and increase fuel
consumption.
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.
While driving on a slippery surface, be careful
when braking, accelerating or downshifting.
Abrupt braking or acceleration could cause the
wheels to skid and result in an accident.
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 depressing the brake pedal
to heat up the brakes. Do this until the brakesreturn to normal. Avoid driving the vehicle at
high speeds until the brakes function correctly.
Driving uphill
When starting on a steep gradient, it is some-
times difficult to operate the brake. Use the
parking brake to hold the vehicle. When ready
to start, make sure that the shift lever is in an
appropriate forward or reverse driving position,
release the parking brake while depressing the
accelerator pedal. If your vehicle has an electric
parking brake, this will automatically release
when you depress the accelerator pedal (DCT
models).
Driving downhill
The engine braking action is effective for con-
trolling the vehicle while descending hills.
A low gear position in the manual shift mode,
low enough to obtain sufficient engine braking,
should be selected.
Parking brake break-in
Break in the parking brake shoes whenever the
stopping effect of the parking brake is weak-
ened or whenever the parking brake shoes
and/or drums/rotors are replaced, in order to
assure the best braking performance.
This procedure is described in the vehicle ser-
vice manual and can be performed by an
INFINITI retailer.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
The Anti-lock Braking System (ABS) is a so-
phisticated device, but it cannot prevent acci-
dents resulting from careless or dangerous
driving techniques. It can help maintain ve-
hicle control during braking on slippery sur-
faces. Remember that stopping distances on
slippery surfaces will be longer than on normal
surfaces even with ABS. Stopping distances
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 ve-
hicle in front of you. Ultimately, the driver is
responsible 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 replacement tire, make sure
that it is the proper size and type as specified
on the tire and loading information label. (See
5-88Starting and driving
Page 420 of 556
Wheels and Tiresin the9. Maintenance and
Schedules section.)
– For detailed information, see Wheels and
tires in the 8. Do-it-yourself section.
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
prevent 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
slippery surfaces.
Using system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady pres-
sure, but do not pump the brakes. The ABS will
operate to prevent the wheels from locking up.
Steer the vehicle to avoid obstacles.
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 malfunction, it switches the ABS off
and illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates normally, but without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked. It is recommended you visit an
INFINITI retailer for this service.
Normal operation
The ABS operates at speeds above 3 to 6 MPH
(5 to 10 km/h). The speed varies according to
road conditions.
When the ABS senses that one 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 pulsa-
tion may indicate that road conditions are haz-
ardous and extra care is required while driving.
Starting and driving5-89
Page 421 of 556
The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and
vehicle motion. Under certain driving condi-
tions, 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 steering
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. When the VDC system operates, the VDC warn-
ing light in the instrument panel flashes so note
the following:
•The road may be slippery or the system may
determine some action is required to help
keep the vehicle on the steered path.
•You may feel a pulsation in the brake pedal
and hear a noise or vibration from under the
hood. This is normal and indicates that the
VDC system is working properly.
•Adjust your speed and driving to the road
conditions.
See Vehicle Dynamic Control (VDC) warning
light in the 2. Instruments and controls sec-
tion.
If a malfunction occurs in the system, the VDC
warning light
illuminates in the instrument
panel. The VDC system automatically turns off.
WARNING
•The VDC system is designed to help the
driver maintain stability but does not pre-
vent accidents due to abrupt steering opera-
tion at high speeds or by careless or danger-
ous driving techniques. Reduce vehicle
speed and be especially careful when driv- ing and cornering on slippery surfaces and
always drive carefully.
•Do not modify the vehicle’s suspension. If
suspension parts such as shock absorbers,
struts, springs, stabilizer bars, bushings
and wheels are not INFINITI recommended
for your vehicle or are extremely deterio-
rated, the VDC system may not operate
properly. This could adversely affect vehicle
handling performance, and the VDC warning
light
may illuminate.
•If brake related parts such as brake pads,
rotors and calipers are not INFINITI recom-
mended or are extremely deteriorated, the
VDC system may not operate properly and
the VDC warning light
may illuminate.
•If engine control related parts are not
INFINITI recommended or are extremely de-
teriorated, the VDC warning light
may
illuminate.
•When driving on extremely inclined sur-
faces such as higher banked corners, the
VDC system may not operate properly and
the VDC warning light
may illuminate.
Do not drive on these types of roads.
