10. Drive forward and back up as prompted by
the parking sensor system warning dis-
plays, several times if necessary.
Once you have exited the parking space com-
pletely, the steering wheel is moved to the
straight-ahead position. You hear a tone and
the [Park Assist switched off] message appears
in the display. You will then have to steer and
merge into traffic on your own. The parking
sensor system is still available. You can take
over the steering before the vehicle has exited
the parking space completely. This is useful, for
example when you recognise that it is already
possible to pull out of the parking space.
CANCELING IPA
Stop the movement of the steering wheel or
steer yourself. IPA will be immediately can-
celed. The [Park Assist canceled] message ap-
pears in the vehicle information display.
or
Press the parking sensor system OFF switch.
The parking sensor system is switched off and
IPA is immediately canceled The [Park Assist
canceled] message appears in the vehicle infor-
mation display.IPA is canceled automatically if:
•The electric parking brake is applied
•Parking using IPA is no longer possible
•You are driving faster than 5 MPH (10 km/h)
•A wheel spins and VDC intervenes or fails.
Thewarning light lights up in the
combination meter.
A warning tone sounds. The parking symbol
disappears and the vehicle information display
shows the [Park Assist canceled] message.
When IPA is canceled, you must steer again
yourself.
WARNING
•The parking sensor system is a convenience
but it is not a substitute for proper parking.
Always look around and check that it is safe
to do so before parking. Always move
slowly.
•Read and understand the limitations of the
parking sensor system as contained in this
section. Inclement weather may affect the
function of the parking sensor system; this
may include reduced performance or a false
activation.
•This system is not designed to prevent con-
tact with small or moving objects.
•The system is designed as an aid to the
driver in detecting large stationary objects
to help avoid damaging the vehicle. The
system will not detect small objects below
the bumper, and may not detect objects that
are too close to the bumper or on the
ground.
•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
•Keep the interior of the vehicle as quiet as
possible to hear the tone clearly.
•Keep the sensors (located on the bumper
fascia) free from snow, ice and large accu-
mulations of dirt. Do not clean the sensors
with sharp objects. If the sensors are cov-
ered, the accuracy of the sensor function
will be diminished.
WARNING
INFINITI recommends only to use frameless
type license plate holders.
The parking sensor system may not function
correctly if the license plate is placed in a
frame as illustrated.

PARKING SENSOR OVERVIEW
1Possible parking sensor locations
The parking sensor system is an electronic
parking aid with ultrasonic sensors. The park-
ing sensor system indicates audibly the dis-
tance between your vehicle and an object. It
monitors the area around your vehicle using
sensors in the front and rear bumper. Possible
sensor configurations include a 4 sensor, 10
sensor or 12 sensor configuration.

Starting and driving5-75

For the vehicle equipped with rear sensors (Type
A):
The system informs you about rear obstacles
with visual and audible signals when the shift
lever is in the R (Reverse) position.
The intermittent tone will stop after 3 seconds
when an obstacle is detected by only the corner
sensor and the distance does not change. The
tone will stop when the obstacle moves away
from the vehicle.
For the vehicle equipped with front and rear sen-
sors (Type B and C):
The system informs you about front obstacles
with visual and audible signals when the shift
lever is in the D (Drive) position and both front
and rear obstacles when the shift lever is in the
R (Reverse) position.
The intermittent tone will stop after 3 seconds
when an obstacle is detected by only the corner
sensor and the distance does not change. The
tone will stop when the obstacle moves away
from the vehicle.

When the corner of the vehicle moves closer to
an object, the corner sensor indicators
1appear (if equipped).
When the center of the vehicle moves close to
an object, the center indicator
2appears.
When the object is detected, the indicator
(green) appears and blinks and the tone sounds
intermittently. When the vehicle moves closer to
the object, the color of the indicator turns
yellow and the rate of the blinking increases.
When the vehicle is very close to the object, the
indicator stops blinking and turns red, and the
tone sounds continuously.

•Clean the sensors.•Switch the ignition back on.
The problem may be caused by an external source of radio or ultrasound
waves.
See if the Parking Sensor System functions in a different location.
During the first 1,200 miles (2,000 km), follow
these recommendations to obtain maximum
engine performance and ensure the future reli-
ability and economy of your new vehicle. Failure
to follow these recommendations may result in
shortened engine life and reduced engine per-
formance.
•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.
You should also observe these notes on
break-in if the engine or parts of the drive train
on your vehicle have been replaced.

CAUTION
In certain driving and driving safety systems,
the sensors adjust automatically while a cer-
tain distance is being driven after the vehicle
has been delivered or after repairs. Full system
effectiveness is not reached until the end of
this teach-in process.
Brake pads/linings and rotors that are either
new or have been replaced only achieve opti-
mum braking effect after several hundred
miles of driving. Compensate for the reduced
braking effect by applying greater force to the
brake pedalFollow 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
minimize 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 Distances
•Observing the speed limit and not ex-
ceeding 60 MPH (97 km/h) (where legally
allowed) can improve fuel efficiency due
to reduced aerodynamic drag.
•Maintaining a safe following distance
behind other vehicles reduces unneces-
sary braking.
•Safely monitoring traffic to anticipate
changes in speed permits reduced brak-
ing and smooth acceleration changes.
•Select a gear range suitable to road
conditions.
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.
Utilize a map or navigation system to determine
the best route to save time.
FUEL EFFICIENT DRIVING TIPS

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
Wheels and Tiresin the9. Maintenance and
Schedulessection.)
–For detailed information, seeWheels and
tiresin the8. Do-it-yourselfsection.
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.
