•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 dis-
play shows the [Park Assist canceled] mes-
sage.
When IPA is canceled, you must steer again
yourself.
WARNING
•The sonar function 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 sonar function as contained in this
section. Inclement weather may affect
the function of the sonar function; this
may include reduced performance or a
false activation.
•The driver is always responsible for
safety during parking and other maneu-
vers.
•The system is designed as an aid to the
driver in detecting large stationary ob-
jects 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.
•Always look around and check that it is
safe to move before parking.

SONAR FUNCTION OVERVIEW
1Possible sonar sensor locationsThe sonar function is an electronic parking
aid with ultrasonic sensors. The sonar func-
tion indicates audibly the distance between
your vehicle and an object. It monitors the
area around your vehicle using sensors in the
front and rear bumper. Possible sensor con-
figurations include a 4 sensor, 10 sensor or
12 sensor configuration.

Type A: 4 sensor system
5-78Starting and driving

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 sec-
onds 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
sensors (Type B and C):
The system informs you about front ob-
stacles 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 sec-
onds 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.

The sonar function is deactivated for the rear
area when you establish an electrical connec-
tion between your vehicle and a trailer.
RANGE OF THE SENSORS
The sonar function does not take into ac-
count obstacles located:
•Below the detection range, e.g. persons,
animals or objects.
•Above the detection range, e.g. overhang-
ing loads, tail sections or loading ramps of
goods vehicles.
SONAR FUNCTION OFF SWITCH
The sonar function OFF switch2on the
lower side of the instrument panel allows the
driver to turn the sonar function on and off.
To turn the sonar function system on and off,
the ignition switch must be in the ON posi-
tion. The indicator light
1on the switch will
illuminate when the system is turned off.
The sonar function will turn on automatically
when the ignition switch is turned from the
OFF position to the ON position.

•The system may not detect the follow-
ing objects: – Fluffy objects such as snow, cloth,
cotton, grass or wool.
– Thin objects such as rope, wire or
chain.
– Wedge-shaped objects.
•If your vehicle sustains damage to the
bumper fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of ob-
jects or false alarms.
CAUTION
Excessive noise (such as audio system vol-
ume or an open vehicle window) will inter-
fere with the tone and it may not be heard.
PROBLEMS WITH SONAR FUNCTION
Problem Possible causes/consequences and solutions
Only the red segments in the sonar function displays
are lit. You also hear a warning tone for approximately
two seconds.
The sonar function is then deactivated and the
indicator light on the sonar function OFF switch lights
up. The sonar function has malfunctioned and has been deactivated.
If problems persist, have the sonar function checked. It is recommended you visit an INFINITI retailer for
this service.
Only the red segments in the sonar function displays
are lit. The sonar function is then deactivated. The sonar sensors are dirty or there is interference.
•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 sonar system functions in a different location.

SYSTEM MAINTENANCE
CAUTION
Keep the surface of the sonar sensors (if
equipped) (located on the front and rear
bumper fascia) free from accumulations of
snow, ice and dirt. Do not scratch the sur-
face of the sonar sensors when cleaning. If
the sensors are covered, the accuracy of
the sonar function will be diminished.During the first 1,200 miles (2,000 km), fol-
low these recommendations to obtain maxi-
mum engine performance and ensure the fu-
ture reliability and economy of your new
vehicle. Failure to follow these recommenda-
tions 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.
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 sys-
tems, the sensors adjust automatically
while a certain distance is being driven af-
ter the vehicle has been delivered or after
repairs. Full system effectiveness is not
reached until the end of this teach-in pro-
cess.
Brake pads/linings and rotors that are ei-
ther new or have been replaced only
achieve optimum braking effect after sev-
eral hundred miles of driving. Compensate
for the reduced braking effect by applying
greater force to the brake pedal

Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer.
The computer has a built-in diagnostic fea-
ture 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 mal-
function. 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 nor-
mally, 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 ac-
cording to road conditions.
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. 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 prop-
erly. However, the pulsation may indicate
that road conditions are hazardous and extra
care is required while driving.The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle 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 conditions: – 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 main-
tain control of the vehicle, but it cannot pre-
vent loss of vehicle control in all driving situ-
ations.

function and the low tire pressure warn-
ing light will flash for approximately 1
minute. The light will remain on after 1
minute. It is recommended you Contact
an INFINITI retailer as soon as possible
for tire replacement and/or system re-
setting.
•Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
•If you used Emergency Tire Sealant to
repair a minor tire puncture, the TPMS
sensor should be checked when repair-
ing or replacing the tire. It is recom-
mended you visit an INFINITI retailer for
this service.
The Tire Pressure Monitoring System (TPMS)
monitors tire pressure of all tires. When the
low tire pressure warning light is lit, and a tire
pressure-related warning (if equipped) ap-
pears in the vehicle information display, one
or more of your tires is significantly under-
inflated. If the vehicle is being driven with low
tire pressure, the TPMS will activate and
warn you of it by the low tire pressure warn-
ing light (in the meter panel). This system will
activate only when the vehicle is driven at
speeds above 16 MPH (25 km/h). For more details about the TPMS, see "Tire
Pressure Monitoring System (TPMS)" in the
"5. Starting and driving" section.
