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

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
BREAK-IN SCHEDULE

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.

•When a replacement tire is mounted or a
wheel is replaced, the TPMS will not
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 Con-
tact an INFINITI retailer as soon as pos-
sible for tire replacement and/or system
resetting.
•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 willactivate 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)".
STOPPING VEHICLE
WARNING
•Be sure to apply the parking brake
firmly.
•Be sure that P (Park) is engaged.
•Never change tires when the vehicle is
on a slope, ice or slippery area. This is
hazardous.
•Never change tires when the oncoming
traffic is close to your vehicle. Call for
professional road assistance.
1. Safely move the vehicle off the road away
from traffic.
2. Turn on the hazard indicator flasher lights.
3. Park on a level surface.
4. Apply the parking brake.
5. Press the P (Park) button.
6. Turn off the engine.7. Open the hood and set up the triangle
reflector (if equipped):
•To warn other traffic.
•To signal professional road assistance
personnel that you need assistance.
8. Have all passengers get out of the vehicle
and stand in a safe place, away from
other traffic and clear of the vehicle.
In case of emergency6-3

adversely affect the ride, braking, han-
dling, VDC system, ground clearance,
body-to-tire clearance, tire chain clear-
ance, speedometer calibration, head-
light aim and bumper height. Some of
these effects may lead to accidents and
could result in serious personal injury.
•For 2WD models, if your vehicle was
originally equipped with 4 tires that
were the same size and you are only re-
placing 2 of the 4 tires, install the new
tires on the rear axle. Placing new tires
on the front axle may cause loss of ve-
hicle control in some driving conditions
and cause an accident and personal in-
jury.
•If the wheels are changed for any rea-
son, always replace with wheels which
have the same offset dimension. Wheels
of a different offset could cause prema-
ture tire wear, degrade vehicle handling
characteristics, affect the VDC system
and/or interference with the brake
discs. Such interference can lead to de-
creased braking efficiency and/or early
brake pad wear. For additional informa-
tion on wheel offset dimensions, refer to
"Wheels and Tires".
•When a replacement tire is mounted or a
wheel is replaced, the TPMS will not
function and the low tire pressure warn-
ing light will flash for approximately 1
minute. The light will remain on after 1
minute. Contact an INFINITI retailer as
soon as possible for tire replacement
and/or system resetting.
•Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
•The TPMS sensor may be damaged if it
is not handled correctly. Be careful when
handling the TPMS sensor.
•When replacing the TPMS sensor, the ID
registration may be required. It is rec-
ommended that you visit an INFINITI re-
tailer for ID registration.
•Do not use a valve stem cap that is not
specified by INFINITI. The valve stem
cap may become stuck.
•Be sure that the valve stem caps are cor-
rectly fitted. Otherwise the valve may
be clogged up with dirt and cause a mal-
function or loss of pressure.
•Do not install a damaged or deformed
wheel or tire even if it has been repaired.
Such wheels or tires could have struc-
tural damage and could fail without
warning.
•The use of retread tires is not recom-
mended.
•For additional information regarding
tires, refer to "Important Tire Safety
Information" (US) or "Tire Safety Infor-
mation" (Canada) in the Warranty In-
formation Booklet.
Care of wheels
•Wash the wheels when washing the ve-
hicle to maintain their appearance.
•Clean the inner side of the wheels when
the wheel is changed or the underside of
the vehicle is washed.
•Do not use abrasive cleaners when wash-
ing the wheels.
•Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.
•INFINITI recommends waxing the road
wheels to protect against road salt in ar-
eas where it is used during winter.
