ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
• The ABS is a sophisticated device, but it
cannot prevent accidents resulting from
careless or dangerous driving tech-
niques. It can help maintain vehicle con-
trol during braking on slippery surfaces.
Remember that stopping distances on
slippery surfaces will be longer than on
normal surfaces even with ABS. Stop-
ping distances may also be longer on
rough, gravel or snow covered roads, or
if you are using tire chains. Always main-
tain a safe distance from the vehicle in
front of you. Ultimately, the driver is re-
sponsible 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 spare tire, make
sure that it is the proper size and type
as specified on the Tire and Loading
Information label. For additional in-
formation, see “Tire and Loading In-
formation label” (P. 8-30).
– For additional information, see
“Wheels and tires” (P. 8-28).
The 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 the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate to pre-
vent 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 Anti-lock Braking System (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 op-
erates 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 that you visit an
INFINITI retailer for this service.
5-166Starting and driving

•Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not INFINITI
approved for your vehicle or are ex-
tremely deteriorated, the ABLS system
may not operate properly. This could ad-
versely affect vehicle handling perfor-
mance, and the slip indicator light may
illuminate.
• If brake related parts such as brake pads,
rotors and calipers are not INFINITI rec-
ommended or are extremely deterio-
rated, the ABLS system may not operate
properly and the slip indicator light may
illuminate.
• If wheels or tires other than the INFINITI
recommended ones are used, the ABLS
system may not operate properly and
the slip indicator light may illuminate. The VDC system uses various sensors to
monitor driver inputs and vehicle motion. Un-
der certain driving conditions, the VDC sys-
tem 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 fol-
lowing conditions:– Understeer (vehicle tends to not follow the steered path despite increased steer-
ing 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 prevent
loss of vehicle control in all driving situations.
When the VDC system operates, theindicator light in the instrument panel flashes
to 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.
For additional information, see “Slip indicator
light” (P. 2-20) and ”Vehicle Dynamic Control
(VDC) OFF indicator light” (P. 2-20).
If a malfunction occurs in the system, the
andindicator lights come on in the
instrument panel. The VDC system automati-
cally turns off when these indicator lights are
on.
The vehicle information display is used to turn
off the VDC system. The
indicator light
and the FEB with Pedestrian Detection sys-
tem warning light illuminate to indicate the
VDC system is off.
When the vehicle information display is used
to turn off the system, the VDC system still
operates to prevent one drive wheel from
slipping by transferring power to a non-
slipping drive wheel. The
indicator light
flashes if this occurs. All other VDC functions
are off and the
indicator light will not
flash.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-168Starting and driving

When the vehicle is stopped on a hill, the hill
start assist system automatically keeps the
brakes applied to help prevent the vehicle
from rolling backward in the time it takes the
driver to release the brake pedal and apply
the accelerator.
The hill start assist system will operate auto-
matically under the following conditions:
• The transmission is shifted to a forward orreverse gear.
• The vehicle is stopped completely on a hill by applying the brake. The maximum hold-
ing time is 2 seconds. After 2 seconds the
vehicle will begin to roll back and the hill
start assist system will stop operating
completely.
The hill start assist system will not operate
when the shift position is placed in the N
(Neutral) or P (Park) position or on a flat and
level road. The sonar system sounds a tone to inform the
driver of obstacles around the vehicle using
the sonar sensors located in the front and
rear bumpers..
When the sonar system is turned on, the
sonar view will automatically appear in the
vehicle information display.
WARNING
• The sonar system is a convenience but it
is not a substitute for proper parking. •
The driver is always responsible for
safety during parking and other maneu-
vers. Always look around and check that
it is safe to do so before parking.
• Read and understand the limitations of
the sonar system as contained in this
section. The colors of the corner sonar
indicator indicates different distances to
the object.
• Inclement weather or ultrasonic sources
such as an automatic car wash, a truck's
compressed-air brakes or a pneumatic
drill may affect the function of the sys-
tem; this may include reduced perfor-
mance or a false activation.
• The sonar system is designed as an aid to
the driver in detecting large stationary
objects to help avoid damaging the
vehicle.
• The sonar system is not designed to pre-
vent contact with small or moving ob-
jects. Always move slowly. The system
will not detect small objects below the
bumper, and may not detect objects
close to the bumper or on the ground.
• The sonar system may not detect the fol-
lowing objects: fluffy objects such as
snow, cloth, cotton, glass, wool, etc.;
thin objects such as rope, wire and chain,
etc.; or wedge-shaped objects.

FRONT AND REAR SONAR SYSTEM
(if so equipped)
5-172Starting and driving

If your vehicle sustains damage to the bum-
per fascia, leaving it misaligned or bent, the
sensing zone may be altered causing inaccu-
rate measurement of obstacles or false
alarms.
CAUTION
• Excessive noise (such as audio system
volume or an open vehicle window) will
interfere with the tone and it may not be
heard.
• Keep the sonar sensors (located on the
bumper fascias) free from snow, ice and
large accumulations of dirt. Do not clean
the sensors with sharp objects. If the
sensors are covered, the accuracy of the
sonar function will be diminished.
SYSTEM OPERATION
1Center sonar sensors
2Corner sonar sensors
The system informs with a visual and audible
alert of:
• front obstacles when the shift lever is in the D (Drive) position
• front and rear obstacles when the shift le- ver is in the R (Reverse) position How the system alerts of obstacles:
The system is deactivated at speeds above 6
mph (10 km/h). It is reactivated at lower
speeds.
The intermittent tone will stop after several
seconds when the obstacle is identified only
with the center sensor. The tone will stop
when the obstacle gets away from the
vehicle.
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 blink-
ing and turns red, and the tone sounds
continuously.

SYSTEM TEMPORARILY
UNAVAILABLE
When sonar blockage is detected, the system
will be deactivated automatically.
The system is not available until the condi-
tions no longer exist.
The sonar sensors may be blocked by tempo-
rary ambient conditions such as splashing
water, mist or fog. The blocked condition
may also be caused by objects such as ice,
frost or dirt obstructing the sonar sensors.
Action to take:
When the above conditions no longer exist,
the system will resume automatically.
SYSTEM MAINTENANCE

• If the sonar sensors are dirty, wipe them offwith a soft cloth while being careful to not
damage them.
• The sonar sensors may be blocked by tem- porary ambient conditions such as splash-
ing water, mist or fog. The blocked condi-
tion may also be caused by objects such as
ice, frost or dirt obstructing the sonar sen-
sors. Check for and remove objects ob-
structing the area around the sonar
sensors.
• Do not subject the area around the sonar sensors to strong impact. Also, do not re-
move or disassemble the sonar sensors. If
the sonar sensors and peripheral areas are
deformed in an accident, etc., have the so-
nar sensors checked by an INFINITI retailer.
• Do not attach stickers (including transpar- ent material), install accessories or apply
additional paint on the sonar sensors and
their surrounding areas. This may cause a
malfunction or improper operation.
• When washing the vehicle using a high- pressure washer, do not apply direct
washer pressure on the sonar sensors. This
may cause a malfunction of the sonar
sensors. The Idling Stop System activates to prevent
unnecessary fuel consumption, exhaust
emissions and noise.
• When you stop the vehicle, the engine is
turned off automatically.
• When you release the brake pedal to begin moving again, the engine is turned on
automatically.
WARNING
The engine restarts if the vehicle moves at
approximately 1 mph (2 km/h) or more (on
a downhill grade, etc.) while the engine is
turned off by the Idling Stop System. De-
press the brake pedal immediately to stop
the vehicle to prevent an accident.
CAUTION
At the end of the journey the engine must
be stopped and ignition switch be pushed
off. Lock the vehicle as normal. Pushing the
ignition switch off will shut down all elec-
trical systems. Failure to do this may result
in a discharged battery.
