WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.
Self-test featureY51D-V-E01-9FAB00BB-F2BE-4168-BD75-236754B398C1The ABS includes electronic sensors, elec-
tric 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 pulsa-
tion 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 operates normally,
but without anti-lock assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the
vehicle checked by an INFINITI retailer.
Normal operationY51D-V-E01-97EC20E5-32E3-4D14-80B0-197E7EAA54F0The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h).
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. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care is
required while driving.
Y51D-V-E01-4A9596A2-6386-4C22-A04D-18A64B158580The 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 func-
tion).
. 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 condi-
tions).
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
warning light
in the instrument panel
VEHICLE DYNAMIC CONTROL (VDC) SYSTEM

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) warn-
ing light” (P.2-16).
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system auto-
matically turns off.
The VDC OFF switch is used to turn off the
VDC system. The VDC off indicator light
illuminates to indicate the VDC system is
off. When the VDC switch 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 VDC warning light
flashes if
this occurs. All other VDC functions are off,
except for rise-up and build-up and brake
force distribution, and the VDC warning light
will not flash. The VDC system is
automatically reset to on when the ignition
switch is placed in the off position then
back to the on position.
See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-16) and “Vehicle Dynamic
Control (VDC) off indicator light” (P.2-19).
The computer has a built-in diagnostic
feature that tests the system each time you
start the engine and move the vehicle
forward or in reverse at a slow speed.
When the self-test occurs, you may hear a
“clunk” noise and/or feel a pulsation in the
brake pedal. This is normal and is not an
indication of a malfunction.
ACTIVE TRACE CONTROL (if so
equipped)
Y51D-V-E01-B5B4CBB7-02DE-42E3-B478-AAEA8DEBF723This system senses driving based on the
driver’s steering and acceleration/braking
patterns, and controls brake pressure at
individual wheels and engine output to
help smooth vehicle response.
When the drive mode selector switch is set
to the “SPORT” mode, the amount of brake
control provided by active trace control is
reduced.
When the VDC OFF switch is used to turn off
the VDC system, the active trace control system is also turned off.
If the active trace control is not functioning
properly, the IBA OFF indicator light illumi-
nates in the instrument panel.
RISE-UP AND BUILD-UPY51D-V-E01-87710884-81A9-4A5A-9076-A774904FE42DThe system gradually adjusts braking
power during normal braking to help
provide an enhanced brake feel.
BRAKE FORCE DISTRIBUTIONY51D-V-E01-5B46CABC-FBC6-4BB8-9C50-B12A7A558D2EDuring braking while driving through turns,
the system optimizes the distribution of
force to each of the four wheels depending
on the radius of the turn.
WARNING
.
The VDC system is designed to help the
driver maintain stability but does not
prevent accidents due to abrupt steering
operation at high speeds or by careless
or dangerous driving techniques. Reduce
vehicle speed and be especially careful
when driving and cornering on slippery
surfaces and always drive carefully.
. The active trace control (if so equipped),
rise-up and build-up and brake force
distribution systems may not be effec-

securely. Check the belt webbing for cuts,
fraying, wear or damage.
Seats:Check seat position controls such as
seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraints move up
and down smoothly and that the locks (if
so equipped) hold securely in all latched
positions.
Steering wheel: Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly
and that the wipers do not streak.
Under the hood and vehicleY51D-V-E01-B3361551-A047-4A72-ACCF-65F901F88160The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel). Battery*:
Check the fluid level in each cell.
It should be between the MAX and MIN
lines. Vehicles operated in high tempera-
tures or under severe condition require
frequent checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake fluid level*: Make sure that the
brake fluid level is between the MAX and
MIN lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no belt
is frayed, worn, cracked or oily.
Engine oil level*: Check the level after parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
Exhaust system:
Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in-
spected by an INFINITI retailer. (See
“Precautions when starting and driving”
(P.5-3) for exhaust gas (Carbon monoxide).)
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks or
if gasoline fumes are evident, check for the
cause and have it corrected immediately.
Power steering fluid level* and lines:
Check the level when the fluid is cold,
with the engine off. Check the lines for
proper attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
