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.2-15).
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system automa-
tically 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.2-15) and “Vehicle Dynamic Control (VDC) off indicator light” (P.2-17).
The computer has a built-in diagnostic
feature that tests the system each time you
start the INFINITI Direct Response Hybrid
®
System 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 mal-
function.
RISE-UP AND BUILD-UP
The system gradually adjusts braking power
during normal braking to help provide an
enhanced brake feel.
BRAKE FORCE DISTRIBUTION
During 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 rise-up and build-up, and brake
force distribution system may not be
effective depending on the driving
condition. Always drive carefully and
attentively.
. Do not modify the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs, sta-
bilizer bars, bushings and wheels are
not INFINITI recommended for your
vehicle or are extremely deteriorated,
the VDC system may not operate
properly. This could adversely affect
vehicle handling performance, and
the VDC warning light
may
illuminate.
. If brake related parts such as brake
pads, rotors and calipers are not
INFINITI recommended or are extre-
mely deteriorated, the VDC system
may not operate properly and the
VDC warning light
may illumi-
nate.
. If engine control related parts are not
INFINITI recommended or are extre-
mely deteriorated, the VDC warning
light
may illuminate.
. When driving on extremely inclined
surfaces such as higher banked cor-
Starting and driving5-131

Before attempting to jump start the vehicle,
make sure the fuel tank is not empty and the
correct starting procedure is followed. See
“Starting the INFINITI Direct Response
Hybrid
®System” (P.5-14). Do not drive the
vehicle on battery power only if the fuel tank
is empty. The Lithium ion (Li-ion) battery will
become discharged and the INFINITI Direct
Response Hybrid
®System will turn off.
CONFIRM BATTERY IS DIS-
CHARGED
If any of the following conditions occurs, the
12-volt battery might discharged:
. The instrument cluster and/or headlights
are not normal brightness.
. Audio accessories cannot be turned on.
. The hybrid system does not become
READY to drive mode.
. The ignition switch cannot be placed in
the ON position.
Check the following if you notice above
conditions.
1. Check that the 12-volt battery terminals are tight and clean. See “12-volt battery”
(P.8-14). The 12-volt battery is located
on the left hand side of the trunk behind
an access panel. If the 12-volt battery
terminals are loose, it is recommended
you contact an INFINITI retailer. 2. If the 12-volt battery terminals are tight
and clean, try to jump start the vehicle.
See “Jump starting” (P.6-5).
If the hybrid system still does not start, it is
recommended that you contact an INFINITI
retailer. To start your INFINITI Direct Response
Hybrid
®System with a booster battery, the
instructions and precautions below must be
followed.
Jump starting provides power to the 12 volt
system to allow the electrical systems to
operate. The electrical systems must be
operating to allow the Lithium ion (Li-ion)
battery to be charged. Jump starting does
not charge the Li-ion battery.
WARNING
. If done incorrectly, jump starting can
lead to a 12-volt battery explosion,
resulting in severe injury or death. It
could also damage your vehicle.
. Explosive hydrogen gas is always
present in the vicinity of the 12-volt
battery. Make sure that the vent
tube is mounted.
. Do not allow battery fluid to come
into contact with eyes, skin, clothing
or painted surfaces. Battery fluid is a
corrosive sulfuric acid solution which
can cause severe burns. If the fluid
should come into contact with any-
thing, immediately flush the con-
tacted area with water.
. Keep the 12-volt battery out of the
reach of children.
