LDP system operation
The LDP system provides a lane departure
warning and brake control assistance when
the vehicle is driven at speeds of approxi-
mately 45 MPH (70 km/h) and above.
When the vehicle approaches either the left
or the right side of the traveling lane, a
warning chime will sound and the lane
departure warning light (orange) on the
instrument panel will blink to alert the
driver. Then, the LDP system will automa-
tically apply the brakes for a short period
of time to help assist the driver to return the vehicle to the center of the traveling
lane.
The warning and assist functions will stop
when the vehicle returns to a position
inside of the lane marker.

The warning and assist functions of the
LDP system are not designed to work under
the following conditions:
.When you operate the lane change
signal and change the traveling lanes
in the direction of the signal. (The LDP
system will be deactivated for approxi-
mately 2 seconds after the lane change
signal is turned off.)
. When the vehicle speed lowers to less
than approximately 45 MPH (70 km/h).
After the above conditions have finished
and the necessary operating conditions are
satisfied, the warning and assist functions
will resume.
Condition B:
The assist function of the LDP system is not
designed to work under the following
conditions (warning is still functional):
. When the brake pedal is depressed.
. When the steering wheel is turned as
far as necessary for the vehicle to
change lanes.
. When the accelerator pedal is de-
pressed while the brake control assist is provided.
. When the Intelligent Cruise Control (ICC)
approach warning occurs.
. When the hazard warning flashers are
operated.
. When driving on a curve at high speed.
After the above conditions have finished
and the necessary operating conditions are
satisfied, the LDP brake control assist
function will resume.
Condition C:
Under the following conditions, a beep will
sound and the LDP system will be canceled
automatically. The LDP ON indicator light
will blink in green, and the LDP system
cannot be activated:

NOTE:
The approach warning chime may sound
and the system display may blink when
the ICC sensor detects some reflectors
*A
which are fitted on vehicles in other lanes
or on the side of the road. This may cause
the ICC system to decelerate or accelerate
the vehicle. The ICC sensor may detect
these reflectors when the vehicle is driven
on winding roads, hilly roads or when
entering or exiting a curve. The ICC sensor
may also detect reflectors on narrow roads
or in road construction zones. In these
cases you will have to manually control
the proper distance ahead of your vehicle.Also, the sensor sensitivity can be affected
by vehicle operation (steering maneuver or
driving position in the lane) or traffic or
vehicle condition (for example, if a vehicle
is being driven with some damage).
Automatic cancellation
A chime sounds under the following con-
ditions and the control is automatically
canceled.
.
When the vehicle ahead is not detected
and your vehicle is traveling below the
speed of 15 MPH (24 km/h)
. When the system judges the vehicle is
at standstill
. When the selector lever is not in the D,
DS or Manual mode
. When the windshield wipers are operat-
ing at low (LO) or high speed (HI). If the
vehicle is equipped with a rain sensing
auto-wiper, the system may cancel
when the wipers are set to intermittent
(INT).
. When the parking brake is applied
. When the SNOW mode switch is turned
ON
. When the VDC system is turned off
. When ABS or VDC (including the trac-
tion control system) operates .
When driving into a strong light (for
example, sunlight)
. When distance measurement becomes
impaired due to adhesion of dirt or
obstruction to the sensor
. When a wheel slips

Operating Distance Control Assist
(DCA) system
To turn on the DCA system, push the
dynamic driver assistance switch on the
steering wheel after starting the engine.
The Distance Control Assist (DCA) system
switch indicator light in the dot matrix
liquid crystal display will illuminate. Push
the dynamic driver assistance switch again
to turn off the DCA system. The Distance
Control Assist (DCA) system switch indica-
tor light will turn off.
The system will start to operate after the
vehicle speed becomes above approxi-mately 3 MPH (5 km/h).
WARNING
When the DCA system is not necessary, be
sure to turn off the DCA switch. Using the
system when it is not necessary may result
in an accident.
The dynamic driver assistance switch is
used for both the LDP and DCA systems.
When the dynamic driver assistance switch
is pushed, the LDP system will also turn on
or off simultaneously. The DCA system can
be individually set to on or off on the
display. If the system is set to off, the
system will not turn on even if the dynamic
driver assistance switch is pushed to on. To
set the system to on or off on the display,
see
“Setting DCA system to ON/OFF” later
in this section.

2. Move the selector lever to the P (Park)position.
3. To help prevent the vehicle from rolling into the street when parked on a
sloping drive way, it is a good practice
to turn the wheels as illustrated.
.HEADED DOWNHILL WITH CURB:*1
Turn the wheels into the curb and
move the vehicle forward until the
curb side wheel gently touches the
curb.
.HEADED UPHILL WITH CURB:*2
Turn the wheels away from the curb
and move the vehicle back until the
curb side wheel gently touches the
curb.
.HEADED UPHILL OR DOWNHILL, NOCURB:
*3
Turn the wheels toward the side of
the road so the vehicle will move
away from the center of the road if it
moves.
4. Push the ignition switch to the OFF position.
WARNING
If the engine is not running or is turned off
while driving, the power assist for the
steering will not work. Steering will be
harder to operate.
The power assisted steering uses a hy-
draulic pump, driven by the engine, to
assist steering.
If the engine stops or the drive belt breaks,
you will still have control of the vehicle.
However, much greater steering effort is
needed, especially in sharp turns and at
low speeds.
BRAKING PRECAUTIONS
The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
You may feel a small click and hear a sound
when the brake pedal is fully depressed
slowly. This is not a malfunction and
indicates that the brake assist mechanism
is operating properly.
Vacuum assisted brakes
The brake booster aids braking by using
engine vacuum. If the engine stops, you
can stop the vehicle by depressing the
brake pedal. However, greater foot pres-
sure on the brake pedal will be required to
stop the vehicle and the stopping distance
will be longer.
When the brake pedal is depressed slowly
and firmly, you may hear a clicking noise
and feel a slight pulsation. This is normal
and indicates that the Brake Assist System
is operating.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet.
As a result, your braking distance will be
longer and the vehicle may pull to one side

POWER STEERING BRAKE SYSTEM

ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
.The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless or
dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remember
that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if you
are using tire chains. Always maintain a
safe distance from the vehicle in front of
you. Ultimately, the driver is responsible
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. See “Tireand Loading Information label”
in the
“9. Technical and consumer informa-
tion” section of this manual.
—For detailed information, see
“Wheels and tires” in the“8. Main-
tenance and do-it-yourself” section
of this manual.
The Anti-lock Braking System (ABS) con-
trols 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 pre-
venting 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
ABS will operate to prevent 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 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.

5-86Starting and driving
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h). The speed varies
according to road conditions.
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.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 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 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” in the“2. Instruments and
controls” section.
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
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,
and the VDC warning light
will not
