[ Edit: 2012/ 1/ 17 Model: V36-D ]and avoid driving when tired. Never drive
when under the influence of alcohol or
drugs (including prescription or over-the-
counter drugs which may cause drowsi-
ness). Always wear your seat belt as
outlined in the “ Seat belts ” (P.1-14) of this
manual, and also instruct your passengers
to do so.
Seat belts help reduce the risk of injury in
collisions and rollovers. In a rollover crash,
an unbelted or improperly belted person is
significantly more likely to be injured or
killed than a person properly wearing a
seat belt.
OFF-ROAD RECOVERY GUID-55350CDC-B327-47DB-A929-95DDE2B6F88F
If the right side or left side wheels may
unintentionally leave the road surface.
Maintain control of the vehicle by following
the procedure below. Please note that this
procedure is only a general guide. The
vehicle must be driven as appropriate
based on the conditions of the vehicle,
road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering
wheel with both hands and try to hold a
straight course. 4. When appropriate, slowly release the
accelerator pedal to gradually slow the
vehicle.
5. If there is nothing in the way, steer the
vehicle to follow the road while the
vehicle speed is reduced. Do not
attempt to drive the vehicle back onto
the road surface until vehicle speed is
reduced.
6. When it is safe to do so, gradually turn
the steering wheel until both tires
return to the road surface. When all
tires are on the road surface, steer the
vehicle to stay in the appropriate
driving lane. .
If you decide that it is not safe to
return the vehicle to the road surface
based on vehicle, road or traffic
conditions, gradually slow the vehi-
cle to a stop in a safe place off the
road. RAPID AIR PRESSURE LOSS GUID-F6877DBB-5B63-45D0-9CA2-EC1F801DC510
Rapid air pressure loss or a “ blow-out ” can
occur if the tire is punctured or is damaged
due to hitting a curb or pothole. Rapid air
pressure loss can also be caused by
driving on under-inflated tires.
Rapid air pressure loss can affect the
handling and stability of the vehicle,
especially at highway speeds.
Help prevent rapid air pressure loss by
maintaining the correct air pressure and
visually inspect the tires for wear and
damage. See “ Wheels and tires ” (P.8-33) of
this manual.
If a tire rapidly loses air pressure or
“ blows-out ” while driving maintain control
of the vehicle by following the procedure
below. Please note that this procedure is
only a general guide. The vehicle must be
driven as appropriate based on the condi-
tions of the vehicle, road and traffic.
WARNING The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air pressure.
Losing control of the vehicle may cause a

rain, fog, or other bad weather. Decele-
rate the vehicle speed by depressing the
brake pedal, depending on the distance
to the vehicle ahead and the surround-
ing circumstances in order to maintain a
safe distance between vehicles.
. Although the brake operation is con-
trolled by the system, the system does
not automatically stop the vehicle. If the
vehicle speed falls below approximately
20 MPH (32 km/h), the Intelligent Cruise
Control system is automatically canceled
and a warning chime sounds. (The brake
control is also canceled.) . The system may not detect the vehicle in
front of you in certain road or weather
conditions. To avoid accidents, never use
the Intelligent Cruise Control system
under the following conditions:
— On roads where the traffic is heavy
or there are sharp curves
— On slippery road surfaces such as
on ice or snow, etc.
— During bad weather (rain, fog, snow,
etc.)

PREVIEW FUNCTION (for Intelligent
Cruise Control system equipped
models) GUID-96A87E96-2026-4122-93F8-399D8C784D61
The ICC system with the preview function
identifies the need to apply emergency
braking by sensing the vehicle ahead in
the same lane and the distance to the
vehicle ahead and relative speed from it, it
applies the brake pre-pressure before the
driver depresses the brake pedal and helps
improve brake response by reducing pedal
free play.

blinking.
When an object is detected, the indicator
(green) appears and blinks (the tone
sounds intermittently). When the vehicle
moves closer to the object, the color of the
indicator turns yellow and the rate of
blinking increases (the rate of the tone
increases). When the corner of the vehicle
is very close to the object, less than 11.8 in
(30 cm) away, the indicator stops blinking
and turns red (the tone sounds continu-
ously).
When the rear view monitor is displayed,
the colors of the sonar indicator and the
distance guide lines in the rear view
indicate different distances to the object.
The sonar indicator can be turned off in the
SONAR setting display. (See “ How to use
SETTING button ” (P.4-14) for the “ Sonar ”
settings.) When the sonar indicator is off,
only a tone sounds when the sonar detects
obstacles. SSD0929
SONAR SYSTEM OFF SWITCH GUID-446340A3-E5C0-4566-9701-88DF98FE3774
The sonar system OFF switch on the
instrument panel allows the driver to turn
the sonar system on and off. To turn the
sonar system on and off, the ignition
switch must be in the “ ON ” position. The
indicator light
* 1
on the switch will
illuminate when the system is turned off.
If the indicator light flashes when the
sonar system is not turned off, it may
indicate a malfunction in the sonar system. GUID-7A26DC9E-F480-487F-A4C2-174FF498CC5C
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.POWER STEERING

When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional brake booster even
with light pedal force.

When the Preview Function identifies the
need to apply emergency braking by
sensing a vehicle ahead in the same lane
and the distance and relative speed from
it, it applies the brake pre-pressure before
the driver depresses the brake pedal and
helps improve brake response by reducing
pedal free play. . This system will not operate when the
vehicle is moving at approximately 20
MPH (32 km/h) or less.
. The pre-pressure function ceases when
the following conditions are met:
1) When the driver depresses the
accelerator pedal or the brake
pedal.
2) If the driver does not operate the
accelerator or brake pedal within
approximately 1 second. SSD0338

The sensor for the Preview Function is
common with Intelligent Cruise Control and
is located below the front bumper.
To keep the Preview Function operating
properly, be sure to observe the following:
. Always keep the sensor clean. Wipe
with a soft cloth carefully so as not to
damage the sensor.
. Do not strike or damage the areas
around the sensor. Do not touch or
remove the screw located on the
sensor. Doing so could cause failure
or malfunction. If the sensor is da-
maged due to an accident, contact an
INFINITI retailer.
. Do not attach a sticker (including
transparent material) or install an
accessory near the sensor. This could
cause failure or malfunction. ANTI-LOCK BRAKING SYSTEM (ABS) GUID-FD13D872-FF09-485D-9889-39301203B8FE
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 “ Tire and loading information label ” (P.9-
14) of this manual.
— For detailed information, see
“ Wheels and tires ” (P.8-33) 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 GUID-CD765EBE-4FB0-423D-988E-36D396A7E6A5
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.

[ Edit: 2012/ 1/ 17 Model: V36-D ]WARNINGDo not pump the brake pedal. Doing so may
result in increased stopping distances.
Self-test feature GUID-EC96AE96-D9F6-4F19-A5A9-937C4D6337A4
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. Normal operation GUID-36C3BA08-72B5-4E9B-96CF-93CCD7FE6655
The 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. GUID-B2222C83-77D9-46CF-971F-591ADE2397C3
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.
