PREVIEW FUNCTION (for Intelligent
Cruise Control system equipped
models)
GUID-32536B6C-4378-49EB-9FE2-8A7EE457E3F0The 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.
For more details, see“Brake assist”(P.5-
51).
GUID-80396E4C-7829-4CC4-B140-AD5C5CA0C471
CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to obtain
maximum engine performance and ensure
the future reliability and economy of your
new vehicle.
Failure to follow these recommendations
may result in shortened engine life and
reduced engine performance.
. Avoid driving for long periods at con-
stant speed, either fast or slow. Do not
run the engine over 4,000 rpm.
. Do not accelerate at full throttle in any
gear.
. Avoid quick starts.
. Avoid hard braking as much as possi-
ble.
GUID-A0B243EA-7BDA-4E12-AEC1-2F8D7AC85AA5. Accelerate slowly and smoothly. Main-
tain cruising speeds with a constant
accelerator position.
. Drive at moderate speeds on the high-
way.
. Avoid unnecessary stopping and brak-
ing. Keep a safe distance behind other
vehicles.
. Select a gear range suitable to road
conditions.
. Avoid unnecessary prolonged engine
idling.
. Keep your engine tuned up.
. Follow the recommended periodic main-
tenance schedule.
. Keep the tires inflated at the correct
pressure. Improper tire pressure will
increase wear and waste fuel.
. Make sure the front wheels are properly
aligned. Improper alignment will cause
premature tire wear and lower fuel
economy.
. Climate control operation lowers fuel
economy. Use the air conditioner only
when necessary.
. When cruising at highway speeds, it is
more economical to use the air condi-
tioner and leave the windows closed to
reduce drag.

WARNING
.Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite and
cause a fire.
. Never leave the engine running while the
vehicle is unattended.
. Do not leave children unattended inside
the vehicle. They could unknowingly
activate switches or controls. Unat-
tended children could become involved
in serious accidents. .
Safe parking procedures require that
both the parking brake be applied and
the transmission placed into P (Park) for
Automatic Transmission (AT) model or in
an appropriate gear for Manual Trans-
mission (MT) model. Failure to do so
could cause the vehicle to move un-
expectedly or roll away and result in an
accident.
. Make sure the automatic transmission
selector lever has been pushed as far
forward as it can go and cannot be
moved without depressing the foot brake pedal.
1. Firmly apply the parking brake.
2.
Automatic transmission models:
Move the selector lever to the P (Park)
position.
Manual transmission models:
Place the shift lever in the R (Reverse)
gear. When parking on an uphill grade,
place the shift lever in the 1st gear.
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.

WARNING
. The sonar system is a convenience but it
is not a substitute for proper parking.
Always look around and check that it is
safe to do so before parking. Always
move slowly.
. Read and understand the limitations of
the sonar system as contained in this
section. Inclement weather may affect
the function of the sonar system; this
may include reduced performance or a
false activation. .
This system is not designed to prevent
contact with small or moving objects.
. The system is designed as an aid to the
driver in detecting large stationary
objects to help avoid damaging the
vehicle. The system will not detect small
objects below the bumper, and may not
detect objects close to the bumper or on
the ground.
. If your vehicle sustains damage to the
bumper fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of ob-

stacles or false alarms.
CAUTION
Keep the interior of the vehicle as quiet as
possible to hear the tone clearly.
The sonar system sounds a tone to warn
the driver of obstacles near the bumper.
When the“Sonar Display” key is ON, the
sonar indicator will also appear in the
center display. (See “Sonar indicator”(P.5-
48).) The system detects rear obstacles
when the selector or shift lever is in the R
(Reverse) position.
The system may not detect objects at
speeds above 6 MPH (10 km/h) and may
not detect certain angular or moving
objects.
The sonar system detects obstacles up to
3.9 ft (1.2 m) from the bumper with a
decreased coverage area at the outer
corners of the bumper. Refer to the
illustration for approximate zone coverage
areas. As you move closer to the obstacle,
the rate of the tone increases. When the
obstacle is less than 11.8 in (30 cm) away, the tone will sound continuously.
Keep the corner/center sonar (located on
the bumper fascia) free from snow, ice and
large accumulations of dirt (do not clean
the sonar with sharp objects). If the sonar
is covered, it will affect the accuracy of the
sonar system.
The sensitivity level of the corner/center
sonar can be adjusted (higher or lower) in
the SONAR setting display. (See
“How to
use SETTING button” (P.4-13) for the
“Sonar” settings.)

SONAR INDICATORGUID-BF40EAC3-5D72-49FB-A713-20E51C407A89With the “Sonar Display” key ON in the
“Sonar” settings, when the corner/center
sonar detects obstacles near the bumper, a
tone will sound and the sonar indicator will
appear in the center display. When the rear
view monitor is displayed, the sonar
indicator will appear in the upper corner
of the display

The sonar indicators
*Aand*Bindicate
the position of the object and the distance

to the object with its color and rate of
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.4-13) for the“Sonar”
settings.) When the sonar indicator is off,
only a tone sounds when the sonar detects
obstacles.

SONAR SYSTEM OFF SWITCHGUID-ADA1633F-60D3-48D0-86BC-06AD618A342FThe 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
*1on 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.

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 PRECAUTIONSGUID-303F7865-3EEE-42BE-875A-2373C76593B9The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
Vacuum assisted brakesGUID-FB3BB3B2-604D-4649-8638-2E41A80E1853The 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 brakesGUID-435B5EB3-1F68-4B06-9333-CD2462DA6490When 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
during braking.
To dry brakes, drive the vehicle at a safe
speed while lightly tapping the brake pedal
to heat-up the brakes. Do this until the
brakes return to normal. Avoid driving thevehicle at high speeds until the brakes
function correctly.
PARKING BRAKE BREAK-INGUID-837DE698-6E89-4ED2-965C-C45C0822EC96Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced,
in order to assure the best braking
performance.
This procedure is described in the vehicle
service manual and can be performed by
an INFINITI retailer.
Using the brakesGUID-798BCC8C-1840-436E-B736-D4D16F071B12Avoid resting your foot on the brake pedal
while driving. This will cause overheating
of the brakes, wearing out the brake and
pads faster and reduce gas mileage.
To help save the brakes and to prevent the
brakes from overheating, reduce speed
and downshift to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performance
and could result in loss of vehicle control.
WARNING
.
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
. If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
