Vehicle ahead detection indicator lightThe IBA system uses a distance sensor
*A
located below the front bumper to measure
the distance to the vehicle ahead. When
the system judges that your vehicle is
getting close to the vehicle ahead in the
traveling lane, the vehicle ahead detection
indicator light on the instrument panel
blinks and a warning chime sounds.
The IBA system will be turned on/off by
pushing the IBA OFF switch. The IBA OFF
indicator light display will illuminate when
the system is turned off.
PRECAUTIONS ON IBA SYSTEM
WARNING
.
The IBA system is not a collision
avoidance system. It is the driver’ s
responsibility to stay alert, drive safely
and be in control of the vehicle at all
times.
. As there is a performance limit, the
system may not provide a warning or
braking in certain conditions.
. The system will not detect the following
objects:
—Pedestrians, animals or obstacles in the roadway
—Oncoming vehicles in the same lane
. The system will not detect another
vehicle under the following conditions:
—When the sensor gets dirty and it is
impossible to detect the distance
from the vehicle ahead.
—When driving into a strong light (forexample, sunlight)
. The sensor generally detects the signals
returned from the reflectors on a vehicle
ahead. Therefore, the system may not
function properly under the following
conditions:
—When the reflectors of the vehicle
ahead are positioned high or close to
each other (including a small vehicle
such as motorcycles).
—When the sensor gets dirty and it isimpossible to detect the distance
from the vehicle ahead.
—When the reflectors on the vehicle
ahead are missing, damaged or
covered.
—When the reflectors of the vehicleahead are covered with dirt, snow or
Starting and driving5-75

system may not detect them. In these
instances the system may not be able to
warn the driver properly. Be sure to
check and clean the sensor regularly.
. Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
. Never place your foot under the brake
pedal when the IBA system turns on.
Your foot may be caught when the
system controls the brake.
. A sudden appearance of a vehicle in
front (for example, it abruptly cuts in)
may not be detected and the system may
not warn the driver soon enough.
. The system will be cancelled automati-
cally with a beep sound and the IBA
warning light will illuminate under the
following conditions:
—When the sensor window is dirty
—When the system malfunctions
If the IBA OFF indicator light illuminates
with a beep sound, pull off the road to a
safe location, stop the vehicle and turn the
engine off. Check to see if the sensor
window is dirty. If the sensor window is dirty, clean it with a soft cloth and restart
the engine. If the sensor window is not
dirty, restart the engine. If the IBA OFF
indicator light continues to illuminate even
if the IBA system is turned on, have the
system checked by an INFINITI retailer.

IBA system operation
The IBA system will function when your
vehicle is driven at speeds of approxi-
mately 10 MPH (15 km/h) or above, and
when the vehicle’s speed is approximately
10 MPH (15 km/h) faster than that of the
vehicle ahead.
To turn the system off/on, push and hold
the IBA OFF switch
*Bfor more than 1
second after starting the engine. When the
IBA OFF indicator light
*Aon the instru-
ment panel turns off and the IBA OFF
switch is pushed, the system will turn off
and the IBA OFF indicator light will
illuminate. When the IBA OFF switch is
Starting and driving5-77

5-78Starting and driving
pushed again, the system will turn on and
the IBA OFF indicator light will turn off.
The IBA system will remain in the last ON
or OFF state it was left in until it is
manually changed by pressing the IBA
OFF switch.
Illumination of the IBA OFF indicator light
without the warning chime sound is an
indication that the IBA system is tempora-
rily unavailable. It will occur under the
following conditions:
.When driving into a strong light (for
example, sunlight)
The IBA OFF indicator light will turn off
when the system returns to its normal
operating conditions.
For the sensor maintenance, see “Intelli-
gent Cruise Control (ICC) system (FULL
SPEED RANGE)” earlier in this section.
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. .
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.

The AWD warning light is located in the
meter.
The AWD warning light comes on when the
ignition switch is pushed to the ON
position. It turns off soon after the engine
is started.If any malfunction occurs in the AWD
system while the engine is running, the
warning light will come on.
The warning light may blink rapidly (about
twice per second) while trying to free a
stuck vehicle due to high power train oil
temperature. The driving mode may change
to two-wheel drive. If the warning light
blinks rapidly during operation, stop the
vehicle with the engine idling in a safe
place immediately. Then if the light goes
off after a while, you can continue driving.
A large difference between the diameters
of front and rear wheels will make the
warning light blink slowly (about once per
two seconds). Pull off the road in a safe
area, and idle the engine. Check that all
tire sizes are the same, tire pressure is
correct and tires are not worn.
If the warning light is blinking after the
above operation, have your vehicle
checked by an INFINITI retailer as soon as
possible.
WARNING
.
For AWD equipped vehicles, do not
attempt to raise two wheels off the ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
. Do not attempt to test an AWD equipped
vehicle on a 2-wheel dynamometer (such
as the dynamometers used by some
states for emissions testing) or similar
equipment even if the other two wheels
are raised off the ground. Make sure that
you inform the test facility personnel
that your vehicle is equipped with AWD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or
personal injury.
CAUTION
.Do not operate the engine on a free
roller when any of the wheels are raised.
. If the warning light comes on while
driving there may be a malfunction in

an INFINITI retailer as soon as possible.
. If the warning light remains on after the
above operation, have your vehicle
checked by an INFINITI retailer as soon
as possible.
. The power train may be damaged if you
continue driving with the warning light
blinking.

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 be placed in the P
(Park) position. Failure to do so could
cause the vehicle to move unexpectedly
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.
PARKING/PARKING ON HILLS

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

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 the
vehicle at high speeds until the brakes
function correctly.
PARKING BRAKE BREAK-IN
Break 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 brakes
Avoid 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 performanceand 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.
BRAKE ASSIST
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.
WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
driver’s responsibility to stay alert, drive
safely and be in control of the vehicle at all
times.
PREVIEW FUNCTION (Intelligent
Cruise Control system equipped
models)
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.
BRAKE ASSIST

.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:
— When the driver depresses the
accelerator pedal or the brake ped-
al.
— If the driver does not operate the
accelerator or brake pedal within
approximately 1 second.
SSD0338
. The sensor will not detect:
— Pedestrians or objects in the road-
way
— Oncoming vehicles in the same lane
— Motorcycles traveling offset in the
travel lane as illustrated
WARNING
. This system is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
driver’s responsibility to stay alert, drive
safely and be in control of the vehicle at all times.
. As there is a performance limit to the
Preview Function, never rely solely on
this system. This system does not
correct careless inattentive or absent-
minded driving, or overcome poor visi-
bility in rain, fog, or other bad weather.
Reduce vehicle speed by depressing the
brake pedal, in order to maintain a safe
distance between vehicles.
. The system may not detect the vehicle in
front of you in certain road or weather
conditions. The Preview Function may
not operate properly under the following
conditions. The vehicle is still driveable
under normal conditions and the Brake
Assist will operate.
—When rain, snow or dirt adhere to
the system sensor
—When strong light (for example, atsunrise or sunset) is directly shining
on the front of the vehicle
—Winding or hilly roads may causethe sensor to temporarily not detect
a vehicle in the same lane or may
detect objects or vehicles in other
lanes.
