WARNING
●This system is only an aid to assist the driver
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.
● This system will not adapt automatically to
road conditions. Do not use the system on
roads with sharp curves, or on icy roads, in
heavy rain or in fog.
The distance sensor will not detect the follow-
ing objects:
● Stationary and slow moving vehicles
● Pedestrians or objects in the roadway
● Oncoming vehicles in the same lane
● Motorcycles traveling offset in the travel
lane
WARNING
● As there is a performance limit to the dis-
tance control function, never rely solely on
the Distance Control Assist system. This
system does not correct careless, inatten-
tive or absent-minded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed by de-
pressing the brake pedal, depending on the
distance to the vehicle ahead and the sur-
rounding circumstances 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 condi-
tions. To avoid accidents, never use the Dis-
tance Control Assist system under the fol-
lowing conditions:
– On roads with sharp curves
– On slippery road surfaces such as on ice or snow, etc.
– During bad weather (rain, fog, snow, etc.)
– When strong light (for example, at sun- rise or sunset) is directly shining on the
front of the vehicle
– When rain, snow or dirt adhere to the sys- tem sensor – On steep downhill roads (frequent brak-
ing may result in overheating the brakes)
– On repeated uphill and downhill roads
● Do not use the Distance Control Assist sys-
tem if you are towing a trailer. The system
may not detect a vehicle ahead.
● In some road or traffic conditions, a vehicle
or object can unexpectedly come into the
sensor detection zone and cause automatic
braking. You may need to control the dis-
tance from other vehicles using the accelera-
tor pedal. Always stay alert and avoid using
the DCA system when it is not recommended
in this section.
Starting and driving5-55

The stoplights of the vehicle come on and the
brake pedal depresses when braking is per-
formed by the DCA system.
When the brake operates, a noise may be heard.
This is not a malfunction.
WARNING
●When the vehicle ahead detection indicator
light is not illuminated, system will not con-
trol or warn the driver.
● Never place your foot under the brake pedal.
Your foot may be caught when the system
controls the brake.
● Depending on the position of the accelerator
pedal, the system may not be able to assist
the driver to release the accelerator pedal
appropriately.
● If the vehicle ahead comes to a standstill,
the vehicle decelerates to a standstill within
the limitations of the system. The system
will release brake control with a warning
chime once it judges the vehicle is at a
standstill. To prevent the vehicle from mov-
ing, the driver must depress the brake pedal.
(The system will resume control automati-
cally once the system reaches 3 MPH (5
km/h)). Overriding the system :
The following driver’s operation overrides the
system operation.
●
When the driver depresses the accelerator
pedal even further while the system is mov-
ing the accelerator pedal upward, the DCA
system control of the accelerator pedal is
canceled.
● When the driver’s foot is on the accelerator
pedal, the brake control by the system is not
operated.
● When the driver’s foot is on the brake pedal,
neither the brake control nor the alert by the
system operates.
● When the Intelligent Cruise Control system is
set, the DCA system will be cancelled.
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that vehicle
or if another vehicle cuts in, the system warns
the driver with the chime and DCA system
display. Decelerate by depressing the brake
pedal to maintain a safe vehicle distance if:
● The chime sounds.
● The vehicle ahead detection indicator blinks.
The warning chime may not sound in some
cases when there is a short distance between
vehicles. Some examples are:
● When the vehicles are traveling at the same
speed and the distance between vehicles is
not changing
● When the vehicle ahead is traveling faster
and the distance between vehicles is in-
creasing
● When a vehicle cuts in near your vehicle
The warning chime will not sound when your
vehicle approaches vehicles that are parked or
moving slowly.

– When abruptly accelerating ordecelerating.
– On a steep downhill slope or on roads with sharp curves.
– When there is a highly reflective object near the vehicle ahead (i.e., being very
close to another vehicle, signboard, etc.)
– When you are towing a trailer.
● Depending on certain road conditions
(curved or beginning of a curve), vehicle con-
ditions (steering position or vehicle posi-
tion), or the preceding vehicle’s conditions
(position in lane, etc.), the system may not
function properly. The system may detect
highly reflective objects such as reflectors,
signs, white markers, and other stationary
objects on the road or near the traveling lane
and provide unnecessary warning.
● The system may not function in offset
conditions.
● The system may not function when the dis-
tance to the vehicle ahead is extremely
close. ●
The system is designed to automatically
check the sensor’s functionality. If the sen-
sor is covered with ice, a transparent or
translucent plastic bag, etc., the system may
not detect them. In these instances the sys-
tem may not be able to warn the driver prop-
erly. Be sure to check and clean the sensor
regularly.
● Excessive noise will interfere with the warn-
ing chime sound, and the chime may not be
heard.
● A sudden appearance of a vehicle in front
(i.e., it abruptly cuts in) may not be detected
and the system may not warn the driver soon
enough.
● The system will be cancelled automatically
with a beep sound and the IBA OFF indicator
light will illuminate under the following
conditions:
– When the sensor window is dirty
– When the system malfunctions If the IBA OFF indicator light
Ailluminates 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 with the IBA
OFF switch
B, have the system checked by an
INFINITI retailer.

mode is changed, a chime sounds and the lane
departure warning light (orange) flashes.
For the sensor maintenance, see “INTELLIGENT
CRUISE CONTROL (ICC) SYSTEM (FULL SPEED
RANGE)” earlier in this section.
The Intelligent Brake Assist (IBA) system warns
the driver by a warning light and chime when
there is a risk of a collision with the vehicle
ahead in the traveling lane and the driver must
take avoidance action immediately. The system
helps reduce the rear-end collision speed by
applying the brakes when the system judges
that the collision cannot be prevented.
The IBA system will function when your vehicle
is driven at speeds of approximately 10 MPH (15
km/h) and above, and when your vehicle is
driven at speeds approximately 10 MPH (15
km/h) faster than the vehicle ahead.

5-72Starting and driving

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 hydraulic
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, espe-
cially in sharp turns and at low speeds.
BRAKING PRECAUTIONS
The brake system has two separate hydraulic
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. How-
ever, greater foot pressure 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 weak-
ened 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 ser-
vice 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 performance and could result in
loss of vehicle control.
POWER STEERING
BRAKE SYSTEM
Starting and driving5-77

WARNING
●While driving on a slippery surface, be care-
ful when braking, accelerating or downshift-
ing. Abrupt braking or accelerating 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 responsibil-
ity 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 ve-
hicle 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 ve-
hicle is moving at approximately 20 MPH (32
km/h) or less.
● The pre-pressure function ceases when the
following conditions are met:
a) When the driver depresses the accel- erator pedal or the brake pedal.
b) If the driver does not operate the ac- celerator or brake pedal within ap-
proximately 1 second.
