MessagePossible causes/consequences and solutions
[Check Brake Fluid Level]There is insufficient brake fluid in the brake fluid reservoir.
In addition, the redwarning light lights up in the combination meter and a warning tone sounds.
1. Pull over and stop the vehicle safely as soon as possible, paying attention to road and traffic conditions. Do not continue driving under any circumstances.
2. Secure the vehicle against rolling away.
3. Check the brake fluid level. If brake fluid is necessary, add fluid and have the system checked. It is recommended you visit an INFINITI
retailer for this service. See Brake fluidin the8. Do-it-yourself section.
4. If the brake fluid level is correct, have the warning system checked. It is recommended you visit an INFINITI retailer for this service.
WARNING•Your brake system may not be working properly if the warning light is on. Driving could be dangerous. If you judge it to be safe, drive
carefully to the nearest service station for repairs. Otherwise, have your vehicle towed because driving it could be dangerous.
•Pressing the brake pedal with the engine stopped and/or low brake fluid level may increase your stopping distance and braking will
require greater pedal effort as well as pedal travel.
•If the brake fluid level is below the minimum or MIN mark on the brake fluid reservoir, do not drive until the brake system has been
checked. It is recommended you visit an INFINITI retailer for this service.
[Check Brake Pad Wear] The brake pads/linings have reached their wear limit.
It is recommended you visit an INFINITI retailer.

RADAR MAINTENANCE
The two radar sensor unitsAfor the BSW
system are located near the rear bumper. Al-
ways keep the area near the radar sensors
clean.
The radar sensors may be blocked by temporary
ambient conditions such as splashing water,
mist or fog.
The blocked condition may also be caused by
objects such as ice, frost or dirt obstructing the
radar sensors.
Check for and remove objects obstructing the
area around the radar sensors.
Do not attach stickers (including transparent
material), install accessories or apply addi-
tional paint near the radar sensors. Do not strike or damage the area around the
radar sensors. It is recommended you consult
an INFINITI retailer if the area around the radar
sensors is damaged due to a collision.

Cruise control maintains a constant road speed
for you. It brakes automatically in order to avoid
exceeding the set speed. You must select a
lower gear in good time on long and steep
downhill gradients, especially if the vehicle is
laden or towing a trailer.WARNING
For vehicles with automatic transmission, you
need to have selected manual drive program M
(see
Manual drive program earlier in this sec-
tion). By doing so, you will make use of the
braking effect of the engine. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
Use cruise control only if road and traffic con-
ditions are appropriate for maintaining a steady
speed for a prolonged period. You can set the
cruise control at any road speed above 20 MPH
(30 km/h).
The speed indicated in the speedometer may
differ slightly from the set speed.

CRUISE CONTROL
5-44Starting and driving

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 distance warning
light. Decelerate by depressing the brake pedal
to maintain a safe vehicle distance if:
•The chime sounds.
•The distance warning light is illuminated.
The warning chime may not sound and the
distance warning light may not illuminate 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. In this case, the distance
warning light will be on.
•When the vehicle ahead is traveling faster
and the distance between vehicles is increas-
ing.
•When a vehicle cuts in near your vehicle
•The warning chime will not sound and the
distance warning light will not illuminate
when: – The vehicle approaches other vehicles that are parked or moving slowly. – The accelerator pedal is depressed, over-
riding the system.
Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driving
position in the lane) or traffic or vehicle condi-
tion (for example, if a vehicle is being driven
with some damage).
Automatic cancellation
A chime sounds and the message [ICC off] is
displayed in the vehicle information display for
5 seconds under the following conditions and
the control is automatically canceled.
•The electric parking brake is applied.
•The VDC intervenes or the VDC is deacti-
vated.
•The P (Park), R (Reverse) or N (Neutral)
position is engaged.
•The cruise control lever is pulled in order to
pull away but the front passenger door or
one of the rear doors is open.
•The vehicle is skidding or a wheel slips.
•Active Park Assist is activated.
ICC LIMITATIONS
WARNING
Listed below are the system limitations for the
ICC system. Failure to operate the vehicle in
accordance with these system limitations
could result in serious injury or death.
•This system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is the driver’s responsi-
bility to stay alert, drive safely and be in
control of the vehicle at all times.
•The system is primarily intended for use on
straight, dry, open roads with light traffic. It
is not advisable to use the system in city
traffic or congested areas.
•This system will not adapt automatically to
road conditions. This system should be
used in evenly flowing traffic. Do not use the
system on roads with sharp curves, or on icy
roads, in heavy rain or in fog.
•As there is a performance limit to the dis-
tance control function, never rely solely on
the ICC system. This system does not cor-
rect careless, inattentive or absent-minded
driving, or overcome poor visibility in rain,
fog, or other bad weather. Decelerate the
vehicle speed by depressing the brake
5-54Starting and driving

pedal, depending on the distance to the ve-
hicle ahead and the surrounding circum-
stances in order to maintain a safe distance
between vehicles.
•If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system. Once the ve-
hicle is stationary, it remains stationary and
you do not need to depress the brake pedal.
•Always pay attention to the operation of the
vehicle and be ready to manually control the
proper following distance. The ICC system
may not be able to maintain the selected
distance between vehicles (following dis-
tance) or selected vehicle speed under
some circumstances.
•Normally when controlling the distance to a
vehicle ahead, this system automatically
accelerates or decelerates your vehicle ac-
cording to the speed of the vehicle ahead. If
required, depress the accelerator to prop-
erly accelerate your vehicle when accelera-
tion is required for a lane change. Depress
the brake pedal when deceleration is re-
quired to maintain a safe distance to the
vehicle ahead due to its sudden braking or if
a vehicle cuts in. Always stay alert when
using the ICC system.
•The system may not detect the vehicle in
front of you in certain road or weather con-
ditions. To avoid accidents, never use the
ICC 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.).
– When rain, snow or dirt adhere to the
system sensor.
– On steep downhill roads (the vehicle
may go beyond the set vehicle speed and
frequent braking may result in overheat-
ing the brakes).
– On repeated uphill and downhill roads.
– When traffic conditions make it difficult
to keep a proper distance between ve-
hicles because of frequent acceleration
or deceleration.
– If there is interference by other radar
sources.
•Do not use the ICC system 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 accel-
erator pedal. Always stay alert and avoid
using the ICC system when it is not recom-
mended in this section.
•The distance sensor will not detect the fol-
lowing 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.
The following are some conditions in which the
sensor cannot properly detect a vehicle ahead
and the system may not operate properly:
•When the snow or road spray from traveling
vehicles reduces the sensor’s visibility.
•When excessively heavy baggage is loaded
in the rear seat or the luggage room of your
vehicle.
The ICC system is designed to automatically
check the sensor’s operation within the limita-
tion of the system. When the sensor is covered
with dirt or is obstructed, the system will auto-
matically be canceled. If the sensor is covered
with ice, a transparent or translucent vinyl bag,
etc., the ICC system may not detect them. In
Starting and driving5-55

these instances, the ICC system may not cancel
and may not be able to maintain the selected
following distance from the vehicle ahead. Be
sure to check and clean the sensor regularly.
TIPS FOR DRIVING WITH THE ICC
SYSTEM
General notes
The following contains descriptions of certain
road and traffic conditions in which you must be
particularly attentive. In such situations, brake
if necessary. The ICC system is then deactivated
Cornering, entering and exiting a
bend
The ability of the ICC system to detect vehicles
when cornering is limited. Your vehicle may
brake unexpectedly or late.
Vehicles that are not driving in the
middle of their lane
The ICC system may not detect vehicles which
are not driving in the middle of their lane. The
system will not brake for or keep a following
distance to the car which is offset.

SYSTEM TEMPORARILY UNAVAILABLE
When the radar sensor area is covered with dirt
or is obstructed, the system will automatically
be canceled. If the radar sensor area is covered
with ice, a transparent or translucent vinyl bag,
etc., the ICC system may not detect them. In
these instances, the ICC system may not cancel
and may not be able to maintain the selected
following distance from the vehicle ahead.

Autonomous braking function
If the driver does not react to the distance
warning signal in a critical situation, the FEB
system can assist with the autonomous braking
function
The autonomous braking function can help the
driver to avoid an accident or reduces the
effects of an accident.
The autonomous braking function is available in
the following speed ranges:
•4–125 MPH (7-200 km/h) for moving vehicles
•4–30 MPH (7 -50 km/h) for stationary ve-
hicles
Adaptive brake assist function
Adaptive brake assist function provides braking
assistance in hazardous situations at speeds
above 4MPH (7 km/h). It uses radar sensor
technology to assess the traffic situation.
If the system detects a risk of collision with the
vehicle in front, it calculates the braking force
necessary to avoid a collision. If you apply the
brakes forcefully, the adaptive brake assist
function will automatically increase the braking
force to a level suitable for the traffic condi-
tions.
If the adaptive brake assist function activates,
keep the brake pedal depressed until the emer-
gency braking situation is over. ABS prevents
the wheels from locking.
The brakes will work normally again if:
•You release the brake pedal.
•There is no longer any danger of a collision.
•No obstacle is detected in front of your
vehicle.
The brake assist function is then deactivated. At high speeds, the adaptive brake assist func-
tion is capable of reacting to moving objects
that have already been detected as such at
least once over the period of observation.
Up to a speed of approximately 45 MPH (70
km/h), the adaptive brake assist function reacts
to stationary vehicles.

FEB SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for the
FEB system. Failure to operate the vehicle in
accordance with these system limitations
could result in serious injury or death.
•The FEB system cannot detect all vehicles
under all conditions.
•The radar sensor does not detect the follow-
ing objects:– Pedestrians or animals
– Oncoming vehicles
– Crossing vehicles
•The radar sensor has some performance
limitations. For stationary vehicles, the FEB
system will not function when the vehicle is
driven at speeds over:
– Approximately 31 MPH (50 km/h) for the
Autonomous braking function.
•The radar sensor may not detect a vehicle
ahead in the following conditions:
– Dirt, ice, snow or other material covering
the radar sensor.
– Interference by other radar sources.
– Snow or heavy rain.
– If the vehicle ahead is narrow (e.g. mo-
torcycle). –
If the vehicle ahead is in a different lane.
– Under strong radar reflections, for ex-
ample, in a multi-level parking garage.
– New vehicle or after a maintenance of the
FEB system. For additional information,
see Break-in schedule later in this sec-
tion
– When driving on a steep downhill slope
or roads with sharp curves.
– When towing a trailer.
•In some road or traffic conditions, the FEB
system may intervene unnecessarily or give
an unnecessary warning. Always pay care-
ful attention to the traffic situation. Do not
rely solely on the distance warning function
and terminate the intervention if necessary.
•Braking distances increase on slippery sur-
faces.
•The system is designed to automatically
check the sensor’s functionality, within cer-
tain limitations. The system may not detect
some forms of obstruction of the sensor
area such as ice, snow, stickers, for ex-
ample. In these cases, the system may not
be able to warn the driver properly. Be sure
that you check, clean and clear the sensor
area regularly.
•Excessive noise will interfere with the warn-
ing chime sound, and the chime may not be
heard.
SYSTEM TEMPORARILY UNAVAILABLE
If the FEB stops working due to a malfunction or
some other reason, one of the following three
messages will be displayed in the vehicle infor-
mation display.
•[Emergency Brake Currently Unavailable See
Operator’s Manual]
•[Emergency Brake Inoperative]
