DCA SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations of
the DCA system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious injury or
death.
∙ This system will not adapt automaticallyto road conditions. Do not use the system
on roads with sharp curves, or on icy
roads, in heavy rain or in fog.
∙ The DCA system will not apply brake control while the driver’s foot is on the
accelerator pedal.
∙ As there is a performance limit to the dis- tance control function, never rely solely
on the DCA system. This system does not
correct careless, inattentive or absent-
minded driving, or overcome poor visibil-
ity in rain, fog, or other bad weather. De-
celerate the vehicle speed by depressing
the brake pedal, depending on the dis-
tance to the vehicle ahead and the sur-
rounding circumstances in order to main-
tain a safe distance between vehicles. ∙ The system may not detect the vehicle in
front of you in certain road or weather
conditions. To avoid accidents, never use
the DCA 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.
– On off-road surfaces such as on sand or rock, etc.
– During bad weather (rain, fog, snow, etc.)
– When rain, snow or dirt adhere to the sensor area of the front bumper
– On steep downhill roads (frequent braking may result in overheating the
brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it diffi- cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
– When towing a trailer or other vehicle
– Interference by other radar sources ∙ In some road or traffic conditions, a ve-
hicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. You may need to con-
trol the distance from other vehicles us-
ing the accelerator pedal. Always stay
alert and avoid using the DCA system
when it is not recommended in this
section.
The radar sensor will not detect the following
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 detect the signals: ∙ When the snow or road spray from trav- eling vehicles reduces the sensor’s visibil-
ity
∙ When excessively heavy baggage is loaded in the rear seat or the luggage
room of your vehicle

DCA DRIVING SITUATIONS
The detection zone of the sensor is limited. A
vehicle ahead must be in the detection zone
for the system to operate.
A vehicle ahead may move outside of the
detection zone due to its position within the
same lane of travel. Motorcycles may not be
detected in the same lane ahead if they are
traveling offset from the center line of the
lane. A vehicle that is entering the lane ahead
may not be detected until the vehicle has
completely moved into the lane.If this oc-
curs, the system may warn you by blinking the system indicator and sounding the
chime. The driver may have to manually con-
trol the proper distance away from the ve-
hicle traveling ahead.
DCA Detection Zone
SSD0252
Starting and driving5-141

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the sensor may
detect vehicles in a different lane, or may
temporarily not detect a vehicle traveling
ahead. This may cause the system to work
inappropriately.The detection of vehicles may also be af-
fected by vehicle operation (steering maneu-
ver or traveling position in the lane, etc.) or
vehicle condition.
If this occurs, the system
may warn you by blinking the system indica-
tor and sounding the chime unexpectedly.
You will have to manually control the proper
distance away from the vehicle traveling
ahead.SYSTEM TEMPORARILY
UNAVAILABLE
Condition A:
Under the following conditions, the DCA sys-
tem is automatically canceled. The chime will
sound and the DCA system switch indicator

warning light (orange) will come on and the
“Unavailable: Front Radar Blocked” warning
will appear.Action to take:
If the warning light comes on, park the vehicle
in a safe place, press the park button to place
the vehicle in the P (Park) position and turn
the engine off. When the radar signal is tem-
porarily interrupted, clean the sensor area
and restart the engine. If the “Unavailable:
Front Radar Blocked” warning continues to
be displayed, have the DCA system checked.
It is recommended you visit and INFINITI
retailer for this service.
When driving on roads with limited road
structures or buildings (for example, long
bridges, deserts, snow fields, driving next to
long walls) the system may illuminate the sys-
tem warning light (orange) and display the
“Unavailable Front Radar Blocked” message.
Action to take:
When the above conditions no longer exist,
the DCA system will resume automatically.
Condition C:
When the DCA system is not operating prop-
erly, the chime sounds, the DCA system

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the RAB system
could result in serious injury or death.
∙ The RAB system is a supplemental aid tothe driver. It is not a replacement for
proper driving procedures. Always use
the side and rear mirrors and turn and
look in the direction you will move before
and while backing up. Never rely solely on
the RAB system. It is the driver’s respon-
sibility to stay alert, drive safely, and be
in control of the vehicle at all times.
∙ There is a limitation to the RAB system capability. The RAB system is not effec-
tive in all situations.
The RAB system can assist the driver when
the vehicle is backing up and approaching
objects directly behind the vehicle. The RAB system detects obstacles behind
the vehicle using the parking sensors
1lo-
cated on the rear bumper.
NOTE:
You can temporarily cancel the sonar func-
tion in the vehicle, but the RAB system will
continue to operate. For additional informa-
tion, please refer to “Front and rear sonar

RAB SYSTEM OPERATION
When the shift lever is in the R (Reverse)
position and the vehicle speed is less than
approximately 9 mph (15 km/h), the RAB
system operates.
If a risk of a collision with an obstacle is
detected when your vehicle is backing up, the
RAB system warning indicator will flash in the
vehicle information display, a red frame will
appear in the center display (for vehicles with
the Intelligent Around View Monitor system),
and the system will chime three times. The
system will then automatically apply the
brakes. After the automatic brake applica-
tion, the driver must depress the brake pedal
to maintain brake pressure.
NOTE:∙ The brake lights of the vehicle come on
when braking is performed by the RAB
system.
∙ When the brakes operate, a noise may be
heard. This is not a malfunction.

∙ When the vehicle approaches an obstaclewhile the accelerator or brake pedal is
depressed, the function may not operate
or the start of operation may be delayed.
The RAB system may not operate or may
not perform sufficiently due to vehicle
conditions, driving conditions, the traffic
environment, the weather, road surface
conditions, etc. Do not wait for the sys-
tem to operate. Operate the brake pedal
by yourself as soon as necessary.
∙ If it is necessary to override RAB opera- tion, strongly press the accelerator
pedal.
∙ Always check your surroundings and turn to check what is behind you before and
while backing up. The RAB system de-
tects stationary objects behind the ve-
hicle. The RAB system does not detect
the following objects:
– Moving objects
– Low objects
– Narrow objects
– Wedge-shaped objects
– Objects close to the bumper (less than approximately 1 ft [30 cm]) – Objects that suddenly appear
– Thin objects such as rope, wire, chain,
etc.
∙ The RAB system may not operate for the following obstacles:
– Obstacles located high off the ground
– Obstacles in a position offset from your vehicle
– Obstacles, such as spongy materials or snow, that have soft outer surfaces
and can easily absorb a sound wave
∙ The RAB system may not operate in the following conditions:
– There is rain, snow, ice, dirt, etc., at- tached to the sonar sensors.
– A loud sound is heard in the area around the vehicle.
– The surface of the obstacle is diagonal to the rear of the vehicle.
∙ The RAB system may unintentionally op- erate in the following conditions:
– There is overgrown grass in the area around the vehicle. – There is a structure (e.g., a wall, toll
gate equipment, a narrow tunnel, a
parking lot gate) near the side of the
vehicle.
– There are bumps, protrusions, or man- hole covers on the road surface.
– The vehicle drives through a draped flag or a curtain.
– There is an accumulation of snow or ice behind the vehicle.
– An ultrasonic wave source, such as an- other vehicle’s sonar, is near the
vehicle.
∙ Once the automatic brake control oper- ates, it does not operate again if the ve-
hicle approaches the same obstacle.
∙ The automatic brake control can only op- erate for a short period of time. There-
fore, the driver must depress the brake
pedal.
∙ In the following situations, the RAB sys- tem may not operate properly or may not
function sufficiently:
– The vehicle is driven in bad weather (rain, fog, snow, etc.).
