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 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 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.

Starting and driving

-------------------------------------------------------------------------------------------------------------------------------------------------------------

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
will blink. The system will not be able to be

SYSTEM OPERATION

The FEB with Pedestrian Detection system
operates at speeds above approximately
3 mph (5 km/h). For the pedestrian detection
function, the FEB with Pedestrian Detection
system operates at speeds between 6 –
37 mph (10 – 60 km/h).

If a risk of a forward collision with a vehicle is
detected, the FEB with Pedestrian Detection
system will first provide a warning to the
driver by flashing the vehicle ahead detection
indicator and providing an audible alert. In
addition, the FEB with Pedestrian Detection
system pushes the accelerator pedal up, and
then the system applies partial braking. If the
driver applies the brakes quickly and force-
fully, but the FEB with Pedestrian Detection
system detects that there is still the possibility
of a forward collision, the system will auto-
matically increase the braking force.

If the risk of a collision becomes imminent
and the driver does not take action, the FEB
with Pedestrian Detection system issues the
second warning to the driver by flashing the
FEB with Pedestrian Detection emergency
warning indicator (red), providing an audible
warning, and then automatically applies
harder braking.

If a risk of a forward impact with a pedestrian
is detected, the FEB with Pedestrian Detec-
tion system will provide a warning to the
driver by flashing the FEB with Pedestrian
Detection emergency warning indicator (red),
provides an audible alert and the system will
apply partial baking. If the driver applies the
brakes quickly and forcefully but the FEB
with Pedestrian Detection system detects
that there is still the possibility of a forward
impact with a pedestrian, the system will au-
tomatically increase the braking force. If the
risk of collision becomes imminent and the
driver does not take action, the FEB with
Pedestrian Detection system automatically
applies harder braking.

NOTE:

The vehicle’s brake lights come on when any
braking is performed by the FEB with Pedes-
trian Detection system.

Depending on vehicle speed and distance to
the vehicle or pedestrian ahead, as well as
driving and roadway conditions, the system
may help the driver avoid a forward collision
or may help mitigate the consequences if a
collision should be unavoidable. If the driver is
handling the steering wheel, accelerating or
braking, the FEB with Pedestrian Detection
system will function later or will not function.

The automatic braking will cease under the
following conditions:

∙ When the steering wheel is turned to

avoid a collision.

∙ When the accelerator pedal is depressed.

∙ When there is no longer a vehicle or a

pedestrian detected ahead.

If the FEB with Pedestrian Detection system
has stopped the vehicle, the vehicle will re-
main at a standstill for approximately 2 sec-
onds before the brakes are released.
