RCTA SYSTEM LIMITATIONS
WARNING
Listed below are the system limita-
tions for the RCTA system. Failure to
operate the vehicle in accordance
with these system limitations could
result in serious injury or death.
.Always check surroundings and
turn to check what is behind you
before backing up. The radar
sensors detect approaching
(moving) vehicles. The radar sen-
sors cannot detect every object
such as:
— Pedestrians, bicycles, motor-
cycles, animals or child-oper-
ated toy vehicles
— A vehicle that is passing at speeds greater than approxi-
mately 19 MPH (30 km/h)
— A vehicle that is passing at speeds lower than approxi-
mately 5 MPH (8 km/h)
. The radar sensors may not detect
approaching vehicles in certain
situations:

— Illustration: When a vehicle
parked next to you obstructs
the beam of the radar sensor.
— Illustration
: When the vehi-
cle is parked in an angled
parking space.
— Illustration
: When the vehi-
cle is parked on inclined
ground.
— Illustration
: When an ap-
proaching vehicle turns into
your vehicle’s parking lot aisle.
— Illustration
: When the angle
formed by your vehicle and
approaching vehicle is small
. The following conditions may re-
duce the ability of the radar to
detect other vehicles:
— Severe weather
— Road spray
— Ice/frost/dirt build-up on the
vehicle
. Do not attach stickers (including
transparent material), install ac-
cessories or apply additional
paint near the radar sensors.
These conditions may reduce the
ability of the radar to detect other
vehicles .
Excessive noise (e.g. audio sys-
tem volume, open vehicle win-
dow) will interfere with the
chime sound, and it may not be
heard.JVS0172X

The ProPILOT assist system is intended to
enhance the operation of the vehicle
when following a vehicle traveling in the
same lane and direction.
The ProPILOT assist system uses a multi-
sensing front camera
installed behind
the windshield and a radar sensor located
on the front of the vehicle
to measure
the distance to the vehicle ahead in the
same lane and to monitor the lane
markers. If the vehicle detects a slower
moving vehicle ahead, the system will
reduce the vehicle speed so that your
vehicle follows the vehicle in front at the
selected distance. The system will also
help keep the vehicle centered in the
traveling lane when clear lane markings are detected.
Starting and driving5-65

Cut-in detection
If a vehicle moves into your traveling lane
near your vehicle, the ICC system may
inform the driver by flashing the vehicle
ahead detection indicator.
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 ICC system display. Decelerate by
depressing the brake pedal to maintain a
safe vehicle distance if:
.The chime sounds.
. The vehicle ahead detection indicator
and set distance indicator blink.
. You judge it necessary to maintain a
safe distance.
The warning chime may not sound in
some cases when there is a short dis-
tance between vehicles. Some examples
are:
. When the vehicles are traveling at the
same speed and the distance be-
tween vehicles is not changing.
. When the vehicle ahead is traveling
faster and the distance between ve-
hicles is increasing.
. When a vehicle cuts in near your
vehicle. The warning chime will not sound when:
.
Your vehicle approaches other vehi-
cles that are parked or moving slowly.
. The accelerator pedal is depressed,
overriding the system.
NOTE:
The approach warning chime may
sound and the system display may
flash when the radar sensor detects
objects on the side of the vehicle or on
the side of the road. This may cause the
ICC system to decelerate or accelerate
the vehicle. The radar sensor may de-
tect these objects when the vehicle is
driven on winding, narrow, or hilly roads
or when the vehicle is entering or
exiting a curve. In these cases, you will
have to manually control the proper
distance ahead of your vehicle.
Also, the sensor sensitivity can be af-
fected by vehicle operation (steering
maneuver or driving position in the
lane) or traffic or vehicle conditions
(for example, if a vehicle is being driven
with some damage).
Acceleration when passing
When the ICC system is engaged above
44 mph (70 km/h) and following a slower
vehicle (below ICC set speed), and the
turn signal is activated to the left, the ICC
system will automatically start to accel-
erate the vehicle to help initiate passing
on the left and will begin to reduce the
distance to vehicle directly ahead. Only
the left side turn signal operates this
feature. As the driver steers the vehicle
and moves into the passing lane, if no
vehicle is detected ahead the ICC system
will continue to accelerate to the ICC
system set speed. If another vehicle is
detected ahead, then the vehicle will
accelerate up to the following speed of
that vehicle. If the vehicle is not steered
into the left lane to pass, the acceleration
will stop after a short time and regain the
set following distance. Acceleration can
be stopped at any point by depressing
the brake pedal or the CANCEL switch on
the steering wheel.
ICC system limitations
WARNING
Listed below are the system limita-
tions for the ICC system. Failure to
operate the vehicle in accordance
Starting and driving5-79

5-80Starting and driving
with these system limitations could
result in serious injury or death:
.The ICC system is primarily in-
tended for use on straight, dry,
open roads with light traffic. It is
not advisable to use the ICC
system in city traffic or congested
areas.
. The ICC 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 distance control function,
never rely solely on the ICC sys-
tem. This system does not correct
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
pedal, depending on the distance
to the vehicle ahead and the
surrounding circumstances in or-
der to maintain a safe distance
between vehicles.
. When the ICC system automati-
cally brings the vehicle to a stop, your vehicle can automatically
accelerate if the vehicle is
stopped for less than approxi-
mately 3 seconds. Be prepared
to stop your vehicle if necessary.
. Always pay attention to the op-
eration 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.
. The system may not detect the
vehicle in front of you in certain
road or weather conditions. To
avoid accidents, never use the ICC
system under the following con-
ditions:
— On roads with heavy, high-
speed traffic or 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 bumper around the
distance sensor — On steep downhill roads (the
vehicle may go beyond the set
vehicle speed and frequent
braking may result in over-
heating the brakes)
— On repeated uphill and down- hill roads
— When traffic conditions make it difficult to keep a proper
distance between vehicles be-
cause of frequent accelera-
tion or deceleration
— Interference by other radar sources.
. In some road or traffic conditions,
a vehicle or object can unexpect-
edly come into the sensor detec-
tion zone and cause automatic
braking. Always stay alert and
avoid using the ICC system where
not recommended in this warn-
ing section.
The ICC system will not detect the
following objects:
. Stationary or 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 radar sensor cannot properly
detect a vehicle ahead and the system
may not operate properly:
. When the sensor detection is reduced
(conditions such as rain, snow, fog,
dust storms, sandstorms, and road
spray from other vehicles)
. Driving on a steep downhill slope or
roads with sharp curves
. Driving on a bumpy road surface, such
as an uneven dirt road
. If dirt, ice, snow or other material is
covering the radar sensor area
. A complicated-shaped vehicle such as
a car carrier trailer or flatbed truck/
trailer is near the vehicle ahead.
. Interference by other radar sources
. When excessively heavy baggage is
loaded in the rear seat or cargo area
of your vehicle.
The ICC system is designed to automati-
cally check the radar sensor’s operation
within the limitations of the system
The detection zone of the radar sensor is
limited. A vehicle ahead must be in the
detection zone for the ICC system to
maintain the selected distance from the
vehicle ahead. 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 occurs, the ICC system may warn
you by blinking the system indicator and
sounding the chime. The driver may have
to manually control the proper distance
away from the vehicle traveling ahead.
The ICC system (with ProPILOT assist)
uses a multi-sensing front camera. The
following are some conditions in which
the camera may not properly detect a
vehicle and detection of a vehicle ahead
may be delayed:
.
Poor visibility (conditions such as rain,
snow, fog, dust storms, sandstorms,
and road spray from other vehicles)
. The camera area of the windshield is
fogged up or covered with dirt, water
drops, ice, snow, etc.
. Strong light (for example, sunlight or
high beams from oncoming vehicles)
enters the front camera
. A sudden change in brightness occurs
(for example, when the vehicle enters
or exits a tunnel or shaded area or lightning flashes)

When driving on some roads, such as
winding, hilly, curved, narrow roads, or
roads which are under construction, the
radar sensor may detect vehicles in a
different lane, or may temporarily not
detect a vehicle traveling ahead. This
may cause the ICC system to decelerate
or accelerate the vehicle.
The detection of vehicles may also be
affected by vehicle operation (steering
maneuver or traveling position in the
lane, etc.) or vehicle condition.
If this occurs, the ICC system may warn
you by blinking the system indicator and
sounding the chime unexpectedly. You
will have to manually control the proper
distance away from the vehicle traveling
ahead.
Automatic cancellation
The following are conditions in which the
ICC system may be temporarily unavail-
able. In these instances, the ICC system
may not cancel and may not be able to
maintain the selected following distance
from the vehicle ahead.
