5-86Starting and driving

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 unit
OAinstalled be-
hind the windshield and a radar sensor lo-
cated on the front of the vehicle
OBto
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 re-
duce 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.
LSD3009
Starting and driving5-93

When passing another vehicle, the set
speed indicator
OBflashes when the ve-
hicle speed exceeds the set speed. The ve-
hicle ahead detection indicator turns off
when the area ahead of the vehicle is open.
When the pedal is released, the vehicle re-
turns to the previously set speed. Even
though your vehicle speed is set in the ICC
system, you can depress the accelerator
pedal when it is necessary to accelerate
your vehicle rapidly.
Cut-in detection
If a vehicle moves into your traveling lane
near your vehicle, the ICC system may in-
form 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 ve-
hicle or if another vehicle cuts in, the sys-
tem warns the driver with the chime and
ICC system display. Decelerate by depress-
ing the brake pedal to maintain a safe ve-
hicle 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 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
increasing. • When a vehicle cuts in near your vehicle.
The warning chime will not sound when:
• Your vehicle approaches other vehicles
that are parked or moving slowly.
• The accelerator pedal is depressed, over- riding 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 detect 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 ex-
ample, if a vehicle is being driven with
some damage).
LSD2895
5-108Starting and driving

•Always pay attention to the opera-
tion of the vehicle and be ready to
manually control the proper follow-
ing distance. The ICC system may not
be able to maintain the selected dis-
tance between vehicles (following
distance) or selected vehicle speed
under some circumstances.
• The system may not detect the ve-
hicle in front of you in certain road or
weather conditions. To avoid acci-
dents, never use the ICC system un-
der the following conditions:
– 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 ve-
hicle may go beyond the set ve-
hicle speed and frequent braking
may result in overheating the
brakes)
– On repeated uphill and downhill
roads –When traffic conditions make it dif-
ficult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
– Interference by other radar
sources
• In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. Al-
ways stay alert and avoid using the
ICC system where not recommended
in this warning 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 op-
erate 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 cover- ing 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 de-
tection 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 en-
tering the lane ahead may not be detected
until the vehicle has completely moved into
the lane.
5-110Starting and driving

When driving on some roads, such as wind-
ing, 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 ve-
hicle traveling ahead. This may cause the
radar system to decelerate or accelerate
the vehicle.
The detection of vehicles may also be af-
fected by vehicle operation (steering ma-
neuver 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 sound-
ing the chime unexpectedly. You will have to
manually control the proper distance away
from the vehicle traveling ahead.
System Temporarily Unavailable
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.Condition A
