1. System set display with vehicle ahead
2. System set display without vehicleahead
The driver sets the desired vehicle speed
based on the road conditions. The ICC sys-
tem maintains the set vehicle speed, simi-
lar to standard cruise control, as long as no
vehicle is detected in the lane ahead. The
ICC system displays the set speed. Vehicle detected ahead
When a vehicle is detected in the lane
ahead, the ICC system decelerates the ve-
hicle by controlling the throttle and apply-
ing the brakes to match the speed of a
slower vehicle ahead. The system then
controls the vehicle speed based on the
speed of the vehicle ahead to maintain the
driver selected distance.
NOTE:
• The stop lights of the vehicle come on
when braking is performed by the ICC
system.
• When the brake operates, a noise may be heard. This is not a malfunction.
When a vehicle ahead is detected, the ve-
hicle ahead detection indicator comes on.
The ICC system will also display the set
speed and selected distance. Vehicle ahead not detected
When a vehicle is no longer detected
ahead, the ICC system gradually acceler-
ates your vehicle to resume the previously
set vehicle speed. The ICC system then
maintains the set speed.
When a vehicle is no longer detected, the
vehicle ahead detection indicator turns off.
If a vehicle ahead appears during accelera-
tion to the set vehicle speed or any time the
ICC system is in operation, the system con-
trols the distance to that vehicle.
When a vehicle is no longer detected under
approximately 15 mph (24 km/h), the sys-
tem will be canceled.

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE 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 seri-
ous injury or death.
• The ICC system is primarily intended
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 auto-
matically 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 system. This system
does not correct careless, inattentive
or absentminded driving, or over-
come poor visibility in rain, fog, or
other bad weather. Decelerate the
vehicle speed by depressing the
brake pedal, depending on the dis-
tance to the vehicle ahead and the
surrounding circumstances 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.
The system will cancel once it judges
that the vehicle has come to a stand-
still and sound a warning chime. To
prevent the vehicle from moving, the
driver must depress the brake pedal.
• 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 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 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
difficult to keep a proper distance
between vehicles because of fre-
quent acceleration or
deceleration
– Interference by other radar
sources.

When the SET- switch is pushed under the
following conditions, the ProPILOT Assist
system cannot be set and the set vehicle
speed indicator
O1blinks for approxi-
mately 2 seconds:
• When traveling below 20 mph (32 km/h) and the vehicle ahead is not detected
• When the shif t lever is not in the D (Drive) position or B mode
• When the parking brake is applied
• When the brakes are operated by the driver • When the Vehicle Dynamic Control (VDC)
system is off. For additional information,
see “Vehicle Dynamic Control (VDC) sys-
tem” (P. 5-159).
• When the VDC system (including the trac- tion control system) is operating
• When a wheel is slipping
• When any door is open
• When the driver’s seat belt is not fastened
How to change the set vehicle
speed
The set vehicle speed can be adjusted.
To change to a faster cruising speed:
• Push and hold the RES+ switch. The set vehicle speed increases by approxi-
mately 5 mph (5 km/h).
• Push, then quickly release, the RES+ switch. Each time you do this, the set
speed increases by approximately 1 mph
(1 km/h).

Vehicle detected ahead
When a vehicle is detected in the lane
ahead, the ICC system decelerates the ve-
hicle by controlling the throttle and apply-
ing the brakes to match the speed of a
slower vehicle ahead. The ICC system then
controls the vehicle speed based on the
speed of the vehicle ahead to maintain the
driver selected distance.
NOTE:
• The stop lights of the vehicle come onwhen braking is performed by the ICC
system.
• When the brake is applied by the sys- tem, a noise may be heard. This is not a
malfunction.
When the ICC system detects a vehicle
ahead, the vehicle ahead detection indica-
tor and the speed control status indicator
(distance control mode) illuminates (solid
green
).
Vehicle ahead stops
When the vehicle ahead decelerates to
stop, your vehicle decelerates to a stand-
still. Once your vehicle stops, the ICC sys-
tem automatically applies the brakes to
keep the vehicle stopped. When your ve-
hicle is at a standstill, the “(RES+) Press to
start” message is displayed on the vehicle
information display.
NOTE:
When your vehicle stops for less than 3
seconds, your vehicle will automatically
follow the vehicle as it accelerates from a
stop. Vehicle ahead accelerates
When your vehicle is stopped and the ve-
hicle ahead begins to accelerate, push the
RES+ switch or lightly depress the accelera-
tor pedal. The ICC system starts to follow
the vehicle ahead.
Vehicle ahead not detected
When a vehicle is no longer detected
ahead, the ICC system gradually acceler-
ates your vehicle to resume the previously
set vehicle speed. The ICC system then
maintains the set speed.
When a vehicle is no longer detected, the
vehicle ahead detection indicator turns off
and the speed control status indicator
(maintain speed control mode) illuminates
(green outline
).
The ICC system gradually accelerates to
the set speed, but you can depress the
accelerator pedal to quickly accelerate.
When a vehicle is no longer detected and
your vehicle is traveling under approxi-
mately 15 mph (24 km/h), the ICC system
automatically cancels.

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.

tion display turn gray and a chime sounds
twice.
Intelligent Lane Intervention (I-LI)
When a curve or strong cross wind exceeds
the capabilities of the Steering Assist and
your vehicle approaches either the lef t or
the right side of the traveling lane, a warn-
ing chime sounds and the I-LI indicator
light (orange) on the instrument panel
flashes to alert the driver. Then, the I-LI sys-
tem automatically applies the brakes for a
short period of time to help assist the
driver to return the vehicle to the center of
the traveling lane. This action is in addition
to any Steering Assist actions.

AEB WITH PEDESTRIAN
DETECTION SYSTEM OPERATION1. Vehicle ahead detection indicator
2. AEB with Pedestrian Detection emer-gency warning indicator 3. AEB with Pedestrian Detection system
warning light
The AEB with Pedestrian Detection system
operates at speeds above approximately 3
mph (5 km/h). For the pedestrian detection
function, the AEB with Pedestrian Detec-
tion 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 AEB with Pedestrian Detec-
tion system will first provide a warning to
the driver by flashing the vehicle ahead de-
tection indicator and providing an audible
alert. In addition, the AEB with Pedestrian
Detection system applies partial braking. If
the driver applies the brakes quickly and
forcefully, but the AEB with Pedestrian De-
tection system detects that there is still the
possibility of a forward collision, the system
will automatically increase the braking
force.
If the risk of a collision becomes imminent
and the driver does not take action, the AEB
with Pedestrian Detection system issues
the second warning to the driver by flash-
ing the AEB with Pedestrian Detection
emergency warning indicator (red), provid-
ing an audible warning, and then automati-
cally applies harder braking.
LSD4076
5-124Starting and driving

If a risk of a forward impact with a pedes-
trian is detected, the AEB with Pedestrian
Detection system will provide a warning to
the driver by flashing the AEB with Pedes-
trian Detection emergency warning indica-
tor (red), provides an audible alert and the
system will apply partial braking. If the
driver applies the brakes quickly and force-
fully but the AEB with Pedestrian Detection
system detects that there is still the possi-
bility of a forward impact with a pedestrian,
the system will automatically increase the
braking force. If the risk of collision be-
comes imminent and the driver does not
take action, the AEB with Pedestrian Detec-
tion system automatically applies harder
braking.
NOTE:
The vehicle’s brake lights come on when
any braking is performed by the AEB
with Pedestrian Detection system.
Depending on vehicle speed and distance
to the vehicle or pedestrian ahead, as well
as driving and roadway conditions, the sys-
tem may help the driver avoid a forward
collision or may help mitigate the conse-
quences if a collision should be unavoid-
able. If the driver is handling the steering
wheel, accelerating or braking, the AEB withPedestrian 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 AEB with Pedestrian Detection sys-
tem has stopped the vehicle, the vehicle
will remain at a standstill for approximately
2 seconds before the brakes are released.
