When radar blockage is detected, the sys-
tem will be deactivated automatically. The
“Unavailable: Side Radar Obstruction”
warning message will appear in the vehicle
information display.
The systems are not available until the
conditions no longer exist.
The radar sensors may be blocked by tem-
porary ambient conditions such as splash-
ing water, mist or fog.
The blocked condition may also be caused
by conditions such as ice, snow, frost or dirt
obstructing the radar sensors.
NOTE:
If the BSW system stops working, the
RCTA system will also stop working.

The vehicle-to-vehicle distance control
mode is designed to maintain a selected
distance from the vehicle in front of you
and can reduce the speed to match a
slower vehicle ahead. The system will de-
celerate the vehicle as necessary and if the
vehicle ahead comes to a stop, the vehicle
decelerates to a standstill. However, the ICC
system can only apply up to 40% of the
vehicle’s total braking power.
This system should only be used when traf-
fic conditions allow vehicle speeds to re-
main fairly constant or when vehicle
speeds change gradually. If a vehicle
moves into the traveling lane ahead or if a
vehicle traveling ahead rapidly decelerates,
the distance between vehicles may be-
come closer because the ICC system can-
not decelerate the vehicle quickly enough.
If this occurs, the ICC system will sound a
warning chime and blink the system dis-
play to notif y the driver to take necessary
action.
The system will cancel and a warning
chime will sound if the speed is below ap-
proximately 15 mph (24 km/h) and a vehicle
is not detected ahead. The system will also
disengage when the vehicle goes above
the maximum set speed.For additional information, see “Approach
warning” (P. 5-81).
The following items are controlled in the
vehicle-to-vehicle distance control mode:
•
When there are no vehicles traveling ahead,
the vehicle-to-vehicle distance control
mode maintains the speed set by the driver.
The set speed range is between approxi-
mately 0 to 90 mph (30 to 144 km/h).
• When there is a vehicle traveling ahead, the vehicle-to-vehicle distance control
mode adjusts the speed to maintain the
distance, selected by the driver, from the
vehicle ahead. If the vehicle ahead comes
to a stop, the vehicle decelerates to a
standstill within the limitations of the sys-
tem. The system will cancel once it judges
a standstill with a warning chime.
• When the vehicle traveling ahead has moved out from its lane of travel, the
vehicle-to-vehicle distance control mode
accelerates and maintains vehicle speed
up to the set speed.
The ICC system does not control vehicle
speed or warn you when you approach
stationary and slow moving vehicles. You
must pay attention to vehicle operation to
maintain proper distance from vehicles
ahead when approaching toll gates or traf-
fic congestion. When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC system will adjust the speed
to maintain the distance, selected by the
driver, from the vehicle ahead. If the vehicle
ahead changes lanes or exits the freeway,
the ICC system will accelerate and main-
tain the speed up to the set speed. Pay
attention to the driving operation to main-
tain control of the vehicle as it accelerates
to the set speed.

1System set display with vehicle ahead
2System set display without vehicle
ahead
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 (25 km/h), the sys-
tem will be canceled.

Starting and driving5-79

NOTE:
The approach warning chime may sound
and the system display may blink when
the ICC 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
ICC sensor may detect these objects
when the vehicle is driven on winding
roads, narrow roads, hilly roads, or when
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 affected
by vehicle operation (steering maneuver or
driving position in the lane) or traffic or ve-
hicle condition (for example, if a vehicle is
being driven with some damage).
Automatic cancellation
A chime sounds under the following condi-
tions and the control is automatically can-
celed:
• When the vehicle ahead is not detectedand your vehicle is traveling below the
speed of 15 mph (25 km/h)
• When the system judges the vehicle is at a standstill • When the shif t lever is not in the D (Drive)
position, Manual mode or L (Low) range.
• When the parking brake system is applied
• When the VDC system is turned off
• When VDC operates
• When distance measurement becomes impaired due to adhesion of dirt or ob-
struction to the sensor
• When a wheel slips
• When the radar signal is temporarily interrupted
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.

The ProPILOT Assist system has the follow-
ing two functions:
1. Intelligent Cruise Control (ICC)
The ICC system can be set to one of two
cruise control modes:
• Conventional (fixed speed) cruise con-
trol mode: For cruising at a preset speed
NOTE:Steering Assist is not available in the
conventional (fixed speed) cruise control
mode.
•Vehicle-to-vehicle distance control
mode: The ICC system maintains a se-
lected distance from the vehicle in front
of you within the speed range of 0 to 90
mph (0 to 144 km/h) up to the set speed.
The set speed can be selected by the
driver between 20 to 90 mph (32 to 144
km/h). When the vehicle ahead slows to a
stop, your vehicle gradually decelerates
to a standstill. When the vehicle is
stopped, the ICC system maintains brak-
ing force to keep your vehicle stopped.
