matically.
. When your vehicle is at a standstill for
more than approximately 3 seconds
and the vehicle ahead begins to
accelerate, push up the RES+ switch
or lightly depress the accelerator ped-
al. The ICC system starts to follow the
vehicle ahead.
. Always check surroundings before
restarting the vehicle.
. For vehicles equipped with ProPILOT
Assist with Navi-link and only when on
a limited access freeway (as identified
in the navigation map data):
— The time the vehicle can remain
stopped and automatically restart
is extended from 3 seconds to 30
seconds.
— If a vehicle ahead cuts in or out of the lane ahead, the vehicle may not
automatically start when the traffic
ahead begins to move. You need to
push up the RES+ switch or lightly
depress the accelerator pedal to
follow the vehicle directly ahead
when it is safe to do so.
. When no vehicle is detected ahead
within the driver selected distance, the
vehicle travels at the speed set by the
driver. The speed must be above 20
MPH (30 km/h) to use this function. NOTE:
Even if the Automatic Emergency Brak-
ing (AEB) setting is turned off by the
driver using the “Settings” menu in the
vehicle information display, AEB will be
automatically turned on when ICC is
used.
2. Steering Assist
The Steering Assist function helps the
driver to keep the vehicle centered within
the traveling lane.
When there is no vehicle ahead, Steering
Assist is not available at speeds under 37
MPH (60 km/h).

.Always drive carefully and atten-
tively when using the ICC system.
Read and understand the Owner’s
Manual thoroughly before using
the ICC system. To avoid serious
injury or death, do not rely on the
system to prevent accidents or to
control the vehicle’s speed in
emergency situations. Do not
use the ICC system except in
appropriate road and traffic con-
ditions.
ICC system operation
The ICC system 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 sys-
tem decelerates 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
traffic conditions allow vehicle speeds to
remain fairly constant or when vehicle
speeds change gradually. If a vehicle
moves into the traveling lane ahead or if
a vehicle traveling ahead rapidly decele-
rates, the distance between vehicles may become closer because the ICC system
cannot decelerate the vehicle quickly
enough. If this occurs, the ICC system
sounds a warning chime and blinks the
system display to notify the driver to take
necessary action.
The ICC system cancels and a warning
chime sounds if the speed is below
approximately 15 MPH (25 km/h) and a
vehicle is not detected ahead. For ProPI-
LOT Assist with Navi-link equipped vehi-
cles on a limited access freeway as
identified in the navigation map data,
the ICC system cancels and a warning
chime sounds if your vehicle is at a
standstill for more than approximately 3
seconds and a vehicle is not detected
ahead.
The ICC system operates as follows:
.
When there are no vehicles traveling
ahead, the ICC system maintains the
speed set by the driver. The vehicle set
speed range is between approxi-
mately 20 and 90 MPH (30 and 144
km/h).
. When there is a vehicle traveling
ahead, the ICC system adjusts the
speed to maintain the distance, se-
lected by the driver, from the vehicle
ahead. If the vehicle ahead comes to a
stop, the vehicle decelerates to a
standstill. Once your vehicle stops, the ICC system keeps the vehicle
stopped.
. When the vehicle traveling ahead
moves to a different traveling lane,
the ICC system accelerates and main-
tains 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
traffic congestion.
5-100Starting and driving
WAF0580XSystem set display — vehicle ahead*
Vehicle detected ahead:
When a vehicle is detected in the lane
ahead, the ICC system decelerates the
vehicle by controlling the throttle and
applying the brakes to match the speed
of a slower vehicle ahead. The ICC system
then adjusts the vehicle speed based on
the speed of the vehicle ahead to main-
tain the driver selected distance.
NOTE:
.The stop lights of the vehicle come
on when braking is performed by
the ICC system.
. When the brake is applied by the
system, a noise may be heard. This is
not a malfunction. When the ICC system detects a vehicle
ahead, the vehicle ahead detection indi-
cator and the speed control status in-
dicator (distance control mode)
illuminates in green.
*: The design of the set display may differ
depending on the model.
Vehicle ahead stops:
When a vehicle ahead is detected and it
gradually decelerates to stop, your vehi-
cle decelerates to a standstill. When your
vehicle is at a standstill, the “(RES+) Follow
Vehicle Ahead” message is displayed on
the vehicle information display.
Vehicle ahead accelerates:. When your vehicle is stopped for less
than approximately 3 seconds and the
vehicle ahead begins to move, your
vehicle will start moving again auto-
matically.
. When your vehicle is at a standstill for
more than approximately 3 seconds
and the vehicle ahead begins to
accelerate, push up the RES+ switch
or lightly depress the accelerator ped-
al. The ICC system starts to follow the
vehicle ahead.
. Always check surroundings before
restarting the vehicle. .
For vehicles equipped with ProPILOT
Assist with Navi-link and only when on
a limited access freeway (as identified
in the navigation map data):
— The time the vehicle can remain
stopped and automatically restart
is extended from 3 seconds to 30
seconds.
— If a vehicle ahead cuts in or out of the lane ahead, the vehicle may not
automatically start when the traffic
ahead begins to move. You need to
push up the RES+ switch or lightly
depress the accelerator pedal to
follow the vehicle directly ahead
when it is safe to do so.
Vehicle ahead not detected:
When a vehicle is no longer detected
ahead, the ICC system gradually acceler-
ates your vehicle to resume the pre-
viously vehicle set speed. The ICC
system then maintains the vehicle set
speed.
When a vehicle is no longer detected, the
vehicle ahead detection indicator and
speed control status indicator (maintain
speed control mode) turn off.
The ICC system gradually accelerates to
the vehicle set speed, but you can de-
press the accelerator pedal to quickly
accelerate. When a vehicle is no longer
detected and your vehicle is traveling
under approximately 15 MPH (25 km/h),
the ICC system automatically cancels. For
ProPILOT Assist with Navi-link equipped
vehicles on a limited access freeway as
identified in the navigation map data, the
ICC system cancels and a warning chime
sounds if your vehicle is at a standstill for
more than approximately 3 seconds and
a vehicle is not detected ahead.

When passing another vehicle, the vehicle
set speed indicatorflashes when the
vehicle speed exceeds the set speed. The
vehicle ahead detection indicator turns
off when the area ahead of the vehicle is
open. When the pedal is released, the
vehicle returns 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
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 Speed Limit Assist may not
operate properly and the actual
speed limit may not be applied to
the vehicle set speed in all condi-
tions. The driver must manually
control the vehicle speed.
Below are some examples:
— When the Traffic Sign Recog-
nition (TSR) system is not
functioning properly or turned
off. (See “Traffic Sign Recogni-
tion (TSR)” (P.5-43).)
— When driving in countries or areas not covered by the na-
vigation system.
— When crossing national boundaries.
— When driving on the exit of the limited access freeway as
identified in the navigation
map data.
— When driving in an area with nearby parallel roads (for ex-
ample, freeway with a parallel
service drive).
— When driving in an area where each lane has a different
speed limit sign. — When driving on a road under
construction or in a construc-
tion zone.
— When the data from the navi- gation system is not up-to-
date or is unavailable.
When the ProPILOT Assist with Navi-link is
active and it detects a change of the
speed limit, the new speed limit is indi-
cated and it can be applied to the vehicle
set speed automatically or manually.
The Speed Limit Assist operates:
. When the detected speed limit is 20
MPH (30 km/h) and above.
. The “Spd. Limit Assist” is enabled in the
settings menu of the vehicle informa-
tion display.
NOTE:
. While the accelerator pedal is oper-
ated with AUTO mode selected, the
Speed Limit Assist will function
(automatically adjust the vehicle set
speed) only when the detected
speed limit is faster than the vehicle
set speed.
. In the following situations, the
Speed Limit Assist will not operate:
—When an increase in the posted
speed limit is detected, but the vehicle set speed is already faster
than the new speed limit.
— When a decrease in the posted
speed limit is detected, but the
vehicle set speed is already lower
than the new speed limit.

ICC system limitations
WARNING
Listed below are the system limita-
tions for the ICC system. Failure to
operate the vehicle in accordance
with these system limitations could
result in serious injury or death:
. The ICC system is primarily in-
tended for use on highways and
freeways. It is not advisable to
use the ICC system in city/urban
traffic. .
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.
