When driving on the highway at a vehicle
set speed and approaching a slower
traveling vehicle ahead, the ICC system
adjusts the speed to maintain the dis-
tance, selected by the driver, from the
vehicle ahead. If the vehicle ahead
changes lanes or exits the highway, the
ICC system accelerates and maintains the
vehicle set speed. Pay attention to the
driving operation to maintain control of
the vehicle as it accelerates to the set
speed.
The vehicle may not maintain the set
speed on winding or hilly roads. If this
occurs, you will have to manually control
the vehicle speed.Normally when controlling the distance to
a vehicle ahead, the system automatically
accelerates or decelerates your vehicle
according to the speed of the vehicle
ahead.
Depress the accelerator to properly ac-
celerate your vehicle when acceleration is
required for a lane change. Depress the
brake pedal when deceleration is required
to maintain a safe distance to the vehicle
ahead due to sudden braking or if a
vehicle cuts in. Always stay alert when
using the ICC system.
WAF0579XSystem set display — no vehicle detected ahead*
No vehicle detected ahead:
The driver sets the desired vehicle speed
based on the road conditions. The ICC
system maintains the vehicle set speed,
similar to standard cruise control, as long
as no vehicle is detected in the lane
ahead. The ICC system displays the vehi-
cle set speed.
*: The design of the set display may differ
depending on the model.

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
Page 355 of 556

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.
WAF0581X
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.

5-102Starting and driving
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 the vehicle set speed), and
the turn signal is activated to the left, the
ICC system will automatically start to
accelerate 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 vehicle 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.
WARNING
In order to reduce the risk of a
collision that may result in serious
injury or death, please be aware of
the following: .
This function is only activated
with the left turn signal and will
briefly accelerate the vehicle even
if a lane change is not initiated.
This can include non-passing si-
tuations such as left side exits.
. Ensure that when passing an-
other vehicle, the adjacent lane
is clear before initiating the pass.
Sudden changes in traffic may
occur while passing. Always
manually steer or brake as
needed. Never solely rely on the
system.
Speed Limit Assist - a feature of
ProPILOT Assist with Navi-link (if so

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.
. For vehicles equipped with ProPI-
LOT Assist with Navi-link and only
