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.
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.
Starting and driving5-101
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
equipped)
WARNING
Listed below are the system limita-
tions for the Speed Limit Assist. Fail-
ure to operate the vehicle in
accordance with these system lim-
itations could result in serious injury
or death:
.It is the driver’s responsibility to
select the proper speed, follow all
traffic regulations and observe
other road users.
. 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.

STEERING ASSIST
WARNING
Failure to follow the warnings and
instructions for proper use of the
Steering Assist could result in ser-
ious injury or death.
.The Steering Assist is not a re-
placement for proper driving pro-
cedures and is not designed to
correct careless, inattentive or
absent-minded driving. The
Steering Assist will not always
steer the vehicle to keep it in the
lane. It is not designed to prevent
loss of control. It is the driver’s
responsibility to stay alert, drive
safely, keep the vehicle in the
traveling lane, and be in control
of the vehicle at all times.
. As there is a performance limit to
the Steering Assist’s capability,
never rely solely on the system.
The Steering Assist does not
function in all driving, traffic,
weather, and road conditions. Al-
ways drive safely, pay attention
to the operation of the vehicle,
and manually control your vehicle
appropriately. .
The Steering Assist is intended
for use on well-developed high-
ways with gentle (moderate)
curves. To avoid risk of an acci-
dent, do not use this system on
local or non-highway roads.
. The Steering Assist only steers
the vehicle to maintain its posi-
tion in the center of a lane. The
vehicle will not steer to avoid
objects in the road in front of
the vehicle or to avoid a vehicle
moving into your lane.
. It is the driver’s responsibility to
stay alert, drive safely, keep the
vehicle in the traveling lane, and
be in control of the vehicle at all
times. Never take your hands off
the steering wheel when driving.
Always keep your hands on the
steering wheel and drive your
vehicle safely.
. Always drive carefully and atten-
tively when using the Steering
Assist. Read and understand the
Owner’s Manual thoroughly be-
fore using the Steering Assist. To
avoid serious injury or death, do
not rely on the system to prevent
accidents or to control the vehi-
cle’s speed in emergency situa-
tions. Do not use the Steering Assist except in appropriate road
and traffic conditions.
Steering Assist operation
Steering Assist helps the driver keep the
vehicle near the center of the lane when
both right and left lane markers are
detected. Steering Assist only operates
when combined with the Intelligent
Cruise Control (ICC) system. For additional
information, see “Intelligent Cruise Con-
trol (ICC)” (P.5-97).
The Steering Assist can be activated
when the following conditions are met:
.
The ICC system is activated.
. Lane markers on both sides are clearly
detected.
. A vehicle ahead is detected (when the
vehicle is driven at speeds under 37
MPH (60 km/h)).
. The driver grips the steering wheel.
. The vehicle is driven at the center of
the lane.
. The turn signals are not operated.
. The windshield wiper is not operated
in the high speed position (the Steer-
ing Assist function is disabled after the
wiper operates for approximately 10
seconds in the high speed position).

When the Steering Assist is in operation,
the Steering Assist status indicator, the
Steering Assist indicator, and the lane
marker indicatorandon the vehicle

sounds twice.
Intelligent Lane Intervention (I-LI)
With the Steering Assist active, when a
curve or strong cross wind exceeds the
capabilities of the system and your vehi-
cle approaches either the left or the right
side of the traveling lane, the I-LI system
will flash the I-LI indicator on the vehicle
information display and provide steering
wheel vibration to alert the driver. The
warning chime will also sound (4 rapid
beeps). Then, the I-LI system automati-
cally 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 and the warnings
cannot be turned off. For more informa-
tion, see “Intelligent Lane Intervention (I-
LI)” (P.5-51).WAF0639X
Hands on detection
When the Steering Assist is activated, it
monitors the driver’s steering wheel op-
eration.
If the steering wheel is not operated or
the driver takes his/her hands off the
steering wheel for a period of time, the
warning
appears in the vehicle infor-
mation display and the hands OFF warn-
ing light
illuminates.
If the driver does not operate the steering
wheel after the warning has been dis-
played and the warning light illuminated,
an audible alert sounds and both the
warning and the warning light flash. If the
driver still does not operate the steering wheel, the system applies a momentary
brake application to request the driver to
take control of the vehicle again.
If the driver still does not respond, the
system turns on the hazard flasher and
slows the vehicle to a complete stop.
The driver can cancel the deceleration at
any time by steering, braking, accelerat-
ing, or operating the ProPILOT Assist
switch.
WARNING
Steering Assist is not a system for a
hands-free driving. Always keep your
hands on the steering wheel and
drive your vehicle safely. Failure to
do so could cause a collision result-
ing in serious personal injury or
death.
NOTE:
If the driver lightly touches (instead of
firmly grips) the steering wheel, the
steering torque sensor may not detect
the driver’s hand(s) on the steering
wheel and a sequence of warnings
may occur. When the driver holds and
operates the steering wheel again, the
warnings turn off.
