4. ProPILOT Assist switch
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
control mode: For cruising at a preset
speed
NOTE:Steering Assist is not available in the
conventional (fixed speed) cruise con-
trol mode.
• Vehicle-to-vehicle distance control
mode: The ICC system maintains a
selected 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 se-
lected by the driver between 20 to 90
mph (30 to 144 km/h). When the ve-
hicle ahead slows to a stop, your ve-
hicle gradually decelerates to a stand-
still. When the vehicle is stopped, the
ICC system maintains braking force to
keep your vehicle stopped.

INTELLIGENT CRUISE CONTROL
(ICC) (for vehicles with ProPILOT
Assist)
WARNING
Failure to follow the warnings and in-
structions for proper use of the ICC sys-
tem could result in serious injury or
death. •
The ICC system is only an aid to assist
the driver and is not a collision
warning or avoidance device. It is rec-
ommended for highway use only and
it is not intended for city driving. It is
the driver’s responsibility to stay
alert, drive safely, and be in control of
the vehicle at all times.
• There are limitations to the ICC sys-
tem capability. The ICC system does
not function in all driving, traffic,
weather, and road conditions. 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.
• Always observe posted speed limits
and do not set the speed over them.
• The ICC system does not react to sta-
tionary and slow-moving vehicles.
5-104Starting and driving

•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 situa-
tions. Do not use the ICC system ex-
cept in appropriate road and traffic
conditions.
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 system decel-
erates 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 condi-
tions allow vehicle speeds to remain fairly
constant or when vehicle speeds change
gradually. If a vehicle moves into the travel-
ing lane ahead or if a vehicle traveling
ahead rapidly decelerates, the distance be-
tween vehicles may become closer be-
cause 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 notif y the
driver to take necessary action.
The ICC system cancels and a warning
chime sounds if the speed is below ap-
proximately 15 mph (25 km/h) 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 set speed
range is between approximately 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, selected by the
driver, from the vehicle ahead. If the ve-
hicle ahead comes to a stop, the vehicle
decelerates to a standstill. Once your ve-
hicle stops, the ICC system keeps the ve-
hicle stopped.
• When your vehicle is stopped for less than 3 seconds and the vehicle ahead
begins to move, your vehicle will start
moving again automatically. • When your vehicle is at a standstill for
more than 3 seconds and the vehicle
ahead begins to accelerate, push the
RES+ switch or lightly depress the accel-
erator pedal. The ICC system starts to
follow the vehicle ahead.
• When the vehicle traveling ahead moves to a different traveling lane, the ICC sys-
tem 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.
Starting and driving5-105

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 (25 km/h), the ICC system
automatically cancels.

Acceleration when passing
When the ICC system is engaged above 44
mph and following a slower vehicle (below
ICC set speed), and the turn signal is acti-
vated to the lef t, the ICC system will auto-
matically start to accelerate the vehicle to
help initiate passing on the lef t and will
begin to reduce the distance to the vehicle
directly ahead. Only the lef t 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
ICC system set speed. If another vehicle is
detected ahead, then the vehicle will accel-
erate up to the following speed of that ve-
hicle. If the vehicle is not steered into the
lef t lane to pass, the acceleration will stop
af ter a short time and regain the set follow-
ing 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 lef t turn signal and will briefly ac-
celerate the vehicle even if a lane
change is not initiated. This can in-
clude non-passing situations such as
lef t side exits.
• Ensure that when passing another
vehicle, the adjacent lane is clear be-
fore initiating the pass. Sudden
changes in traffic may occur while
passing.
– Always manually steer or brake as
needed
– Never solely rely on the system
ICC system 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.
• When the ICC system automatically
brings the car to a stop, your vehicle
can automatically accelerate if the
vehicle is stopped for less than ap-
proximately 3 seconds. Be prepared
to stop your vehicle if necessary.
Starting and driving5-109

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the radar
sensor may detect vehicles in a different
lane, or may temporarily not detect a ve-
hicle traveling ahead. This may cause the
radar system to decelerate or accelerate
the vehicle.
The detection of vehicles may also be af-
fected by vehicle operation (steering ma-
neuver or traveling position in the lane, etc.)
or vehicle condition.If this occurs, the ICC system may warn you
by blinking the system indicator and sound-
ing the chime unexpectedly. You will have to
manually control the proper distance away
from the vehicle traveling ahead.
