2. Vehicle information display3. Steering-wheel-mounted control (right)
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

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.
System Temporarily Unavailable
The following are conditions in which the
ICC system may be temporarily unavail-
able. In these instances, the ICC system
may not cancel and may not be able to
maintain the selected following distance
from the vehicle ahead.Condition A
Under the following conditions, the ICC sys-
tem is automatically canceled. A chime will
sound and the system will not be able to be
set:
• Any door is open.
• The driver’s seat belt is not fastened.
• The vehicle ahead is not detected and
your vehicle is traveling below the speed
of 15 mph (25 km/h).
• Your vehicle has been stopped by the ICC system for approximately 3 minutes or
longer.
• The shif t lever is not in the D (Drive) posi- tion or B mode.
• The electronic parking brake is applied.
• The Vehicle Dynamic Control (VDC) sys- tem is turned off.
• The Automatic Emergency Braking with Pedestrian Detection applies harder
braking.
• VDC (including the traction control sys- tem) operates.
• A wheel slips.
• When distance measurement becomes impaired due to adhesion of dirt or ob-
struction to the sensor.

STEERING ASSIST
WARNING
Failure to follow the warnings and in-
structions for proper use of the Steer-
ing Assist could result in serious injury
or death.
• The Steering Assist is not a replace-
ment for proper driving procedures
and is not designed to correct care-
less, 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 re-
sponsibility 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 Steer-
ing Assist does not function in all
driving, traffic, weather, and road
conditions. Always drive safely, pay
attention to the operation of the ve-
hicle, and manually control your ve-
hicle appropriately. •
The Steering Assist is intended for
use on well-developed freeways or
highways with gentle (moderate)
curves. To avoid risk of an accident,
do not use this system on local or
non-highway roads.
• The Steering Assist only steers the
vehicle to maintain its position 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 ve-
hicle 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 attentively
when using the Steering Assist. Read
and understand the Owner’s Manual
thoroughly before using the Steering
Assist. 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 Steering Assist except in ap-
propriate road and traffic conditions.
Steering Assist operation
The Steering Assist controls the steering
system to help keep your vehicle near the
center of the lane when driving. The Steer-
ing Assist is combined with the Intelligent
Cruise Control (ICC) system. For additional
information, see “Intelligent Cruise Control
(ICC) (with ProPILOT Assist)” (P. 5-104).
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 (HI) speed operation (the steer-
ing assist function is disabled af ter the
wiper operates for approximately 10
seconds).
Starting and driving5-115

Hands on detection
When the Steering Assist is activated, it
monitors the driver’s steering wheel
operation.
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
O1
appears in the vehicle information display.
If the driver does not operate the steering
wheel af ter the warning has been dis-
played, an audible alert sounds and the
warning flashes in the vehicle information
display, followed by a quick brake applica-
tion to request the driver to take control of
the vehicle again.
If the driver still does not respond, the Pro-
PILOT Assist 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, accelerating,
or operating the ProPILOT Assist switch.
WARNING
Steering Assist is not a system for
hands-free driving. Always keep your
hands on the steering wheel and drive
your vehicle safely. Failure to do so
could cause a collision resulting in seri-
ous personal injury or death.

Starting and driving5-117

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 wheel and a
sequence of warnings may occur. When
the driver holds and operates the steer-
ing wheel again, the warnings turn off.
Steering Assist limitations
WARNING
• In the following situations, the cam-
era may not detect lane markers cor-
rectly or may detect lane markers in-
correctly and the Steering Assist may
