PROPILOT ASSIST SYSTEM
OPERATION1Steering-wheel-mounted control (left)
2Vehicle information display
3Steering-wheel-mounted control (right)
4ProPILOT 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 conven-
tional (fixed speed) cruise control mode.
•Vehicle-to-vehicle distance control mode:
The ICC system maintains a selected dis-
tance 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 selected by the driver between 20 to
90 mph (30 to 144 km/h). When the ve-
hicle ahead slows to a stop, your vehicle
gradually decelerates to a standstill. When
the vehicle is stopped, the ICC system
maintains braking force to keep your ve-
hicle stopped.
NOTE:When your vehicle is stopped for less than 3
seconds and the vehicle ahead begins to
move, your vehicle will start moving again
automatically.

button on the steering wheel to call up the
“Driving Aids” setting display in the upper
display.
• When enabling/disabling the system through the lower display, the system re-
tains the current settings even if the en-
gine is restarted.
How to cancel the ProPILOT Assist
system
To cancel the ProPILOT Assist system, use
one of the following methods:
• Push the CANCEL switch.
• Tap the brake pedal (except at a standstill).
• Push the ProPILOT Assist switch to turnthe system off. The ProPILOT Assist status
indicator will go out.
When the ProPILOT Assist system is can-
celed while the vehicle is stopped, the elec-
tronic parking brake is automatically
activated.
WARNING
To prevent the vehicle from moving or roll-
ing unexpectedly, which could result in se-
rious personal injury or property damage,
before exiting the vehicle make sure to
push the ProPILOT Assist switch to turn
the system off, place the shift lever in the P
(Park) position, and turn the engine off.
INTELLIGENT CRUISE CONTROL
(ICC) (for vehicles with ProPILOT
Assist)
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the ICC system
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 recommended for
highway use only and it is not intended
for city driving. It is the driver’s respon-
sibility to stay alert, drive safely, and be
in control of the vehicle at all times. •
There are limitations to the ICC system
capability. The ICC system does not
function in all driving, traffic, weather,
and road conditions. 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.
• 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.
• Always drive carefully and attentively
when using the ICC system. Read and
understand the Owner’s Manual thor-
oughly 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
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 decelerates
the vehicle as necessary and if the vehicle
Starting and driving5-87

ahead comes to a stop, the vehicle deceler-
ates 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 ve-
hicle speeds change gradually. If a vehicle
moves into the traveling lane ahead or if a
vehicle traveling ahead rapidly decelerates,
the distance between vehicles may become
closer because the ICC system cannot decel-
erate the vehicle quickly enough. If this oc-
curs, 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 de-
tected 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 vehicle ahead
comes to a stop, the vehicle decelerates to
a standstill. Once your vehicle stops, the
ICC system keeps the vehicle 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 be-
gins to accelerate, push the RES+ switch or
lightly depress the accelerator pedal. The
ICC system starts to follow the vehicle
ahead.
• When the vehicle traveling ahead moves to a different traveling lane, the ICC system
accelerates and maintains vehicle speed up
to the set speed.
The ICC system does not control vehicle
speed or warn you when you approach sta-
tionary and slow moving vehicles. You must
pay attention to vehicle operation to main-
tain proper distance from vehicles ahead
when approaching toll gates or traffic
congestion. When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC system adjusts the speed to
maintain the distance, selected by the driver,
from the vehicle ahead. If the vehicle ahead
changes lanes or exits the freeway, the ICC
system accelerates and maintains the speed
up to the 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.
SSD0254
5-88Starting and driving

Normally when controlling the distance to a
vehicle ahead, the system automatically ac-
celerates or decelerates your vehicle accord-
ing to the speed of the vehicle ahead.
Depress the accelerator to properly acceler-
ate 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.
No vehicle detected ahead
The driver sets the desired vehicle speed
based on the road conditions. The ICC sys-
tem maintains the set vehicle speed, similar to
standard cruise control, as long as no vehicle
is detected in the lane ahead. The ICC system
displays the set speed.
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 controls the ve-
hicle 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 system, anoise may be heard. This is not a
malfunction.
When the ICC system detects a vehicle
ahead, the vehicle ahead detection indicator
and the speed control status indicator (dis-
tance control mode) illuminates (solid green
).
Vehicle ahead stops
When the vehicle ahead decelerates to stop,
your vehicle decelerates to a standstill within
the system capability. Once your vehicle
stops, the ICC system automatically applies
the brakes to keep the vehicle stopped. When
your vehicle 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 sec-
onds, your vehicle will automatically follow
the vehicle as it accelerates from a stop.
Vehicle ahead accelerates
When your vehicle is stopped and the vehicle
ahead begins to accelerate, push the RES+
switch or lightly depress the accelerator
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 accelerates 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 speed control status indicator (maintain
speed control mode) illuminates (green out-
line
).
The ICC system gradually accelerates to the
set speed, but you can depress the accelera-
tor pedal to quickly accelerate. When a ve-
hicle is no longer detected and your vehicle is
traveling under approximately 15 mph (25
km/h), the ICC system automatically cancels. When passing another vehicle, the set speed
indicator
OBflashes 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 previ-
ously set speed. Even though your vehicle
speed is set in the ICC system, you can de-
press the accelerator pedal when it is neces-
sary to accelerate your vehicle rapidly.
