●The cruise control will automatically cancel if
the vehicle slows more than 7 MPH (12 km/h)
below the set speed.
● If you move the selector lever to N (Neutral)
position, the cruise control will be canceled.
To reset at a faster cruising speed, use one of
the following methods:
● Depress the accelerator pedal. When the
vehicle attains the desired speed, push and
release the SET/COAST switch.
● Push and hold the RESUME/ACCELERATE
switch. When the vehicle attains the speed
you desire, release the switch.
● Push, then quickly release the
RESUME/ACCELERATE switch. Each time you
do this, the set speed will increase by about
1 MPH (1.6 km/h). To reset at a slower cruising speed,
use one of
the following methods:
● Lightly tap the brake pedal. When the ve-
hicle attains the desired speed, push the
SET/COAST switch and release it.
● Push and hold the SET/COAST switch. Re-
lease the switch when the vehicle slows
down to the desired speed.
● Push, then quickly release the SET/COAST
switch. Each time you do this, the set speed
will decrease by about 1 MPH (1.6 km/h).
To resume the preset speed, push and release
the RESUME/ACCELERATE switch. The vehicle
will resume the last set cruising speed when the
vehicle speed is over 25 MPH (40 km/h). The Intelligent Cruise Control (ICC) system au-
tomatically maintains a selected distance from
the vehicle traveling in front of you according to
that vehicle’s speed (up to the set speed), or at
the set speed when the road ahead is clear.
The ICC function can be set to one of two cruise
control modes:
●
Vehicle-to-vehicle distance control mode:
For maintaining a selected distance between
your vehicle and the vehicle in front of you
up to the preset speed.
● Conventional (fixed speed) cruise control
mode:
For cruising at a preset speed.
WARNING
● Always drive carefully and attentively when
using either cruise control mode. Read and
understand the Owner’s Manual thoroughly
before using the ICC system. To avoid seri-
ous injury or death, do not rely on the system
to prevent accidents or to control the vehi-
cle’s speed in emergency situations. Do not
use the ICC system except in appropriate
road and traffic conditions.

A.
VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE
In the vehicle-to-vehicle distance control mode,
the Intelligent Cruise Control (ICC) system auto-
matically maintains a selected distance from
the vehicle traveling in front of you according to
that vehicle’s speed (up to the set speed), or at
the set speed when the road ahead is clear.
With ICC, the driver can maintain the same
speed as other vehicles without the constant
need to adjust the set speed as you would with
a normal cruise control system.
PRECAUTIONS ON VEHICLE-TO-
VEHICLE DISTANCE CONTROL MODE
The system is intended to enhance the opera-
tion of the vehicle when following a vehicle
traveling in the same lane and direction.
If the distance sensor
Adetects a slower
moving vehicle ahead, the system will reduce
the vehicle speed so that your vehicle follows
the vehicle in front at the selected distance.
The system automatically controls the throttle
and applies the brakes (up to 25% of vehicle
braking power) if necessary.
The detection range of the sensor is approxi-
mately 390 ft (120 m) ahead.
WARNING
● This system is only an aid to assist the driver
and is not a collision warning or avoidance
device. It is the driver’s responsibility to stay
alert, drive safely and be in control of the
vehicle at all times.
● The system is primarily intended for use on
straight, dry, open roads with light traffic. It
is not advisable to use the system in city
traffic or congested areas.
● This system will not adapt automatically to
road conditions. This system should be used
in evenly flowing traffic. Do not use the sys-
tem on roads with sharp curves, or on icy
roads, in heavy rain or in fog.
The distance sensor will not detect the follow-
ing objects:
● Stationary and slow moving vehicles
● Pedestrians or objects in the roadway
● Oncoming vehicles in the same lane
● Motorcycles traveling offset in the travel
lane

WARNING
●As there is a performance limit to the dis-
tance control function, never rely solely on
the Intelligent Cruise Control (ICC) system.
This system does not correct careless, inat-
tentive or absent-minded driving, or over-
come poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed by de-
pressing the brake pedal, depending on the
distance to the vehicle ahead and the sur-
rounding circumstances in order to maintain
a safe distance between vehicles.
● If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within the
limitations of the system. The system will
cancel once it judges that the vehicle has
come to a standstill and sound a warning
chime. To prevent the vehicle from moving,
the driver must depress the brake pedal.
● The system may not function properly under
the following conditions. To avoid accidents,
never use the ICC system under the following
conditions:
– On roads where the traffic is heavy or there are sharp curves
– On slippery road surfaces such as on ice or snow, etc. – On off-road surfaces such as on sand or
rock, etc.
– During bad weather (rain, fog, snow, etc.)
– When the windshield wipers are operat- ing at high speed. The system may cancel
when the wipers are set to the AUTO
position.
– When strong light (for example, at sun- rise or sunset) is directly shining on the
front of the vehicle
– When rain, snow or dirt adhere to the sys- tem sensor
– On steep downhill roads (the vehicle may go beyond the set vehicle speed and fre-
quent braking may result in overheating
the brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it difficult to keep a proper distance between vehicles
because of frequent acceleration or
deceleration
– When towing a trailer or other vehicle ●
In some road or traffic conditions, a vehicle
or object can unexpectedly come into the
sensor detection zone and cause automatic
braking. You may need to control the dis-
tance from other vehicles using the accelera-
tor pedal. Always stay alert and avoid using
the ICC system when it is not recommended
in this section.

System operation
WARNING
Normally when controlling the distance to a
vehicle ahead, this system automatically accel-
erates or decelerates your vehicle according to
the speed of the vehicle ahead. Depress the
accelerator to properly accelerate your vehicle
when acceleration is required for a lanechange. Depress the brake pedal when decel-
eration is required to maintain a safe distance
to the vehicle ahead due to its sudden braking
or if a vehicle cuts in. Always stay alert when
using the Intelligent Cruise Control (ICC)
system.
The driver sets the desired vehicle speed based
on the road conditions. The ICC system main-
tains 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 con-
trolling the throttle and applying the brakes to
match the speed of a slower vehicle ahead. The
system then controls the vehicle speed based
on the speed of the vehicle ahead to maintain
the driver selected distance.
The stoplights of the vehicle come on when brak-
ing is performed by the ICC system.
When the brake operates, a noise may be heard
or felt. This is not a malfunction.
When a vehicle ahead is detected, the vehicle
ahead detection indicator comes on. The ICC
system will also display the set speed and
selected distance.
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.
If a vehicle ahead appears during acceleration
to the set vehicle speed or any time the ICC
system is in operation, the system controls the
distance to that vehicle.

To reset at a slower cruising speed,use one of
the following methods:
● Lightly tap the brake pedal. When the ve-
hicle attains the desired speed, push the
SET/COAST switch and release it.
● Push and hold the SET/COAST switch. The
set vehicle speed will decrease by approxi-
mately 5 MPH or 5 km/h.
● Push, then quickly release the SET/COAST
switch. Each time you do this, the set speed
will decrease by approximately 1 MPH or 1
km/h.
To resume the preset speed, push and release
the RESUME/ACCELERATE switch. The vehicle
will resume the last set cruising speed when the
vehicle speed is over 20 MPH (32 km/h).
How to change set distance to
vehicle ahead
The distance to the vehicle ahead can be se-
lected at any time depending on the traffic
conditions.
Each time the DISTANCE switch
Ais pushed,
the set distance will change to long, middle,
short and back to long again in that sequence.

NOTE:
The approach warning chime may sound and the
system display may blink when the ICC sensor
detects some reflectors
Awhich are fitted on
vehicles in other lanes or on the side of the road.
This may cause the ICC system to decelerate or
accelerate the vehicle. The ICC sensor may de-
tect these reflectors when the vehicle is driven
on winding roads, hilly roads or when entering
or exiting a curve. The ICC sensor may also de-
tect reflectors on narrow roads or in road con-
struction zones. In these cases you will have to
manually control the proper distance ahead of
your vehicle. Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driving
position in the lane) or traffic or vehicle condi-
tion (for example, if a vehicle is being driven
with some damage).
Automatic cancellation
A chime sounds under the following conditions
and the control is automatically canceled.
●
When the vehicle speed falls below approxi-
mately 15 MPH (24 km/h)
● When the system judges the vehicle is at a
standstill
● When the selector lever is shifted to the N
(Neutral) position
● When the windshield wipers are operating at
high speed. The system may cancel when
the wipers are set to the AUTO position.
● When the VDC is turned off
● When the ABS or VDC operates
● When the parking brake is applied
● When the SNOW mode switch is pushed on.
● When the 4WD shift switch is in the 4H or 4L
position (for 4WD models) ●
When driving into a strong light (i.e., sun-
light)
● When distance measurement becomes im-
paired due to adhesion of dirt or obstruction
to the sensor
● When a wheel slips
