VEHICLE-TO-VEHICLE
DISTANCE CONTROL MODE
OPERATION
The vehicle-to-vehicle distance control mode
is designed to maintain a selected distance
from the vehicle in front of you and can re-
duce the speed to match a slower vehicle
ahead. The system will decelerate the vehicle
as necessary and if the vehicle ahead comes
to a stop, the vehicle decelerates to a stand-
still. 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 vehicle speeds
change gradually. If a vehicle moves into the
traveling lane ahead or if a vehicle traveling
ahead rapidly decelerates, the distance be-
tween vehicles may become closer because
the ICC system cannot decelerate the vehicle
quickly enough. If this occurs, the ICC system
will sound a warning chime and blink the
system display to notify the driver to take
necessary action.The system will cancel and a warning chime
will sound if the speed is below approxi-
mately 15 mph (24 km/h) and a vehicle is not
detected ahead. The system will also disen-
gage when the vehicle goes above the maxi-
mum set speed.
For additional information, refer to “Ap-
proach warning” in this section.
The following items are controlled in the
vehicle-to-vehicle distance control mode:
∙ When there are no vehicles traveling ahead, the vehicle-to-vehicle distance
control mode maintains the speed set by
the driver. The set speed range is be-
tween approximately 20 and 90 mph (32
and 144 km/h).
∙ When there is a vehicle traveling ahead, the vehicle-to-vehicle distance control
mode 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 within the limitations of the sys-
tem. The system will cancel once it judges
a standstill with a warning chime. ∙ When the vehicle traveling ahead has
moved out from its lane of travel, the
vehicle-to-vehicle distance control mode
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 con-
gestion.
5-88Starting and driving

When the SET– switch is pushed under the
following conditions, the system cannot be
set.
A warning chime will sound and a message
will pop up:∙ When the VDC system is off (To use the ICC system, turn on the VDC system.
Push the ICC switch to turn off the ICC
system and reset the ICC switch by push-
ing the ICC switch again.)
For additional information about the
VDC system, refer to “Vehicle Dynamic
Control (VDC) system” in this section.
∙ When VDC is operating
∙ When a wheel is slipping (To use the ICC system, make sure the wheels are no lon-
ger slipping.)
1System set display with vehicle ahead
2System set display without vehicle 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 system then controls the vehicle
speed based on the speed of the vehicle
ahead to maintain the driver selected dis-
tance.
NOTE:
∙ The stop lights of the vehicle come on
when braking is performed by the ICC
system.
∙ When the brake operates, a noise may be
heard. 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 accelera-
tion to the set vehicle speed or any time the
ICC system is in operation, the system con-
trols the distance to that vehicle.
LSD2719
5-92Starting and driving

To reset at a slower cruising speed,use one
of the following methods:
∙ Lightly tap the brake pedal. When the vehicle attains the desired speed, push
the SET– switch and release it.
∙ Push and hold the SET– switch. The set vehicle speed will decrease by approxi-
mately 5 mph (5 km/h).
∙ Push, then quickly release the SET– switch. Each time you do this, the set
speed will decrease by approximately
1 mph (1 km/h).
To resume the preset speed, push and re-
lease the RES+ switch. The vehicle will re-
sume the last set cruising speed when the
vehicle speed is over 20 mph (32 km/h).
How to change the set distance to
the vehicle ahead
The distance to the vehicle ahead can be
selected at any time depending on the traffic
conditions.
Each time the distance
switchAis
pushed, the set distance will change to long,
middle, short and back to long again, in that
sequence.
Distance Approximate distance at
60 mph (100 km/h) [ft (m)]
1. Long 200 (60)
2. Middle 150 (45)
3. Short 100 (30)
∙ The distance to the vehicle ahead will change according to the vehicle speed.
The higher the vehicle speed, the longer
the distance.
∙ If the engine is stopped, the set distance becomes “long.” (Each time the engine is
started, the initial setting becomes
“long.”)

VEHICLE-TO-VEHICLE
DISTANCE CONTROL MODE
LIMITATIONS
WARNING
Listed below are the system limitations for
the ICC system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious injury or
death.
∙ The ICC system is primarily intended foruse 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 automati- cally 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 dis-
tance control function, never rely solely
on the ICC system. This system does not
correct careless, inattentive or absent-
minded driving, or overcome poor visibil-
ity in rain, fog, or other bad weather. De-
celerate the vehicle speed by depressing
the brake pedal, depending on the dis-
tance to the vehicle ahead and the sur-
rounding circumstances in order to main-
tain 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.
∙ Always pay attention to the operation of the vehicle and be ready to manually con-
trol the proper following distance. The
ICC system may not be able to maintain
the selected distance between vehicles
(following distance) or selected vehicle
speed under some circumstances. ∙ The system may not detect the vehicle in
front of you in certain road or weather
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.
– During bad weather (rain, fog, snow, etc.)
– When rain, snow or dirt adhere to the bumper around the distance sensor
– On steep downhill roads (the vehicle may go beyond the set vehicle speed
and frequent braking may result in
overheating the brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it diffi- cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
– Interference by other radar sources
∙ Do not use the ICC system if you are tow- ing a trailer. The system may not detect a
vehicle ahead.
