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 reduce the speed to match a
slower vehicle ahead. The system will de-
celerate 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
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 ve-
hicle quickly enough. If this occurs, the ICC
system will sound a warning chime and blink
the system display to notif y the driver to take
necessary action.
The system will cancel and a warning
chime will sound if the speed is below ap-
proximately 15 mph (24 km/h) and a vehicle
is not detected ahead. The system will alsodisengage when the vehicle goes above
the maximum 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
between 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 de-
celerates to a standstill within the limi-
tations of the system. 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 ve-
hicle 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 driving5-71

When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC system will adjust 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 will accelerate and main-
tain the speed up to the set speed. Pay
attention to the driving operation to main-
tain 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 oc-
curs, you will have to manually control the
vehicle speed.Normally when controlling the distance to
a vehicle ahead, this system automatically
accelerates or decelerates your vehicle ac-
cording to the speed of the vehicle ahead.
Depress the accelerator to properly accel-
erate your vehicle when acceleration is re-
quired for a lane change. Depress the brake
pedal when deceleration 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 us-
ing the ICC system.VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE SWITCHES
The system is operated by the ICC switch
and four control switches, all mounted on
the steering wheel.
1. CANCEL switch:
Deactivates the system without eras-
ing the set speed.
2. RES+ switch:

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, simi-
lar 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 ve-
hicle by controlling the throttle and apply-
ing 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.
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 ve-
hicle 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 acceler-
ates your vehicle to resume the previously
set vehicle speed. The ICC system then
maintains the set speed.
LSD3496
Starting and driving5-75

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.
When a vehicle is no longer detected under
approximately 15 mph (24 km/h), the sys-
tem will be canceled.When passing another vehicle,the set
speed indicator
Awill flash when the
vehicle speed exceeds the set speed. The
vehicle detect indicator will turn off when
the area ahead of the vehicle is open. When
the pedal is released, the vehicle will return
to the previously set speed.
Even though your vehicle speed is set in the
ICC system, you can depress the accelera-
tor pedal when it is necessary to accelerate
your vehicle rapidly.
How to change the set vehicle
speed
To cancel the preset speed, use one of the
following methods:
∙ Push the CANCEL switch. The set ve- hicle speed indicator will go out.
∙ Tap the brake pedal. The set vehicle speed indicator will go out.
∙ Turn the ICC switch off. The ICC indica- tors will go out.
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– switch.
∙ Push and hold the RES+ switch. The set vehicle speed will increase by approxi-
mately 5 mph (5 km/h).
∙ Push, then quickly release the RES+ switch. Each time you do this, the set
speed will increase by approximately
1 mph (1 km/h).

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
release the RES+ switch. The vehicle will
resume 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 traf-
fic conditions.
Each time the distance
switchAis
pushed, the set distance will change to
long, middle, short and back to long again,
in that sequence.

60 mph (100 km/h) [f t (m)]
1. Long 200 (60)
2. Middle 150 (45)
3. Short 90 (30)
∙ The distance to the vehicle ahead will change according to the vehicle speed.
The higher the vehicle speed, the longer
the distance.
∙ The distance setting will remain at the current setting even if the engine is re-
started.

Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that
vehicle or if another vehicle cuts in, the sys-
tem warns the driver with the chime and
ICC system display. Decelerate by depress-
ing the brake pedal to maintain a safe ve-
hicle distance if:∙ The chime sounds.
∙ The vehicle ahead detection indicator blinks.
The warning chime may not sound in
some cases when there is a short distance
between vehicles. Some examples are: ∙ When the vehicles are traveling at the same speed and the distance between
vehicles is not changing.
∙ When the vehicle ahead is traveling faster and the distance between ve-
hicles is increasing.
∙ When a vehicle cuts in near your vehicle. The warning chime will not sound when:
∙ The vehicle approaches other vehicles that are parked or moving slowly.
∙ The accelerator pedal is depressed, overriding the system.
NOTE:
The approach warning chime may sound
and the system display may blink when
the ICC sensor detects objects on the
side of the vehicle or on the side of the
road. This may cause the ICC system to
decelerate or accelerate the vehicle. The
ICC sensor may detect these objects
when the vehicle is driven on winding
roads, narrow roads, hilly roads, or when
entering or exiting a curve. In these
cases you will have to manually control
the proper distance ahead of your ve-
hicle.
Also, the sensor sensitivity can be affected
by vehicle operation (steering maneuver or
driving position in the lane) or traffic or ve-
hicle condition (for example, if a vehicle is
being driven with some damage).
Automatic cancellation
A chime sounds under the following condi-
tions and the control is automatically can-
celed: ∙ When the vehicle ahead is not detected and your vehicle is traveling below the
speed of 15 mph (24 km/h)
∙ When the system judges the vehicle is at a standstill
∙ When the shif t lever is not in the D (Drive) position, Manual mode or L (Low) range.
∙ When the parking brake system is ap- plied
∙ When the VDC system is turned off
∙ When VDC operates
∙
When distance measurement becomes
impaired due to adhesion of dirt or ob-
struction to the sensor
∙ When a wheel slips
∙ When the radar signal is temporarily in- terrupted
