VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE FUNCTION

In the vehicle-to-vehicle distance control mode, the Intelligent Cruise Control (ICC) system automatically main-
tains a selected distance from the vehicle traveling in front of own vehicle according to that vehicle's speed (up
to the set speed), or at the set speed when the road ahead is clear.
With ICC system, the driver can maintain the same speed as other vehicles without the constant need to
adjust the set speed as driver would with a normal cruise control system.
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 32 and 144 km/h (20 and 90 MPH).

• When there is a vehicle traveling ahead, the vehicle-to-vehicle distance control mode adjusts the speed to

maintain the distance, selected by driver, from a vehicle ahead. The adjusting speed range is up to the set
speed.
If the vehicle ahead come 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 con-

trol mode accelerates and maintains vehicle speed up to the set speed.

CAUTION:

If the vehicle ahead comes to 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.
NOTE:
• When the accelerator pedal is depressed, the brake operation and the warning are not performed by the ICC

system.

• When the DCA system is ON and when the accelerator pedal is depressed, the DCA system is operated.

Refer to

CCS-192, "System Description"

OPERATION DESCRIPTION

Quickly push (less than 1.5 seconds) and release the MAIN switch ON.
The MAIN switch indicator, set distance indicator, own vehicle indicator, and set vehicle speed indicator come
on and ICC system is set to a standby state.
ICC sensor integrated unit performs the control as per the following:

Set Condition

Under a standby state, pushing down the SET/COAST switch will start system control.
• When vehicle speed is between approximately 32 km/h and 144 km/h (20 MPH and 90 MPH).
• When vehicle speed is below approximately 32 km/h (20 MPH) if the vehicle ahead is detected. The set

vehicle speed becomes 32 km/h (20 MPH).

If the system is canceled by conditions 1-6 below, the system will resume control at the last set cruising speed
by pushing up the RESUME/ACCELERATE switch.
NOTE:

Constant
speed

Comparing the set vehicle speed with the current vehicle speed, transmit the command to ECM via CAN communication
to reach the set vehicle speed, and controls the electric throttle control actuator.

Decelera-
tion

When a vehicle ahead (slower than driver set vehicle speed) appears or when a vehicle ahead slows down, the system
controls the electric throttle control actuator into the close direction and decelerates the vehicle. If greater deceleration
is necessary, the system transmits the brake fluid pressure command signal to the brake booster control unit via ITS com-
munication and operates the brake.

Following

The system controls the electric throttle control actuator and the brake fluid pressure to keep the proper distance between
the vehicles according to the vehicle speed change of the vehicle ahead.

Accelera-
tion

When a vehicle ahead is not detected because of it changes lanes or own vehicle changes lanes during the following
driving, the system controls the electric throttle control actuator in the open direction and accelerates the vehicle to the
set vehicle speed slowly.

[ICC (FULL SPEED RANGE)]

• When the SET/COAST switch is pushed under the following condi-

tions, the system cannot be set and the set vehicle speed indicator
will blink for approximately 2 seconds.

- When traveling below 32 km/h (20 MPH) and the vehicle ahead is

not detected.

- When the selector lever is not in the “D”, “DS” position or manual

mode.

- When the front wipers are operating at LO or HI.

(If the vehicle is equipped with a rain sensing auto-wiper, the sys-
tem may cancel when the wipers are set to INT)

- When the parking brakes are applied.
- When the brakes are operated by the driver.
• When the SET/COAST switch is pushed under the following condi-

tions, the system cannot be set. A warning chime will sound and
the set speed indicator and own vehicle indicator will blink.

- When the snow mode switch is ON. (To use the ICC system, turn

OFF the snow mode switch, push the MAIN switch to turn OFF the
ICC system and reset the ICC system by pushing the MAIN switch
again.)

- When the VDC is OFF. (To use the ICC system, turn ON the VDC

system, push the MAIN switch to turn OFF the ICC system and
reset the ICC system by pushing the MAIN switch again.)

- When ABS or VDC (including the TCS) operates.
- When driving into a strong light (i.e., sunlight).
- When the wheel is slipping. (To use the ICC system, make sure the wheels are no longer spinning, push the

MAIN switch to turn OFF the ICC system and reset the ICC system by pushing the MAIN switch again.)

Cancel Conditions

When CANCEL switch is pressed.

When brake pedal is depressed.

When the vehicle ahead is not detected below the speed of 24 km/h (15 MPH).

When the selector lever is not in the “D”, “DS” position or manual mode.

When the parking brakes are applied.

When the system judges the vehicle is at standstill.

When the front wipers are operating at LO or HI.
(If the vehicle is equipped with a rain sensing auto-wiper, the system may cancel when the wipers are set
to INT)

When the snow mode switch is turned ON.

When ABS or VDC (including the TCS) operates.

10. When the MAIN switch is turned OFF.
11. When a wheel slips.
12. When driving into a strong light (i.e., sunlight).
13. When the VDC is turned OFF.
