VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
Set Checking
1. Press the ON/OFF switch for less than 1.5 seconds.
2. Drive the vehicle between 25 MPH (40 km/h for CANADA models) and 90 MPH (144 km/h for CANADA
models).
3. Push the COAST/SET switch.
4. Confirm that the desired speed is set as hand is released from the COAST/SET switch.
NOTE:

When there is no vehicle ahead, drive at the set speed steadily.

When there is a vehicle ahead, control to maintain distance from the vehicle ahead, watching its speed.

The set vehicle speed is displayed on the ICC system indicator in the combination meters.
Check For Increase Of The Cruising Speed
1. Set vehicle-to-vehicle distance control mode at desired speed.
2. Check if the set speed increases by 1 MPH (1 km/h for CANADA models) as ACCEL/RES switch is
pushed.
NOTE:
The maximum set speed of the vehicle-to-vehicle distance control mode is 90 MPH (144 km/h for CANADA
models).
Check For Decrease Of The Cruising Speed
1. Set vehicle-to-vehicle distance control mode at desired speed.
2. Check if the set speed decreases by 1 MPH (1 km/h for CANADA models) as COAST/SET switch is
pushed.
NOTE:

Vehicle-to-vehicle distance control mode is automatically turned off when the driving speed lowers to 20
MPH (32 km/h for CANADA models) due to the deceleration of the vehicle ahead.

The minimum set speed of the vehicle-to-vehicle distance control mode is 25 MPH (40 km/h for CANADA
models).
Check For The Cancellation Of Vehicle-To-Vehicle Distance Control Mode (Normal Driving
Condition) In The Following Cases:
1. When the brake pedal is depressed after the system is turned on.
2. When the select lever is shifted into other than “D” including manual shift.
3. When the ON/OFF switch is turned off.
4. When CANCEL switch is operated.
Check For Restoring The Speed That Is Set By Vehicle-To-Vehicle Distance Control Mode
Before Cancellation
1. Cancel the system by depressing the foot brake.Then, check that the speed before cancellation is
restored when pressing ACCEL/RES switch with 25 MPH (40 km/h for CANADA models) or above.
2. Cancel the system by shifting the select lever into other than “D”, Then, check if the speed set before the
cancellation is restored when ACCEL/RES switch is pressed.
3. Check if the speed previously set is restored when ACCEL/RES switch is operated with driving 25 MPH
(40 km/h for CANADA models), after canceling vehicle-to-vehicle distance control mode by operating the
CANCEL switch.

Check For ON/OFF Switch
1. Start the engine.Then, check the following operations are car-
ried correctly.
2. Vehicle-to-vehicle distance control mode is displayed in speed-
ometer illuminates when ON/OFF switch is pressed “ON” for
less than 1.5 seconds and ready for operation.The illumination
goes off when ON/OFF switch is turned to OFF.
3. “CRUISE” illumination and ICC system display go off when the
key switch is turned to OFF while ON/OFF switch is ON
(“CRUISE” illumination is ON and vehicle-to-vehicle distance
control mode is ready for operation).
Check For ACCEL/RES, COAST/SET, CANCEL Switches
1. Check if ACCEL/RES, COAST/SET, CANCEL switches are operated smoothly.
2. Check if buttons come up as hand is released from the buttons.
Check For Distance Switch
1. Start the engine.
2. Press the ON/OFF switch for less than 1.5 seconds.
3. Press the DISTANCE switch.
4. Check if the set distance indicator changes display in order of:
(long)→(middle)→(short).
NOTE:
The set distance indicator shows 'long' immediately after the engine starts.
CONVENTIONAL (FIXED SPEED) CRUISE CONTROL MODE
Set Checking
1. Press the ON/OFF switch for more than 1.5 seconds.
2. Drive the vehicle between 25 MPH (40 km/h for CANADA models) and 90 MPH (144 km/h for CANADA
models).
3. Push the COAST/SET switch.
4. Confirm that the desired speed is set as hand is released from the COAST/SET switch.
NOTE:

ICC system display in the combination meters shows nothing.

Check For Increase Of The Cruising Speed
1. Set the conventional (fixed speed) cruise control mode at desired speed.
2. Check if the set speed increases by 1 MPH (1.6 km/h for CANADA models) as ACCEL/RES switch is
pushed.
NOTE:

If the ACCEL/RES switch is kept lifting up during cruise control driving, the vehicle speed increases until
the switch is released.

The maximum set speed is 90 MPH (144 km/h for CANADA models).
Check For Decrease Of The Cruising Speed
1. Set the conventional (fixed speed) cruise control mode at desired speed.
2. Check if the set speed decreases by 1 MPH (1.6 km/h for CANADA models) as COAST/SET switch is
pushed.
NOTE:

Conventional (fixed speed) cruise control mode is automatically turned off when the driving speed lowers
to 20 MPH (32 km/h for CANADA models) due to the deceleration of the vehicle ahead.

The lowest set speed is 25 MPH (40 km/h for CANADA models).
Check For The Cancellation Of Conventional (Fixed Speed) Cruise Control Mode (Normal
Driving Condition) In The Following Cases:
Refer.toACS-9, "Check For The Cancellation Of Vehicle-To-Vehicle Distance Control Mode (Normal Driving
Condition) In The Following Cases:"
Check For Restoring The Speed That Is Set By Conventional (Fixed Speed) Cruise Control
Mode Before ICC Cancellation
Refer to.ACS-9, "Check For Restoring The Speed That Is Set By Vehicle-To-Vehicle Distance Control Mode
Before Cancellation"

6. Do not place anything in the space shown in the figure (view from top).
NOTE:
In case the space shown in the illustration is not available, make space by covering the side of the target
board with a 400 mm (15.75 in)-size frosted black board or black cloth.
Aiming AdjustmentAKS006YM
CAUTION:

Complete all necessary work for laser beam adjustment until the adjustment completes as shown
in the procedure. If the procedure does not complete, the ICC system is inoperable.

If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
