VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
Set Checking
1. Press the MAIN 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 SET/COAST switch.
4. Confirm that the desired speed is set as hand is released from the SET/COAST 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 meter.
Check For Increase Of 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 RESUME/ACCELERATE 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 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 SET/COAST 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 Cancellation Of Vehicle-To-Vehicle Distance Control Mode (Normal Driving Condi-
tion) In The Following Cases:
1. When the brake pedal is depressed after the system is turned ON.
2. When the selector lever is shifted into other than “D” including manual shift.
3. When the MAIN switch is turned OFF.
4. When CANCEL switch is operated.
Check For Restoring 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 RESUME/ACCELERATE switch with 25 MPH (40 km/h for CANADA models) or
above.
2. Cancel the system by shifting the selector lever into other than “D”. Then, check if the speed set before the cancellation is restored when RESUME/ACCELERATE switch is pressed.
3. Check if the speed previously set is restored when RESUME/ACCELERATE switch is operated with driv- ing 25 MPH (40 km/h for CANADA models), after canceling vehicle-to-vehicle distance control mode by
operating the CANCEL switch.

LASER BEAM AIMING ADJUSTMENT
Revision: 2005 July 2005 FX
LASER BEAM AIMING ADJUSTMENTPFP:00026
OutlineAKS006YI
Adjust the laser beam aiming every time the ICC sensor is removed or installed.
CAUTION:

Place the vehicle on the level ground when the laser beam aiming adjustment is operated.

Follow the CONSULT-II when adjusting the laser beam aiming (laser beam aiming adjustment can-
not be operated without CONSULT-II).
PreparationAKS006YJ

Adjust the tire pressure to the specified value.

See that there is no load in the vehicle.

Coolant, engine oil filled up to correct level and full fuel tank.

Shift the gear into “P” position and release the parking brake.

Clean the ICC sensor with a soft cloth.
Outline of Adjustment ProcedureAKS006YK
1. Set up the ICC target board [KV99110100 (J-45718)].
2. Adjust the sensor following the procedure on CONSULT-II. (Turn manually the screw for up-down position adjustment. ICC sensor automatically adjust the right-left position.)
Setting the ICC Target BoardAKS006YL
Accurate ICC target board setting is required for the laser beam aiming adjustment.
CAUTION:
ICC system does not function normally if laser beam aiming is not accurate.
ADJUSTING HEIGHT OF THE TARGET
1. Attach a triangle scale at the center.

LASER BEAM AIMING ADJUSTMENT
Revision: 2005 July 2005 FX
5. Pivot the edge of the target board 20° to either side.
NOTE:
Approx. 50 mm (1.97 in) shift rates the 20 ° movement.
6. Do not place anything in the space shown in the figure (view from top). NOTE:
In case the space shown in the figure 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.
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER on the data link connector.

A/T CONTROL SYSTEM
Revision: 2005 July 2005 FX
Shift MechanismACS002LE
The automatic transmission uses compact triple planetary gear systems to improve power transmission effi-
ciency, simplify construction and reduce weight.
It also employs an optimum shift control and super wide gear ratios. They improve starting performance and
acceleration during medium and high-speed operation.
