Check For MAIN Switch
1. Start engine. Then, check if the following operations are per-
formed correctly.
2. Vehicle-to-vehicle distance control mode is displayed in combi-
nation meter and “CRUISE” is illuminated when MAIN switch is
pressed “ON” for less than 1.5 seconds and ready for operation.
The illumination goes off when MAIN switch is turned to OFF.
3. “CRUISE” illumination and dot matrix LCD go off when the igni-
tion switch is turned to OFF while MAIN switch is ON (“CRUISE”
illumination is ON and vehicle-to-vehicle distance control mode
is ready for operation).
Check For RESUME/ACCELERATE, SET/COAST, CANCEL Switches
1. Check if RESUME/ACCELERATE, SET/COAST, CANCEL switches are operated smoothly.
2. Check if switches come up as hand is released from the switches.
Check For Distance Switch
1. Start engine.
2. Press the MAIN 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 MAIN 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 down the SET/COAST switch.
4. Confirm that the desired speed is set as hand is released from the SET/COAST switch.
NOTE:
The set vehicle speed is not displayed on the dot matrix LCD in the combination meter.

Check For Increase Of 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 RESUME/ACCELERATE
switch is pushed up.
NOTE:
If the RESUME/ACCELERATE switch is kept pushing 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 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 SET/COAST switch is
pushed down.
NOTE:
Conventional (fixed speed) cruise control mode is automatically cancelled when the driving speed lowers
to 20 MPH (32 km/h for CANADA models).
The lowest set speed is 25 MPH (40 km/h for CANADA models).
Check For Cancellation Of Conventional (Fixed Speed) Cruise Control Mode (Normal Driving
Condition) In The Following Cases:
Refer to ACS-10, "Check For Cancellation Of Vehicle-To-Vehicle Distance Control Mode (Normal Driving Con-
dition) In The Following Cases:" .
Check For Restoring Speed That Is Set By Conventional (Fixed Speed) Cruise Control Mode
Before ICC Cancellation
Refer to ACS-10, "Check For Restoring Speed That Is Set By Vehicle-To-Vehicle Distance Control Mode
Before Cancellation" .
Check For MAIN Switch
1. Start engine. Then, check if the following operations are per-
formed correctly.
2. “CRUISE” lamp illuminates and dot matrix LCD goes off when
MAIN switch is pressed “ON” for more than 1.5 seconds, and
then ready for operation. The illumination goes off when MAIN
switch is turned to OFF.
3. “CRUISE” illumination go off when the ignition switch is turned to
OFF while MAIN switch is ON.
Check For RESUME/ACCELERATE, SET/COAST, CANCEL Switches
1. Check if RESUME/ACCELERATE, SET/COAST, CANCEL switches are operated smoothly.
2. Check if switches come up as hand is released from the switches.

LASER BEAM AIMING ADJUSTMENTPFP:00026
OutlineNKS004CM
Adjust the laser beam aiming every time the ICC sensor integrated unit is removed or installed.
CAUTION:
Adjust laser beam aiming at a horizontal place as far as 12 m (39 ft) forward the vehicle can be
seen.
Adjust laser beam aiming 5 seconds after starting engine.
Never view ICC sensor integrated unit body window directly during laser beam aiming adjustment.
Follow the CONSULT-II when adjusting the laser beam aiming (laser beam aiming adjustment can-
not be operated without CONSULT-II).
Never ride on vehicle during laser beam aiming adjustment.
Idle and turn headlamps OFF during laser beam aiming adjustment.
PreparationNKS004CN
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 integrated unit with a soft cloth.
Remove the front bumper grille. Refer to EI-13, "Removal and
Installation of Front Bumper Grille" .
Outline of Adjustment ProcedureNKS004CO
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 integrated unit automatically adjust the right-left position.)
Setting the ICC Target BoardNKS004CP
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 28 mm (1.10 in) below the center.
