ACTION TESTPFP:00000
ICC System Running TestNKS004CL
NOTE:
ICC system can set VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE and CONVENTIONAL (FIXED
SPEED) CRUISE CONTROL MODE when selector lever is in “D” and “M” position.
VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
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.
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 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 displayed on the dot matrix LCD 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 up.
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 down.
NOTE:
Vehicle-to-vehicle distance control mode is automatically cancelled 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 to the “N” (Neutral) position.
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 brake pedal. Then, check if the speed before cancellation is
restored when pushing up RESUME/ACCELERATE switch with 25 MPH (40 km/h for CANADA models)
or above.
2. Cancel the system by shifting the selector lever to “N”. Then, check if the speed set before the cancella-
tion is restored when RESUME/ACCELERATE switch is pushed up.
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.

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.
