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 40 km/h (25 MPH) and 144 km/h (90 MPH).
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 1.6 km/h (1 MPH) 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 144 km/h (90 MPH).
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 1.6 km/h (1 MPH) as SET/COAST switch is pushed down.
NOTE:

Conventional (fixed speed) cruise control mode is automatically cancelled when the driving speed lowers
to 32 km/h (20 MPH).

The lowest set speed is 40 km/h (25 MPH).
Check For Cancellation Of Conventional (Fixed Speed) Cruise Control Mode (Normal Driving
Condition) In The Following Cases:
Refer to ACS-12, "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-12, "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.
