Road Test
HINT:
'SET' and '-', 'RES' and '+', 'ON-OFF' functions share the same switch. Operate the cruise control main switch according to the directions ("dn tri", "up tri", "l tri") indicated on the switch.
- INSPECT 'SET' FUNCTION
- Push the ON-OFF button on.
- Drive at a desired speed of 40 km/h (25 mph) or higher.
- Push down the control switch lever to "-/SET".
- After releasing the lever, check that the vehicle cruises at the set speed.
- INSPECT '+' FUNCTION
- Set a desired speed as in step 1.
- Check that vehicle speed increases while the control switch lever is pushed up to "+/RES".
- Check that the vehicle cruises at the newly set speed when the switch is released.
- Momentarily (approximately 0.6 second) push up the control switch lever to the "+/RES", and then release it. Check that vehicle speed increases approximately 1.6 km/h (1 mph) with each lever operation (Tap-up function).
- INSPECT '-' FUNCTION
- Set a desired speed as in step 1.
- Check that vehicle speed decreases while the control switch lever is pushed down to "-/SET".
- Check that the vehicle cruises at the newly set speed when the switch is released.
- Momentarily (approximately 0.6 second) push down the control switch to "-/SET", and then release it. Check that vehicle speed decreases approximately 1.6 km/h (1 mph) with each lever operation (Tap-down function).
HINT:
Cruise control system automatically cancels when the vehicle speed goes below 40 km/h (25 mph).
- INSPECT 'CANCEL' FUNCTION
- Set a desired speed as in step 1.
- Check that the system cancels cruise control when operating one of the following:
- Depressing the brake pedal
- Depressing the clutch pedal (M/T)
