(c) Push down the control switch lever to "-/SET" to set the cruising speed (B).
(d) After releasing the lever, check that the vehicle cruises at the set speed.
2. INSPECT '+' FUNCTION
(a) Set a desired speed as in step 1.
(b) Check that the vehicle speed increases while the control switch lever is pushed up to "+/RES" (C).
(c) Check that the vehicle cruises at the newly set speed when the switch is released (D).
(d) Momentarily (approximately 0.6 seconds) push up the control switch lever to the "+/RES", and then release it. Check that the vehicle speed increases by approximately 1.0 km/h or 1 mph with each lever operation (Tap-up function).
3. INSPECT '-' FUNCTION
(a) Set a desired speed as in step 1.
(b) Check that the vehicle speed decreases while the control switch lever is pushed down to "-/SET" (E).
(c) Check that the vehicle cruises at the newly set speed when the switch is released (F).
(d) Momentarily (approximately 0.6 seconds) push down the control switch to "-/SET", and then release it. Check that the vehicle speed decreases by approximately 1.0 km/h or 1 mph with each lever operation (Tap-down function).
HINT:
- The cruise control system automatically cancels when the vehicle speed decreases to below 40 km/h (25 mph).
4. INSPECT 'CANCEL' FUNCTION
(a) Set a desired speed as in step 1.
