AUTO-CRUISE CONTROL MAIN SWITCH CHECK

1. Turn the ignition switch to the "ON" position. 
2. Check that the indicator light within the combination meter 

illuminates when the main switch is switched "ON".

AUTO-CRUISE CONTROL SETTING

1. Switch "ON" the main switch.
2. Drive at the desired speed, above approximately 40 km/h. 

(25 mph)

3. Push the auto-cruise control switch in the direction of arrow.
4. Check to be sure that when the switch is released the speed 

is the desired constant speed.
NOTE: If the vehicles speed decreases to approximately 15 
km/h (9 mph) below the set speed because of climbing a hill 
for example, the auto-cruise control will be cancelled.
