WARNING
For CVT models, you can cancel the cruise control by shifting the select lever into the "N" position. However, do not shift the lever into the "N" position while driving except in case of emergency. If the select lever is shifted into the "N" position, the engine brake will no longer work.
This could result in an accident.

To resume the cruise control after it has been temporarily canceled and with vehicle speed of approximately 20 mph (30 km/h) or more, press the "RES/SET" switch to the "RES" side to return to the original cruising speed automatically.
