- Turn the cruise control main switch off when not using the cruise control system.
- Be careful as the vehicle speed increases when driving downhill with the cruise control system on.
- The + (ACCEL)/RES (RESUME) operation changes according to the cruise control system status. When the cruise control system is operating, the + (ACCEL) function operates. When the cruise control system is not operating, the RES (RESUME) function operates.
