      4. B0071BG

        When any of the following are performed, check that cruise control system control of vehicle speed is canceled and that the normal driving mode (no control of vehicle speed by the cruise control system) resumes.


        • Depressing the brake pedal.

        • Moving the shift lever from D or S to any other position.

        • Selecting the S3, S2 or S1 range with the shift lever in S.

        • Pushing the CANCEL switch.

        • Turning the cruise control system off using the cruise control main switch (the stored vehicle speed in the ECM is not maintained).

      3. B0071GD

        Push the -SET switch.

      4. Cancel cruise control system control of vehicle speed by performing any of the above operations (other than turning the cruise control system off using the -SET switch).

      5. B00718S

        After pushing the +RES switch at a speed of more than 40 km/h (25 mph), check that the vehicle resumes the speed set prior to cancellation.
