Examination
1. Check the fuse.
2. Check the operation of the brake light switch (voltage from the switch deactivates the cruise control system).
3. If the brake lights do not come on or do not turn off, troubleshoot the cause and retest the cruise control system.
4. Check the freedom of movement of the cruise control cable, replace if necessary.
5. Check the cruise control speed sensor, which is mounted in the speedometer.
6. Check the system operation during a test drive. If the system does not operate normally, contact a car service center.
