Be sure to disconnect the battery before cleaning the terminals to avoid any accidental electrical shock.

In addition to cleaning and inspecting electrical components, it is also important to ensure that all electrical connections are secure and tight. Loose connections can cause electrical problems such as intermittent power loss, flickering lights, or warning lights on the dashboard. Check all electrical connections regularly and tighten any that are loose.

Lastly, keep an eye on any warning lights or abnormal electrical behavior. Any warning light that appears on the dashboard should be taken seriously and investigated immediately. Ignoring warning lights can lead to more serious problems down the road. If there is any abnormal electrical behavior, it is best to have the vehicle inspected by a qualified technician to determine the root cause of the issue.

7.5. Scheduled tune-ups and inspections

Regular tune-ups and inspections are essential for the maintenance of your Daihatsu Rocky. These checkups can help identify any potential problems before they become major issues. It is recommended to have a tune-up every 30,000 miles or 2 years, whichever comes first.

During a tune-up, a mechanic will check various components of your vehicle, including the engine, fuel system, and ignition system. They will also check and replace spark plugs, fuel filters, air filters, and other components as needed.

Regular inspections can help prevent breakdowns and accidents by ensuring that your vehicle is running smoothly and safely. A typical inspection includes checking the brakes, steering and suspension systems, tires, and lights.

By scheduling regular tune-ups and inspections, you can extend the life of your Daihatsu Rocky and prevent costly repairs down the line. Additionally, following the manufacturer's recommended maintenance schedule can also help maintain the resale value of your vehicle.
