3. Inspect and Replace Fluid Levels

Check engine oil: Remove dipstick, wipe clean, reinsert, and check level.
- If low, add the manufacturer-recommended oil type.
Check transmission fluid: Remove dipstick, wipe, and check fluid condition and level.
- If low or dirty, consider a fluid change.

4. Electrical System Check

Inspect battery terminals for corrosion; clean if necessary.
Check voltage with a multimeter; replace the battery if voltage is below 12.6 volts.
