Fluids And Leaks
- Engine oil: Verify level on the dipstick; note color and odor. Top off only with the specified grade.
- Coolant and washer fluid: Check reservoir markings; never open a hot cooling system.
- Brake fluid: Confirm the level between MIN and MAX; schedule an inspection if it is low or dark.
- Under-vehicle sweep: Inspect the ground for fresh spots indicating leaks after parking overnight.
Visibility And Lighting
- Wipers and windshield: Inspect blades for cracking or streaking; clean the glass inside and out.
- Exterior lights: Test headlights (low/high), DRLs, turn signals, hazards, brake lights, and reverse lights; replace failed bulbs promptly and clean hazed lenses.
Battery And Electrical
- Terminals: Ensure clamps are tight and free of corrosion.
- Cranking behavior: Slow starts, dimming lights, or repeated jump starts suggest testing is needed.
- Accessory check: Operate HVAC, defrosters, power windows, and infotainment to confirm normal function.
Under-Hood And Belts
- Belts and hoses: Press gently to check tension and flexibility; look for fraying, glazing, swelling, or soft spots.
- Air filter (quick view): If accessible, inspect for heavy dirt or debris and note for replacement.
Cabin Safety And Cleanliness
- Seat belts and latches: Confirm smooth retraction and secure locking.
