The first 100 days of ownership set the tone for your vehicle's health, reliability, and resale value. A few smart moves now prevent problems later.

## First week essentials

Review your owner's manual-it covers maintenance schedules, tire pressure, fluid types, and warning lights specific to your model. Confirm your insurance and registration are in place. Familiarize yourself with all the controls and features. Take time learning infotainment, climate, and safety systems.

## Break-in period

Modern cars don't require a hard break-in, but avoid extreme acceleration, hard braking, and highway speeds for the first 500 miles. Let the engine, transmission, and drivetrain settle in gently. This gives moving parts time to bed in smoothly.

## First service visit

Schedule your first oil change and inspection around 1,000 miles or per the manual. This catches any early issues and gets service records started. Maintain the schedule afterward-it's your best defense against costly repairs.
