Every 30 days, it's important to check your tire pressure, inspect for excessive wear, and top up the windshield washer fluid as necessary. Every 7,500 miles or so, you'll want to rotate the tires, check the coolant level of the battery, inspect various components like the cabin heater, power inverter, accessory power, and charger modules. Additionally, this interval requires examining brakes, steering, suspension, and chassis components for any unusual wear or damage. It's also crucial to inspect the power steering and drive shafts for signs of wear, lubricate door locks, and check suspension gas struts. Don't forget to check vehicle headlights and replace if needed.
