- Engine Performance - Get engine drivability problems (hard starts, rough idling, stalling, diminished power, etc.) corrected ASAP before further damage occurs. Cold weather makes existing problems worse. Replace dirty filters-air, fuel, etc.
- Oil - Change your oil and oil every 3 months or 3,000 miles especially if your driving is mostly stop-and-go or consists of frequent short trips.
- Windshield Wipers - Replace blades yearly. If your climate is harsh, purchase rubber-clad (winter) blades to fight ice build-up. Stock up on windshield washer solvent-you'll be surprised how much you use. Carry an ice-scraper.
- Heater/Defroster - The heater and defroster must be in good working condition for passenger comfort and driver visibility. Newer models have a cabin air filter that should be replaced periodically.
- Lights - Inspect all lights and bulbs; replace burned out bulbs; periodically clean road grime from all lenses. To prevent scratching, never use a dry rag.
- Exhaust System - Your vehicle should be placed on a lift and the exhaust system examined for leaks. The trunk and floor boards should be inspected for small holes. Exhaust fumes can be deadly.
- Carry emergency gear: gloves, boots, blankets, flares, a small shovel, sand or kitty litter, tire chains, and a flash light. Put a few "high-energy" snacks in your glove box.

- Fuel - Put a bottle of fuel de-icer in your tank once a month to help keep moisture from freezing in the fuel line. Note that a full gas tank helps keep moisture from forming.
- Cooling Systems - The cooling system should be completely flushed and refilled about every 24 months. The level, condition, and concentration of the coolant should be checked periodically. (A 50/50 mix of anti-freeze and water is usually recommended.)
Never remove the radiator cap until the engine has thoroughly cooled!
The tightness and condition of drive belts, clamps, and hoses should be checked by a pro.
- Battery - The only accurate way to detect a weak battery is with professional equipment. Routine care: Scrape away corrosion from posts and cable connections; clean all surfaces; re-tighten all connections. If battery caps are removable, check fluid level monthly.
- Tires - Worn tires will be of little use in winter weather. Examine tires for remaining tread life, uneven wearing, and cupping; check the sidewalls for cuts and nicks. Check tire pressures once a month. Check the tires when they are cold, before driving for any distance. Rotate as recommended. Don't forget your spare, and be sure the jack is in good condition.
