   In many families, the time leading up to a vacation is spent making a list and checking off items such as stop mail, turn off water, call kennel. However, an item that should be at the top of this list —check the car— is often overlooked.
   
  *Gas Tank
    Keep the gas tank at least half full. This helps control condensation inside       the tank, keeping your fuel free of water. It may also save you from       running out of gas in an unexpected traffic jam.
  
  *Air Filter
    Change your air filter at recommended intervals. According to government       statistics, a clogged air filter can cause up to a 10% increase in fuel       consumption.
  
  *Dead Battery   
    A dead battery is one of the most common reasons for a breakdown.       Carry an auxiliary power source to boost a dead battery.
  
  *Headlights  
    Tests have shown daytime lighting helps cut accident rates. If your vehicle       is not equipped with headlights that turn on automatically, consider       turning them on both day and night for optimum safety.
  
  *Parking Brakes  
    Use your parking brake every time you get out of your car. This good habit       will come in handy in hilly terrain.
