What is it?
Your car’s starting and charging systems, and the battery, help ensure dependable vehicle operation whenever you drive your car and in all sorts of driving conditions. Make sure to check these systems regularly.

What does it do?
The battery stores electrical energy and the starter converts that energy into mechanical force to turn the engine for starting. The alternator produces electric current to replace what the starter used during start-up and to support electrical loads when the engine is running. An ignition module turns the low-voltage supply to the ignition coil on and off, and the coil produces the high voltage for the ignition system. This creates a spark at the spark plugs and ignites the air/fuel mixture in the engine. A belt transmits power from the front of the engine to the alternator’s pulley, along with other accessories.

Typical Wear and Tear
Driving habits such as frequent engine on/off cycles will cause more wear on the starter than a simple trip back and forth to work. Other factors include:

  • Driving and weather conditions
  • Mileage
  • Vehicle age
  • Excessive electrical draws like in-vehicle entertainment systems


  • Headlights and interior lights dim
  • “Check Engine” and/or battery light may come on
  • Accessories fail to operate


What is it?
Lights and wipers play a major role in safe driving – the chances for accidents increase if you can’t see or be seen. Some states have laws that require the headlights to be on with the wipers. If you detect any problems with your car’s lights or wipers, have them checked out at once.

What does it do?
The wiper system keeps excessive water, snow or dirt from building up on the windshield and removes them to maintain clear visibility through the windshield. The lighting system provides nighttime visibility, signals and alerts other drivers, and supplies light for viewing instruments and the vehicle’s interior.

Typical Wear and Tear
Lights and wipers are normal wear items that require periodic replacement. Factors affecting replacement intervals include:

  • Operating conditions (winter conditions are tough on wiper blades)
  • Frequency of use
  • Material and type of lights and wipers
  • Sunny weather – wiper blades can deteriorate faster and need more frequent replacement in desert states

Your Fuel System

What is it?
You car’s fuel system works with the rest of the engine control system to deliver the best performance with the lowest emissions. Check your car’s fuel system regularly or immediately if you smell gas or suspect a problem.

What does it do?
The fuel system transfers fuel from the fuel tank and passes it through a fuel filter for straining before it arrives at the injectors. A pressure regulator controls fuel pressure to ensure good engine performance under a variety of speed and load conditions. Fuel injectors, when activated, spray a metered amount of fuel into the engine. Some vehicles use a return line system to return unused fuel back to the tank.

Typical Wear and Tear
Intervals for fuel system maintenance may be influenced by:

  • Fuel quality
  • Vehicle age
  • Mileage/time
  • Operating conditions
  • Maintenance history


  • Poor fuel economy
  • Vehicle won’t start
  • “Check Engine” light is illuminated
