Battery

The battery supplies power to start the engine and operate any additional electrical accessories.

• To avoid break-down or failure to start the vehicle, maintain a battery with full cranking power.

• Trained dealer technicians have the diagnostic equipment to test the battery and ensure that the connections and cables are corrosion-free.
