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.
