battery or refilling fluid reservoirs.
If your vehicle is equipped with an auxiliary battery,
disconnecting the primary under-hood battery DOES NOT remove
power from all circuits.
If the battery has been disconnected and reconnected, refer to the
Batterysection of theMaintenance and Specificationschapter.
The high-current fuses are coded as follows.
