Your vehicle is equipped with two or three maintenance-free batteries
mounted in a covered tray located on the left frame rail. The covered
battery tray, depending upon application, may also have one or two steps
attached.

straps on the battery cover and
move them to the side of the
battery in order to remove the lid.

For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make sure you tightly fasten the battery cables to the battery
terminals.
If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.
If you plan to store your vehicle for an extended period, disconnect the
negative battery cable. This minimizes the discharge of your battery
during storage.
If the engine cranks but does not start, remove the battery box cover
and check the 40 amp inline fuse located on the battery cable above the
battery.
Because a computer electronically controls your vehicle’s engine, battery
power controls some conditions. When you disconnect the battery or
install a new battery, the engine must relearn its idle and fuel trim
strategy for optimum driveability and performance. To begin this process:
1. With your vehicle at a complete stop, set the parking brake.
2. Put the gearshift in position P (automatic transmission) or neutral
(manual transmission), turn off all accessories and start the engine.
3. Run the engine until it reaches normal operating temperature.
