At 68°F (20°C) the open voltage is 12.3 V or higher. Turn the engine switch off and turn the high beams on for 30 seconds. Slow charge is 5 A maximum.
Type A is an LN3 case, 70Ah or greater, CCA 603A or greater. Type B is an LN4 case, 80Ah or greater, CCA 689A or greater. Type C is an LN4 case, 75Ah or greater, CCA 776A or greater. The book says to consult a dealer for which type. This page does not pick one.
The warning says to always remove the negative terminal first. It does not print a tray-bolt torque.
The amp-hour and CCA figures are minimums. The book does not print a Toyota part number beyond the case size and those floors.

Same repair, different model year. Use the page that matches the truck or car in the driveway. A figure on one year is not a figure for the next.
These guides cover the same kind of work. Their numbers belong to those vehicles, not to this one.
