At 68°F (20°C) the open voltage is 12.3 V or higher. The table says to turn the engine switch off and turn the high beams on for 30 seconds. Slow charge is 5 A maximum.
Use a genuine battery specifically for the Stop and Start system, and a battery that conforms to European regulations. 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 the truck uses. This page does not pick one.
The warning says to always remove the negative terminal first. The emergency section prints that warning with the jump-start precautions. It does not print a tray-bolt torque.
The three types are minimums. The book says the 20-hour rate should be equivalent to those figures or greater, and the CCA the same way. It does not print a Toyota part number beyond the case size, the amp-hour floor, and the CCA floor.

Open voltage at 68°F (20°C) is 12.3 V or higher, measured with the engine switch off and the high beams on for 30 seconds. Slow charge is 5 A max. Stop and Start uses a genuine battery of type A (LN3, 70Ah, 603A), type B (LN4, 80Ah, 689A), or type C (LN4, 75Ah, 776A). The book says to consult a dealer for which type.
The negative terminal. The warning says a spark can occur if the positive terminal is removed first and it touches metal.
The maintenance checklist is on the site now. The email list is not sending yet, so this box will not store an address.
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.
