Toyota chart scope: These rows describe Toyota TrueStart replacement-battery applications, subject to the listed engine and option. They do not establish the factory-installed battery for an individual VIN or approve a third-party product.
Before ordering tires
Read the driver-door tire placard. Match the installed wheel, axle, tire class, load index, speed rating and any OE marking. The size alone cannot approve a replacement SKU. Tire-sidewall maximum pressure is not your vehicle’s cold inflation pressure.
Before ordering a battery
Check the actual battery position, chemistry, voltage, terminals, tray, hold-down, vent, CCA requirement and any BMS registration procedure. Group size alone does not approve a replacement SKU. High-voltage traction batteries are outside this guide.
