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.
Low-voltage battery groups
| Engine / trim | Position | Observed group | Technology | Condition | Source ID |
|---|---|---|---|---|---|
| ZN8; FA24 | primary_low_voltage | 35 | Not documented | Not documented | OEM-TOYOTA-TRUESTART-2025-2026 |
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 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.
What to verify next
- Match the exact year and factory options.
- Read the door placard and installed tire sidewall or the installed battery label.
- Compare an exact replacement SKU with the OEM requirements and ask a qualified installer when a condition remains unknown.
