This document provides installation instructions for the Thule Kit 145366, designed specifically for the Toyota Crown Crossover (4-door sedan, 2023-). The kit must be used in conjunction with a compatible Thule Foot Pack (sold separately). Always adhere to the maximum load and speed limits to ensure vehicle safety.
Safety and usage limits
- Maximum load capacity: 75 kg (165 lbs). Do not exceed this weight, which includes the weight of the roof rack system itself.

- Maximum speed (with load): 80 km/h (50 mph).
- Always ensure the roof rack is securely fastened before driving.
Assembly and installation
The installation process involves combining the Kit 145366 components with the Thule Foot Pack. Identify the specific parts included in the kit (pads and clamps labeled 383, 384, 584, 1010, and 1011) and match them to the corresponding positions on the vehicle (Front Left, Front Right, Rear Left, Rear Right).

- Assemble the kit components onto the Foot Pack as shown in the assembly diagram.
- Ensure the clamps click into place securely.
- Position the assembled rack on the vehicle roof according to the specific measurements provided in the positioning section.
