Summary

TSB: The purpose of this Service Bulletin is to provide best practices for towing/flatbed transporting 2018 model year LC 500, LC 500h, LS 500, and LS 500h 2WD vehicles. Incorrect towing methods may cause the vehicle to exhibit a bent front height adjustment sensor bracket. This condition may cause headlight misalignment when auto adjusting based on the vehicle height position, and in some cases, will set a Diagnostic Trouble Code (DTC). NOTICE ? If the vehicle is NOT towed correctly, the front height adjustment sensor bracket may be vulnerable to damage due to the layout of the front suspension. ? When shipping a vehicle, some third-party towing companies that use flatbed trucks do NOT follow the recommendations found in the Owner?s Manual to secure the vehicle. For example, some towing companies may secure the vehicle with metal hooks around the front lower control arms as a mount point. The front height adjustment sensor bracket is fixed to the lower control arm, and using this method risks bending the bracket if the strap or chain contacts this bracket under load. Toyota Motor North America (TMNA) recommends that dealers ensure towing companies are aware of proper hook and tie-down points and the risks if not performed properly. Customers should be educated in situations when non-dealer roadside assistance is used. If the vehicle has a damaged front height adjustment sensor bracket after being towed by a third-party towing company, please advise the dealer service department immediately, as the towing company may be responsible for damages.
