Before towing
The following may indicate a problem with your transmission. Contact
your Toyota dealer before towing.

If towing is necessary, we recommend having your vehicle towed by
your Toyota dealer or a commercial towing service, using a lift-type
truck or a flat bed truck.
Use a safety chain system for all towing, and abide by all state/pro-
vincial and local laws.
2WD models only: If towing from the front, the vehicle's rear wheels
and axles must be in good condition. (
