If your vehicle needs to be towed
Before towingThe following may indicate a problem with your hybrid transmission.
Contact your Toyota dealer before towing.
● The hybrid system is operating but the vehicle will not move.
● The vehicle makes an abnormal sound.
If there is a malfunction in the P position control system, the smart
key system or the immobilizer system , or if the 12-volt battery is dis-
charged, the vehicle cannot be tow ed with the front wheels on the
ground, as the front wheels may be locked. In this case, transport the
vehicle with both front wheels or all four wheels lifted.
If towing is necessary, we recommend having your vehicle towed by
your Toyota dealer or a commerci al towing service, using a lift-type
truck or flat bed truck.
Use a safety chain system for all to wing, and abide by all state/pro-
vincial and local laws.
