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.

CAUTION
■Caution while towing
●Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive
stress on the emergency towing eyelets and the cables or chains. Always
be cautious of the surroundings and other vehicles while towing.
● Do not turn the “POWER” switch off.
This may lead to an accident as the front wheels will be locked by the
parking lock.
● If the hybrid system is off, the power assist for the brakes and steering will
not function, making steering and braking more difficult.
■ Installing towing eyelets to the vehicle
Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing. This
may lead to accidents that cause serious injury or even death.
