If your vehicle needs to be towed
Before towingThe following may indicate a problem with your transmission. Contact
your Toyota dealer before towing.
● The engine is running but  the vehicle will not move.

Emergency towing
If a tow truck is not available in
an emergency, your vehicle may
be temporarily towed using a
cable or chain secured to the
emergency towing eyelet(s).
This should only be attempted
on hard surfaced roads for short
distances at low speeds.
A driver must be in the vehicle to
steer and operate the brakes.
The vehicle’s wheels, drive train,
axles, steering and brakes must
be in good condition.
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 flatbed truck.
Use a safety chain system for all to wing, and abide by all state/pro-
vincial and local laws.
