7-2. Steps to take in an emergency
If your vehicle needs to be towed
If towing is necessary, we recommend having your vehicle
towed by your Toyota dealer or a commercial towing service,
using a wheel-lift type truck or flatbed truck.
Use a safety chain system for all towing, and abide by all state/
provincial and local laws.
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When towing the vehicle
■While towing
●When towing using cables or chains, avoid sudden starts, etc. which place
excessive stress on the towing eyelets, cables or chains. The towing eye-
lets, cables or chains may become damaged, broken debris may hit peo-
ple, and cause serious damage.
●Do not turn the power switch off.
There is a possibility that the steering wheel is locked and cannot be oper-
ated.
Be sure to transport the vehicle with the
front wheels raised or with all four wheels
raised off the ground. If the vehicle is
towed with the front wheels contacting
the ground, the drivetrain and related
parts may be damaged or electricity gen-
erated by the operation of the motor may
cause a fire to occur depending on the
nature of the damage or malfunction.

4527-2. Steps to take in an emergency
The following may indicate a problem with your transmission. Contact
your Toyota dealer or commercial towing service before towing.
●The hybrid system warning message is shown on the multi-informa-
tion display and the vehicle does not move.
●The vehicle makes an abnormal sound.
NOTICE
■To prevent damage to the vehicle when towing using a wheel-lift type
truck
●Do not tow the vehicle from the rear when the power switch is off. The
steering lock mechanism is not strong enough to hold the front wheels
straight.
●When raising the vehicle, ensure adequate ground clearance for towing at
the opposite end of the raised vehicle. Without adequate clearance, the
vehicle could be damaged while being towed.
■To prevent damage to the vehicle when towing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
■To prevent damage to the vehicle during emergency towing
Do not secure cables or chains to the suspension components.
