If your vehicle needs to be towed
Before towingThe following may indicate a problem with your transmission. Contact
your Toyota dealer before towing.
● The hybrid system is operating, but the vehicle will not move.
● The vehicle makes an abnormal sound.
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. This should only be attempted on hard, surfaced roads
for short distances below 18 mph (30 km/h). 
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 a flat bed truck. 
Use a safety chain system for all to wing, and abide by all state/pro-
vincial and local laws.
If towing from the front, the vehicle ’s rear wheel and axles must be in
good condition. ( P. 491)
If they are damaged, use a towing dolly or flat bed truck.

steering will not function, making steering and braking more difficult.

■If the tire pressure warning light comes on after blinking for 1
minute frequently
If the tire pressure warning light comes on after blinking for 1 minute fre-
quently when the “POWER” switch is

tional to alert the driver and front passenger that the seat belts are not fas-
tened.

The steering wheel may become extremely heavy. 
If the steering wheel becomes heavier than usual when operating, firmly
hold and operate it using more force than usual.

Be sure to observe the following precautions. Failure to do so could
cause loss of vehicle control and result in death or serious injury.
