Emergency flashers
■Emergency flashers
If the emergency flashers are used for a long time while the EV system is not
operating (while the “READY” indicator is not illuminated), the 12-volt battery
may discharge.
The emergency flashers are used to warn other drivers when the
vehicle has to be stopped in the road due to a breakdown, etc.
Press the switch.
All the turn signal lights will
flash. To turn them off, press
the switch once again.

If your vehicle needs to be towed
Before towingThe following may indicate a problem with your transmission. Contact
your Toyota dealer before towing.
● The EV system is operating bu t the vehicle will not move.
● The vehicle makes an abnormal sound.
If there is a malfunction in the P position control system, or if the 12-
volt battery is discharged, the vehicle cannot be moved with the front
wheels on the ground, as the front wheels may be locked.
In this case, move the vehicle with both front wheels or all four
wheels lifted.
Jump start procedure ( P. 470)
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.

The tire pressure warning light may turn on due to natural causes such
as natural air leaks or tire inflation pressure changes caused by temper-
ature. In this case, adjusting the ti re inflation pressure will turn off the
warning light (after a few minutes).

5-2. Steps to take in an emergency
CAUTION
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle
placard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a differ-
ent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine the
proper tire inflation pr essure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-ti re pressure warning system) that
illuminates a low tire pressure telltal e (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale (tire pre ssure warning light) illumi-
nates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel effi ciency (for electric vehicles, traction
battery efficiency) and tire tread lif e, and may affect the vehicle's han-
dling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper ti re maintenance, an d it is the driver's responsibility to
maintain correct tire pressure, even if under-inflation has not reached the
level to trigger illu mination of the TPMS low ti re pressure telltale (tire
pressure warning light).
