Inspecting and maintaining the charging cable
WARNING
QRoutine inspection
Check the following points regularly.
Failure to do so may cause an unexpected accident, resulting in death or
serious injury.
O The charging cable, plug, charging connector, CCID (Charging Circuit
Interrupting Device) etc. have not been damaged
O The socket has not been damaged
O The plug can be securely inserted into the socket
O The plug does not get extremely hot during use
O The tip of the plug has not been deformed
O The plug is not dirtied by dust etc.
Remove the plug from the socket before inspecting it. If any ab normalities
are found in the charging cable as a result of the inspection, immediately
stop use and consult any authorized Toyota retailer or Toyota a uthorized
repairer, or any reliable repairer.
Q Maintaining the charging cable
When the charging cable is dirty, first remove the dirt with a hard, wringed
cloth, and then wipe the cable with a dry cloth.
However, never wash it with water. If the charging cable is was hed with
water, fire or electric shock may occur during charging, possib ly resulting in
death or serious injury.
Q When not using the charging cable for a long time
Remove the plug from the socket. Dust could accumulate on the p lug or in
the socket, possibly causing overheating which could lead to a fire.
Also, keep the cable in a place free from moisture.

WARNING
QIf a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning li ght not
come on when you start the hybrid system, this could mean that these sys-
tems are not available to help protect you in an accident, whic h could result
in death or serious injury. Have the vehicle inspected by any a uthorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer imme-
diately if this occurs.
NOTICE
Q To prevent damage to the engine and its components
The engine may be overheating if the high coolant temperature w arning
light comes on or flashes. In this case, immediately stop the v ehicle in a
safe place, and check the engine after it has cooled completely . (P. 703)

Driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
Q When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidental ly move the
shift lever or depress the accelerator pedal, this could cause an accident or
fire due to hybrid system overheating. Additionally, if the veh icle is parked in
a poorly ventilated area, exhaust gases may collect and enter t he vehicle,
leading to death or a serious health hazard.
Q When braking
O When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this ma y cause
one side of the vehicle to brake differently than the other sid e. Also, the
parking brake may not securely hold the vehicle.
O If the electronically controlled assist function does not operate, do not fol-
low other vehicles closely and avoid downhill or sharp turns th at require
braking.
In this case, braking is still possible, but the brake pedal sh ould be
depressed more firmly than usual. Also, the braking distance wi ll increase.
Have your brakes fixed immediately.
O The brake system consists of 2 or more individual hydraulic systems; if
one of the systems fails, the other(s) will still operate. In t his case, the
brake pedal should be depressed more firmly than usual and the braking
distance will increase. Have your brakes fixed immediately.

Driving
QAutomatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automatically
re-enabled in the following situations:
OWhen the power switch is turned off
OIf only the TRC system is turned off, the TRC will turn on when vehicle
speed increases
If both the TRC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.
QReduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the hybrid system
off. The EPS system should return to normal within 10 minutes.
QElectric power steering system warning light (warning buzzer)
P. 658
QOperating conditions of emergency brake signal
When the following conditions are met, the emergency brake signal will oper-
ate:
OThe emergency flashers are off.
OActual vehicle speed is over 55 km/h (35 mph).
OThe system judges from the vehicle deceleration that this is a sudden brak-
ing operation.
QAutomatic system cancelation of emergency brake signal
The emergency brake signal will be canceled in any of the following situa-
tions:
OThe emergency flashers are turned on.
OThe system judges from the vehicle deceleration that is not a sudden brak-
