Plug-in hybrid system
■Charging at a public charging sta-
tion with authentication function
When a door is unlocked during charging, the charging connector is
unlocked and charging will be stopped. In this case, the charging station authentication is canceled and charging
may not be able to restart. Reconnect the charging connector and perform authentication for the charging station.
■Protection function of AC charging
inlet overheating (vehicles with 7 kW onboard traction battery char-ger)
By installing a temperature sensor to the AC charging inlet, prevents parts from melting when the temperature rises due
to foreign matter entering the charging connector. When a certain temperature increase is detected, charging is
stopped immediately and a message is displayed on the multi-information dis-play. After the temperature has
decreased, charging resumes by per- forming the operation to start charging again.
WARNING
■When charging
Observe the following precautions.
Failure to do so may cause an unex-
pected accident, resulting in death or serious injury.
●Connect to a power source suitable
for charging. ( P.124)
●Check that the AC charging cable,
plug and socket are free of foreign matter.
●Before charging, check that the AC charging inlet is not deformed, damaged or corroded, and check
that the inlet is free of foreign mat- ter such as dirt, snow and ice. If there is dirt or dust in these areas,
remove completely before inserting the charging connector.
●Before inserting the charging plug into the charger, make sure there is no dirt or dust on the terminal
areas. If there is dirt or dust in these areas, remove completely before inserting the charging plug.
●Do not get the terminals of the AC charging inlet wet.
●Only use sockets where the plug can be securely inserted.
●Do not bundle or wind the AC charging cable while charging, as
doing so may result in overheating.

2925-1. Before driving
WARNING
●Avoid revving or racing the engine. Running the engine at high speed
while the vehicle is stopped may cause the exhaust system to over-heat, which could result in a fire if
combustible material is nearby.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehicle when it is in the
sun. Doing so may result in the follow-ing:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic material of glasses to
deform or crack.
• Soft drink cans may fracture, caus- ing the contents to spray over the
interior of the vehicle, and may also cause a short circuit in the vehicle’s electrical components.
●Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a
place such as the glove box or on the floor, it may be lit accidentally when luggage is loaded or the seat
is adjusted, causing a fire.
●Do not attach adhesive discs to the
windshield or windows. Do not place containers such as air fresh-eners on the instrument panel or
dashboard. Adhesive discs or con- tainers may act as lenses, causing a fire in the vehicle.
●Do not leave a door or window open if the curved glass is coated
with a metallized film such as a sil- ver-colored one. Reflected sunlight may cause the glass to act as a
lens, causing a fire.
●Always apply the parking brake, shift the shift lever to P, stop the hybrid system and lock the vehicle.
Do not leave the vehicle unat- tended while the “READY” indicator is illuminated.
If the vehicle is parked with the shift lever in P but the parking brake is not set, the vehicle may start to
move, possibly leading to an acci- dent.
●Do not touch the exhaust pipes while the “READY” indicator is illu-minated or immediately after turn-
ing the hybrid system off. Doing so may cause burns.
■When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move
the shift lever or depress the acceler- ator pedal, this could cause an acci-dent or fire due to hybrid system
overheating. Additionally, if the vehi- cle is parked in a poorly ventilated area, exhaust gases may collect and
enter the vehicle, leading to death or a serious health hazard.
■When braking
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause one side of the vehicle to
brake differently than the other side. Also, the parking brake may not securely hold the vehicle.
●If the electronically controlled brake system does not operate, do not fol-
low other vehicles closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be depressed more firmly than usual.
Also, the braking distance will increase. Have your brakes fixed immediately.

3085-1. Before driving
is especially true when driving on
wet or slippery road surfaces.
■Sudden acceleration/steering
input/cornering
Executing sharp turns when towing
may result in the trailer colliding
with your vehicle. Decelerate well in
advance when approaching turns
and take them slowly and carefully
to avoid sudden braking.
■Important points regarding
turning
The wheels of the trailer will travel
closer to the inside of the curve
than the wheels of the vehicle. To
make allowance for this, take the
turns wider than you would nor-
mally do.
■Important points regarding
stability
Vehicle movement resulting from
uneven road surfaces and strong
crosswinds will affect handling. The
vehicle may also be rocked by
passing buses or large trucks. Fre-
quently check behind when moving
alongside such vehicles. As soon
as such vehicle movement occurs,
immediately start to decelerate
smoothly by slowly applying the
brakes. Always steer the vehicle
straight ahead while braking.
■Passing other vehicles
Consider the total combined length
of your vehicle and trailer and
ensure that the vehicle-to-vehicle
distance is sufficient before execut-ing lane changes.
■Transmission information
To maintain engine braking effi-
ciency, when using engine braking,
do not use the transmission in D.
(P.315)
■If the hybrid system overheats
Towing a loaded trailer up a long,
steep incline in temperatures
exceeding 30°C (85°F) may result
in the hybrid system overheating. If
the high coolant temperature warn-
ing light indicates that the hybrid
system is overheating, turn the air
conditioning off immediately, leave
the road and stop the vehicle in a
safe place. (P.578)
■When parking the vehicle
Always place wheel chocks under
the wheels of both the vehicle and
trailer. Firmly set the parking brake
and shift the shift lever to P.
■Break-in schedule
Toyota recommends that vehicles fitted
with new power train components
should not be used for towing trailers for
the first 800 km (500 miles).
■Maintenance
●Maintenance must be performed more
frequently when using the vehicle for
towing due to the greater weight bur-
den placed on the vehicle compared
to normal driving.
●Retighten all bolts securing the hitch-
ing ball and bracket after towing for
approximately 1000 km (600 miles).
■If trailer sway occurs
One or more factors (crosswinds, pass-
ing vehicles, rough roads, etc.) can

Driving
■When the ambient temperature is
low, such as during winter driving
conditions
●When starting the hybrid system, the
flashing time of the “READY” indicator
may be long. Leave the vehicle as it is
until the “READY” indicator is steady
on, as steady means the vehicle is
able to move.
●When the hybrid battery (traction bat-
tery) is extremely cold (below approxi-
mately -30°C [-22°F]) under the
influence of the outside temperature, it
may not be possible to start the hybrid
system. In this case, try to start the
hybrid system again after the tem-
perature of the hybrid battery
increases due to the outside tempera-
ture increase etc.
