system
→ P.228
Immobilizer system
The vehicle’s keys have built-
in transponder chips that pre -
vent the hybrid system from
starting if a key has not been
previously registered in the
vehicle’s on-board computer.
Never leave the keys inside the
vehicle when you leave the
vehicle.
This system is designed to help
prevent vehicle theft but does not
guarantee absol ute security
against all vehicle thefts.

Plug-in hybrid system
gasoline engine needs to be started.*1: The gasoline engine may also oper -
ate in circumstances other than those
listed above, depending on condi -
tions.
*2: When driving in AUTO EV/HV mode.
Even in EV mode, the gasoline
engine may start, depending on the
condition of the hybrid battery (trac -
tion battery).
■If “Engine Started to Protect Sys -
tem EV driving unavailable” is dis - played on the mu lti-information
display
EV driving may be canceled in order to protect the hybr id system, etc.
In this case, perform driving with the
gasoline engine until EV driving will be returned to automatically.
■Conditions in which the gasoline
engine may not stop
The gasoline engine starts and stops automatically. Howev er, it may not stop
automatically in the following condi -
tions*:
●During gasoline engine warm-up
●During hybrid battery (traction battery)
charging
●When the temperature of the hybrid
battery (traction batt ery) is high or low
●When the windshield defogger switch
is pressed. ( →P.453)*: Depending on the circumstances, the
gasoline engine may also not stop
automatically in sit uations other than
those above.
■Sounds and vibrations specific to a
hybrid vehicle
There may be no engine sound or vibra - tion even though the vehicle is able to
move with the “READY” indicator is illu-
minated. For safety, apply the parking brake and make sure to shift the shift
lever to P when parked.
The following sounds o r vibrations may
occur when the hyb rid system is operat- ing and are not a malfunction.
●Motor sounds may be heard from the engine compartment.
●Sounds may be heard from the hybrid battery (traction battery) when the
hybrid system starts or stops.
●Relay operating sounds such as a
snap or soft clank will be emitted from
the hybrid battery ( traction battery), behind the rear seats, when the hybrid
system is started or stopped.
●Sounds from the hy brid system may
be heard when the back door is open.
●Sounds may be heard from the trans -
mission when the gasoline engine
starts or stops, when driving at low speeds, or during idling.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard due to regener - ative braking when t he brake pedal is
depressed or as the accelerator pedal
is released.
●Vibration may be f elt when the gaso-
line engine starts or stops.
●Cooling fan sounds may be heard
from the air intake vent under the rear seat. ( →P.98)
●Sounds may be heard from near the hybrid battery (traction battery) in
accordance with th e operation of the
air conditioning syst em or “Battery Cooler” ( →P.129).
■Maintenance, repair, recycling, and
disposal
Contact any authoriz ed Toyota retailer
or Toyota authorized repairer, or any reliable repairer regarding mainte -
nance, repair, recycling and disposal.
Do not dispose of the vehicle yourself.

982-1. Plug-in hybrid system
There is an air intake vent under
the rear seat for cooling the DC/DC
converter.
Blocking the air intake vent may
prevent the plug-in hybrid system
from operating properly.
When a certain level of impact is
detected by the im pact sensor, the
emergency shut off system blocks
off the high voltage current and
NOTICE
■Notice about fuel
●For plug-in hybrid vehicles, fuel
may remain in the tank for a long time and undergo changes in qual -
ity depending on the how the vehi -
cle is used. Refuel at least 20 L (5.3 gal., 4.4 Imp.gal. ) of fuel every 12
months (refuel a tot al of at least 20
L [5.3 gal., 4.4 Imp.gal.] over a 12-
month period), as this may affect components of the fuel system or
the gasoline engine.
●If the vehicle has not been refueled
for a certain amount of time and it is
possible that the quality of the fuel remaining in the tank has changed,
“No New Fuel has been Added
Recently Please refuel” is displayed on the multi-information display
when the power switch is turned to
ON. If the message is displayed, refuel the vehicle immediately.
DC/DC converter air intake
vent
NOTICE
■DC/DC converter air intake vent
●Make sure not to block the air
intake vent with anything, such as a seat cover, plastic cover, or lug -
gage. Blocking the air intake vent
may prevent the plug-in hybrid sys - tem from operating properly.
●When dust etc. has accumulated in
the air intake ven t, clean it with a vacuum cleaner to prevent the vent
from clogging.
●Do not wet or a llow foreign sub-
stances to enter the air vent as this
may cause a shor t circuit and dam- age the DC/DC converter.
●Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the
DC/DC converter, the converter may be damaged. Have the vehicle
inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
●A filter is installed to the air intake vent. When the filter remains
noticeably dirty even after cleaning
the air intake vent, filter cleaning or replacement is recommended.
When cleaning the filter, refer to
P.536.
●If “Maintenance required for DCDC
converter cooling parts See Owner’s Manual” is shown on the
multi-information display, the air
intake vent and filter may be clogged. Refer to P.536 for informa -
tion on how to clean the air intake
vent.

5-1. Before driving
Driving
■Sudden acceleration/steering
input/cornering
Executing sharp turns when towing
may result in the trailer colliding
with your vehicle. D ecelerate well in
advance when approaching turns
and take them slowly and carefully
to avoid sudden braking.
■Important points regarding
turning
The wheels of the tr ailer 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.321)
■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.611)
■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 factor s (crosswinds, pass- ing vehicles, rough roads, etc.) can
adversely affect handling of your vehicle
and trailer, causing instability.

4505-6. Driving tips
NOTICE
■When you drive through water
If driving through water, such as when
crossing shallow st reams, first check the depth of the water and the bottom
of the riverbed for firmness. Drive
slowly and avoid deep water.
■Inspection after off-road driving
●Sand and mud that has accumu-
lated around brake discs may affect braking efficiency and may damage
brake system components.
●Always perform a maintenance
inspection after each day of off-
road driving that has taken you through rough terrain, sand, mud,
or water.
