When trouble arises
WARNING
■When removing the 12-volt
battery terminals
Always remove the negative (-)
terminal first. If the positive (+) ter-
minal contacts any metal in the
surrounding area when the posi-
tive (+) terminal is removed, a
spark may occur, l eading to a fire
in addition to electrical shocks
and death or serious injury.
■Avoiding 12-volt battery fires
or explosions
Observe the following precautions
to prevent accidentally igniting the
flammable gas that may be emit-
ted from the 12-volt battery:
●Make sure each jumper cable is
connected to the correct termi-
nal and that it is not unintention-
ally in contact with any other
than the intended terminal.
●Do not allow the other end of
the jumper cable connected to
the “+” terminal to come into
contact with any other parts or
metal surfaces in the area, such
as brackets or unpainted metal.
●Do not allow the + and - clamps
of the jumper cables to come
into contact with each other.
●Do not smoke, use matches,
cigarette lighters or allow open
flame near the 12-volt battery.
■12-volt battery precautions
The 12-volt battery contains poi-
sonous and corrosi ve acidic elec-
trolyte, while related parts contain
lead and lead compounds.
Observe the following precautions
when handling the 12-volt battery:
●When working with the 12-volt
battery, always wear safety
glasses and take care not to
allow any 12-volt battery fluids
(acid) to come into contact with
skin, clothing or the vehicle
body.
●Do not lean over the 12-volt bat-
tery.
●In the event that 1 2-volt battery
fluid comes into contact with the
skin or eyes, immediately wash
the affected area with water and
seek medical attention. Place a
wet sponge or cloth over the
affected area until medical
attention can be received.
●Always wash your hands after
handling the 12-volt battery sup-
port, terminals, and other bat-
tery-related parts.
●Do not allow children near the
12-volt battery.
■After recharging the 12-volt
battery
Have the 12-volt battery
inspected at your Toyota dealer
as soon as possible. If the 12-volt
battery is deteriorating, continued
use may cause the 12-volt battery
to emit a malodorous gas, which
may be detrimenta l to the health
of passengers.
■When replacing the 12-volt
battery
●For information regarding 12-
volt battery rep lacement, con-
tact your Toyota dealer.

Owners Manual_USA_M0C052_en
WARNING
●After replacing, securely attach
the exhaust hose and exhaust
hole plug to the exhaust hole of
the replaced 12-volt battery. If
not properly installed, gases
(hydrogen) may leak into the
vehicle interior, and there is the
possible danger of the gas ignit-
ing and exploding.
NOTICE
■When handling jumper cables
When connecting the jumper
cables, ensure that they do not
become entangled in the cooling
fan.

When trouble arises
■If the engine coolant tem-
perature gauge enters the
red zone or “Engine Cool-
ant Temp High Stop in a
Safe Place See Owner’s
Manual” is shown on the
multi-information display
1 Stop the vehicle in a safe
place and turn off the air con-
ditioning system, and then
stop the hybrid system.
2 If you see steam:
Carefully lift the hood after
the steam subsides.
If you do not see steam:
Carefully lift the hood.
3 After the hybrid system has
cooled down sufficiently,
inspect the hoses, engine
radiator core (radiator) and
intercooler radiator core
(radiator) for any leaks.
If a large amount of coolant leaks,
immediately cont act your Toyota dealer.

4 The coolant level is satisfac-
tory if it is between the “F” or
“FULL” and “L” or “LOW”
lines on the reservoir.
If your vehicle overheats
The following may indicate that your vehicle is overheating.
The needle of the engine coolant temperature gauge ( P.91)
enters the red zone or a loss of engine (hybrid system) power i s
experienced. (For example, the vehicle speed does not
increase.)
 “Engine Coolant Temp High Stop in a Safe Place See Owner’s
Manual” is shown on the multi-information display.
Steam comes out from under the hood.

When trouble arises
6 Start the hybrid system to
check that the radiator cool-
ing fan operates and to check
for coolant leaks from the
radiator or hoses.
7 If the fan is not operating:
Stop the hybrid system
immediately and contact your
Toyota dealer.
If the fan is operating:
Have the vehicle inspected at
the nearest Toyota dealer.
8 Check if “Engine Coolant
Temp High Stop in a Safe
Place See Owner’s Manual”
is shown on the multi-infor-
mation display.
If the message does not disappear:
Stop the hybrid system and contact
your Toyota dealer.
If the message is not displayed:
Have the vehicle i nspected at the
nearest Toyota dealer.
WARNING
■When inspecting under the
hood of your vehicle
Observe the following precau-
tions.
Failure to do so may result in seri-
ous injury such as burns.
●If steam is seen coming from
under the hood, do not open the
hood until the steam has sub-
sided. The engine compart-
ment may be very hot.
●After the hybrid system has
been turned off , check that the
“READY” indicator is off. When
the hybrid system is operating,
the gasoline engine may auto-
matically start, or the cooling fan
may suddenly operate even if
the gasoline engine stops. Do
not touch or approach rotating
parts such as the fan, which
may lead to fingers or clothing
(especially a tie, a scarf or a
muffler) getting caught, resulting
in serious injury.
●Do not loosen the coolant reser-
voir caps, while the hybrid sys-
tem and radiator are hot.
High temperature steam or
coolant could spray out.
NOTICE
■When adding coolant
Add coolant slowly after the
hybrid system has cooled down
sufficiently. Adding cool coolant to
a hot hybrid system too quickly
can cause damage to the hybrid
system.
■To prevent damage to the
cooling system
Observe the following precau-
tions:
●Avoid contaminating the coolant
with foreign matter (such as
sand or dust, etc.,).
●Do not use any coolant additive.

1Stop the hybrid system. Set
the parking brake and shift
the shift lever to P.
2 Remove the mud, snow or
sand from around the rear
wheels.
3 Place wood, stones or some
other material under the rear
wheels to help provide trac-
tion.
4 Restart the hybrid system.
5 Shift the shift lever to D or R
and release the parking
brake. Then, while exercising
caution, depress the acceler-
ator pedal.
■When it is difficult to free the
vehicle
Try the followings.
●Turn off the TRAC
(  P.375)
●Using the rear d ifferential lock*
( P.364)
●Switching the front-wheel drive
control switch* ( P.361)
●Using Crawl Control* ( P.365)
●Using Multi-te rrain Select*
( P.369)
*: If equippedIf the vehicle becomes
stuck
Carry out the following pro-
cedures if the tires spin or
the vehicle becomes stuck
in mud, dirt or snow:
Recovering procedure
WARNING
■When attempting to free a
stuck vehicle
If you choose to push the vehicle
back and forth to free it, make
sure the surrounding area is clear
to avoid striking other vehicles,
objects or people. The vehicle
may also lunge forward or lunge
back suddenly as it becomes free.
Use extreme caution.
■When shifting the shift lever
Be careful not to shift the shift
lever with the accelerator pedal
depressed.
This may lead to unexpected
rapid acceleration of the vehicle
that may cause an accident
resulting in death o r serious injury.
NOTICE
■To avoid damaging the trans-
mission and other compo-
nents
●Avoid spinning the rear wheels
and depressing the accelerator
pedal more than necessary.
●If the vehicle remains stuck
even after these procedures are
performed, the vehicle may
require towing to be freed.
