■The compact spare tire (if equipped)
● The compact spare tire is identified by the label “TEMPORARY USE ONLY”
on the tire sidewall.
Use the compact spare tire temporarily, and only in an emergenc y.
● Make sure to check the tire inflation pressure of the compact spare tire.
( P. 774)
■ When using the compact spare tire (if equipped)
As the compact spare tire is not equipped with a tire pressure warning valve
and transmitter, low inflation pressure of the spare tire will not be indicated by
the tire pressure warning system. Also, if you replace the comp act spare tire
after the tire pressure warning light comes on, the light remai ns on.
■ When the compact spare tire is equipped (if equipped)
The vehicle height may become lower when driving with the compa ct spare
tire compared to when driving with standard tires.
■ If you have a flat front tire on a road covered with snow or ice (vehicles
with compact spare tire)
Install the compact spare tire on one of the rear wheels of the vehicle. Per-
form the following steps and fit tire chains to the front tires :
Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of the vehicle.
Fit tire chains to the front tires.

NOTICE
■Be careful when driving over bumps with the compact spare tire
installed on the vehicle. (if equipped)
The vehicle height may become lo wer when driving with the compact spare
tire, compared to when driving with standard tires. Be careful when driving
over uneven road surfaces.
■ Driving with tire chains and the compact spare tire (if equipped)
Do not fit tire chains to the compact spare tire.
Tire chains may damage the vehicle body and adversely affect dr iving per-
formance.
■ When replacing the tires
When removing or fitting the wheels, tires or the tire pressure warning valve
and transmitter, contact any authorized Toyota retailer or Toyo ta authorized
repairer, or any reliable repaire r as the tire pressure warning valve and
transmitter may be damaged if not handled correctly.
■ To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid sealants, the tire pressure warning valve
and transmitter may not operate properly. If a liquid sealant i s used, contact
any authorized Toyota retailer or Toyota authorized repairer, o r any reliable
repairer or other qualified service shop as soon as possible.

■Stopping the hybrid system
Set the parking brake, shift the shift lever to P and press the power switch as
you normally do when stopping the hybrid system.
■ Replacing the key battery
As the above procedure is a temporary measure, it is recommende d that the
electronic key battery be replaced immediately when the battery is depleted.
( P. 643)
■ Alarm (if equipped)
Using the mechanical key to lock the doors will not set the ala rm system.

When trouble arises
WARNING
■When removing the 12-volt battery terminals
Always remove the negative (-) terminal first. If the positive (+) terminal con-
tacts any metal in the surrounding area when the positive (+) t erminal is
removed, a spark may occur, leading to a fire in addition to el ectrical shocks
and death or serious injury.
■ Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally ignit ing the flam-
mable gas that may be emitted from the 12-volt battery:
● Make sure each jumper cable is connected to the correct terminal and that
it is not unintentionally in contact with any other than the in tended terminal.
● Do not allow the other end of the jumper cable connected to the “+” termi-
nal 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 poisonous and corrosive acidic ele ctrolyte,
while related parts contain lead and lead compounds. Observe th e 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 battery fluids (acid) to come into c ontact with
skin, clothing or the vehicle body.
● Do not lean over the 12-volt battery.
● In the event that 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 medica l attention
can be received.
● Always wash your hands after handling the 12-volt battery support, termi-
nals, and other battery-related parts.
● Do not allow children near the 12-volt battery.

WARNING
■After recharging the 12-volt battery (M20A-FXS engine)
Have the 12-volt battery inspected at any authorized Toyota ret ailer or
Toyota authorized repairer, or any reliable repairer as soon as possible. If
the 12-volt battery is deteriorating, continued use may cause t he 12-volt
battery to emit a malodorous gas, which may be detrimental to t he health of
passengers.
■ When replacing the 12-volt battery
● When the vent plug and indicator are close to the hold down clamp, the
battery fluid (sulfuric acid) may leak.
● For information regarding 12-volt battery replacement, contact any autho-
rized Toyota retailer or Toyota authorized repairer, or any rel iable repairer.
● M20A-FXS engine: After exchanging, securely attach the exhaust hose
and exhaust hole plug to the exhaust hole of the exchanged 12-v olt bat-
tery. If not properly installed, gases (hydrogen) may leak into the vehicle
interior, and there is the possible danger of the gas igniting and exploding.
NOTICE
■When handling jumper cables
When connecting the jumper cables, ensure that they do not beco me entan-
gled in the cooling fans, etc.
■ To prevent damaging the vehicle (M20A-FXS engine)
The exclusive jump starting terminal is to be used when chargin g the 12-volt
battery from another vehicle in an emergency. It cannot be used to jump
start another vehicle.

When trouble arises
If your vehicle overheats
●The needle of the engine coolant temperature gauge (P. 1 6 4 )
enters the red zone or a loss of hybrid system power is experi-
enced. (For example, the vehicle speed does not increase.)
● “Hybrid System Overheated Reduced Output Power.” is shown on
the multi-information display.
● Steam comes out from under the hood.
■If the high coolant temperature warning light comes on
Stop the vehicle in a safe place and turn off the air condition ing
system, and then stop the hybrid system.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the hybrid system has cooled down sufficiently, inspect t he
hoses and radiator core (radiator) for any leaks.
Radiator
Cooling fans
If a large amount of coolant leaks, immediately contact any aut ho-
rized Toyota retailer or Toyota authorized repairer, or any rel iable
repairer.
The following may indicate that your vehicle is overheating.

When trouble arises
WARNING
■To prevent an accident or injury when inspecting under the hood of
your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
● If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot.
● After the hybrid system has been turned off, check that the indicator on the
power switch and the “READY” indicator are off.
When the hybrid system is operating, the gasoline engine may au tomati-
cally start, or the cooling fans may suddenly operate even if t he gasoline
engine stops. Do not touch or approach rotating parts such as t he fan,
which may lead to fingers or clothing (especially a tie, a scar f or a muffler)
getting caught, resulting in serious injury.
● Do not loosen the coolant reservoir caps while the hybrid system and radi-
ator are hot.
High temperature steam or coolant could spray out.
NOTICE
■ When adding engine/power control unit coolant
Add coolant slowly after the hybrid system has cooled down suff iciently.
Adding cool coolant to a hot hybrid system too quickly can caus e damage to
the hybrid system.
■ To prevent damage to the cooling system
Observe the following precautions:
● Avoid contaminating the coolant with foreign matter (such as sand or dust,
etc.).
● Do not use any coolant additive.
