When trouble arises
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural caus es such as
natural air leaks or tire inflation pressure changes caused by temperature. In
this case, adjusting the tire inflation pressure will turn off the warning light
(after a few minutes).
■ When a tire is replaced with a spare tire (if equipped)
Vehicles with full-size spare tire: The spare tire is also equi pped with a tire
pressure warning valve and transmitter. The tire pressure warni ng light will
turn on if the tire inflation pressure of the spare tire is low . If a tire goes flat,
the tire pressure warning light will not turn off even though t he flat tire has
been replaced with the spare tire. Replace the spare tire with the repaired tire
and adjust the tire inflation pressure. The tire pressure warni ng light will go off
after a few minutes.
Vehicles with compact spare tire: The compact spare tire is not equipped with
a tire pressure warning valve and transmitter. If a tire goes f lat, the tire pres-
sure warning light will not turn off even though the flat tire has been replaced
with the spare tire. Replace the spare tire with the repaired tire and adjust the
tire inflation pressure. The tire pressure warning light will g o off after a few
minutes.
■ Conditions that the tire pressure warning system may not function prop-
erly
 P. 619
■ If the tire pressure warning light frequently comes on after blinking for
1minute
If the tire pressure warning light frequently comes on after bl inking for
1 minute when the power switch is turned to ON mode, have it che cked by
any authorized Toyota retailer or Toyota authorized repairer, o r any reliable
repairer.
■ Warning buzzer
In some cases, the buzzer may not be heard because of noisy pla ce or an
audio sound.

WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any a uthorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer. The
vehicle will become extremely unstable during braking, and the ABS system
may fail, which could cause an accident resulting in death or s erious injury.
■ When the electric power steering system warning light comes on
When the light comes on yellow, the assist to the power steerin g is
restricted. When the light comes on red, the assist to the powe r steering is
lost and handling operations of the steering wheel become extre mely
heavy. When steering wheel operations are heavier than usual, g rip the
steering wheel firmly and operate it using more force than usua l.
■ If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause a
loss of vehicle control and result in death or serious injury.
● Stop your vehicle in a safe place as soon as possible. Adjust the tire infla-
tion pressure immediately.
● Vehicles with spare tire: If the tire pressure warning light comes on even
after tire inflation pressure adjustment, it is probable that y ou have a flat
tire. Check the tires. If a tire is flat, change it with the sp are tire and have
the flat tire repaired by the nearest any authorized Toyota ret ailer or Toyota
authorized repairer, or any reliable repairer.
● Vehicles with emergency tire puncture repair kit: If the tire pressure warn-
ing light comes on even after ti re inflation pressure adjustment, it is proba-
ble that you have a flat tire. Check the tires. If a tire is fl at, repair the flat tire
by using emergency tire puncture repair kit. ( P. 697)
● Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you
could lose control of the steering wheel or the brakes.
■ If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.

When trouble arises
■If the tire is inflated to more than the specified air pressure
Press the button to let some air out.
Check that the air pressure indicator shows the specified air p ressure.
If the air pressure is under the designated pressure, turn the compressor
switch on (type A) or (on) (type B) again and repeat the inflation proce-
dure until the specified air pressure is reached.
■ The valve of a tire that has been repaired
After a tire is repaired with the emergency tire puncture repai r kit, the valve
should be replaced.
■ After a tire is repaired with the emergency tire puncture repair kit
● The tire pressure warning valve and transmitter should be replaced.
● Even if the tire inflation pressure is at the recommended level, the tire pres-
sure warning light may come on/flash.
■ Note for checking the emergency tire puncture repair kit
Check the sealant expiry date occasionally.
The expiry date is shown on the bottle. Do not use sealant whos e expiry date
has already passed. Otherwise, repairs conducted using the emer gency tire
puncture repair kit may not be performed properly.

■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.

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.

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.
