■Sounds and vibrations caused by the ABS, brake assist, VSC, TRC and
hill-start assist control systems
Any of the following conditions may occur when the above systems are oper-
ating. None of these indicates that a malfunction has occurred.
●Vibrations may be felt through the vehicle body and steering.
●A motor sound may be heard after the vehicle comes to a stop.
●The brake pedal may pulsate slightly after the ABS is activated.
●The brake pedal may move down slightly after the ABS is activated.
■ECB operating sound
ECB operating sound may be heard in the following cases, but it does not
indicate that a malfunction has occurred.
●Operating sound heard from the engine compartment when the brake pedal
is operated.
●Motor sound of the brake system heard from the front part of the vehicle
when the driver’s door is opened.
●Operating sound heard from the engine compartment when 1-2 minutes
passed after the stop of the hybrid system.
■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the hybrid system
off. The EPS system should return to normal within 10 minutes.

When trouble arises
■While towing
If the hybrid system is off, the power assist for the brakes and steering will not
function, making steering and braking more difficult.
■ Wheel nut wrench
Wheel nut wrench is installed in luggage compartment. ( P. 479, 494)
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ When towing the vehicle
■ While towing
● When towing using cables or chains, avoid sudden starts, etc. which place
excessive stress on the towing eyelets, cables or chains. The towing eye-
lets, cables or chains may become damaged, broken debris may hit peo-
ple and cause serious damage.
● Do not turn the power switch off.
This may lead to an accident as the front wheels will be locked by the
parking lock.
■ Installing towing eyelets to the vehicle
● The towing eyelets are only for the vehicle equipped with them. Do not use
the towing eyelets for another vehicle, and do not use the towing eyelets
for this vehicle on another vehicle.
● Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing.
Be sure to transport the vehicle with the
front wheels raised or with all four wheels
raised off the ground. If the vehicle is
towed with the front wheels contacting
the ground, the drivetrain and related
parts may be damaged or electricity gen-
erated by the operation of the motor may
cause a fire to occur depending on the
nature of the damage or malfunction.

■Electric power steering system warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage tempo-
rarily drops, the electric power steering system warning light may come on
and the warning buzzer may sound.
■ If the malfunction indicator lamp comes on while driving
The malfunction indicator lamp will come on if the fuel tank becomes com-
pletely empty. If the fuel tank is empt y, refuel the vehicle immediately. The
malfunction indicator lamp will go off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized
Toyota retailer or Toyota authorized repai rer, or any reliable repairer as soon
as possible.
■ When the tire pressure warning light comes on
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: P. 478, 492
If the tire is not punctured:
Carry out the following procedure after the tire temperature has lowered suffi-
ciently.
● Check the tire inflation pressure and adjust to the appropriate level.
● If the warning light does not go out even after several minutes, check that
the tire inflation pressure is at the specified level and carry out initialization.
( P. 395)
The warning light may come on again if the above operations are conducted
without first allowing the tire temperature to lower sufficiently.
■ The tire pressure warning light may come on due to natural causes
The tire pressure warning light may turn on due to natural causes 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
The compact spare tire is not equipped with a tire pressure warning valve and
transmitter. If a tire goes flat, the tire pressure 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 adjus t the tire inflation pressure. The tire
pressure warning light will go off after a few minutes.

WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any authorized
Toyota retailer or Toyota authorized r epairer, 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 serious injury.
■ When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
When steering wheel operations are heavier than usual, grip the steering
wheel firmly and operate it using more force than usual.
■ 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 you have a flat
tire. Check the tires. If a tire is flat, change it with the spare tire and have
the flat tire repaired by the nearest any authorized Toyota retailer 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 tire inflat ion pressure adjustment, it is proba-
ble that you have a flat tire. Check the tire s. If a tire is flat, repair the flat tire
by using emergency tire puncture repair kit.
● 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.
NOTICE
■ To ensure the tire pressure warning system operates properly
Do not install tires with different specif ications or makers, as the tire pres-
sure warning system may not operate properly.
