If your vehicle needs to be towed
The following may indicate a problem with your transmission. Contact
any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional or commercial towing service before towing.
● The hybrid system is operating but the vehicle does not move.
● The vehicle makes an abnormal sound.
Do not tow with a sling-type truck
to prevent body damage.
If towing is necessary, we recommend having your vehicle
towed by any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional or commercial towing
service, using a wheel-lift type truck or flatbed truck.
Use a safety chain system for all towing, and abide by all state/
provincial and local laws.
If towing your vehicle with a wheel-lift type truck from the front,
the vehicle’s rear wheels and axles must be in good conditions.
( P. 397, 401)
If they are damaged, use a towing dolly or flatbed truck.

■ If the tire pressure warning system is not functioning (vehicles with a
tire pressure warning system)
The tire pressure warning system will be disabled in the following conditions:
(When the condition becomes normal, the system will work properly.)
● If tires not equipped with tire pressure warning valves and transmitters are
used
● If the ID code on the tire pressure warning valves and transmitters is not
registered in the tire pressure warning computer
● If the tire inflation pressure is 500 kPa (5.1 kgf/cm2 or bar, 73 psi) or higher
The tire pressure warning system may be disabled in the following conditions:
(When the condition becomes normal, the system will work properly.)
● If electronic devices or facilities using similar radio wave frequencies are
nearby
● If a radio set at a similar frequency is in use in the vehicle
● If a window tint that affects the radio wave signals is installed
● If there is a lot of snow or ice on the vehicle, particularly around the wheels
or wheel housings
● If non-genuine Toyota wheels are used (Even if you use Toyota wheels, the
tire pressure warning system may not work properly with some types of
tires.)
● If tire chains are used
■ If the tire pressure warning light frequently comes on after blinking for 1
minute (vehicles with a tire pressure warning system)
If the tire pressure warning light frequently comes on after blinking for 1
minute when the power switch is turned on, have it checked by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped profes-

WARNING
■Driving to spread the liquid sealant evenly
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or
serious injury.
● Drive the vehicle carefully at a low speed. Be especially careful when turn-
ing and cornering.
● If the vehicle does not drive straight or you feel a pull through the steering
wheel, stop the vehicle and check the following.
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If the tire inflation pressure is 130 kPa (1.3 kgf/cm2
or bar, 19 psi) or less, the tire may be severely damaged.
NOTICE
■ When performing an emergency repair
● A tire should only be repaired with the emergency tire puncture repair kit if
the damage is caused by a sharp object such as nail or screw passing
through the tire tread.
Do not remove the sharp object from the tire. Removing the object may
widen the opening and disenable emergency repair with the repair kit.
● The repair kit is not waterproof. Make sure that the repair kit is not
exposed to water, such as when it is being used in the rain.
● Do not put the repair kit directly onto dusty ground such as sand at the
side of the road. If the repair kit vacuums up dust etc., a malfunction may
occur.

■ Precautions when the 12-volt battery is discharged
● In some cases, it may not be possible to unlock the doors using entry func-
tion of the smart entry & start system immediately after the 12-volt battery
has been disconnected and reconnected. Use the wireless remote control
or the mechanical key to lock or unlock the doors.
● The hybrid system may not start on the first attempt after the 12-volt battery
has recharged but will start normally after the second attempt. This is not a
malfunction.
● Vehicles with a smart entry & start system: The power switch mode is mem-
orized by the vehicle. When the 12-volt battery is reconnected, the system
will return to the mode it was in before the 12-volt battery was discharged.
Before disconnecting the 12-volt battery, turn the power switch off. If the
power switch was in ACCESSORY or ON mode before the 12-volt battery
was discharged, the audio system and/or air conditioning system may oper-
ate when the 12-volt battery is reconnected.
WARNING
■ Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting 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 anything other than the intended ter-
minal.
● 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.
■ After recharging the 12-volt battery
Have the 12-volt battery inspected at any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional 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 detrimental to the
health of passengers.

If your vehicle overheats
●The high engine coolant temperature warning light (P. 404)
comes on or flashes, or a loss of hybrid system power is experi-
enced. (For example, the vehicle speed does not increase.)
● If the hybrid system overheat warning light (P. 408) comes on.
● Steam comes out from under the hood.
■If the high engine coolant temperature warning light comes on
or flashes
Stop the vehicle in a safe place and turn off the air conditioning
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 the hoses and radia-
tor core (radiator) for any
leaks.
