If your vehicle needs to be tow ed  
If towing is necessary, we recommend having your vehicle towed by  
your Toyota dealer or a commercial towing service, using a lift-type  
truck or flat bed truck.  
Use a safety chain system for all towing, and abide by all state/pro-  
vincial and local laws.  
Before towing  
The following may indicate a problem with your hybrid transmission.  
Contact your Toyota dealer before towing.  
● The hybrid system is operating but the vehicle will not move.  
● The vehicle makes an abnormal sound.  
If there is a malfunction in the P position control system, the smart  
key system or the immobilizer system, or if the 12-volt battery is dis-  
charged, the vehicle cannot be towed with the front wheels on the  
ground, as the front wheels may be locked. In this case, transport the  
vehicle with both front wheels or all four wheels lifted.

5-2. Steps to take in an emergency  
■Electric power steering system warning light  
When the 12-volt battery charge becomes insufficient or the voltage tempo-  
rarily drops, the electric power steering system warning light may come on.  
■If the malfunction indicator lamp comes on while driving  
First check the following:  
●Is the fuel tank cap loose?  
If it is, tighten it securely.  
The malfunction indicator lamp will go off after several driving trips.  
If the malfunction indicator lamp does not go off even after several trips, con-  
tact your Toyota dealer as soon as possible.  
■When the tire pressure warning light comes on  
Check the tire inflation pressure and adjust to the appropriate level.  
Pushing the tire pressure warning reset switch will not turn off the tire  
pressure warning light.  
■The tire pressure warning light may come on due to natural causes  
The tire pressure warning light may come on due to natural causes such  
as natural air leaks and tire inflation pressure changes caused by tem-  
perature. 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  
5
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 adjust the tire infla-  
tion pressure. The tire pressure warning light will go off after a few min-  
utes.

5-2. Steps to take in an emergency  
■If the tire pressure warning system is not functioning  
The tire pressure warning system will be disabled in the following condi-  
tions:  
(When the condition becomes normal, the system will work properly.)  
●If tires not equipped with tire pressure warning valves and transmit-  
ters are used  
●If the ID code on the tire pressure warning valves and transmitters is  
not registered in the tire pressure warning computer  
2
●If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm or bar) or  
higher  
The tire pressure warning system may be disabled in the following condi-  
tions:  
(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  
502  
5-2. Steps to take in an emergency  
■If the tire pressure warning light frequently comes on after blinking  
for 1 minute  
If the tire pressure warning light frequently comes on after blinking for 1  
minute when the “POWER” switch is turned to ON mode, have it  
checked by your Toyota dealer.  
■Customization  
The vehicle speed linked seat belt reminder buzzer can be disabled.  
(Customizable features P. 590) However, Toyota recommends that the  
seat belt reminder buzzer be operational to alert the driver and front passen-  
ger when seat belts are not fastened.  
CAUTION  
■If both the ABS and the brake system warning lights remain on  
Stop your vehicle in a safe place immediately and contact your Toyota  
dealer. 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.  
If the steering wheel becomes heavier than usual when operating, hold  
firmly and operate using more force than usual.

5-2. Steps to take in an emergency  
CAUTION  
■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  
inflation pressure immediately.  
●If the tire pressure warning light comes on even after tire inflation pres-  
sure 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 Toyota dealer.  
●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.  
■Maintenance of the tires  
Each tire, including the spare (if provided), should be checked monthly  
when cold and inflated to the inflation pressure recommended by the  
vehicle manufacturer on the vehicle placard or tire inflation pressure  
label (tire and load information label). (If your vehicle has tires of a differ-  
ent size than the size indicated on the vehicle placard or tire inflation  
pressure label [tire and load information label], you should determine the  
proper tire inflation pressure for those tires.)  
504  
5-2. Steps to take in an emergency  
CAUTION  
As an added safety feature, your vehicle has been equipped with a tire  
pressure monitoring system (TPMS-tire pressure warning system) that  
illuminates a low tire pressure telltale (tire pressure warning light) when  
one or more of your tires is significantly under-inflated. Accordingly,  
when the low tire pressure telltale (tire pressure warning light) illumi-  
nates, you should stop and check your tires as soon as possible, and  
inflate them to the proper pressure. Driving on a significantly under-  
inflated tire causes the tire to overheat and can lead to tire failure.  
Under-inflation also reduces fuel efficiency and tire tread life, and may  
affect the vehicle’s handling and stopping ability.  
Please note that the TPMS (tire pressure warning system) is not a sub-  
stitute for proper tire maintenance, and it is the driver’s responsibility to  
maintain correct tire pressure, even if under-inflation has not reached the  
level to trigger illumination of the TPMS low tire pressure telltale (tire  
pressure warning light).  
Your vehicle has also been equipped with a TPMS (tire pressure warning  
system) malfunction indicator to indicate when the system is not operat-  
ing properly. The TPMS (tire pressure warning system) malfunction indi-  
cator is combined with the low tire pressure telltale (tire pressure  
warning light). When the system detects a malfunction, the telltale will  
flash for approximately one minute and then remain continuously illumi-  
nated. This sequence will continue upon subsequent vehicle start-ups as  
long as the malfunction exists. When the malfunction indicator is illumi-  
nated, the system may not be able to detect or signal low tire pressure  
as intended.  
5
505  
5-2. Steps to take in an emergency  
CAUTION  
TPMS (tire pressure warning system) malfunctions may occur for a vari-  
ety of reasons, including the installation of replacement or alternate tires  
or wheels on the vehicle that prevent the TPMS (tire pressure warning  
system) from functioning properly. Always check the TPMS (tire pres-  
sure warning system) malfunction telltale after replacing one or more  
tires or wheels on your vehicle to ensure that the replacement or alter-  
nate tires and wheels allow the TPMS (tire pressure warning system) to  
continue to function properly.  
NOTICE  
■Precaution when installing a different tire  
When a tire of a different specification or maker is installed, the tire pres-  
sure warning system may not operate properly.

5-2. Steps to take in an emergency  
CAUTION  
■Replacing a flat tire  
●Do not touch the disc wheels or the area around the brakes immedi-  
ately after the vehicle has been driven.  
After the vehicle has been driven the disc wheels and the area around  
the brakes will be extremely hot. Touching these areas with hands, feet  
or other body parts while changing a tire, etc. may result in burns.  
●Failure to follow these precautions could cause the wheel nuts to  
loosen and the tire to fall off, resulting in death or serious injury.  
• Have the wheel nuts tightened with a torque wrench to 76 ft•lbf (103  
N•m, 10.5 kgf•m) as soon as possible after changing wheels.  
• When installing a tire, only use wheel nuts that have been specifically  
designed for that wheel.  
• If there are any cracks or deformations in the bolt screws, nut threads  
or bolt holes of the wheel, have the vehicle inspected by your Toyota  
dealer.  
• When installing the wheel nuts, be sure to install the wheel nuts with  
the tapered end facing inward. (P. 452)  
■After using the tools and jack  
Before driving, make sure all the tools and jack are securely in place in  
their storage location to reduce the possibility of personal injury during a  
collision or sudden braking.  
■When stowing the flat tire  
●Make sure the rear seatbacks are in their original position.  
●Secure it using a tire tie-down belt. Otherwise, the flat tire may fly out  
in case of sudden braking or an accident, resulting in death or serious  
injury.

wheels are locked by the parking lock. (P. 485)  
●When the 12-volt battery is reconnected, start the hybrid system, depress  
the brake pedal, and confirm that it is possible to shift into each shift posi-  
tion.  
■Charging the 12-volt battery  
The electricity stored in the 12-volt battery will discharge gradually even  
when the vehicle is not in use, due to natural discharge and the draining  
effects of certain electrical appliances. If the vehicle is left for a long time, the  
12-volt battery may discharge, and the hybrid system may be unable to start.  
(The 12-volt battery recharges automatically while the hybrid system is oper-  
ating.)

■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 any other than the intended 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 electrolyte,  
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 battery fluids (acid) to come into contact with  
skin, clothing or the vehicle body.

CAUTION  
■After recharging the 12-volt battery  
Have the 12-volt battery inspected at your Toyota dealer as soon as possi-  
ble.  
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.  
■When replacing the 12-volt battery  
P. 435  
NOTICE  
■When handling jumper cables  
When connecting the jumper cables, ensure that they do not become entan-  
gled in the cooling fans, etc.  
■Exclusive jump starting terminal  
The exclusive jump starting terminal is to be used when charging the 12-volt  
battery from another vehicle in an emergency. It cannot be used to jump start  
another vehicle.

5-2. Steps to take in an emergency  
CAUTION  
■To prevent an accident or injury when inspecting under the hood of  
your vehicle  
●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, caus-  
ing serious injuries such as burns.  
●Check that the indicator on the “POWER” switch and the “READY” indica-  
tor are off.  
●For vehicles with a hybrid system, there are times when the gasoline  
engine automatically starts to run or the cooling fans suddenly start to  
operate. Do not touch or approach the rotating parts of the fans, etc. Doing  
so may lead to fingers, clothes or tools getting caught, resulting in injury.  
●Do not loosen the coolant reservoir cap while the hybrid system and radia-  
tor are hot.  
Serious injury, such as burns, may result from hot coolant and steam  
released under pressure.  
NOTICE  
■When adding engine/power control unit coolant  
5
Wait until the hybrid system has cooled down before adding engine/power  
control unit coolant.  
When adding coolant, do so slowly. Adding cool coolant to a hot hybrid sys-  
tem too quickly can cause 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 commercially available coolant additives
