■When towing the vehicle

 2WD models

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 generated by the opera-

tion of the motor may cause a fire

to occur depending on the nature

of the damage or malfunction.

Use a towing dolly under the

rear wheels.

 From the rear

Use a towing dolly under the

front wheels.

WARNING

Observe the following precau-

tions. Failure to do so may result

in death or serious injury.

■Towing with a sling-type truck

WARNING

Do not tow with a sling-type truck

to prevent body damage.

 AWD models

Be sure to transport the vehicle

with all four wheels raised off the

ground. If the vehicle is towed

with the tires contacting the

ground, the drivetrain or related

parts may be damaged, the vehi-

cle may fly off the truck, or elec-

tricity generated by the operation

of the motor may cause a fire to

occur depending on the nature of

the damage or malfunction.

Using a flatbed truck

When using a flat-bed truck to

transport the vehicle, use tire

strapping belts. Refer to the

owner’s manual of the flat-bed

truck for the tire strapping

method.

In order to suppress vehicle

movement during transporta-

tion, set the parking brake and

turn the power switch off.

Emergency towing

If a tow truck is not available in

an emergency, your vehicle may

be temporarily towed using

cables or chains secured to the

emergency towing eyelets. This

should only be attempted on

hard surfaced roads for short

distances at under 18 mph (30

km/h).

NOTICE

■To prevent damage to the

vehicle when towing using a

wheel-lift type truck

When raising the vehicle, ensure

adequate ground clearance for

towing at the opposite end of the

raised vehicle. Without adequate

clearance, the vehicle could be

damaged while being towed.

A driver must be in the vehicle to

steer and operate the brakes.

The vehicle’s wheels, drive train,

axles, steering and brakes must

be in good condition.

WARNING

■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

eyelets, cables or chains may

become damaged, broken

debris may hit people, and

cause serious damage.

If you notice any of the fol-

lowing symptoms, your

vehicle probably needs

adjustment or repair. Con-

tact your Toyota dealer as

soon as possible.

●Do not perform any of the fol-

lowing as doing so may cause

the parking lock mechanism to

engage, locking the front

wheels and possibly leading to

an accident resulting in death or

serious injury:

Visible symptoms

■If a blowout or sudden air

leakage should occur

The tire pressure warning system

may not activate immediately.

Stop your vehicle in a safe place

immediately and contact your Toy-

ota dealer.

■Maintenance of the tires

The vehicle will become

extremely unstable during brak-

ing, and the ABS system may fail,

which could cause an accident

resulting in death or serious injury.

Each tire, including the spare (if

provided), should be checked

monthly when cold and inflated to

the inflation pressure recom-

mended by the vehicle manufac-

turer on the vehicle placard or tire

inflation pressure label (tire and

load information label). (If your

vehicle has tires of a different size

than the size indicated on the

vehicle placard or tire inflation

pressure label [tire and load infor-

mation label], you should deter-

mine the proper tire inflation

pressure for those tires.)

■When the electric power

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 inflation pressure immedi-

ately.

WARNING

equipped with a TPMS (tire pres-

sure warning system) malfunc-

tion indicator to indicate when the

system is not operating properly.

The TPMS (tire pressure warning

system) malfunction indicator is

combined with the low tire pres-

sure 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 con-

tinue upon subsequent vehicle

start-ups as long as the malfunc-

tion exists. When the malfunction

indicator is illuminated, the sys-

tem may not be able to detect or

signal low tire pressure as

As an added safety feature, your

vehicle has been equipped with a

tire pressure monitoring system

(TPMS-tire pressure warning sys-

tem) 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 pres-

sure warning light) illuminates,

you should stop and check your

tires as soon as possible, and

inflate them to the proper pres-

sure. 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 vehi-

cle’s handling and stopping ability.

intended.

TPMS (tire pressure warning sys-

tem) malfunctions may occur for a

variety 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 pressure

warning system) malfunction tell-

tale after replacing one or more

tires or wheels on your vehicle to

ensure that the replacement or

alternate tires and wheels allow

the TPMS (tire pressure warning

system) to continue to function

properly.

Please note that the TPMS (tire

pressure warning system) is not a

substitute for proper tire mainte-

nance, and it is the driver’s

responsibility to maintain correct

tire pressure, even if under-infla-

tion has not reached the level to

trigger illumination of the TPMS

low tire pressure telltale (tire pres-

sure warning light).

●Do not allow the other end of

the jumper cable connected to

the “+” terminal to come into

contact with any other parts or

metal surfaces in the area, such

as brackets or unpainted metal.

■When replacing the 12-volt bat-

tery

●Use a 12-volt battery that con-

forms to European regulations.

●Use a 12-volt battery that the case

size is same as the previous one

(LN1), 20 hour rate capacity

(20HR) is equivalent (45Ah) or

greater, and performance rating

(CCA) is equivalent (286A) or

greater.

• If the sizes differ, the 12-volt bat-

tery cannot be properly secured.

• If an improper 12-volt battery is

used, battery performance may

decrease and the EV system may

not be able to restart.

• If the 20 hour rate capacity is low,

even if the time period where the

vehicle is not used is a short time,

the 12-volt battery may discharge

and EV system may not be able to

start.

●Do not allow the + and - clamps

of the jumper cables to come

into contact with each other.

cigarette lighters or allow open

flame near the 12-volt battery.

■12-volt battery precautions

The 12-volt battery contains poi-

sonous and corrosive acidic elec-

trolyte, 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.

For details, consult your Toyota

dealer.

WARNING

●Do not lean over the 12-volt bat-

tery.

■When removing the 12-volt

battery terminals

●In the event that battery fluid

(acid) comes into contact with

the skin or eyes, immediately

wash the affected area with

water and seek medical atten-

tion.

Place a wet sponge or cloth

over the affected area until

medical attention can be

received.

Always remove the negative (-)

terminal first. If the positive (+) ter-

minal contacts any metal in the

surrounding area when the posi-

tive (+) terminal is removed, a

spark may occur, leading to a fire

in addition to electrical shocks

and death or serious injury.

■Avoiding 12-volt battery fires

or explosions

●Always wash your hands after

handling the 12-volt battery and

other battery-related parts.

Observe the following precautions

to prevent accidentally igniting the

flammable gas that may be emit-

ted from the 12-volt battery:

●Do not allow children near the

12-volt battery.

●Make sure each jumper cable is

connected to the correct termi-

nal and that it is not unintention-

ally in contact with any other

than the intended terminal.
