●

If the replaced fuse blows again,

have the vehicle inspected by

your Toyota dealer.

■

If there is an overload in a cir-

cuit

The fuses are designed to blow, pro-

tecting the wiring harness from

damage.

■

When replacing light bulbs

Toyota recommends that you use

genuine Toyota products designed

for this vehicle.

Because certain bulbs are con-

nected to circuits designed to pre-

vent overload, non-genuine parts or

parts not designed for this vehicle

may be unusable.

WARNING

■

To prevent system break-

downs and vehicle fire

Observe the following precau-

tions.

Failure to do so may cause dam-

age to the vehicle, and possibly a

fire or injury.

●

Never use a fuse of a higher

amperage rating than that indi-

cated, or use any other object in

place of a fuse.

●

Always use a genuine Toyota

fuse or equivalent.

Never replace a fuse with a

wire, even as a temporary fix.

●

Do not modify the fuses or fuse

boxes.

NOTICE

■

Before replacing fuses

Have the cause of electrical over-

load determined and repaired by

your Toyota dealer as soon as

possible.

Light bulbs

You may replace the follow-
ing bulbs yourself. The diffi-
culty level of replacement
varies depending on the
bulb. If necessary bulb
replacement seems difficult
to perform, contact your
Toyota dealer.

For more information about
replacing other light bulbs,

LED light bulbs

sist of a number of LEDs. If any of

the LEDs burn out, take your vehicle

to your Toyota dealer to have the

light replaced.

■

Condensation build-up on the

inside of the lens

In certain situations, such as when

driving in the rain or when washing

the vehicle, condensation may form

on the inner side of the headlight

lens and other lights. As each light

has a ventilation hole, moist air may

enter. If the ambient temperature is

low, condensation may form tempo-

rarily, but it will dissipate as the

inside of the light is warmed up. As

the condensation is due to a phe-

nomenon similar to windows fogging

in the rain, it does not indicate a

malfunction.
Contact your Toyota dealer for more

information in the following situa-

tions:

●

Large drops of water have built up

on the inside of the lens.

●

Water has built up inside the

headlight.

WARNING

■

Replacing light bulbs

●

Turn off the lights. Do not

attempt to replace the bulb

immediately after turning off the

lights. The bulbs become very

hot and may cause burns.

●

Do not touch the glass portion

of the light bulb with bare

hands. When it is unavoidable

to hold the glass portion, use

and hold with a clean dry cloth

to avoid getting moisture and

oils on the bulb. Also, if the bulb

is scratched or dropped, it may

blow out or crack.

●

Fully install light bulbs and any

parts used to secure them. Fail-

ure to do so may result in heat

damage, fire, or water entering

the light unit. This may damage

the lights or cause condensa-

tion to build up on the lens.

■

To prevent damage or fire

Make sure bulbs are fully seated

and locked.

If your vehicle needs

to be towed

If towing is necessary, we
recommend having your
vehicle towed by your Toy-
ota dealer or commercial
towing service, using a
wheel-lift type truck or flat-
bed 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. (

tions.

Failure to do so may result in

death or serious injury.

■

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.

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.

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 dam-

age.

●

Do not turn the power switch off.

There is a possibility that the

steering wheel is locked and

cannot be operated.

■

Installing towing eyelets to

the vehicle

Make sure that towing eyelets are

installed securely.

If not securely installed, towing

eyelets may come loose during

towing.

NOTICE

■

To prevent damage to the

vehicle when towing using a

wheel-lift type truck

●

Vehicles without a smart key

system: Do not tow the vehicle

from the rear when the power

switch is off. The steering lock

mechanism is not strong

enough to hold the front wheels

straight.

●

Vehicles with a smart key sys-

tem: Do not tow the vehicle from

the rear when the power switch

is off.

●

When raising the vehicle,

ensure adequate ground clear-

ance for towing at the opposite

end of the raised vehicle. With-

out adequate clearance, the

vehicle could be damaged while

being towed.
