Battery precautions

Observe the following precau-

tions.
Failure to do so may result in

death or serious injury.

●

Do not swallow the battery.

Doing so may cause chemical

burns.

●

A coin battery or button battery

is used in the electronic key. If a

battery is swallowed, it may

cause severe chemical burns in

as little as 2 hours and may

result in death or serious injury.

●

Keep away new and removed

batteries from children.

●

If the cover cannot be firmly

closed, stop using the electronic

key and stow the key in the

place where children cannot

reach, and then contact your

Toyota dealer.

●

If you accidentally swallow a

battery or put a battery into a

part of your body, get emer-

gency medical attention imme-

diately.

■

To prevent battery explosion

or leakage of flammable liq-

uid or gas

●

Replace the battery with a new

battery of the same type. If a

wrong type of battery is used, it

may explode.

●

Do not expose batteries to

extremely low pressure due to

high altitude or extremely high

temperatures.

●

Do not burn, break or cut a bat-

tery.

NOTICE

■

When replacing the battery

Use a flathead screwdriver of

appropriate size. Applying exces-

sive force may deform or damage

the cover.

■

For normal operation after

replacing the battery

Observe the following precautions

to prevent accidents:

●

Always work with dry hands.

Moisture may cause the battery

to rust.

●

Do not touch or move any other

component inside the remote

control.

●

Do not bend either of the battery

terminals.

The fuses are designed to blow, pro-

tecting the wiring harness from

damage.

■

When replacing an electronic

component, such as a lights,

etc.

Toyota recommends that you use

genuine Toyota products designed

for this vehicle. Because certain

bulbs are connected to circuits

designed to prevent 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.

If the door can be opened,
open the door and exit the
vehicle.



If the door can not be opened,
open the window using the
power window switch and
ensure an escape route.



If the window can be opened,
exit the vehicle through the
window.



If the door and window cannot
be opened due to the rising
water, remain calm, wait until
the water level inside the
vehicle rises to the point that
the water pressure inside of
the vehicle equals the water
pressure outside of the vehi-
cle and then open the door
after waiting for the rising
water to enter the vehicle, and
exit the vehicle. When the

outside water level exceeds
half the height of the door, the
door cannot be opened from
the inside due to water pres-
sure.

■

Water level exceeds the floor

When the water level exceeds the

floor and time has passed, the elec-

trical equipment will get damaged,

the power windows will not operate,

the motor stop, and the vehicle may

not be able to get moving.

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.

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.

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).
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



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.

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.

Insert the towing eyelet into
the hole and tighten partially
by hand.

Tighten down the towing eye-
let securely using a wheel

bolt wrench or hard metal
bar.

Securely attach cables or
chains to the towing eyelet.

Take care not to damage the vehi-

cle body.

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.

●

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:

• Unfasten the driver’s seat belt

and open the driver’s door.

• Turn the power switch off.

■

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 during emergency

towing

Do not secure cables or chains to

the suspension components.

If you think something

is wrong

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.
