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.

■

Replacing light bulbs

●

Turn off the lights. Do not

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.

WARNING

Observe the following precau-

tions.

Failure to do so may result in

death or serious injury.

■

When towing the vehicle

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.

■

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 engine 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

●

Do not tow the vehicle from the

rear when the engine 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.

■

To prevent damage to the

vehicle when towing with a

sling-type truck

Do not tow with a sling-type truck,

either from the front or rear.
