Before performing any light bulb replacement procedure, be sure to turn the engine

switch off. Failure to do so may result in burns from hot components or a part of your

body may get caught on an operating component, possibly causing serious injury.

■

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 unavoid-

able 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. Failure to do so may result

in heat damage, fire, or water entering the headlight unit. This may damage the head-

lights or cause condensation to build up on the lens.

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.

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.

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.

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,
