■

Replacing light bulbs

●

Be sure to stop the hybrid system and 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.

●

Do not attempt to repair or disassemble light bulbs, connectors, electric circuits or

component parts.

Doing so may result in death or serious injury due to electric shock.

■

To prevent damage or fire 

●

Make sure bulbs are fully seated and locked. 

●

Check the wattage of the bulb before installing to prevent heat damage.

When towing the vehicle

■

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 turn the power switch off. 

This may lead to an accident as the front wheels will be locked by the parking lock.

■

Installing towing eyelet to the vehicle
Make sure that towing eyelet is installed securely.

If not securely installed, towing eyelet may come loose during towing.

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 oppo-

site end of the raised vehicle. Without adequate clearance, the vehicle could be dam-

aged 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.

■

To prevent damage to the vehicle during emergency towing
Do not secure cables or chains to the suspension components.

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 electric-

ity generated by the operation of the motor

may cause a fire to occur depending on the

nature of the damage or malfunction.
