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.

●

Do not attempt to repair or dis-

assemble light bulbs, connec-

tors, 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.

When towing the vehicle



2WD 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 and related 
parts may be damaged, an acci-
dent may occur due to a change 
in direction of the vehicle 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.



4WD 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
