■To prevent injury
Before performing any light bulb
replacement procedure, be sure to turn
the power switch off. Failure to do so may
result in burns from hot components or a

■Replacing light bulbs
●Turn off the lights. Do not attempt to
replace the bulb immediately after

ble the light bulbs, connectors, electric
circuits or component parts.
Doing so may result in death or serious
injury due to electric shock.

towing, and abide by all state/pro-
vincial and local laws.

ure to do so may result in death or seri-
ous injury.

four wheels raised off the ground. If the
vehicle is towed with the tires contacting
the ground, the driv etrain or related
parts may be damaged, the vehicle may
fly off the truck, or electricity generated
by the operation of the motor may cause
a fire to occur depending on the nature
of the damage or malfunction.

avoid sudden starts, etc. which place
excessive stress on the towing eyelets,
cables or chains. The towing eyelets,
cables or chains may become dam-
aged, broken debris may hit people,
and cause serious damage.
