Do not spill any liquid on the audio
system.
Do not insert any objects, other
than CDs, into the slot.
●To prevent the battery from being discharged, do not leave the audio system
on for a long period of time when the engine is not running.
● If a cellular phone or CB radio is used in or near the vehicle, it could cause
noise to occur from the audio system, however, this does not indicate that
the system has been damaged.
WARNING
■Always adjust the audio while the vehicle is stopped
Do not adjust the audio control switches while driving the vehicle. Adjusting
the audio while driving the vehicle is dangerous as it could distract your
attention from the vehicle operation which could lead to a serious accident.
Even if the audio control switches are equipped on the steering wheel, learn
to use the switches without looking down at them so that you can keep your
maximum attention on the road while driving the vehicle.
NOTICE
For the purposes of safe driving, adjust the audio volume to a level that
allows you to hear sounds outside of the vehicle including car horns and
particularly emergency vehicle sirens.
