7-24 Infotainment System
Moving too far forward or stepping
out of the vehicle can cause the
headphones to lose the signal or
have static.
To adjust the volume on the
headphones, use the volume
control.
For optimal audio performance, the
headphones must be worn correctly.
Headphones should be worn with
the headband over the top of the
head for best audio reception.
The symbol L (Left) appears on the
outside bottom edge of the ear cup
and should be positioned on the left
ear. The symbol R (Right) appears
on the outside bottom edge of the
ear cup and should be positioned
on the right ear.
Do not store the
headphones in heat or direct
sunlight. This could damage
the headphones and repairs will
not be covered by the warranty.
Storage in extreme cold can
weaken the batteries. Keep the
headphones stored in a cool,
dry place.
If the foam ear pads attached to
the headphones become worn or
damaged, the pads can be replaced
separately from the headphone set.
To purchase replacement ear pads,
call 1 888 293 3332, then prompt
zero (0), or contact your dealer.

3. Replace the two AAA batteries.
