Power Outlets

Accessory power outlets can be

such as a cell phone or MP3 player.

outlets on the instrument panel, one
inside the center floor console, and
one on the rear of the center floor
console.
To access the accessory power
outlet inside the center floor
console, press the button on the

replace when not in use.
The accessory power outlets are

power outlets while the ignition is in
LOCK/OFF may cause the vehicle's
battery to run down.

Power is always supplied to the
outlets. Do not leave electrical
equipment plugged in when the
vehicle is not in use because the
vehicle could catch fire and cause
injury or death.
Leaving electrical
equipment plugged in for an
extended period of time while the

battery. Always unplug electrical
equipment when not in use and
do not plug in equipment that

Certain electrical accessories are
not compatible with the accessory
power outlets and could overload
vehicle or adapter fuses. If a
problem is experienced, see your
