equipment, such as a cell phone,
MP3 player, etc.
The vehicle may have two
accessory power outlets located
below the climate control system,
or may have one accessory power
outlet and one cigarette lighter.
The cigarette lighter is designed to
fit only in the receptacle closest to
the driver.
There may be another accessory
power outlet in the rear cargo area.
If the vehicle has a floor console,
there is an accessory power outlet
inside the storage bin and one on
the rear of the floor console.
Remove the cover to access and

The accessory power outlets are
powered, even when the ignition is
in LOCK/OFF. Continuing to use
power outlets while the ignition is in
LOCK/OFF may cause the vehicle's
battery to run down.
{WARNING
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.
Notice: Leaving electrical
equipment plugged in for an
extended period of time while
the vehicle is off will drain the
battery. Always unplug electrical
equipment when not in use and
do not plug in equipment that
exceeds the maximum 20 ampere
rating. Certain power accessory plugs may
not be compatible to the accessory
power outlet and could overload
vehicle or adapter fuses. If a
problem is experienced, see your
dealer.
When adding electrical equipment,
be sure to follow the proper
installation instructions included
with the equipment. See
Add-On
Electrical Equipment on page 9‑115.
Notice: Hanging heavy
equipment from the power
outlet can cause damage not
covered by the vehicle warranty.
The power outlets are designed
for accessory power plugs only,
such as cell phone charge cords.
Cigarette Lighter
To use the cigarette lighter,
push it in all the way, and let go.
When it is ready for use, the lighter
pops back out.
Notice: Holding a cigarette lighter
in while it is heating does not let

Damage from overheating can
occur to the lighter or heating
element, or a fuse could be
blown. Do not hold a cigarette
lighter in while it is heating.

The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on and a
chime sounds there could be a
brake problem. Have the brake
system inspected right away.
This light can also come on due to
low brake fluid. SeeBrake Fluid on
page 10‑30 for more information.

working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for

safely possible and turn the ignition
off. Then start the engine again to
reset the system. If the ABS light
