Power Inverter — If Equipped
There is a 230 Volt, 150 Watt inverter outlet
located on the back of the center console to
convert DC current to AC current.
This outlet can power cellular phones, elec-
tronics and other low power devices requiring
power up to 150 Watts. Certain high-end
video game consoles exceed this power limit,
as will most power tools.
Power Inverter
The power inverter is designed with built-in
overload protection. If the power rating of
150 Watts is exceeded, the power inverter
automatically shuts down. Once the elec -
trical device has been removed from the
outlet, the inverter should automatically
WARNING!
To avoid serious injury or death:
Do not insert any objects into the
receptacles.
Do not touch with wet hands.
Close the lid when not in use.
If this outlet is mishandled, it may cause
an electric shock and failure.
CAUTION!
Do not exceed the maximum power of
160 Watts (13 Amps) at 12 Volts. If the
160 Watt (13 Amp) power rating is
exceeded the fuse protecting the system
will need to be replaced.
Power outlets are designed for accessory
plugs only. Do not insert any other object
in the power outlets as this will damage
the outlet and blow the fuse. Improper
use of the power outlet can cause
damage not covered by your New Vehicle
Limited Warranty.
CAUTION!
Many accessories that can be plugged in
draw power from the vehicle's battery,
even when not in use (i.e., cellular
phones, etc.). Eventually, if plugged in
long enough, the vehicle's battery will
discharge sufficiently to degrade battery
life and/or prevent the engine from
starting.
Accessories that draw higher power (i.e.,
coolers, vacuum cleaners, lights, etc.),
will degrade the battery even more
quickly. Only use these intermittently
and with greater caution.
After the use of high power draw acces-
sories, or long periods of the vehicle not
being started (with accessories still
plugged in), the vehicle must be driven a
sufficient length of time to allow the
alternator to recharge the vehicle's
battery.
Power outlets are designed for accessory
plugs only. Do not hang any type of
accessory or accessory bracket from the
plug. Improper use of the power outlet
can cause damage.

1. Reach under the vehicle to access theback of the fog lamp.
2. Disconnect the wire harness connector from the fog lamp connector receptacle.
3. Rotate the socket a quarter turn counter -
clockwise, then remove it from the
housing.
4. Pull the bulb straight out from the keyed opening in the housing and then connect
the replacement bulb and reassemble.
FUSES
General Information
The fuses protect electrical systems against
excessive current.
When a device does not work, you must
check the fuse element inside the blade fuse
for a break/melt.
Also, please be aware that when using power
outlets for extended periods of time with the
engine off may result in vehicle battery
discharge.
CAUTION!
Do not touch the new bulb with your
fingers. Oil contamination will severely
shorten bulb life. If the bulb comes in
contact with any oily surface, clean the
bulb with rubbing alcohol.
WARNING!
When replacing a blown fuse, always use
an appropriate replacement fuse with
the same amp rating as the original fuse.
Never replace a fuse with another fuse of
higher amp rating. Never replace a blown
fuse with metal wires or any other mate-
rial. Failure to use proper fuses may
result in serious personal injury, fire and/
or property damage.
Before replacing a fuse, make sure that
the ignition is off and that all the other
services are switched off and/or disen -
gaged.
If the replaced fuse blows again, contact
an authorized dealer.
If a general protection fuse for safety
systems (air bag system, braking
system), power unit systems (engine
system, gearbox system) or steering
system blows, contact an authorized
dealer.
CAUTION!
If it is necessary to wash the engine
compartment, take care not to directly hit
the fuse box, and the windshield wiper
motors with water.
