Instruments and Controls 5-5
Power Outlets
The accessory power outlet can be
used to plug in electrical equipment,
such as a cell phone or MP3 player.
There are two 12-volt accessory
power outlets:
.On the center stack next to the
ashtray.
.Inside the center console.
The outlet is powered when the
ignition is in ON/RUN or ACC/
ACCESSORY, or until the driver
door is opened within 10 minutes of
turning off the vehicle. See Retained
Accessory Power (RAP) on
page 9-23.
Open the protective cover to use the
accessory power outlet.
Certain electrical accessories may
not be compatible with the
accessory power outlet and could
overload vehicle or adapter fuses.
If there is a problem, see your
dealer. When adding electrical equipment,
be sure to follow the installation
instructions included with the
equipment. See
Add-On Electrical
Equipment on page 9-65.
{Caution
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.
Power Outlet 110 Volt Alternating
Current
If equipped, this power outlet is on
the rear of the center console. It can
be used to plug in electrical
equipment with a maximum limit of
150 watts.
An indicator light on the outlet
comes on when in use. The light
comes on when the ignition is in
ON/RUN, equipment requiring less
than 150 watts is plugged into the
outlet, and no system fault is
detected.
The indicator light does not come on
when the ignition is in LOCK/OFF or
if the equipment is not fully seated
into the outlet.
If you try to connect equipment
using more than 150 watts or a
system fault is detected, the
equipment may operate for a short

period and turn itself off.
A protection circuit shuts off the
power supply and the indicator light
turns off. To reset the circuit, unplug
the item and plug it back in or turn
the Remote Accessory Power (RAP)
off and then back on. SeeRetained
Accessory Power (RAP) on
page 9-23. Prolonged usage of the
power outlet at the maximum load of
150 watts may cause the outlet to
overheat and automatically shut
down. The power restarts when
equipment that operates within the
limit is plugged into the outlet and a
system fault is not detected.
The power outlet is not designed for
the following equipment, and may
not work properly if any of the
following is plugged in:
.Equipment with high initial peak
wattage such as:
compressor-driven refrigerators
and electric power tools.
.Other equipment requiring an
extremely stable power supply
such as: microcomputer-controlled
electric blankets, touch sensor
lamps, etc.
.Medical equipment.
Cigarette Lighter
If equipped, push the lighter down
and it will pop up when it is ready to
be used. The ignition switch must
be in the ACC/ACCESSORY or ON/
RUN position to use the lighter.
{Caution
Holding a cigarette lighter in while
it is heating does not let the
lighter back away from the
heating element when it is hot.
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.
It is not recommended to use the
cigarette lighter to plug in auxiliary
electrical equipment.
Ashtrays
If equipped with an ashtray, it is
under the climate control system.
Press the ashtray cover to open. To
empty, grasp both sides of the
ashtray and remove.

6-4 Lighting
Turn and Lane-Change
Signals
Move the lever all the way up or
down to signal a turn.
An arrow on the instrument cluster
flashes in the direction of the turn or
lane change.Raise or lower the lever until the
arrow starts to flash to signal a lane
change. Hold it there until the lane
change is completed. If the lever is
briefly pressed and released, the
turn signal flashes three times.
The turn and lane-change signal
can be turned off manually by
moving the lever back to its original
position.
If after signaling a turn or lane
change the arrow flashes rapidly or
does not come on, a signal bulb
might be burned out.
Have any burned out bulbs
replaced. If the bulb is not burned
out, check the fuse. See
Fuses and
Circuit Breakers on page 10-35.
Fog Lamps
To turn on the fog lamps,
if equipped, the ignition and the
headlamps or parking lamps must
be on.
#(Fog Lamps, If Equipped):
Press to turn on or off. An indicator
light on the instrument cluster
comes on when the fog lamps
are on.
Some localities have laws that
require the headlamps to be on
along with the fog lamps.

Engine Oil
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.Always use engine oil approved
to the proper specification and of
the proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
.Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
.Change the engine oil at the
appropriate time. See Engine Oil
Life System on page 10-13.
.Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the oil
must be warm and the vehicle must
be on level ground. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview on
page 10-6 for the location of the
engine oil dipstick.
Obtaining an accurate oil level
reading is essential:
1. If the engine has been running recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.
