Power Outlets
The accessory power outlets can be
used to plug in electrical equipment,
such as a cell phone or MP3 player.
There are two accessory power
outlets: one under the armrest
inside the center console storage,
and one on the rear of the center
floor 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 9-68
.
{
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
The vehicle may have a power
outlet that can be used to plug in
electrical equipment with a
maximum limit of 150 watts.
The power outlet is on the rear of
the center console.

Hazard Warning Flashers
|
(Hazard Warning Flashers):
Press this button on the center
stack above the audio system, to
make the front and rear turn signal
lamps flash on and off. Press again
to turn the flashers off.
The hazard warning flashers turn on
automatically if the airbags deploy.
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
If equipped with fog lamps, the
button is on the exterior lamp
control, left of the steering wheel.

Driving and Operating
.
Auto stop time is greater than
two minutes.
.
The hood is opened.
Engine Heater
The engine coolant heater,
if available, can help in cold weather
conditions at or below
18°C (0°F)
for easier starting and better fuel
economy during engine warm-up.
Plug in the coolant heater at least
four hours before starting the
vehicle. An internal thermostat in
the plug end of the cord will prevent
engine coolant heater operation at
temperatures above
18°C (0°F).
To Use the Engine Coolant
Heater
1.
Turn off the engine.
2.
Open the hood and unwrap the
electrical cord.
3.6L V6 Engine
The electrical cord is located on
the driver side of the engine
compartment, between the
fender and the engine
compartment fuse block on
vehicles with a six cylinder
engine.
2.4L L4 Engine
The electrical cord is located on
the passenger side of the engine
compartment, between the
fender and the air cleaner on
vehicles with a four cylinder
engine.
Check the heater cord for
damage. If it is damaged, do not
use it. See your dealer for a
replacement. Inspect the cord for
damage yearly.
3.
Plug it into a normal, grounded
110-volt AC outlet.

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 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.
{
Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
Vehicle Care
10-35
Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load is
too heavy, the circuit breaker opens
and closes, protecting the circuit
until the current load returns to
normal or the problem is fixed. This
greatly reduces the chance of circuit
overload and fire caused by
electrical problems.
Fuses and circuit breakers protect
power devices in the vehicle.
Replace a bad fuse with a new one
of the identical size and rating.
If there is a problem on the road and
a fuse needs to be replaced, the
same amperage fuse can be
borrowed. Choose some feature of
the vehicle that is not needed to use
and replace it as soon as possible.
Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have the
headlamp wiring checked right away
if the lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.
Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice may
cause wiper linkage damage.
Always clear ice and heavy snow
from the windshield before using the
windshield wipers.
If the overload is caused by an
electrical problem and not snow or
ice, be sure to get it fixed.
Fuses and Circuit
Breakers
The wiring circuits in the vehicle are
protected from short circuits by a
combination of fuses and circuit
breakers. This greatly reduces the
chance of damage caused by
electrical problems.
To check a fuse, look at the
silver-colored band inside the fuse.
If the band is broken or melted,
replace the fuse. Be sure to replace
a bad fuse with a new one of the
identical size and rating.
Fuses of the same amperage can
be temporarily borrowed from
another fuse location, if a fuse goes
out. Replace the fuse as soon as
possible.
To identify and check fuses, circuit
breakers, and relays, see
Engine
Compartment Fuse Block on
page 10-36
and
Instrument Panel
Fuse Block on page 10-40
