These outlets are powered while the
vehicle is in ON/RUN/START or
ACC/ACCESSORY mode, or until
the driver door is opened within
10 minutes of turning off the vehicle.
Lift the cover to access the
accessory power outlet.
Certain electrical accessories may
not be compatible with the
accessory power outlet and could
overload a vehicle circuit breaker or
adapter fuse. If overloaded, the
circuit breaker will reset after all
devices are disconnected or if
Retained Accessory Power (RAP) is
turned off and then back on. See
Retained Accessory Power (RAP)
on page 9-19
. Wait one minute to
allow the circuit breaker to reset
before reconnecting devices or
turning RAP back on. If the problem
continues, the issue could be within
your device. Try another known
good device to make sure the circuit
breaker is operating properly. If this
does not resolve your problem, see
your dealer.
It is possible to replace the factory
power outlet with a cigar lighter
receptacle, if desired. This requires
the factory installed circuit breaker
to be replaced with a standard
minifuse by the dealer. A minifuse
will not reset and will have to be
replace if blown.
{
Caution
Failure to replace the circuit
breaker with the minifuse could
overheat the cigar lighter and
damage the vehicle.
When adding electrical equipment,
be sure to follow the proper
installation instructions included with
the equipment. See
Add-On
Electrical Equipment on page 9-70
.
{
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
inside the center console. It can be
used to plug in electrical equipment
that uses a maximum limit of 150
watts.

Lighting
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.
Replace any burned out bulbs. If a
bulb is not burned out, check the
fuse. See
Fuses and Circuit
Breakers on page 10-32

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 10-12
.
.
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 10-5
for the location of the
engine oil dipstick.
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
10-25
What to Add
Use only new DOT 3 brake fluid
from a sealed container. See
Recommended Fluids and
Lubricants on page 11-13
.
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it. This
helps keep dirt from entering the
reservoir.
{
Warning
With the wrong kind of fluid in the
brake hydraulic system, the
brakes might not work well. This
could cause a crash. Always use
the proper brake fluid.
{
Caution
.
Using the wrong fluid can
badly damage brake
hydraulic system parts. For
(Continued)
Caution (Continued)
example, just a few drops of
mineral-based oil, such as
engine oil, in the brake
hydraulic system can damage
brake hydraulic system parts
so badly that they will have to
be replaced. Do not let
someone put in the wrong
kind of fluid.
.
If brake fluid is spilled on the
vehicle's painted surfaces,
the paint finish can be
damaged. Be careful not to
spill brake fluid on the
vehicle. If you do, wash it off
immediately.
Battery
The battery is in the trunk, behind
the trim panel, on the driver side of
the vehicle. Refer to the
replacement number shown on the
original battery label when a new
battery is needed.
{
Warning
Battery posts, terminals, and
related accessories contain lead
and lead compounds, chemicals
known to the State of California to
cause cancer and reproductive
harm. Wash hands after handling.
After a power loss, such as
disconnecting the battery or
removing the maxi fuses in the
power distribution fuse block, the
following steps must be performed
to calibrate the electronic throttle
control. If this is not done, the
engine will not run properly.
1.
Turn the ignition on but do not
start the engine.
2.
Leave the ignition on for at least
three minutes so that the
electronic throttle control will
cycle and relearn its home
position.
3.
Turn the ignition off.

Electrical System
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. Wiper function is
available immediately after the wiper
switch is set to off, and back to on.
To protect the wiper motor from
overheating, the wipers may slow
down when the windshield is dry for
a long period of time. If a period of
dry operation, or little moisture,
exceeds ten minutes, the wipers
may switch to intermittent operation,
and remain there. When moisture is
again detected on the windshield,
wiper operation will return to the
operator selected speed.
10-32
Vehicle Care
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

Block on page 10-35
