114 INSTRUMENTS AND CONTROLS
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)0197.
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 0251.
Caution
Adding any electrical equipment to
the vehicle may damage it or keep
other components from working as
they should. The repairs would not
be covered by the vehicle warranty.
Do not use equipment exceeding
maximum amperage rating of
15 amperes. Check with your dealer
before adding electrical equipment.
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 110/120 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.

starting the vehicle; driving a short
distance is required to calibrate the
AFL. SeeExterior Lamp Controls 0153.
Hazard Warning Flashers
|:Press and hold this button for
one second to make the front and rear
turn signal lamps flash on and off.
Release the button for at least
one second and 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.
Replace any burned out bulbs. If a
bulb is not burned out, check the fuse.

Fuses and Circuit Breakers 0285.

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:
.
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 0265.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
Check the engine oil level regularly,
every 650 km (400 mi), especially prior
to a long trip. The engine oil dipstick handle is a loop. See
Engine
Compartment Overview 0256 for the
location.
{Warning
The engine oil dipstick handle may
be hot; it could burn you. Use a
towel or glove to touch the dipstick
handle.
If a low oil Driver Information Center
(DIC) message displays, check the oil
level.
Follow these guidelines:
. To get an accurate reading, park
the vehicle on level ground. Check
the engine oil level after the
engine has been off for at least
two hours. Checking the engine oil
level on steep grades or too soon
after engine shutoff can result in
incorrect readings. Accuracy
improves when checking a cold
engine prior to starting. Remove
the dipstick and check the level.
