Clock
The time and date for the clock can be
set using the infotainment system. See
“Time/Date”in “System ”under
“Settings ”in the infotainment manual.
Power Outlets
The accessory power outlets can be
used to plug in electrical equipment,
such as a cell phone or MP3 player.
The vehicle has two accessory power
outlets:
.
Inside the center console
storage area.
. On the rear of the center floor
console.
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)
0163.
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.
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 0231.
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.
Always unplug electrical equipment
when not in use and do not plug in
equipment that exceeds the maximum
15 amps rating.

VEHICLE CARE 259
High Intensity Discharge
(HID) Lighting
{Warning
The High Intensity Discharge (HID)
lighting system operates at a very
high voltage. If you try to service
any of the system components, you
could be seriously injured. Have
your dealer or a qualified technician
service them.
After an HID headlamp bulb has been
replaced, the beam might be a slightly
different shade than it was originally.
This is normal.
LED Lighting
This vehicle has several LED lamps.
For replacement of any LED lighting
assembly, contact your dealer.
Front Turn Signal Lamps
Uplevel
See your dealer for turn signal
replacement.
Base level
To replace one of these lamps: 1. Open the hood.
2. Turn the bulb socket counterclockwise to remove it
from the headlamp assembly.
3. Unplug the electrical connector from the bulb by releasing the
clip on the connector.
4. Replace the bulb and reverse Steps 1–3 to reinstall.
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.
