AUXILIARY POWER POINT
Power outlets are designed for accessory plugs only. Do not insert
any other object in the power outlet as this can damage the
outlet and blow the fuse. Do not hang any type of accessory or
accessory bracket from the plug. Improper use of the power
outlet can cause damage not covered by your warranty.
Auxiliary power points can be found in the following locations:
•On the instrument panel (two locations)
•Inside the center console storage compartment (if equipped)
•On the rear of the center console (if equipped)
•Inside the 20-percent front seat console (if equipped)
•Inside the rear under seat storage compartment (if equipped)
Do not use the power point for operating the cigarette lighter element (if
equipped).
To prevent the fuse from being blown, do not use the power point(s)
over the vehicle capacity of 12 VDC/180W. If the power point or cigar
lighter socket is not working, a fuse may have blown. Refer toFuses and
relaysin theRoadside Emergencieschapter for information on
checking and replacing fuses.
To have full capacity usage of your power point, the engine is required to
be running to avoid unintentional discharge of the battery. To prevent
the battery from being discharged:
•do not use the power point longer than necessary when the engine is
not running,
•do not leave battery chargers, video game adapters, computers and
other devices plugged in overnight or when the vehicle is parked for
extended periods.
Always keep the power point caps closed when not being used.

For further information on the SYNCsystem, refer to theSYNC
supplement.
UPFITTER CONTROLS (IF EQUIPPED)
Your vehicle may be equipped with
the Upfitter option package which
provides four switches, mounted in
the center of the instrument panel,
labeled AUX 1, AUX 2, AUX 3 and
AUX 4. These switches only operate
while the ignition is in the on
position, whether the engine is
running or not. It is, however, recommended that the engine remain
running to maintain battery charge when using the Upfitter switches for
extended duration or higher current draws. (This is even more important
for vehicles with diesel engines since the glow plugs are also draining
battery power when the ignition key is in the on position.) Each switch
provides 10 amps of power.
If your vehicle is equipped with this option, there is also be a relay box
located on the driver side end of the instrument panel. See your
authorized dealer for service.
Switch access location is in a connector located in the engine
compartment More detailed information can be found at

BRAKE-SHIFT INTERLOCK
Vehicles equipped with a gasoline engine have a brake-shift interlock
feature that prevents the gearshift lever from being moved from P (Park)
when the ignition is in the on position and the brake pedal is not pressed.
If you cannot move the gearshift lever out of P (Park) with the ignition
in the on position and the brake pedal pressed, it is possible that a fuse
has blown or the vehicle’s brake lamps are not operating properly. Refer
toFuses and relaysin theRoadside Emergencieschapter.
If the fuse is not blown and the brake lamps are working properly, the
following procedure will allow you to move the gearshift lever from P (Park):
1. Apply the parking brake, and turn
the engine off.
2. Remove the lower finish panel
below the steering column
3. Turn the key to on (position 4),
but do not start engine.
4. Pull back on the solenoid, and at
the same time, shift the
transmission into N (Neutral).
5. Start the vehicle.
See your authorized dealer as
soon as possible if this
procedure is used.
WARNING:Do not drive
your vehicle until you verify
that the brake lamps are working.
