68GETTING TO KNOW YOUR VEHICLE
(Continued)
NOTE:Plugging in a phone or another USB device may
cause the connection to a previous device to be
lost.
For further information, refer to the Uconnect
Owner’s Manual Supplement or visit
UconnectPhone.com.
ELECTRICAL POWER OUTLETS
The auxiliary 12 Volt (13 Amp) power outlet can
provide power for in-cab accessories designed for
use with the standard “cigarette lighter” style plug.
The 12 Volt power outlets and 5 Volt (2.5 Amp) USB
port (Charge Only) have a cap attached to the
outlet indicating “12V DC”, together with either a
key symbol, battery symbol, or USB symbol.
A key symbol indicates that the ignition must be in
the ON/RUN or ACC positions for the outlet to
provide power. The battery symbol indicates that
the outlet is connected to the battery, and can
provide power at all times. An auxiliary power outlet can be found in the tray
on top of the center stack. This power outlet works
when the ignition is in the ON/RUN, ACC, or OFF
position.

Power Outlet — Top Of Center Stack
Power Outlet Fuse Locations:
F104 Fuse 20 A Yellow UCI Port/ USB Rear
Center Console
F90 Fuse 20 A Yellow Instrument Panel Power
Outlet Battery Fed (If Equipped)
F91 Fuse 20 A Yellow Instrument Panel Power
Outlet Ignition Fed (If Equipped)
F93 Fuse 20 A Yellow Cigar Lighter/ Instrument
Panel Power Outlet (If Equipped)
When the vehicle is turned off, be sure to unplug
any equipment as to not drain the battery of the
vehicle. All accessories connected to the outlet(s)
should be removed or turned off when the vehicle
is not in use to protect the battery against
discharge.
CAUTION!

Do not exceed the maximum power of 160 Watts

(13 Amps) at 12 Volts. If the 160 Watts
(13 Amps) power rating is exceeded, the fuse
protecting the system will need to be replaced.
Power outlets are designed for accessory
plugs only. Do not insert any other object in
the power outlets as this will damage the
outlet and blow the fuse. Improper use of the
power outlet can cause damage not covered
by your New Vehicle Limited Warranty.
CAUTION!
WARNING!
To avoid serious injury or death:
Only devices designed for use in this type of
outlet should be inserted into any 12 Volt
outlet.
Do not touch with wet hands.
Close the lid when not in use and while driving
the vehicle.
If this outlet is mishandled, it may cause an
electric shock and failure.

320IN CASE OF EMERGENCY
PREPARATIONS FOR JUMP START
The battery in your vehicle is located in the front of
the engine compartment, behind the left headlight
assembly.

Battery Location

If you have a diesel engine, you may have two
batteries, however jump start off the driver side
battery.
The positive battery post may be covered with a
protective cap if equipped. Lift up on the cap to
gain access to the positive battery post. Do not
jump off fuses. Only jump directly off positive post
which has a positive (+) symbol on or around the
post.
NOTE:

1. Apply the parking brake, shift the automatic transmission into PARK and turn the ignition
OFF.

2. Turn off the heater, radio, and all electrical accessories.
3. If using another vehicle to jump start the battery, park the vehicle within the jumper
cables reach, apply the parking brake, and
make sure the ignition is OFF.
JUMP STARTING PROCEDURE
NOTE:Make sure at all times that unused ends of jumper
cables are not contacting each other or either
vehicle while making connections.
WARNING!
Take care to avoid the radiator cooling fan
whenever the hood is raised. It can start
anytime the ignition switch is ON. You can be
injured by moving fan blades.
Remove any metal jewelry such as rings,
watch bands and bracelets that could make
an inadvertent electrical contact. You could be
seriously injured.
Batteries contain sulfuric acid that can burn
your skin or eyes and generate hydrogen gas
which is flammable and explosive. Keep open
flames or sparks away from the battery.
WARNING!
Do not allow vehicles to touch each other as this
could establish a ground connection and
personal injury could result.
WARNING!
Failure to follow this jump starting procedure
could result in personal injury or property
damage due to battery explosion.
CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster
vehicle or the discharged vehicle.

22_DPF_OM_EN_USC_t.book Page 320

IN CASE OF EMERGENCY321
Connecting The Jumper Cables

1. Connect the positive
(+) end of the jumper
cable to the positive (+)
post of the discharged
vehicle.

NOTE:Do not jump off fuses. Only jump directly off
positive post.
2. Connect the opposite end of the positive (+)
jumper cable to the positive (+) post of the
booster battery.
3. Connect the negative (-) end of the jumper
cable to the negative (-) post of the booster
battery.
4. Connect the opposite end of the negative (-)
jumper cable to a good engine ground. A
“ground” is an exposed metallic/unpainted
part of the engine, frame or chassis, such as
an accessory bracket or large bolt. The ground
must be away from the battery and fuel
injection system.
Jump Starting Label

5. Start the engine in the vehicle that has the booster battery, let the engine idle a few
minutes, and then start the engine in the
vehicle with the discharged battery. 6. Once the engine is started, follow the discon
-
necting procedure below.
Disconnecting The Jumper Cables

1. Disconnect the negative
(-)
end of the jumper
cable from the engine ground of the vehicle
with the discharged battery.

2. Disconnect the opposite end of the negative (-)
jumper cable from the negative (-) post of the
booster battery.
3. Disconnect the positive (+) end of the jumper
cable from the positive (+) post of the booster
battery.
4. Disconnect the opposite end of the positive (+)
jumper cable from the positive (+) post of the
vehicle with the discharged battery.
If frequent jump starting is required to start your
vehicle you should have the battery and charging
system inspected at an authorized dealer.
WARNING!
Do not connect the jumper cable to the
negative (-) post of the discharged battery. The
resulting electrical spark could cause the battery
to explode and could result in personal injury.
CAUTION!
Do not connect jumper cable to any of the fuses
on the positive battery terminal. The resulting
electrical current will blow the fuse.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular devices, etc.).
Eventually, if plugged in long enough without
engine operation, the vehicle’s battery will
discharge sufficiently to degrade battery life
and/or prevent the engine from starting.

364SERVICING AND MAINTENANCE
FUSES
General Information
The fuses protect electrical systems against
excessive current.
When a device does not work, you must check the
fuse element inside the blade fuse for a break/
melt.
Also, please be aware that using power outlets for
extended periods of time with the engine off may
result in vehicle battery discharge.

Blade Fuses
Power Distribution Center
The Power Distribution Center is located in the
engine compartment near the battery. This center
contains cartridge fuses, micro fuses, relays, and
circuit breakers. A description of each fuse and
component may be stamped on the inside cover,
otherwise the cavity number of each fuse is
stamped on the inside cover that corresponds to
the following chart.
WARNING!
When replacing a blown fuse, always use an
appropriate replacement fuse with the same
amp rating as the original fuse. Never replace
a fuse with another fuse of higher amp rating.
The use of a fuse with a rating other than indi -
cated may result in a dangerous electrical
system overload. If a properly rated fuse
continues to blow, it indicates a problem in the
circuit that must be corrected. Never replace a
blown fuse with metal wires or any other mate -
rial. Do not place a fuse inside a circuit
breaker cavity or vice versa. Failure to use
proper fuses may result in serious personal
injury, fire and/or property damage.
Before replacing a fuse, make sure that the
ignition is off and that all the other services
are switched off and/or disengaged.
If the replaced fuse blows again, contact an
authorized dealer.
If a general protection fuse for safety systems
(air bag system, braking system), power unit
systems (engine system, transmission
system) or steering system blows, contact an
authorized dealer.

CAUTION!
When installing the power distribution center
cover, it is important to ensure the cover is
properly positioned and fully latched. Failure to
do so may allow water to get into the power
distribution center and possibly result in an
electrical system failure.
CAUTION!
If it is necessary to wash the engine
compartment, take care not to directly hit the
fuse box or the windshield wiper motors with
water.
