Some vehicles may be equipped with a rear cupholder that
consists of two cup wells for rear passenger convenience.
Electrical Power Outlets
The auxiliary 12 Volt (13 Amp) power outlets can provide
power for in-cab accessories designed for use with the
standard “cigar lighter” plug. The 12 Volt power outlets
and 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 key 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.
NOTE:
To ensure proper operation, a Mopar knob and
element must be used.
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.

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.
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.
CAUTION!
Many accessories that can be plugged in draw power
from the vehicle’s battery, even when not in use (i.e.,
cellular phones, etc.). Eventually, if plugged in long
enough, the vehicle’s battery will discharge suffi-
ciently to degrade battery life and/or prevent the
engine from starting.
Accessories that draw higher power (i.e., coolers,
vacuum
cleaners,
lights,
etc.),
will
discharge
the
battery even more quickly. Only use these intermit-
tently and with greater caution.

FUSES
WARNING!
When replacing a blown fuse, always use an appro-
priate replacement fuse with the same amp rating as
the original fuse. Never replace a fuse with another
fuse of higher amp rating. Never replace a blown
fuse with metal wires or any other material. 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 autho-
rized dealer.

CAUTION!
When installing the power distribution center cover,
it is important to ensure the cover is properly posi-
tioned 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.
(Continued)
CAUTION!
(Continued)
When replacing a blown fuse, it is important to use
only a fuse having the correct amperage rating. The
use of a fuse with a rating other than indicated 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.
338
IN 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.
NOTE:
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.
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.
1. Apply the parking brake, shift the automatic transmis-
sion into PARK and turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary 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.
Correct Positive Jumping Location
346
IN CASE OF EMERGENCY
WARNING!
Do not allow vehicles to touch each other as this could
establish a ground connection and personal injury
could result.
Jump Starting Procedure
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.
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 (exposed metal part of
the discharged vehicle’s engine) away from the battery
and the fuel injection system.
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. Only use the specific ground point, do
not use any other exposed metal parts.
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.
7
IN CASE OF EMERGENCY
347
CAUTION!
Do not connect jumper cable to any of the fuses on the
positive battery terminal. The resulting electrical cur-
rent will blow the fuse.
6. Once the engine is started, remove the jumper cables in
the reverse sequence:
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 in-
spected at an authorized dealer.
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.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase the engine idle speed
while preventing vehicle motion with the brakes.
NOTE:
There are steps that you can take to slow down an
impending overheat condition:
If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.

SERVICING AND MAINTENANCE
INSTALLATION OF RADIO TRANSMITTING
EQUIPMENT
Special design considerations are incorporated into this
vehicle’s electronic system to provide immunity to radio
frequency signals. Mobile two-way radios and telephone
equipment must be installed properly by trained person-
nel. The following must be observed during installation.
The positive power connection should be made directly
to the battery and fused as close to the battery as possible.
The negative power connection should be made to body
sheet metal adjacent to the negative battery connection.
This connection should not be fused.
Antennas for two-way radios should be mounted on the
roof or the rear area of the vehicle. Care should be used
in mounting antennas with magnet bases. Magnets may
affect
the
accuracy
or
operation
of
the
compass
on
vehicles so equipped.
The antenna cable should be as short as practical and
routed away from the vehicle wiring when possible. Use
only fully shielded coaxial cable.
Carefully match the antenna and cable to the radio to
ensure a low Standing Wave Ratio (SWR).
Mobile radio equipment with output power greater than
normal may require special precautions.
All installations should be checked for possible interfer-
ence between the communications equipment and the
vehicle’s electronic systems.
NOTE:
For vehicle’s equipped with Keyless Enter-
N-Go, place the ignition in the RUN posi-
tion with the Engine ON. Make sure to
program HomeLink with the vehicle out-
side of the garage, or with the garage door
open at all times.
2. Push and hold the desired HomeLink but-
ton until the instrument cluster display
shows the “CHANNEL # TRAINING” mes-
sage.
Do not release the button.
3.
Without releasing the button
, proceed with
Step 2 in “Programming HomeLink To A
Garage Door Opener” and follow all re-
maining steps.

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 sys-
tem failure.
• When replacing a blown fuse, it is impor-
tant to use only a fuse having the correct
amperage rating. The use of a fuse with
a rating other than indicated may result
in a dangerous electrical system over-
load. If a properly rated fuse continues
to blow, it indicates a problem in the
circuit that must be corrected.
JACKING AND TIRE CHANGING
WARNING!
• Do not attempt to change a tire on the
side of the vehicle close to moving traf-
fic. Pull far enough off the road to avoid
the danger of being hit when operating
the jack or changing the wheel.
• Being under a jacked-up vehicle is dan-
gerous. The vehicle could slip off the
jack
and
fall
on
you.
You
could
be
crushed. Never put any part of your body
under a vehicle that is on a jack. If you
need to get under a raised vehicle, take
it to a service center where it can be
raised on a lift.
• Never start or run the engine while the
vehicle is on a jack.
• The jack is designed to be used as a tool
for changing tires only. The jack should
not be used to lift the vehicle for service
purposes. The vehicle should be jacked
on a firm level surface only. Avoid ice or
slippery areas.
4500/5500 Models
These vehicles do not come equipped with a
jack.
NOTE:
Jacking
and
tire
changing
on
4500/
5500 models should be performed by an
authorized dealer, or knowledgeable service
personnel with the appropriate heavy duty
equipment, like a tire service company.
Preparations For Jacking
1. Park the vehicle on a firm, level surface.
Avoid ice or slippery areas.
WARNING!
Do not attempt to change a tire on the side
of the vehicle close to moving traffic, pull
far enough off the road to avoid being hit
when operating the jack or changing the
wheel.
2. Place the gear selector into PARK. On
four-wheel drive vehicles, shift the trans-
fer case to the 4L position.
3. Turn on the Hazard Warning flasher.
IN CASE OF EMERGENCY
160
NOTE:
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 di-
rectly off positive post which has a positive
(+)
symbol on or around the post.
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.
1. Apply the parking brake, shift the auto-
matic transmission into PARK and turn
the ignition to LOCK.
2. Turn off the heater, radio, and all unnec-
essary 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.
WARNING!
Do not allow vehicles to touch each other
as this could establish a ground connec-
tion and personal injury could result.
Jump Starting Procedure
WARNING!
Failure to follow this jump starting proce-
dure 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 ve-
hicle.
Connecting The Jumper Cables
1. Connect the positive
(+)
end of the jumper
cable to the positive
(+)
post of the dis-
charged vehicle.
Positive Jumping Location
165
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
(exposed metal part of the discharged
vehicle’s engine) away from the battery
and the fuel injection system.
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.
Only
use
the
specific
ground point, do not use any other exposed
metal parts.
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.
CAUTION!
Do not connect jumper cable to any of the
fuses on the positive battery terminal. The
resulting electrical current will blow the
fuse.
6. Once the engine is started, remove the
jumper cables in the reverse sequence:
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 nega-
tive
(-)
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 posi-
tive
(+)
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.
CAUTION!
Accessories
plugged
into
the
vehicle
power outlets draw power from the vehi-
cle’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 dis-
charge sufficiently to degrade battery life
and/or prevent the engine from starting.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
• On the highways — slow down.
