Positive (+) Battery Post – Diesel Engine

NOTE:The positive (+) battery post is covered with a protective
cap. Lift up on the cap to gain access to the post.
If your vehicle is equipped with a Stop/Start system, it will
be equipped with two batteries
Úpage 147.
See the following steps to prepare for jump starting:

1. Apply the parking brake, shift the automatic transmission into PARK (P) (manual transmission in
NEUTRAL) and turn the ignition OFF.

2. Turn off the heater, radio, and all electrical accessories.
3. Pull upward and remove the protective cover over the positive (+) battery post.
4. If using another vehicle to jump start the battery, park the vehicle within the jumper cable’s reach, apply the
parking brake and make sure the ignition is OFF.
JUMP STARTING PROCEDURE
Connecting The Jumper Cables

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

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 the
fuel injection system.

Jump Starting Label

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.
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.

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, 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
discharged vehicle.
5. Reinstall the protective cover over the positive (+)
post of the discharged vehicle.
NOTE:If frequent jump starting is required to start your vehicle
you should have the battery and charging system tested at
an authorized dealer.
IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be serviced by
an authorized dealer.
Potential signs of vehicle overheating:
 Temperature gauge is at HOT (H)
 Strong smell of coolant
 White smoke coming from engine or exhaust
 Coolant bottle coolant has bubbles present In the event it is observed that the temperature gauge is
moving towards or close to the HOT (H) position, 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 (N), but do not increase the engine idle speed
while preventing vehicle motion with the brakes.
 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.
 You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control
to high. This allows the heater core to act as a supple -
ment to the radiator and aids in removing heat from the
engine cooling system.
CAUTION!
Make sure at all times that unused ends of jumper
cables are not contacting each other or either vehicle
while making connections. Failure to follow these
procedures could result in damage to the charging
system of the booster vehicle or the discharged vehicle.
CAUTION!

Do not run the booster vehicle engine above 2,000 RPM
since it provides no charging benefit, wastes fuel, and
can damage booster vehicle engine.

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.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap when
the radiator or coolant bottle is hot.

IN CASE OF EMERGENCY301
MANUAL PARK RELEASE
In order to move the vehicle in cases where the
transmission will not shift out of PARK (P) (such as a
depleted battery), a Manual Park Release is available. See the following steps to use the Manual Park Release:

1. Firmly apply the parking brake.

2. Using a small screwdriver or similar tool, remove the
manual park release cover located in front of the gear
selector, to access the release tether strap.

Manual Park Release Cover

3. Fish the tether strap up through the opening in the console base.

Tether Strap

4. Press and maintain firm pressure on the brake pedal.
5. Pull the tether strap up until the release lever locks into place in the vertical position. The vehicle is now
out of PARK (P) and can be moved. Release the
parking brake only when the vehicle is securely
connected to a tow vehicle.

Vertical Released Position

CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the temperature gauge reads “H,” pull over
and stop the vehicle. Idle the vehicle with the air condi -
tioner turned off until the pointer drops back into the
normal range. If the pointer remains on the “H” and you
hear continuous chimes, turn the engine off immedi -
ately and call for service.
WARNING!
Always secure your vehicle by fully applying the parking
brake before activating the Manual Park Release. In
addition, you should be seated in the driver’s seat with
your foot firmly on the brake pedal when activating the
Manual Park Release. Activating the Manual Park
Release will allow your vehicle to roll away if it is not
secured by the parking brake, or by proper connection
to a tow vehicle. Activating the Manual Park Release on
an unsecured vehicle could lead to serious injury or
death for those in or around the vehicle.

Original Tether Position

3. Tuck the tether strap into the base of the console, and reinstall the cover.
NOTE:When the lever is locked in the release position the access
cover cannot be reinstalled.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it can
often be moved using a rocking motion. Turn the steering
wheel right and left to clear the area around the front
wheels. For vehicles with automatic transmission, push
and hold the lock button on the gear selector. Then, shift
back and forth between DRIVE (D) and REVERSE (R) (with
automatic transmission) or SECOND (2) gear and
REVERSE (R) (with manual transmission), while gently
pressing the accelerator. Use the least amount of
accelerator pedal pressure that will maintain the rocking
motion, without spinning the wheels or racing the engine.
NOTE:
For vehicles with automatic transmission: Shifts
between DRIVE (D) and REVERSE (R) can only be
achieved at wheel speeds of 5 mph (8 km/h) or less.
Whenever the transmission remains in NEUTRAL (N)
for more than two seconds, you must press the brake
pedal to engage DRIVE (D) or REVERSE (R).
 Push the ESC OFF button to place the Electronic
Stability Control (ESC) system in “Partial OFF” mode,
before rocking the vehicle
Úpage 246. Once the
vehicle has been freed, push the ESC OFF button again
to restore “ESC On” mode.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause damage, or even
failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle's wheels
faster than 30 mph (48 km/h) or for longer than
30 seconds continuously without stopping when you
are stuck and do not let anyone near a spinning wheel,
no matter what the speed.
CAUTION!
 Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the
engine to idle with the transmission in NEUTRAL for
at least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce the
risk of clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
 When “rocking” a stuck vehicle by shifting between
DRIVE/SECOND gear and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
 Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure. It
can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmis -
sion shifting occurring).

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial towing service.
If the transmission and drivetrain are operable, disabled 4x4 vehicles may also be towed as described
Úpage 176.
Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for this purpose, following equipment
manufacturer’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing device to
main structural members of the vehicle, not to fascia/
bumpers or associated brackets. State and local laws
regarding vehicles under tow must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
position, not the ACC position.
If the vehicle's battery is discharged, instructions on
shifting the automatic transmission out of PARK (P) in
order to move the vehicle
Úpage 301.
FOUR–WHEEL DRIVE MODELS
FCA US LLC recommends towing with all wheels OFF the
ground. Acceptable methods are to tow the vehicle on a
flatbed or with one end of the vehicle raised and the
opposite end on a towing dolly.
If flatbed equipment is not available and the transfer case
is operable, the vehicle may be towed (in the forward
direction, with ALL wheels on the ground), IF the transfer
case is in NEUTRAL (N) and the transmission is in PARK (P)
(for automatic transmissions) or in gear NOT in NEUTRAL ,
for manual transmissions)

SERVICING AND MAINTENANCE
SCHEDULED SERVICING — GASOLINE
ENGINE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
is required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extremely hot or cold
ambient temperatures will influence when the “Change
Oil” or “Oil Change Required” message is displayed. Have
your vehicle serviced as soon as possible, within the next
500 miles (805 km).On vehicles equipped with instrument cluster display, “Oil
Change Required” will be displayed and a single chime will
sound, indicating that an oil change is necessary.
On non-instrument cluster display equipped vehicles,
“Change Oil” will flash in the instrument cluster odometer
and a single chime will sound, indicating that an oil
change is necessary.
An authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other than
an authorized dealer, the message can be reset by
referring to the steps described under Instrument Cluster
Display for further information
Úpage 108.
NOTE:Under no circumstances should oil change intervals
exceed 10,000 miles (16,000 km), 12 months or 350
hours of engine run time, whichever comes first. The 350
hours of engine run or idle time is generally only a concern
for fleet customers.
