PREPARATIONS FOR JUMP START

Supplemental Battery — If Equipped
The battery in your vehicle is located in the right
rear of the engine compartment.

Positive (+) Battery Post – Gas Engine 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
Ú page 169.
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 place the
ignition in OFF mode.

2. Turn off the heater, radio, and all electrical accessories.
WARNING!
Only use the positive battery post on the main
battery to jump start your vehicle. Serious
injury or death could result if you attempt to
jump start using the supplemental battery.
Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Do not
use a booster battery or any other booster
source with an output greater than 12 Volts.
Do not allow cable clamps to touch each
other.
Battery posts, terminals, and related accesso -
ries contain lead and lead compounds. Wash
hands after handling.
If a “fast charger” is used while the battery is
in the vehicle, disconnect both vehicle battery
cables before connecting the charger to the
battery. Do not use a “fast charger” to provide
starting.
WARNING!

23_JT_OM_EN_USC_t.book Page 344

348IN CASE OF EMERGENCY
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 trans -
mission 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 supplement to the radiator and
aids in removing heat from the engine cooling
system.
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

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.
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 conditioner 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
immediately 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.

4. Press and maintain firm pressure on the brake pedal.
5. Pull the tether strap 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

To Reset The Manual Park Release:

1. Pull upward on the tether strap, releasing it from the “locked” position.

2. Lower the Manual Park Release lever downward into its original position.

Original Tether Position
3. Tuck the tether strap into the base of the
console, and reinstall the cover.
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 2 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 Ú page 281.

(Continued)
Once the vehicle has been freed, push the ESC
OFF button again to restore “ESC On” mode.
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
vehicles may also be towed as described on Ú
page 205.
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 sec-
onds 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 (N) for at least one minute after
every five rocking-motion cycles. This will mini -
mize 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 transmission shifting occurring).

IN CASE OF EMERGENCY351
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 348.
FOUR–WHEEL DRIVE MODELS
FCA LLC US 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) Ú page 205.
WITHOUT THE KEY FOB
Special care must be taken when the vehicle is
towed with the ignition in the OFF position. The only
approved method of towing without the key fob is
with a flatbed truck. Proper towing equipment is
necessary to prevent damage to the vehicle.
EMERGENCY TOW HOOKS —
I
F EQUIPPED
If your vehicle is equipped with tow hooks, they are
mounted in the front and the rear fascia/bumpers.

Front Tow Hooks

NOTE:Depending on vehicle trim level, rear tow hooks
may vary.
CAUTION!
Do not use sling type equipment when towing.
Vehicle damage may occur.
When securing the vehicle to a flatbed truck,
do not attach to front or rear suspension
components. Damage to your vehicle may
result from improper towing.
CAUTION!
Front or rear wheel lifts must not be used (if
the remaining wheels are on the ground).
Internal damage to the transmission or
transfer case will occur if a front or rear wheel
lift is used when towing.
Towing this vehicle in violation of the
approved requirements can cause severe
transmission and/or transfer case damage.
Damage from improper towing is not covered
under the New Vehicle Limited Warranty.
