The DEF gauge may also not immediately
update after a refill if the temperature of the
DEF fluid is below 12°F (-11°C). The DEF
line heater will possibly warm up the DEF
fluid and allow the gauge to update after a
period of run time. Under very cold condi -
tions, it is possible that the gauge may not
reflect the new fill level for several drives.
Excessive overfilling of the DEF tank can
result in a MIL lamp/fault code and inaccu-
rate level readings.
Refilling With Nozzles
You can fill up at any DEF distributor.
Proceed as follows:
Insert the DEF nozzle in the filler, start
refilling and stop refilling at the first shut-off
(the shut-off indicates that the DEF tank is
full). Do not proceed with the refilling, to
prevent spillage of DEF.
Extract the nozzle.
Refilling With Containers
Proceed as follows:
Check the expiration date.
Read the advice for use on the label before
pouring the content of the bottle into the
DEF tank.
If systems which cannot be screwed in
(e.g. tanks) are used for refilling, after the
indication appears on the instrument panel
display Úpage 121 fill the DEF tank with no
more than 2 gal (8 L).
If containers which can be screwed to the
filler are used, the reservoir is full when the
DEF level in the container stops pouring out.
Do not proceed further.
3. Stop filling the DEF tank immediately when any of the following happen: DEF stops flowing
from the fill bottle into the DEF fill inlet, DEF
splashes out the fill inlet, or a DEF pump
nozzle automatically shuts off.
4. Reinstall cap onto DEF fill inlet.
VEHICLE LOADING
CERTIFICATION LABEL
As required by National Highway Traffic Safety
Administration regulations, your vehicle has a
certification label affixed to the driver's side door or
pillar.
CAUTION!
To avoid DEF spillage, and possible damage to
the DEF tank from overfilling, do not “top off”
the DEF tank after filling.
DO NOT OVERFILL. DEF will freeze below 12ºF
(-11ºC). The DEF system is designed to work in
temperatures below the DEF freezing point,
however, if the tank is overfilled and freezes,
the system could be damaged.
When DEF is spilled, clean the area immedi -
ately with water and use an absorbent mate -
rial to soak up the spills on the ground.
Do not attempt to start your engine if DEF is
accidentally added to the diesel fuel tank as it
can result in severe damage to your engine,
including but not limited to failure of the fuel
pump and injectors.
Never add anything other than DEF to the tank
– especially any form of hydrocarbon such as
diesel fuel, fuel system additives, gasoline, or
any other petroleum-based product. Even a
very small amount of these, less than
100 parts per million or less than 1 oz. per
78 gal (295 L) will contaminate the entire DEF
system and will require replacement. If
owners use a container, funnel or nozzle when
refilling the tank, it should either be new or
one that is has only been used for adding DEF.
Mopar® provides an attachable nozzle with its
DEF for this purpose.
CAUTION!

Enhanced Accident Response System
In the event of an impact, if the communication
network remains intact, and the power remains
intact, depending on the nature of the event, the
Occupant Restraint Controller (ORC) will determine
whether to have the Enhanced Accident Response
System perform the following functions:
Cut off fuel to the engine (if equipped)
Cut off battery power to the electric motor (if
equipped)
Flash hazard lights as long as the battery has
power
Turn on the interior lights, which remain on as
long as the battery has power or for 15 minutes
from the intervention of the Enhanced Accident
Response System
Unlock the power door locks
Your vehicle may also be designed to perform any
of these other functions in response to the
Enhanced Accident Response System:
Turn off the Fuel Filter Heater, Turn off the HVAC
Blower Motor, Close the HVAC Circulation Door
Cut off battery power to the:
Engine
Electric Motor (if equipped)
Electric power steering
Brake booster
Electric park brake
Automatic transmission gear selector
Horn
Front wiper
NOTE:After an accident, remember to cycle the ignition to
the STOP (OFF/LOCK) position and remove the key
from the ignition switch to avoid draining the
battery. Carefully check the vehicle for fuel leaks in
the engine compartment and on the ground near
the engine compartment and fuel tank before
resetting the system and starting the engine. If
there are no fuel leaks or damage to the vehicle
electrical devices (e.g. headlights) after an
accident, reset the system by following the
procedure described below. If you have any doubt,
contact an authorized dealer.
Enhanced Accident Response System
Reset Procedure
In order to reset the Enhanced Accident Response
System functions after an event, the ignition switch
must be changed from ignition START or ON/RUN
to ignition OFF. Carefully check the vehicle for fuel
leaks in the engine compartment and on the
ground near the engine compartment and fuel
tank before resetting the system and starting the engine. After an accident, if the vehicle will not
start after performing the reset procedure, the
vehicle must be towed to an authorized dealer to
be inspected and to have the Enhanced Accident
Response System reset.
Maintaining Your Air Bag System
WARNING!
Modifications to any part of the air bag system
could cause it to fail when you need it. You
could be injured if the air bag system is not
there to protect you. Do not modify the compo
-
nents or wiring, including adding any kind of
badges or stickers to the steering wheel hub
trim cover or the upper passenger side of the
instrument panel. Do not modify the front
fascia/bumper, vehicle body structure, or add
aftermarket side steps or running boards.
It is dangerous to try to repair any part of the
air bag system yourself. Be sure to tell anyone
who works on your vehicle that it has an air
bag system.

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.
