242IN CASE OF EMERGENCY
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 remote 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.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 trans -
mission 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.
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.
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.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads HOT (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 HOT (H), and you hear continuous
chimes, turn the engine off immediately and
call for service.

IN CASE OF EMERGENCY249
(Continued)
ALL WHEEL DRIVE (AWD) MODELS
The manufacturer recommends towing your
vehicle with all four wheels OFF the ground
using a flatbed.
If the transmission and driveline are operable,
AWD models can also be towed with the ignition
in the ON/RUN mode, the transmission in
NEUTRAL (not in PARK!), and the rear wheels
OFF the ground with no limitation on speed or
distance. Since the ignition MUST be in the ON/
RUN mode to tow in this manner, AWD vehicles
must be towed with ALL FOUR wheels OFF the
ground (e.g. on a flatbed truck) if the key fob is
unavailable.
REAR-WHEEL DRIVE (RWD) MODELS
The manufacturer recommends towing your
vehicle with all four wheels OFF the ground
using a flatbed.
If flatbed equipment is not available, and the
transmission is operable, this vehicle may be
flat towed (with all four wheels on the ground)
under the following conditions:

The automatic transmission must be in
NEUTRAL. Refer to "Manual Park Release" in this
section for instructions on shifting the transmis -
sion to NEUTRAL when the engine is off.

The towing speed must not exceed 30 mph
(48 km/h).
The towing distance must not exceed
30 miles (48 km).
If the transmission is not operable, or the
vehicle must be towed faster than 30 mph
(48 km/h) or farther than 30 miles (48 km),
then the only acceptable method of towing is
with a flatbed truck.
ENHANCED ACCIDENT RESPONSE SYSTEM
(EARS)
This vehicle is equipped with an Enhanced
Accident Response System.

Please refer to “Occupant Restraint Systems” in
“Safety” for further information on the Enhanced
Accident Response System (EARS) function.

EVENT DATA RECORDER (EDR)
This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an EDR is
to record data that will assist in understanding
how a vehicle’s systems performed under
certain crash or near crash-like situations, such
as an air bag deployment or hitting a road
obstacle.
Please refer to “Occupant Restraint Systems” in
“Safety” for further information on the Event
Data Recorder (EDR).
The manufacturer does not recommend
towing this vehicle using a tow dolly.
Vehicle damage may occur.
CAUTION!
Towing this vehicle using any other method
can cause severe transmission and/or
transfer case damage.
CAUTION! (Continued)
Damage from improper towing is not
covered under the New Vehicle Limited
Warranty.
CAUTION!CAUTION!

Towing this vehicle in violation of the above
requirements can cause severe transmission
damage. Damage from improper towing is not
covered under the New Vehicle Limited Warranty.

ENGINE AIR CLEANER FILTER
Refer to the “Maintenance Plan” in this section
for the proper maintenance intervals.
NOTE:
Be sure to follow the “Severe Duty Conditions”
maintenance interval if applicable.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner
filters varies considerably. Only high quality
filters should be used to ensure most efficient
service. Mopar engine air cleaner filters are a
high quality filter and are recommended.
AIR CONDITIONER MAINTENANCE
For best possible performance, your air
conditioner should be checked and serviced by
an authorized dealer at the start of each warm
season. This service should include cleaning of
the condenser fins and a performance test.
Drive belt tension should also be checked at
this time.
Refrigerant Recovery And Recycling
R-134a — If Equipped

R-134a Air Conditioning Refrigerant is a hydroflu -
orocarbon (HFC) that is an ozone-friendly
substance. The manufacturer recommends that
air conditioning service be performed by an
authorized dealer or other service facilities using
recovery and recycling equipment.

NOTE:
Use only manufacturer approved A/C system
PAG compressor oil and refrigerants.
Refrigerant Recovery And Recycling
R-1234yf — If Equipped
R-1234yf Air Conditioning Refrigerant is a
hydrofluoroolefin (HFO) that is endorsed by the
Environmental Protection Agency and is an
ozone-friendly substance with a low
global-warming potential. The manufacturer
WARNING!

The air induction system (air cleaner, hoses,
etc.) can provide a measure of protection in the
case of engine backfire. Do not remove the air
induction system (air cleaner, hoses, etc.)
unless such removal is necessary for repair or
maintenance. Make sure that no one is near
the engine compartment before starting the
vehicle with the air induction system (air
cleaner, hoses, etc.) removed. Failure to do so
can result in serious personal injury.
WARNING!
Use only refrigerants and compressor lubri -
cants approved by the manufacturer for
your air conditioning system. Some unap -
proved refrigerants are flammable and can
explode, injuring you. Other unapproved
refrigerants or lubricants can cause the
system to fail, requiring costly repairs.
Refer to Warranty Information Book, for
further warranty information.
The air conditioning system contains refrig -
erant under high pressure. To avoid risk of
personal injury or damage to the system,
adding refrigerant or any repair requiring
lines to be disconnected should be done by
an experienced technician.
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals can
damage your air conditioning components.
Such damage is not covered by the New
Vehicle Limited Warranty.

ACCESSORY DRIVE BELT INSPECTION
WARNING!
Do not attempt to inspect an accessory
drive belt with vehicle running.
When working near the radiator cooling fan,
disconnect the fan motor lead. The fan is
temperature controlled and can start at any
time regardless of ignition mode. You could
be injured by the moving fan blades.
