2018 JEEP CHEROKEE BATTERY

If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.
NOTE:
Front and/or side air bags will not deploy in
all collisions. This does not mean something
is wrong with the air bag system.
If you do have a collision which deploys the
air bags, any or all of the following may occur:
• The air bag material may sometimes causeabrasions and/or skin reddening to the oc-
cupants as the air bags deploy and unfold.
The abrasions are similar to friction rope
burns or those you might get sliding along a
carpet or gymnasium floor. They are not
caused by contact with chemicals. They are
not permanent and normally heal quickly.
However, if you haven’t healed significantly
within a few days, or if you have any blis-
tering, see your doctor immediately.
• As the air bags deflate, you may see some smoke-like particles. The particles are a
normal by-product of the process that gen-
erates the non-toxic gas used for air bag
inflation. These airborne particles may irri-
tate the skin, eyes, nose, or throat. If you have skin or eye irritation, rinse the area
with cool water. For nose or throat irritation,
move to fresh air. If the irritation continues,
see your doctor. If these particles settle on
your clothing, follow the garment manufac-
turer’s instructions for cleaning.
Do not drive your vehicle after the air bags
have deployed. If you are involved in another
collision, the air bags will not be in place to
protect you.
WARNING!
Deployed air bags and seat belt preten-
sioners cannot protect you in another col-
lision. Have the air bags, seat belt preten-
sioners, and the seat belt retractor
assemblies replaced by an authorized
dealer immediately. Also, have the Occu-
pant Restraint Controller System serviced
as well.
NOTE:
• Air bag covers may not be obvious in the interior trim, but they will open during air
bag deployment. • After any collision, the vehicle should be
taken to an authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communica-
tion network remains intact, and the power
remains intact, depending on the nature of
the event, the ORC will determine whether to
have the Enhanced Accident Response Sys-
tem 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 En-
hanced Accident Response System.
• Unlock the power door locks.SAFETY
102

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 theHVAC Blower Motor, Close the HVAC Circu-
lation 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
– Headlamp washer pump 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 com-
partment 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.
Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident Re-
sponse System functions after an event, the
ignition switch must be changed from igni-
tion START or ON/RUN to ignition OFF. Care-
fully 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.
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 components or wiring, includ-
ing adding any kind of badges or stickers
to the steering wheel hub trim cover or the
upper right side of the instrument panel.
Do not modify the front 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.
• Do not attempt to modify any part of your
air bag system. The air bag may inflate
accidentally or may not function prop-
erly if modifications are made. Take your
vehicle to an authorized dealer for any
air bag system service. If your seat, in-
cluding your trim cover and cushion,
needs to be serviced in any way (includ-

The starter is allowed to crank for up to
30-second intervals. Waiting a few minutes
between such intervals will protect the starter
from overheating.
WARNING!
• Before exiting a vehicle, always come toa complete stop, then shift the auto-
matic transmission into PARK and apply
the parking brake.
• Always make sure the keyless ignition
node is in the OFF mode, key fob is
removed from the vehicle and vehicle is
locked.
• Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Leaving children in a vehicle unattended
is dangerous for a number of reasons. A
child or others could be seriously or
fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the gear selector.
• Do not leave the key fob in or near the
vehicle, or in a location accessible to
children, and do not leave the ignition of
a vehicle equipped with Keyless Enter-
WARNING!
N-Go in the ACC or ON/RUN mode. A
child could operate power windows,
other controls, or move the vehicle.
• Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury
or death.
NOTE:
Engine start up in very low ambient tempera-
ture could result in evident white smoke. This
condition will disappear as the engine warms
up.
CAUTION!
The engine is allowed to crank as long as
30 seconds. If the engine fails to start
during this period, please wait at least two
minutes for the starter to cool before re-
peating start procedure.
Battery Blanket Usage
A battery loses 60% of its cranking power as
the battery temperature decreases to 0°F
(-18°C). For the same decrease in tempera-
ture, the engine requires twice as much
power to crank at the same RPM. The use of
battery blankets will greatly increase starting
capability at low temperatures. Suitable bat-
tery blankets are available from your autho-
rized Mopar dealer.
Normal Starting Procedure — Keyless
Enter-N-Go
