2015 JEEP GRAND CHEROKEE battery

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 ORC will determine
whether to have the Enhanced Accident Response Sys-
tem perform the following functions:
•Cut off fuel to the engine.
•Flash hazard lights as long as the battery has power or
until the ignition is placed in the “OFF” position.
•Turn on the interior lights, which remain on as long as
the battery has power or until the ignition is placed in
the “OFF” position.
•Unlock the doors automatically.
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.
Air Bag Warning Light
The air bags must be ready to inflate for your
protection in a collision. The Occupant Re-
straint Controller (ORC) monitors the internal
circuits and interconnecting wiring associated
with air bag system electrical components.
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition is in the START
or ON/RUN position. If the ignition is in the OFF
position or in the ACC position, the air bag system is not
on and the air bags will not inflate.
78 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The ORC contains a backup power supply system that
may deploy the air bags even if the battery loses power or
it becomes disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition is first placed in the
ON/RUN position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects a mal-
function in any part of the system, it turns on the Air Bag
Warning Light, either momentarily or continuously. A
single chime will sound to alert you if the light comes on
again after initial startup.
The ORC also includes diagnostics that will illuminate
the instrument panel Air Bag Warning Light if a malfunc-
tion is detected that could affect the air bag system. The
diagnostics also record the nature of the malfunction.
While the air bag system is designed to be maintenancefree, if any of the following occurs, have an authorized
dealer service the air bag system immediately.
•The Air Bag Warning Light does not come on during
the four to eight seconds when the ignition is first
placed in the ON/RUN position.
•The Air Bag Warning Light remains on after the four to
eight-second interval.
•The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. In this condition
the air bags may not be ready to inflate for your protec-
tion. Have an authorized dealer service the air bag
system immediately.

Even if the 9-1-1 Call system is fully functional, factors
beyond FCA US LLC’s control may prevent or stop the
9-1-1 Call system operation. These include, but are not
limited to, the following factors:
•Delayed accessories mode is active.
•The ignition is in the OFF position.
•The vehicle’s electrical systems are not intact.
•The 9-1-1 Call system software and/or hardware are
damaged during a crash.
•The vehicle battery loses power or becomes discon-
nected during a vehicle crash.
•Wireless and/or Global Positioning Satellite signals
are unavailable or obstructed.
•Equipment malfunction at the 9-1-1 operator facility.

turn off when the switch is pushed a second time, when
the headlight switch is rotated to the off position, or the
high beam is selected.
Interior Lights
Courtesy and dome lights are turned on when the front
doors are opened or when the dimmer control (rotating
wheel on the right side of the headlight switch) is rotated
to its farthest upward position. If your vehicle is
equipped with Remote Keyless Entry (RKE) and the
UNLOCK button is pressed on the RKE transmitter the
courtesy and dome lights will turn on. When a door is
open and the interior lights are on, rotating the dimmer
control all the way down, to the OFF detent, will cause all
the interior lights to go out. This is also known as the
“Party” mode because it allows the doors to stay open for
extended periods of time without discharging the vehi-
cle’s battery.The brightness of the instrument panel lighting can be
regulated by rotating the dimmer control up (brighter) or
down (dimmer). When the headlights are on you can
supplement the brightness of the odometer, trip odom-
eter, radio and overhead console by rotating the control
to its farthest position up until you hear a click. This
feature is termed the “Parade” mode and is useful when
headlights are required during the day.
