2011 JEEP GRAND CHEROKEE battery

The Advanced Front Airbags will not deploy in all frontal
collisions, including some that may produce substantial
vehicle damage — for example, some pole collisions,
truck underrides, and angle offset collisions. On the other
hand, depending on the type and location of impact,
Advanced Front Airbags may deploy in crashes with
little vehicle front-end damage but that produce a severe
initial deceleration.
The side airbags will not deploy in all side collisions. Side
airbag deployment will depend on the severity and type
of collision.
Because airbag sensors measure vehicle deceleration over
time, vehicle speed and damage by themselves are not
good indicators of whether or not an airbag should have
deployed.
Seat belts are necessary for your protection in all acci-
dents, and also are needed to help keep you in position,
away from an inflating airbag.The ORC monitors the readiness of the electronic parts of
the airbag system whenever the ignition switch is in the
START or ON/RUN position. If the key is in the OFF
position, in the ACC position, or not in the ignition, the
airbag system is not on and the airbags will not inflate.
The ORC contains a backup power supply system that
may deploy the airbags even if the battery loses power or
it becomes disconnected prior to deployment.
Also, the ORC turns on the Airbag Warning
Light in the instrument panel for approxi-
mately four to eight seconds for a self-check
when the ignition is first turned on. After the
self-check, the Airbag Warning Light will turn off. If the
ORC detects a malfunction in any part of the system, it
turns on the Airbag Warning Light, either momentarily
or continuously. A single chime will sound if the light
comes on again after initial startup.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 75

Because airbag sensors estimate deceleration over time,
vehicle speed and damage are not good indicators of
whether or not an airbag should have deployed.
NOTE:In a rollover the pretensioners, SAB and/or
SABIC airbags may deploy on both sides of the vehicle.
Front And Side Impact Sensors
In front and side impacts, front and side impact sensors
can aid the ORC in determining the appropriate response
to certain impact events.
Enhanced Accident Response System
In the event of an impact causing airbag deployment, 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 System perform the follow-
ing functions:
•Cut off fuel to the engine.
•Flash hazard lights as long as the battery has power or
until the ignition key is turned off.
•Turn on the interior lights, which remain on as long as
the battery has power or until the ignition key is
removed.
•Unlock the doors automatically.
If A Deployment Occurs
The Advanced Front Airbags are designed to deflate
immediately after deployment.
NOTE: Front and/or side airbags will not deploy in all
collisions. This does not mean something is wrong with
the airbag system.
If you do have a collision which deploys the airbags, any
or all of the following may occur:
•The nylon airbag material may sometimes cause abra-
sions and/or skin reddening to the driver and front

Interior Lights
Courtesy and dome lights are turned on when the front
doors are opened, when the dimmer control (rotating
wheel on the right side of the headlight switch) is rotated
to the its farthest upward position, or if equipped, when
the UNLOCK button is pressed on the Remote Keyless
Entry (RKE) transmitter. 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 vehicle’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 controlto 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.

Lights-On Reminder
If the headlights, parking lights, or cargo lights are left on
after the ignition is turned OFF, a chime will sound when
the driver ’s door is opened.
Battery Saver
To protect the life of your vehicle’s battery, load shedding
is provided for both the interior and exterior lights.
If the ignition is OFF and any door is left ajar for
10 minutes or the dimmer control is rotated all the way
up to the dome ON position for 10 minutes, the interior
lights will automatically turn off.
If the headlights remain on while the ignition is cycled
OFF, the exterior lights will automatically turn off after
eight minutes. If the headlights are turned on and left on
for eight minutes while the ignition is OFF, the exterior
lights will automatically turn off.NOTE:
Battery saver mode is cancelled if the ignition is
ON.
Front Map/Reading Lights
The front map/reading lights are mounted in the over-
head console.

GARAGE DOOR OPENER — IF EQUIPPED
HomeLinkreplaces up to three remote controls (hand-
held transmitters) that operate devices such as garage
door openers, motorized gates, lighting or home security
systems. The HomeLink unit operates off your vehicle’s
battery.
The HomeLink buttons that are located in the overhead
console designate the three different HomeLink chan-
nels.
NOTE:HomeLink is disabled when the Vehicle Secu-
rity Alarm is active.

WARNING!
•Your motorized door or gate will open and close
while you are training the universal transceiver.
Do not train the transceiver if people, pets or other
objects are in the path of the door or gate. Only use
this transceiver with a garage door opener that has
a “stop and reverse” feature as required by Federal
safety standards. This includes most garage door
opener models manufactured after 1982. Do not
use a garage door opener without these safety
features. Call toll-free 1–800–355–3515 or, on the
Internet at www.HomeLink.com for safety infor-
mation or assistance.
•Vehicle exhaust contains carbon monoxide, a dan-
gerous gas. Do not run your vehicle in the garage
while training the transceiver. Exhaust gas can
cause serious injury or death.
Programming HomeLink
Before You Begin
If you have not trained any of the HomeLink buttons,
erase all channels before you begin training.
To do this, press and hold the two outside buttons for up
to 20 seconds until the red indicator flashes.
It is recommended that a new battery be placed in the
handheld transmitter of the device that is being copied to
HomeLink for more efficient training and accurate
transmission of the radio-frequency signal.
Your vehicle should be parked outside of the garage
when programming.
1. Turn the ignition switch to the ON/RUN position.
2. Hold the battery side of the handheld transmitter
away from the HomeLink button you wish to program.

Reprogramming A Single HomeLinkButton
To reprogram a channel that has been previously trained,
follow these steps:
1. Turn the ignition switch to the ON/RUN position.
2. Press and hold the desired HomeLink button until
the indicator light begins to flash after 20 seconds. Do not
release the button.
3. Without releasing the button, proceed with Program-
ming HomeLink Step 2 and follow all remaining steps.
Security
It is advised to erase all channels before you sell or turn
in your vehicle.
To do this, press and hold the two outside buttons for
20 seconds until the red indicator flashes. Note that all
channels will be erased. Individual channels cannot be
erased. The HomeLink
Universal Transceiver is disabled when
the Vehicle Security Alarm is active.
Troubleshooting Tips
If you are having trouble programming HomeLink, here
are some of the most common solutions:
•Replace the battery in the original transmitter.
•Press the LEARN button on the Garage Door Opener
to complete the training for a Rolling Code.
•Did you unplug the device for training, and remember
to plug it back in?
If you have any problems, or require assistance, please
call toll-free 1–800–355–3515 or, on the Internet at
www.HomeLink.com for information or assistance.
