2010 JEEP GRAND CHEROKEE key battery

Key Fob
The Key Fob operates the ignition switch. It also contains
the Remote Keyless Entry (RKE) transmitter and an
emergency key, which stores in the rear of the Key Fob.
The emergency key allows for entry into the vehicle
should the battery in the vehicle or the RKE transmitter
go dead. The emergency key is also for locking the glove
box. You can keep the emergency key with you when
valet parking.
NOTE:Entering a vehicle using the emergency key with
the theft alarm armed, will results in the alarm sounding.
Insert the Key Fob (even if the Key Fob battery is dead)
into the WIN to disarm theft alarm.
To remove the emergency key, slide the mechanical latch
at the top of the Key Fob sideways with your thumb and
then pull the key out with your other hand. NOTE:
You can insert the double-sided emergency key
into the lock cylinders with either side up.
Removing Key Fob From Ignition
Place the shift lever in PARK. Turn the Key Fob to the
OFF position and then remove the Key Fob.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 13

Using the Panic Alarm
To turn the Panic Alarm feature on or off, press and hold
the PANIC button on the RKE transmitter for at least one
second and release. When the Panic Alarm is on, the
headlights and park lamps will flash, the horn will pulse
on and off, and the interior lights will turn on.
The Panic Alarm will stay on for three minutes unless
you turn it off by either pressing the PANIC button a
second time, or drive the vehicle at a speed of 15 mph
(24 km/h) or greater.
NOTE:The interior lights will turn off if you turn the
ignition switch to the ACC or ON position while the
Panic Alarm is activated. However, the exterior lamps
and horn will remain on.
Programming Additional Transmitters
Programming Key Fobs or RKE transmitters may be
performed at an authorized dealer.
Transmitter Battery Replacement
The recommended replacement battery is one CR2032
battery.
NOTE:
•Perchlorate Material — special handling may apply.
See www.dtsc.ca.gov/hazardouswaste/perchlorate
•Do not touch the battery terminals that are on the back
housing or the printed circuit board.
1. Battery access is through a door located on the rear of
the Key Fob. Insert a small, flat blade screwdriver into the
slot and gently pry open the access door.
22 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

1. A weak battery in the RKE transmitter. The expected
life of the battery is a minimum of three years.
2. Closeness to a radio transmitter such as a radio station
tower, airport transmitter, and some mobile or CB radios.
REMOTE STARTING SYSTEM — IF EQUIPPED
This system uses the Remote Keyless Entry
(RKE) transmitter to start the engine conve-
niently from outside the vehicle while still
maintaining security. The system has a range of
approximately 328 ft (100 m).
NOTE: The vehicle must be equipped with an auto-
matic transmission to be equipped with Remote Start.
How to Use Remote Start
All of the following conditions must be met before the
engine will remote start:
•Shift lever in PARK
•Doors closed
•Hood closed
•Liftgate closed
•Hazard switch off
•Brake switch inactive (brake pedal not pressed)
•Ignition key removed from ignition switch
•Battery at an acceptable charge level
•RKE PANIC button not pressed
24 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Front and Side Impact Sensors
In front and side impacts, impact sensors aid the ORC in
determining appropriate response to impact events. Ad-
ditional sensors in the ORC determine the level of airbag
deployment and provide verification.
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 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
passenger as the airbags 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.

NOTE:The sunshade cannot be closed if the sunroof is
open.
Wind Buffeting
Wind buffeting can be described as the perception of
pressure on the ears or a helicopter-type sound in the
ears. Your vehicle may exhibit wind buffeting with the
windows down, or the sunroof (if equipped) in certain
open or partially open positions. This is a normal occur-
rence and can be minimized. If the buffeting occurs with
the rear windows open, open the front and rear windows
together to minimize the buffeting. If the buffeting occurs
with the sunroof open, adjust the sunroof opening to
minimize the buffeting or open any window.
Sunroof Maintenance
Use only a non-abrasive cleaner and a soft cloth to clean
the glass panel.
Ignition OFF Operation
The power sunroof switches remain active for up ap-
proximately ten minutes after the ignition switch has
been turned OFF. Opening either front door will cancel
this feature.
Sunroof Fully Closed
Press the switch forward and release to ensure that the
sunroof is fully closed.
ELECTRICAL POWER OUTLETS
Your vehicle is equipped with 12 Volt (13 Amp) power
outlets that can be used to power cellular phones, small
electronics and other low powered electrical accessories.
The power outlets are labeled with either a “key” or a
“battery” symbol to indicate how the outlet is powered.
Power outlets labeled with a “key” are powered when
the ignition switch is in the ON or ACC position, while
the outlets labeled with a “battery” are connected directly
to the battery and powered at all times.
