2023 JEEP WRANGLER battery

STARTING AND OPERATING147
If the “SERVICE POWER STEERING” message and a
flashing icon are displayed on the instrument cluster
screen, it indicates that the vehicle needs to be taken to
an authorized dealer for service. It is likely the vehicle has
lost power steering assistance
Úpage 108.
If the “POWER STEERING HOT” message and an icon are
displayed on the instrument cluster screen, it indicates
that extreme steering maneuvers may have occurred,
which caused an over temperature condition in the power
steering system. You will lose power steering assistance
momentarily until the over temperature condition no
longer exists. Once driving conditions are safe, pull over
and let vehicle idle for a few moments until the light turns
off
Úpage 108.
NOTE:
 Even if power steering assistance is no longer opera -
tional, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at very low vehicle speeds
and during parking maneuvers.
 If the condition persists, see an authorized dealer for
service.
STOP/START SYSTEM — AUTOMATIC
TRANSMISSION (IF EQUIPPED)
The Engine Stop/Start (ESS) function is designed to
reduce fuel consumption. The system will stop the engine
automatically during a vehicle stop if the required
conditions are met. Releasing the brake pedal or pressing
the accelerator pedal will automatically restart the engine. ESS vehicles have been upgraded with a heavy-duty
starter, enhanced battery, and other upgraded engine
parts, to handle the additional engine starts. Vehicles
equipped with eTorque contain a heavy-duty motor
generator and an additional hybrid electric battery to store
energy from vehicle deceleration for use on engine startup
after a stop as well as providing launch torque assist.
NOTE:It is recommended that Stop/Start system be disabled
during off-road use.
Secondary Battery
Your vehicle may be equipped with a secondary battery
used to power the Stop/Start system and the 12 Volt
vehicle electrical system. The secondary battery is located
behind the wheel well for the front passenger wheel.

Battery Locations

AUTOSTOP MODE
The Stop/Start feature is enabled after every driver
ignition start. At that time, the system will go into STOP/
START READY and if all other conditions are met, can go
into a STOP/START AUTOSTOP ACTIVE Autostop mode.
To Activate The Autostop Mode, The Following Must Occur:

The system must be in STOP/START READY state. A
STOP/START READY message will be displayed in the
instrument cluster display within the Stop/Start
section
Úpage 108.
 The vehicle must be completely stopped.
 The shifter must be in a forward gear and the brake
pedal pressed.
1 — Primary Battery
2 — Secondary Battery
WARNING!
 Vehicles with the Stop/Start system will be equipped
with two batteries. Both the main and the supple -
mental batteries must be disconnected to
completely de-energize the 12 Volt electrical system.
 Serious injury or death could result if you do not
disconnect both batteries. To learn how to properly
disconnect, see an authorized dealer.

TOWING TIPS
Before setting out on a trip, practice turning, stopping and
backing the trailer in an area away from heavy traffic.
If using a manual transmission vehicle for trailer towing,
all starts must be in FIRST gear to avoid excessive clutch
slippage.
Automatic Transmission — If Equipped
Select the DRIVE range when towing. The transmission
controls include a drive strategy to avoid frequent shifting
when towing. However, if frequent shifting does occur
while in DRIVE, you can use the AutoStick shift control to
manually select a lower gear.
NOTE:Using a lower gear while operating the vehicle under heavy
loading conditions, will improve performance and extend
transmission life by reducing excessive shifting and heat
buildup. This action will also provide better engine
braking.
AutoStick — If Equipped
When using the AutoStick shift control, select the
highest gear that allows for adequate performance and
avoids frequent downshifts. For example, choose “5” if
the desired speed can be maintained. Choose “4” or
“3” if needed to maintain the desired speed.
 To prevent excess heat generation, avoid continuous
driving at high RPM. Return to a higher gear or vehicle
speed when grade and road conditions allow.
Cruise Control — If Equipped
Do not use in hilly terrain or with heavy loads.
 When using the Cruise Control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
 Use Cruise Control in flat terrain and with light loads to
maximize fuel efficiency.

2. Once a connection between the vehicle and a
SiriusXM Guardian™ Customer Care agent is made,
the agent will stay on the line with you.
NOTE:Calls between the vehicle occupants and the SiriusXM
Guardian™ Customer Care center may be recorded or
monitored for quality assurance purposes. Through your
enrollment in and use of the SiriusXM Guardian™
connected services, you consent to being recorded.
SOS Call System Limitations
Vehicles that have been purchased in the US and that
travel into Mexico and Canada may have limited services.
In particular, responses to SOS calls or other emergency
services may be unavailable or very limited. Vehicles
purchased outside the United States and Canada are
unable to receive SiriusXM Guardian™ connected
services.
If the SOS Call system detects a malfunction, any of the
following may occur at the time the malfunction is
detected:
The light will continuously be illuminated red.
 The screen will display the following message “Vehicle
phone requires service. Please contact your dealer.”
 An in-vehicle audio message will state “Vehicle phone
requires service. Please contact your dealer.”
Even if the SOS Call system is fully functional, factors
beyond FCA US LLC’s control may prevent or stop SOS Call
system operation. These include, but are not limited to,
the following factors:
 The ignition key is in OFF position.
 The vehicle’s electrical systems are not intact. 
The vehicle battery loses power or becomes discon -
nected during a vehicle crash.
 The SOS Call system software and/or hardware is
damaged during a vehicle crash.
 LTE (voice/data) or 4G (data) coverage and/or GPS
signals are unavailable or obstructed.
 Network congestion.
 Weather conditions.
 Buildings, structures, geographic terrain, or tunnels.
If your vehicle loses battery power for any reason
(including during or after an accident), the SOS Call
system, among other vehicle systems, will not operate.
Requirements
 This feature is available only on vehicles sold in the US
or Canada.
 Vehicle must be properly equipped with the SiriusXM
Guardian™ connected services. Vehicle must be regis -
tered with SiriusXM Guardian™ and have an active
subscription that includes the applicable feature.
 Vehicle must have an operable LTE (voice/data) or 4G
(data) network connection compatible with your device.
 Vehicle must be powered in the ON/RUN or ACC (Acces -
sory) position with a properly functioning electrical
system.
WARNING!
 Never place anything on or near the vehicle’s LTE
(voice/data) or 4G (data) and GPS antennas. You
could prevent LTE (voice/data) or 4G (data) and GPS
signal reception, which can prevent your vehicle from
placing an emergency call.
Do not add any aftermarket electrical equipment to
the vehicle’s electrical system. This may prevent your
vehicle from sending a signal to initiate an emer -
gency call. To avoid interference that can cause the
SOS Call system to fail, never add aftermarket equip -
ment (e.g., two-way mobile radio, CB radio, data
recorder, etc.) to your vehicle’s electrical system or
modify the antennas on your vehicle. IF YOUR
VEHICLE LOSES POWER FOR ANY REASON
(INCLUDING DURING OR AFTER AN ACCIDENT),
NEITHER THE VEHICLE BRANDED APPS NOR THE
SIRIUSXM GUARDIAN™ CONNECTED SERVICES WILL
OPERATE.
 The Occupant Restraint Controller (ORC) turns on the
Air Bag Warning Light on the instrument panel if a
malfunction in any part of the air bag system is
detected. If the Air Bag Warning Light is illuminated,
the air bag system may not be working properly and
the SOS Call system may not be able to send a signal
to the SiriusXM Guardian™ Customer Care center. If
the Air Bag Warning Light is illuminated, have an
authorized dealer service your vehicle immediately.
 Ignoring the Rearview Mirror Light could mean you
will not have SOS Call services if needed. If the Rear -
view Mirror Light is illuminated, have an authorized
dealer service the SOS Call system immediately.
