2016 JEEP GRAND CHEROKEE service

This Owner’s Manual has been prepared with the assis-
tance of service and engineering specialists to acquaint
you with the operation and maintenance of your vehicle.
It is supplemented by Warranty Information, and various
customer-oriented documents. Please take the time to
read these publications carefully. Following the instruc-
tions and recommendations in this manual will help
assure safe and enjoyable operation of your vehicle.
NOTE: After reviewing the owner information, it
should be stored in the vehicle for convenient referenc-
ing and remain with the vehicle when sold.
When it comes to service, remember that your authorized
dealer knows your Jeep® vehicle best, has factory-trained
technicians and genuine MOPAR® parts, and cares about
your satisfaction.ROLLOVER WARNING
Utility vehicles have a significantly higher rollover rate
than other types of vehicles. This vehicle has a higher
ground clearance and a higher center of gravity than
many passenger vehicles. It is capable of performing
better in a wide variety of off-road applications. Driven
in an unsafe manner, all vehicles can go out of control.
Because of the higher center of gravity, if this vehicle is
out of control it may roll over while some other vehicles
may not.
Do not attempt sharp turns, abrupt maneuvers, or other
unsafe driving actions that can cause loss of vehicle
control. Failure to operate this vehicle safely may result
in a collision, rollover of the vehicle, and severe or fatal
injury. Drive carefully.1
INTRODUCTION 5

SENTRY KEY
The Sentry Key Immobilizer System prevents unauthor-
ized vehicle operation by disabling the engine. The
system does not need to be armed or activated. Operation
is automatic, regardless of whether the vehicle is locked
or unlocked.
The system uses a RKE Key Fob, an Ignition Node
Module, Keyless Push Button Ignition and a RF receiver
to prevent unauthorized vehicle operation. Therefore,
only RKE Key Fobs that are programmed to the vehicle
can be used to start and operate the vehicle. The system
will not allow the engine to crank if an invalid RKE Key
Fob is used to start and operate the vehicle. The system
will shut the engine off in two seconds if an invalid RKE
Key Fob is used to start the engine.
NOTE:A RKE Key Fob that has not been programmed is
also considered an invalid key. During normal operation, after placing the keyless igni-
tion in the ON/RUN position, the Vehicle Security Light
will turn on for three seconds for a bulb check. If the light
remains on after the bulb check, it indicates that there is
a problem with the electronics. In addition, if the light
begins to flash after the bulb check, it indicates that
someone used an invalid RKE Key Fob to try to start the
engine. Either of these conditions will result in the engine
being shut off after two seconds.
If the Vehicle Security Light turns on during normal
vehicle operation (vehicle running for longer than 10
seconds), it indicates that there is a fault in the electron-
ics. Should this occur, have the vehicle serviced as soon
as possible by an authorized dealer.
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt and allow it
to retract completely to disengage the Automatic Locking
Mode and activate the vehicle sensitive (emergency)
locking mode.
WARNING!
•The seat belt assembly must be replaced if the
switchable Automatic Locking Retractor (ALR) fea-
ture or any other seat belt function is not working
properly when checked according to the proce-
dures in the Service Manual.
• Failure to replace the seat belt assembly could
increase the risk of injury in collisions.
• Do not use the Automatic Locking Mode to restrain
occupants who are wearing the seat belt or children

only used to install rear-facing or forward-facing
child restraints that have a harness for restraining
the child.
Supplemental Active Head Restraints (AHR)
These head restraints are passive, deployable compo-
nents, and vehicles with this equipment cannot be readily
identified by any markings, only through visual inspec-
tion of the head restraint. The head restraint will be split
in two halves, with the front half being soft foam and
trim, the back half being decorative plastic.
How The Active Head Restraints (AHR) Work
The Occupant Restraint Controller (ORC) determines
whether the severity, or type of rear impact will require
the Active Head Restraints (AHR) to deploy. If a rear
impact requires deployment, both the driver and front
passenger seat AHRs will be deployed.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 65

Do not drive your vehicle after the air bags have de-
ployed. 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 pretensioners cannot
protect you in another collision. Have the air bags,
seat belt pretensioners, and the seat belt retractor
assemblies replaced by an authorized dealer imme-
diately. Also, have the Occupant 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 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 hazard light button is pressed. The hazard
lights can be deactivated by pressing the hazard light
button.
• Turn on the interior lights, which remain on as long as
the battery has power.
• Unlock the power door locks.

While the air bag system is designed to be maintenance
free, 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.WARNING!
Ignoring the Air Bag Warning Light in your instru-
ment panel could mean you won’t have the air bags
to protect you in a collision. If the light does not come
on as a bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if it comes
on as you drive, have an authorized dealer service the
air bag system immediately.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light is detected, which could affect the Supplemental Restraint
System (“SRS”), the Redundant Air Bag Warn-
ing Light will illuminate on the instrument
panel. The Redundant Air Bag Warning Light
will stay on until the fault is cleared. In addition, a single
chime will sound to alert you that the Redundant Air Bag
Warning Light has come on and a fault has been detected.
