2016 JEEP GRAND CHEROKEE Engine

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.

Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition must be changed
from the START or ON/RUN position to the OFF posi-
tion. Carefully check the vehicle for fuel leaks in the
engine compartment and on the ground near the engine
compartment and fuel tank before resetting the system
and starting the engine.
Air Bag Warning Light
The air bags must be ready to inflate for your protectionin a collision. The Occupant Restraint Control-
ler (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 placed 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.
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
80 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

diagnostics also record the nature of the malfunction.
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.

Transporting Pets
Air Bags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
a collision.
Pets should be restrained in the rear seat in pet harnesses
or pet carriers that are secured by seat belts.
ENGINE BREAK-IN RECOMMENDATIONS
For vehicles equipped with the 3.6L or 5.7L use the
following engine break-in recommendations:
A long break-in period is not required for the drivetrain
(engine, transmission, clutch, and rear axle) in your new
vehicle.
Drive moderately during the first 300 mi (500 km). After
the initial 60 mi (100 km), speeds up to 50 or 55 mph
(80 or 90 km/h) are desirable.While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
However, wide-open throttle acceleration in low gear can
be detrimental and should be avoided.
The engine oil, transmission fluid, and axle lubricant
installed at the factory is high-quality and energy-
conserving. Oil, fluid, and lubricant changes should be
consistent with anticipated climate and conditions under
which vehicle operations will occur. For the recom-
mended viscosity and quality grades, refer to “Mainte-
nance Procedures” in “Maintaining Your Vehicle”.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.

NOTE:A new engine may consume some oil during its
first few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in and
not interpreted as an indication of difficulty. Please check
your oil level with the engine oil indicator often during
the break in period. Add oil as required.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE CARGO
AREA.
WARNING!
• Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
(Continued)
WARNING! (Continued)
•It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people
riding in these areas are more likely to be seriously
injured or killed.
• Do not allow people to ride in any area of your
vehicle that is not equipped with seats and seat
belts.
• Be sure everyone in your vehicle is in a seat and
using a seat belt properly.
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
(Continued)
110 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!(Continued)
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO),
follow these safety tips:
•Do not run the engine in a closed garage or in
confined areas any longer than needed to move
your vehicle in or out of the area.
•
If you are required to drive with the trunk/liftgate/
rear doors open, make sure that all windows are
closed and the climate control BLOWER switch is set
at high speed. DO NOT use the recirculation mode.
• If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling
controls to force outside air into the vehicle. Set the
blower at high speed. The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.

Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are suspected. The cause
should be located and corrected immediately.
114 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

If the HI-level setting is selected, the system will auto-
matically switch to LO-level after approximately 60 min-
utes of continuous operation. At that time, the display
will change from HI to LO, indicating the change. The
LO-level setting will turn OFF automatically after ap-
proximately 45 minutes.
NOTE:
•Once a heat setting is selected, heat will be felt within
two to five minutes.
• The engine must be running for the heated seats to
operate.
Vehicles Equipped With Remote Start
On models that are equipped with remote start, the
heated seats can be programmed to come on during a
remote start. This feature can be programmed through the Uconnect
system. Refer to “Uconnect Settings” in “Understanding
Your Instrument Panel” for further information.
WARNING!
•
Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, exhaus-
tion or other physical condition must exercise care
when using the seat heater. It may cause burns
even at low temperatures, especially if used for
long periods of time.
• Do not place anything on the seat or seatback that
insulates against heat, such as a blanket or cushion.
This may cause the seat heater to overheat. Sitting
in a seat that has been overheated could cause
serious burns due to the increased surface tempera-
ture of the seat.
