2014 JEEP GRAND CHEROKEE engine

enough force to injure you if you are not belted and
seated properly, or if items are positioned in the area
where the SABIC inflates. This especially applies to
children. The SABIC is only about 3-1/2 in (9 cm) thick
when it is inflated.
Because air bag sensors estimate deceleration over time,
vehicle speed and damage are not good indicators of
whether or not an air bag should have deployed.
NOTE:In a rollover the pretensioners and/or SAB and
SABIC air bags, and driver/passenger knee air bags may
deploy on both sides of the vehicle.
Front And Side Impact Sensors
In front and side impacts, impact sensors can aid the
ORC in determining appropriate response to impact
events.
Enhanced Accident Response System
In the event of an impact causing air bag 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.

NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. The air bags may
not be ready to inflate for your protection. Promptly
check the fuse block for blown fuses. Refer to “Fuses” in
“Maintaining Your Vehicle” for the proper air bag fuses.
See your authorized dealer if the fuse is good.
Event Data Recorder (EDR)
This vehicle is equipped with an event data recorder
(EDR). The main purpose of an EDR is to record, in
certain crash or near crash-like situations, such as an air
bag deployment or hitting a road obstacle, data that will
assist in understanding how a vehicle’s systems per-
formed. The EDR is designed to record data related to
vehicle dynamics and safety systems for a short period of
time, typically 30 seconds or less. The EDR in this vehicle
is designed to record such data as:
• How various systems in your vehicle were operating; •
Whether or not the driver and passenger safety belts
were buckled/fastened;
• How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better understanding of
the circumstances in which crashes and injuries occur.
NOTE: EDR data are recorded by your vehicle only if a
non-trivial crash situation occurs; no data are recorded by
the EDR under normal driving conditions and no per-
sonal data (e.g., name, gender, age, and crash location)
are recorded. However, other parties, such as law en-
forcement, could combine the EDR data with the type of
personally identifying data routinely acquired during a
crash investigation.
To read data recorded by an EDR, special equipment is
required, and access to the vehicle or the EDR is needed.

WARNING!
The top tether anchorages are not visible until the
gap panel is folded down. Do not use the visible
cargo tie down hooks, located on the floor behind the
seats, to attach a child restraint tether anchor.
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
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (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.
Wide-open throttle acceleration in low gear can be detri-
mental and should be avoided.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur. For
the recommended viscosity and quality grades, refer to
“Maintenance Procedures” in “Maintaining Your Ve-
hicle”.
106 THINGS TO KNOW BEFORE STARTING 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.
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.
• 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.
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.
(Continued)
WARNING! (Continued)
•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 positive 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.

provide a boosted heat level during the first four minutes
of operation. Then, the heat output will drop to the
normal HIGH-level. If the HIGH-level setting is selected,
the system will automatically switch to LOW-level after
approximately 60 minutes of continuous operation. At
that time, the display will change from HIGH to LOW,
indicating the change. The LOW-level setting will turn
OFF automatically after approximately 45 minutes.
NOTE: 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 programed to come on during a
remote start.
This feature can be programmed through the Uconnect®
