2012 JEEP GRAND CHEROKEE engine

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.
Failure to use the driver and passenger seat
belts provided is a major cause of severe or
fatal injury. In a rollover crash, an unbelted
person is significantly more likely to die than a
person wearing a seat belt. Always buckle up.IMPORTANT NOTICEALL MATERIAL CONTAINED IN THIS PUBLI-

Removing Key Fob From IgnitionPlace the shift lever in PARK. Turn the Key Fob
to the OFF position and then remove the Key
Fob.
With the Keyless Enter-N-Go feature, the EVIC
will display the ignition switch position “OFF/
ACC/RUN”. Refer to “Electronic Vehicle Infor-
mation Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.NOTE:
•
If you try to remove the Key Fob before
you place the shift lever in PARK, it may
become trapped temporarily in the igni-
tion switch. If this occurs, place the shift
lever in PARK, rotate the key to the right
slightly, then remove the Key Fob as de-
scribed. If a malfunction occurs, the sys-
tem may trap the key in the ignition switch
to warn you that this safety feature is
inoperable. The engine can be started and
stopped, but the Key Fob cannot be re-
moved until you obtain service.
• The power window switches, radio, power
sunroof (if equipped), and power outlets
will remain active for up to 10 minutes
after the ignition switch is turned to the
OFF position. Opening either front door
will cancel this feature. The time for this
feature is programmable. Refer to “Elec-
tronic Vehicle Information Center (EVIC)/
Personal Settings (Customer-Program-
mable Features)” in “Understanding Your
Instrument Panel” for further information.
CAUTION!
•If your vehicle battery becomes low or
dead, your Key Fob will become locked in
the ignition.
• Do not attempt to remove the Key Fob
while in this condition, damage could occur
to the Key Fob or ignition module. Only
remove the emergency key for locking and
unlocking the doors.
• Leave the Key Fob in the ignition and
either:
• Jump Start the vehicle.

WARNING!(Continued)
• Allowing children to be in a vehicle unat-
tended is dangerous for a number of rea-
sons. A child or others could be seriously or
fatally injured. Children should be warned
not to touch the parking brake, brake pedal
or the shift lever.
• Do not leave the key fob in or near the
vehicle, and do not leave Keyless Enter-
N-Go in the ACC or ON/RUN mode. A child
could operate power windows, other con-
trols, or move the vehicle.
• Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
CAUTION!
An unlocked car is an invitation to thieves.
Always remove Key Fob from the ignition and
lock all doors when leaving the vehicle unat-
tended.
Key-In-Ignition ReminderOpening the driver’s door when the Key Fob is
in the ignition and the ignition switch position is
OFF or ACC, sounds a signal to remind you to
remove the Key Fob.
NOTE:
The Key-In-Ignition reminder only sounds
when the Key Fob is placed in the OFF or
ACC ignition position.
With the Keyless Enter-N-Go feature, opening
the driver’s door when the vehicle’s ignition
switch is placed in ACC or ON/RUN (engine
stopped) will cause the reminder chime to
sound. Refer to “Starting Procedures” in “Start-
ing And Operating” for further information.
STEERING WHEEL LOCK — IF
EQUIPPED
Your vehicle may be equipped with a passive
electronic steering wheel lock. This lock pre-
vents steering the vehicle without the ignition
key. The steering wheel lock has six positions
(one every 60 degrees). If the steering wheel is
moved to one of these six position with the key
in the off positions, the steering wheel will lock.
To Manually Lock The Steering
Wheel
With the engine running, rotate the steering
wheel one-half revolution, turn off the engine
and remove the key. Turn the steering wheel
slightly in either direction until the lock en-
gages.
To Release The Steering Wheel LockCycle the ignition and start the engine.
NOTE:
If you turned the wheel to the right to engage
the lock, you must turn the wheel slightly to
the right to disengage it. If you turned the
wheel to the left to engage the lock, turn the
wheel slightly to the left to disengage it.
SENTRY KEYThe Sentry Key Immobilizer system prevents
unauthorized 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.
14

The system uses the factory-mated Key Fob
with Remote Keyless Entry (RKE) transmitter
and Wireless Ignition Node (WIN) to prevent
unauthorized vehicle operation. Therefore, only
Key Fobs that are programmed to the vehicle
can be used to start and operate the vehicle.
The system will shut the engine off in two
seconds if an invalid Key Fob is used to start
the engine.
After turning the ignition switch to 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 Key Fob 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 electronics. Should this occur,
have the vehicle serviced as soon as possible
by an authorized dealer.CAUTION!
The Sentry KeyImmobilizer system is not
compatible with some after-market remote
starting systems. Use of these systems may
result in vehicle starting problems and loss of
security protection.
All of the Key Fobs provided with your new
vehicle have been programmed to the vehicle
electronics.
Replacement Keys
NOTE:
Only Key Fobs that are programmed to the
vehicle electronics can be used to start and
operate the vehicle. Once a Key Fob is
programmed to a vehicle, it cannot be pro-
grammed to any other vehicle.
CAUTION!
• Always remove the Key Fobs from the
vehicle and lock all doors when leaving the
vehicle unattended.
(Continued)
CAUTION!(Continued)
• With Keyless Enter-N-Go, always remem-
ber to place the ignition in OFF.
At the time of purchase, the original owner is
provided with a four-digit Personal Identifica-
tion Number (PIN). Keep the PIN in a secure
location. This number is required for authorized
dealer replacement of Key Fobs. Duplication of
Key Fobs may be performed at an authorized
dealer.
NOTE:
When having the Sentry Key Immobilizer
system serviced, bring all vehicle ignition
keys with you to an authorized dealer.
Customer Key ProgrammingProgramming Key Fobs or RKE transmitters
may be performed at an authorized dealer.
General InformationThe Sentry Key operates on a carrier fre-
quency of 433.92 MHz. The Sentry Key Immo-
bilizer system will be used in the following
European countries, which apply Directive
1999/5/EC: Austria, Belgium, Czech Republic,

especially applies to children. The side curtain
air bag 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 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 re-
sponse to impact events.
Enhanced Accident Response System
In the event of an impact causing air bag
deployment, if the communication network re-
mains 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 Advanced Front Air Bags are designed to
deflate immediately after deployment.
NOTE:
Front and/or side air bags will not deploy in
all collisions. This does not mean some-
thing is wrong with the air bag system.
If you do have a collision which deploys the air
bags, any or all of the following may occur:
• The nylon air bag material may sometimes
cause abrasions and/or skin reddening to
the driver and front passenger as the air
bags deploy and unfold. The abrasions are
similar to friction rope burns or those you
might get sliding along a carpet or gymna-
sium floor. They are not caused by contact
with chemicals. They are not permanent and normally heal quickly. However, if you
haven’t healed significantly within a few
days, or if you have any blistering, see your
doctor immediately.
• As the air bags deflate, you may see some
smoke-like particles. The particles are a nor-
mal by-product of the process that gener-
ates the non-toxic gas used for air bag
inflation. These airborne particles may irri-
tate the skin, eyes, nose, or throat. If you
have skin or eye irritation, rinse the area with
cool water. For nose or throat irritation, move
to fresh air. If the irritation continues, see your
doctor. If these particles settle on your cloth-
ing, follow the garment manufacturer’s in-
structions for cleaning.
Do not drive your vehicle after the air bags have
deployed. If you are involved in another colli-
sion, the air bags will not be in place to protect
you.

WARNING!
•An incorrectly anchored tether strap could
lead to increased head motion and possible
injury to the child. Use only the anchor
positions directly behind the child seat to
secure a child restraint top tether strap.
• Do not use the cargo tie downs located on
the load floor. Improper usage of the tether
can lead to a failure of an infant or child
restraint. The child could be badly injured
or killed. 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 passen-
ger during panic braking or in an accident. 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 accel-
eration in low gear can be detrimental 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 “Main-
taining Your Vehicle”. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE
USED.
A new engine may consume some oil during its
first few thousand miles (kilometers) of opera-
tion. This should be considered a normal part
of the break-in and not interpreted as an indi-
cation of difficulty.
Additional Requirements For Diesel
Engine — If Equipped
During the first 1500 km avoid heavy loads, e.g.
driving at full throttle. Do not exceed 2/3 of the
maximum permissible engine speed for each
gear. Change gear in good time. Do not shift
down a gear manually in order to brake.
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 uncon-
scious 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 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.
If you are required to drive with the trunk/liftgate
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.
The best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained 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 misposi-
tioned 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.
Safety Checks You Should Make
Inside The Vehicle
Seat Belts
Inspect the belt system periodically, checking
for cuts, frays, and loose parts. Damaged parts
must be replaced immediately. Do not disas-
semble or modify the system.
Front seat belt assemblies must be replaced
after a collision. Rear seat belt assemblies must
be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing,
etc.). If there is any question regarding belt or
retractor condition, replace the belt.
Air Bag Warning Light
The light should come on and remain on for four
to eight seconds as a bulb check when the
ignition switch is first turned ON. If the light is
not lit during starting, see your authorized
dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by
an authorized dealer.
