2013 JEEP GRAND CHEROKEE engine overheat

NOTE:
Press theESC Offswitch (if necessary), to
place the Electronic Stability Control (ESC)
system in Partial Off mode, before rocking
the vehicle. Refer to “Electronic Brake Con-
trol” in “Starting And Operating” for further
information. Once the vehicle has been
freed, press the ESC Offswitch again to
restore ESC On mode.
CAUTION!
Racing the engine or spinning the wheels
may lead to transmission overheating and
failure. Allow the engine to idle with the
transmission in NEUTRAL for at least one
minute after every five rocking-motion
cycles. This will minimize overheating and
reduce the risk of transmission failure during
prolonged efforts to free a stuck vehicle.
CAUTION!
•
When “rocking” a stuck vehicle by shifting
between DRIVE and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or
drivetrain damage may result.
•Revving the engine or spinning the wheels
too fast may lead to transmission over-
heating and failure. It can also damage the
tires. Do not spin the wheels above
30 mph (48 km/h) while in gear (no trans-
mission shifting occurring).
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause damage, or even failure,
of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle’s
(Continued)
WARNING!(Continued)
wheels faster than 30 mph (48 km/h) or for
longer than 30 seconds continuously without
stopping when you are stuck and do not let
anyone near a spinning wheel, no matter
what the speed.
TOW EYES
Your vehicle is equipped with tow eyes, which
are mounted in the front and the rear.
CAUTION!
Tow eyes are for emergency use only, to
rescue a vehicle stranded off road. Do not use
tow eyes for tow truck hookup or highway
towing. You could damage your vehicle. Tow
straps are recommended when towing the
vehicle; chains may cause vehicle damage.

WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite
and burn you. Care must be exercised when
filling or working around the washer solution.
Exhaust SystemThe best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained engine exhaust system.
If you notice a change in the sound of the
exhaust system; or if the exhaust fumes can be
detected inside the vehicle; or when the under-
side or rear of the vehicle is damaged; have an
authorized technician inspect the complete ex-
haust system and adjacent body areas for bro-
ken, damaged, deteriorated, or mispositioned
parts. Open seams or loose connections could
permit exhaust fumes to seep into the passen-
ger compartment. In addition, have the exhaust
system inspected each time the vehicle is
raised for lubrication or oil change. Replace as
required.
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, refer to
“Safety Tips/Exhaust Gas” in “Things To
Know Before Starting Your Vehicle” for
further information.
• A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do
not park or operate your vehicle in areas
where your exhaust system can contact
anything that can burn.CAUTION!
•The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as
an emissions control device and may seri-
ously reduce engine performance and
cause serious damage to the engine.
• Damage to the catalytic converter can
result if your vehicle is not kept in proper
operating condition. In the event of engine
malfunction, particularly involving engine
misfire or other apparent loss of perfor-
mance, have your vehicle serviced
promptly. Continued operation of your ve-
hicle with a severe malfunction could
cause the converter to overheat, resulting
in possible damage to the converter and
vehicle.
Under normal operating conditions, the catalytic
converter will not require maintenance. How-
ever, it is important to keep the engine properly
tuned to assure proper catalyst operation and
prevent possible catalyst damage.

Please note that it is the owner’s responsibility to
maintain the proper level of protection against
freezing according to the temperatures occurring
in the area where the vehicle is operated.
NOTE:
Mixing engine coolant (antifreeze) types is
not recommended and can result in cooling
system damage. Drain, flush, and refill as
soon as possible to avoid damage if coolant
types are mixed in an emergency.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss
of engine coolant (antifreeze), and to ensure
that engine coolant (antifreeze) will return to the
radiator from the coolant recovery tank.
The cap should be inspected and cleaned if
there is any accumulation of foreign material on
the sealing surfaces.
WARNING!
•The warning words “DO NOT OPEN HOT”
on the cooling system pressure cap are a
safety precaution. Never add engine cool-
ant (antifreeze) when the engine is over-
heated. Do not loosen or remove the cap
to cool an overheated engine. Heat causes
pressure to build up in the cooling system.
To prevent scalding or injury, do not re-
move the pressure cap while the system is
hot or under pressure.
• Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant (an-
tifreeze) is a regulated substance requiring
proper disposal. Check with your local authori-
ties to determine the disposal rules for your
community. To prevent ingestion by animals or
children, do not store ethylene glycol-based
engine coolant (antifreeze) in open containers or allow it to remain in puddles on the ground. If
ingested by a child or pet, seek emergency
assistance immediately. Clean up any ground
spills immediately.
Coolant Level
The coolant bottle provides a quick visual
method for determining that the coolant level is
adequate. With the engine OFF and cold, the
level of the engine coolant (antifreeze) in the
bottle should be between the ranges indicated
on the bottle.
The radiator normally remains completely full,
so there is no need to remove the radiator cap
unless checking for engine coolant (antifreeze)
freeze point or replacing coolant. Advise your
service attendant of this. As long as the engine
operating temperature is satisfactory, the cool-
ant bottle need only be checked once a month.
When additional engine coolant (antifreeze) is
needed to maintain the proper level, only OAT
coolant that meets the requirements of Chrysler
Material Standard MS-12106 should be added
to the coolant bottle. Do not overfill.
