2009 JEEP PATRIOT coolant temperature

The light also will turn on when the parking brake is
applied with the ignition switch in the ON position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
15. Transmission Temperature Warning Light
During sustained high speed driving on hot
days, the automatic transaxle oil may become
too hot. If this happens, the transmission over-
heat indicator light will come on and the
vehicle will slow slightly until the automatic transaxle
cools down enough to allow a return to the requested
speed. If the high speed is maintained, the overheating
will reoccur as before in a cyclic fashion.
16. Vehicle Security Light — If Equipped
This light will flash at a fast rate for approxi-
mately 16 seconds, when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.17. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If temperature gauge reads “H”
pull over and stop the vehicle. Idle the vehicle with
the air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the “H” and you hear continuous chimes, turn the
engine off immediately, and call an authorized deal-
ership for service.
172 UNDERSTANDING YOUR INSTRUMENT PANEL

When adding engine coolant (antifreeze), a minimum
solution of 50% recommended MOPARAntifreeze/
Coolant 5 Year/100,000 Mile Formula HOAT (Hybrid
Organic Additive Technology), or equivalent, in water
should be used. Use higher concentrations (not to exceed
70%) if temperatures below34°F (37°C) are antici-
pated.
Use only high purity water such as distilled or deionized
water when mixing the water/engine coolant (antifreeze)
solution. The use of lower quality water will reduce the
amount of corrosion protection in the engine cooling system.
Please note that it is the owner’s responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
NOTE:Mixing engine coolant (antifreeze) types will
decrease the life of the engine coolant (antifreeze) and
will require more frequent coolant changes.
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 bottle.
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 coolant (antifreeze) when the
engine is overheated. 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 remove the pres-
sure cap while the system is hot or under pressure.

WARNING! (Continued)
•Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or en-
gine damage may result.
Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant (antifreeze) is
a regulated substance requiring proper disposal. Check
with your local authorities to determine the disposal
rules for your community. To prevent ingestion by ani-
mals 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, contact a physician 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 idling and warm to normal operating tempera-
ture, the level of the engine coolant (antifreeze) in the
bottle should be between the “ADD” and “FULL” lines
shown on the bottle.
The radiator normally remains completely full, so there is
no need to remove the radiator cap unless checking for
the coolant freeze point or replacing the engine coolant
(antifreeze). Advise your service attendant of this. As
long as the engine operating temperature is satisfactory,
the coolant bottle need only be checked once a month.
When additional engine coolant (antifreeze) is needed to
maintain the proper level, it should be added to the
coolant bottle. Do not overfill.
