engine coolant JEEP COMPASS 2009 1.G Owners Manual

Airbag Warning Light
The light should come on and remain on for six to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the LED is not lit during starting, have it
checked. If the light stays on, flickers, or comes on while
driving, have the system checked by an authorized
dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is
inoperable.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect tread and sidewall for cuts or
cracks. Check the wheel nuts for tightness. Check the
tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check the area under the vehicle after overnight parking
for fuel, engine coolant, oil or other fluid leaks. Also, if
gasoline fumes are detected or fuel, power steering fluid,
transmission fluid or brake fluid leaks are suspected, the
cause should be located and corrected immediately.
70 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 Indicator
During sustained high speed driving on hot
days, the automatic transmission oil may be-
come too hot. If this happens, the transmission
overheat indicator light will come on and the
vehicle will slow slightly until the automatic transmis-
sion cools down enough to allow a return to the re-
quested 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.

WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, refer to “Maintenance”, Section 7 of
this manual. Follow the warnings under the “Cooling
System Pressure Cap” paragraph.
AUTOMATIC TRANSAXLE OVERHEATING
During sustained high speed driving or trailer towing up
long grades on hot days, the automatic transaxle oil may
become too hot.
If this happens, the transmission overheat in-
dicator light will come on, and the vehicle will
slow slightly until the automatic transaxle
cools down enough to allow a return to therequested speed. If the high speed is maintained, the
overheating will reoccur, as before, in a cyclic fashion.
JACKING AND TIRE CHANGING
WARNING!
•Being under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle is on a jack. If you
need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
•The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or
slippery areas.

WARNING! (Continued)
•You or others can be badly burned by hot coolant
or steam from your radiator. If you see or hear
steam coming from under the hood, do not open
the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap
when the radiator is hot.
Coolant Checks
Check engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty or
rusty in appearance, the system should be drained,
flushed and refilled with fresh engine coolant (anti-
freeze). Check the front of the A/C condenser for any
accumulation of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically down the
face of the condenser.Check the coolant recovery bottle tubing for brittle rub-
ber, cracking, tears, cuts and tightness of the connection
at the bottle and radiator. Inspect the entire system for
leaks.
Cooling System — Drain, Flush And Refill
Refer to the “Maintenance Schedule” in Section 8 for
proper maintenance intervals.
If the engine coolant (antifreeze) is dirty or contains a
considerable amount of sediment, clean and flush with a
reliable cooling system cleaner. Follow with a thorough
rinsing to remove all deposits and chemicals. Properly
dispose of old engine coolant (antifreeze).
Selection Of Coolant
Refer to “Fluids, Lubricants, and Genuine Parts” in this
section for the correct fluid type.

CAUTION!
•Mixing of engine coolant (antifreeze) other than
specified Hybrid Organic Additive Technology
(HOAT) engine coolant (antifreeze), may result in
engine damage and may decrease corrosion pro-
tection. If a non-HOAT engine coolant (antifreeze)
is introduced into the cooling system in an emer-
gency, it should be replaced with the specified
engine coolant (antifreeze) as soon as possible.
•Do not use water alone or alcohol based engine
coolant (antifreeze) products. Do not use addi-
tional rust inhibitors or antirust products, as they
may not be compatible with the radiator engine
coolant and may plug the radiator.
(Continued)
CAUTION! (Continued)
•This vehicle has not been designed for use with
Propylene Glycol based engine coolant (anti-
freeze). Use of Propylene Glycol based engine
coolant (antifreeze) is not recommended.
Adding Coolant
Your vehicle has been built with an improved engine
coolant (antifreeze) that allows extended maintenance
intervals. This engine coolant (antifreeze) can be used up
to five years or 102,000 miles (170 000 km) before
replacement. To prevent reducing this extended mainte-
nance period, it is important that you use the same
engine coolant (antifreeze) throughout the life of your
vehicle. Please review these recommendations for using
Hybrid Organic Additive Technology (HOAT) engine
coolant (antifreeze).
360 MAINTAINING YOUR VEHICLE

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.
•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 (antifreeze) is
a regulated substance requiring proper disposal. Check
with your local authorities to determine the disposalrules 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.
362 MAINTAINING YOUR VEHICLE

When additional engine coolant (antifreeze) is needed to
maintain the proper level, it should be added to the
coolant bottle. Do not overfill.
Points to Remember
NOTE:When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is nor-
mally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot engine
coolant (antifreeze) to enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
•Do not overfill the coolant recovery bottle.
•Check the coolant freeze point in the radiator and in the
coolant recovery bottle. If engine coolant (antifreeze)needs to be added, the contents of the coolant recovery
bottle must also be protected against freezing.
•If frequent engine coolant (antifreeze) additions are
required, or if the level in the coolant recovery bottle
does not drop when the engine cools, the cooling
system should be pressure tested for leaks.
•Maintain engine coolant (antifreeze) concentration at
50% HOAT engine coolant (antifreeze) (minimum)
and distilled water for proper corrosion protection of
your engine which contains aluminum components.
•Make sure that the radiator and coolant recovery
bottle overflow hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean also.
•Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
