2008 JEEP COMPASS coolant

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 (bent retractor, torn
webbing, etc. If there is any question regarding belt or
retractor condition, replace the belt.
Airbag Light
The light should come on and remain on for 6 to 8
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 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.
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 wheel nuts for tightness, and tires (includ-
ing 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 area under vehicle after overnight parking for fuel,
engine coolant, oil or other fluid leaks. Also, if gasoline
fumes are detected or fuel, power steering fluid, trans-
mission fluid or brake fluid leaks are suspected, the cause
should be located and corrected immediately.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 67
2

13. Engine Coolant Temperature Warning Light
This light warns of an overheated engine condi-
tion. If the engine is critically hot, a warning chime
will sound 10 times. After the chime turns off, the
engine will still be critically hot until the light goes out.
14. Brake System Warning Light
This light monitors various brake functions, in-
cluding brake fluid level and parking brake appli-
cation. If the brake light turns on, it may indicate that the
parking brake is applied, there is a low brake fluid level
or there is a problem with the anti-lock brake system.
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. Failure of either half of the dual brake system is
indicated by the Brake Warning Light which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.NOTE:The light may flash momentarily during sharp
cornering maneuvers which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.
WARNING!
Driving a vehicle with the brake light on is danger-
ous. Part of the brake system may have failed. It will
take longer to stop the vehicle. You could have an
accident. Have the vehicle checked immediately.
Vehicles equipped with Anti-Lock brakes (ABS), are also
equipped with Electronic Brake Force Distribution (EBD).

Window Fogging
Vehicle side windows tend to fog on the inside in mild
rainy or humid weather. To clear the windows, set mode
to the mix or defrost position. Direct the panel outlets
toward the side windows. Do not use recirculate without
A/C for long periods as fogging may occur.
Interior fogging on the windshield can be quickly re-
moved by using the defrost position.
If the fogging problem persists, clean the inside window
surfaces. The cause of undue fogging may be dirt collect-
ing on the inside surface of the glass.
NOTE:In cold weather, the use of the recircu-
late position will cause windows to fog on the
inside because of moisture build up inside the
vehicle. For maximum defogging, press the
recirculation button until recirculate is off.
Summer Operation
Air conditioned vehicles must be protected with a high-
quality antifreeze coolant to provide proper corrosion
protection and to raise the boiling point of the coolant for
protection against overheating. A 50% concentration is
recommended.
Outside Air Intake
When operating the system during the winter months,
make sure the air intake, directly in front of the wind-
shield, is free of ice, slush, snow or other obstructions
such as leaves. Leaves collected in the air-intake plenum
may reduce air flow and plug the plenum water drains.
The blower air will heat faster in cold weather if you use
only a low blower speed for the first few minutes of
vehicle operation.

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 Section 7, Maintenance, 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!
²Being 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.
²The 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.
298 WHAT TO DO IN EMERGENCIES

when the underside or rear of the vehicle is damaged;
have a competent technician inspect the complete ex-
haust system and adjacent body areas for broken, dam-
aged, 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 an oil
change or lubrication. 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 Exhaust Gas in the Safety Tips section of this
manual.
Cooling System
WARNING!
²When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition
switch to the OFF position. The fan is temperature
controlled and can start at any time the ignition
switch is in the ON position.
²You 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, don't 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 coolant is dirty or rusty in appearance, the
system should be drained, flushed and refilled with fresh
coolant. 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 Ð Drain, Flush and Refill
At the intervals shown in the ªMaintenance Schedule,º
the system should be drained, flushed and refilled. Refer
to Section 8 of this manual.
If the solution 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
antifreeze solution.
Selection Of Coolant
Use only the manufacturers recommended coolant, refer
to ª Fluids, Lubricants and Genuine Partsº for correct
coolant type.
330 MAINTAINING YOUR VEHICLE

CAUTION!
Mixing of coolants other than specified Hybrid Or-
ganic Additive Technology (HOAT) engine coolants,
may result in engine damage and may decrease
corrosion protection. If a non-HOAT coolant is intro-
duced into the cooling system in an emergency, it
should be replaced with the specified coolant as soon
as possible.
Do not use plain water alone or alcohol base engine
coolant (antifreeze) products. Do not use additional
rust inhibitors or antirust products, as they may not
be compatible with the radiator engine coolant and
may plug the radiator.
This vehicle has not been designed for use with
Propylene Glycol based coolants. Use of Propylene
Glycol based coolants is not recommended.
Adding Coolant
Your vehicle has been built with an improved engine
coolant that allows extended maintenance intervals. This
coolant can be used up to 5 Years or 100,000 miles before
replacement. To prevent reducing this extended mainte-
nance period, it is important that you use the same
coolant throughout the life of your vehicle. Please review
these recommendations for using Hybrid Organic Addi-
tive Technology (HOAT) coolant.
When adding coolant, a minimum solution of 50% rec-
ommended Mopar Antifreeze/ Coolant 5 Year/100,000
Mile Formula HOAT (Hybrid Organic Additive Technol-
ogy), or equivalent, in water should be used. Use higher
concentrations (not to exceed 70%) if temperatures below
234ÉF (237ÉC ) are anticipated.
Use only high purity water such as distilled or deionized
water when mixing the water/engine coolant solution.
MAINTAINING YOUR VEHICLE 331

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 coolant types will decrease the life of the
engine coolant and will require more frequent coolant
changes.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
coolant, and to insure that coolant 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!
²The warning words ªDO NOT OPEN HOTº on
the cooling system pressure cap are a safety pre-
caution. Never add coolant 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 scald-
ing or injury, do not remove the pressure cap while
the system is hot or under pressure.
²Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or en-
gine damage may result.
