2008 JEEP COMPASS battery

Your vehicle has a simple ignition key actuated test,
which you can use prior to going to the test station. To
check if your vehicle's OBD system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see your MIL symbol come on as part of a normal
bulb check.
5. Approximately 15 seconds later, one of two things will
happen:
a. The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn off theignition key or start the engine. This means that your
vehicle's OBD system isnot readyand you shouldnot
proceed to the I/M station.
b. The MIL will not flash at all and will remain fully
illuminated until you turn off the ignition key or start
the engine. This means that your vehicle's OBD system
isreadyand you can proceed to the I/M station.
If your OBD system isnot ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD
system to update. A recheck with the above test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle's OBD system is
ready or not ready, if the MIL symbol is illuminated
during normal vehicle operation, you should have your

Maintenance-Free Battery
You will never have to add water, nor is periodic main-
tenance required.
CAUTION!
When servicing the battery, always reinstall the bat-
tery thermowrap. The thermowrap provides battery
heat protection and will extend overall battery life.
Failure to reinstall the thermowrap can result in
evaporative loss of the battery fluid.
WARNING!
Battery fluid is a corrosive acid solution and can burn
or even blind you. Don't allow battery fluid to
contact your eyes, skin or clothing. Don't lean over a
battery when attaching clamps. If acid splashes in
eyes or on skin, flush the area immediately with
large amounts of water.
Battery gas is flammable and explosive. Keep flame
or sparks away from the battery. Don't use a booster
battery or any other booster source with an output
greater than 12 volts. Don't allow cable clamps to
touch each other.
Battery posts, terminals and related accessories con-
tain lead and lead compounds. Wash hands after
handling.
324 MAINTAINING YOUR VEHICLE

CAUTION!
It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to the
negative post. Battery posts are marked positive (+)
and negative (-) and identified on the battery case.
Cable clamps should be tight on the terminal posts
and free of corrosion. Apply grease to posts and
clamps after tightening.
If a ªfast chargerº is used while the battery is in the
vehicle, disconnect both vehicle battery cables before
connecting the charger to battery. Do not use a ªfast
chargerº to provide starting voltage as battery dam-
age can result.
Air Conditioner Maintenance
For best possible performance, your air conditioner
should be checked and serviced by an Authorized Dealer
at the start of each warm season. This service should
include cleaning of the condenser fins and a performance
test. Drive belt tension should also be checked at this
time.

At Each Stop for Fuel
²Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
²Check the windshield washer solvent and add if
required.
Once a Month
²Check tire pressure and look for unusual wear or
damage.
²Inspect the battery and clean and tighten the terminals
as required.
²Check the fluid levels of coolant reservoir, brake
master cylinder, power steering and transmission and
add as needed.
²Check all lights and other electrical items for correct
operation.
At Each Oil Change
²Change the engine oil filter.
²Inspect the brake hoses and lines.
²Check the Manual Transmission fluid level.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
