ignition CHRYSLER TOWN AND COUNTRY 2008 5.G Owners Manual

This vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if this vehicle's OBD II system is ready, you must
do the following:
1. Insert the 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 the ignition key to the ON
position, you will see the 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 OFFthe ignition key or start the engine. This means that the
vehicle's OBD II system isnot readyand you should
notproceed 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 the vehicle's OBD II
system isready,and you can proceed to the I/M
station.
If the OBD II system isnot ready,you should see an
authorized dealer or repair facility. If this vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive the vehicle
as you normally would in order for the OBD II system to
update. A recheck with the above test routine may then
indicate that the system is now ready.
Regardless of whether the vehicle's OBD II system is
ready or not ready, if the MIL is illuminated during
normal vehicle operation, you should have the vehicle

WARNING!
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.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may indicate severe
and abnormal catalyst overheating. If this occurs, the
vehicle should be stopped, the engine shut off and the
vehicle allowed to cool. Thereafter, service, including a
tune-up to manufacturer's specifications, should be ob-
tained immediately.To minimize the possibility of catalyst damage:²Do not shut off the engine or interrupt the ignition
when the transaxle is in gear and the vehicle is in
motion.
²Do not try to start engine by pushing or towing the
vehicle.
²Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idling or malfunctioning operating conditions.

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 anytime 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 the 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.
With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
coolant from the radiator drain cock. If the cap is sealing
properly, the engine coolant (antifreeze) will begin to

CAUTION!
²When installing the Integrated Power Module cover,
it is important to ensure the cover is properly
positioned and fully latched. Failure to do so may
allow water to get into the Integrated Power Mod-
ule, and possibly result in a electrical system failure.
²When replacing a blown fuse, it is important to use
only a fuse having the correct amperage rating. The
use of a fuse with a rating other than indicated may
result in a dangerous electrical system overload. If a
properly rated fuse continues to blow, it indicates a
problem in the circuit that must be corrected.
The Heated Mirrors, Lower Instrument Panel Power Outlet
and Removable Floor Console, when in the front position
are fused with self-resetting fuses that are only serviceable
by an authorized dealer. The power seats are fused by a 30Amp circuit breaker located under the driver's seat. The
Power Windows are fused by a 25 Amp circuit breaker
located under the instrument panel near the steering
column. If you experience temporary or permanent loss of
these systems, see your authorized dealer for service.
VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days you may want to take steps to protect your battery.
You may do the following:
²Remove the 20 Amp mini-fuse in the Integrated Power
Module labeled Ignition-Off Draw (IOD).
²Or, disconnect the negative cable from the battery.
²Anytime you store your vehicle, or keep it out of
service for two weeks or more, run the air conditioning
system at idle for about five minutes in the fresh air
and high blower setting. This will ensure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.
