2008 DODGE DURANGO ignition

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. If you crank or start the engine, you
will have to start this test over.
3. 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.
4. Approximately 15 seconds later, one of two things will
happen:
a. The MIL light will blink for approximately 5 sec-
onds and then remain on until the first engine crank orthe key is turned off. This means that your vehicle's
OBD system isnot readyand you shouldnotproceed
to the I/M station.
b. The MIL light will remain fully illuminated until the
first engine crank or the key is turned off. This means
that your vehicle's OBD system isreadyand you can
proceed to the I/M station.
If your OBD system isnot readyyou should see your
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

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 transmission 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.
Maintenance Free Battery
The top of the maintenance free battery is permanently
sealed. You will never have to add water, nor is periodic
maintenance required.

Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
FUSE BLOCK
CAUTION!
When 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 suggests a
problem in the circuit that must be corrected.NOTE:If you are leaving your vehicle dormant for
longer than 21 days you may want to take steps to protect
your battery. You may do this by disconnecting the
battery or by disconnecting the two ignition-off draw
(I.O.D.) fuses located in the Auxiliary Power Distribution
Center (PDC) located in the engine compartment. The
I.O.D. cavities include a snap-in retainer that allows the
fuse to be disconnected, without removing it from the
fuse block. Pressing the I.O.D. fuse back into the cavity
reconnects it.

VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle's battery:
²Disconnect the Ignition-Off Draw fuse (I.O.D.) fuse
located in the Power Distribution Center (PDC). The
I.O.D. cavity includes a snap-in retainer that allows the
fuse to be disconnected, without removing it from the
fuse block.
²The transfer case should be placed in the 4HI mode
and kept in this position to minimize the battery drain.
²As an alternative to the above steps you may discon-
nect the negative cable from the battery.
