2004 DODGE DURANGO service indicator

CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and driveability.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immediate
service is required.
25. Airbag Indicator
The indicator lights and remains lit for 6 to 8
seconds when the ignition is first turned ON. If
the light does not come on when the ignition is
first turned on, or the light stays on or comes
on while driving, have the airbag system checked by an
authorized dealer.26. Low Washer Fluid Indicator
This light comes on when the washer fluid level falls
below approximately 1/4 full. The light will remain on
until fluid is added and ignition switch is cycled.
27. Cruise Light
This indicator lights when the electronic speed control
system is turned on.
28. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven.
U.S. federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. There-
fore, if the odometer reading is changed during repair or
replacement, be sure to keep a record of the reading
before and after the service so that the correct mileage can
be determined.

vehicle in the 4LOCK position on dry hard surfaced
roads. This feature provides the safety, security, and
convenience of operating in all-wheel drive at all times
regardless of road conditions.
When additional traction is required, the 4LOCK and
4LO positions can be used to lock the front and rear
driveshafts together through the transfer case inter-axle
differential and force the front and rear wheels to rotate
at the same speed. This is accomplished by rotating the
4WD Control Switch to these positions. The 4LOCK and
4LO positions are intended for loose, slippery road
surfaces only. Driving in the 4LOCK and 4LO positions
on dry hard surfaced roads may cause increased tire wear
and damage to the driveline components.
The transfer case Neutral (N) position is selected by
depressing the recessed button located on the lower left
hand corner of the 4WD Control Switch.NOTE:The transfer case Neutral (N) position is to be
used for recreational towing only. See Recreational Tow-
ing section for specific procedures on shifting into and
out of Neutral (N).
Transfer Case Position Indicator Lights
Transfer case position indicator lights are located on the
instrument cluster. If there are no indicator lights on or
flashing the transfer case position is All-Wheel Drive
(AWD) and indicate the current and desired transfer case
selection (4HI,4LOCK).
The ªSVC 4WDº warning light monitors the electric shift
4WD system. If this light remains on after engine start up
or illuminates during driving, it means that the 4WD
system is not functioning properly and that service is
required.
212 STARTING AND OPERATING

These indicators are molded into the bottom of the tread
grooves and will appear as bands when the tread depth
becomes 1/16 inch (2 mm). When the indicators appear
in 2 or more adjacent grooves, the tire should be replaced.
Many states have laws requiring tire replacement at this
point.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed (see the paragraph on tread
wear indicators). Refer to the Tire and Loading Informa-
tion placard for the size designation of your tire. The
service description and load identification will be found
on the original equipment tire. Failure to use equivalent
replacement tires may adversely affect the safety, han-
dling, and ride of your vehicle. We recommend that you
contact your original equipment or an authorized tire
dealer with any questions you may have on tire specifi-
cations or capability.

ONBOARD DIAGNOSTIC SYSTEM Ð OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the ªMalfunction Indicator Light.º It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.CAUTION!
²Prolonged driving with the ªMalfunction Indica-
tor Lightº on could cause further damage to the
emission control system. It could also affect fuel
economy and driveability. The vehicle must be
serviced before any emissions tests can be per-
formed.
²If the ªMalfunction Indicator Lightº is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur.
Immediate service is required.

EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle's emissions control system.
Failure to pass could prevent vehicle registration.
For states which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Lamp)
is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system should be determined
not ready for the I/M test, your vehicle may fail the test.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 light will blink for approximately 5 sec-
onds and then remain on until the first engine crank or
