2006 DODGE DURANGO fuel cap

Average Fuel Economy (AVG ECO)
Shows the average fuel economy since the last reset. This
display mode becomes less sensitive to instantaneous
changes in fuel consumption as the number of total
vehicle miles since the last reset increases. It is suggested
that this mode be reset periodically for general operation
or when driving conditions change significantly (for
example, at the end of a trip or when a trailer is
connected or disconnected).
Distance To Empty (DTE)
Shows the estimated distance that can be travelled with
the fuel remaining in the tank. The estimated distance is
determined by a weighted average of the instantaneous
and average fuel economy, according to the current fuel
tank level.
When Distance To Empty = 0, the fuel gauge pointer will
initially be on the red “E” marker. At this point (fuel
gauge pointer on the the red “E” marker) there is reservefuel capacity, which corresponds to approximately 5% of
tank volume. This reserve capacity was put in place to
prevent the likelihood of customers running out of fuel
when operating at maximum load conditions in areas
where there aren’t many gas stations.
NOTE:The Distance To Empty will remain equal to
zero, until the vehicle runs out of fuel or is refueled.
Trip Odometer (ODO)
This display shows the distance traveled since the last
reset.
Elapsed Time (ET)
This display shows the accumulated ignition ON time
since the last reset.

range (PRND21). If the PRNDL displays only the char-
acters PRND21 (no boxes) have the system checked by an
authorized dealer.
17. Trip Odometer
The trip odometer shows individual trip mileage. To
toggle between the odometer and the trip odometer,
press the Odometer/Trip Odometer Button. To reset the
Trip Odometer, press and hold the button while in trip
mode, until the Trip Odometer resets.
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged,
GASCAP will be displayed in the instrument cluster.
Tighten the fuel filler cap properly and press the odom-
eter reset button to turn the GASCAP message off. If the
problem continues, the message will appear the next time
the vehicle is started.18. 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.
19. Electronic Stability Program (ESP) Indicator Light
— If Equipped
The yellow ESP indicator light in the speedom-
eter area illuminates with the key in the igni-
tion switch turned to the ON/RUN position. It
should go out with the engine running. The
ESP/TCS Indicator Lightstarts to flash as soon as the
tires lose traction and the ESP system becomes active. The

NOTE:Tighten the gas cap until you hear a “clicking”
sound. This is an indication that the gas cap is properly
tightened. Make sure that the gas cap is tightened each
time the vehicle is refueled.
WARNING!
A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle or on a
truck bed. You could be burned. Always place gas
containers on the ground while filling.
Fuel Filler Cap (Gas Cap)
The gas cap is behind the fuel filler door. If the gas cap is
lost or damaged, be sure the replacement cap is for use
with this vehicle.NOTE:To avoid contact between fuel cap and paint,
hang tether strap over hook provided on inner fuel door.
NOTE:After fuel is added, the vehicle diagnostic sys-
tem can determine if the fuel filler cap is loose, improp-
erly installed, or damaged. A loose fuel filler cap message
will be displayed in the instrument cluster. Tighten the
gas cap until aclickingsound is heard. This is an
indication that the gas cap is properly tightened. Press
the odometer reset button to turn the message off. If the
problem persists, the message will appear the next time
the vehicle is started. This might indicate a damaged cap.
If the problem is detected twice in a row, the system will
turn on the Malfunction Indicator Light (MIL). Resolving
the problem will turn the MIL light off.
288 STARTING AND OPERATING

CAUTION!
Damage to the fuel system or emission control
system could result from using an improper fuel
tank filler tube cap (gas cap). A poorly fitting cap
could let impurities into the fuel system.
WARNING!
•Never allow any lit smoking materials near the
vehicles while removing the cap or filling the
tank.
•Never add fuel to the vehicle when the engine is
running.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s performance:
•The use of leaded gas is prohibited by Federal law. Using
leaded gasoline can impair engine performance, damage the
emission control system.
•An out-of-tune engine, or certain fuel or ignition malfunc-
tions, can cause the catalytic converter to overheat. If you
notice a pungent burning odor or some light smoke, your
engine may be out of tune or malfunctioning and may
require immediate service. Contact your dealer for service
assistance.
•When pulling a heavy load or driving a fully loaded vehicle
when the humidity is low and the temperature is high, use a
premium unleaded fuel to help prevent spark knock. If spark
knock persists, lighten the load, or engine piston damage
may result.
•The use of fuel additives which are now being sold as octane
enhancers is not recommended. Many of these products contain
high concentrations of methanol. Fuel system damage or vehicle
performance problems resulting from the use of such fuels or
additives is not the responsibility of the manufacturer.

Inflation Pressure (Cold)
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Loading
The actual total weight and the weight of the front and
rear of your vehicle at the ground can best be determined
by weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commer-
cial scale to insure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle shouldthen be determined separately to be sure that the load is
properly distributed over front and rear axle. Weighing
the vehicle may show that the GAWR of either the front
or rear axles has been exceeded but the total load is
within the specified GVWR. If so, weight must be shifted
from front to rear or rear to front as appropriate until the
specified weight limitations are met.
Store heavier items down low and be sure that the weight
is distributed equally. Stow all loose items securely before
driving.
Improper weight distribution can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
294 STARTING AND OPERATING

WARNING!
•Never allow any lit smoking materials near the
vehicles while removing the cap or filling the
tank.
•Never add fuel to the vehicle when the engine is
running.
•A fire may result if gasoline is pumped into a
portable container that is in a vehicle or on a truck
bed. You could be burned. Always place gas
containers on the ground while filling.
CHANGING A FLAT TIRE
Jack Location
In the Durango, the scissor jack and tire changing tools
are stowed under the second row seat.
The jack is secured in place with a winged stud and a
fixed stud. It is very important to secure the jack tightly
in place by engaging the slot in the base to the fixed stud
under the middle seat. The winged stud inserts through
the eyelet in the end of the jack’s worm screw.

ONBOARD DIAGNOSTIC SYSTEM — 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 “Malfunction Indicator Light.” 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!
•Prolonged driving with the “Malfunction Indica-
tor Light” 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.
•If the “Malfunction Indicator Light” is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur.
Immediate service is required.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is loose, improperly
installed, or damaged. A loose fuel filler cap message will
be displayed in the instrument cluster. Tighten the gas
