2008 DODGE CARAVAN Owners Manual

CAUTION!
Damage to the fuel system or emission control sys-
tem could result from using an improper fuel tank
filler tube cap (gas cap). A poorly fitting cap could let
impurities into the fuel system and may cause the
Malfunction Indicator Light (MIL) to turn on due to
fuel vapors escaping from the system.
CAUTION!
To avoid fuel spillage and overfilling, do not ªtop
offº the fuel tank after filling.
NOTE:When the fuel nozzle ªclicksº or shuts off, the
fuel tank is full.
WARNING!
²Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
²Never add fuel when the engine is running. This is
in violation of most state and federal fire regula-
tions and will cause the malfunction indicator
light to turn on.
NOTE:
²Tighten the fuel filler cap until you hear a ªclickingº
sound. This is an indication that the fuel filler cap is
properly tightened.
²If the gas cap is not tightened properly, the Malfunc-
tion Indicator Light may come on. Be sure the gas cap
is tightened every time the vehicle is refueled.

WARNING!
A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling.
Loose Fuel Filler Cap Message
²
If thegASCAPmessage is displayed in the instrument
cluster, this signifies a leak or change in the evapora-
tive system is detected. Sometimes this is the result of
a loosely fitting (or possibly damaged) filler cap.
Tighten the fuel filler cap properly and press the
odometer reset button to turn thegASCAPmessage
off.
²Make sure that the fuel filler cap is tightened each time
the vehicle is refueled.
²If the problem continues, the message will appear the
next time the vehicle is started. See your authorized
dealer service center as soon as possible. See Section 7
of this manual for more information.
FLEXIBLE FUEL Ð 3.3L ENGINES ONLY
E-85 General Information
The information in this section is for Flexible Fuel Ve-
hicles (FFV) only. These vehicles can be identified by the
unique fuel filler door label that states:Ethanol (E-85) or
Unleaded Gasoline Only.This section only covers those
subjects that are unique to these vehicles. Please refer to
the other sections of this manual for information on
features that are common between Flexible Fuel and
gasoline only powered vehicles.
384 STARTING AND OPERATING

CAUTION!
Only vehicles with the E-85 Decal and/or fuel filler
door label can operate on E-85.
ETHANOL FUEL (E-85)
E-85 is a mixture of approximately 85% fuel ethanol and
15% unleaded gasoline.

STARTING AND OPERATING 385

WARNING!
Ethanol vapors are extremely flammable and could
cause serious personal injury. Never have any smok-
ing materials lit in or near the vehicle when remov-
ing the fuel filler tube cap (gas cap) or filling the
tank. Do not use E-85 as a cleaning agent and never
use it near an open flame.
Fuel Requirements
Your vehicle will operate on both unleaded gasoline with
an octane rating of 87, or E-85 fuel, or any mixture of
these two.For best results, a refueling pattern that alternates be-
tween E-85 and unleaded gasoline should be avoided.
When you do switch fuels, it is recommended that:
²you do not switch when the fuel gauge indicates less
than one-quarter full
²you do not add less than 5 gal (19 L) when refueling
²you operate the vehicle immediately after refueling for
a period of at least five minutes
Observing these precautions will avoid possible hard
starting and/or significant deterioration in driveability
during warm up.
NOTE:When the ambient temperature is above 90ÉF
(32ÉC), you may experience hard starting and rough idle
following start-up even if the above recommendations
are followed.
386 STARTING AND OPERATING

Selection Of Engine Oil For Flexible Fuel Vehicles
(FFV) E-85 and Gasoline Vehicles
FFV vehicles operated on E85 require specially formulated
engine oils. These special requirements are included in
Mopartengine oils, and in equivalent oils meeting
DaimlerChrysler Specification MS-6395. The manufacturer
only recommends engine oils that are API Certified and
meet the requirements of Material Standard MS-6395. MS-
6395 contains additional requirements, developed during
extensive fleet testing, to provide additional protection to
DaimlerChrysler Corporation engines. Use Mopartor an
equivalent oil meeting the specification MS-6395.
Starting
The characteristics of E-85 fuel make it unsuitable for use
when ambient temperatures fall below 0ÉF (-18ÉC). In the
range of 0ÉF (-18ÉC) to 32ÉF (0ÉC), you may experience an
increase in the time it takes for your engine to start, and
a deterioration in driveability (sags and/or hesitations)
until the engine is fully warmed up.
Cruising Range
Because E-85 fuel contains less energy per gallon than
gasoline, you will experience an increase in fuel con-
sumption. You can expect your MPG and your driving
range to decrease by about 30% compared to gasoline
operation.
Replacement Parts
Many components in your Flexible Fuel Vehicle (FFV) are
designed to be compatible with ethanol. Always be sure
that your vehicle is serviced with correct ethanol com-
patible parts.
CAUTION!
Replacing fuel system components with non-ethanol
compatible components can damage your vehicle.
STARTING AND OPERATING 387

Maintenance
If you operate the vehicle using E-85 fuel, follow the
maintenance schedule section of this manual.
CAUTION!
Do not use ethanol mixture greater than 85% in your
vehicle. It will cause difficulty in cold starting and
may affect driveability.
VEHICLE LOADING
As required by National Highway Traffic Safety Admin-
istration Regulations, your vehicle has a certification
label affixed to the driver's side door or pillar.If seats are removed for carrying cargo, do not exceed the
specified GVWR and GAWR.Vehicle Certification Label Location
388 STARTING AND OPERATING

Vehicle Certification Label
Your vehicle has a Vehicle Certification Label attached to
the driver's door pillar.
The label contains the following information:
²Name of manufacturer
²Month and year of manufacture
²Gross Vehicle Weight Rating (GVWR)
²Gross Axle Weight Rating (GAWR) front
²Gross Axle Weight Rating (GAWR) rear
²Vehicle Identification Number (VIN)
²Type of Vehicle
²Month Day and Hour of Manufacture (MDH)
The bar code allows a computer scanner to read the
Vehicle Identification Number (VIN).
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, and cargo. The total
load must be limited so that you do not exceed the
GVWR.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR.
WARNING!
Because the front wheels drive and steer the vehicle,
it is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition
can result if either rating is exceeded. You could lose
control of the vehicle and have an accident.
STARTING AND OPERATING 389

Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
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.
Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and front
and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to ensure that
it is not over the GVWR.
Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle's
GVWR.
