DODGE GRAND CARAVAN 2008 5.G Owners Manual

The manufacturer supports the use of reformulated gaso-
lines. Properly blended reformulated gasolines will pro-
vide excellent performance and durability of engine and
fuel system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as 10% ethanol, MTBE, and ETBE. Oxygen-
ates are required in some areas of the country during the
winter months to reduce carbon monoxide emissions.
Fuels blended with these oxygenates may be used in
your vehicle.
CAUTION!
DO NOT use gasolines containing Methanol or E85
Ethanol. Use of these blends may result in starting
and driveability problems and may damage critical
fuel system components.Problems that result from using methanol/gasoline or
E85 Ethanol blends are not the responsibility of the
manufacturer. While MTBE is an oxygenate made from
Methanol, it does not have the negative effects of Metha-
nol.
MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emission system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT.

It is even more important to look for gasolines without
MMT in Canada, because MMT can be used at levels
higher than those allowed in the United States.
MMT is prohibited in Federal and California reformu-
lated gasolines.
Materials Added to Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives are not needed under
normal conditions and would result in additional cost.
Therefore you should not have to add anything to the
fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle's
performance:
²The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance
and damage the emission control system.
²An out-of-tune engine, or certain fuel or ignition
malfunctions, 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 authorized dealer for service assistance.
380 STARTING AND OPERATING

²The use of fuel additives which are now being sold as
octane enhancers is not recommended. Most 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.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
²To prevent carbon monoxide poisoning DO NOT
inhale exhaust gases. They contain carbon monox-
ide, a colorless and odorless gas which can kill.
²NEVER run the engine in a closed area, such as a
garage, and NEVER sit in a parked vehicle with
the engine running for an extended period. If the
vehicle is stopped in an open area with the engine
running for more than a short period, adjust the
ventilation system to force fresh, outside air into
the vehicle.

WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
²Guard against carbon monoxide with proper
maintenance. Have the exhaust system inspected
every time the vehicle is raised. Have any abnor-
mal conditions repaired promptly. Until repaired,
drive with all side windows fully open.
²Keep the liftgate closed when driving your vehicle
to prevent carbon monoxide and other poisonous
exhaust gases from entering the vehicle.
ADDING FUEL
Fuel Filler Cap (Gas Cap)
As a reminder, a fuel icon with an arrow
indicating which side of the vehicle the fuel
filler door is located on, is located in the
instrument cluster, just below the Fuel Gage.
The gas cap is located behind the fuel filler door on the
left side of the vehicle. If the gas cap is lost or damaged,
be sure the replacement cap is for use with this vehicle.
NOTE:The driver's side sliding door cannot be opened
while the fuel door is open. This feature operates only
when the sliding door is fully closed prior to opening the
fuel door.
382 STARTING AND OPERATING

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)

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.

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
