2011 DODGE GRAND CARAVAN gas type

It also includes diagnostics that will illuminate the instru-
ment cluster Air Bag Warning Light if a malfunction is
noted that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction.
WARNING!
Ignoring the Air Bag Warning Light in your instru-
ment panel could mean you won’t have the air bags
to protect you in a collision. If the light does not come
on as a bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if it comes
on as you drive, have an authorized dealer service the
air bag system immediately.
Driver And Passenger Advanced Front Air Bag
Inflator Units
The Driver and Passenger Advanced Front Air Bag
Inflator Units are located in the center of the steering
wheel and on the right side of the instrument panel.When the ORC detects a collision requiring the Ad-
vanced Front Air Bags, it signals the inflator units. A large
quantity of non-toxic gas is generated to inflate the
Advanced Front Air Bags. Different air bag inflation rates
are possible, based on the collision type and severity. The
steering wheel hub trim cover and the upper right side of
the instrument panel separate and fold out of the way as
the air bags inflate to their full size. The air bags fully
inflate in about 50 to 70 milliseconds. This is about half of
the time it takes to blink your eyes. The air bags then
quickly deflate while helping to restrain the driver and
front passenger.
The Advanced Front Air Bag gas is vented through the
vent holes in the sides of the air bag. In this way, the air
bags do not interfere with your control of the vehicle.
80 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Supplemental Driver Side Knee Air Bag Inflator
Unit
The Supplemental Driver Side Knee Air Bag unit is located
in the instrument panel trim beneath the steering column.
When the ORC detects a collision requiring the air bag, it
signals the inflator units. A large quantity of non-toxic gas is
generated to inflate the Supplemental Driver Side Knee Air
Bag. The trim cover separates and folds out of the way
allowing the air bag to inflate to the full size. The air bag
fully inflates in about 15 to 20 milliseconds. The Supple-
mental Driver Side Knee Air Bag gas is vented through
small vent holes in the side of the air bag.
Supplemental Seat-Mounted Side Air Bag (SAB)
Inflator Units
The Supplemental Seat-Mounted Side Air Bags (SAB) are
designed to activate only in certain side collisions.
The ORC determines if a side collision requires the side air
bags to inflate, based on the severity and type of collision.
Based on the severity and type of collision, the side air
bag inflator on the crash side of the vehicle may be
triggered, releasing a quantity of non-toxic gas. The
inflating SAB exits through the seat seam into the space
between the occupant and the door. The SAB fully inflate
in about 10 milliseconds. The side air bag moves at a very
high speed and with such a high force that it could injure
you if you are not seated properly, or if items are
positioned in the area where the side air bag inflates. This
especially applies to children.
Supplemental Side Air Bag Inflatable Curtain
(SABIC) Inflator Units
During collisions where the impact is confined to a
particular area of the side of the vehicle, the ORC may
deploy the SABIC air bags, depending on the severity
and type of collision. In these events, the ORC will
deploy the SABIC only on the impact side of the vehicle.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 81

Ethanol Fuel (E-85)
E-85 is a mixture of approximately 85% fuel ethanol and
15% unleaded gasoline.
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 between E-85 and unleaded gasoline should be
avoided.When you do switch fuel types it is recommended that:
•you do not switch when the fuel gauge indicates less
than 1/4 full
•you do not add less than 5 gallons (19 Liters) when
refueling
•you operate the vehicle immediately after refueling for
a period of at least 5 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 90° F (32° C),
you may experience hard starting and rough idle
following start up even if the above recommendations
are followed.
414 STARTING AND OPERATING

If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
•Do not overfill the coolant recovery bottle.
•Check the engine coolant (antifreeze) freeze point in
the radiator and in the coolant recovery bottle. If
engine coolant (antifreeze) needs to be added, contents
of the coolant recovery bottle must also be protected
against freezing.
•If frequent engine coolant (antifreeze) additions are
required, or if the level in the coolant recovery bottle
does not drop when the engine cools, the cooling
system should be pressure tested for leaks.
•Maintain engine coolant (antifreeze) concentration at
50% HOAT engine coolant (antifreeze) (minimum)
and distilled water for proper corrosion protection of
your engine, which contains aluminum components.
•Make sure that the radiator and coolant recovery
bottle overflow hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, also keep the front of
the condenser clean.
•Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory coolant performance, poor gas
mileage, and increased emissions.
Brakes
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.7
