2008 DODGE GRAND CARAVAN fuel pressure

5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically. In addition, the
TPMS Telltale Warning Light will turn off and the
graphic in the EVIC will display a new pressure value
instead of dashes (- -), as long no tire pressure is below
the low pressure warning limit in any of the four active
road tires.
NOTE:The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) in order for the TPMS
to receive this information.
General Information
This device complies with Part 15 of the FCC rules and
RSS 210 of Industry Canada. Operation is subject to the
following conditions:
²This device may not cause harmful interference.
²This device must accept any interference received,
including interference that may cause undesired op-
eration.
The tire pressure sensors are regulated under one of the
following licenses:

FUEL REQUIREMENTS
3.3L & 3.8L Gasoline Engine
All engines are designed to meet all emis-
sions regulations and provide excellent
fuel economy and performance when us-
ing high-quality unleaded ªregularº gaso-
line having an octane rating of 87. The use
of premium gasoline is not recommended.
Under normal conditions, the use of premium gasoline
will not provide a benefit over high-quality regular
STARTING AND OPERATING 377

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.
390 STARTING AND OPERATING

²Do 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.
HOSES AND VACUUM/VAPOR HARNESSES
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling indicate deterioration of the rubber.
Pay particular attention to those hoses nearest to high
heat sources such as the exhaust manifold. Inspect hose
routing to be sure hoses do not come in contact with any
heat source or moving component which may cause heat
damage or mechanical wear.
Ensure nylon tubing in these areas has not melted or
collapsed.Inspect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
present.
Components should be replaced immediately if there is
any evidence of wear or damage that could cause failure.FUEL SYSTEM CONNECTIONS
The Electronic Fuel Injection high-pressure fuel system's
hoses and quick connect fittings have unique material
characteristics that provide adequate sealing and resist
attack by deteriorated gasoline.
You are urged to use only the manufacture specified
hoses with quick connect fittings, or their equivalent in
material and specification, in any fuel system servicing. It
is mandatory to replace any damaged hoses or quick
connect fittings that have been removed during service.
Care should be taken in installing quick connect fittings
to ensure they are properly installed and fully connected.
See your authorized dealer for service.
MAINTAINING YOUR VEHICLE 461

NOTE:
²The oil change indicator message will not monitor the
time since the last oil change. Change your vehicle's
oil if it has been six months since your last oil change
even if the oil change indicator message is NOT
illuminated.
²Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
²Under no circumstances should oil change intervals
exceed 6,000 mi (10 000 km) or six months, whichever
comes first.
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If this
scheduled oil change is performed by someone other
than your dealer, the message can be reset by referring to
the steps described under ªOil Change Requiredº in ªUse
Factory Settingsº of the EVIC section in this manual orunder ªOdometer/Trip Odometerº in the ªInstrument
Cluster Descriptions section of this manual.
At Each Stop For Fuel
²Check the engine oil level about five minutes after a
fully warmed engine is shut off. Checking the oil level
while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when
the level is at or below the ADD, SAFE or MIN mark.
²Check the windshield washer solvent and add if
required.
Once A Month
²Check tire pressure and look for unusual wear or
damage.
²Inspect the battery and clean and tighten the terminals
as required.
