2007 DODGE CARAVAN fuel pressure

Airbag Light
The light should come on and remain on for 6 to 8
seconds as a bulb check when the ignition switch is first
turned ON. If the LED is not lit during starting, have it
checked. If the light stays on or comes on while driving,
have the system checked by an authorized dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects lodged in the tread. Inspect tread and sidewall for cuts or
cracks. Check wheel nuts for tightness, and tires (includ-
ing spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil or other fluid leaks. Also, if gasoline
fumes are detected or fuel, power steering fluid, trans-
mission fluid or brake fluid leaks are suspected, the cause
should be located and corrected immediately.
90 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•Step Button
Push this button to cycle through all the Compass/Mini-
trip Computer displays.
•US/M Button
Press this button to convert the display from U.S. to
metric.
To Reset The Display
Pressing the Reset button once will clear the resettable
function currently being displayed. Resettable functions
are average fuel economy, trip odometer and elapsed
time. Pressing the reset button twice within four seconds
will clear all resettable functions. Reset will only occur if
a resettable function is currently being displayed.
Electronic Vehicle Information Center (EVIC) — If
Equipped
The Electronic Vehicle Information Center, when the
appropriate conditions exist, displays the following
WARNING messages and symbols. Each message is
accompanied by a single chime:
•TURN SIGNALS ON (with graphic)
•PERFORM SERVICE
•DOOR AJAR (one or more, with graphic)
•LIFTGATE AJAR (with graphic)
•WASHER FLUID LOW (with graphic)
•1,2,3 OR 4 LOW TIRE(S) PRESSURE (Refer to ”Tire
Pressure Monitor System” in the “Starting And Oper-
ating, Tire Section”)

INSTRUMENT CLUSTER DESCRIPTIONS
1. Fuel Gauge
The pointer shows the level of fuel in the fuel tank when
the ignition switch is in the ON position.
2. Tire Pressure Monitoring Telltale Lamp — If
EquippedEach tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly underinflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly underinflated tire causes the tire to
overheat and can lead to tire failure. Underinflation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
NOTE:
The Tire Pressure Monitoring System (TPMS) is
not a substitute for proper tire maintenance, and it is the
driver ’s responsibility to maintain correct tire pressure,
even if underinflation has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.
The Tire Pressure Monitoring Telltale Lamp will illumi-
nate in the instrument cluster, and an audible chime will
be activated when one or more tire pressures is low. The
TPMS Telltale Lamp will flash on and off for 60 seconds

when a system fault is detected. The flash cycle will
repeat every ten minutes or until the fault condition is
removed and reset.
CAUTION!
The Tire Pressure Monitoring System (TPMS) has
been optimized for the original equipment tires and
wheels. TPMS pressures and warning have been
established for the tire size equipped on your ve-
hicle. Undesirable system operation or sensor dam-
age may result when using replacement equipment
that is not of the same size, type, and / or style.
Aftermarket wheels can cause sensor damage. Do
not use tire sealant from a can, or balance beads if
your vehicle is equipped with a TPMS, as damage to
the sensors may result.
3. Low Fuel LightWhen the fuel level reaches approximately 3.0
gallons (11.0 liters) this light will turn on and
remain on until fuel is added.
4. Turn Signal Indicators The arrow will flash with the exterior turn signal
when the turn signal lever is operated.
If the vehicle electronics sense that the vehicle has
traveled about one mile with the turn signals on, a chime
will sound to alert you to turn the signals off. If either
indicator flashes at a rapid rate, check for a defective
outside light bulb.
5. Liftgate Ajar This light turns on if the liftgate is not com-
pletely closed.

2. Economy—
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Under inflation, also increases
tire rolling resistance and results in higher fuel consump-
tion.
3. Ride Comfort and Vehicle Stability—
Proper tire inflation contributes to a comfortable ride.
Over inflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed either on
the face of the driver’s door or on the driver’s side “B”
pillar. Some vehicles may have Supplemental Tire Pressure
Information for vehicle loads that are less than the
maximum loaded vehicle condition. These pressure con-
ditions will be found in the “Supplemental Tire Pressure
Information” section of this manual.

CAUTION!
After inspecting or adjusting the tire pressure al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the wheel rim sensor.
NOTE:
•The Tire Pressure Monitoring System does not monitor
the temporary spare tire.
•The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
•The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
•Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underin-
flation also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stopping
ability.
•The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the Tire
Pressure Monitoring Telltale Lamp.
Using Your Compact Spare — Basic Tire
Pressure Monitoring System Only
Your vehicle is equipped with a compact spare wheel and
tire assembly that does not have a tire pressure monitor-
ing sensor. Therefore, it will not be monitored by the Tire
Pressure Monitor System (TPMS). In the event that a
compact spare tire is used to replace a low pressure road
tire, the next ignition key cycle will still show the Tire
352 STARTING AND OPERATING

Pressure Monitoring Lamp to be ON, and a Chime will
sound. This sequence will repeat for every key cycle until
the original TPMS tire has been properly repaired (or
replaced) and put back on the vehicle in place of the
compact spare tire.
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:
•This device may not cause harmful interference.
•This device must accept any interference received,
including interference that may cause undesired op-
eration.
The tire pressure sensors are covered under one of the

FUEL REQUIREMENTS
Your vehicle is designed to meet all emis-
sion regulations and provide excellent fuel
economy when using high quality regular
unleaded gasoline with an octane rating of
87. The use of premium gasoline is not
recommended. The use of premium gaso-
line will provide no benefit over high quality regular
gasolines, and in some circumstances, may result in
poorer performance.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required.
