2011 DODGE CARAVAN tire pressure

The “Tire Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds, and remain on solid when a
system fault is detected. The system fault will also sound
a chime. If the ignition switch is cycled, this sequence will
repeat, providing the system fault still exists. The “Tire
Pressure Monitoring Telltale Light” will turn off when
the fault condition no longer exists. A system fault can
occur with any of the following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the TPMS
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Accumulation of excessive snow and/or ice around
the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.Vehicles With Compact Spare
1. The compact spare tire (if equipped) does not have a
TPMS sensor. Therefore the TPMS will not monitor the
pressure in the compact spare tire.
2. If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, a chime will
sound, a
TIRE LOW PRESSURE message will be dis-
played and the “Tire Pressure Monitoring Telltale Light”
will turn on.
3. After driving for up to 20 minutes above 15 mph
(24 km/h), the “Tire Pressure Monitoring Telltale Light”
will flash on and off for 75 seconds and then remain on
solid.
4. For each subsequent ignition switch cycle, a chime will
sound, the “Tire Pressure Monitoring Telltale Light” will
flash on and off for 75 seconds and then remain on solid.

5. Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare
tire, the TPMS will automatically update, and the “Tire
Pressure Monitoring Telltale Light” will turn off as long
as no tire pressure is below the low-pressure warning
limit in any of the four active road tires. The vehicle may
need to be driven for up to 20 minutes above 15 mph
(24 km/h) for the TPMS to receive this information.
Premium System – If Equipped
The TPMS uses wireless technology with wheel rim-
mounted electronic sensors to monitor tire pressure lev-
els. Sensors mounted to each wheel as part of the valve
stem transmit tire pressure readings to the Receiver
Module.
NOTE:It is particularly important to regularly check
and maintain proper tire pressure in all the tires. The Premium TPMS consists of the following compo-
nents:
•Receiver Module
•Four TPMS Sensors
•Various TPMS messages, which display in the Elec-
tronic Vehicle Information Center (EVIC), and graph-
ics displaying tire pressures
•TPMS Telltale Warning Light5

TPMS Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will illumi-
nate in the instrument cluster, and an audible chime will
be activated when one or more of the four active road tire
pressures are low. In addition, the EVIC will display a
“LOW TIRE PRESSURE” message for a minimum of five
seconds and a graphic display of the pressure value(s)
with the low tire(s) flashing.

Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as possible,
and inflate the low tire(s) that is flashing on the graphic
display to the vehicle’s recommended cold tire pressure
value. The system will automatically update, the graphic
display of the pressure value(s) will stop flashing, and
the “Tire Pressure Monitoring Telltale Light” will extin-
guish once the updated tire pressure(s) have been re-
ceived. The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) to receive this
information.
SERVICE TPM SYSTEM Message
The “Tire Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds, and remain on solid when a
system fault is detected. The system fault will also sound
a chime. The EVIC will display a “SERVICE TPM SYS-
TEM” message for a minimum of five seconds. This textmessage is then followed by a graphic display, with
--in
place of the pressure value(s) indicating which TPMS
Sensor(s) is not being received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the “Tire Pressure Monitoring Telltale

Light” will no longer flash, the “SERVICE TPM SYSTEM”
message will not be present, and a pressure value will be
displayed instead of dashes. A system fault can occur by
any of the following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the TPMS
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Accumulation of excessive snow and/or ice around
the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
The EVIC will also display a “SERVICE TPM SYSTEM”
message for a minimum of five seconds when a system
fault possibly related to an incorrect sensor location faultis present. In this case, the “SERVICE TPM SYSTEM”
message is then followed by a graphic display with
pressure values still shown. This indicates that the pres-
sure values are still being received from the TPM sensors
but they may not be in the correct vehicle position. The
system still needs to be serviced as long as the “SERVICE
TPM SYSTEM” message exists.
Vehicles With Compact Spare
1. The compact spare tire (if equipped) does not have a
TPMS. Therefore, the TPMS will not monitor the pressure
in the compact spare tire.
2. If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, the “Tire
Pressure Monitoring Telltale Light” will remain on, the
TIRE LOW PRESSURE
message will be displayed, a
chime will sound, and the EVIC will still display a
flashing pressure value in the graphic display.

3. After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the “Tire Pressure Monitoring Telltale
Light” will flash on and off for 75 seconds and then
remain on solid. In addition, the EVIC will display a
“SERVICE TPM SYSTEM” message for a minimum of
five seconds and then display dashes (- -) in place of the
pressure value.
4. For each subsequent ignition switch cycle, a chime will
sound, the “Tire Pressure Monitoring Telltale Light” will
flash on and off for 75 seconds and then remain on solid,
and the EVIC will display a “SERVICE TPM SYSTEM”
message for a minimum of five seconds and then display
dashes (- -) in place of the pressure value.
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
“Tire Pressure Monitoring Telltale Light” will turn off
and the graphic in the EVIC will display a new pressurevalue 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
20 minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.

FUEL REQUIREMENTS
3.6L Engine
This engine is designed to meet all emis-
sions regulations and provide excellent
fuel economy and performance when us-
ing high-quality unleaded “regular” gaso-
line having an octane rating of 87. The use
of premium gasoline is not recommended,
as it will not provide any benefit over regular gasoline in
these engines.
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. Poor quality gasoline can cause problems such
as hard starting, stalling, and hesitations. If you experi-
ence these symptoms, try another brand of gasoline
before considering service for the vehicle.
Over 40 auto manufacturers worldwide have issued and
endorsed consistent gasoline specifications (the World-
wide Fuel Charter, WWFC) which define fuel properties
necessary to deliver enhanced emissions, performance,
and durability for your vehicle. The manufacturer recom-
mends the use of gasolines that meet the WWFC speci-
fications if they are available.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline.”
Reformulated gasoline contains oxygenates and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.

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.
