2007 DODGE GRAND CARAVAN tire pressure

Section of this manual. More frequent rotation is permis-
sible if desired. The reasons for any rapid or unusual
wear should be corrected prior to rotation being per-
formed.
The suggested rotation method is the “forward-cross”
shown in the following diagram. TIRE PRESSURE MONITOR SYSTEM (TPMS) — IF
EQUIPPED

Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Lamp will
illuminate in the instrument cluster and an audible
chime will be activated when one or more of the
four active road tire pressures are low. The audible chime
will sound once every ignition cycle for each low tire
condition that it detects.
Should this occur you should stop as soon as possible,
check the inflation pressure of each tire on your vehicle,
and inflate each tire to the pressure recommended by the
vehicle tire pressure placard. The system will automati-
cally update and the Tire Pressure Monitor System Tell-
tale Lamp will extinguish once the updated tire pres-
sure(s) have been received.
NOTE: The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) to receive this infor-
mation. NOTE: A low spare or compact tire pressure will not
cause the Tire Pressure Monitor System Telltale Lamp to
illuminate or the chime to sound.
Base Tire Pressure Monitoring System with
Electronic Vehicle Information Center (EVIC) — If
Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels (EXCLUDING THE SPARE
TIRE). Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to the Re-
ceiver Module.
NOTE: It is particularly important, for you to check the
tire pressure in all of your tires regularly and too main-
tain the proper pressure.
The Tire Pressure Monitor System (TPMS) consists of the
following components: STARTING AND OPERATING 349

Service Tire System Soon
The Tire Pressure Monitoring Telltale Lamp will flash on
and off for 60 seconds 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 Electronic Vehicle Information Center
(EVIC) will display a “SERVICE TIRE SYSTEM SOON”
text message. The flash cycle will repeat every ten
minutes, without an audible chime, until the condition no
longer exists. The flash cycle sequence will repeat and an
audible chime will sound once every ignition cycle for
each condition that it detects.
NOTE: If a temporary spare tire is in use and none of
the remaining 3 active road tire pressures are low, a
“SERVICE TIRE SYSTEM SOON textual message will
appear in the EVIC after 10 minutes of driving, CAUTION!The Tire Pressure Monitoring System (TPMS) has
been optimized for the original equipment tires and
wheels. TPMS pressures have been established for
the tire size equipped on your vehicle. Undesirable
system operation or sensor damage may result when
using replacement equipment that is not of the same
size, type, and/or style. After-market wheels can
cause sensor damage. Do not use tire sealant from a
can, or balance beads if your vehicle is equipped
with a Tire Pressure Monitor System, as damage to
the sensors may result. STARTING AND OPERATING 351

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:

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:

Tire Size
The tire size on the 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 insure 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. STARTING AND OPERATING 365

Tires–General Information section of this manual on
Tire Pressures for proper tire inflation procedures.
Also, check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to the Tires–General
Information section of this manual on Tread Wear
Indicators for the proper inspection procedure.
When replacing tires refer to the Tires–General Infor-
mation section of this manual on Replacement Tires for
proper tire replacement procedures. Replacing tires
with a higher load carrying capacity will not increase
the vehicle’s GVWR and GAWR limits. Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
An electronically actuated trailer brake controller is
required when towing a trailer with electronically
actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.
Trailer brakes are recommended for trailers over 1,000
lbs (454 kg) and required for trailers in excess of 2,000
lbs (907 kg).378 STARTING AND OPERATING

WARNING!A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, see Section 7, Maintenance, of this
manual. Follow the warnings under the Cooling
System Pressure Cap paragraph. JACKING AND TIRE CHANGING
