2009 DODGE GRAND CARAVAN trailer

When the vehicle is started, the BSM warning light will
be momentarily illuminated in both outside rear view
mirrors to let the driver know that the system is opera-
tional. The BSM system sensors operate when the vehicle
is in any forward gear or REVERSE and enters stand by
mode when the vehicle is in PARK.
The BSM detection zone covers approximately one lane
on both sides of the vehicle (11 ft or 3.35 m). The zone
starts at the outside rear view mirror and extends ap-
proximately 20 ft (6 m) to the rear of the vehicle. The BSM
system monitors the detection zones on both sides of the
vehicle when the vehicle speed has reached approxi-
mately 6 mph (10 km/h) or higher and will alert the
driver of vehicles in these areas.NOTE:
The BSM system does NOT alert the driver about
rapidly approaching vehicles that are outside the
detection zones.
The BSM system detection zone DOES NOT change if
your vehicle is towing a trailer. Therefore, visually
verify the adjacent lane is clear for both your vehicle
and trailer before making a lane change. If the trailer
or other object (i.e., bicycle, sports equipment) extends
beyond the side of your vehicle, this may result in the
BSM warning light remaining illuminated the entire
time the vehicle is in a forward gear.

CAUTION!
To avoid vehicle damage, the Rear Park Assist
should only be used as a parking aid and is unable
to recognize every obstacle, including small ob-
jects. Parking curbs might be temporarily detected
or not detected at all. Obstacles located above or
below the sensors will not be detected when they
are in close proximity to the rear of the vehicle.
To avoid vehicle damage, the vehicle must be
driven slowly when using the Rear Park Assist, to
be able to stop in time when an obstacle is
detected. It is recommended that you look over
your shoulder when using the Rear Park Assist.
NOTE:
Ensure that the rear bumper is free of dirt and debris
to keep the system operating properly.
Jackhammers, large trucks, and other vibrations could
affect the performance of the system.
Enabling and Disabling The Rear Park Assist
There are times when you may want to disable the Rear
Park Assist, such as when towing a trailer.
Vehicles Equipped With the Electronic Vehicle
Information Center (EVIC)
You can turn the Rear Park Assist ON or OFF through the
EVIC. For details, refer to “Personal Settings (Customer-
Programmable Features)” under “Electronic Vehicle In-
formation Center (EVIC)” in Section 4.
Vehicles Equipped With the Compass Mini-Trip
Computer (CMTC)
You can turn the Rear Park Assist ON or OFF through the
CMTC by pressing the left reset button in the instrument
cluster. Turn the ignition switch to the ON position, then
press and hold the RESET button for approximately two
seconds.

INSTRUMENT CLUSTER DESCRIPTIONS1. Fuel Gauge
The pointer shows the level of fuel in the fuel tank when
the ignition switch is in the ON position.
2. Fuel Door Reminder
The arrow in this symbol is a reminder that the
Fuel Filler Door is located on the left side of the
vehicle.
3. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily. The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range. CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If temperature gauge reads
“H“, pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H”, and you hear continuous chimes,
turn the engine off immediately, and call an autho-
rized dealer for service.240 UNDERSTANDING YOUR INSTRUMENT PANEL

DRIVE — Six-Speed TransaxleThis range should be used for most city and highway
driving. It provides the smoothest upshifts, downshifts,
and best fuel economy. However, use the Electronic
Range Select (ERS) mode by moving the lever — / + and
select the “5” range when frequent transaxle shifting
occurs while using the DRIVE range, such as when
operating the vehicle under heavy loading conditions,
(i.e., in hilly terrain, traveling into strong head winds or
while towing heavy trailers). Under these conditions,
using the “5” range will improve performance and
extend transaxle life by reducing excessive shifting and
heat buildup.
DRIVE — Four-Speed Transaxle
This range should be used for most city and highway
driving. It provides the smoothest upshifts, downshifts,
and best fuel economy. However, select the “3” range
when frequent transaxle shifting occurs while using the
DRIVE range, such as when operating the vehicle under
heavy loading conditions, (i.e., in hilly terrain, traveling
into strong head winds or while towing heavy trailers).
Under these conditions, using the “3” range will improve
performance and extend transaxle life by reducing exces-
sive shifting and heat buildup. CAUTION!
If the transaxle operating temperature exceeds ac-
ceptable limits, the vehicle computer will override
DRIVE and select “5” range (on six-speed transaxles)
or “3” range (on four-speed transaxles) by changing
shift points. This is done to prevent transaxle damage
due to overheating.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows
you to move the shift lever to the left (-) or right (+) when
the shift lever is in the DRIVE position, this allows the
selection of the desired top gear. For example, if you shift

LoadingThe vehicle maximum load on the tire must not exceed
the load carrying capacity of the tire on your vehicle. You
will not exceed the tire’s load carrying capacity if you
adhere to the loading conditions, tire size, and cold tire
inflation pressures specified on the Tire and Loading
Information placard and in the “Vehicle Loading” section
of this manual.
NOTE:
Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWRs) for the front and rear
axles must not be exceeded. For further information on
GAWRs, vehicle loading, and trailer towing, refer to
“Vehicle Loading” in this section.
To determine the maximum loading conditions of your
vehicle, locate the statement “The combined weight of
occupants and cargo should never exceed XXX lbs or
XXX kg” on the Tire and Loading Information placard. The combined weight of occupants, cargo/luggage and
trailer tongue weight (if applicable) should never exceed
the weight referenced here.
Steps for Determining Correct Load Limit
1. Locate the statement “The combined weight of occu-
pants and cargo should never exceed XXX lbs or XXX kg”
on your vehicle’s placard.
2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and pas-
sengers from XXX lbs or XXX kg.
4. The resulting figure equals the available amount of
cargo and luggage load capacity. For example, if “XXX”
amount equals 1,400 lbs (635 kg) and there will be five
150 lb (68 kg) passengers in your vehicle, the amount of
STARTING AND OPERATING 357 5

available cargo and luggage load capacity is 650 lbs
(295 kg) (since 5 x 150 = 750, and 1400 – 750 = 650 lbs
[295 kg]).
5. Determine the combined weight of luggage and cargo
being loaded on the vehicle. That weight may not safely
exceed the available cargo and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your
trailer will be transferred to your vehicle. Consult this
manual to determine how this reduces the available
cargo and luggage load capacity of your vehicle.NOTE:
The following table shows examples on how to calcu-
late total load, cargo/luggage, and towing capacities
of your vehicle with varying seating configurations
and number and size of occupants. This table is for
illustration purposes only and may not be accurate for
the seating and load carry capacity of your vehicle.
For the following example, the combined weight of
occupants and cargo should never exceed 865 lbs
(392 kg).

TRAILER TOWINGIn this section you will find safety tips and information
on limits to the type of towing you can reasonably do
with your vehicle. Before towing a trailer, carefully
review this information to tow your load as efficiently
and safely as possible.
To maintain warranty coverage, follow the requirements
and recommendations in this manual concerning ve-
hicles used for trailer towing.
Common Towing Definitions
The following trailer towing-related definitions will as-
sist you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo/luggage and
trailer tongue weight. The total load must be limited so
that you do not exceed the GVWR.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or tem-
porary) loaded in or on the trailer in its
9loaded and
ready for operation9 condition. The recommended way to
measure GTW is to put your fully loaded trailer on a
vehicle scale. The entire weight of the trailer must be
supported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of your vehicle
and trailer when weighed in combination.
NOTE: The GCWR rating includes a 150 lbs (68 kg)
allowance for the presence of a driver.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR.
