2007 DODGE CARAVAN ECU

WARNING!
Cargo must be securely tied before driving your
vehicle. Improperly secured loads can fly off the
vehicle, particularly at high speeds, resulting in
personal injury or property damage. Follow the Roof
Rack Cautions when carrying cargo on your roof
rack.
LOAD LEVELING SYSTEM
The automatic load leveling system will provide a level
riding vehicle under most passenger and cargo loading
conditions.
A hydraulic pump contained within the shock absorbers
raises the rear of the vehicle to the correct height. It takes
approximately 1 mile (1.6 km) of driving for the leveling
to complete depending on road surface conditions. If the leveled vehicle is not moved for approximately 15
hours, the leveling system will bleed itself down. The
vehicle must be driven to reset the system.
WARNING!
Do not install the load leveling system on vehicles
that are not equipped with Anti-Lock Brakes. Ve-
hicles without Anti-Lock Brakes (ABS) have a
height-sensing proportioning valve. Installing a lev-
eling system will render this system ineffective,
inappropriately reducing rear brake pressure, result-
ing in increased stopping distances. You could have
an accident.
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 201

Reset Mode - Electronic Transmission
The transmission is monitored electronically for abnor-
mal conditions. If a condition is detected that could cause
damage, the transmission automatically shifts into sec-
ond gear. The transmission remains in second gear
despite the forward gear selected. Park (P), Reverse (R),
and Neutral (N) will continue to operate. This Reset
feature allows the vehicle to be driven to a dealer for
service without damaging the transmission.
In the event that the problem has been momentary, the
transmission can be reset to regain all forward gears.
•Stop the vehicle and shift into Park (P).
•Turn the key to OFF then restart the engine.
•Shift into the desired range and resume driving.
NOTE: Even if the transmission can be reset, it is
recommended that you visit a dealer at your earliest possible convenience. Your dealer has diagnostic equip-
ment to determine if the problem could recur.
If the transmission cannot be reset, dealer service is
required.
Gear Ranges
DO NOT race the engine
when shifting from PARK
or NEUTRAL positions into
another gear range.
“P” Park
Supplements the parking brake by locking the transmis-
sion. The engine can be started in this range. Never
attempt to use PARK while vehicle is in motion.
Apply parking brake when leaving vehicle in this range.

Loading
To load your vehicle properly, first figure out its empty
weight, axle by axle and side by side. Store heavier items
down low and be sure you distribute their weight as
evenly as possible. Stow all loose items securely before
driving. If weighing the loaded vehicle shows that you
have exceeded either GAWR, but the total load is within
the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.CAUTION!
Do not load your vehicle any heavier than the
GVWR or the maximum front and rear GAWR. If
you do, parts on your vehicle can break, or it can
change the way your vehicle handles. This could
cause you to lose control. Also overloading can
shorten the life of your vehicle.
366 STARTING AND OPERATING

Towing Requirements
To promote proper break-in of your new vehicle driv-
etrain components the following guidelines are recom-
mended:
CAUTION!
•Avoid towing a trailer for the first 500 miles (805
km) of vehicle operation. Doing so may damage
your vehicle.
•During the first 500 miles (805 km) of trailer
towing, limit your speed to 50 mph (80 km/h).
Perform the maintenance listed in Section 8 of this
manual. When towing a trailer, never exceed the GAWR,
or GCWR, ratings.
WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.

Jacking Instructions — Stow ’n Go Seating
Preparations For Jacking
WARNING!
Carefully follow these tire changing warnings to help prevent
personal injury or damage to your vehicle:
•Do not attempt to change a tire on the side of the vehicle close
to moving traffic. Pull far enough off the road to avoid the
danger of being hit when operating the jack or changing the
wheel.
•Always park on a firm, level surface before raising the vehicle.•Block the wheel diagonally opposite the wheel to be raised.•Apply the parking brake firmly before jacking.•Never start the engine with the vehicle on a jack.•Do not let anyone sit in the vehicle when it is on a jack.•Do not get under the vehicle when it is on a jack.•Only use the jack in the positions indicated.•If working on or near a roadway, be extremely careful of motor
traffic.
•To assure that spare tires, flat or inflated are securely stowed,
spares must be stowed with the value stem facing the ground.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
•Turn on the Hazard Warning Flasher.
•Block both the front and rear
of the wheel diagonally oppo-
site the jacking position. For
example, if changing the right
front tire, block the left rear
wheel.
•Passengers should not remain in the vehicle when the
vehicle is being jacked.

6. These locations are on the sill flange of the body and
consist of a pair of downstanding tabs. The jack is to be
located, engaging the flange, between the pair of tabs
closest to the wheel to be changed. Place the wrench on
the jack screw and turn to the right until the jack head is
properly engaged in the described location. Do not raise
the vehicle until you are sure the jack is securely
engaged.
CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated in step 5.
7. Raise the vehicle by turning the jack screw to the right,
using the swivel wrench. Raise the vehicle only until the
tire just clears the surface and enough clearance is
obtained to install the spare tire. Minimum tire lift
provides maximum stability.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable. It could slip off the jack and
hurt someone near it. Raise the vehicle only enough
to remove the tire.
8. Remove the wheel lug nuts, for vehicles with wheel
covers, remove the cover from the wheel by hand. Do not
pry the wheel cover off. Then pull the wheel off the hub.
9. Install the compact spare tire. Lightly tighten the lug
nuts. To avoid the risk of forcing the vehicle off the jack,
do not tighten the lug nuts fully until the vehicle has been
lowered.
NOTE: Do not install the wheel cover on the compact
spare.
Do not use a hammer or force to install the wheel covers.
394 WHAT TO DO IN EMERGENCIES

15. Stow the jack, jack handle and winch handle tools.
16. Check the compact spare tire pressure as soon as
possible. Correct pressure as required.Secure The Spare Tire As Follows:
1. To stow the compact spare tire/cover assembly on
vehicles equipped with Stow ’n Go seating, assemble the
winch handle extensions to form a “T’ and fit the winch
“T” handle over the drive nut. Rotate the nut to the left
until the winch mechanism stops turning freely, this will
allow enough slack in the cable to allow you to pull the
wheel spacer out from under the vehicle.
