2006 DODGE CARAVAN suspension

WARNING!
•Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of
unapproved tires and wheels may change suspension
dimensions and performance characteristics, result-
ing in changes to steering, handling, and braking of
your vehicle. This can cause unpredictable handling
and stress to steering and suspension components.
You could lose control and have an accident resulting
in serious injury or death. Use only the tire and wheel
sizes with load ratings approved for your vehicle.
•Never use a tire with a smaller load index or capacity,
other than what was originally equipped on your
vehicle. Using a tire with a smaller load index could
result in tire overloading and failure. You could lose
control and have an accident.
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
Alignment And Balance
Poor suspension alignment may result in:
•Fast tire wear.
•Uneven tire wear, such as feathering and one-sided
wear.
•Vehicle pull to right or left.
Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.
336 STARTING AND OPERATING

CAUTION!
To avoid damage to your vehicle or tires, observe the following
precautions:
•Because of restricted chain clearance between tires and
other suspension components, it is important that only
chains in good condition are used. Broken chains can cause
serious damage. Stop the vehicle immediately if noise
occurs that could indicate chain breakage. Remove the
damaged parts of the chain before further use.
•Install chains on the front wheels as tightly as possible and
then retighten after driving about1⁄2mile (0.8 km).
•Do not exceed 45 mph (70 km/h).
•Drive cautiously and avoid severe turns and large bumps,
especially with a loaded vehicle.
•Do not drive for prolonged period on dry pavement.
•Observe the tire chain manufacturer’s instructions on the
method of installation, operating speed, and conditions for
use. Always use the lower suggested operating speed of the
chain manufacturer if different than the speed recom-
mended by the manufacture.
NOTE:In order to avoid damage to tires, chains, and
your vehicle do not drive for a prolonged period of time
on dry pavement. Observe the tire chain manufacturer’s
instructions on method of installation, operating speed,
and conditions for usage.
Always use the lower suggested operating speed if both
the chain manufacturer and vehicle manufacture suggest
a maximum speed. This notice applies to all chain
traction devices, including link and cable (radial) chains.
SNOW TIRES
Some areas of the country require the use of snow tires
during winter. Standard tires are of the all season type
and satisfy this requirement as indicated by the M+S
designation on the tire side wall.
If you need snow tires, select tires equivalent in size and
type to the original equipment tires. Use snow tires only
in sets of 4, failure to do so may adversely affect the
safety and handling of your vehicle.
340 STARTING AND OPERATING

WARNING!
Because the front wheels drive and steer the vehicle,
it is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition
can result if either rating is exceeded. You could lose
control of the vehicle and have an accident.
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.
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.

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.
•When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.

the black arrow on the bottom of the filter frame with the
direction of airflow (away from the blower motor and
towards the center of the car).
Refer to the“Maintenance Schedules”section of this
manual for the recommended air conditioning filter
replacement intervals.
Power Steering—Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through a certified
DaimlerChrysler Dealership.
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to insure accurate fluid level reading. Do
not overfill. Use only manufacturers recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to Fluids, Lubricants, and Genuine Parts
for correct fluid type.
Front Suspension Ball Joints
The front suspension ball joints are permanently sealed.
No regular maintenance is required for these compo-
nents.
412 MAINTAINING YOUR VEHICLE

•Check all lights and all other electrical items for correct
operation.
At Each Oil Change
•Change the engine oil filter.
•Inspect the exhaust system.
•Inspect the brake hoses.
•Inspect the CV joints and front suspension compo-
nents.
•Check the automatic transmission fluid level.
•Check the coolant level, hoses, and clamps.
