2009 DODGE CHARGER brake

of hitches are the most popular on the market today and
they are commonly used to tow small- and medium-
sized trailers.
Weight-Distributing Hitch
A weight-distributing system works by applying lever-
age through spring (load) bars. They are typically used
for heavier loads to distribute trailer tongue weight to the
tow vehicle’s front axle and the trailer axle(s). When used
in accordance with the manufacturer’s directions, it pro-
vides for a more level ride, offering more consistent
steering and brake control thereby enhancing towing
safety. The addition of a friction / hydraulic sway control
also dampens sway caused by traffic and crosswinds and
contributes positively to tow vehicle and trailer stability.
Trailer sway control and a weight distributing (load
equalizing) hitch are recommended for heavier Tongue
Weights (TW) and may be required depending on vehicle
and trailer configuration / loading to comply with Gross
Axle Weight Rating (GAWR) requirements.
WARNING!
•An improperly adjusted weight distributing hitch
system may reduce handling, stability, braking
performance, and could result in an accident.
•Weight distributing systems may not be compat-
ible with surge brake couplers. Consult with your
hitch and trailer manufacturer or a reputable rec-
reational vehicle dealer for additional
information.
Trailer Hitch Classification
Your vehicle may be factory equipped for safe towing of
trailers weighing over 2,000 lbs (907 kg) with the optional
Trailer Tow Prep Package. See your authorized dealer for
package content.
344 STARTING AND OPERATING

WARNING! (Continued)
Make certain that the load is secured in the trailer
and it 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, suspen-
sion, chassis structure, or tires.
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
•Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle automatic transmission in
PARK. Always, block orchockthe trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. Max loading as defined on the “Tire and Loading
Information” placard.
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized.
(This requirement may limit the ability to always
achieve the 10% to 15% range of tongue weight as a
percentage of total trailer weight.)

Towing Requirements — Tires

Do not attempt to tow a trailer while using a compact
spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires–General Information” in this section for infor-
mation on tire pressures and 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 “Tires–General Infor-
mation” in this section for information on tread wear
indicators and for the proper inspection procedure.
When replacing tires, refer to “Tires–General Informa-
tion” in this section for information on replacement
tires and for the 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).
350 STARTING AND OPERATING

CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes, and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
Do not connect trailer brakes to your vehicle’s hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have an accident.
Towing any trailer will increase your stopping dis-
tance. When towing, you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in an accident.
Towing Requirements — Trailer Lights and Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a 4- and 7-pin
wiring harness. Use a factory approved trailer harness
and connector.
NOTE:Do not cut or splice wiring into the vehicles
wiring harness.

The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.

Preparations For Jacking
6. Park the vehicle on a firm level surface as far from the
edge of the roadway as possible. Avoid icy or slippery
areas.
7. Set the parking brake.
8. Place the shift lever into PARK.
9. Turn OFF the ignition.
10. Turn on the Hazard Warning flashers.11. Block the front and rear of the
wheel diagonally opposite of the jack-
ing position. For example, if changing
the right front tire, block the left rear
wheel. NOTE:
Passengers should not remain in the vehicle
when the vehicle is being jacked.
Jacking and Changing a Tire
WARNING!
Carefully follow these tire changing warnings to
help prevent personal injury or damage to your
vehicle:
•Always park on a firm, level surface as far from
the edge of the roadway as possible before raising
the vehicle.
•Block the wheel diagonally opposite the wheel to
be raised.
•Set the parking brake firmly and set an automatic
transmission in PARK; a manual transmission in
REVERSE.

360 WHAT TO DO IN EMERGENCIES

NOTE:The battery is stored under an access cover in
the trunk. Remote battery terminals are located in the
engine compartment for jump-starting.
1. Wear eye protection and remove any metal jewelry
such as watchbands or bracelets that might make an
inadvertent electrical contact.
2. When boost is provided by a battery in another
vehicle, park that vehicle within booster cable reach, but
do not allow the vehicles to touch one another.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result. 3. Set the parking brake, place the automatic transmis-
sion in PARK, and turn the ignition switch to the LOCK
position on both vehicles.
4. Turn off the heater, radio, and all unnecessary electri-
cal loads.
5. Connect one end of the jumper cable to the remote
jump-start positive battery post
(+)in the engine com-
partment. Connect the other end of the same cable to the
positive terminal of the booster battery. Refer to the
following illustration for jump-starting connections.
6. Connect the other cable, first to the negative terminal
of the booster battery and then to the engine ground (-)
of the vehicle with the discharged battery. Make sure
you have a good contact on the engine ground. Refer to
the following illustration for jump-starting connections.
