Chrysler 300/300 Touring/300C, Dodge Magnum. Manual — part 139
•
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.
− 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 (Refer to 22 - TIRES/
WHEELS/TIRES - DESCRIPTION) section of this manual on Tread Wear Indicators for the proper inspection pro-
cedure.
− When replacing tires refer to (Refer to 22 - TIRES/WHEELS/TIRES - DESCRIPTION) 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 con-
troller 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).
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 hydraulic brake lines. It can overload your brake system 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 distance. 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 & Wiring
Whenever you pull a trailer, regardless of the trailer size, stop lights 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.
Refer to the following illustrations.

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
Towing Tips - Automatic Transmission
The “D” range can be selected when towing. However,
if frequent shifting occurs while in this range, the “3”
range should be selected.Using the “3” range while
operating the vehicle under heavy operating conditions
will improve performance and extend transmission life
by reducing excessive shifting and heat build up. This
action will also provide better engine braking.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more
than 45 minutes of continuous operation. See Sched-
ule “B” in section 8 of this manual for transmission
fluid change intervals.
NOTE: Check the automatic transmission fluid
level before towing.
Towing Tips - Electronic Speed Control (If
Equipped)
− Don’t use in hilly terrain or with heavy loads.
− When using the speed control, if you experience speed drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
− Use speed control in flat terrain and with light loads to maximize fuel efficiency.
Towing Tips - Autostick (If Equipped)
− For vehicles equipped with Autostick. By using the Autostick modes, and selecting a specific gear range, fre-
quent shifting can be avoided. The highest gear range should be selected that allows for adequate performance.
For example, choose “4” if the desired speed can be maintained. Choose “3” or “2” if needed to maintain the
desired speed.
− Extended driving at high RPM should be avoided to prevent excess heat generation. A reduction in vehicle
speed may be required to avoid extended driving at high RPM. Return to a higher gear range or vehicle speed
when road conditions and RPM level allows.
Towing Tips - Cooling System
To reduce potential for engine and transmission overheating, take the following actions:
•
City Driving - When stopped for short periods of time, put transmission in neutral and increase engine idle
speed.
•
Highway Driving - Reduce speed.
•
Air Conditioning - Turn off temporarily.
•
refer to Cooling System Operating information in the Maintenance section of this manual for more information.
