Trailer towage

The general information

In order to avoid infringement of guarantee certificates, strictly follow resulted below recommendations concerning rules of the equipment of hook-on devices and towage of trailers.

Strictly adhere to the schedule of routine maintenance of the car (see the Head of Adjustment and routine maintenance). Do not forget that at use of a vehicle many procedures should be made for trailer towage more often.

At all do not exceed norm of loading of the car. Except the maximum safe loads on bridges (GAWR), such characteristics, as weight loading on the hook-on device, and also weight of all luggage placed in the car and the additional equipment should be considered also. Remember that any weight, placed in/on the trailer as a result conducts to loading increase on the car.

Do not forget that infringement of rules of towage of the trailer can lead to the most serious consequences. Try to adhere stated below recommendations:

  • Watch, that the centre of gravity of the cargo placed in the trailer has been displaced a little forward (so that on the hook-on device of the car it was necessary nearby (10 15) % of full weight gross the trailer. Infringement of the given requirement usually leads to infringement of course stability сцепки at the expense of oscillatory lateral movings of the trailer during movement.
  • Do not connect a hydraulic drive of brake mechanisms of the trailer to a brake contour of the car.
  • The equipment of trailers in weight over 907 kg brakes is a towage indispensable condition.
  • Do not connect electroconducting of alarm running fires of the trailer to the basic plait of electroconducting of the car. Connection should be made with application of a standard plait for the equipment of hook-on devices. Infringement of the given requirement can lead to electric equipment failure, and also reception of serious traumas.
  • Do not overload the car and-or the trailer over admissible norms is can lead to loss of the control over management, decrease in efficiency of functioning of brakes, an overload of bridges, components трансмиссионной to a line, a steering, a suspension bracket and bearing кузовных elements.
  • Watch that the cargo placed in the trailer has been reliably fixed.
  • Use for the car equipment only the firm hook-on devices which installation should be charged to experts of dealer branch of company Chrysler.

Admissible weight characteristics of the trailer

Into full weight gross the trailer (GTW) enter weight actually the trailer, plus weight of the cargo placed in it and the hinged equipment. The most exact way of definition GTW is the premise of completely loaded trailer on automobile scales.

Try, that 60 % of weight of cargo were necessary on a forward part of the trailer that provides requirement performance about that on the hook-on device it was necessary nearby (10 15) % GTW.

Distribution GTW.

At towage of trailers with loading on the hook-on device over 160 kg or when GTW exceeds 1600 kg сцепка should be equipped by the device twist-control also turnbuckle balancing.

Hook-on devices

Hook-on devices of the Class I are intended for towage of trailers with GTW on more than 907 kg. The device always can be got in dealer branches of company Chrysler.

Devices of the Class III suppose towage of trailers in weight gross (GTW) to 2 268 kg.

The car equipped with the hook-on device of the Class IV can be used for towage of trailers with GTW to 2 948 kg.

The weight loading having on the hook-on device should make not less than 10 %, but no more than 15 % GTW and not to exceed at all 340 kg.

Devices of the raised durability

Hook-on devices of Classes III and IV cars of a factory complete set usually consist from established on elements of a frame of a turnbuckle and listed above the necessary equipment. Use of such additional components as the device twist-control, brake mechanisms, the balance weight, низкопрофильные mirrors, etc. strictly is recommended.

Devices of the Class III

As already it was mentioned above, hook-on devices of the Class III are intended for towage of trailers in weight gross GTW) no more than 2 268 kg. For successful towage of such trailers it is necessary to use only the models meeting following requirements:

The engine 6-cylinder, 4.0 l
Transmission Only the automatic
The size of tyres Р215/75R15 (Minimum)
Cooling system The raised productivity
Spare wheel Full-size, usual type, or time Т155/D16
Cooler ATF Installation of an additional cooler is obligatory
Oil of the back bridge Synthetics
Steering The special steering pump and the mechanism with steady against influence of the raised temperatures by epiploons

Devices of the Class IV

The given devices allow to make towage of trailers in weight to 2 948 kg. Should be established on following models:

The engine 8-cylinder, 5.2 l
Transmission Only the automatic
The size of tyres Р225 (Minimum)
Cooling system The raised productivity
Spare wheel Full-size, usual type, or time Т155/D16
Cooler ATF Installation of an additional cooler is obligatory
The transfer relation of the main transfer 3.73:1
Oil of the back bridge Synthetics
Steering The special steering pump and the mechanism with steady against influence of the raised temperatures by epiploons.

Councils about maintenance of optimum operating conditions of system of cooling during trailer towage

In order to avoid engine and transmission overheats try to adhere to following recommendations:

  • During a stop in the conditions of a city cycle translate transmission in neutral position and lift engine turns.
  • At movement on a motorway speed should be slightly more low, than at operation of the car without the trailer.
    c) temporarily disconnect К/В.
  • In time carry out procedures of service of system of cooling (see the Head of Adjustment and routine maintenance).

In order to avoid potential overheat АТ disconnect raising transfer (О/D OFF) at movement on hilly district, or on the most intense sites translate АТ in position 2. In order to avoid superfluous switchings of transmission move on lowered on one step передаче.15 At frequent towage of the trailer by the car equipped АТ (in particular in mountain district or in hot weather composers of the given Management recommend to make change ATF through each 24 000 km (15 000 miles) run and also to equip transmission маслоохладителем (if that is not established фабрично).

1) Towing loading of the car should be lowered at the expense of weight loading on a turnbuckle for the purpose of loading maintenance on the back bridge (GAWR) within 1 338 kg.
2) GCWR = the Full combined weight сцепки.
* Use of hook-on devices of Classes III and IV assumes application on the car of the special steering pump and the steering mechanism with heat resisting epiploons.

At towage of the heavy trailer try to avoid detonations in the engine. In case of occurrence of those reduce loadings in order to avoid damage of pistons.
