Technical characteristics

Engine start with the discharged accumulator

If the engine is not got because of the discharged accumulator, it is not dangerous. Otherwise business is at malfunction in ignition system: in this case not burned down particles of a working mix can ignite and lift in addition temperature in the catalyst to dangerous level.

Engine start by means of an auxiliary wire


    The car with the charged accumulator put at such distance that it was possible to lay an auxiliary wire on the right in an impellent compartment of Audi. Check, whether all consumers of a current are disconnected in your disconnected car. Connect a wire plusovy poles of both accumulators. Other auxiliary wire connect in the beginning to a minus pole of charged another's accumulator, and then to not isolated weight (for example, directly to the engine) in an impellent compartment of the disconnected car. Start the engine of the auxiliary car on the raised turns in order that the generator intensively gave tension. If the engine is not got at once, let's to a starter cool down a little. Again get the auxiliary engine therefore the discharged accumulator will be charged already a little. At a detachment of an auxiliary wire for engine start-up in the beginning remove wires from the minus plug of charged another's accumulator.

Engine start from "pusher"

In the simplest way it is possible to get the engine if to push the car under a bias. If the bias is not present, muscular force will help, but two assistants to push Audi are necessary:


    Include ignition. Put the 1st transfer. On higher transfers the generator is turned too slowly for intensive giving of a current. Press a coupling pedal, push the car while it will not sweep. Quickly include coupling. The engine is sharply turned and should be got. At once press a pedal of coupling and give gas.

Car towage

For towage find the skilled assistant in this question in order that because of a nonprofessional approach not to do still bigger harm. Also remember the following: at the idle engine does not work also servoupravleny and the brake amplifier.


    Include ignition, put the 2nd transfer and wring out a coupling pedal. The towing car should begin movement slowly. Approximately at 15 km/h slowly include coupling, thus the right hand put on the hand brake. If the engine was got, press a pedal of coupling and give gas. Softly pull the hand brake not to drive in the forward car. The driver of the towed car gives a sound signal. Switch off transfer, release a coupling pedal. Brake by means of the hand brake together with towing car.
