Lock of ignition and engine start


Ignition lock

Petrol engines

1–ignition is switched off / the engine does not work, the steering wheel can be locked
2–ignition in
3–engine start

a detachment and the subsequent connection of the accumulator wait for about 5 seconds and only then get the engine.

Diesel engines
giving the fuel / engine is stopped does not work, the steering wheel can be locked
provision of inclusion of preheat and subsequent movement
At the moment of preheat do not include powerful consumers of a current not to overload the accumulator.
engine start

Recommendations for all cars:

Situation 1:

For locking of a wheel take out a key from the lock and turn a wheel before its heard fixing.
On cars with an automatic transmission the key can be turned in situation 1 and to take only when finding the lever of the selector in the situation "R".

On cars from RKPP a key take from the lock only after a full stop! Otherwise probably inadvertent zashchelkivaniye of a wheel on the lock.

Situation 2:

If the key turns hardly or does not turn at all in this situation, it is necessary to turn a little a steering wheel for release of the lock of a wheel.

Situation 3:

Before each subsequent start of the engine return the ignition key in situation 1. Restart blocking in the lock of ignition prevents starter damage, excepting gearing of its gear wheel with a gear wreath of a flywheel at already working engine.

Engine start

General provisions


At the engine working in closed rooms there is a danger of poisoning!

Before start of the engine establish the switching lever in neutral situation (the lever of the selector of an automatic box in the situation "R" or "N") and tighten the hand brake.

On the car from RKPP at the moment of start of the engine squeeze out a coupling pedal that the starter turned only the engine.
As soon as the engine was got, release a key – the starter should not rotate together with the crankshaft.

After cold start the engine some time works with the strengthened noise, the necessary pressure of oil in system of hydrocompensation of a gap of valves yet will not be established. This normal phenomenon which should not cause alarm.
Do not warm up the engine idling! At once begin movement!

Avoid the raised turns and movement with completely squeezed out pedal of an accelerator before achievement of working temperature of the engine.

The car with the catalytic converter cannot be got the towage exceeding 50 м*. Not burned down fuel can get to the converter and lead to its damage.

*Это does not treat cars with the diesel engine.

Petrol engines

At start of the cold or heated-up engine to working temperature do not press a pedal of an accelerator neither before starter inclusion, nor during its work.

If the engine was not got at once, about 10 seconds later stop attempt of start and repeat it approximately in half-minute.
After start of very hot engine the easy pressing an accelerator pedal can be demanded.

Diesel engines


The engine is equipped with preheat system. Necessary time of preheat is determined by burning of a control lamp of the preheat connected to the sensor of temperature of cooling liquid – address to subsection Control and measuring devices. Precautionary and diagnostic systems.

Turn a key in the ignition lock in situation 2. At the cold engine the control lamp of system of preheat that testifies to inclusion of preheat of the engine lights up. It dies away after achievement of temperature of ignition.

In preheat do not include powerful consumers of a current in vain not to overload the accumulator.
At start of the heated-up engine to working temperature, and also at air temperature above +8°С the control lamp of system of preheat lights up approximately for one second – the engine can be got at once.
The engine get at once as soon as the control lamp will go out.

At start do not press an accelerator pedal.

At emergence of separate flashes continue to hold a starter included some more seconds (at most half-minute) while the engine will not earn independently.

If the engine is not got, sustain a pause approximately in half-minute, once again execute preheat and repeat start as it is described above.
