The lock of ignition and engine start


The ignition lock

Petrol engines

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

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

Diesel engines
Fuel giving / the engine is stopped does not work, the steering wheel can be locked
Position of inclusion of preheat and the 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:

Position 1:

For wheel lock-out 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 position 1 and to take only at a finding of the lever of the selector in position “Р”.

On cars with РКПП a key take from the lock only after a full stop! Otherwise probably inadvertent защелкивание a wheel on the lock.

Position 2:

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

Position 3:

Before each subsequent start of the engine return the ignition key in position 1. Restart blocking in the ignition lock 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 premises there is a danger of a poisoning!

Before engine start establish the switching lever in neutral position (the lever of the selector of an automatic box in position “Р” or “N”) and tighten a manual brake.

On the car with РКПП at the moment of engine start 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 коленвалом.

After cold start the engine some time works with the strengthened noise, the necessary pressure of oil in system of hydroindemnification of a backlash of valves will not be established yet. 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 catalytic the converter cannot be got the towage exceeding 50 м*. Not burnt down fuel can get to the converter and lead to its damage.

*Это does not concern 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, after nearby 10 seconds stop attempt of start and repeat it approximately in half-minute.
After start of very hot engine easy pressing an accelerator pedal can be demanded.

Diesel engines


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

Turn a key in the ignition lock in position 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 that it is 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 occurrence of separate flashes continue to keep a starter included some more seconds (as much as possible 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.
