Warning: There is a danger of poisoning when the engine is running in a closed room!
Put the shift lever in neutral before starting the engine (with an automatic transmission, set the selector to the position "R" or "N") and securely apply the parking brake.
On a car with a manual transmission, while starting the engine, depress the clutch pedal - the starter should only rotate the engine crankshaft.
As soon as the engine starts, immediately release the ignition key - the starter must not rotate with the engine.
After starting a cold engine, it will work with increased noise for a short time, since the oil pressure in the valve clearance hydraulic compensators is not yet high enough. This is normal and should not worry you.
Do not allow a warm engine to run when parked! Switch off immediately!
Until the engine has warmed up to normal operating temperature, avoid running it at high speeds and full throttle.
When towing vehicles with an exhaust gas purification catalytic converter, do not continue to attempt to start the engine beyond a towing distance of more than 50 m. Unburned fuel may enter the catalytic converter and damage it.
Before trying to start the engine by towing, you should try to start it using the battery of another vehicle.
Gasoline engines
These engines are equipped with a fuel injection system that automatically ensures the optimum ratio between fuel and air at any outside temperature.
Before starting a cold or warm engine and during start-up, do not press the accelerator pedal.
If you cannot immediately start the engine, you should suspend the starting process after 10 seconds and repeat it after half a minute.
If the engine still does not start, check the fuel pump motor fuse.
After starting a very hot engine, let it run at medium speed for a while.
Diesel engines
Preheating device
After switching on the driving position ("Ignition on") the control lamp, depending on the temperature of the engine coolant, signals or does not signal the need for preheating.
Starting a cold engine
At outside temperatures above +5°C: the engine can be started immediately without preheating. During starting, do not press the accelerator pedal.
When the outside temperature is below +5°С: turn the key in the ignition switch to position 2 – the preheating control lamp will light up. The lamp will go out after reaching a temperature sufficient to ignite the fuel.
When the preheating is on, all other large current consumers must be turned off - otherwise the battery will be overloaded with a large current.
Start the engine immediately after turning off the warning lamp.
During starting, do not press the accelerator pedal.
If the ignition of the fuel in the engine is still unstable, allow the starter to run for a few more seconds (no more than half a minute), until the engine can run on its own.
If the engine does not start, turn on the preheat again and then try to start the engine again as described above. If the engine still does not start this time, check the preheater fuse - it may have blown.
Starting the engine warmed up to operating temperature
The preheating control lamp does not light up - the engine can start immediately.
Starting the engine after running out of fuel from the fuel tank
If the fuel tank of a diesel vehicle has been completely depleted, it may take longer than usual to start the engine after refueling, up to one minute. The reason is that the fuel supply system can only be freed from the air in it during the engine start process.
