Running in
New engine
The first 1500 kilometers are the engine break-in period.
For the first 1000 km run
- Speed no more than 3/4 of maximum.
- Do not press the accelerator pedal all the way down.
- Avoid high engine speeds.
- Do not drive with a trailer.
In the period from 1000 to 1500 km
- It is possible to gradually transition to speeds up to maximum and to maximum engine speed.
During the first hours of operation, the engine is characterized by increased internal friction, if compared with the subsequent period, when the rubbing parts are running in to each other. The efficiency of the running-in process largely depends on the driving mode during the first 1,500 km of run.
Also, during the post-running period, engine operation at high speeds is not allowed. The maximum permissible engine shaft speed is the beginning of the red field on the tachometer scale. Switch to a higher gear at the latest after the tachometer needle reaches the red warning field (car with manual transmission). Extremely high engine speeds are blocked automatically.
On cars with a manual transmission, do not allow the engine speed to drop with the transition to an unstable operating mode. Shift to a lower gear in time, before the uniformity of the crankshaft rotation is disrupted.
New tires
Be especially careful during the first 500 km of driving with new tires.
New tyres do not initially provide optimal road grip and therefore need to be run in.
New brake pads
New brake pads must first be run in and therefore do not yet provide optimum friction force for the first 400 km. The associated slight reduction in braking efficiency is compensated by a corresponding increase in the force on the brake pedal.
During the running-in period, avoid heavy braking, especially at very high speeds, as well as braking on steep climbs and descents (for example, passes).
Catalytic converter for cars with gasoline engines
Uninterrupted operation of the exhaust gas neutralization device (catalyst) is of crucial importance for environmentally friendly operation of the vehicle.
- Fill your vehicle with unleaded fuel only.
- Never run the fuel tank dry.
- Do not exceed the maximum engine oil level.
- The maximum towing distance for engine starting is 50 m.
Never run the fuel tank down to empty. A fuel supply failure can cause misfires. This causes mottled fuel to enter the exhaust system. This can cause overheating and damage to the catalytic converter.
If the vehicle was operated in a country where unleaded fuel is not available, then when importing it to a country where a catalytic converter is required, the catalytic converter must be replaced.
Attention
- Due to the possibility of high-temperature heating of the catalytic converter under particularly unfavorable operating conditions, park the vehicle so that the catalytic converter does not come into contact with flammable materials.
- In the area of exhaust pipes, catalytic converters or heat shields, additional materials for underbody protection or against corrosion must not be used under any circumstances. These substances may ignite while driving – risk of fire!
Carefully
- Even a single fill with leaded gasoline leads to a deterioration in the performance of the catalytic converter.
- If during the movement of the car there are interruptions in ignition, a drop in power and deterioration in the uniformity of the engine rotation, then the cause may be a malfunction in the ignition system. In this case, unburned fuel can get into the exhaust system; and from there into the atmosphere. In addition, the catalyst may fail due to overheating. Reduce speed immediately and check the car at the nearest specialized enterprise.
