- Starting a cold engine;
- Frequent starting and stopping;
- Trailer towing;
- Movement in mountainous/hilly terrain;
- Driving on roads with poor surface quality;
- Severe air pollution;
- Large dust content of the air and the presence of sand in it;
- Frequent use of the circulation mode;
- Vehicle operation in high altitude conditions;
- Large temperature fluctuations.
Severe operating conditions for the brake system:
- Frequent braking when driving at high speeds;
- Braking of the most loaded car;
- Functioning on models equipped with AT;
- Movement in mountainous terrain;
- Driving on roads covered with water, snow, mud and dust.
In addition, for diesel models equipped with a particulate filter (DPF), severe operating conditions is the movement in the conditions of the urban cycle. This requires more frequent regeneration of the DPF and shorter engine oil change intervals.
Vehicles with low intensity of use - the average daily mileage is 10 km or more than 30% of the time the engine is idling (e.g. special police cars or taxis) - an additional replacement of engine oil and an oil filter is required if an oil of lower quality than the ACEA-AZ / VZ standard is poured into the system.
Oil change interval:
- When using ACEA-A2 / B2 engine oil, the oil change interval under severe operating conditions is reduced to 7500 km (instead of 15000 km).
- If only API SJ/SL engine oils are available, the oil change interval is reduced to 7,500 km, regardless of operating conditions.
