3) It is possible to refuel AI 95 with a slight decrease in engine power. AI 91 can only be used in exceptional cases. | |
Diesel engines | |
Diesel fuel according to DIN EN 590 | Cetane number not less than 49 |
Do not use biodiesel (rapeseed oil methyl ester) | |
The cetane number characterizes the ability of diesel fuel to self-ignite. | |
Operation in winter conditions | |
winter diesel fuel, which, depending on its brand, ensures uninterrupted operation of the engine at temperatures down to -15°C or down to -22°C. | |
Fuel filter heater | |
The vehicle is equipped with a fuel filter heater. Due to this, fuels designed for use at temperatures down to -15°C can be used at temperatures down to approximately -25°C. | |
From -9 to -15°C | 10% |
From -15 to -25°С | 30% |
Below -25°С | 50% |
When the outside air temperature drops below -20°C towinter diesel fuel, add a viscosity reducer or kerosene (in % of total volume) | |
From -20 to -26°C | 10% |
From -26 to -31°С | 30% |
Below -31°С | 50% |
Fuel tank capacity | |
Volume | 63 l |
including reserve stock | 8 l |

The fuel system consists of a fuel tank, fuel lines, a filter, a fuel pump and a fuel injection system.
The fuel tank has two chambers. The tank is located under the rear seats. The available fuel supply is shown to the driver on the instrument panel. Moreover, the fuel supply for each chamber is measured by a separate sensor. The microprocessor in the instrument cluster calculates the current fuel content from the injection pulses, driving speed and electrical signals from the lever sensor.
The fuel tank is vented through a closed air removal system. In a gasoline engine, harmful gasoline vapors are collected in an adsorber and fed under control to the engine.
How to drive a car economically
Driving style has a significant impact on fuel consumption. The following are some tips for wise vehicle operation:
- Drive away immediately after starting the engine, even if it is in the cold.
- When stopping the car for more than 40 seconds, turn off the engine.
- Always drive in the highest possible gear.
- When driving long distances, maintain a steady speed whenever possible. Avoid driving at high speeds. Drive carefully. Don't slow down unnecessarily.
- Do not carry excess cargo on the vehicle. If possible, remove the luggage carrier installed on the vehicle, for example, on the roof.
- Check tire pressure. Avoid excessive pressure reduction.
