GENERAL INFORMATION

Models 14 NV

On models with the engine of 14 NV the corner of an advancing of ignition is adjusted for use of unleaded gasoline of 95 RON. Readjustment on other grade of gasoline is not provided.

If necessary it is possible to use etilirovanny gasoline of 98 RON.

Models 1,6, 1,8 and 2,0 of l of SOHC


Prevention

On models with the catalyst only unleaded gasoline of 95 RON should be used. Even if in the car the cap of octane number of fuel is established, it cannot be switched.


Arrangement of the cap switching octane number of used fuel to models of 2,0 l

PERFORMANCE ORDER
1. Models, except 14 NV, have a cap switching octane number of fuel and located in a back left part of a motor compartment (see drawing).
2. On the one hand caps there is a marking And or 98 which corresponds to the provision of a cap when using etilirovanny gasoline of 98 RON. On the other side of a cap there is a label In or 95 which corresponds to situation for use of unleaded gasoline of 95 RON. Originally all cars are intended for use of unleaded gasoline of 95 RON. If you decided to rearrange a cap on other grade of fuel, previously it is necessary to develop or pump out the remained fuel from a fuel tank.
3. Fill in in a fuel tank the fuel, the corresponding grade.
4. Check that ignition is switched off, then release a bracket and remove a cap defining octane number of fuel.
5. Turn a cap in such situation that marking of octane number appeared from above, then insert a cap on a place and fix a bracket.
6. Pay attention that gasoline with higher octane number can be used, without rearranging a cap.

Models 20 XE, C20 XE and X20 XEV

On these models instead of a cap of installation of octane number of fuel the cap of the moment of ignition is used. The provision of a cap cannot be changed, as it is intended for transfer to the Motronic block of information which has been written down in memory.

On these models there is a sensor of a detonation which in the presence of a detonation in cylinders of the engine reduces a corner of an advancing of ignition. It is necessary to remember that all cars with the catalyst should be maintained only on неэтилиро bathing gasoline.
