* At 2500 rpm, the CO content should not exceed 0.3%.
** When the coolant temperature is above 80°C after the engine has been running steadily at 2500 rpm for approximately 30 seconds. The check should be carried out after the transition to idling.
*** See country-specific specifications for guideline values.
**** Use of unleaded petrol is acceptable. 91.

Elements of the injection system
Table 3.8
Features of the injection system:
- 55-pin computer SIEMENS FENIX 5;
- multi-point injection operating in semi-sequential mode. Pair control of injectors (first injectors for cylinders 1 and 4, then injectors for cylinders 2 and 3):
- static ignition system with two coils;
- solenoid valve for emptying the absorber, controlled by the law of cyclic opening;
- configuring the computer depending on the type of gearbox (mechanical or automatic);
- idling mode correction depending on: the presence of an air conditioner; power steering pressure switch signals; battery voltage;
- signal lamp of the injection system in the instrument panel;
- maximum engine speed: in 1st, 2nd, 3rd gears - 6200 rpm; in 4th, 5th gears - 6000 rpm.
Attention! The use of a second generation anti-theft system requires a special technique for replacing the injection computer.
