* At 2500 rpm, the CO content should not exceed 0.3%.
** At a coolant temperature above 80°C after stable engine operation at 2500 rpm for approximately 30 seconds. Check after switching to idle speed.
***See country specific specifications for normative values.
**** It is permissible to use unleaded petrol of 91 octane grade.

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. Paired control of injectors (first injectors of cylinders 1 and 4, then injectors of cylinders 2 and 3):
- static dual coil ignition system;
- 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);
- correction of idle mode depending on: presence of air conditioning; power steering pressure relay signals; battery voltage;
- injection system warning light in the instrument panel;
- maximum engine speed: 1st, 2nd, 3rd gear - 6200 rpm; in 4th, 5th gears - 6000 rpm.
Attention! Using the second generation anti-theft system requires a special method of replacing the injection computer.
