Note:
- When operating the vehicle at high altitude (at high altitude) or driving with an unheated engine, the ignition advance angle is slightly increased to ensure optimal engine operation. In addition, when detonation occurs, the ignition advance angle is gradually reduced until the detonation stops.
- When an automatic transmission changes gears, the ignition timing is reduced to reduce engine torque, thus eliminating the car's jerking during gear changes.
The ignition system is contactless and includes:
- (2.0L/2.4L engines) 2 ignition coils for cylinders #1 and #4 and for cylinders #2 and #3 respectively.
- (2.7L engine) 3 ignition coils for cylinders #1 and #4, #2 and #5 and for cylinders #3 and #6 respectively.
Power transistors are built into the engine control unit.
The value of the ignition advance angle changes dynamically in accordance with the engine operating mode (crankshaft speed, load, engine thermal state, etc., determined by signals from various sensors) and data on optimal ignition advance angles (recorded in the memory of the electronic engine control unit).
Note: The procedures for removing, installing and checking spark plugs and spark plug wires are given in Chapter "Maintenance and general check and adjustment procedures".
