Be sure to use unleaded petrol.
If leaded fuel was added by mistake, the exhaust manifold and catalytic converter must be replaced. Before installing new exhaust system components, the fuel tank must be completely filled with unleaded gasoline at least twice.
Starting a warm engine while moving or towing is not allowed. Use an electric cable to start the engine. Unburned fuel when ignited can lead to overheating of the catalytic converter and its subsequent destruction.
Frequent cold starts following one another should be avoided. Otherwise, unburned fuel accumulates in the catalytic converter, which burns explosively when heated, damaging the converter.
If you have difficulty starting the engine, do not let the starter run for a long time, as fuel is injected during starting. Find and fix the problem, and then start the engine.
If there are interruptions in the operation of the ignition system, do not allow fuel injection when starting the engine until the cause of the malfunction has been determined.
Do not check for spark with the spark plug cap removed.
You cannot perform a balance test by disconnecting the high-voltage ignition wire of one of the cylinders. If you disconnect the high-voltage ignition wire of an individual cylinder - even with a special tester - unburned fuel will get into the catalytic converter.
If the ignition system malfunctions, avoid running the engine at high crankshaft speed. Eliminate the malfunction as soon as possible.
Do not park the vehicle on dry leaves or grass. The exhaust system where the catalytic converter is installed is very hot and heat is emitted even after the engine is turned off.
When filling or topping up engine oil, make sure that the maximum oil level on the dipstick is not exceeded. Otherwise, excess oil may get into the catalytic converter and damage the coating or completely destroy it.
