If necessary, driving may becontinued for a short time at a low speedand with a low engine speed.Irregular engine running and a loss ofengine power when the ElectronicStability Program (ESP® Plus 3) comesinto action are the result of operatingconditions and are therefore of nosignificance - see page 198.6Catalytic converter for petrol engines 193Catalytic converter for diesel engines 194Controlling exhaust emission.............. 195Exhaust gases ...................................... 196Maintenance ........................................ 1971) LRP = Lead Replacement Petrol.
