sions quality.
OBD-II American onboard diagnosis

QG0 Vehicles are "not" factory-fitted with components for LongLife service. For maintenance,
the time and distance dependent intervals (non-flexible intervals) apply.
QG1 Vehicles are factory-fitted with active LongLife service. This means vehicles have a flex‐
ible service interval display and are fitted with the following components:
♦ Flexible service interval display in dash panel insert
♦ Engine oil level sensor
♦ Brake pad wear indicator
QG2 The LongLife service is not factory-activated. This means vehicles have a non-flexible
service interval display (time and distance dependent service intervals) and are fitted with
the following components:
♦ Non-flexible service interval display in dash panel insert
♦ Engine oil level sensor
♦ Brake pad wear indicator
QG3 The LongLife service is not factory-activated. This means vehicles have a non-flexible
service interval display (time and distance dependent service intervals) and are fitted with
the following components:
♦ Non-flexible service interval display in dash panel insert
♦ Brake pad wear indicator

Readiness code 8-digit binary code which indicates if all exhaust relevant diagnoses have been performed
by the electronic engine management.
RON (Research octane number); measurement unit of the knock resistance of petrol
SPF Particulate filter
RDK, RKA Tyre pressure monitoring
SAE (Society of Automotive Engineers); association which creates proposals/guidelines for
implementing legal requirements (e.g. standards).
SCR With the SCR process (selective catalytic reduction) the noxious nitrogen oxides emis‐
sions are reduced to a great extent and are converted to steam and nitrogen by the urea
solution.
A special urea solution (AdBlue®) is injected into the exhaust system upstream of a spe‐
cial catalytic converter.
SD Naturally aspirated diesel engine
