General Information: Glossary

Term Description
ABS ABS: the ABS is a regulation device in the brake system, that prevents the wheels from locking up while braking. Thereby, directional stability and steering ability are retained.
ACT Active cylinder management (ACT): when driving in the RPM range 1, 400 and 4, 000 RPM and at a speed from up to 130 km/h depending on the gear two of the four cylinders can be perfectly unnoticeably deactivated. On vehicles with active cylinder management (ACT) the fuel consumption and the CO2 emission can be lowered.
all wheel drive clutch now replaces the term "BorgWarner". The correct conditions make this step possible, then the term can be changed in the old documents and they do not require changing.
ASR Anti-Slip Regulation; the ASR that the wheels when slip when driving.
Automatic Transmission Fluid Automatic Transmission Fluid: Gear oil for automatic transmissions.
AU Emissions Test
AUS 32 is the abbreviation for the English term "Aqueous Urea Solution" with 32.5 % urea, see AdBlue® 
AdBlue®  Is a created name. This fluid is also called "NOx reducing agent AUS 32 ", "AUS 32" or for the USA, "Diesel Exhaust Fluid". AdBlue® is a clear water/urea solution, is used for treating exhaust gas and to reduce nitrogen oxide and particles. AdBlue® is a registered trademark of the Automobile Manufacturers Association (VDA) in the USA, Germany, the European Union and other countries. The AdBlue urea solution is not mixed with diesel fuel but rather it has its own tank in the vehicle.
ATF level "Fill height" of ATF in transmission.
BEV Battery Electric Vehicle; Electric Vehicle
CNG Compressed Natural Gas
CO Carbon monoxide: results by incomplete combustion of fuels containing carbon
Common Rail "CR" English term; refers to a shared high-pressure fuel injection line "Rail", that supplies fuel to all cylinders of a respective cylinder bank.

QG0 Vehicles that are "not" equipped at the factory with the components for LongLife service. Time and distance dependent intervals (fixed intervals) apply for maintenance.
QG1 Vehicles equipped at the factory with active LongLife service. That means vehicles have a flexible service interval display and are equipped with the following components:
  • Flexible service interval display inside the instrument cluster
  • Engine oil level sensor
  • Brake pad wear indicator
QG2 LongLife service is not activated at the factory. This means, vehicles have a fixed service interval display (time and distance dependent maintenance intervals) and are equipped with the following components:
  • Fixed service interval display in instrument cluster
  • Engine oil level sensor
  • Brake pad wear indicator
QG3 LongLife service is not activated at the factory. This means, vehicles have a fixed service interval display (time and distance dependent maintenance intervals) and are equipped with the following components:
  • Fixed service interval display in instrument cluster
  • Brake pad wear indicator
