Anti-locking brake system. The ABS is a regulating system in the brake system, that
prevents locking when braking. This helps to maintain directional stability and steerability.
All-wheel drive Term to be used in place of “Haldex” with immediate effect. Legal implications make this
coupling
step necessary. The term may nevertheless appear in older documents but need not be
replaced.
TCS
Traction control system The TCS prevents the wheels from slipping when the vehicle is
driven off.
ATF
EET
Automatic Transmission Fluid. Gear oil for automatic gearbox.
Exhaust emissions test
AUS 32
AdBlue®
Is an invented name.
This fluid is also referred to as “NOx reducing agent AUS 32”, “AUS 32” or “Diesel Exhaust
Fluid” (in the US).
AdBlue® is a colourless reducing agent that is used for exhaust post-treatment in order
to reduce nitrous oxides and particulates.
AdBlue® is a registered trademark of the VDA (Verband der Automobilindustrie - German
association of the automotive industry) in the USA, Germany, the European Union and
other countries.
The AdBlue urea solution is not mixed with diesel fuel, but is carried in a separate tank
in the vehicle.

Common rail
“CR”
This term refers to a common high-pressure injection line, the “rail”, which supplies all
cylinders of the relevant cylinder bank with fuel.

Vehicles are “not” factory-fitted with components for LongLife service. For maintenance,
the intervals based on time and distance (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 lining wear indicator
QG2
The LongLife service is not factory-activated. This means vehicles have a fixed service
interval display (time and mileage dependent service intervals): These vehicles are fitted
with the following components:
♦ Non-flexible service interval display in dash panel insert
♦ Engine oil level sensor
♦ Brake lining wear indicator
QG3
®
The LongLife service is not factory-activated. This means vehicles have a fixed service
interval display (time and mileage dependent service intervals): These vehicles are fitted
with the following components:
♦ Non-flexible service interval display in dash panel insert
♦ Brake lining wear indicator

SAE
SCR
Society of Automotive Engineers. Association which creates proposals/guidelines for im‐
plementing legal requirements (e.g. standards).
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.
