System)
Information and operating center for 
vehicle sound and communications 
systems, including the radio and the 
navigation system, as well as other op-
tional equipment (CD changer, tele-
phone, etc.). 
Control system
The control system is used to call up 
vehicle information and to change 
component settings. Information and 
messages appear in the multifunction 
display. The driver uses the buttons on 
the multifunction steering wheel to 
navigate through the system and to ad-
just settings.
Differential locks
On slippery surfaces, differential locks 
prevent one wheel of an axle from spin-
ning while the other wheel stands still, 
resulting in driving force no longer be-
ing transferred.Cruise control
Driving convenience system that auto-
matically maintains the vehicle speed 
set by the driver.

Engine oil viscosity
Measurement for the inner friction (vis-
cosity) of the oil at different tempera-
tures. The higher the temperature an 
oil can tolerate without becoming thin, 
or the lower the temperature it can tol-
erate without becoming viscous, the 
better the viscosity.ESP
(E
lectronic Stability Program)
Improves vehicle handling and direc-
tional stability.
ETD
(E

Device which deploys in certain frontal 
and rear collisions exceeding the sys-
tem’s threshold to tighten the seat 
belts.
