SPEEDTRONIC
General notes
SPEEDTRONIC brakes automatically so that you
do not exceed the set speed. You must select a
lower gear in good time on long and steep down-
hill gradients, especially if the vehicle is laden or
towing a trailer. By doing so, you will make use of
the braking effect of the engine. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
You can set a variable or permanent limit speed:
variable for speed limits, e.g. in built-up areas
R
permanent for long-term speed restrictions,
R
e.g. when driving with winter tyres fitted

i
may differ slightly from the limit speed stored.
Important safety notes
If you fail to adapt your driving style, SPEED-
TRONIC can neither reduce the risk of an acci-
dent nor override the laws of physics. SPEED-
TRONIC cannot take into account road, weather
or traffic conditions. SPEEDTRONIC is only an
aid. You are responsible for the distance to the
vehicle in front, for vehicle speed, for braking in
good time, and for staying in lane.
If there is a change of drivers, advise the new
driver of the speed stored.
