SPEEDTRONIC
General notes
SPEEDTRONIC brakes automatically so that
you do not exceed the set speed. Change into
a lower gear in good time on long and steep
downhill gradients. Take particular note of
this when driving a laden vehicle. 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 over-
heating and wearing too quickly.
Important safety notes
If you fail to adapt your driving style, SPEED-
TRONIC can neither reduce the risk of an
accident nor override the laws of physics.
SPEEDTRONIC cannot take into account
road, weather or traffic conditions. SPEED-
TRONIC 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 stay-
ing in lane.
If there is a change of drivers, advise the new
driver of the speed stored.
You can set a variable or permanent limit
speed:
variable for speed limits, e.g. in built-up
R
areas
®
permanent for long-term speed restric-
R
tions, e.g. when driving with winter tyres
fitted (
