Important safety notes
G
WARNING
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely.
G
WARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
G
WARNING
SPEEDTRONIC is only an aid designed to
assist driving. You are responsible for the
vehicle's speed and for braking in good time.
G
WARNING
If there is a change of drivers, advise the new
driver of the limit speed stored.
Only use variable SPEEDTRONIC if you will not
have to accelerate suddenly to a speed above
that stored as the limit speed. You could oth-
erwise cause an accident.
You can only exceed the limit speed stored if
you deactivate variable SPEEDTRONIC:
R
using the cruise control lever
R
by depressing the accelerator pedal
beyond the pressure point (kickdown)
It is not possible to deactivate variable
SPEEDTRONIC by braking.
General notes
