accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again.

Remove your foot from the accelerator pedal.
The first time cruise control is activated, it
stores the current speed or regulates the
speed of the vehicle to the previously stored
speed.
Setting a speed
Bear in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the set speed.
X
Press the cruise control lever up
:
for a
higher speed or down
?
for a lower speed.
X
Keep the cruise control lever pressed until the
desired speed is reached.
X
Release the cruise control lever.
The new speed is stored.

To adjust the set speed in 1 km/h incre-
ments: briefly press the cruise control lever
up
:
or down
?
to the pressure point.
The last stored speed increases or decreases
in 1 km/h increments.
X
To adjust the set speed in 10 km/h incre-
ments: briefly press the cruise control lever
up
:
or down
?
beyond the pressure point.
The last stored speed increases or decreases
in 10 km/h increments.
i
Cruise control is not deactivated if you
depress the accelerator pedal. For example, if
you accelerate briefly to overtake, cruise con-
trol adjusts the vehicle's speed to the last
speed stored after you have finished overtak-
ing.
Deactivating cruise control
There are several ways to deactivate cruise con-
trol:

SPEEDTRONIC
General notes
SPEEDTRONIC brakes automatically so that you
do not exceed the set speed. Change into trans-
mission position D
-
(

page 132) on long and
steep downhill gradients. This increases recu-
peration in overrun mode. This relieves the load
on the brake system and prevents the brakes
from overheating and wearing too quickly. If you
need additional braking, depress the brake
pedal repeatedly rather than continuously.
i
The speed indicated in the speedometer
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
