Sport Program and manual
operation M/S Shift selector lever from position D
toward the left into the shifting slot M/S:
the Sport Program is activated and D S
appears in the instrument cluster. This
position is recommended for a perfor-
mance-oriented driving style.
Briefly pressing the selector lever
toward the front or rear activates man-
ual operation and Steptronic changes
gears. The following display appears in
the instrument cluster, depending on
the model:
>1 to 5 or 1 to 6
>M1 to M5 or M1 to M6. 530de264
Upshifts and downshifts are executed
only when they will result in a plausible
combination of engine and vehicle
speed; thus, for example, a downshift
that would cause the engine to overrev
will not be executed by the system. The
gear selected will appear briefly in the
instrument cluster and then the current
gear will reappear.
To return to automatic mode, move the
selector lever toward the right into posi-
tion D.
Malfunction
The warning lamp lights up or
the message TRANS.FAILSAFE
PROG appears in the Check
Control. A malfunction has occurred in
the transmission system. Avoid heavy
loads.
Bring the vehicle to a stop. Move the
transmission selector lever to P. Set the
parking brake and switch the engine off
by turning the ignition key to position 0.
Wait a few seconds, then start the
engine.
If the indicator lamp goes out after a
few seconds, normal transmission per-
formance has been restored. You may
continue to drive as usual. If the indica-
tor lamp does not go out, you can place
the selector lever in all positions, but
the vehicle will now only drive forward
with limited gear selection.
Have the system checked as soon as
possible.

starting and towing begins on

Fold-out positionThe left wiper is partially concealed by
the hood. To bring the wipers to roughly
a vertical position, which is important
when changing the wiper blades or
when folding the wipers out during
frosty weather, for example, proceed as
follows:
>With the lever in position 1, switch off
the ignition as soon as the wipers
come to a stop.
If equipped with a rain sensor:
1. Switch on the wipers with the lever in
position 1, 2 or 4
2. When the wipers are roughly vertical,
switch the ignition off.
For changing the wiper blades, refer to
page160.
Fold the wipers back down onto
the windshield before you turn the
ignition key to position 1 or 2 again. If
you do not, they could be damaged.<
Intermittent mode Not provided in vehicles with rain sen-
sor.
You can set the wipe interval to four
stages with the knurled wheel 7.
In addition, the wipe interval is varied
automatically depending on road
speed. Rain sensor The rain sensor automatically controls
the wiper operation as a function of the
rain intensity. It is located on the wind-
shield, directly in front of the interior
rearview mirror.
To activate the rain sensor:
Move the lever to position 1 as of igni-
tion key position 1. The wipers travel
once across the windshield, regardless
of the weather conditions.
You can leave the lever permanently in
position 1. It is then only necessary to
activate the rain sensor as of ignition
key position 1.
To do this, turn the knurled wheel 7
briefly.

To adjust the sensitivity of the rain
sensor:
Turn the knurled wheel 7.
To deactivate the rain sensor:
Move the lever to position 0.
Deactivate the rain sensor when
passing through an automatic car
wash. Failure to do so could result in
damage caused by undesired wiper
activation.< Normal wipe The system switches automatically to
intermittent mode when the vehicle is
stationary, not on vehicles with rain
sensor. Fast wipe The wipers operate at normal speed
when the vehicle is not moving, not on
vehicles with rain sensor. Windshield washing The system sprays washer fluid against
the windshield and activates the wipers
for a brief period.
Special wash program
*
As with 5; several additional wash
cycles are carried out and the head-
lamps are cleaned
*.
This program is recommended after you
have driven on extremely dirty roads.
Headlamp washing
*
>With the special wash program 6
>At appropriate intervals, the head-
lamps will also be cleaned upon actu-
ation of the windshield washer func-
tion 5 while the vehicle's headlamps
are switched on.
Do not use the washers if there
is any danger that the fluid will
freeze on the windshield. If you do so,
your vision could be obscured. Use
antifreeze to prevent this, refer to
page152.
Do not actuate washer systems when
the fluid reservoir is empty, otherwise,
the washer pump will be damaged.<
Windshield washer nozzles The windshield washer jets are heated
automatically when the ignition key is in
position 2.

approx. 20 mph/30 km/h.
You can use cruise control whenever
the system is active while the engine is
running.
On the sports steering wheel
*, there
are +/– buttons on the right side of the
steering wheel for the cruise control.
Do not use the cruise control
when unfavorable conditions do
not permit driving at constant speed.
Otherwise you could lose control of the
vehicle and cause an accident. These
unfavorable conditions include winding
roads, heavy traffic or poor road condi-
tions, e.g. snow, rain, ice or a loose
road surface.<
