Manual shift program (SL 55 AMG and SL 65 AMG only)
In addition to the automatic shift
programC orS, your vehicle is equipped
with the manual shift program MANUAL.
In the MANUAL program mode,
system-controlled automatic gearshifting
is switched off and you need to change the
gears by manually upshifting or downshift-
ing using the steering wheel gearshift pad-
dles (
page 175) or the gear selector
lever.The program mode selector switch is
located on the lower part of the center
console.

MANUAL For manual gear shifting
C Comfort For comfort driving
S Sport For standard drivingThe current gear selector lever position
and the selected program mode (
M/C/S)
are indicated in the right multifunction
display (

!
Allow engine to warm up under low load use.
Do not place full load on the engine until the op-
erating temperature has been reached.
Shift into reverse gearR or parking positionP
only when the vehicle is stopped.
Avoid spinning of a drive wheel for an extended
period when driving off on slippery road
surfaces. This may cause serious damage to
the drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.

Press program mode selector
switch1 repeatedly until the
M for
MANUAL program mode appears in
the right multifunction display.
The transmission switches to the
MANUAL program mode. Automatic
shifting is switched off. The gear range
is not limited.
You can change the gears manually when
the gear selector lever is in positionD. You
can upshift or downshift through the gears
in succession.Upshifting
Briefly press the gear selector lever to
the right in theD+direction.
or
Briefly pull right shift paddle2
(page 175).
The transmission shifts to the next
higher gear.If, instead of the manual program mode
symbol
M, the symbolp appears in the
right multifunction display (
page 169),
shift to the next higher gear. The fuel
supply will otherwise be interrupted to
prevent the engine from overrevving.
i
The MANUAL program mode will not be
stored. When the engine is turned off with the
MANUAL program mode selected, the transmis-
sion will go to the automatic program mode
(CorS) when the engine is restarted.
!
In the MANUAL program mode, the trans-
mission will not upshift, even if the engine has
reached its overrevving range. Shift up to the
next gear before the engine has reached its over-
revving range. Make absolutely certain that the
engine speed does not reach the red marking on
the tachometer (
page 26). Otherwise the en-
gine could be damaged which is not covered by
the Mercedes-Benz Limited Warranty.
i
If you have selected the AMG menu in the
control system and the engine reaches the over-
speed range in the manual shift program, the col-
or of the display will switch to red and
UP
appears after the gear indicator, advising you to
upshift.

Downshifting
Briefly press the gear selector lever to
the left in theD-direction.
or
Briefly pull left shift paddle1
(page 175).
The transmission shifts to the next
lower gear.Kickdown
Using the kickdown when driving in the
MANUAL program mode is not possible.
Deactivating manual shift program
Press the program mode selector
switch (
page 177) repeatedly
until
Cor

multifunction display.
or
Restart the engine.
The transmission will go to the
automatic program mode (C orS).
The MANUAL program mode is not
stored.Emergency operation
(Limp-Home Mode)
If vehicle acceleration becomes less re-
sponsive or sluggish or the transmission
no longer shifts, the transmission is most
likely operating in limp-home (emergency
operation) mode. In this mode only second
gear and reverse gear can be activated.
Stop the vehicle in a safe location.
Move gear selector lever toP.
Turn off the engine.
Wait at least 10 seconds before
restarting.
Restart the engine.
Move gear selector lever to drive
positionD (for second gear) or reverse
gearR.
Have the transmission checked at an
authorized Mercedes-Benz Center as
soon as possible.
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.i
When you brake or stop, the transmission
shifts down to a gear from which you can easily
accelerate or take off.

You can activate the cruise control when
the vehicle speed is above
20 mph (30 km/h).
In the following cases you cannot activate
the cruise control:
when you brake
when you have set the parking brake
when the gear selector lever is set to
position P, R, or N
when the ESP
® is switched offSetting current speed
Accelerate or decelerate to the desired
speed.
Briefly lift the cruise control lever in
direction of arrow1 or depress in
direction of arrow2.
The current speed is set.
Remove your foot from the accelerator
pedal.
The cruise control is activated.
The currently set speed appears in the mul-
tifunction display.
Warning!
G
The cruise control brakes automatically so
that the set speed is not exceeded.
Keep in mind that the cruise control is a con-
venience system designed to assist the driv-
er during vehicle operation. The driver is and
must always remain responsible for the ve-
hicle’s speed and for safe brake operation.
i
The vehicle speed displayed in the speedom-
eter can briefly vary from the speed setting for
the cruise control system.
i
On uphill grades, the cruise control may not
be able to maintain the set speed. Once the
grade eases, the set speed will be resumed.
On downhill grades, the cruise control maintains
the set speed by braking with the vehicle’s brake
system. In addition, on longer downhill grades
the automatic transmission will downshift auto-
matically.

.
The distance to slower moving vehicles in front
of you will not be set. Your vehicle speed will
then be determined only by the accelerator
pedal position.
i
Depressing the accelerator pedal does not
deactivate Distronic. After brief acceleration
(e.g. for passing), the cruise control will resume
the last speed set.

When you use the cruise control lever to de-
celerate, the brakes will be applied to support
deceleration.
In addition, the transmission will automatically
downshift on long downhill grades.

334 Practical hintsWhat to do if …Problem
Possible cause/consequence
Suggested solution
-
The yellow ABS indicator lamp
comes on while driving.
The ABS has detected a malfunction and has
switched off. The BAS and the ESP
® are also
switched off (see messages in display).
The electro-hydraulic brake system is still
functioning normally but without ABS avail-
able.
If the ABS control unit is malfunctioning, oth-
er systems such as Parktronic*, Distronic*,
or the automatic transmission may also be
malfunctioning.
Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.
Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
Failure to follow these instructions in-
creases the risk of an accident.
Read and observe messages in the
display (
page 347).
The charging voltage has fallen below
10 volts and the ABS was switched off.
The battery may not be sufficiently charged.
Switch off electrical consumers that
are currently not needed, e.g. seat
heating.
If necessary, have the generator and
battery checked.
When the voltage is above this value
again, the ABS is operational again.
