176 Controls in detailAutomatic transmissionThe following instructions describe opera-
tion of the steering wheel gearshift control
when driving in the automatic program
modeC orS.
For instructions on operating the steering
wheel gearshift control and gear selector
lever in the program mode MANUAL, see
“Manual shift program
(SL55AMGandSL65AMG only)”
(page 177).Downshifting
Briefly pull left shift paddle1
(page 175).
The transmission will shift to the next
lower gear as permitted by the shift
program. This action simultaneously limits
the gear range of the transmission
(
page 172).Upshifting
Briefly pull right shift paddle2
(page 175).
The transmission will shift to the next
higher gear as permitted by the shift
program. This action simultaneously
extends the gear range of the transmission
(
page 172).
Canceling gear range limit
Pull and hold right shift paddle2
(page 175) until
D reappears in the
right multifunction display.
The transmission will shift from the current
gear range directly to gear rangeD.
Shifting into optimal gear range
Pull and hold left shift paddle1
(page 175).
The transmission will automatically select
the gear range suited for optimal
acceleration and deceleration. This will
involve shifting down one or more gears.
i
You cannot shift with the steering wheel
gearshift paddle when the gear selector lever is
in positionP,N orR.
The last selected program mode (CorS) is
switched on when the engine is restarted.
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.

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.

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.

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

Warning!
G
The auto-dimming function does not react if
incoming light is not aimed directly at sen-
sors in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, if the wind screen is in-
stalled.
Light hitting the mirror(s) at certain angles
(incident light) could blind you. As a result,
you may not be able to observe traffic con-
ditions and could cause an accident.
Warning!
G
In case of an accident liquid electrolyte may
escape from the mirror housing if the mirror
glass breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.
Warning!
G
Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
terior rear view mirror or glance over your
shoulder before changing lanes.!
Electrolyte drops coming into contact with
the vehicle paint finish can be completely re-
moved only while in the liquid state by applying
plenty of water.

The rear window defroster cannot be
switched on when the retractable hardtop is
open. The indicator lamp will start flashing if the
hardtop is open.
Close the retractable hardtop.
The rear window defroster can then be switched
