Manual shift program S 55 AMG
In the manual program modeM you can 
change the gears manually on the steering 
wheel (
page 181) or by using the gear 
selector lever (
page 175).The program mode selector switch is 
located on the lower part of the center 
console.
1Program mode selector switch
M Manual For manual gear shifting
C Comfort For comfort driving
S Sport For standard driving
The current gear selector lever position 
and the selected program mode (
M/C/S) 
are indicated in the tachometer display 
(
page 174).Activating manual shift program
Press program mode selector 
switch1 repeatedly until the
M for the 
manual program modeM appears in 
the tachometer display.
The transmission switches to the 
manual program modeM. 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.
!Allow engine to warm up under low 
load use. Do not place full load on the 
engine until the operating 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.

Briefly press the gear selector lever to 
the left in theD-direction 
(page 175).
or
Press button1 on the left side of the 
steering wheel (
page 181).
The transmission shifts to the next 
lower gear.Upshifting
Briefly press the gear selector lever to 
the right in theD+direction 
(page 175).
or
Press button2 on the right side of the 
steering wheel (
page 181).
The transmission shifts to the next 
higher gear. Kickdown
The kickdown can also be used for 
maximum acceleration when driving in the 
manual program modeM.
Press the accelerator past the point of 
resistance.
The transmission shifts to a lower gear.
Shift up once the desired speed has 
been reached.
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.iWhen you brake or stop, the transmis-
sion shifts down to a gear from which 
you can easily accelerate or take off.
iWhen driving at full throttle, the trans-
mission shifts to the next higher gear 
when maximum engine speed has been 
reached.

Deactivating manual shift program
Press the program mode selector 
switch (

Restart the engine.
The transmission will go to the 
automatic program mode (C orS).
The manual program modeM is not 
stored.Emergency operation (Limp Home 
Mode)
If vehicle acceleration worsens or the 
transmission no longer shifts, the trans-
mission 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.
Move gear selector lever toP.
Turn off the engine.
Wait at least ten seconds before 
restarting.
Restart the engine.
Move gear selector lever to positionD 
(for second gear) orR.
Have the transmission checked at an 
authorized Mercedes-Benz Center as 
soon as possible.

Remove your foot from the accelerator 
pedal.
The selected speed appears in the multi-
function display for approximately five sec-
onds, and the corresponding speedometer 
segments from the selected speed to the 
vehicle maximum speed are illuminated.
iDepressing the accelerator pedal does 
not deactivate cruise control. After 
brief acceleration (e.g. for passing), 
cruise control will resume the last 
speed set.
iWhen you use the cruise control lever 
to decelerate, the transmission will au-
tomatically downshift if the engine’s 
braking power does not brake the vehi-
cle sufficiently.
Warning!
G
The speed stored in memory should only be 
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration 
differences arising from returning to the pre-
set speed could cause an accident and/or 
serious injury to you and others.

Confirm the garage door operation by 
pressing the programmed integrated 
signal transmitter button (2, 3 
or4). 
Step 13:
To program the remaining two buttons, 
repeat the steps above starting with 
step 3.Gate operator/Canadian programming
Canadian radio-frequency laws require 
transmitter signals to “time-out” (or quit) 
after several seconds of transmission 
which may not be long enough for the inte-
grated signal transmitter to pick up the sig-
nal during programming. Similar to this 
Canadian law, some U.S. gate operators 
are designed to “time-out” in the same 
manner. 
If you live in Canada or if you are having dif-
ficulties programming a gate operator (re-
gardless of where you live) by using the 
programming procedures, replace step 4 
with the following:Step 4:
Continue to press and hold the inte-
grated signal transmitter button (2, 
3 or4) while you press and re-press 
(“cycle”) your hand-held remote con-
trol transmitter6 every two seconds 
until the frequency signal has been 
learned. Upon successful training, the 
indicator lamp1 will flash slowly and 
then rapidly after several seconds.
Proceed with programming step 5 and 
step 6 to complete.

Passenger compartmentDriving abroad
Abroad, there is an extensive 
Mercedes-Benz service network at your 
disposal. If you plan to drive into areas 
which are not listed in the index of your 
Mercedes-Benz Center directory, you 
should request pertinent information from 
an authorized Mercedes-Benz Center.Control and operation of radio trans-

!Do not drive through flooded areas or 
water of unknown depth. Before driving 
through water, determine its depth. 
Never accelerate before driving into 
water. The bow wave could force water 
into the engine and auxiliary equip-
ment, thus damaging them.
If you must drive through standing wa-
ter, drive slowly to prevent water from 
entering the passenger compartment 
or the engine compartment. Water in 
these areas could cause damage to 
electrical components or wiring of the 
engine or transmission, or could result 
in water being ingested by the engine 
through the air intake causing severe 
internal engine damage. Any such dam-
age is not covered by the 
Mercedes-Benz Limited Warranty.
Warning!
G
Always fasten items being carried as secure-
ly as possible.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown 
around inside the vehicle, and cause injury 
to vehicle occupants unless the items are 
securely fastened in the vehicle.
The trunk is the preferred place to carry ob-
jects.
Warning!

Please do not forget that your primary re-
sponsibility is to drive the vehicle safely. 
Only operate the COMAND (Cockpit Man-
agement and Data System), radio, or tele-
phone
1 if road, weather and traffic 
conditions permit.
Bear in mind that at a speed of just 30 mph 
(approximately 50 km/h), your vehicle is 
covering a distance of 44 feet (approximate-
ly 14 m) every second.
