Automatic transmission
Downshifting

Briefly press the inside2 of one of the
buttons on the steering wheel.
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 181).
Upshifting

Briefly press the outside1 of one of
the buttons on the steering wheel.
The transmission will shift to the next high-
er gear as permitted by the shift program.
This action simultaneously extends the
gear range of the transmission.Canceling gear range limit

Press and hold the outside1 of one of
the buttons on the steering wheel
until
D reappears in the multifunction
display.
The transmission will shift from the current
gear range directly to gear rangeD.
Shifting into optimal gear range

Press and hold the inside2 of one of
the buttons on the steering wheel.
The transmission will automatically select
the gear range suited for optimal
acceleration and deceleration. This will
involve shifting down one or more gears.
iYou cannot shift with the steering
wheel gearshift buttons 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.

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 multifunction display
(

!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 drive train which
is not covered by the Mercedes-Benz
Limited Warranty.

Activating manual shift program
Press program mode selector
switch1 repeatedly until the
M for
manual program modeM appears in
the multifunction 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.Upshifting

Briefly press the gear selector lever to
the right in theD+direction.
or

Briefly press button1 on the right
side of the steering wheel
(page 186).
The transmission shifts to the next
higher gear.
If, instead of the manual program mode
symbol
M, the psymbol appears in
the multifunction display (
page 177),
shift to the next higher gear. The fuel
supply will otherwise be interrupted to
prevent the engine from overrevving.
iThe manual program modeM will not
be stored. When the engine is turned
off with the manual program modeM
selected, the transmission will go to
the automatic program mode (CorS)
when the engine is restarted.
!In the manual program modeM, the
transmission will not upshift, even if
the engine has reached its overrevving
range. Shift up to the next gear before
the engine has reached its overrevving
range. Make absolutely certain that the
engine speed does not reach the red
marking on the tachometer
(page 24). Otherwise the engine
could be damaged which is not covered
by the Mercedes-Benz Limited
Warranty.

(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 selected.
Stop the vehicle.

Move gear selector lever toP.

Turn off the engine.

Wait at least 10 seconds before
restarting.

Restart the engine.

(for second gear) orR.

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.
iWhen you brake or stop, the transmis-
sion shifts down to a gear from which
you can easily accelerate or take off.

232 Controls in detailDriving systemsSetting the current speed
Accelerate or decelerate to the desired
speed.

Briefly lift or depress the cruise control
lever.
Distronic is activated and the current
speed is set.

Remove your foot from the accelerator
pedal.Setting a higher speed

Briefly tip the cruise control lever in the
direction of arrow1 (
page 231) to
increase vehicle speed in increments
of 5 mph (Canada: 10 km/h).
The new speed is set.
The stored speed is displayed in the
multifunction display for approximately
5 seconds (
page 231), and one or
two segments around the stored speed
come on, on the speedometer
(
page 228).Setting a lower speed

Briefly tip the cruise control lever in the
direction of arrow2 (
page 231) to
decrease vehicle speed in increments
of 5 mph (Canada: 10 km/h).
The new speed is set.
The stored speed is displayed in the
multifunction display for approximately
5 seconds (
page 231), and one or
two segments around the stored speed
come on, on the speedometer
(
page 228).
iIf you do not take your foot off the
accelerator completely, the following
message will appear in the multifunc-
tion display:Distronic override
.
The distance to a slower moving vehi-
cles in front of you will not be set. Your
vehicle speed will then be determined
only by the accelerator pedal position.
iDepressing the accelerator pedal does
not deactivate Distronic. After brief
acceleration (e.g. for passing), the
cruise control will resume the last
speed set.
iWhen you use the cruise control lever
to decelerate, the brakes will be ap-
plied to support deceleration.
In addition, the transmission will
automatically downshift on long down-
hill grades.

Step 9:
Press the “training” button on the ga-
rage door opener motor head unit.
The “training light” is activated.
You have 30 seconds to initiate the follow-
ing two steps.
Step 10:

Return to the vehicle and firmly press,
hold for 2 seconds and release the pro-
grammed signal transmitter button
(2, 3 or4).
Step 11:

Press, hold for 2 seconds and release
same signal transmitter button a sec-
ond time to complete the training pro-
cess.Step 12:

Confirm the garage door operation by
pressing the programmed signal trans-
mitter button (2, 3 or4).
Step 13:

To program the remaining two signal
transmitter 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
integrated signal transmitter to pick up the
signal 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
difficulties programming a gate operator
(regardless of where you live) by using the
programming procedures, replace step 4
with the following:iSome garage door openers (or other
rolling code equipped devices) may
require you to press, hold for 2 seconds
and release the same signal transmit-
ter button a third time to complete the
training process.
