2015 MERCEDES-BENZ SLK-Class transmission

Double-clutch function
When shifting down, the double-clutch func-
tion is active regardless of the currently selec-
ted drive program. The double-clutch function reduces load change reactions and is condu-cive to a sporty driving style. The sound gen-
erated by the double-clutch function depends
on the drive program selected.
Kickdown Use kickdown for maximum acceleration.
X Depress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to a
lower gear depending on the engine speed.
X Ease off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up. Program selector button

vehicles).
i AMG vehicles:
when in drive program C
and with a small load demand, the engine
will automatically only operate with four
cylinders. This is the case in city traffic or
on a country road, for example. This
reduces fuel consumption. Cylinder shut-
off is inactive in drive programs Sand M, so
that the engine will operate with all eight
cylinders.

Automatic drive programs E and S Drive program
E(drive program Con MAG
vehicles) is characterized by the following:
R comfort-oriented engine and transmission
settings
R optimal fuel consumption resulting from
the automatic transmission shifting up
sooner
R the vehicle pulling away more gently in
forward and reverse gears, unless the
accelerator pedal is depressed fully R
increased sensitivity. This improves driving
stability on slippery road surfaces, for
example
R the automatic transmission shifting up
sooner. This results in the vehicle being
driven at lower engine speeds and the
wheels being less likely to spin
Drive program Sis characterized by the fol-
lowing:
R sporty engine and transmission settings
R the vehicle pulling away in first gear
R the automatic transmission shifting up
later
R the fuel consumption possibly being higher
as a result of the later automatic transmis- sion shift points
Manual drive program M General notes
In this drive program, you can briefly change
gear yourself by using the steering wheel pad-
dle shifters. The transmission must be in posi- tion D.

selector lever to the left or pull and hold the
left-hand steering wheel paddle shifter until the transmission shifts to the optimal gear
for the current speed.
i If the engine exceeds the maximum
engine speed when shifting down, the auto-
matic transmission protects against engine damage by not shifting down.
i Automatic down shifting occurs when
coasting.
Deactivating
If you have activated manual drive program
M, it will remain active for a certain amount of time. Under certain conditions the minimum
amount of time is extended, e.g. in the case oflateral acceleration, during an overrun phase
or when driving on steep terrain.

vated, the automatic transmission shifts into
the automatic drive program that was last
selected, i.e. Eor S.
You can also deactivate manual drive pro-
gram Myourself:

AMG vehicles !
In manual drive program
M, the automatic
transmission does not shift up automati-
cally even when the engine limiting speed
for the current gear is reached. When the
engine limiting speed is reached, the fuel
supply is cut to prevent the engine from
overrevving. Always make sure that the
engine speed does not reach the red area of
the tachometer. There is otherwise a risk of
engine damage. 0043

WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system or exhaust
gas flow. There is a risk of fire.
Park the vehicle so that no flammable mate-
rials come into contact with parts of the vehi- cle which are hot. Take particular care not to
park on dry grassland or harvested grain
fields. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving. G

R release the parking brake.
R shift the automatic transmission out of park
position Por shift manual transmission into
neutral.
R start the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
