2016 MERCEDES-BENZ C CLASS automatic transmission

Hill start assist Hill start assist helps you when pulling away for-
wards or in reverse on an uphill gradient. It holds
the vehicle for a short time after you have
removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and to
depress it before the vehicle begins to roll.
G WARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if: R
you are pulling away on a level road or on a
downhill gradient. R
the transmission is in position N .R
the electric parking brake is applied. R
ESP ®
is malfunctioning.
ECO start/stop function (all vehicles
except PLUG ‑ IN HYBRID)
Introduction This section describes the ECO start/stop func-
tion for all vehicles except PLUG-IN HYBRID
vehicles. Information on the ECO start/stop
function on PLUG-IN HYBRID vehicles
( Y
page 231).
The ECO start/stop function switches the
engine off automatically if the vehicle is stopped
under certain conditions.
The engine starts automatically when the driver
wants to pull away again. The ECO start/stop
function thereby helps you to reduce the fuel
consumption and emissions of your vehicle.
Important safety notes
G WARNING
If the engine is switched off automatically and
you exit the vehicle, the engine is restarted automatically. The vehicle may begin moving.
There is a risk of accident and injury.
If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away.
General notes

ECO start/stop display
The ECO start/stop function is activated when-
ever you start the engine using the SmartKey or
the Start/Stop button.
If the engine has been switched off automati-
cally by the ECO start/stop function, the

The HOLD function can also be activated if the
engine has been switched off automatically. It is
then not necessary to continue applying the
brakes during the automatic stop phase. When
you depress the accelerator pedal, the engine
starts automatically and the braking effect of
the HOLD function is deactivated.
All vehicles (except Mercedes-AMG vehi-
cles): automatic engine switch-off can take
place a maximum of four times in a row (initial
stop, then three subsequent stops).
Mercedes-AMG vehicles: the number of con-
secutive automatic engine switch-offs is unlimi-
ted.

Do not shift the transmission to N
while driving. Otherwise, the auto-
matic transmission could be dam-
aged.
No power is transmitted from the
engine to the drive wheels.
Releasing the brake pedal will allow
you to move the vehicle freely, e.g. to
push it or tow it.
If ESP ®
is deactivated or faulty: shift
the transmission to position N if the
vehicle is in danger of skidding, e.g.
on icy roads.
If you switch the engine off with the
transmission in position R or D , the
automatic transmission shifts to N
automatically.
! Rolling in neutral N can damage
the drive train.

The automatic transmission changes
gear automatically. All forward gears
are available.
Driving tips
Changing gear The automatic transmission shifts to the indi-
vidual gears automatically when it is in trans-
mission position D . This automatic gear shifting
behavior is determined by: R
the selected drive program R
the position of the accelerator pedal R
the road speed
Accelerator pedal position Your style of driving influences how the auto-
matic transmission shifts gear: R
little throttle: early upshifts R
more throttle: late upshifts
Double-clutch function
When shifting down, the double-clutch function
is active regardless of the currently selected
drive program. The double-clutch function158

reduces load change reactions and is conducive
to a sporty driving style. The sound generated 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.
Rocking the vehicle free Rocking the vehicle free by shifting back and
forth between transmission positions D and R
can help to free a vehicle that has become stuck
in mud or snow.
The vehicle's engine management restricts
switching between transmission positions D
and R to speeds up to a maximum of 5 mph
(9 km/h).
To shift back and forth between transmission
positions D and R , move the DIRECT SELECT
lever up and down past the point of resistance.
Gliding mode (Mercedes-AMG vehicles)
Gliding mode is characterized by the following: R
the combustion engine is disconnected from
the drive train. R
the engine speed corresponds to the idling
speed. R
status icon C goes out and status icon C is
displayed in the multifunction display
( Y
page 157).
In drive program C , you can deactivate and acti-
vate gliding mode using the ECO button
( Y
page 151). Gliding mode can be activated under the follow-
ing conditions: R
the speed is within a suitable range. R
the course of the road is suitable, e.g. there
are no steep up or downhill gradients. R
you are no longer depressing the accelerator
pedal.
Gliding mode is deactivated under the following
conditions: R
you depress the accelerator pedal. R
you depress the brake pedal. R
you use the DIRECT SELECT lever to switch
the transmission position ( Y
page 156).R
you switch to drive program RACE
(S ‑ MODEL), S+ or S ( Y
page 154).R
you activate manual gearshifting
( Y
page 161). R
you leave the suitable speed range.
i If you have selected the "Comfort" setting
for the drive (engine management) in drive
program I , you can also activate gliding mode.
You can find information about this in the Dig-
ital Operator's Manual.

Manual gear shifting
General notes You can change gear yourself using the steering
wheel paddle shifters. The transmission must be
in position D .
Depending on which paddle shifter is pulled, the
automatic transmission immediately shifts into
the next gear down or up, if permitted.
Mercedes-AMG vehicles: to use manual shift-
ing, you have two options: R
temporary setting R
permanent setting
If you activate manual gearshifting, the multi-
function display will show the current gear
instead of transmission position D .
If manual gearshifting is deactivated, the gears
will be selected automatically.Automatic transmission 161
