2018 MERCEDES-BENZ CLA COUPE automatic transmission

Holding the vehicle stationary on uphill
gradients
GWARNING
If the clutch overheats, the electronic man-
agement system is automatically deactivated. This interrupts the power transmission. The
vehiclem ay,for example, roll backwards on
gradients. There is arisk of an accident.
Never hold the vehicles tationary on uphill
gradients by depressing the accelerator.
The clutch may overheat if you hold the vehicle
stationary on uphill gradients by depressing the
accelerator pedal. If the clutch overheats, a
warning tone sounds.

sage in the multifunction display has disap-
peared.

message appears in the multifunction display.
Do not hold the vehicles tationary on uphill gra-
dients by depressing the accelerator pedal.
Instead, only ever hold the vehicles tationary on
uphill gradients by:
Rdepressing the brake pedal
Ractivating the HOLD function
Rengaging the electric parking brake
Kickdown
Use kickdown for maximu macceleration.
XDepress the accelerator pedalb eyond the
pressure point.
The automatic transmission shifts to alower
geard epending on the engine speed.
XEase off the accelerator pedalo nce the
desired speedisr eached.
The automatic transmission shifts back up.
Mercedes-AMG vehicles: it is only possible to
use kickdown in the automatic drive program
and the temporary manua ldrive program M.
When manua ldrive program Mis permanently
activated, kickdown is not possible. For further information on kickdown in manual

Shifting back and forth between transmission
positions hand kcan help to free up the
vehicleifitg ets stuck in mud or snow. The vehi-
cle's engine management system limits the
speedtoam aximumof5m ph (9 km/h) when
shifting back and forth. To shift repeatedly
between transmission positions hand k,
move the DIRECT SELECT leverupa nd down

Manual gear shifting
General notes
You can change gear yourself using the steering wheel paddle shifters. The transmission must be
in position hto do this.
Depending on which steering wheel 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:
Rtemporary setting
Rpermanent setting
If you activate manual gearshifting, the multi-
function display will show the current gear
instead of transmission position h.
If manual gearshifting is deactivated, the gears
will be selected automatically.
Temporar ysetting
XTo activate: shift the DIRECT SELECT lever to
position h.
XPull steering wheel paddle shifter :or;.
Temporary setting will be active for acertain
amount of time. Under certain conditions the
minimum amount of time is extended, e.g. in the case of lateral acceleration, during an overrun
phase or when driving on steep terrain.
XTo deactivate: pull steering wheel paddle
shifter ;and hold it in place.
or
XUse the DIRECT SELECT lever to switch the
transmission position.
or
XAll vehicles (except Mercedes-AMG vehicles):
use the DYNAMI CSELECT button to change
the drive program.
Mercedes-AMG vehicles: use the DYNAMIC
SELECT controller to change the drive pro-
gram.

Shifting gears
!Mercedes-AMG vehicles: the automatic
transmission does not shift up automatically
even when the engine limiting speed for the
current gear is reached. When the engine lim-
iting 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 arisk of engine damage.
XTo shift up: pull steering wheel paddle
shifter ;.
The automatic transmission shifts up to the
next gear. All vehicles (except Mercedes-AMG vehi-
cles):
if the maximum engine speed on the
currently engaged gear is reached and you
continue to accelerate, the automatic trans-
mission automatically shifts up in order to
prevent engine damage.
XTo shift down: pull steering wheel paddle
shifter :.
The automatic transmission shifts down to
the next gear.
Automatic down shifting occurs when coast-
ing.
If the engine exceeds the maximum engine
speed when shifting down, the automatic
transmission protectsa gainst engine damage
by not shifting down.
Shift recommendation
The gearshift recommendations assist you in
adopting an economical driving style. The rec-
ommended gear is shown in the multifunction
display.
XShift to recommended gear ;according to
gearshift recommendation :when shown in
the multifunction display.
Upshifting (Mercedes-AMG vehicles)
!In manual mode, the automatic transmis-
sion does not shift up automatically 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 arisk of engine damage.

Kickdown
XFor maximum acceleration, depress the
accelerator pedal beyond the pressure point.
The automatic transmission shifts to alower
geard epending on the engine speed.
XShift back up once the desire dspeed is
reached. During kickdown, yo
ucannot shift gears using
the steering wheel paddl eshifters.
If yo uapply fullthrottle ,the automatic trans-
missio nshifts up to the next gearw hent he
maximum engine speed is reached.T hispre-
vents the engine from overrevving.
Mercedes-AMG vehicles: it is only possible to
use kickdown in temporary manual drive pro-
gram M.Whenm anual drive program Mis per-
manently activated, kickdown is not possible.

Parking
Important safety notes
GWARNING
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 arisk 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.
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is arisk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
!Always secure the vehicle correctly against
rolling away.O therwise, the vehicle or its driv-
etrain could be damaged.
To ensure that the vehicle is secured against
rolling away unintentionally:
Rthe electric parking brake must be applied.
Rthe transmission must be in position jand
the transmission position display must show
j in the multifunction display.
Rthe SmartKey must be removed from the igni-
tion lock.
Ron uphill or downhill gradients, the front
wheels must be turned towards the curb.
Switching off the engine
Important safety notes
GWARNING
The automatic transmission switches to neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away.T here isarisk of an
accident.
After switching off the engine, always switch
to parking position P.Prevent the parked vehi-
cle from rolling away by applying the parking
brake.
