7Drive
The automatic transmission changes
gear automatically in the automatic
drive programs (
Ypage 122). All
forward gears are available.
Driving tips
Changing gear
The automatic transmission shifts through the
individual gears automatically when it is in trans-
mission position h. This automatic gear shift-
ing behavior is determined by:
Rthe selected drive program (Ypage 116)
Rthe position of the accelerator pedal
Rthe road speed
Accelerator pedal position
Your style of driving influences how the auto-
matic transmission shifts gear:
Rlittle throttle: early upshifts
Rmore throttle: late upshifts
A dynamic driving style with high longitudinal
and lateral acceleration delays the shift points
to higher engine speeds.
Double-clutch function
When shifting down, the double-clutch function
is active regardless of the currently selected
drive program. The double-clutch function
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:
XIn the automatic drive programs, depress the
accelerator pedal beyond the pressure point.
Depending on the engine speed and the selec-
ted drive program, the automatic transmis-
sion shifts to the lowest gear permissible to
give optimal acceleration.
XEase off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Kickdown is not available in manual mode M.
Rocking the vehicle free
Rocking the vehicle free may help to free the
vehicle if it has become stuck in slush or snow.
To do so, shift back and forth repeatedly
between transmission positionshand k.
The vehicle's transmission management
restricts shifting between transmission posi-
tions hand kto speeds up to a maximum of
5 mph (9 km/h).
To shift back and forth between transmission
positions hand k, move the E-SELECT lever
up and down beyond the pressure point.
Gliding mode

Shifting gears
If you pull on the left-hand or right-hand steering
wheel paddle shifter, the automatic transmis-
sion switches to temporary manual drive pro-
gram for a limited amount of time. Depending on
which steering wheel paddle shifter is pulled,
the automatic transmission immediately shifts
into the next gear down or up, if permitted.
XTo shift up: pull the right-hand steering wheel
paddle shifter (Ypage 121).
The automatic transmission shifts up to the
next gear.
If the maximum engine speed in the currently
engaged gear is reached and you continue to
accelerate, the automatic transmission auto-
matically shifts up in order to prevent engine
damage.
The automatic transmission will not shift up to
the next gear when the engine speed is very
low.
XTo shift down: pull on the left-hand steering
wheel paddle shifter (Ypage 121).
The automatic transmission shifts down to
the next gear.
If the engine were to exceed the maximum
engine speed when shifting down, the auto-
matic transmission protects against engine
damage by not shifting down.
Automatic down shifting occurs when coast-
ing.
When using kickdown, the automatic trans-
mission automatically shifts to a lower gear.
Deactivating
If you have activated temporary manual drive
program, 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 of lateral acceleration, during overrun
mode or when driving on steep terrain.
When temporary manual drive program is deac-
tivated, the automatic transmission shifts into
the automatic drive program that was last selec-
ted. You can also deactivate temporary manual drive
program yourself:
XPull on the right-hand steering wheel paddle
shifter and hold it in place (Ypage 121).
or
XUse the DYNAMIC SELECT controller to
change the drive program (Ypage 116).
Temporary manual drive program is deactiva-
ted. The automatic transmission switches
into the automatic drive program that was last
selected.
Manual mode
General notes
In manual mode M, you can permanently change
gear yourself by using the steering wheel paddle
shifters. The transmission must be in position
h to do this.
The switching times correspond to the previ-
ously active automatic drive program.
The transmission only shifts down automatically at low engine speeds depending on the respec-
tive gear.
In addition to manual mode M, you can also
activate temporary manual drive program
(
Ypage 122).
Activating
In manual mode M, you can change gear your-
self using the steering wheel paddle shifters if
the transmission is in position h. You can see
the currently selected drive program and which gear is engaged in the multifunction display.
XPress the M button (Ypage 121).
M is shown in the multifunction display and
the indicator lamp on the M button lights up.
Shift recommendation
The gearshift recommendations assist you in
adopting an economical driving style. The rec-

ommended gear is shown in the multifunction
display.
XWhen the corresponding gearshift recom-
mendation:appears in the multifunction
display of the instrument cluster, shift to rec-
ommended gear ;.
Display for shift override
If the engine speed becomes too high or too low
as a result of shifting gear, you cannot shift gear
using the steering wheel paddle shifters. If you
then pull the left-hand or right-hand steering
wheel paddle shifter, segments :light up red
briefly.
Downshifting
XPull the left-hand steering wheel paddle
shifter (Ypage 121).
In cases where it is permissible, the automatic transmission shifts down to the next gear.
XMaximum acceleration: pull the left-hand
steering wheel paddle shifter until the trans-
mission selects the optimum gear for the cur-
rent speed.
If you slow down or stop without shifting down,
the automatic transmission automatically shifts down.
Deactivating
XPress the M button (Ypage 121).
The indicator lamp in the button goes out.
RACE drive program (AMG GT C Road-
ster)
The RACE drive program is designed for maxi-
mum performance in terms of shift points and engine speeds. The engine and transmission
should be at normal operating temperature for
the RACE drive program (
Ypage 170). Use the
RACE drive program on a closed-off race circuit.
The RACE drive program is characterized by the
following:
Rthe vehicle exhibits driving characteristics
suitable for the racetrack.
Rall vehicle systems are set for maximum
sportiness.
Rfor optimum performance, the transmission
shifts up later and shifts down sooner.
Rthe multifunction display shows the manual
gearshift program without upshift indicator
(
Ypage 122).
Rthe gearshift recommendation gives you
information for slowly warming up the drive
assemblies and for adopting a fuel-efficient
driving style (
Ypage 123). You can follow the
gearshift recommendations at all times and
shift gear accordingly using the steering
wheel paddle shifters. On the basis of the
gearshift recommendation, using the steering
wheel paddle shifters, you can optimize the
drive train and engine operating mode at any
time.
Rif you have selected a gear manually, this will be maintained until the vehicle speed increa-
ses or decreases dramatically.
Rif you do not follow the gearshift recommen-
dations, the automatic shift points may resultin high fuel consumption.
Rthe suspension exhibits particularly hard
springing and damping settings.
Rthe transmission shift and response times are
significantly shorter with more aggressive
gear changes. This is particularly the case
when shifting up. The shift strategy is thus
designed to interact dynamically with the
high-revving engine.
Rgliding mode is not available.
Rthe ECO start/stop function is not available.

Driving and parking

Observe the following rules when driving on salt-
treated roads:
RIn order to prevent any salt build-up, apply the
brakes occasionally while paying attention to
the traffic conditions.
RCarefully depress the brake pedal and the
beginning and end of a journey.
RMaintain a greater distance to the vehicle
ahead.
Servicing the brakes
!The brake fluid level may be too low, if:
Rif the red brake warning lamp lights up in
the instrument cluster and
Ryou hear a warning tone while the engine is
running
Observe additional warning messages in the
multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked immediately. Consult a qualified specialist workshop to
arrange this.
All checks and maintenance work on the brake
system must be carried out at a qualified spe-
cialist workshop.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop.
If the brake system has only been subject to
moderate loads, you should test the functional-
ity of your brakes at regular intervals.
Information on BAS (Brake Assist) (
Ypage 59).
For safety reasons, Mercedes-Benz recom-
mends only installing the following brake disks
and brake pads/linings:
Rbrake disks that have been approved by
Mercedes-Benz
Rbrake pads/linings that have been approved
by Mercedes-Benz or that are of an equivalent
standard of quality
Other brake disks or brake pads/linings can
compromise the safety of your vehicle.
Always replace all brake disks and brake pads/
linings on an axle at the same time. Always
install new brake pads/linings when replacing
brake disks.
The vehicle is equipped with lightweight brake
disks to which the wheel assembly with rim and
threaded connection is matched. The use of brake disks other than those
approved by Mercedes-Benz can change the
track width and is subject to approval, if appli-
cable.
Shock-type loads when handling the brake
discs, such as when changing wheels, can lead
to a reduction in comfort when driving with light-
weight brake discs. Avoid shock-type loads on
the lightweight brake disks, particularly on the
brake plate.
Mercedes-Benz recommends that you only use
brake fluid that has been specially approved for
your vehicle by Mercedes-Benz, or which corre-
sponds to an equivalent quality standard. Brake
fluid which has not been approved for
Mercedes-Benz vehicles or which is not of an
equivalent quality could affect your vehicle's
operating safety.
AMG high-performance and ceramic
brakes
The AMG brake systems are designed for heavy
loads. This may lead to noise when braking. This
will depend on:
RSpeed
RBraking force
REnvironmental conditions, such as tempera-
ture and humidity
The wear of individual components of the brake
system, such as the brake pads/linings or brake
discs, depends on the individual driving style
and operating conditions.
For this reason, it is impossible to state a mile-
age that will be valid under all circumstances. An aggressive driving style will lead to high wear.
You can obtain more information on this from a
qualified specialist workshop.
New and replaced brake pads and discs only
reach their optimum braking effect after several
hundred kilometers of driving. Compensate for
this by applying greater force to the brake pedal.
Keep this in mind, and adapt your driving and
braking accordingly during this break-in period.
Excessive heavy braking results in correspond-
ingly high brake wear. Observe the brake wear
warning lamp in the instrument cluster and note
any brake status messages in the multifunction
display. Especially for high performance driving,
it is important to maintain and have the brake
system checked regularly.
