2018 MERCEDES-BENZ AMG GT COUPE wheel

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 116).
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 116).
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 116).
or
XUse the DYNAMIC SELECT controller to
change the drive program (Ypage 111).
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 117).
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 116).
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 116).
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 116).
The indicator lamp in the button goes out.
RACE drive program (AMG GT S and
AMG GT C)
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 165). 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 117).
Rthe gearshift recommendation gives you
information for slowly warming up the drive
assemblies and for adopting a fuel-efficient
driving style (
Ypage 118). 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.

Certain engine systems are designed to keep
the level of poisonous componentsinexhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exact ly inaccordance with the
manufacturer's specific ations.Always have
work on the engine carried out at a qualified
specialist workshop. Mercedes-Benz recom-
men dsthat you use an authorized Mercedes-
Benz Center for th ispurpose. Inparticular, work
relevant to safety or on safety-related systems
must becarried out at a qualified specialist
workshop.
The engine settings must not bechanged under
any circumstances. Furthermore, all specific
service work must becarried out at regular
intervals and inaccordance with the Mercedes-
Benz service requirements.

Brakes
Important safety notes
GWAR NING
If you shift downon aslippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There isan increased danger of skiddin g and
acc iden ts.
Do not shift downforaddit ional engine brak-
ing on a slippery road surface.
Downhill gradients
!On long and steep gradients, you must
reduce the load on the brakes byshifting to a
lower gear ingood time. This allowsyou to
take advantage of the engine's braking effect.
This helps you to avoid overheating the
brakes and wearing them out excessively.
When you take advantage of engine braking, a
driv e wheel may not turn for some time, e.g.
on a slippery road surface. This could cause
damage to the drive train. This type of damage
is not covered bythe Mercedes-Benz war-
ranty.
Heavy and light loads
GWARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
!Depressing the brake pedal constantly
results inexcessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately. Drive
on for a short while. This allowsthe airflow to
cool the brakes more quickly.
Wet roads
If you have driven for a long time inheavy rain
wit hout braking, there may be a delayed reac-
tion from the brakes when braking for the first
time. This may also occur after the vehicle has
been washed or driven through deep water.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle infront.
After driving on a wet road or having the vehicle
washed, brake firmly while paying attention to
the traffic conditions. This willwarm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.
Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt resi-
due may form on the brake discs and brake
pads. This can result in a significantly longer
braking distance.
Driving tips127
Driving and parking
Z

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 58).
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.

Do not use Distance Pilot DISTRONIC:
Rin road and traffic conditions which do not
allow you to maintain a constant speed, for
example in heavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
Rwhen there is poor visibility, e.g. due to fog,
heavy rain or snow
Distance Pilot DISTRONIC may not detect nar-
row vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line.
In particular, the detection of obstacles can be
impaired if:
Rthere is dirt on the sensors or anything else
covering the sensors
Rthere is snow or heavy rain
Rthere is interference by other radar sources
Rthere are strong radar reflections, for exam-
ple, in parking garages
If Distance Pilot DISTRONIC no longer detects a
vehicle in front, it may unexpectedly accelerate
to the speed stored.
This speed may:
Rbe too high if you are driving in a turning lane
or an exit lane
Rbe so high in the right lane that you pass vehi-
cles driving on the left (in countries where
they drive on the right)
Rbe so high in the left lane that you pass vehi-
