Notes on breaking-in a new vehicle
Important safety notes
The sensor system of some driving and driving
safety systems adjusts automatically while a
certain distance is being driven after the vehiclehas been delivered or after repairs. Full system
effectiveness is not reached until the end of this
teach-in procedure.
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.
The first 1,000 miles (1,500 km)
The more you look after the engine when it is
new, the more satisfied you will be with its per-
formance in the future.
RYou should therefore drive at varying vehicle
and engine speeds for the first 1,000 miles
(1,500 km).
RIdeally, for the first 1,000 miles (1,500 km),
drive in program C.
RDo not drive faster than 85 mph (140 km/h)
for the first 1,000 miles (1,500 km).
ROnly briefly allow the engine to reach a max-
imum engine speed of 4,500 rpm briefly.
RAvoid heavy loads, e.g. driving at full throttle,
during this period.
RDo not exceed Ôof the maximum permitted
engine speed for each gear.
RShift up into manual mode Mand temporary
manual drive program in good time.
RDo not carry out a RACE START.
RDo not manually shift to a lower gear to brake
the vehicle.
RTry to avoid depressing the accelerator pedal
beyond the pressure point (kickdown).
After 1,000 mile s(1,500 km), you can increase
the engine speed gradually and accelerate the
vehicle to full speed.
You should also observe these notes on break-
ing in if the engine or parts of the drive train on
your vehicle have been replaced.
Always observe the respective maximu m per-
missibl

e speed.
Driving
Important safety notes
GWARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use
loose floormats and do not place floormats on
top of one another.
GWARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
Rshoes with thick soles
Rshoes with high heels
Rslippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals.
GWARNING
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.
GWARNING
If the parking brake has not been fully
released when driving, the parking brake can:
Roverheat and cause a fire
Rlose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.

GWARNING
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:
Ryou are pulling away on a level road or on a
downhill gradient
Rthe transmission is in position i
Rthe electric parking brake is applied
RESP®is malfunctioning
Rear axle steering
General notes
Depending on the speed, rear axle steering
adapts the track of the rear axle to the position
of the front wheels. Together with the steering
angle of the front wheels, this results in greater
mobility and stability than on vehicles without
rear axle steering.
Rear axle steering has the following character-
istics:
Rreduced steering effort and turning circle,
resulting in reduced parking effort.
Rimproved driving stability, e.g. on curves.
Rthe vehicle has more direct steering. Control
of the vehicle is thereby increased.
ECO start/stop function
Introduction
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
GWARNING
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
If the engine has been switched off automati-
cally by the ECO start/stop function, the è
ECO symbol is shown in the multifunction dis-
play.
The ECO start/stop function is only available in drive program C.
The ECO start/stop function is activated when-
ever you switch on the engine using the Smart-
Key or the Start/Stop button. This is the case if:
Rthe ignition was switched off for more than
four hours or
Rthe ECO start/stop function had been activa-
ted before the engine was switched off
Automatic engine switch-off
The ECO start/stop function switches the
engine off automatically if:
Rthe ECO start/stop function is activated
(Ypage 114) and
Ryou brake the vehicle to a standstill in trans-
mission position h

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-

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.

GWAR NING
If you switch off the ignition while driving,
safety-relevant functions are only available
wit hlimit ations, or not at all.This could affect,
for example, the power steering and the brake
boosting effect. You willrequire cons iderably
more effort to steer and brake. There isa risk
of an acc ident.
Do not switch off the ignition while driving.
GWARNING
If you operate mob ilecommunication equip-
ment when driving, you may be distracted
from the traff icsituation. You could also lose
control of the veh icle. There isa risk of an
acc iden t.
Only operate th is equipment when the veh icle
is stationary.
Observe the legal requirements for the country
in whic h you are driving. Some jur isdictions pro-
hibit thedriver from using a mob ilephone while
driv ing a vehicle. If you make a call while driving, always use
hands-free mode. Only
operate the telephone
when the traff icsituation permits. Ifyou are
unsure, pull over to a safe location and stop
before operating the telephone.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers a
distance of 44 ft (approximately 14 m)per sec-
ond.
Drive sensibly – save fuel
Observe the following tips to save fuel:
XThe tires should always be inflated to the rec-
ommended tire pressure.
XRemove unnecessary loads.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all service and maintenance work car-
ried out at the specified intervals.
Fuel consumption also increases when driving in
cold weather, in stop-start traffic and in hilly ter-
rain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
