DANGER Risk of f
atal injuries due to
exhaust gases
Combustion engines emit poisonous exhaust
g
ases such as carbon monoxide. Breathing in
these exhaust gases is hazardous to health
and results in poisoning. 
Never leave the engine and, if present,
t

he stationary heater, running in an
enclosed space without suPcient venti-
lation. &
WARNING Risk of Nr
e due to Oammable
materials in the engine compartment or
on the exhaust system
Flammable materials may ignite. 
Therefore, regularly check that there are
no Oammable f

oreign materials in the
engine compartment or on the exhaust
system. Requirements:
= The k

ey is in the vehicle and is recognised. 
Shis t
he transmission to position j or i. 
Depress the brake pedal and press button 1
once. 
If the vehicle does not start: switch oM non-
essential consumer eq
uipment and press but-
ton 1 once. 
If the vehicle still does not start and the Place
the key in the marked space See Owner's
Manual displa

y message appears on the
instrument display: start the vehicle with the
key in the marked space (emergency opera-
tion mode) ( page 154).
% You can switch oM t
he vehicle while driving. To
do this, press and hold button 1 for about
three seconds or press button 1 three times
within three seconds. Be sure to observe the
safety notes concerning this under "Driving
tips" ( page 157).

can start the vehicle in emergency mode. 
Make sure that marked space 2 is em
pty.
Remove key 1 fr
om the key ring.
Place key 1 in s
towage compartment 2.
The vehicle will start aser a short time.
If you remove key 1 from marked space 2,
the vehicle can still be driven. For further
engine starts, however, key 1 must be loca- ted in marked space
2 dur
ing the entire jour-
ney. 
Have key 1 c
hecked at a qualiNed specialist
workshop.
If the vehicle does not start:

qCooling or heating t

he vehicle interior before
starting the journey
Ensure the following before starting the engine:
= The legal stipulations in the area where your
vehicle is parked allow engine starting via
smartphone. =
It is saf
e to start and run the engine where
your vehicle is parked.
= The fuel tank is suPciently full.
= The starter battery is suPciently charged.

qCharging the starter battery before starting the
journey
You can receive a message on your smartphone
when the state of charge of the starter battery is
low. You can then start the vehicle with the smart-
phone to charge the battery. The vehicle is auto-
matically switched oM aser ten minutes.
Ensure the following before starting the engine:
= The legal stipulations in the area where your

WARNING Risk of cr
ushing or entrapment
due to unintentional starting of the engine
Limbs could be crushed or trapped if the
engine is s
tarted unintentionally during service
or maintenance work. 
Always secure the engine against unin-
t

entional starting before carrying out
maintenance or repair work. Requirements:
= P

ark position j is selected.
= The anti-thes alarm system is not activated.
= The hazard warning light system is switched
oM.
= The bonnet is closed.
= The doors are closed and locked.
= The windows and sliding sunroof are closed. 
Start the vehicle using the smartphone.
Aser e

very engine start, the engine runs for
ten minutes. You can carry out a maximum of two consecutive
s
tarting attempts. You must start the engine with
the key before trying to start the vehicle again
with the smartphone.
You can switch oM the vehicle at any time as fol-
lows:
= Via the Smartphone App
= By pressing the Ü or ß button on the
key
% Further information can be found in the
smar
tphone app.
Securing the vehicle against starting before carry-
ing out maint
enance or repair work: 
Switch on the hazard warning light system.
or 
Unlock the doors.
or 
Open a side window or the sliding sunroof. Running-in notes
To preserve the engine during the Nr

st 1500 km:
= Drive at varying road speeds and engine
speeds.
= No faster than 140 km/h.
= Drive the vehicle in drive mode A or .
= Shis to the next higher gear at the very latest
when the needle reaches the last third before
the red area in the rev counter.
= Do not shis down manually in order to brake.
= Avoid overstraining the vehicle, e.g. driving at
full throttle.
= Do not depress the accelerator pedal past the
pressure point (kickdown).
= Only increase the engine speed gradually and
accelerate the vehicle to full speed aser
1500 km.
This also applies when the engine or parts of the
drivetrain have been replaced. Driving and parking
155

Please also observe the following running-in
no
tes:
= In certain driving and driving safety systems,
the sensors adjust automatically while a cer-
tain distance is being driven aser the vehicle
has been delivered or aser repairs. Full sys-
tem eMectiveness is only reached when this
teaching-in process has concluded.
= Brake pads, brake disks and tyres that are
either new or have been replaced only achieve
optimum braking eMect and grip aser driving
several hundred kilometres. Compensate the
reduced braking eMect by applying greater
force to the brake pedal. Notes on optimised acceleration
If all necessary requirements and activation con-
ditions ar

e fulNlled, the best possible acceleration
can be achieved from a standstill.
Do not use the optimised acceleration on public
roads. Individual wheels could spin and you could
lose control of the vehicle. There is an increased
risk of skidding and/or accident. Be sure to observe the safety notes and informa-
tion on ESP
n
( pag

e 184). Pulling away with optimised acceleration
&
WARNING Risk of skidding and ha
ving an
accident from wheels spinning
When you use optimised acceleration, individ-
ual wheels could spin and y
ou could lose con-
trol of the vehicle.
If ESP n
is deactivated, there is a risk of skid-
ding and accident! 
Make sure that no persons or obstacles
ar
e in the close vicinity of your vehicle. Requirements:
= t

he vehicle is run in ( page 155).
= the vehicle and tyres are in good condition.
= you are on a high-grip roadway.
= the engine and transmission are at normal
operating temperature. *
NOTE Incr
eased wear due to optimised
acceleration When pulling away with optimised accelera-
tion, all com

ponents of the drivetrain are sub-
jected to a very high load.
This can lead to increased component wear. 
Do not always pull away with optimised
acceler

ation. 
Engage the h dr
ive position ( page 168). 
Move the steering wheel to the straight-ahead
position. 
Select the sportiest available drive program
B or C(  pag

e 165). 
Deactivating ESP n
( pag
e 186). 
Depress and hold the brake pedal Nr
mly with
your les foot. 
With your right foot, fully depress the acceler-
at

or pedal. 156
Driving and parking


Aser no more than Nve seconds, take your les
foot quickly oM the brake, but keep the accel-
erator pedal depressed.
The vehicle will pull away at maximum acceler-
ation. 
Switch on ESP n
once t
he acceleration proce-
dure is complete.
Ending optimised acceleration 
Remove your foot from the accelerator pedal. 
Reactivate ESP n
.
% Aser y
ou pull away with optimised accelera-
tion, components of the drivetrain can
become very hot, which means that optimised
acceleration values may be reached again
only aser a few minutes. Notes on driving
&
WARNING Risk of accident due t
o objects
in the driver's footwell
Objects in the driver's footwell may impede
pedal tr
avel or block a depressed pedal. This jeopardises the operating and road safety
of t

he vehicle. 
Stow all objects in the vehicle securely
so t
hat they cannot get into the driver's
footwell. 
Always Nt t
he Ooor mats securely and as
prescribed in order to ensure that there
is always suPcient room for the pedals. 
Do not use loose Ooor mats and do no
t
place Ooor mats on top of one another. &
WARNING Risk of accident due t
o incor-
rect footwear
Incorrect footwear includes, for example: = shoes wit

h platform soles
= shoes with high heels
= slippers
There is a risk of an accident. 
Always wear suitable footwear so that
y

ou can operate the pedals safely. &
WARNING Risk of accident if t
he vehicle is
switched oM while driving
If you switch oM t
he vehicle while driving,
safety functions are restricted or no longer
available.
This may aMect the power steering system and
the brake force boosting, for example.
You will need to use considerably more force
to steer and brake, for example. 
Do not switch oM t
he vehicle while driv-
ing. &
DANGER Risk of f
atal injuries due to

g
ases such as carbon monoxide. Breathing in
