WARNING Risk of accident and injur
y due
to leaving children unattended in the vehi-
cle
If children are les unatt
ended in the vehicle,
they could, in particular:
= open doors, thereby endangering other
persons or road users.
= get out and be struck by oncoming traPc.
= operate vehicle equipment and become
trapped, for example.
In addition, the children could also set the
vehicle in motion by, for example:
= releasing the parking brake.
= changing the transmission position.
= starting the vehicle. 
Never leave children unattended in the
v
ehicle. 
When leaving the vehicle, always take the
k
ey with you and lock the vehicle. 
Keep the vehicle key out of the reach of
c
hildren. Requirements:
= t

he key is in the vehicle and is recognised.
= the brake pedal is not depressed. 192

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
material in the engine compartment or the
exhaust system
Flammable materials may ignite. 
Therefore, check regularly that there are
no Oammable mat

erials 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
s and press button 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 194).
% You can switch oM t
he vehicle while driving. To
do this, press button 1 for about three sec-
onds or press button 1 three times within
three seconds. Be sure to observe the safety
notes concerning this under "Driving tips"
(  page 197).

Starting the vehicle with the key in the stowage
com partment (emergency operation mode)
If the vehicle does not start and the Place the
key in the marked space See Owner's Manual
message appears in the instrument display, you
can start the vehicle in emergency operation
mode. 
Make sure that marked space 2 is em
pty. 
Remove key 1 fr
om the key ring. 
Place key 1 in mar
ked space 2 next to
symbol 3.
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 next to symbol 3
during the entire journey. 
Have key 1 c
hecked at a qualiNed specialist
workshop.
If the vehicle does not start: 
Place key 1 in mar
ked space 2 and leave it
there. 
Depress the brake pedal and start the vehicle
using t

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.

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 1,500 km:
= Drive at varying road speeds and engine
speeds.
= Do not drive at speeds greater than
140 km/h.
= Drive the vehicle in driving mode A
or .
= Shis to the next highest 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
1,500 km.
This also applies when the engine or parts of the
drivetrain have been replaced. Driving and parking
195

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 not reached until the end
of this teach-in process.
= Brake pads, brake discs and tyres that are
either new or have been replaced only achieve
optimum braking eMect and grip aser several
hundred kilometres of driving. Compensate for
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 233). 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 195).
= 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 213). 
Move the steering wheel to the straight-ahead
position. 
Select the sportiest available drive program
B or C(  pag

e 208). 
Deactivating ESP n
( pag
e 236). 
Depress and hold the brake pedal Nr
mly with
your les foot. 
With your right foot, fully depress the acceler-
at

or pedal. 196
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. &
