ventilation is no tpossible, toxic exhaust
fumes can ente rthe vehicle, especially car-
bon monoxide. This is th ecase, e.g. in
enclosed spaces, or if th evehicl eiss tuck in
snow. There is ariskoff atal injuries.
You should switch off th eauxiliary heating in
enclosed spaces whic hdonothav eane xtrac-
tion system, e.g. agarage. If th evehicl eis
stuck in snow and you mus tleav ethe auxiliary
heating running, keep th eexhaust pipe and

In certain drivin gand drivin gsafet ysystems,
the sensors adjust automatically while acer-
tain distance is being driven after the vehicle has been delivered or after repairs. Full sys-
tem effectiveness is not reached until the end
of this teach-in process.

new or have been replaced only achieve opti- mum brakin geffec tafter several hundred kil-
ometres of driving. Compensate for the

If you treat the engin ewith sufficient care
from the very start ,you will be rewarded with
excellent performanc efor the remainder of
the engine's life.
R Driv eatv arying road speeds and engine
speeds for the first 1,50 0km.
R Avoid overstraining the vehicle during this
period, e.g. drivin gatfull throttle.
R Change gear in good time, before the rev
counter needle is Ôof the way to the red
area of the rev counter. R
Do not shift down agear manually in order
to brake.
R Vehicles with automatic transmission:
try to avoid depressin gthe accelerator
pedal beyond the point of resistance (kick-
down).
Additional running-in notes for AMG vehicles:
R Do not drive at speeds above 140 km/ hfor
the first 1,500 km.
R Only allow the engine to reach amaximum
engine speed of 4,500 rpm briefly.
After 1,500 km, you may graduall yaccelerate
the vehicle to full road and engine speeds.
i You should also observe these notes on
running-in if the engine or parts of the drive
train on your vehicle have been replaced. AMG vehicles with self-locking rear
axle differential
Your vehicle is equipped with aself-locking
differential on the rear axle.
Change the oil to improve protection of the
rear axle differential:
R after arunning-in period of 3,000 km
R every 50,000 km or 3years
These oil changes prolong the service life of
the differential. Have the oil change carried
out at aqualified specialist workshop. Driving
Important safety notes
G
WARNING
Object sinthe driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardises the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all object ssecurely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always 178
DrivingDriving and parking

sufficient room for the pedals. Do not use
loose floormats and do not place several floor- mats on top of one another. G
WARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is arisk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals. G
WARNING
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 arisk
of an accident.
Do not switch off the ignition while driving. G
WARNING
If the parking brake has not been fully
released when driving, the parking brake can:
R overheat and cause afire
R lose its hold function.
There is arisk of fire and an accident. Release
the parking brake fully before driving off.
! Do not warm up the engine when the vehi-
cle is stationary. Drive off immediately.
Avoid high engine speeds and driving at full throttle until the engine has reached its
operating temperature.
Only shift the automatic transmission to
the desired drive position when the vehicle is stationary.
Where possible,a void spinning the drive
wheels when pulling awayons lippery
roads. You could otherwise damage the
drive train. !
AMG vehicles:
at low engine oil temper-
atures (below +20 †), the maximum
engine speed is restricted in order to pro-
tect the engine. To protect the engine and
maintain smooth engine operation, avoid
driving at full throttle when the engine is
cold.
HYBRID vehicles :make sure that you read
the "HYBRID" Supplement included in the
vehicle literature. Otherwise, you may not
recognise dangers. Key positions

KEYLESS-GO General notes
Vehicles with KEYLESS-GO are equipped with
keys featuring an integrated KEYLESS-GO
function and adetachable Start/Stop button. Driving
179Driving and parking Z

The Start/Stop button must be inserted in the
ignition lock and the key must be in the vehi-
cle.
When you insert the Start/Stop button into
the ignition lock, the system needs approx-
imately two seconds recognition time. You
can then use the Start/Stop button.
Pressing the Start/Stop button several times
in succession corresponds to the different
key positions in the ignition lock. This is only
the case if you are not depressing the brake
pedal.
If you depress the brake pedal and press the
Start/Stop button ,the engine start simmedi-
ately.
Ac heck which periodically establishes aradio
connection between the vehicle and the key
determines whether avalid key is in the vehi-
cle. This occurs, for example, when starting
the engine.
To start the vehicle without actively using the
key:
R the Start/Stop button must be inserted in
the ignition lock
R the key must be in the vehicle
R the vehicle must not be locked with the key
or KEYLESS-GO (Y page 95)
Do not keep the KEYLESS-GO key:
R with electronic devices, e.g. amobile
phone or another key
R with metallic objects, e.g. coins or metal
film
R inside metallic objects, e.g. ametal case
This can affect the functionality of KEYLESS-
GO.
If you lock the vehicle with the key's remote
control or with KEYLESS-GO, after ashort
time:
R you will not be able to switch on the ignition
with the Start/Stop button
R you will not be able to start the engine with
the Start/Stop button until the vehicle is
unlocked again If you lock the vehicle centrally using the but-
ton on the frontd oor (Ypage 101), you can
continue to start the engine with the Start/
Stop button.
The engine can be switched off while the vehi-
cle is in motion by pressing and holding the
Start/Stop button for three seconds. This
function operates independently of the ECO
start/stop automatic engine switch-off func-
tion.
Key positions with KEYLESS-GO :
Start/Stop button
; Ignition lock
When you switch on the ignition ,all of the
indicator lamps in the instrument cluster light up. Further information on situations where
an indicator lamp either fails to go out after
starting the engine or lights up while driving
(Y page 330).
If Start/Stop button :has not yet been
pressed, this corresponds to the key being
removed from the ignition.

Hill start assist Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient .It
holds the vehicle for ashort time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot from the brake pedal to the accelerator pedal and depress it before the vehicle begins to
