WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbit ein
the immediate vicinity of the air vents. There
is ar isk of injury.
Make sure that all vehicle occupants always
maintain asufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air ventsi nto the vehicle interior,
please observe the following notes:
R keep the air inlet between the windscreen and
the bonnet free of blockages, such as ice,
snow or leaves
R never cover the ventsorv entilation grilles in
the vehicle interior Adjusting the air vents

; Side air vent,l eft
= Control for left side air vent
X To open or close: turn thumbwheel=to the

more effor ttosteer and brake. There is arisk
of an accident.
Do not switch off the ignition while driving. G
WARNING
If the parkin gbrake has not been fully
released when driving ,the parkin gbrake can:
R overheat and cause afire
R lose its hold function.
There is arisk of fire and an accident. Release
the parkin gbrake fully before driving off.
! Do not warm up the engin
ewhen the vehicle
is stationary. Driv eoff immediately. Avoid
high engin espeeds and driving at full throttle
until the engin ehas reached its operating
temperature.
Only shift the automatic transmission to the
desired drive position when the vehicle is sta-
tionary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
! Mercedes-AMG vehicles:
at low engineoil
temperatures (below +20 †), the maximum
engin espeed is restricted in order to protect
the engine. To protect the engin eand main-
tain smoot hengin eoperation ,avoid driving at
full throttle when the engin eiscold. Key positions

i If the key does not belong to the vehicle, it
can still be turned in the ignition lock .How-
ever, the ignition will not be switched on. The
engin ecannot be started.
Start/Stop button General notes
When you insert the Start/Stop butto nintot he
ignition lock ,the system needs approximately
two seconds recognition time. You can then use
the Start/Stop button.
Pressin gthe Start/Stop butto nseveral times in
succession corresponds to the differen tkey
position sinthe ignition lock .This is only the
case if you are not depressin gthe brake pedal.
If you depress the brake pedal and press the
Start/Stop button, the engin estart simmedi-
ately.
Ac hec kwhich periodically establishes aradio
connection between the vehicle and the key
determines whether avalid key is in the vehicle.
This occurs, for example, when starting the
engine. Driving

Starting procedureu
sing the Start/
Stop button The Start/Stop button is only available on vehi-
cles with KEYLESS-GO or the KEYLESS-GO start
function.
The Start/Stop button can be used to start the
vehicle manually without insertin gthe key into
the ignition lock. The key must be in the vehicle and the Start/Stop button must be inserted in
the ignition lock. This mode for startingt he
engine operates independently of the ECO
start/stop automatic engine start function.
You can start the engine if avalid key is in the
vehicle. Switch off the engine and always take
the key with you when leaving the vehicle, even
if you only leave it for ashort time. Pay attention
to the important safety notes.
X Depress the brake pedal and keep it
depressed.
X Press the Start/Stop button once
(Y page 145).

WARNING
Vehicles with automatic transmission:
If the engine speed is above the engine idling speed and you then engage transmission
position Dor R,t he vehicle may accelerate
suddenly. There is arisk of an accident.
When engaging transmission position Dor R,
always keep the brake pedal firmly depressed
and do not depress the accelerator pedal at
the same time.
! Vehicles with manualt
ransmission:
change gear in good time and avoid spinning
the wheels. You could otherwise damage the
vehicle.
Depress the accelerator carefully when pulling
away.
The vehicle locks centrally once you have pulled
away.T he locking knobs in the doors drop down. You can open the doors from the inside at any
time.
You can also deactivate the automatic locking
feature; see the Digital Owner's Manual.
Vehicles with automatic transmission: it is
only possible to shift the transmission from posi- tion Pto the desired position if you depress the
brake pedal. If you do not depress the brake
pedal, the DIRECT SELECT lever can still be
moved but the parking lock remains engaged.
i Vehicles with automatic transmission:
upshifts take place at higher engine speeds
after acold start. This helps the catalytic con-
verter to reach its operating temperature
more quickly.
Information on automatically releasing the elec- trical parking brake (Y page 175).
Pulling away with atrailer To ensure that you do not roll backwards when
pulling away on an uphill slope, apply the electric
parking brake.
X Press and hold handle :.
The electric parking brake continues to brake
and prevent the vehicle from rolling back-
wards.
The red !indicator lamp in the instrument
cluster remains lit.
X Depress the accelerator pedal.
X As soon as the vehicle/trailer combination is
held by the driving force of the engine, release lever :.
The electric parking brake is released.
