SmartKey
Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake.
Rshifting the automatic transmission out of
park position P
RStart the engine.
There is arisk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
GWARNING
If you attach heavy or large object stothe
SmartKey, the SmartKey could be uninten-
tionally turned in the ignition lock. This could
cause the engine to be switched off. There is a risk of an accident.
Do not attach any heavy or large object stothe
SmartKey. Remove any bulky key rings before
insertingt he SmartKey into the ignition lock.
!Keep the SmartKey away from stron gmag-
netic fields. Otherwise, the remote control
function could be affected.
Strong magnetic fields can occur in the vicin-
ity of powerful electrical installations.
Do not keep the SmartKey:
Rwith electronic devices, e.g. amobile phone
or another SmartKey.
Rwith metallic objects, e.g. coins or metal foil.
Rinside metallic objects, e.g. ametal case.
This can affect the functionality of the Smart- Key. Vehicles with KEYLESS-GO startf
unction:do
not keep the SmartKey on the parcel shelf or in
the trunk.O therwise, the SmartKey may not be
detected, e.g. when startin gthe engine using
the Start/Stop button.
Ac heck which periodically establishes aradio
connection between the vehicle and the Smart-
Key determines whether avalid SmartKey is in
the vehicle. This occurs, for example:
Rwhen startin gthe engine
Rwhile driving
Rwhen the external door handles are touched

GWARNING
If you switch off the ignitio nwhile driving,
safety-relevant functions are only available
with limitations, or not at all .This coul daffect,
for example, the power steering and the brake
boosting effect. You wil lrequire considerably
more effort to steer and brake. There is arisk
of an accident.
Do not switch off the ignitio nwhile driving.
GWARNING
If the parking brake has not been fully
released when driving, the parking brake can:
Roverheat and caus eafire
Rlose its hold function.
There is arisk of fire and an accident. Release
the parking brake full ybefore driving off.
!Do not war mupthe engine with the vehicle
stationary. Drive off immediately. Avoid high
engine speeds and driving at full throttle until
the engine has reache dits operating temper-
ature.
Only shift the automatic transmission to the
desired drive position when the vehicleiss ta-
tionary.
Where possible,a voids pinning the drive
wheels when pulling awa yonslippery roads.
You coul dotherwise damage the drive train.
!Mercedes-AMG vehicles: at low engine oil
temperatures below 68 ‡(+20 †), the max-
imum engine speedisr estricted in order to

General notes
When you insert the Start/Stop button into the
ignitio nlock, the system needs approximately
two seconds recognitio ntime. You can then use
the Start/Stop button.
Pressing the Start/Stop button severalt imes in
succession corresponds to the different key
positions in the ignitio nlock. This is only the
case if you are not depressing the brake pedal.
If you depress the brake pedala nd press the
Start/Stop button, the engine starts immedi-
ately.
