Important safety notes
G
WARNING
If children are left unsupervised in the vehicle, they could:
R open the doors, thus endangering other
people or road users.
R get out and disrupt traffic.
R operate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
R release the parking brake.
R shifting the automatic transmission out of
park position P
R Start the engine.
There is a risk 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. G
WARNING
If you attach heavy or large objects to the
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 objects to the
SmartKey. Remove any bulky key rings before
inserting the SmartKey into the ignition lock.
! Keep the SmartKey away from strong mag-
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: R with electronic devices, e.g. a mobile phone
or another SmartKey
R with metallic objects, e.g. coins or metal foil
R inside metallic objects, e.g. a metal case
This can affect the functionality of the Smart-
Key. Vehicles with KEYLESS-GO start function:
do
not keep the SmartKey in the trunk. Otherwise, the SmartKey may not be detected, e.g. when
starting the engine using the Start/Stop button.
A brief radio connection between the vehicle
and the SmartKey determines whether a valid
SmartKey is in, or in the direct vicinity of, the
vehicle.
This occurs, for example:
R when starting the engine
R while driving
R when using the trunk lid unlocking sensor
R when the external door handles are touched
R during convenience closing SmartKey functions

Soft top (Roadster)
Important safety notes
G
WARNING
If you do not fully open/close the soft top, the soft-top hydraulics depressurize after a short
time. This causes the soft top to lower unex-
pectedly and may cause you or others to be
trapped. There is a risk of injury.
Always open or close the soft top completely.
! Never sit on the soft top or store heavy
objects on it. You will otherwise damage the
vehicle soft top and soft-top covers.
! When opening and closing the soft top,
make sure that:
R there is sufficient clearance above it, as the
soft top swings upwards
R there are no objects on the soft top or the
soft-top covers to the side
R the fabric is not dirty, wet or frozen
R the outside temperature is above -10 †
You could otherwise damage the soft top as
well as other parts of the vehicle.
Take the height of the vehicle into account when
opening and closing the soft top (Y page 293).
Make sure that the soft top is dry and clean
before opening or closing it. Otherwise, water or
dirt could enter the vehicle interior or trunk.
You can open or close the soft top:
R when the vehicle is stationary or
R when you do not exceed a speed of 31 mph
(50 km/h) (Max. 37 mph (60 km/h), to avoid
interrupting the closing process while slightly exceeding this speed)
If there is a strong head wind, it may not be pos- sible to close the soft top fully. In order to close
the soft top fully, reduce your speed or stop the
vehicle in accordance with the traffic condi-
tions.
For safety reasons, Mercedes-Benz recom-
mends that you only open or close the soft top
when the vehicle is stationary.
If the soft top does not open or close fully, the
soft-top hydraulics are depressurized and the
soft top is lowered: R

tion is switched on
R after about
20 seconds if the ignition is switched off Opening/closing with the soft top
