Preparing the vehicle
Your vehicle may be equipped with a "Minispare" emergency spare wheel or MOExtended tires (tires with run-flat properties).
Vehicle preparation is not necessary on vehicles with MOExtended tires.
Vehicles equipped with MOExtended tires are not equipped with a TIREFIT kit at the factory. It is therefore recommended that you additionally equip your vehicle with a TIREFIT kit if you mount tires that do not feature run-flat properties, e.g. winter tires.
A TIREFIT kit can be obtained from an authorized Mercedes-Benz Center.
► Make sure that highway level is
selected.
► Stop the vehicle as far away as possible
from traffic on solid, non-slippery and level
ground.
► Switch on the hazard warning lamps.
► Firmly depress the parking brake.
► Bring the front wheels into the
straightahead
position.
► Move the DIRECT SELECT lever to P.
► Switch off the engine.
► Vehicles without KEYLESS-GO: remove
the SmartKey from the ignition lock.
► Vehicles with KEYLESS-GO: open the
driver's door.
The on-board electronics have status 0, which is the same as the SmartKey having been removed.
► Vehicles with KEYLESS-GO: remove the
Start/Stop button from the ignition lock.
► All occupants must get out of the vehicle.
Make sure that they are not endangered as they do so.
► Make sure that no one is near the danger area while a wheel is being changed.
Anyone who is not directly assisting in the wheel change should, for example, stand behind the barrier.
► Get out of the vehicle. Pay attention to
traffic conditions when doing so.
► Close the driver's door
Only operate the tire inflation compressor using the socket in the footwell of the second row of seats, even if the ignition is turned off.
An emergency cut-off ensures that the onboard electrical system voltage does not drop too low. If the on-board electrical system voltage is too low, power to the sockets is automatically cut off. This ensures that there is sufficient power to start the engine.
