RThe way your vehicle is positioned in theparking space after parking is dependent onvarious factors. These include the positionand shape of the vehicles parked in frontand behind it and the conditions of the loca-tion. It may be the case that Active ParkingAssist guides you too far into a parkingspace, or not far enough into it. In somecases, it may also lead you across or onto
the curb. If necessary, cancel the parkingprocedure with Active Parking Assist.
RYou can also preselect transmission position[. The vehicle redirects and does not driveas far into the parking space. Should thetransmission change take place too early,the parking procedure is canceled. A sensi-ble parking position can no longer be ach-ieved from this position.
Exiting a parking space
In order that Active Parking Assist can supportyou when exiting the parking space:
Rthe border of the parking space must behigh enough at the front and the rear. Acurb is too small, for example.
Rthe border of the parking space must not betoo wide. Your vehicle can be maneuveredinto a position at a maximum of 45° to thestarting position in the parking space.
Ra maneuvering distance of at least 3.3 ft(1.0 m) must be available.
Active Parking Assist can only assist you withexiting a parking space if you have parked thevehicle parallel to the direction of travel usingActive Parking Assist.

General notes
With MOExtended tires (tires with run flatcharacteristics), you can continue to drive yourvehicle even if there is a total loss of pressurein one or more tires. The affected tire must notshow any clearly visible damage.
You can recognize an MOExtended tire by theMOExtended marking which appears on thesidewall of the tire. You will find this markingnext to the tire size designation, the load-bear-ing capacity and the speed index(Ypage 307).
MOExtended tires may only be used in con-junction with an active tire pressure monitor.
