items (e.g. cellular telephones, other KEYLESS-GO-
cards) or metallic objects (e.g. coins, metal foil).
•To lock or unlock the vehicle, the card must be
recognized by the system as being located outside
the vehicle. The card must be in close proximity to a
door or the trunk lid (approx. 3 ft. [1 m]). To activate
the start / stop button function, the KEYLESS-GO-
card must be recognized by the system as being
located inside the vehicle.
•If the KEYLESS-GO-card is positioned farther away
from the vehicle (e.g. inside clothing or a briefcase)
and can no longer be recognized by the system, the
vehicle cannot be locked or the engine started via
the KEYLESS-GO-system.
