KEYLESS-GO
Important!
For the KEYLESS-GO-system to function properly, the
operator should observe the following:
•The driver should carry the KEYLESS-GO-card with
him / her.
•To avoid radio transmission interference, never store
the KEYLESS-GO-card together with other electronic
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.•If the KEYLESS-GO-card is removed from the vehicle
while the engine is running, or by placing the card
in front of the center armrest (see page 195), the
message “CHIP-CARD – NOT RECOGNIZED!” will
appear repeatedly in the multifunction display,
seepage322.
Find the card or change its present location (e.g.
place it on the front passenger seat or insert it in
shirt pocket).
•If the message “CHIP - CARD – NOT RECOGNIZED”
is ignored for an extended of time (approx.
15 minutes), the engine could stop by itself during a
vehicle stop (e.g. traffic light). The vehicle can then
no longer be centrally locked or the engine
restarted. You must first find the card or change its
present location (e.g. place it on the front passenger
seat or insert it in shirt pocket). Start the engine
again. See page 228.
•Do not forget, the engine can be started by anyone
with a KEYLESS-GO-card that is left inside the
vehicle. Leaving the chip-card behind when exiting
and locking the vehicle, the message “CHIP-CARD –
STILL IN VEHICLE” appears in the multifunction
display, see page 322.
