Opening the trunk
The trunk lid will swing open automatically. You should
always make sure there is sufficient clearance.
A minimum height clearance of 6 ft. (1.85 m) is
required to open the trunk lid.
Press transmit buttonŠ until trunk lid is open.
Important!

locked when the lid is closed if the vehicle is centrally
locked.
Notes:
If the trunk was previously locked separately, it will

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.

cluster displayPractical hints Car care Index •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 198), the
message “CHIP-CARD – NOT RECOGNIZED!” will
appear repeatedly for approx. 2 seconds in the
multifunction display, see page 328.
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. Start the
engine again. See page 230.
•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 328.
•Opening the driver’s door with the engine shut off
and no electronic key in the starter switch, the
message “CHIP-CARD – DO NOT FORGET” appears
as a reminder, see page 328. Important!
In the case of a malfunction in the KEYLESS-GO-system,
we recommend that you carry the electronic key plus
mechanical key with you and keep them in a safe place
so that they are always handy. Never leave the electronic
key in the vehicle.
Notes:
The KEYLESS-GO-function also permits closing of
windows and sliding / pop-up roof (convenience feature),
see page 44.
With the KEYLESS-GO-card in close proximity (approx.
3 ft. [1 m]) of the vehicle, aiming a jet of water at a door
handle (e.g. when washing the vehicle) or cleaning
snow from a door could lock or unlock the vehicle
inadvertently.
To prevent a possible inadvertent lockout, the trunk lid
will open automatically if a KEYLESS-GO-card is
recognized in the area of the rear shelf or inside the
trunk.
