Enables a handsfree operation of thefollowing functions:
● central locking system 3 26
● load compartment 3 35
● ignition switching on and starting the engine 3 131
● anti-theft locking system 3 37
● anti-theft alarm system 3 38
The electronic key simply needs to be on the driver's person.
Note
Always take the electronic key with
you when exiting the vehicle.
The electronic key being left in the
card reader is indicated by a warning
chime 3 104 and a message in the
Driver Information Centre 3 103
when the driver's door is opened.
Additionally, the electronic key
includes the functionality of the
remote control 3 22 and an entry
lighting function 3 114.
For handsfree operation, the
electronic key must be outside the
vehicle, within a range of approx.
one metre of the front doors or load
compartment. The range of operation
for the electronic key buttons can be
restricted by external influences. The
hazard warning flashers confirm
operation.
Handle with care, protect from
moisture and high temperatures and
avoid unnecessary operation.
Note
Do not put the electronic key in the
load compartment during driving, as
this is outside of the detection zone(indicated by a warning chime at low speed 3 104 and a message in the
Driver Information Centre 3 103).
Note
In the event the electronic key is kept
in the front passenger compartment
and a message appears in the Driver
Information Centre (possibly
accompanied by a warning chime)
indicating that it is out of reception
range, we recommend inserting the
electronic key in the card reader.
Note
If the electronic key is not detected
in the front passenger compartment
after opening and closing a door with the engine running, a messageappears in the Driver Information
Centre (accompanied by a warning
chime when a certain speed is
exceeded), indicating that it is out of
reception range.
This helps you avoid, e.g., driving off
after dropping off a passenger who
has the electronic key.
The message disappears when the
electronic key is detected again.
