Controls in detail
Locking and unlocking
ț To lock or unlock the vehicle, the
SmartKey with KEYLESS-GO must be
located outside the vehicle within ap-
proximately 3 ft (1 m) of a door or the
trunk.
ț If the vehicle has been parked for more
than 72 hours, you must pull an outside
door handle in order to activate the
KEYLESS-GO function.
ț In order to start the engine with the
SmartKey with KEYLESS-GO:
ț The SmartKey with KEYLESS-GO
must be located in the vehicle.
ț All doors must be closed.
ț The brake pedal must be firmly
depressed. Do not depress the
accelerator.
ț If you have started the engine with the
KEYLESS-GO start/stop button
(
୴ page 41), you can only turn it off
again with this button, even if you have
put the SmartKey in the starter switch
in the meantime.
ț This does not apply if, after starting, the
selector lever is still in position P and
the SmartKey is then inserted in the
starter switch. The SmartKey will then
have priority over the KEYLESS-GO
function and the vehicle’s electrical
system will operate according to the
position of the SmartKey in the starter
switch, even stopping the engine.
ț If the SmartKey with KEYLESS-GO is
positioned farther away from the vehi-
cle, the system may no longer recog-
nize the SmartKey with KEYLESS-GO.
The vehicle then cannot be locked or
the engine started via the KEYLESS-GO
system.
ț If the SmartKey with KEYLESS-GO is re-
moved from the vehicle while the en-
gine is running (e.g. if passenger exits
the vehicle with the SmartKey with
KEYLESS-GO), the message
Key Not
Detected will appear in the multifunc-
tion display while driving off.
Find the SmartKey or change its
present location immediately (e.g.
place it on the passenger seat or insert
it in shirt pocket).
ț Remember that the engine can be
started by anyone with a SmartKey
with KEYLESS-GO that is left inside the
vehicle. If you leave the SmartKey with
KEYLESS-GO behind when exiting and
locking the vehicle, the message
Key
Detected In Vehicle will appear in the
multifunction display.
