Rthis equipment must not emit harmful,
electromagnetic radiation.
R this equipment receives electromagnetic
radiation, including radiation which can
trigger unwanted functions.
Any unauthorized change to this equipment
can lead to the user's operating license
being withdrawn.
Important information for using
KEYLESS-GO
R You can use the KEYLESS-GO key as a
conventional key.
R You can combine KEYLESS-GO functions
with those of a conventional key (e.g. open
with KEYLESS-GO and close with the
& button).
R Always carry your KEYLESS-GO key on your
person.
R Never keep the KEYLESS-GO key with:
- electronic equipment, such as your
mobile phone or another key
- metal objects, such as coins or metal foil
This may impair the functioning of KEYLESS-
GO.
R To open or close the vehicle, the KEYLESS-
GO key should be no more than 3 ft (1 m)
from the door or tailgate.
R When the vehicle is parked for more than
72 hours, the KEYLESS-GO function is
deactivated. Pull one of the outer door
handles and turn on the ignition to
reactivate the KEYLESS-GO function.
R If the KEYLESS-GO key is not near the
vehicle, it is possible that the system may
not recognize it. In this case, the vehicle
cannot be locked or started with KEYLESS-
GO.
R If the KEYLESS-GO key has been removed
from the vehicle (e.g. if a passenger leaves
the vehicle with the KEYLESS-GO key):
- while someone is holding the Start/Stop
button or attempting to lock the vehicle
with the outer door handle, the message
Key not detected appears in the
multifunction display
- while the engine is running, the red
message Key not detected appears in
the multifunction display as you pull
away. Find the KEYLESS-GO key or
change its current position immediately
(e.g. place it on the front-passenger seat
or carry it in your shirt pocket.)
R If you have started the engine using the
Start/Stop button, you can turn if off again
by:
- pressing the Start/Stop button again
- inserting the KEYLESS-GO key in the
ignition lock when the vehicle is
stationary and the automatic
transmission is in parking position P.
R You may accidentally unlock the vehicle if
the KEYLESS-GO key is within 3 ft (1 m) of
the vehicle and:
- an outer door handle comes into contact
with water
or
- you are cleaning an outer door handle.
R Note that the engine can be started by any
vehicle occupant if a KEYLESS-GO key is in
the vehicle.
Option 1: there is a KEYLESS-GO key in the
vehicle and a KEYLESS-GO key outside the
vehicle. If you leave the KEYLESS-GO key
behind when you get out and lock the
vehicle, a message does not appear in the
multifunction display.
Option 2: there is a KEYLESS-GO key in the
vehicle but no KEYLESS-GO key outside the
vehicle. When you get out and try to lock
the vehicle, the message Key still in
vehicle appears in the multifunction
display. The vehicle is not locked in this
case.
When starting the engine and while driving,
KEYLESS-GO also checks whether a valid key
is in the vehicle by periodically establishing
radio contact.70SmartKeyOpening and closing

Important safety notes
GWarning!
When leaving the vehicle, always remove the
SmartKey from the starter switch. Always
take the SmartKey with you and lock the
vehicle. Do not leave children unattended in
the vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. A child's unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. The children
could
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
starter switch or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and the child could be burned by these
parts.GWarning!
Do not carry heavy or hard objects in the
passenger compartment or cargo
compartment unless they are firmly secured
in place.
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of
R strong braking maneuvers
R sudden changes of direction
R an accident

Problems with the engineProblemPossible causes/consequences and M SolutionsThe engine does not
start. The starter motor
can be heard.R There is a malfunction in the engine electronics.
R There is a malfunction in the fuel supply.XTurn the SmartKey back to position 0 in the ignition lock before
the next attempt to start with the SmartKey.XBefore the next starting attempt with KEYLESS-GO: shut all open
vehicle doors so that the signals from the SmartKey may be
better received.
or
XPull the Start/Stop button out of the ignition.XUse the SmartKey to start the engine, (Y page 131) as external
radio signals cause KEYLESS-GO to malfunction. Avoid
excessively long and frequent attempts to start the engine as
these will drain the battery.
If the engine does not start after several attempts:
XConsult a qualified specialist workshop.The engine does not
start. You cannot hear
the starter motor.The on-board voltage is too low because the starter battery is too
weak or discharged.XJump-start the vehicle ( Y page 256).
If the engine does not start despite attempts to jump-start it:
XConsult a qualified specialist workshop.The starter motor was exposed to a thermal load that was too high.XAllow the starter motor to cool down for approximately two
minutes.XTry to start the engine again.
If the engine still does not start:
XConsult a qualified specialist workshop.Driving133Driving and parkingBA 204.9 USA, CA Edition A 2011; 1; 6, en-USd2mwentsVersion: 3.0.3.62010-06-15T08:58:39+02:00 - Seite 133Z
