WARNING
When leaving the vehicle, always remove the
SmartKey from the ignition lock. Always take
the SmartKey with you and lock the vehicle.
Do not leave children unsupervised in the
vehicle, even if they are secured in a child
restraint system, and do not give them access
to an unlocked vehicle. Achild's unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. They could:
R injure themselves on vehicle parts
R be seriously or fatally injured by extreme
heat or cold
R injure themselves or have an accident with
vehicle equipment that may still be in
operation even after the SmartKey has
been removed from the ignition, such as the
seat adjustment, steering wheel
adjustment or memory function.
If children open a door, they could cause
severe or even fatal injury to other persons; if
they get out of the vehicle, they could injure
themselves when doing so or be seriously or
even fatally injured by any passing 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 a child could be burned on these
parts.

WARNING
If a key ring is too heavy or too large, the
weight acting on the SmartKey could cause it
to turn in the ignition lock or catch on the
steering wheel. This could cause the engine
to be switched off suddenly. You could lose
control of the vehicle and cause an accident.
Do not attach any heavy or large key rings to
the SmartKey that is inserted in the ignition.

swhether a valid
SmartKey is in the vehicle by periodically
establishing radio contact.
You can combine the functions of KEYLESS-
GO with those of a conventional key. Unlock
the vehicle by using KEYLESS-GO, for
instance, and lock it using the 000Fbutton on
the SmartKey.
When locking or unlocking with KEYLESS-GO,
the distance between the SmartKey and the

Risk of electric shock G
DANGER
The MAGIC SKY CONTROL electrical system
works at high voltage.
If the cover behind the overhead control unit
is damaged or is removed, electrical
components of MAGIC SKY CONTROL are
exposed. These may be live. If you touch these
components, you may get an electric shock
and could be seriously or even fatally injured.
For this reason, never remove the cover
behind the overhead control unit. Never touch
parts of the electrical system (control unit,
cables or cable connections).
Have all work on MAGIC SKY CONTROL
carried out at a qualified specialist workshop.
The electrical components of MAGIC SKY
CONTROL are protected by a paneling behind
the overhead control panel.
The MAGIC SKY CONTROL control unit is
marked with a yellow warning sticker that
warns you of high voltage. The high-voltage
cables are orange in color. Operating MAGIC SKY CONTROL
