Important safety notes
Do not leave the SmartKey in the trunk. You could otherwise lock yourself out.
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. A child's unsupervised 
access to a vehicle could result in an accident 
and/or serious personal injury. They could:
• injure themselves on vehicle parts
• be seriously or fatally injured by extreme heat or cold
• 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
Do not carry heavy or hard objects in the 
passenger compartment or trunk unless they 
are firmly secured in place.
Unsecured or improperly positioned cargo 
increases a child's risk of injury in the event 
of
• strong braking maneuvers
• sudden changes of direction
• an accident
WARNING
Make sure the trunk lid is closed when the 
engine is running and while driving. Among 
other dangers, deadly carbon monoxide (CO) 
gases may enter the vehicle interior resulting 
in unconsciousness and death.
The trunk lid swings upwards when 
opened. Therefore, make sure that there is 
sufficient clearance above the trunk lid.
To open the trunk lid completely, a minimum 
clearance of 5.90 ft (1.80 m) above the 
ground is necessary.
The trunk lid can be:
• opened and closed manually from outside
• opened automatically from outside
• opened automatically from inside
• locked separately
• unlocked with the mechanical key
• opened with the emergency release button
