Important safety notes

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 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:
• injure themselves on parts of the vehicle
• be seriously or fatally injured through excessive exposure to extreme heat or cold
• injure themselves or cause an accident with vehicle equipment that can be operated even if the SmartKey is removed from the ignition lock 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 on these parts.

WARNING
When adjusting a roller sunblind, the roller blind moves up or down. You might become trapped in the process.
In the event of danger, briefly press the button for the roller sunblind to change the roller blind's direction of movement.
