■General precautions while driving
Driving under the influence: Never drive your vehicle when under the influence of
alcohol or drugs that have impaired your ability to operate your vehicle. Alcohol and
certain drugs delay reaction time, impair judgment and reduce coordination, which
could lead to an accident that could result in death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistakes that other drivers or
pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that distracts the
driver, such as adjusting controls, talking on a cellular phone or reading can result in a
collision with resulting death or serious injury to you, your occupants or others.
■General precaution regarding children’s safety
Never leave children unattended in the vehicle, and never allow children to have or use
the key.
Children may be able to start the vehicle or sh ift the vehicle into neutral. There is also a
danger that children may injure themselves by playing with the windows, the moon
roof, or other features of the vehicle. In addition, heat build-up or extremely cold tem-
peratures inside the vehicle can be fatal to children.
Your vehicle contains batteries and/or accumulators. Do not discard them into the
environment but cooperate with separate collection
(Directive 2006 /66/EC).

■When installing a child restraint system
For safety reasons, always install a child rest raint system in a rear seat. In the event that
the rear seat cannot be used, the front seat can be used as long as the airbag manual
on-off system is set to off.
If the airbag manual on-off system is left on, the strong impact of the airbag deployment
(inflation) may cause serious injury or even death.
■When a child restraint system is not installed on the front passenger seat
Ensure that the airbag manual on-off system is set to on.
If it is left off, the airbag may not deploy in the event of an accident, which may result in
serious injury or even death.
