CAUTION
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 judg-
ment 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 shift 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 temperatures 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).

CAUTION
When installing a child restraint system
For safety reasons, always install a child restraint 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.

Safety information for children
It is recommended that children sit in the rear seats to avoid acci-
dental contact with the shift lever, wiper switch etc.
Use the rear door child-protector lock or the window lock switch
to avoid children opening the door while driving or operating the

Do not let small children operate equipment which may catch or
pinch body parts, such as the power window, hood, trunk, seats
etc.
Observe the following precautions when children are in the vehi-
cle.
Use a child restraint system appropriate for the child, until the
child becomes large enough to properly wear the vehicle’s seat
belt.
CAUTION
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 shift 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,
