WARNING
If children are left unsupervised in the vehicle,
they could:
R open the doors, thus endangering other

R shift the manual transmission into neutral.
R start the engine.
There is a risk of an accident and injury.
When

leaving the vehicle, always take the key

children or animals unattended in the vehicle.
Always keep the key out of reach of children. G
WARNING
If persons (particularly children) are exposed
to heat or cold for a prolonged period, there
is

a risk of serious or even fatal injuries. Never
leave persons (particularly children) unatten-
ded in the vehicle. G
WARNING
If you attach heavy or large objects to the key,
