no key in the ignition lock. For this reason,
children should never be left unsupervised in
the vehicle. They could adjust the seats and
become trapped. G
WARNING
Only adjust the driver's seat when the vehicle
is stationary. You will otherwise be distracted
from the road and traffic conditions and you
could lose control of the vehicle as a result of
the seat moving. This could cause an acci-
dent. G
WARNING

when adjusting the seats.
Observe the notes on airbags.
Secure children as recommended; see the
"Children in the vehicle" section. G
