unattended in the vehicle -they could be
injured!
- Exercise caution when adjusting the seat
height. Unsupervised or careless seat ad­
justment can pinch fingers or hands causing injuries.
- While the vehicle is moving, the seat­
backs of the front seats must not be in­
clined too far to the rear because the ef­
fectiveness of the safety belts and the
airbag system is severely compromised -
there is a risk of injury.
- To reduce the risk of injury in the case of
sudden braking or accident, front pas­
sengers must never ride in a moving ve­
hicle with the seatback reclined . Safety
belts and the airbag system only offer
maximum protection when the seatback
is upright and the safety belts are prop­
erly positioned on the body. The more
the seatback is reclined, the greater the
risk of personal injury from an incorrect
seating position and improperly posi­
tioned safety belts .
