IMPORTANT:  Make sure to remove bulky or puy 
jackets because they can make the seat belt too loose on 
the child’s body during a crash. In winter, it is safe for the  
child to wear thin, tight-tting sweaters and jackets. 
Have the child sit in the 
booster seat up straight (1) 
and the child must sit all 
the way back (2) so that his 
back touches the backrest 
of the booster. Make sure 
the child is not slouching. 
Slouching is dangerous as 
it puts the lap belt on the 
soft belly.
The red shoulder belt 
guides must always be at 
or up to 1 inch above the 
child’s shoulders (see page 
32).
IMPORTANT:  Stop using this booster in high back 
mode when the red shoulder belt guides can not be 
positioned at or above the child’s shoulders with the 
head rest and back rest in their highest positions. 
HIGHBACK MODE:
