Rear-Facing
When installed in the rear-facing position, 

the child seat should be reclined at least 

30˚ from vertical for children and up to 45˚ 

from vertical for infants unable to maintain 

head and neck control (not to exceed 45˚) 

when the car is parked on a level surface. 

When installing the seat in rear-facing mode, 

recline the seat to position 3 and use the 

guide line on the child seat to help achieve 

an acceptable recline angle for rear-facing 

installations.

  

Forward-Facing
IMPORTANT: In forward-facing installations, it is important that the 

base of the child seat rests completely flat on the vehicle seat. As 

illustrated below, it is permissible to allow up to 20% or 3 inches 

(7.6 cm) of the base to hang over the edge of the vehicle seat. 

Some vehicle seats do not allow enough of the child seat base to 

contact the vehicle seat. If this is the case, adjust the recline angle 

to a more upright position. Not doing so could cause the child seat 

not to perform as intended.
