WARNING!
Long belt path is only for use with a lap-shoulder belt. Never 
use the long belt path option with LATCH or a lap belt.
Use
 only the vehicle’s lap and shoulder belt system when 
restraining a child in booster mode. Never restrain a child with 
only a lap belt in booster mode.
You MUST always
 use the Versa-Tether for children weighing 65 
– 85 lbs (29.5 – 38.6 kg) in harness mode.
Install forward-facing only.
DO NOT use anything to raise the child seat off of the vehicle seat.
Refer to your vehicle owner’s manual or contact the vehicle 
manufacturer for the maximum weight rating for the LATCH 
anchors in your vehicle. Use the vehicle belt (not LATCH 
connectors) for installations with children who weigh more than 
the vehicle LATCH anchor limit. Unless specified otherwise by 
the vehicle manufacturer, assume a 40 lb (18.2 kg) child is the 
vehicle LATCH anchor limit.
General Information
Harness Mode
The positioning block must be 
rotated to the front when installing 
the child seat in harness mode.
Based on your vehicle’s seat belt 
configuration, you may achieve 
a more secure installation using 
one of two approved lap-
shoulder belt path options (long 
or short belt path). If the first 
installation method results in more than 1 in. (2.5 cm) of front-to-
back or side-to-side movement at the belt path, try the other option. 
See page 32 for information on selecting a belt path to install this 
child seat in your vehicle.
Use this child seat in harness mode with children at least 2 years of 
age and 25 – 85 lbs (11.4 – 38.6 kg) who stand 30 – 57 in. (76.2 – 
144.8 cm) in height. Britax recommends using harness mode to 85 
lbs (38.6 kg). See the Child Seat Fit Recommendations section on 
page 8 for information on when your child has outgrown harness mode.
Booster Mode
The positioning block must 
be rotated to the back when 
positioning the child seat in 
booster mode.
This child seat can be used in 
booster mode with children who 
stand 42 – 65 in. (106.7 – 165.1 
cm) in height and weigh more 
than 40 lbs (18.2 kg). Britax 
recommends using harness 
mode to 85 lbs (38.6 kg). 
When positioning this child 
seat in booster mode use the 
vehicle’s lap-shoulder belt to 
secure the child and child seat 
into the desired seating position. 
In booster mode, this child 
seat can be positioned on the 
vehicle seat using LATCH. Use 
the vehicle’s lap-shoulder belt 
to secure the child. Ensure that the LATCH system does not interfere 
with the vehicle belt function and alignment when securing your child.
