Get to Know Your Car Seat
What Seating Location Should I Use?
Review section 2-A to see all of the features of this car seat.
The best seating location for this car seat is one that:
• Is recommended by your vehicle owner’s manual, and
• Results in a secure installation of this car seat.
Some vehicles have specific requirements for where the car seat can be installed, so
be sure to check your vehicle owner’s manual for available seating positions, if any.
For example, sometimes the center rear seat has a lap belt only vehicle seat belt, which
cannot be used when this car seat is in Booster mode.
Review section 7-B, 7-C and 7-D of this manual AND your vehicle owner’s manual.

According to accident statistics, children are safer
when properly restrained in the rear seating positions
than in the front seating positions. The center of the
back seat can be the safest during a possible side
impact.
Which Installation Method Should I Use?
This car seat can be installed in your vehicle using either the vehicle seat belt OR the
lower anchor attachment. Both are equally safe to use. INSTALL USING ONLY ONE
METHOD. Graco allows the securing of the car seat with LATCH system in the booster
mode, only if the vehicle manufacturer allows it. The child still MUST BE SECURED with
the vehicle lap/shoulder seat belt.
Vehicle Seat Belt: Review section 7 and your vehicle owner’s manual to learn how to
install your car seat with the vehicle seat belts.
LATCH or Lower Anchor Attachment: The LATCH system or lower anchor
attachment allows you to securely attach your safety seat in your car without using the
vehicle seat belt and possibly to get a better fit. All 2003 and newer model year vehicles
are required to have a LATCH system, although some manufacturers began including
LATCH earlier. Some vehicle owner manuals use the term ISOFIX to identify the LATCH
system.

LATCH consists of lower anchors and a tether anchor, which are built in to your vehicle,
and a lower anchor attachment and a tether that are built in to your car seat. The lower
anchor attachment is used INSTEAD of the vehicle’s seat belt to secure the child seat
to the vehicle. The tether is used IN ADDITION to the lower anchor attachment OR the
vehicle’s seat belt to secure a forward-facing car seat to the vehicle.
Review your vehicle owner’s manual for exact location and use.

anchors, which are built in to your vehicle, and
lower anchor connectors that are built in your car
seat.
Review section 3-B of this manual AND your vehicle

the vehicle lower anchor spacing is 11 inches
