WARNINGS + GENERAL SAFETY INFORMATION
WARNING
DEATH OR SERIOUS INJURY CAN OCCUR
According to accident statistics, children are safer when properly restrained in
the rear seating positions than in the front seating positions. NEVER leave Child
Restraint unsecured in your vehicle even when it is unoccupied. In a crash, it
could become a projectile and injure other vehicle occupants.
NEVER place this Child Restraint on a front seat with an airbag.
DEATH OR SERIOUS INJURY can occur. An airbag can strike a
rear-facing infant restraint with enough force to crack the shell
and seriously injure or kill an infant. The back seat is the safest
place for children 12 and under. Refer to the vehicle owner’s instruction manual
before installing this Child Restraint in a seating position with side airbags.

VEHICLE COMPATIBILITY – Choosing a Vehicle Seating Location
Please read the following information before installing this Child Restraint!
The safest seating position is one that works best
for your specific car seat, family and vehicle. When
determining whether the MESA MAX rear-facing car seat
can be used with lower anchors in the rear center seating
position, it is critical that you refer to your vehicle owner’s
instruction book. If the MESA MAX does not install best in
the rear center seating location, it is recommended to move
to one of the outboard seating positions.
Before installing this child restraint you MUST
determine the method of installation and the best vehicle
seating position for that method. This child restraint can be
installed either using LATCH or the VEHICLE SEAT BELT.
ALWAYS park on a level surface when installing a Child
Restraint.

VEHICLE COMPATIBILITY
LATCH (Lower Anchors and Tethers for Children)
Most vehicles manufactured after September 1,
2002 are equipped with LATCH (Lower
Anchors and Tethers for CHildren). Check your
vehicle owner’s instruction book to determine
lower anchor compatible seating positions.
NOTE: No tether is required with this rear-facing
carrier. Only lower anchors are used.
NOTE: In order to use the rear center seating
position with lower anchor, the distance between
the lower anchors may be up to 22” and the
seating position must be approved by the vehicle
manufacturer. If spacing between the lower
anchors is greater than 22” or if the seating
position is not approved by the vehicle
manufacturer then use the vehicle seat belt for
installation.
VEHICLE COMPATIBILITY
Overview of Vehicle Seat Belt Systems
If you do not use lower anchor to
properly secure the child restraint
you must use the VEHICLE SEAT BELT
SYSTEM. Seat belt systems vary by
make, model, and year of your vehicle.
There are some vehicle belts that will
NOT work with this child restraint or
that require additional steps.
CHECK YOUR VEHICLE OWNER’S
INSTRUCTION BOOK
for information regarding your
vehicle seat belt system(s).
This child restraint is compatible with
most vehicle seat belt systems.

BASE INSTALLATION WITH LOWER ANCHORS
We recommend using the load leg to optimize safety of the child in the seat. Load leg should be placed in stowed
position when not in use. If installing without the load leg, bypass step 1 and proceed to step 2.
LEVELING BASE
1 Press the load leg release button on bottom of the
base and pull load leg out from storage. Place on the
vehicle seat with the load leg extended toward the
front of the vehicle cushion.
NOTE: We recommend removing the vehicle floor
mat before installation.
2 Lift the level adjust handle on the top of the base to
extend the foot and change the recline angle. Check
the bubble level angle indicator on either side of
the base. The base is level when the bubble is fully
between the lines. NO partial bubble allowed.
NOTE: If the bubble is not visible, lower the foot to
the lowest position and complete installation. Upon
completion, the bubble should fall between the two
lines.
NOTE: Vehicle must be parked on a level surface to
properly level the base.
If proper angle cannot be achieved with level
adjustable foot, a rolled towel may be used.
Foot must be in fully extended position.
BASE INSTALLATION WITH LOWER ANCHORS
1 Locate the lower anchor connectors on either side of the base and remove
by pushing the corresponding orange button while pulling the connector out
of the lower anchor storage pocket.
2 Attach the lower anchor connectors to the vehicle lower anchors located
in the vehicle seat bight (crease of seat).
NOTE: Check lower anchor connectors are in the upright position.
3 Apply pressure firmly into the base allowing excess lower anchor connector
webbing to retract and tighten.
NOTE: A rocking motion may be necessary to retract excess lower anchor
connector webbing.
NOTE: Anti-Rebound+ Panel must make full contact with the seat back.
If it does not make full contact, please refer to the Waterfall note (pg 27).
Installation is complete when
tightness indicator turns from RED
to GREEN and stays green when
downward push is discontinued.

INSTALLING LOAD LEG
1 After the base is secured, rotate load leg
extension until its showing fully green.
2 Using two hands, separate the two ends to
remove any RED showing.
NOTE: After installing the load leg, check
the level angle indicator on base to ensure
the bubble is still within the lines.
REVIEW SAFETY CHECK ON PAGE 28.
All steps must be achieved.
WHAT IS A WATERFALL?
Many late model vehicles have what industry professionals call a waterfall.
A waterfall is the wedge of material where your vehicle seat cushion and seat
back meet. In some cases, this may prevent the Anti-Rebound+ Panel from
making full contact with the vehicle seat back.
This is an easy issue to resolve by following the steps below:
1 Uninstall your MESA MAX base.
2 Adjust the level adjustment foot to achieve proper recline level.
3 Push the base into the seat back. If there is a gap between the top of the MESA
MAX base and the back of the vehicle seat, place a rolled hand towel in the gap
flush with the top of the base.
4 Proceed to BASE INSTALLATION WITH LOWER ANCHORS (pg 24).
Follow Safety Check (pg 28) to confirm proper installation.

BASE INSTALLATION WITH LOWER ANCHORS – Safety Check
Base doesn’t move more than 1" side-to-side and front-to-back at the belt path.
Lower anchor connector webbing is secure and untwisted.
Ensure tightness indicator is GREEN after each use. If it is not, apply pressure
by pushing base into seat bight (crease of seat) to tighten.
Recline angle is correct. Check the level angle indicator on base to ensure
the bubble is still within the lines. NO partial bubble allowed.
Make sure the load leg is secured and contacts the vehicle floor. Check that the
load leg angle indicator is GREEN. Any RED showing indicates that the load leg
is not properly level with the vehicle floor. Always store the load leg under base
when not in use.
ALL STEPS MUST BE COMPLETE.
If not, return to pg 24 and start over.
