This vehicle may have rear safety
belt comfort guides. If not, they are
available through your dealer.
The guides may provide added
safety belt comfort for older children
who have outgrown booster seats
and for some adults. When installed
and properly adjusted, the comfort
guide positions the shoulder belt
away from the neck and head.Here is how to install a comfort
guide to the safety belt:
Outboard Positions
1. For the outboard positions, remove the guide from its
storage clip on the interior body.
For the third row center position,
locate the comfort guide
which is located in a storage
pocket, at the top of the seat,
under the headrest on the
driver side of the vehicle. To access the comfort guide,
you will first need to move the
headrest forward by pulling on
the handle behind the seatback.
The comfort guide will now be
accessible.
Third Row Center Position
Pull the comfort guide out of its
storage location and then return
the headrest to its upright

Replacing LATCH System
Parts After a Crash

A crash can damage the LATCH
system in the vehicle. A damaged
LATCH system may not properly
secure the child restraint,
resulting in serious injury or even
death in a crash. To help make
sure the LATCH system is
working properly after a crash,
see your dealer to have the
system inspected and any
necessary replacements made
as soon as possible. If the vehicle has the LATCH system
and it was being used during a
crash, new LATCH system parts
may be needed.
New parts and repairs may be
necessary even if the LATCH
system was not being used at the
time of the crash.
