To install the tether anchor:
1. Route the Child Restraint System
top-tether strap over the seatback.
Route the tether strap under the
head restraint and between the head
restraint posts, or route the tether
strap over the top of the vehicle
seatback. Make sure the strap is not
twisted.
2. Connect the tether strap hook to
the tether anchor, then tighten the
top-tether strap according to the
instructions of your Child Restraint
System’s manufacturer to firmly
attach the Child Restraint System to
the seat.
3. Check that the Child Restraint System
is securely attached to the seat by

WARNING
Take the following precautions when
installing the top-tether:
• Read and follow all installation
instructions provided with your Child

• NEVER attach more than one
Child Restraint System to a single
tether anchor. This could cause the
anchorage or attachment to come
loose or break.
• Do not attach the tether strap to
anything other than the correct
top-tether anchor. It may not work
properly if attached to something
else.
• Child Restraint System anchors are
designed to withstand only those
loads imposed by correctly fitted
Child Restraint System.
Under no circumstances are the
anchors to be used for adult seat
belts or harnesses or for attaching
other items or equipment to the
vehicle.

Securing a Child Restraint System
with a lap/shoulder belt
WARNING
ALWAYS place a rearward-facing Child
Restraint System in the rear seat of the
vehicle.
Placing a rearward-facing child restraint
in the front seat can result in serious
injury or death if the Child Restraint
System is struck by an inflating air bag.
When not using the LATCH system, all
Child Restraint Systems must be secured
to a rear seat with the lap part of a lap/
shoulder belt.
OHI038145
Automatic locking mode
Since all passenger seat belts move
freely under normal conditions and
only lock under extreme or emergency
conditions (emergency locking mode),
you must manually pull the seat belt all
the way out to shift the retractor to the
"Automatic Locking" mode to secure a
Child Restraint System.
The "Automatic Locking" mode will help
prevent the normal movement of the
child in the vehicle from causing the
seat belt to loosen and compromise
the Child Restraint System. To secure a
Child Restraint System, use the following
procedure.
To install a Child Restraint System on the
rear seats, do the following:
1. Place the Child Restraint System on a
rear seat and route the lap/shoulder
belt around or through the Child
Restraint System, following the Child
Restraint System manufacturer’s
instructions. Make sure the seat belt
webbing is not twisted.
Information
When using the rear center seat belt, you
should also refer to the "Rear Seat Belt –
Passenger's 3-point system" section in this
chapter.

Curtain air bags
ONX4030040

Curtain air bags are located along both
sides of the roof rails above the front and
rear doors.
They are designed to help protect the
heads of the front seat occupants and
the rear outboard seat occupants in
certain side impact collisions.
The curtain air bags are designed to
deploy during certain side impact
collisions, depending on the crash
severity, angle, speed and impact.For vehicles equipped with a rollover
sensor the side and/or curtain air bags
and pre-tensioners on both sides of
the vehicle may deploy if a rollover or
possible rollover is detected.
The curtain air bags are not designed
to deploy in all side impact or rollover
situations.
WARNING
To reduce the risk of serious injury or
death from an inflating curtain air bag,
take the following precautions:
•
All seat occupants must wear
seat belts at all times to help keep
occupants positioned properly.
• Properly secure Child Restraint
System as far away from the door as
possible.
• Do not place any objects over the air
bag. Also, do not attach any objects
around the area the air bag inflates
such as the door, side door glass,
front and rear pillar, roof side rail.
• Do not hang other objects except
clothes, especially hard or breakable
objects.
In an accident, it may cause vehicle
damage or personal injury.
• Do not allow passengers to lean their
heads or bodies onto doors, put their
arms on the doors, stretch their arms
