WARNING
•Never use a seat belt for more than one
occupant.
•Never wear the shoulder portion of the
belt under the arm, behind the back or
otherwise out of position. Such use
could cause injury in the event of an
accident.
•Seat belts lose much of their strength
when exposed to violent stretching and
should be replaced after any collision,
even if they appear to be undamaged.
•Never repair the belt yourself; have this
work done by an authorized Volvo serv-
ice technician only.
•Any device used to induce slack into the
shoulder belt portion of the three-point
belt system will have a detrimental
effect on the amount of protection avail-
able to you in the event of a collision.
•The seat back should not be tilted too
far back. The shoulder belt must be taut
in order to function properly.
•Do not use child safety seats or child
booster cushions/backrests in the front
passenger's seat. We also recommend
that children who have outgrown these
devices sit in the rear seat with the seat
belt properly fastened.
Seat belt use during pregnancy
G020105
The seat belt should always be worn during
pregnancy. But it is crucial that it be worn in the
correct way. The diagonal section should wrap
over the shoulder then be routed between the
breasts and to the side of the belly. The lap
section should lay flat over the thighs and as
low as possible under the belly. It must never
be allowed to ride upward. Remove all slack
from the belt and insure that it fits close to the
body without any twists.
As a pregnancy progresses, pregnant drivers
should adjust their seats and steering wheel
such that they can easily maintain control of the
vehicle as they drive (which means they must
be able to easily operate the foot pedals andsteering wheel). Within this context, they
should strive to position the seat with as large
a distance as possible between their belly and
the steering wheel.
Child seatsPlease see page 34 for information on secur-
ing child seats with the seat belts.
Seat belt maintenanceCheck periodically that the seat belts are in
good condition. Use water and a mild deter-
gent for cleaning. Check seat belt mechanism
function as follows: attach the seat belt and pull
rapidly on the strap.

WARNING
•If your vehicle has been involved in a
rear-end collision, the front seat backr-
ests must be inspected by a trained and
qualified Volvo service technician, even
if the seats appear to be undamaged.
Certain components in the WHIPS sys-
tem may need to be replaced.
•Do not attempt to service any compo-
nent in the WHIPS system yourself.
G020125
WARNING
Any contact between the front seat backr-
ests and the folded rear seat could impede
the function of the WHIPS system. If the rear
seat is folded down, the occupied front
seats must be adjusted forward so that they
do not touch the folded rear seat.
G020126
WARNING
•Boxes, suitcases, etc. wedged behind
the front seats could impede the func-
tion of the WHIPS system.
•If the rear seat backrests are folded
down, cargo must be secured to pre-
vent it from sliding forward against the
front seat backrests in the event of a
collision from the rear. This could inter-
fere with the action of the WHIPS sys-
tem.

Child safety01

33 Children should be seated safely
Volvo recommends the proper use of restraint
systems for all occupants including children.
Remember that, regardless of age and size, a
child should always be properly restrained in a
vehicle.
Your vehicle is also equipped with ISOFIX/
LATCH attachments, which make it more con-
venient to install child seats.
Some restraint systems for children are
designed to be secured in the vehicle by lap
belts or the lap portion of a lap-shoulder belt.
Such child restraint systems can help protect
children in vehicles in the event of an accident
only if they are used properly. However, chil-
dren could be endangered in a crash if the child
restraints are not properly secured in the vehi-
cle. Failure to follow the installation instructions
for your child restraint can result in your child
striking the vehicle's interior in a sudden stop.
Holding a child in your arms is NOT a suitable
substitute for a child restraint system. In an
accident, a child held in a person's arms can
be crushed between the vehicle's interior and
an unrestrained person. The child could also be
injured by striking the interior, or by being ejec-
ted from the vehicle during a sudden maneuver
or impact. The same can also happen if the
infant or child rides unrestrained on the seat.
Other occupants should also be properlyrestrained to help reduce the chance of injuring
or increasing the injury of a child.
All states and provinces have legislation gov-
erning how and where children should be car-
ried in a vehicle. Find out the regulations exist-
ing in your state or province. Recent accident
statistics have shown that children are safer in
rear seating positions than front seating posi-
tions when properly restrained. A child restraint
system can help protect a child in a vehicle.
Here's what to look for when selecting a child
restraint system:
•It should have a label certifying that it
meets applicable Federal Motor Vehicle
Safety Standards (FMVSS 213) – or in Can-
ada, CMVSS 213.
•Make sure the child restraint system is
approved for the child's height, weight and
development – the label required by the
standard or regulation, or instructions for
infant restraints, typically provide this infor-
mation.
•In using any child restraint system, we urge
you to carefully look over the instructions
that are provided with the restraint. Be sure
you understand them and can use the
device properly and safely in this vehicle.
A misused child restraint system can result
in increased injuries for both the infant or
child and other occupants in the vehicle.When a child has outgrown the child safety
seat, you should use the rear seat with the
standard seat belt fastened. The best way to
help protect the child here is to place the child
on a cushion so that the seat belt is properly
located on the hips, see page 42. Legislation
in your state or province may mandate the use
of a child seat or cushion in combination with
the seat belt, depending on the child's age and/
or size. Please check local regulations.
A specially designed and tested booster cush-
ion can be obtained from your Volvo retailer.

35 Child restraints
G026491
Infant seat
There are three main types of child restraint
systems: infant seats, convertible seats, and
booster cushions. They are classified accord-
ing to the child's age and size.
The following section provides general infor-
mation on securing a child restraint using a
three-point seat belt. Refer to page 43 and
page 45 for information on securing a child
restraint using ISOFIX lower anchors and/or
top tether anchorages.
G026503
Convertible seat
WARNING
A child seat should never be used in the
front passenger seat of any vehicle with a
front passenger airbag – not even if the
PASSENGER AIRBAG OFF symbol near
the rear-view mirror is illuminated (on vehi-
cles equipped with Occupant Weight Sen-
sor). If the severity of an accident were to
cause the airbag to inflate, this could lead to
serious injury or death to a child seated in
this position.
G026489
Booster cushion
WARNING
Always refer to the child restraint manufac-
turer's instructions for detailed information
on securing the restraint.

WARNING
•When not in use, keep the child restraint
system secured or remove it from the
passenger compartment to help pre-
vent it from injuring passengers in the
event of a sudden stop or collision.
•A small child's head represents a con-
siderable part of its total weight and its
neck is still very weak. Volvo recom-
mends that children up to age 4 travel,
properly restrained, facing rearward. In
addition, Volvo recommends that chil-
dren should ride rearward facing, prop-
erly restrained, as long as possible.

G026417
Do not place the infant seat in the front passeng-
er's seat
NOTE
Refer to page 43 and page 45 for infor-
mation on securing a child restraint using
ISOFIX lower anchors and/or top tether
anchorages.
G026493
Positioning the seat belt through the infant seat
WARNING
•An infant seat must be in the rear-facing
position only.
•The infant seat should not be positioned
behind the driver's seat unless there is
adequate space for safe installation.
1. Place the infant seat in the rear seat of the
vehicle.
2. Attach the seat belt to the infant seat
according to the manufacturer's instruc-
tions.
G026492
Fasten the seat belt
WARNING
A child seat should never be used in the
front passenger seat of any vehicle with a
front passenger airbag – not even if
the "Passenger airbag off" symbol near
the rear-view mirror is illuminated (on vehi-
cles equipped with Occupant Weight Sen-
sor). If the severity of an accident were to
cause the airbag to inflate, this could lead to
serious injury or death to a child seated in
this position.
