WARNING
•If your vehicle has been involved in a
rear-end collision, the front seat back-
rests must be inspected by a trained
and qualified Volvo service technician,
even if the seats appear to be undam-
aged. Certain components in the
WHIPS system 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 back-
rests 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.

37 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 47. 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 and backrest can be obtained from your
Volvo retailer.

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 48 and
page 50 for information on securing a child
restraint using ISOFIX/LATCH 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.

mation on securing a child restraint using
ISOFIX/LATCH lower anchors and/or top

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.

3. Fasten the seat belt by inserting the latch
plate into the buckle (lock) until a distinct
click is audible.
G026494
Pull out the shoulder section of the seat belt
4. Pull the shoulder section of the seat belt
out as far as possible to activate the belt's
automatic locking function.
Ensure that the seat is securely in place
NOTE
The locking retractor will automatically
release when the seat belt is unbuckled and
allowed to retract fully.
5. Press the infant seat firmly in place, let the
seat belt retract and pull it taut. A sound
from the seat belt retractor's automatic
locking function will be audible at this time
and is normal. The seat belt should now be
locked in place.
6. Push and pull the infant seat along the seat
belt path to ensure that it is held securely
in place by the seat belt.
WARNING
It should not be possible to move the child
restraint (child seat) more than 1 in. (2.5 cm)
in any direction along the seat belt path.
The infant seat can be removed by unbuckling
the seat belt and letting it retract completely.
