Seat belts
01``19
WARNING
•
Never repair the belt yourself; have this
work done by a trained and qualified
Volvo service 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.

securing child seats with the seat belts.Seat belt reminder

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.
G020126
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.
G020125
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.

01 SafetyChild safety
01``35 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
car.
Your car is also equipped with ISOFIX/LATCH
attachments, which make it more convenient
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 cars in the event of an accident only
if they are used properly. However, children
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 car. Find out the regulations existing
in your state or province. Recent accident sta-
tistics have shown that children are safer in rear
seating positions than front seating positions
when properly restrained. A child restraint sys-
tem 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 the illustration on 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 (not available in Canada) can be obtained
from your Volvo retailer for children weighing
33 – 80 lb. (15 – 36 kg) and 38-54 inches
(97 – 137 cm) in height.
WARNING
Do not use child safety seats or child
booster cushions/backrests in the front
passenger's seat. We also recommend that
children under 4 feet 7 inches (140 cm) in
height who have outgrown these devices sit
in the rear seat with the seat belt fastened.

G026491
Infant seatThere 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 pages 43–
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 thePassenger airbag off
symbol near the
rear-view mirror is illuminated (on vehicles
equipped with Occupant Weight Sensor). 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 posi-
tion.
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.

the chest and shoulder.
•
The shoulder belt must never be placed
behind the child's back or under the
arm.

anchors
G015268
ISOFIX lower child restraint anchorsLower anchors for ISOFIX-equipped child
seats are located in the rear, outboard seats,
hidden below the backrest cushions. Symbols
on the seat back upholstery mark the anchor
positions (see the illustration).To access the anchors:1. Put the child restraint in position.
2. Kneel on the child restraint to press down
the seat cushion and locate the anchors by
feel.3. Fasten the attachment on the child
restraint's lower straps to the ISOFIX lower
anchors.
4. Firmly tension the lower child seat straps
according to the manufacturer's instruc-
tions.
NOTE
•
The rear seat's center position is not
equipped with ISOFIX lower anchors.
When installing a child restraint in this
position, attach the restraint's top tether
strap (if it is so equipped) to the top
tether anchorage point (see page 45)
and secure the restraint with the vehi-
cle's center seat belt (see page 37).
•
Always follow your child seat manufac-
turer's installation instructions, and use
both ISOFIX lower anchors and top
tethers whenever possible.
WARNING
•
The ISOFIX lower child restraint
anchors are only intended for use with
child seats positioned in the outboard
seating positions. These anchors are
not certified for use with any child
restraint that is positioned in the center
seating position. When securing a child
restraint in the center seating position,
use only the vehicle's center seat belt.
