Driving after a collision
G026363
If the vehicle has been involved in a collision,
the text
CRASH MODE SEE MANUAL
may
appear in the information display. This indi-
cates that the vehicle's functionality has been
reduced.
This text can only be shown if the display is
undamaged and the vehicle's electrical system
is intact.
CRASH MODE is a feature that is triggered if
one or more of the safety systems (for example,
front or side airbags, an inflatable curtain, or
one or more of the seat belt pretensioners) has
deployed. The collision may have damaged an
important function in the vehicle, such as thefuel lines, sensors for one of the safety sys-
tems, the brake system, etc.
WARNING
•
Never attempt to repair the vehicle
yourself or to reset the electrical system
after the vehicle has displayed
CRASH
MODE SEE MANUAL
. This could
result in injury or improper system func-
tion.
•
Restoring the vehicle to normal operat-
ing mode should only be done by a
trained and qualified Volvo service tech-
nician.
•
After
CRASH MODE SEE MANUAL
has been displayed, if you detect the
odor of fuel vapor, or see any signs of
fuel leakage, do not attempt to start the
vehicle. Leave the vehicle immediately.
Attempting to start the vehicleIf damage to the vehicle is minor and there is
no fuel leakage, you may attempt to start the
vehicle. To do so:
1. Remove the ignition key or optional keyless
drive start control, see page 146.
2. Reinsert the key or start control in the igni-
tion switch. The vehicle will then attempt to
reset CRASH MODE to normal mode.3. Try to start the vehicle.
Moving the vehicleIf the electrical system is able to reset system
status to normal (
CRASH MODE SEE
MANUAL
will no longer be displayed), the
vehicle may be moved carefully from its pres-
ent position, if for example, it is blocking traffic.
It should, however, not be moved farther than
is absolutely necessary.
WARNING
Even if the vehicle appears to be drivable
after CRASH MODE has been set, it should
not be driven or towed (pulled by another
vehicle). There may be concealed damage
that could make it difficult or impossible to
control. The vehicle should be transported
on a flatbed tow truck to a trained and quali-
fied Volvo service technician for inspection/
repairs.

Child restraint systems
0137 Child restraints
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.

Do not place the infant seat in the front passeng-
er's seat
NOTE
Refer to pages 43–45 for information on
securing a child restraint using ISOFIX lower
anchors and/or top tether anchorages.
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.
G026493
Positioning the seat belt through the infant seat2. 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 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.
3. Fasten the seat belt by inserting the latch
plate into the buckle (lock) until a distinct
click is audible.

01 SafetyBooster cushions
0142
Securing a booster cushion
G026489
Position the child correctly on the booster cushion
and 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 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.
Booster cushions are recommended for chil-
dren who have outgrown convertible seats.
1. Place the booster cushion in the rear seat
of the vehicle.
2. With the child properly seated on the
booster cushion, attach the seat belt to or
around the cushion according to the man-
ufacturer's instructions.
3. Fasten the seat belt by inserting the latch
plate into the buckle (lock) until a distinct
click is audible.
4. Ensure that the seat belt is pulled taut and
fits snugly around the child.
WARNING
•
The hip section of the three-point seat
belt must fit snugly across the child's
hips, not across the stomach.
•
The shoulder section of the three-point
seat belt should be positioned across
the chest and shoulder.
•
The shoulder belt must never be placed
behind the child's back or under the
arm.
