37 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 MANUALhas 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 150.
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 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 pages pages
47–49 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 vehicles equip-
ped 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.
G026489
WARNING
Always refer to the child restraint manufac-
turer's instructions for detailed information
on securing the restraint.

Securing an infant seat with a seat belt
G026417
Do not place the infant seat in the front passeng-
er's seat
NOTE
Refer to pages 47–49 for information on
securing a child restraint using ISOFIX/
LATCH 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 seat
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 vehicles equip-
ped 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 Safety
Booster cushions 01
46
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 the
Passenger airbag off symbol near the rear-
view mirror is illuminated (on vehicles equip-
ped 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.

Trip odometer reset button – The trip
odometers are used to measure short dis-
tances. Press the button briefly to switch
between the odometer for the car's total
mileage and the two trip odometers, T1
and T2. A long press (more than 2 seconds)
resets the currently selected trip odometer.

the temperature of the engine cooling sys-
tem. If the temperature is abnormally high
and the needle enters the red zone, a mes-
sage is shown in the display. Bear in mind
that auxiliary lamps in front of the air intake
reduce the cooling capacity at high outside
temperatures and high engine loads.

washed once for every five times the wind-
shield is washed.
Normal halogen headlights will not be washed.

The rain sensor regulates windshield wiper
speed according to the amount of water on the
windshield. The sensitivity of the rain sensor is
adjusted by moving the thumb wheel (C in the
illustration on the previous page) up (the wipers
will sweep the windshield more frequently) or
down (the wipers will sweep the windshield
less frequently).

The rain sensor should be deactivated when
washing the car in an automatic car wash,
etc. If the rain sensor function is left on, the
wipers will start inadvertently in the car
wash and could be damaged.
Automatic deactivationThe rain sensor is deactivated automatically in
the following situations:
•When the key is removed from the ignition.
•Five minutes after the ignition is switched
off if the key is left in the ignition.
– Thumb wheel
The thumb wheel is used to set the wiper inter-
val when intermittent wiping is selected, or the
sensitivity to the amount of rain on the wind-
shield when the rain sensor is selected. Move
the wheel upward or downward to increase/
decrease wiper speed when the intermittent
function is selected, or to increase/decrease

Calibrating the compass
G031045
The earth is divided into 15 magnetic zones.
The compass is initially set for the zone to
which the car was delivered, and should
always be adjusted if the car is driven to a new
magnetic zone. A "
C" will be displayed if cali-
bration becomes necessary.
To calibrate the compass:
1. Stop the car in a large, open area, away
from traffic.
2. Using a pen or similar object, hold the but-
ton (1) depressed for at least 6 sec-
onds. "
