The front airbag system
G020111
The front airbags supplement the three-point
seat belts. For these airbags to provide the
protection intended, seat belts must be worn
at all times.
The front airbag system includes gas genera-
tors surrounded by the airbags, and decelera-
tion sensors that activate the gas generators,
causing the airbags to be inflated with nitrogen
gas.
G015167
Location of the passenger's side front airbag
As the movement of the seats' occupants com-
presses the airbags, some of the gas is expel-
led at a controlled rate to provide better cush-
ioning. Both seat belt pretensioners also
deploy, minimizing seat belt slack. The entire
process, including inflation and deflation of the
airbags, takes approximately one fifth of a sec-
ond.
The location of the front airbags is indicated by
SRS AIRBAG embossed on the steering wheel
pad and above the glove compartment, and by
decals on both sun visors and on the front and
far right side of the dash.
•The driver's side front airbag is folded and
located in the steering wheel hub.
•The passenger's side front airbag is folded
behind a panel located above the glove
compartment.

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.

Control panel for the optional power seats.
NOTE
Both front seats are equipped with head
restraints that can be adjusted vertically to
suit the height of the passenger. The upper
edge of the head restraint should be at least
on a level with the upper-most point of the
seat occupant's ear (see the section
"Adjusting the front seat head restraints" on
page 107).
WARNING
•Do not adjust the seat while driving.
•Adjust the driver’s seat and seat belt
(see page 18) before driving. The seat
should be adjusted so that the brake
pedal can be depressed fully.
•Position the seat as far rearward as
comfort and control allow.
Folding down the front seat backrests
G014805
The front passenger's seat backrest can be
folded down to provide room for long loads.
1. Move the seat as far back as possible.
2. Adjust the backrest to the upright position.
3. Lift the catches on the rear of the backrest
as shown in the illustration.
4. Without releasing the catches, push the
backrest forward.
5. Move the seat as far forward as possible
so that the head restraint slides under the
glove compartment.
1Also applies to the optional power seat.

107 Adjusting the front seat head restraints
The front seat head restraints are designed so
that they can be adjusted to two different
height positions.
NOTE
•When the vehicle leaves the factory, the
front seat head restraints will be in the
lower position.
•It is advisable to have the head
restraints in the lower position if you
wish to fold down the seat's backrest.
The head restraints should be put in the upper
or lower position according to the height of the
occupant of the seat.
The upper edge of the head restraint should be
at least on a level with the upper-most point of
the seat occupant's ear (see illustration).
To raise or lower a head restraint:
Raising or lowering a head restraint1. Release the head restraint by pressing the
button underneath its left side, at the base
of the support (see the illustration).
2. Move the head restraint until it clicks
(locks) into the upper or lower position.
WARNING
After adjusting the head restraint, be sure
that it is securely locked in the new position
by pressing and/or pulling it.
Removing a head restraintThe front seat head restraints can be removed,
for example, when cleaning the upholstery or if
the front passenger's seat backrest is folded
down to accommodate a long load. To do so:
1. Release the head restraint by pressing the
release button underneath its left side, at
the base of the support.
2. While holding in the release button, press
the locking button at the base of the head
restraint's right support with a screw
driver, etc., and lift the head restraint until
it can be removed completely.

Catch
Folding down the backrest
Location of the head restraint in the seat
cushion
To fold down one or both sections:1. Grasp the rear edge of the seat cushion
and pull it forward.
2. Pull the catch on the upper outboard edge
of the backrest upward and forward to
release the backrest lock. A red lock indi-
cator is visible when the backrest is not
locked in the upright position.
3. Fold the backrest down partially and
remove the outboard head restraints.
Press the center head restraint down com-
pletely or remove it.
4. Place the head restraints in the plastic
tubes, which are now accessible on the
under side of the seat cushions.
WARNING
The center rear seat head restraint should
only be in its lowest position when this seat
is NOT occupied. When the center position
is occupied, the head restraint should be
correctly adjusted to the passenger’s
height. The upper edge of the head restraint
should be at least on a level with the upper-
most point of the seat occupant's ear.
NOTE
When folding down the rear seat backrests,
remove the plug in the rear 12-volt socket to
help avoid marks in the upholstery.
WARNING
•The red lock indicator is VISIBLE when
the backrest is NOT locked in position
and hidden when the backrest is cor-
rectly locked in place. When the back-
rest is in the upright position, it must
always be correctly locked in place.
•When the rear seat is folded down, do
not place heavy objects against the
backs of the front seats. This places a
severe strain on the folded down back-
rest of the rear seat. Be sure to secure
cargo.
•Cargo must not be stacked higher than
the top of seat backs. This will reduce
the possibility of luggage, etc. becom-
ing projectiles during sudden maneu-
vers, rapid braking or an accident.

165 Loading the vehicle
Your vehicle's load-carrying capacity is affec-
ted by factors such as:
•the number of passengers
•tire inflation
•the amount of optional or accessory equip-
ment installed
•the amount of cargo.
See the chapter "Wheels and tires" for more
detailed information.
Before loading the car, turn off the engine, and
apply the parking brake when loading or
unloading long objects. The gear selector can
be inadvertently knocked out of position by
long cargo, causing the car to move.
Keep the following in mind when
loading the vehicle:
•Load objects in the trunk against the rear
seat backrest.
•Load heavy cargo as low as possible.
•Center wide loads.
•Secure all cargo with restraining straps
anchored to the load securing eyelets.
•Cover sharp edges on the load.
•Seats can be folded down and head
restraints removed to extend the cargo
compartment, see page 115.
WARNING
•Remember that an object weighing
44 lbs (20 kg) produces a force of
2,200 lbs (1,000 kg) in a head-on colli-
sion at 30 mph (50 km/h)!
•When the rear backrest(s) are folded
down, the vehicle should not be loaded
to a level higher than 2 in. (5 cm) below
the upper edge of the rear side win-
dows. Objects placed higher than this
level could impede the function of the
Volvo Inflatable Curtain.
Load carriers (accessory)
Load carriers are available as Volvo accesso-
ries. Follow the installation instructions sup-
plied with the load carriers.
Observe the following points when using load
carriers:
•To avoid damaging your car and to achieve
maximum safety when driving, we recom-
mend using the load carriers that Volvo has
developed especially for your car.
•Volvo-approved removable roof racks are
designed to carry the maximum allowable
roof load for this vehicle: 165 lbs (75 kg).
For Non-Volvo roof racks, check the man-
ufacturer's weight limits for the rack.
•Never exceed the rack manufacturer's
weigh limits and never exceed the maxi-
mum rated roof load of 165 lbs (75 kg).
•Avoid single-point loads. Distribute loads
evenly.
•Place heavier cargo at the bottom of the
load.
•Secure the cargo correctly with appropri-
ate tie-down equipment.
•Check periodically that the load carriers
and load are properly secured.
•Remember that the car's center of gravity
and handling change when you carry a
load on the roof.
•The car's wind resistance and fuel con-
sumption will increase with the size of the
load.
•Drive smoothly. Avoid rapid starts, fast
cornering and hard braking.
