Buckling and unbuckling seat belts
Make sure that all passengers have buckledtheir seat belts before starting to drive.
Buckling seat belts
1. Pull out the belt slowly and make sure it isnot twisted or damaged.
If the seat belt in the second row centerseating position is used, make sure it is prop-erly positioned in the correct seat belt guide.

NOTE
Each seat belt is equipped with a retractorthat will lock up in the following situations:
•if the belt is pulled out rapidly
•during braking and acceleration
•if the vehicle is leaning excessively
•when driving in turns
•if the automatic locking retractor/emer-gency locking retractor (ALR/ELR) is acti-vated. Each seat belt (except for the driv-er's) is equipped with an ALR function,which is designed to keep the seat belttaut when installing a child restraint. ALRis activated when the seat belt is pulledout as far as possible. If this is done, asound from the seat belt retractor will beaudible, which is normal. The seat belt cannow only be fed into the retractor, notpulled out. This function is automaticallydisabled when the seat belt is unbuckledand fully retracted.

2.Buckle the seat belt by pushing the latchplate into the receptacle.
> A distinct "click" indicates that the belt islocked into place.

WARNING
Always insert the seat belt latch plate into thebelt buckle on the correct side. Failure to doso could cause the seat belts and belt buck-les to malfunction in a collision. There is a riskof serious injury.
3.The height of the seat belts in the front seatsand outboard rear seating positions can beadjusted.
Press the button on the seat belt holder andmove the belt up or down.
Position the belt as high as possible withoutit chafing against the neck.
The belt should be positioned closely against the insideof the shoulder (against the collarbone, not down overthe arm).
4. Tighten the lap section of the seat belt overthe hips by pulling the diagonal sectionupward toward the shoulder.
The lap section of the seat belt should be positioned lowon the hips (not against the abdomen).

WARNING
Never use a seat belt for more than oneoccupant. Never wear the shoulder portion ofthe belt under the arm, behind the back orotherwise out of position. Such use couldcause injury in the event of an accident. Asseat belts lose much of their strength whenexposed to violent stretching, they should bereplaced after any collision, even if theyappear to be undamaged.

WARNING
Do not use clips or fasten the belts aroundhooks or other parts of the interior. This willprevent the seat belt from fitting properly.

WARNING
Never damage the seat belts and never insertany foreign objects into the belt buckle. Thismay cause the seat belts and belt buckles tomalfunction in a collision. There is a risk ofserious injury.

Unbuckling seat belts
1. Press the red button on the seat belt recep-tacle and make sure the seat belt retractsfully into the retractor slot.
2. If it does not fully retract, guide the belt man-ually into the slot and make sure it does nothang loose.
If the seat belt in the second row centerseating position is used, make sure it is prop-erly positioned in the correct seat belt guide.

Seat belt tensioners
The vehicle is equipped with standard and elec-tric seat belt tensioners that can help tension theseat belt in a critical situation or collision.
Standard seat belt tensioners
All seat belts are equipped with a standard seatbelt tensioner.
In a collision of sufficiently violent force, the seatbelt tensioners will tension the seat belts in orderto more effectively restrain the occupants.

Electric seat belt tensioners
The driver's and front passenger's seat belts areequipped with electric seat belt tensioners.
The seat belt tensioners interact and can be acti-vated in conjunction with the City Safety andRear Collision Warning driver support systems. Incritical situations, such as if the vehicle brakessuddenly, begins to skid or runs off the road (e.gif the vehicle rolls into a ditch, lifts off the groundor hits an obstacle in the road), or if there is a riskof collision, the seat belts can be pulled taut bythe seat belt tensioner's electric motor.
The electric seat belt tensioner helps to positionthe occupant more effectively in the seat, whichreduces the risk of the occupant striking the inte-rior of the passenger compartment and improvesthe effect of other safety systems such as theairbags.

WARNING
If your vehicle has become water-damaged inany way (e.g., soaked floor mats/standingwater on the floor of the vehicle), do notattempt to start the engine. This may causeairbag deployment, which could result in seri-ous injury. Volvo recommends towing thevehicle directly to an authorized Volvo work-shop.
Before attempting to tow the vehicle:
1.Switch off the ignition for at least 10minutes and disconnect the battery.
2. Follow the instructions for manually over-riding the shiftlock system.

Deployed airbags
WARNING
If any of the airbags have deployed:
•Do not attempt to drive the vehicle. Haveit towed to an authorized workshop.
•If necessary, seek medical attention.

Driver/passenger-side airbags
As a supplement to the seat belts, the vehicle isequipped with driver and passenger side frontairbags.
Driver/passenger side front airbags.
In a frontal collision, the airbags help protect thedriver's and passenger's head, face and chestand the driver's knees and legs.
A collision of a sufficiently violent force will trig-ger the sensors and one or more airbags willinflate. The airbag helps cushion the initial impactof the collision for the passenger. The airbagdeflates when compressed by the collision. Asmall amount of powder will also be releasedfrom the airbag. This may appear to be smokeand is normal. The entire process, from inflationto deflation of the airbag, occurs within tenths ofa second.
NOTE
The sensors react differently depending onthe circumstances of the accident andwhether or not the seat belt is used. Does notapply to all belt positions.
In some accident situations, only one (ornone) of the airbags will be deployed. Thesensors monitor the impact of the collisionand react accordingly to deploy one, severalor no airbags.

WARNING
The seat belt and the airbag work together. Ifthe seat belt is not used or is used incorrectly,the airbag may not provide the intended pro-tection in a collision.
To help prevent injury in the event the airbagis deployed, passengers should sit as uprightas possible, with their feet on the floor andtheir backs against the seat backrest.

WARNING
Volvo recommends contacting an authorizedVolvo workshop for repairs. Incorrectly per-formed repairs to the airbag system couldimpair function and lead to serious injury.

The front airbag system

sors that activate the gas generators, causing theairbags to be inflated with nitrogen gas.
As the movement of the seats' occupants com-presses the airbags, some of the gas is expelledat a controlled rate to provide better cushioning.Both seat belt tensioners also deploy, minimizingseat belt slack. The entire process, from inflationto deflation of the airbag, occurs within tenths ofa second.
The location of the front airbags is indicated bySRS AIRBAG embossed on the steering wheelpad and above the glove compartment, and bydecals on both sun visors and on the front andfar right side of the dash.
The driver's side front airbag is folded andlocated in the steering wheel hub.
The knee airbag is folded on the underside ofthe dashboard on the driver's side. The textAIRBAG is embossed on the panel.
The passenger's side front airbag is foldedbehind a panel located above the glove compart-ment.

WARNING
•The airbags in the vehicle are designed tobe a SUPPLEMENT to-not a replacementfor-the three-point seat belts. For maxi-mum protection, wear seat belts at alltimes. Be aware that no system can pre-vent all possible injuries that may occur inan accident.
•Never drive with your hands on the steer-ing wheel pad/airbag housing.
•The front airbags are designed to helpprevent serious injury. Deployment occursvery quickly and with considerable force.During normal deployment and depend-ing on variables such as seating position,one may experience abrasions, bruises,swellings, or other injuries as a result ofdeployment of one or both of the airbags.
•When installing any accessory equipment,make sure that the front airbag system isnot damaged. Any interference in the sys-tem could cause malfunction.

Front airbag deployment
•The front airbags are designed to deploy dur-ing certain frontal or front-angular collisions,impacts, or decelerations, depending on thecrash severity, angle, speed and objectimpacted. The airbags may also deploy in
certain non-frontal collisions where rapiddeceleration occurs.
•The airbag system sensors, which trigger thefront airbags, are designed to react to boththe impact of the collision and the inertialforces generated by it, and to determine ifthe intensity of the collision is sufficient forthe seat belt tensioners and/or airbags to bedeployed.
However, not all frontal collisions activate thefront airbags.
•If the collision involves a nonrigid object (e.g.,a snow drift or bush), or a rigid, fixed objectat a low speed, the front airbags will not nec-essarily deploy.
•Front airbags do not normally deploy in aside impact collision, in a collision from therear or in a rollover situation.
•The amount of damage to the bodyworkdoes not reliably indicate if the airbagsshould have deployed or not.
