Volvo Structural Parts Statement
Volvo has always been and continues to be a leader in automotive safety.
Volvo engineers and manufactures vehicles designed to help protect vehicle occupants in theevent of a collision. Volvos are designed to absorb the impact of a collision. This energy absorption system including,but not limited to, structural components such asbumper reinforcement bars, bumper energyabsorbers, frames, rails, fender aprons, A-pillars,B-pillars and body panels must work together tomaintain cabin integrity and protect the vehicleoccupants. The supplemental restraint system including but not limited to air bags, side curtain air bags, anddeployment sensors work together with theabove components to provide proper timing forair bag deployment. Due to the above, Volvo Car USA does not sup- port the use of aftermarket, alternative or any-thing other than original Volvo parts for collisionrepair. Volvo Car USA also recommends using Volvo- approved replacement glass. The use of after-market glass, particularly a windshield, can havean adverse effect on collision avoidance andadvanced lighting systems. In addition Volvo does not support the use or re- use of structural components from an existing vehicle that has been previously damaged.Although these parts may appear equivalent, it isdifficult to tell if the parts have been previouslyreplaced with non-OE parts or if the part hasbeen damaged as a result of a prior collision. Thequality of these used parts may also have beenaffected due to environmental exposure.

Occupant safety Safety is Volvo's cornerstone.
Volvo's concern for safetyOur concern for safety dates back to 1927 when the first Volvo rolled off the production line.Three-point seat belts (a Volvo invention), safetycages, and energy-absorbing impact zones weredesigned into Volvo vehicles long before it wasfashionable or required by government regulation. We will not compromise our commitment to safety. We continue to seek out new safety fea-tures and to refine those already in our vehicles.You can help. We would appreciate hearing yoursuggestions about improving automobile safety.We also want to know if you ever have a safetyconcern with your vehicle.

Whiplash protection system
The Whiplash protection system (WHIPS) con- sists of specially designed hinges and bracketson the front seat backrests designed to helpabsorb some of the energy generated in a colli-sion from the rear (when the vehicle is rear-ended).
FunctionIn the event of certain rear-end collisions, the hinges and brackets of the front seat backrestsare designed to change position slightly to allowthe backrest/head restraint to help support theoccupant's head before moving slightly rearward.This movement helps absorb some of the forcesthat could result in whiplash.
WARNING
• The WHIPS system is designed to sup- plement the other safety systems in yourvehicle. For this system to function prop-erly, the three-point seat belt must beworn. Please be aware that no systemcan prevent all possible injuries that mayoccur in an accident.
• The WHIPS system is designed to func-tion in certain collisions from the rear,depending on the crash severity, angleand speed.
WARNING
•
Occupants in the front seats must never sit out of position. The occupant's backmust be as upright as comfort allows andbe against the seat back with the seatbelt properly fastened.
• If your vehicle has been involved in a rear-end collision, the front seat backrestsmust be inspected by a trained and quali-fied Volvo service technician, even if theseats appear to be undamaged. Certaincomponents in the WHIPS system mayneed to be replaced.
• Do not attempt to service any componentin the WHIPS system yourself.
WARNING
•Boxes, suitcases, etc. wedged behind the front seats could impede the function ofthe Whiplash Protection System.
• If the rear seat backrests are foldeddown, cargo must be secured to preventit from sliding forward against the frontseat backrests in the event of a collisionfrom the rear. This could interfere withthe action of the Whiplash ProtectionSystem.

Seat belt pretensioners The vehicle's seat belts are equipped with stand- ard and electric pretensioners that can help pullthe seat belts taut in a critical situation or a colli-sion. Some or all of the pretensioners will betriggered in certain types of collisions, depend-ing on the direction and severity of the impact.
Reversible seat belt pretensionersReversible seat belt pretensioners is a system in the front seats that pulls the seat belts slightlytaut prior to a collision. This function helps posi-tion the front seat occupants to help improve theeffects of other safety systems, e.g., the airbagsystem.
Seat belt pretensioners in collisionsThe seat belts are equipped with standard pre-tensioners that are triggered according to theseverity of a collision.
Seat belt pretensioners in critical
situations
In addition to the standard pretensioners, theseat belts in the front seats are also equippedwith electric pretensioners. The pretensioners interact and can be triggered along with the City Safety and Rear CollisionWarning systems. In critical situations such assudden braking, evasive maneuvers, etc., the seatbelt can be pulled taut by the pretensioner'selectric motor. The electric pretensioner positions the occupantin the seat to help reduce the risk of striking theinterior of the passenger compartment andimproves the effect of other safety systems suchas the airbags.
Resetting the electric pretensioners
When a critical situation has passed, the seat belt and the electric pretensioner are reset automati-cally. If the seat belt should remain taut:
1. Stop the vehicle safely.
2. Unbuckle the seat belt and rebuckle it.
> The seat belt and the electric preten-sioner will be reset.
WARNING
• Never repair the belt yourself; have this work done by a trained and qualifiedVolvo service technician only.

Airbag system As an enhancement to the three-point seat belts, your vehicle is equipped with an airbag system.
WARNING
•If the airbag warning light stays on after the engine has started or if it illuminateswhile you are driving, have the vehicleinspected by a trained and qualified Volvoservice technician as soon as possible.
• Never try to repair any component or partof the airbag systems yourself. Any inter-ference in the system could cause mal-function and serious injury. All work onthese systems should be performed by atrained and qualified Volvo service techni-cian.
WARNING
If your vehicle has become flood-damaged in any way (e.g., soaked carpeting/standingwater on the floor of the vehicle), do notattempt to start the vehicle. This may causeairbag deployment which could result in seri-ous injury. Have the vehicle towed to a trainedand qualified Volvo service technician forrepairs. Before attempting to tow the vehicle:
1. Switch off the ignition for at least
10 minutes and disconnect the battery.
2. Follow the instructions in the digital own- ers' information for manually overriding the shiftlock system.
Deployed airbags
WARNING
If any of the airbags have deployed:
• Do not attempt to drive the vehicle. Have it towed to a qualified repair facility.
• If necessary seek medical attentIon.
Driver/passenger side airbags
The front airbags supplement the three-point seat belts. For these airbags to provide the pro-tection intended, seat belts must be worn at alltimes.
Driver and passenger side front airbags
The front airbag systemThe front airbag system includes gas generators surrounded by the airbags, and deceleration sen-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 pretensioners also deploy, mini-mizing seat belt slack. The entire process, includ-ing inflation and deflation of the airbags, takesapproximately one fifth of a second.
