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.

Child safety
Children should always be seated safely when traveling in the vehicle.
General informationVolvo recommends the proper use of restraint systems for all occupants including children.Remember that, regardless of age and size, achild should always be properly restrained in avehicle. Your vehicle is also equipped with ISOFIX/ LATCH attachments, which make it more conven-ient to install child seats. Some restraint systems for children are designed to be secured in the vehicle by lap belts or thelap portion of a lap-shoulder belt. Such childrestraint systems can help protect children invehicles in the event of an accident only if theyare used properly. However, children could beendangered in a crash if the child restraints arenot properly secured in the vehicle. Failure to fol-low the installation instructions for your childrestraint can result in your child striking the vehi-cle's interior in a sudden stop. Holding a child in your arms is NOT a suitable substitute for a child restraint system. In an acci-dent, a child held in a person's arms can becrushed between the vehicle's interior and anunrestrained person. The child could also beinjured by striking the interior, or by being ejectedfrom the vehicle during a sudden maneuver or impact. The same can also happen if the infant orchild rides unrestrained on the seat. Other occu-pants should also be properly restrained to helpreduce the chance of injuring or increasing theinjury of a child. All states and provinces have legislation govern- ing how and where children should be carried ina vehicle. Find out the regulations existing in yourstate or province. Recent accident statistics haveshown that children are safer in rear seatingpositions than front seating positions when prop-erly restrained. A child restraint system can helpprotect a child in a vehicle. Here's what to lookfor when selecting a child restraint system: It should have a label certifying that it meets applicable Federal Motor Vehicle Safety Stand-ards (FMVSS 213) – or in Canada, CMVSS 213. Make sure the child restraint system is approved for the child's height, weight and development –the label required by the standard or regulation,or instructions for infant restraints, typically pro-vide this information. In using any child restraint system, we urge you to carefully look over the instructions that areprovided with the restraint. Be sure you under-stand them and can use the device properly andsafely in this vehicle. A misused child restraintsystem can result in increased injuries for boththe infant or child and other occupants in thevehicle.
When a child has outgrown the child safety seat,you should use the rear seat with the standardseat belt fastened. The best way to help protectthe child here is to place the child on a cushionso that the seat belt is properly located on thehips. Legislation in your state or province maymandate the use of a child seat or cushion incombination with the seat belt, depending on thechild's age and/or size. Please check local regu-lations. A specially designed and tested booster cushion and backrest can be obtained from your Volvoretailer. See also the article "Integrated boostercushion."

Child restraints
Suitable child restraints should always be used when children travel in the vehicle.
Child restraint systems
Infant seat
There are three main types of child restraint sys- tems: infant seats, convertible seats and boostercushions. They are classified according to thechild's age and size. The child restraint should be secured using a three-point seat belt, ISOFIX/LATCH anchors ortop tether anchors.
Convertible seat
WARNING
A child seat should never be used in the front passenger seat of any vehicle with a frontpassenger airbag – not even if the "Passen-ger airbag off" symbol near the rear-view mir-ror is illuminated (on vehicles equipped withOccupant Weight Sensor). If the severity of anaccident were to cause the airbag to inflate,this could lead to serious injury or death to achild seated in this position.
Booster cushion

WARNING
•When not in use, keep the child restraint system secured or remove it from thepassenger compartment to help prevent itfrom injuring passengers in the event of asudden stop or collision.
• A small child's head represents a consid-erable part of its total weight and its neckis still very weak. Volvo recommends thatchildren up to age 4 travel, properlyrestrained, facing rearward. In addition,Volvo recommends that children shouldride rearward facing, properly restrained,as long as possible.
Automatic Locking Retractor/ Emergency Locking Retractor (ALR/ELR)
To make child seat installation easier, each seat belt (except for the driver's belt) is equipped witha locking mechanism to help keep the seat belttaut.
When attaching the seat belt to a child seat:
1. Attach the seat belt to the child seat accord-
ing to the child seat manufacturer's instruc- tions.
2. Pull the seat belt out as far as possible.
3. Insert the seat belt latch plate into the buckle (lock) in the usual way. 4. Release the seat belt and pull it taut around
the child seat.
A sound from the seat belt retractor will be audi- ble at this time and is normal. The belt will nowbe locked in place. This function is automaticallydisabled when the seat belt is unlocked and thebelt is fully retracted.
WARNING
Do not use child safety seats or child booster cushions/backrests in the front passenger'sseat. We also recommend that children whohave outgrown these devices sit in the rearseat with the seat belt properly fastened.
