Canadian market only:
This vehicle is equipped with an “Event DataRecorder” (EDR). The main purpose of the EDRis to register and record data in traffic accidentsor accident-like situations, e.g. if an airbagdeploys or if the vehicle hits an obstacle in theroad. This data is recorded in order to help under-stand how the vehicle's systems perform in thesetypes of situations. The EDR is designed torecord data related to vehicle dynamics andsafety systems for a short period of time, usually30 seconds or less.
The EDR in this vehicle is designed to recorddata in traffic accidents or accident-like situationssuch as:
How the various systems in the vehicle per-formed;
Whether the driver and passenger seat beltswere tightened/buckled;
The driver's use of the accelerator/brakepedal;
How fast the vehicle was moving.
This data can help provide a better understandingof the circumstances in which traffic accidentsand injuries occur. The EDR records data only if anon-trivial accident situation occurs. EDR doesnot record any data during normal driving condi-tions. The system also never registers data onwho is driving the vehicle or the geographicallocation of the accident or near-accident. How-
ever, other parties, such as law enforcement,could combine the EDR data with the type of per-sonally identifiable information that is routinelyacquired during an accident investigation. Specialequipment and access to either the vehicle or theEDR is required to read this recorded data.
In addition to the EDR, the vehicle is equippedwith a number of computers that continuouslycontrol and monitor the vehicle's performance.These computers may record data during normaldriving conditions, particularly if they detect afault relating to the vehicle's operation and func-tionality or upon activation of the vehicle's activedriver support functions (e.g. City Safety or theauto-brake function).
Some of this recorded data is required by techni-cians performing service and maintenance inorder to diagnose and rectify any faults that mayhave occurred in the vehicle. The recorded infor-mation is also needed to enable Volvo to fulfilllegal and other regulatory requirements. Informa-tion registered in the vehicle is stored in its com-puters until the vehicle is serviced or repaired.
In addition to the above, the recorded informationmay be used in aggregated form for research andproduct development purposes in order to contin-uously improve the safety and quality of Volvovehicles.
Volvo will not provide this information to any thirdparties without the vehicle owner's consent. How-ever, national legislation and regulations may
require Volvo to disclose this type of informationto law enforcement or other authorities that canclaim a legal right to the information. Specialtechnical equipment, which Volvo and workshopsthat have entered agreements with Volvo haveaccess to, is required to read and interpret therecorded data. Volvo is responsible for ensuringthat information provided to Volvo in conjunctionwith service and maintenance is stored and han-dled securely and in compliance with applicablelegal requirements. For more information, pleasecontact a Volvo retailer.

Child safety
Children should always be seated safely whentraveling in the vehicle.

General information
Volvo recommends the proper use of restraintsystems 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 designedto 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 suitablesubstitute 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 meetsapplicable Federal Motor Vehicle Safety Stand-ards (FMVSS 213) - or in Canada, CMVSS 213.
Make sure the child restraint system is approvedfor 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 youto 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 cushionand backrest can be obtained from your Volvoretailer. See also the article "Integrated boostercushion."

Child restraints
Suitable child restraints should always be usedwhen 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 athree-point seat belt, ISOFIX/LATCH anchors ortop tether anchors.
Convertible seat

WARNING
A child seat should never be used in the frontpassenger seat of any vehicle with a frontpassenger airbag - not even if the "Passengerairbag off" symbol near the rear-view mirror isilluminated. If the severity of an accident wereto cause the airbag to inflate, this could leadto serious injury or death to a child seated inthis position.
Booster cushion
WARNING
Always refer to the child restraint manufactur-er's instructions for detailed information onsecuring the restraint.

WARNING
When not in use, keep the child restraintsystem 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 seatbelt (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 aroundthe 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 boostercushions/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.

Child restraint registration and recalls
Child restraints could be recalled for safety rea-sons. You must register your child restraint to bereached in a recall. To stay informed about childsafety seat recalls, be sure to fill out and returnthe registration card that comes with new childrestraints.
Child restraint recall information is readily availa-ble in both the U.S. and Canada.
