YOUR VOLVO
34Canadian market only: This vehicle is equipped with an “Event Data Recorder” (EDR). The main purpose of theEDR is to register and record data in trafficaccidents or accident-like situations, e.g. if anairbag deploys or if the vehicle hits an obstaclein the road. This data is recorded in order tohelp understand how the vehicle's systemsperform in these types of situations. The EDRis designed to record data related to vehicledynamics and safety systems for a shortperiod of time, usually 30 seconds or less. The EDR in this vehicle is designed to record data in traffic accidents or accident-like situa-tions such as:
How the various systems in the vehicleperformed;
Whether the driver and passenger seatbelts were tightened/buckled;
The driver's use of the accelerator/brakepedal;
How fast the vehicle was moving.
This data can help provide a better under-standing of the circumstances in which trafficaccidents and injuries occur. The EDR records data only if a non-trivial accident situation occurs. EDR does not record any data duringnormal driving conditions. The system alsonever registers data on who is driving the vehi-cle or the geographical location of the acci- dent or near-accident. However, other parties,such as law enforcement, could combine theEDR data with the type of personally identifia-ble information that is routinely acquired dur-ing an accident investigation. Special equip-ment and access to either the vehicle or theEDR is required to read this recorded data. In addition to the EDR, the vehicle is equipped with a number of computers that continuouslycontrol and monitor the vehicle's performance.These computers may record data during nor-mal driving conditions, particularly if theydetect a fault relating to the vehicle's opera-tion and functionality or upon activation of thevehicle's active driver support functions (e.g.City Safety or the auto-brake function). Some of this recorded data is required by technicians performing service and mainte-nance in order to diagnose and rectify anyfaults that may have occurred in the vehicle.The recorded information is also needed toenable Volvo to fulfill legal and other regula-tory requirements. Information registered inthe vehicle is stored in its computers until thevehicle is serviced or repaired. In addition to the above, the recorded informa- tion may be used in aggregated form forresearch and product development purposesin order to continuously improve the safetyand quality of Volvo vehicles.
Volvo will not provide this information to anythird parties without the vehicle owner's con-sent. However, national legislation and regula-tions may require Volvo to disclose this type ofinformation to law enforcement or otherauthorities that can claim a legal right to theinformation. Special technical equipment,which Volvo and workshops that have enteredagreements with Volvo have access to, isrequired to read and interpret the recordeddata. Volvo is responsible for ensuring thatinformation provided to Volvo in conjunctionwith service and maintenance is stored andhandled securely and in compliance withapplicable legal requirements. For more infor-mation, please contact a Volvo retailer.

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 con-venient to install child seats. Some restraint systems for children are designed to be secured in the vehicle by lapbelts or the lap portion of a lap-shoulder belt.Such child restraint systems can help protectchildren in vehicles in the event of an accidentonly if they are used properly. However, chil-dren could be endangered in a crash if thechild restraints are not properly secured in thevehicle. Failure to follow the installationinstructions for your child restraint can resultin your child striking the vehicle's interior in asudden stop. Holding a child in your arms is NOT a suitable substitute for a child restraint system. In anaccident, a child held in a person's arms canbe crushed between the vehicle's interior andan unrestrained person. The child could alsobe injured by striking the interior, or by being ejected from the vehicle during a suddenmaneuver or impact. The same can also hap-pen if the infant or child rides unrestrained onthe seat. Other occupants should also beproperly restrained to help reduce the chanceof injuring or increasing the injury of a child. All states and provinces have legislation gov- erning how and where children should be car-ried in a vehicle. Find out the regulations exist-ing in your state or province. Recent accidentstatistics have shown that children are safer inrear seating positions than front seating posi-tions when properly restrained. A childrestraint system can help protect a child in avehicle. Here's what to look for when selectinga child restraint system: It should have a label certifying that it meets applicable Federal Motor Vehicle SafetyStandards (FMVSS 213) - or in Canada,CMVSS 213. Make sure the child restraint system is approved for the child's height, weight anddevelopment - the label required by the stand-ard or regulation, or instructions for infantrestraints, typically provide this information. In using any child restraint system, we urge you to carefully look over the instructions thatare provided with the restraint. Be sure youunderstand them and can use the device prop-erly and safely in this vehicle. A misused childrestraint system can result in increased inju-

Volvo has some very specific recommendations
Always wear your seat belt.
Airbags are a SUPPLEMENTAL safety device which, when used with a three-point seat belt can help reduce seriousinjuries during certain types of accidents.Volvo recommends that you do not dis-connect the airbag system in your vehicle.
Volvo strongly recommends that everyonein the vehicle be properly restrained.
Volvo recommends that ALL occupants(adults and children) shorter than 140 cm(4 feet 7 inches) be seated in the rear seatof any vehicle with a front passenger sideairbag.
Drive safely!

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 systems: infant seats, convertible seats andbooster cushions. They are classified accord-ing to the child's age and size. The child restraint should be secured using a three-point seat belt, ISOFIX/LATCH anchorsor top tether anchors.
Convertible seat
WARNING
A child seat should never be used in the front passenger seat of any vehicle with afront passenger airbag - not even if the"Passenger airbag off" symbol near therear-view mirror is illuminated. If theseverity of an accident were to cause theairbag to inflate, this could lead to seriousinjury or death to a child seated in thisposition.

Booster cushion
WARNING
Always refer to the child restraint manufac- turer's instructions for detailed informationon securing the restraint.
WARNING
When not in use, keep the child restraint system secured or remove itfrom the passenger compartment tohelp prevent it from injuring passen-gers in the event of a sudden stop orcollision.
A small child's head represents a con-siderable part of its total weight and itsneck is still very weak. Volvo recom-mends that children up to age 4 travel,properly restrained, facing rearward. Inaddition, Volvo recommends that chil-dren should ride rearward facing, prop-erly restrained, as long as possible.
NOTE
Prolonged installation and use of the child restraint may damage the vehicle's interior.Volvo recommends using the kick guardaccessory to help protect the vehicle'sinterior.
Automatic Locking Retractor/ Emergency Locking Retractor (ALR/ELR)
To make child seat installation easier, each seat belt (except for the driver's belt) is equip-ped with a locking mechanism to help keepthe seat belt taut.
When attaching the seat belt to a child seat:
1. Attach the seat belt to the child seat
according to the child seat manufacturer's instructions.
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 audible at this time and is normal. The belt willnow be locked in place. This function is auto-matically disabled when the seat belt isunlocked and the belt is fully retracted.
WARNING
Do not use child safety seats or child booster cushions/backrests in the frontpassenger's seat. We also recommend thatchildren who have outgrown these devicessit in the rear seat with the seat belt prop-erly fastened.
