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.

WARNING
Do not squeeze box-like cargo between therear seat cushion and the front seat backrest.
If the rear seat backrests are folded down,cargo must be secured to prevent it from slid-ing forward against the front seat backrests inthe event of a collision.

WARNING
If a rear seat backrest is folded down or if arear-facing child restraint is being used in therear seat, the seat in front must be moved for-ward so that it does not come into contactwith the backrest or child restraint.

Seating position
For WHIPS to provide optimal protection, thedriver and passenger must be seated correctlyand the system's function must not be impededin any way.
Set the front seat to the correct seating positionbefore starting to drive.
The driver and the front seat passenger shouldsit in the center of the seat with their heads asclose as possible to the head restraints.

Seat belts should always be worn by all occu-pants in your vehicle. Children should be prop-erly restrained using an infant seat, adjustablechild seat or booster cushion as determined byage, weight and height.
Most states and provinces make it mandatory foroccupants of a vehicle to use seat belts.
Seat belt maintenance
Check periodically that the seat belts are in goodcondition. Use water and a mild detergent forcleaning. Check the seat belt mechanism's func-tion as follows: attach the seat belt and pull rap-idly on the strap.

Recovery (p. 489) 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, a
child should always be properly restrained in a
vehicle.
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 the
lap portion of a lap-shoulder belt. Such child
restraint systems can help protect children in
vehicles in the event of an accident only if they
are used properly. However, children could be
endangered in a crash if the child restraints are
not properly secured in the vehicle. Failure to fol-
low the installation instructions for your child
restraint 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 be
crushed between the vehicle's interior and an
unrestrained person. The child could also be
injured by striking the interior, or by being ejected
from the vehicle during a sudden maneuver or impact. The same can also happen if the infant or
child rides unrestrained on the seat. Other occu-
pants should also be properly restrained to help
reduce the chance of injuring or increasing the
injury of a child.
All states and provinces have legislation govern-
ing how and where children should be carried in
a vehicle. Find out the regulations existing in your
state or province. Recent accident statistics have
shown that children are safer in rear seating
positions than front seating positions when prop-
erly restrained. A child restraint system can help
protect a child in a vehicle. Here's what to look
for 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 are
provided with the restraint. Be sure you under-
stand them and can use the device properly and
safely in this vehicle. A misused child restraint
system can result in increased injuries for both
the infant or child and other occupants in the
vehicle.

Child restraint systems Infant seat
There are three main types of child restraint sys-
tems: infant seats, convertible seats and booster
cushions. They are classified according to the
child's age and size.
The child restraint should be secured using a
three-point seat belt, ISOFIX/LATCH anchors or
top tether anchors. Convertible seat
WARNING
A child seat should never be used in the front
passenger seat of any vehicle with a front
passenger airbag - not even if the "Passenger
airbag off" symbol near the rear-view mirror is
illuminated. If the severity of an accident were
to cause the airbag to inflate, this could lead
to serious injury or death to a child seated in
this position.

Booster cushion
WARNING
Always refer to the child restraint manufactur-
er's instructions for detailed information on
securing the restraint.
WARNING
When not in use, keep the child restraint
system secured or remove it from the
passenger compartment to help prevent it
from injuring passengers in the event of a
sudden stop or collision.
A small child's head represents a consid-
erable part of its total weight and its neck
is still very weak. Volvo recommends that
children up to age 4 travel, properly
restrained, facing rearward. In addition,
Volvo recommends that children should
ride 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 with
a locking mechanism to help keep the seat belt
taut.
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 now
be locked in place. This function is automatically
disabled when the seat belt is unlocked and the
belt is fully retracted.
WARNING Do not use child safety seats or child booster
cushions/backrests in the front passenger's
seat. We also recommend that children who
have outgrown these devices sit in the rear
seat with the seat belt properly fastened.
Child restraint registration and recallsChild restraints could be recalled for safety rea-
sons. You must register your child restraint to be
reached in a recall. To stay informed about child
safety seat recalls, be sure to fill out and return
the registration card that comes with new child
restraints.
Child restraint recall information is readily availa-
ble in both the U.S. and Canada. For recall infor-
mation in the U.S., call the U.S. Government's
Auto Safety Hotline at 1-800-424-9393 or go to
