Seatbelt
Heavy braking can have serious consequences if the seatbelts are not used.
It is important that the seatbelt lies against the body so it can provide maximum protection. Donot lean the backrest too far back. The seatbelt isdesigned to protect in a normal seating position.
WARNING
Remember not to clip or hook the seatbelt to hooks or other interior fittings, as this pre-vents the belt from tightening properly.
WARNING
The seatbelts and airbags interact. If a seat- belt is not used or is used incorrectly, this maydiminish the protection provided by the airbagin the event of a collision.
WARNING
Never modify or repair the seatbelts yourself. Volvo recommends that an authorised Volvoworkshop should be contacted. If the seatbelt has been subjected to a major load, such as in conjunction with a collision,the entire seatbelt must be replaced. Some ofthe seatbelt's protective properties may havebeen lost even if the seatbelt does not appeardamaged. The seatbelt must also be replacedif it shows signs of wear or damage. The newseatbelt must be type-approved and designedfor installation at the same location as thereplaced seatbelt.

Seatbelt tensioner
The car is fitted with pyrotechnic and electric seatbelt tensioners that can tension the seat-belts in critical situations and collisions.
Seatbelt tensioner during collisionAll the seatbelts are equipped with a pyrotechnic seatbelt tensioner. The pyrotechnic seatbelt tensioner tensions the seatbelt in the event of a collision with sufficientforce in order to more effectively restrain theoccupant.
Seatbelt tensioner during critical
situations
The driver and front passenger seatbelts areequipped with an electric seatbelt tensioner. The seatbelt tensioners work together and can be activated together with the driver support sys-tems City Safety and Rear Collision Warning. Incritical situations, such as panic braking, sharpevasive action, driving off the road (e.g. the carrolls over into a ditch, lifts off the ground or hitssome off-road object), skidding, or risk of colli-sion, the seatbelt can be tensioned by the seat-belt tensioner's electric motor. The electric seatbelt tensioner adjusts the occu- pant to a better position, reducing the risk ofstriking the car's interior and improving the effectof safety systems, such as the car's airbags.

IMPORTANT
If the passenger airbag is deactivated, the electric seatbelt tensioner on the passengerside will also be deactivated.
Resetting the electric seatbelt tensioner
Once the critical situation has passed, the seat- belt and electric seatbelt tensioner are resetautomatically. If the belt still remains tensioned:
1. Stop the car at a safe place.
2. Unfasten the seatbelt and then refasten it.
> The seatbelt and electric seatbelt ten-sioner are reset.
WARNING
Never modify or repair the seatbelts yourself. Volvo recommends that an authorised Volvoworkshop should be contacted.

Fastening/unfastening a seatbelt
Make sure that all passengers have fastened their seatbelts before starting to drive.
Fastening a seatbelt1. Pull out the seatbelt slowly and make sure it is not twisted or damaged.
NOTE
The seatbelt locks and cannot be withdrawn:
• if it is pulled out too quickly
• during braking and acceleration
• if the car leans heavily.
2. Lock the belt by inserting the locking tab in
the intended buckle.
> A loud "click" indicates that the belt haslocked.
WARNING
Always insert the tongue of the seatbelt into the buckle on the correct side. The seatbeltsand buckles would otherwise possibly notfunction as intended in the event of a colli-sion. There is a risk of serous injury.

SAFETY

3. In the front seats the seatbelt can be
adjusted for height.
Press together the seat mounting and move the seatbelt up or down. Position the belt as high as possible without it chafing against your throat.
The seatbelt must pass over the shoulder (not down over the arm).
4. Tension the hip strap over the lap by pullingthe diagonal shoulder belt up towards the shoulder.
The hip strap must be positioned low down (not over the abdomen).
WARNING
Each seatbelt is designed for only one person.
WARNING
Remember not to clip or hook the seatbelt to hooks or other interior fittings, as this pre-vents the belt from tightening properly.
WARNING
Do not make any damages on seatbelts nor insert any foreign objects into a buckle. Theseatbelts and buckles would then possibly notfunction as intended in the event of a colli-sion. There is a risk of serous injury.
Unfastening a seatbelt1. Press the red button on the seatbelt buckle and then let the belt retract.
2. If the seatbelt does not retract fully, feed it in by hand so that it does not hang loose.

Airbags
The car is equipped with airbags and inflatable curtains for driver and passengers.
WARNING
The airbag system's control module is located in the centre console. If the centre console isdrenched with water or other liquid, discon-nect the cables to the starter battery. Do notattempt to start the car since the airbags maydeploy. Recovering the car. Volvo recom-mends that it is transported to an authorisedVolvo workshop.
Deployed airbagsIf any of the airbags have deployed, the following is recommended:
• Recovering the car. Volvo recommends that itis transported to an authorised Volvo work-shop. Do not drive with deployed airbags.
• Volvo recommends engaging an authorisedVolvo workshop to handle the replacement ofcomponents in the car's safety systems.
• Always contact a doctor.
WARNING
Never drive with deployed airbags. They can make steering difficult. Other safety systemsmay also be damaged. The smoke and dustcreated when the airbags are deployed cancause skin and eye irritation/injury after inten-sive exposure. In case of irritation, wash withcold water. The rapid deployment sequenceand airbag fabric may cause friction and skinburns.

Driver and passenger airbags As a supplement to the seatbelts, the vehicle is equipped with airbags on the driver and passen-ger sides in the front seat.
Driver and passenger airbags1
.
In the event of a frontal collision, the airbags help to protect the head, face and chest of the driver and passenger as well as the knees and legs 1
of
the driver. A sufficiently violent collision trips the sensors and the airbag/airbags is inflated. The airbagcushions the initial collision impact for the occu-pant. The airbag deflates when compressed bythe collision. When this occurs, smoke escapesinto the car. This is completely normal. The entire process, including inflation and deflation of theairbag, occurs within tenths of a second.
NOTE
The detectors react differently depending on the nature of the collision and whether or notthe seatbelts are fastened. Applies to all beltpositions. It is therefore possible that only one (or none) of the airbags may inflate in a collision. Thedetectors sense the force of the collision onthe vehicle and the action is adapted accord-ingly so that none, one or more airbags aredeployed.
WARNING
The seatbelts and airbags interact. If the belt is not used or is used incorrectly, this maydiminish the protection provided by the airbagin the event of a collision. To minimise the risk of injury if the airbag deploys, passengers must sit as upright aspossible with their feet on the floor and backsagainst the backrest.
WARNING
Volvo recommends that an authorised Volvo workshop should be contacted for repair.Defective work in the airbag system couldcause malfunction and result in serious per-sonal injury.

Side airbag
The side airbags on the driver and passenger seats protect the chest and hip in the event of acollision.
The side airbags are fitted in the outer backrest frames of the front seats and help to protect thedriver and passengers in the front seat. A sufficiently violent collision trips the sensors and the side airbags are inflated. The airbaginflates between the occupant and the doorpanel and thereby cushions the initial impact. Theairbag deflates when compressed by the collision.The side airbag is normally only deployed on theside of the collision.
WARNING
Volvo recommends that an authorised Volvo workshop should be contacted for repair.Defective work in the side airbag systemcould cause malfunction and result in seriouspersonal injury.
WARNING
Do not put objects in the area between the outside of the seat and the door panel, sincethis area is required by the side airbag. Volvo recommends the use only of car seat covers approved by Volvo. Other seat coversmay impede the operation of the side airbags.
WARNING
Side airbags are a supplement the seatbelts. Always use a seatbelt.
Side airbag and child seatsThe protection provided by the car to children seated in a child seat or on a booster cushion isnot diminished by the side airbag.
