possible collision and help the driver act in timeto prevent it. If the driver does not react to thewarning and the risk of collision is determined tobe imminent, City Safety can automatically applythe brakes.
Lane assistance (LKA) is another example of afunction that can help prevent accidents by help-ing the driver - on expressways and similar largerroads - to reduce the risk of the car accidentallyleaving its own lane.
The function Steering aid during increasedcollision risk can help the driver reduce the riskof the car leaving its lane unintentionally and/orcolliding with another vehicle or obstacle byactively steering the car back into its lane and/orswerving.

Protection
To help protect the driver and passengers, thevehicle is equipped with seat belt tensioners thatpull the seat belts taut in collisions and other crit-ical situations. The vehicle also has airbags, inflat-able curtains and the Whiplash ProtectionSystem (WHIPS), which helps prevent whiplashinjuries.

Seat belt tensioners
The vehicle is equipped with standard and elec-tric seat belt tensioners that can help tension theseat belt in a critical situation or collision.

Standard seat belt tensioners
All seat belts are equipped with a standard seatbelt tensioner.
In a collision of sufficiently violent force, the seatbelt tensioners will tension the seat belts in orderto more effectively restrain the occupants.

Electric seat belt tensioners
The driver's and front passenger's seat belts areequipped with electric seat belt tensioners.
The seat belt tensioners interact and can be acti-vated in conjunction with the City Safety andRear Collision Warning driver support systems. Incritical situations, such as if the vehicle brakessuddenly, begins to skid or runs off the road (e.gif the vehicle rolls into a ditch, lifts off the groundor hits an obstacle in the road), or if there is a riskof collision, the seat belts can be pulled taut bythe seat belt tensioner's electric motor.
The electric seat belt tensioner helps to positionthe occupant more effectively in the seat, whichreduces the risk of the occupant striking the inte-rior of the passenger compartment and improvesthe effect of other safety systems such as theairbags.
When a critical situation has passed, the seat beltand the electric seat belt tensioner are resetautomatically. However, they can also be resetmanually.
WARNING
Never attempt to alter or repair the seat belton your own. Volvo recommends contactingan authorized Volvo workshop.
If the seat belt has been exposed to extremeforces, e.g. in conjunction with a collision, theentire seat belt must be replaced. Even if theseat belt appears undamaged, some of itsprotective properties may have been lost. Alsoreplace the seat belt if it is worn or damaged.The new seat belt must be type approved andintended for the same seating position as thereplaced seat belt.

Hybrid gauge
The hybrid battery gauge shows how much cur-rent is left in the hybrid battery.
The current in the hybrid battery is used to powerthe electric motor, but can also be used to heator cool the vehicle. The trip computer calculatesan approximate driving distance with the remain-ing current in the hybrid battery.
