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.

SAFETY
50

WARNING
Never use a seat belt for more than oneoccupant. Never wear the shoulder portion ofthe belt under the arm, behind the back orotherwise out of position. Such use couldcause injury in the event of an accident. Asseat belts lose much of their strength whenexposed to violent stretching, they should bereplaced after any collision, even if theyappear to be undamaged.

WARNING
Do not use clips or fasten the belts aroundhooks or other parts of the interior. This willprevent the seat belt from fitting properly.

WARNING
Never damage the seat belts and never insertany foreign objects into the belt buckle. Thismay cause the seat belts and belt buckles tomalfunction in a collision. There is a risk ofserious injury.

Unbuckling seat belts
1. Press the red button on the seat belt recep-tacle and make sure the seat belt retractsfully into the retractor slot.
2. If it does not fully retract, guide the belt man-ually into the slot and make sure it does nothang loose.
If the seat belt in the second row centerseating position is used, make sure it is prop-erly positioned in the correct seat belt guide.

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.

84 Instrument panel
The instrument panel displays information rela-
ted to the vehicle and driving. The instrument panel contains gauges, indicators
and monitoring and warning symbols. What is
shown in the instrument panel varies depending
on the equipment, settings and functions cur-
rently active.
The instrument panel is activated as soon as a
door is opened, i.e. in ignition mode 0. The panel
will power down after a short period of time if it is
not used. To reactivate it, do one of the following:
• Depress the brake pedal.
• Activate ignition mode I. •
Open one of the doors.
WARNING If the instrument panel is not functioning
properly, information about brakes, airbags or
other safety-related systems may not be dis-
played. The driver will then not be able to
check the status of the vehicle systems or
receive relevant warnings and information.
WARNING
If the instrument panel turns off, does not
activate when the ignition is switched on, or
part/all of the panel cannot be read, do not
drive the vehicle. Consult a workshop immedi-
ately. Volvo recommends an authorized Volvo
workshop.

The hybrid battery gauge shows how much cur-
rent is left in the hybrid battery. The current in the hybrid battery is used to power
the electric motor, but can also be used to heat
or cool the vehicle. The trip computer calculates
an approximate driving distance with the remain-
ing current in the hybrid battery.
Symbols in the hybrid battery gauge The symbol in the hybrid battery gauge indi-
cates that the Hold function is activated. The symbol indicates that the
