possible collision and help the driver act in time to 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 a function 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 increased
collision risk can help the driver reduce the risk
of the car leaving its lane unintentionally and/or colliding with another vehicle or obstacle byactively steering the car back into its lane and/orswerving.
ProtectionTo 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 one occupant. 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 around hooks or other parts of the interior. This willprevent the seat belt from fitting properly.
WARNING
Never damage the seat belts and never insert any 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 belts1. Press the red button on the seat belt recep-tacle and make sure the seat belt retracts fully 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 center seating 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 tensionersAll seat belts are equipped with a standard seat belt tensioner. In a collision of sufficiently violent force, the seat belt tensioners will tension the seat belts in orderto more effectively restrain the occupants.
Electric seat belt tensionersThe 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 position the 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.

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. •

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 power the 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.
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 Charge function
is activated.
