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.

For example:
The vehicle has been started, but is stationary and no
power is being requested.
The electric motor cannot supply the requested power
and the internal combustion engine will start. The vehicle is generating current to recharge the battery,
e.g. during light braking or engine braking on a down-
slope.

resistance
Speed-dependent power steering increases the
steering wheel resistance in pace with the vehi-
cle's speed to give the driver an enhanced feel-
ing of control and stability.
Steering may feel stiffer on highways. When
parking and at low speeds, it will be easier to
move the steering wheel.
NOTE In some situations, the power steering may
become too hot and require temporary cool-
ing – during such time the power steering will
work at reduced output and the steering
wheel may feel more difficult to move.
In parallel with the temporarily reduced steer-
ing assistance, the driver display shows a
message as well as a STEERING WHEEL
symbol.
WARNING
While the power steering is working at
reduced power, the driver support functions
and systems with steering assistance are not
available.
In such a situation, the driver display shows
the
Power steering failure message, com-
bined with a STEERING WHEEL symbol.

Control
The Roll Stability Control (RSC 1
) system helps
minimize the risk of a rollover in the event of e.g.
a sudden evasive maneuver or if the vehicle
begins to skid.
The RSC system monitors the lateral angle at
which the vehicle is leaning and registers any
changes. Using this information, the system cal-
culates the likelihood of a rollover. If there is an
imminent risk of a rollover, Electronic Stability
Control is activated, engine torque is reduced and
brakes are applied to one or more of the wheels
until the vehicle has regained stability.
