SAFETY

WARNING
Never use a seat belt for more than one occupant. Never wear the shoulder portionof the belt under the arm, behind the backor otherwise out of position. Such usecould cause injury in the event of an acci-dent. As seat belts lose much of theirstrength when exposed to violent stretch-ing, they should be replaced after any colli-sion, even if they appear 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 beltbuckle. This may cause the seat belts andbelt buckles to malfunction in a collision.There is a risk of serious injury.
Unbuckling seat belts1. Press the red button on the seat beltreceptacle and make sure the seat belt retracts fully into the retractor slot.
2. If it does not fully retract, guide the belt manually into the slot and make sure itdoes not hang loose.

Seat belt tensioners The vehicle is equipped with standard and electric seat belt tensioners that can help ten-sion the seat belt in a critical situation or colli-sion.
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 beltsin order to more effectively restrain the occu-pants.
Electric seat belt tensionersThe driver's and front passenger's seat beltsare equipped with electric seat belt tensioners. The seat belt tensioners interact and can be activated in conjunction with the City Safetyand Rear Collision Warning driver support sys-tems. In critical situations, such as if the vehi-cle brakes suddenly, begins to skid or runs offthe road (e.g if the vehicle rolls into a ditch,lifts off the ground or hits an obstacle in theroad), or if there is a risk of collision, the seatbelts can be pulled taut by the seat belt ten-sioner's electric motor. The electric seat belt tensioner helps to posi- tion the occupant more effectively in the seat,which reduces the risk of the occupant strik-ing the interior of the passenger compartment

The vehicle is equipped with a number of driver support systems that can provide thedriver with active or passive assistance in var-ious situations.
The systems can, for example, help the driver:
maintain a set speed
maintain a set time interval to the vehicle ahead
help prevent a collision by warning thedriver and applying the brakes
park the vehicle.
Some of the systems are standard and othersare options. This also varies from market tomarket.

Speed-dependent steering wheel resistance Speed-dependent power steering increases the steering wheel resistance in pace withthe vehicle's speed, which can help give thedriver an enhanced feeling of control and sta-bility.
Steering is stiffer on highways. When parking and at low speeds, it will be easier to movethe steering wheel.
NOTE
In rare situations, the power steering may become too hot andrequire temporary cooling – dur-ing such time the power steering
will work at reduced output and the steer-ing wheel may feel more difficult to move. The message
Power steering Assistance
temporarily reduced will be displayed
along with this symbol in the instrument panel.
While the power steering is working at reduced power, the driver support func-tions and systems with steering assistanceare not available.

Electronic Stability Control
The Electronic Stability Control (ESC 1
) func-
tion helps the driver avoid skidding and improves the vehicle's directional stability.
This symbol will be displayed in the instrument panel whenthe system is intervening. When the system has inter- vened to apply the brakes, apulsing sound may be heard
and the vehicle may accelerate more slowlythan expected when the accelerator pedal isdepressed.
The system consists of the following sub-func- tions:
Stability control 2
Spin control and active yaw control
Engine drag control
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.
