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.

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. 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 belt on your own. Volvo recommends contactingan authorized Volvo workshop. If the seat belt has been exposed to extreme forces, 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.

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 isshown in the instrument panel varies dependingon 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. The instrument panel is available in two versions: 12"
* and 8".WARNING
If the instrument panel is not functioning properly, information about brakes, airbags orother safety-related systems may not be dis-played. The driver will then not be able tocheck the status of the vehicle systems orreceive relevant warnings and information.
WARNING
If the instrument panel turns off, does not activate when the ignition is switched on, orpart/all of the panel cannot be read, do notdrive the vehicle. Consult a workshop immedi-ately. Volvo recommends an authorized Volvoworkshop.

Press the button for On/Off. The
symbol in
the instrument panel illuminates when the rear fog light is on. The rear fog light turns off automatically when:
• the start knob is turned clockwise to turn off the ignition or when the lighting ring is turned to the
position.
• the lighting ring is in the
position and
the front fog lights are turned off.

Emergency brake lights
The emergency brake lights are activated to warn following vehicles of hard braking. This function causes an additional taillight on each side of the vehicle to illuminate.
The emergency brake lights are activated in the event of hard braking or if the ABS system isactivated and the vehicle is traveling at a highspeed. After the driver decelerates to a low speed and then releases the brake, the brake lights resumetheir normal brightness.

DRIVER SUPPORT
* Option/accessory.

Driver support systems
The vehicle is equipped with a number of driver support systems that can provide the driver withactive or passive assistance in various situations.
The system can, for example, help the driver maintain a set speed or a set time interval to thevehicle ahead, help prevent a collision by warningthe driver and applying the brakes, or assist thedriver while parking. Some of the systems are standard and others are options. This also varies from market to market.

Speed-dependent steering wheelresistance
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 tomove 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 willwork at reduced output and the steeringwheel may feel more difficult to move. In parallel with the temporarily reduced steer- ing assistance, the driver display shows amessage as well as a STEERING WHEELsymbol.
