IntelliSafe - driver support
IntelliSafe is Volvo Cars' philosophy regarding vehicle safety. IntelliSafe consists of a number ofsystems, both standard and optional, that aredesigned to help make driving safer, preventaccidents and protect passengers and otherroad users.
SupportIntelliSafe includes driver support functions such as Adaptive cruise control * which helps the driver
to maintain an even speed combined with a pre- selected time interval to the vehicle ahead. Pilot Assist 4
helps the driver keep the vehicle in
the current traffic lane by providing steering assistance and maintaining an even speed and aset time interval to the vehicle ahead. Park Assist Pilot * helps the driver pull into and
out of parking spaces. Other examples of systems that can help the driver are the Active main beam, Cross Traffic Alert (CTA) * and Blind Spot Information (BLIS) *
systems.
PreventionCity Safety is a function intended to help prevent accidents. The function can help prevent or miti-gate a collision with pedestrians, cyclists, largeanimals or other vehicles. Light, sound and pulsa-tions in the brake pedal are provided to alert of a

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.

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.

DRIVER SUPPORT
* Option/accessory.271
WARNING
While the power steering is working at reduced power, the driver support functionswith steering assistance are not available. In such a situation, the driver display shows the
Power steering failure or Power

message, combined with a STEERING WHEEL symbol.
Changing the level of steering wheel resistance *
To change the level of steering wheel resistance, see the description of the INDIVIDUAL optionunder "Available drive modes" in the "Drivemodes" section. On models not equipped with drive mode con- trols and the INDIVIDUAL option, steering wheelresistance can instead be set in the center dis-play's Top view under:

Stability system Roll StabilityControl
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 vehiclebegins to skid.
The RSC system monitors the lateral angle at which the vehicle is leaning and registers anychanges. Using this information, the system cal-culates the likelihood of a rollover. If there is animminent risk of a rollover, Electronic StabilityControl is activated, engine torque is reduced andbrakes are applied to one or more of the wheelsuntil the vehicle has regained stability.

Passing assistance with AdaptiveCruise Control Adaptive Cruise Control (ACC 51
) can assist the
driver when passing other vehicles.
How passing assistance worksWhen ACC is following another vehicle and you indicate that you intend to pass that vehicle by using the turn signal 52
, Adaptive Cruise Control
will begin accelerating toward the vehicle ahead before your vehicle has moved into the passing
lane. The function will then delay a speed reduction to avoid early braking as your vehicle approaches aslower-moving vehicle. The function remains active until your vehicle has passed the other vehicle.
WARNING
Please note that this function can be acti- vated in more situations than just passinganother vehicle, such as when a direction indi-cator is used to indicate a lane change orbefore exiting to another road – the vehiclewill then briefly accelerate.

Requirements for passing assistanceIn order to activate passing assistance:
• your vehicle must be following a vehicle ahead (target vehicle)
• your vehicle's
current speed must be
at least 70 km/h (43 mph)
• the set speed
for ACC must be high
enough to safely pass another vehicle.
Starting parking assistanceTo start passing assistance:
–Turn on the left turn signal.

Limitations of passing assistancewith Adaptive Cruise Control
Passing assistance functionality may be reduced in certain situations.
WARNING
The driver should be aware that if conditions suddenly change when using Parking Assis-tance, the function may implement an unde-sired acceleration in certain conditions. Some situations should be avoided, e.g. if: • the vehicle is approaching an exit in the same direction as passing would normallyoccur
• the vehicle ahead slows before your vehi-cle has had time to switch to the passinglane
• traffic in the passing lane slows down
• a vehicle for right-hand traffic is driven ina country with left-hand traffic (or viceversa).
Situations of this type can be avoided by tempo- rarily putting ACC 53
in standby mode.

Switching target vehicles withAdaptive Cruise Control
At certain speeds, models with automatic trans- missions and Adaptive Cruise Control (ACC 54
)
can switch target vehicles.
Switching target vehicles
If the target vehicle ahead turns suddenly, there may be stationary traffic ahead.
When Adaptive Cruise Control is actively follow- ing another vehicle at speeds under 30 km/h
(20 mph) and switches targets from a moving vehicle to a stationary vehicle, Adaptive CruiseControl will brake for the stationary vehicle.
WARNING
When Adaptive Cruise Control follows another vehicle at speeds over approx. 30 km/h
(20 mph) and changes target vehicle – from a moving vehicle to a stationary one – Adaptive Cruise Control will ignore the stationary vehi-
cle and instead accelerate to the stored speed. • The driver must then intervene and apply the brakes.
Automatic standby mode when switching
targets
Adaptive Cruise Control will be disabled and go into standby mode:
• if your vehicle's speed goes below 5 km/h(3 mph) and Adaptive Cruise Control cannotdetermine if the target object is a stationaryvehicle or another object, e.g. a speed bump.
• if your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns so thatAdaptive Cruise Control no longer has a vehi-cle to follow.
