IntelliSafe
—driver support
IntelliSafe is Volvo's philosophy regarding vehi- cle safety. It encompasses a number of systems,both standard and optional, that are designed tohelp make driving and traveling in a Volvo safer.
SupportSystems that help make driving safer are an inte- gral part of IntelliSafe. These include optional features such as Adaptive Cruise Control * that
helps maintain a set distance to a vehicle ahead,Park Assist Pilot *, which assists in parking the
vehicle, Cross Traffic Alert *, Blind Spot
Information *, etc.
Accident preventionSystems such as City Safety are designed to automatically apply the brakes in situations inwhich the driver does not have time to react. Lane Keeping Aid * alerts the driver if the vehicle
inadvertently crosses a lane's/road's side marker line.
ProtectionThe vehicle is equipped with e.g., seat belt pre-tensioners that pull the seat belts taut in criticalsituations when there is a collision risk andnumerous airbags designed to help provide cush-ioning if certain types of collisions should occur.

Distance Alert * limitations
Distance Alert uses the same radar sensor as Adaptive Cruise Control * and has several limita-
tions.
WARNING
• The radar sensor has a limited field of vision. In some situations it may detect avehicle later than expected or not detectother vehicles at all.
• The radar sensor cannot cover all drivingsituations and traffic, weather and roadconditions.
• The driver is responsible for maintaining asafe distance and speed and must inter-vene if the various driver support systemsdo not maintain a suitable speed or suita-ble distance to the vehicle ahead.
• Maintenance of radar sensor componentsmay only be performed by a trained andqualified Volvo technician.
• Strong sunlight, reflections from the roadsurface, strong lighting contrasts or usingsunglasses may make the warning light inthe windshield difficult to see.
WARNING
•
Poor weather or winding roads can affect the radar sensor's capacity to detect vehi-cles ahead.
• A vehicle's size (e.g., a motorcycle) canalso affect the radar sensor's capacity todetect another vehicle. This may result inthe warning light illuminating at a shorterdistance than the one that has been setor not illuminating at all.
• High speeds may also result in the warn-ing light illuminating at a shorter distancethan the one that has been set due tolimitations in the radar sensor's range.
For additional information, see also the article"Radar sensor limitations."

Adaptive Cruise Control (ACC) *
ACC is an optional system designed to assist the driver by maintaining a set speed or a settime interval to the vehicle ahead.
ACC helps provide more relaxed driving on long trips on highways or other major roads in a rela-tively even flow of traffic.
The camera and radar sensor monitor the distance to the vehicle ahead (generic illustration - certain detailsmay vary from model to model)
The driver sets that desired speed and time inter- val to the vehicle ahead. When the camera andradar sensor detects a slower moving vehicleahead, your vehicle's speed is automaticallyadapted. When there are no longer slower mov-ing vehicles ahead, your vehicle will accelerate toresume the set speed. ACC is designed to follow a vehicle ahead in the same lane and maintain a time interval to that

Passing Assistance with Adaptive Cruise Control or Pilot Assist
ACC or Pilot Assist can assist the driver when passing other vehicles.
How passing assistance worksWhen ACC or Pilot Assist is following another vehicle and the driver indicates that he/she isabout to pass that vehicle by using the left turnsignal, ACC or Pilot Assist will begin acceleratingtoward the vehicle ahead before your vehicle hasmoved into the passing lane. The function will then delay a speed reduction to avoid early braking as your vehicle approachesthe slower-moving vehicle. The function is active until your vehicle has passed the other vehicle.
WARNING
Be aware that this function may be activated in situations other than when passing a vehi-cle, such as if the turn signal is used to indi-cate a lane change or to indicate a turn. Thevehicle will accelerate briefly.
Using passing assistanceTo activate passing assistance:
• Your vehicle (ACC or Pilot Assist) must be following another vehicle (the target vehicle).
• Current speed must be at least approx.45 mph (70 km/h ). •
The speed set for ACC or Pilot Assist mustbe high enough to safely pass the vehicleahead.
Starting passing assistanceTo start a passing assistance sequence:
• Activate the left turn signal.
Passing assistance limitations
WARNING
The driver should be prepared for sudden changes when passing assistance is used. Incertain cases, there may be undesired accel-eration. Certain situations should be avoided, such as: • If the vehicle is approaching an exit to the left or a left turn.
• If the vehicle ahead slows down beforeyour vehicle has moved into the passinglane.
• Traffic in the passing lane slows down.
Passing assistance in these situations can bedeactivated by putting ACC or Pilot Assist instandby mode.

Changing target vehicles and automatic braking with AdaptiveCruise Control (ACC)
At certain speeds, Adaptive Cruise Control can change target vehicles and automatically applythe brakes.
Changing target vehicles
If the target vehicle turns suddenly, there may be a sta- tionary vehicle ahead
When ACC is actively following another vehicle at speeds under 20 mph (30 km/h) and changes
targets from a moving vehicle to a stationary one, the system will brake for the stationary vehicle.

Pilot Assist*
The Pilot Assist feature helps keep the vehicle in its current traffic lane by providing steeringassistance and maintaining an even speed and aset time interval to the vehicle ahead.
FunctionPilot Assist helps provide more relaxed driving on long trips on highways or other major roads in aneven flow of traffic.
Function overview (generic illustration)
Windshield module containing the camera/ radar sensor
Monitoring distance
Monitoring side marker lines
The driver sets the desired time interval to the vehicle ahead. Pilot Assist monitors that vehicleand the traffic lane's side market lines using the camera and radar sensor mounted in the upper,center section of the windshield. It helps maintainthe set time interval by automatically adjustingspeed and by providing steering assistance tohelp keep your vehicle in the lane. Pilot Assist's steering assistance is based on monitoring the direction of the vehicle ahead andthe traffic lane's side marker lines. The driver canalways override Pilot Assist and steer the vehicleto e.g., change lanes, etc. If the camera and radar sensor cannot detect the lane's side marker lines, Pilot Assist will tempo-rarily switch off the steering assistance until thelane's side marker lines become visible again andcan be detected. However, the function's speedand distance monitoring will continue to be acti-vated.
WARNING
Pilot Assist's steering assistance may switch on or off without warning.
The color of the steering wheel symbol indicates the currentstatus of the steering assis-tance function: GREEN: steering assistance is active
GRAY (as in the illustration): steering assistanceis deactivated
WARNING
• Pilot Assist is designed to be a supple- mentary driving aid and cannot cover alldriving situations, traffic, weather and/orroad conditions.
• The driver should be familiar with all ofthe information in this article regardingPilot Assist, including its limitations.
• Pilot Assist is not intended to replace thedriver's attention and judgement.
• Pilot Assist must only be used wherethere are clearly visible traffic lane sidemarker lines on both sides of the currenttraffic lane. In other circumstances thereis an increased risk of collision with sur-rounding obstacles that are not detectedby the system.
• The driver is always responsible for steer-ing the vehicle and maintaining a suitablespeed and distance to the vehicle aheadand must intervene if necessary, even ifPilot Assist is being used.
Pilot Assist attempts to regulate speed smoothlybut in situations calling for fast braking, the drivermust apply the brakes. This applies to situationswhere there are considerable differences inspeed or if the vehicle ahead brakes suddenly.Due to the limitations of the camera and radar

DRIVER SUPPORT
284sensor, the system may apply the brakes in your vehicle suddenly or not at all. Pilot Assist is designed to follow a vehicle ahead in the same traffic lane at a preset time intervalset by the driver. If the radar sensor does notdetect a vehicle ahead, the vehicle will insteadmaintain the speed set by the driver. This will alsobe the case if a vehicle ahead accelerates andexceeds the set speed.
• Pilot Assist can follow another vehicle from astandstill up to a speed of approx. 125 mph(200 km/h)
• Pilot Assist can provide steering assistancefrom very low speeds up to approx. 87 mph(140 km/h).
Never exceed posted speed limits.
WARNING
• Pilot Assist is not a collision avoidance system. The driver must react if the sys-tem does not detect another vehicle.
• Pilot Assist does not react to people, ani-mals, stationary objects, small vehicles(such as bicycles and motorcycles), lowtrailers and slow moving, parked orapproaching vehicles.
• Do not use Pilot Assist in demandingdriving conditions such as city driving orother heavy traffic situations, in areas withintersections, in slippery conditions, whenthere is a great deal of water or slush onthe road, during heavy rain or snow, inpoor visibility, on winding roads, on high-way on- or off-ramps or if the vehicle istowing a trailer, boat, etc.
NOTE
•Pilot Assist maintenance should only be carried out by a trained and qualifiedVolvo service technician.
• Pilot Assist regulates your vehicle'sspeed using the accelerator pedal andthe brakes. Please be aware that theremay be a faint sound from the brakeswhen the system is using them.

steering wheel keypad.
> Pilot Assist will go into active mode and the current speed will be stored and dis- played in the center of the speedometer. or
If Adaptive Cruise Control has been started:
–Tap ▶ (6).
> Pilot Assist will start.
Pilot Assist's steering assis- tance is only active when thesteering wheel symbol (2)changes from GRAY toGREEN.
And Pilot Assist will only regulate the time inter- val to the vehicle ahead when a vehicle symbol(1) is displayed above the steering wheel. At the same time, a speedinterval will be marked. The higher speed is the one stored by the driver and thelower one is the speed of thevehicle ahead (target vehicle).WARNING
Pilot Assist is not a collision avoidance sys- tem. The driver is always responsible forsteering or applying the brakes if the systemdoes not detect another vehicle. Do not use Pilot Assist in demanding driving conditions such as city driving or other heavytraffic situations, in slippery conditions, whenthere is a great deal of water or slush on theroad, during heavy rain or snow, in poor visibil-ity, on winding roads or on highway on- or off-ramps. In certain situations, it may be difficult for Pilot Assist to assist the driver correctly or to deac-tivate automatically. In such cases, it is advisa-ble not to use Pilot Assist. Examples of suchsituations may be:
• the lane's side market lines are missing, badly faded or cross each other.
• the division of lanes is not clear, e.g.,when a line divides or merges withanother, at exits or if there are many roadsigns/markers.
• there are edges or other lines on or nearthe lane, e.g., curbs, cracks, repairedareas, sharp shadows, etc.
• the lane is narrow or winding.
