Automatic standby mode
Pilot Assist interacts with other systems, such asElectronic Stability Control. If any of these othersystems are not functioning properly, Pilot Assistwill automatically be deactivated.

WARNING
If this happens, the driver will be alerted by anaudible signal and a message in the instru-ment panel. The driver will have to adapt thevehicle's speed, apply the brakes when nec-essary and keep a safe distance to the vehicleahead.
Pilot Assist switches automatically to standbymode if:
•the camera cannot detect the traffic lane'sside marker lines
•the vehicle ahead is not within a reasonable(detectable) distance
•the driver's hands are not on the steeringwheel
•the driver unbuckles the seat belt
•engine speed (rpm) is too high/low
•the wheels lose traction
•brake temperature is too high
•the parking brake is set
•The camera lens/radar sensor is covered bye.g., wet snow or if heavy rain interferes withradar waves

Automatic braking with PilotAssist-1
The auto-hold brakes function as follows withPilot Assist.

Auto-hold brake function
In slow-moving, stop-and-go traffic or when stop-ped at a traffic light, driving will resume automati-cally if the vehicle is not stopped for more thanapprox. 3 seconds. If it takes more than3 seconds for the vehicle ahead to begin movingagain, Pilot Assist will go into standby mode andthe auto-hold brake function will activate.
–The driver will then have to reactivate PilotAssist in one of the following ways:
•Press the button on the left-sidesteering wheel keypad
•Press the accelerator pedal
>Pilot Assist will resume following the vehi-cle ahead (target vehicle) if it begins tomove within approx. 6 seconds.

NOTE
Pilot Assist can keep the vehicle at a stand-still for up to 5 minutes, after which the park-ing brake will be set and Pilot Assist will gointo standby mode.
The parking brake has to be released beforePilot Assist can be reactivated.
Deactivation of the auto-hold brake function
In certain situations, auto-hold will be deactivatedwhen the vehicle is at a standstill and Pilot Assistwill go into standby mode.
This means that the brakes will be released andthe vehicle can begin to roll.
The driver must actively apply the brakes to keepthe vehicle at a standstill.
This can occur in the following situations:
•the driver presses the brake pedal
•the parking brake is set
•the gear selector is moved to the P, N or Rpositions
•the driver puts Pilot Assist in standby mode

Automatically setting the parking brake
In certain situations, the parking brake is setautomatically to help keep the vehicle at a stand-still.
This occurs if:
•the driver unbuckles the seat belt or opensthe door
•Pilot Assist has kept the vehicle at a stand-still for more than approx. 5 minutes
•the engine is turned off
•the brakes overheat

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 radarsensor, the system may apply the brakes in yourvehicle suddenly or not at all.
Pilot Assist is designed to follow a vehicle aheadin 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 avoidancesystem. 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 slipperyconditions, when there is a great deal ofwater or slush on the road, during heavyrain or snow, in poor visibility, on windingroads or on highway on- or off-ramps.
NOTE
•Pilot Assist maintenance should only becarried 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.

In standby mode, the driver will have to regulatethe vehicle's speed and the distance to the vehi-cle ahead.
When Pilot Assist is in standby mode and yourvehicle comes too close to another vehicle, thedriver will be alerted by the Distance Alert func-tion.

Standby mode due to action by the driver
Pilot Assist is temporarily deactivated and put instandby mode if:
•the brakes are applied
•The gear selector is moved to N
•the turn signals are used for more than1 minute
•the vehicle is driven faster than the setspeed for more than 1 minute.
A temporary increase in speed, such as whenpassing another vehicle, does not affect the PilotAssist set speed. The vehicle will return to the setspeed when the accelerator pedal is released.
When the turn signals are used, Pilot Assist'ssteering function will be temporarily deactivated.When this is no longer the case, the steeringfunction will reactivate if the traffic lane's sidemarker lines can still be detected.

Automatic standby mode
Pilot Assist interacts with other systems, such asElectronic Stability Control. If any of these other
systems are not functioning properly, Pilot Assistwill automatically be deactivated.
WARNING
If this happens, the driver will be alerted by anaudible signal and a message in the instru-ment panel. The driver will have to adapt thevehicle's speed, apply the brakes when nec-essary and keep a safe distance to the vehicleahead.
Pilot Assist switches automatically to standbymode if:
•the vehicle's speed is below approx. 3 mph(5 km/h) and Pilot Assist cannot determine ifa vehicle ahead is a stationary vehicle or anobject.
•the vehicle's speed is below approx. 3 mph(5 km/h) and the vehicle ahead turns so thatPilot Assist no longer has a vehicle to follow(target vehicle).
•the driver's hands are not on the steeringwheel
•the driver's door is opened
•the driver unbuckles the seat belt
•engine speed (rpm) is too high/low
•the wheels lose traction
•brake temperature is too high
•the parking brake is set
•The camera lens/radar sensor is covered bye.g., wet snow or if heavy rain interferes withradar waves
