Setting an Adaptive Cruise Control time interval
ACC makes it possible to set various time inter- vals to the vehicle ahead.
Different time intervals to the vehicle ahead can be selectedand are shown in the instru-ment panel as 1–5 horizontalbars. The greater the number ofbars, the longer the time inter-val. One bar between the vehi-
cles represents a time interval of approximately1 second; 5 bars is approximately 3 seconds. The same symbol appears if Distance Alert is activated.
• If the symbol shows two vehicle's, ACC is actively following the vehicle ahead.
• If only one vehicle is displayed, ACC is
not
actively following another vehicle.

In order to follow the vehicle ahead as smoothly as possible, ACC allows the time interval to varyconsiderably in certain situations. At low speeds,when the distance to the vehicle ahead is short,ACC increases the time interval slightly. • If ACC does not seem to react when it is put in active mode, this may be because the set

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 is designed to regulate speed smoothly but in situations calling for fast braking,the driver must apply the brakes. This applies tosituations where there are considerable differen-ces in speed or if the vehicle ahead brakes sud-denly. Due to the limitations of the camera andradar sensor, the system may apply the brakes inyour vehicle suddenly or not at all. The default speed for Pilot Assist is preset toapprox. 30 mph (50 km/h) and cannot bechanged. If the vehicle ahead increases speed toover 30 mph (50 km/h) and pulls away from yourvehicle, Pilot Assist will go into standby mode.
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.
WARNING
•Pilot Assist does not react to people or animals, or small vehicles such as bicy-cles and motorcycles. It also does notreact to low trailers, slow moving, parkedor approaching vehicles, or stationaryobjects.
• 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.

Prerequisites
The prerequisites for activating Pilot Assist are:
• The vehicle ahead must be within a reasona- ble (detectable) distance
• The camera must be able to clearly detectthe traffic lane's side marker lines
• The vehicle's speed must be under approx.30 mph (50 km/h).
A WHITE symbol indicates that Pilot Assist has been selected. In other cases, the WHITE arrow pointing to the right indi-cates that the system is availa-ble.
A YELLOW symbol with a flashing WHITE arrow indicates that the system is about to shift intostandby mode. With ACC in standby mode:1.Tap ▶ (4).
> The symbol will be displayed and Pilot Assist will go into standby mode.
2. Press the
button (1) on the left-side
steering wheel keypad.
> Pilot Assist will go into active mode.
WARNING
• Pilot Assist is not a collision avoidance system. The driver is always responsiblefor applying the brakes if the system doesnot detect another vehicle.
• 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.
• Pilot Assist uses the vehicle's cameraand radar sensor, which have limitations.
Pilot Assist may deactivate or not function optimally if:

•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.
• if there are edges or other lines on ornear the lane, e.g., curbs, cracks, repairedareas, sharp shadows, etc.
• the lane is narrow or winding.
• the weather conditions (rain, snow, fog,slush, poor visibility, backlighting, etc).
The driver should also be aware that Pilot Assist has the following limitations: • High curbs, barriers and temporary obsta- cles (cones, barriers etc) may not bedetected or could be detected incorrectlyas side marker lines, which may create arisk of collision. The driver must ensure asafe distance to these obstacles.
• The camera or radar sensor may not beable to detect objects if there are pot-holes or if there are stationary objectspartially or completely blocking the road.
• Pilot Assist does not "see" pedestrians,animals, etc.
• Pilot Assist's steering capacity is limitedand may not always be able to help thedriver keep the vehicle in the lane.Hands on the steering wheel
Pilot Assist only functions when the driver's hands are on the steering wheel
, which is con-
tinuously monitored by the system. If this is notthe case, the driver will be alerted by a text mes-sage in the instrument panel. If the driver's handsare not returned to the steering wheel, an audiblesignal will sound. If the driver does not return his/her hands to the steering wheel after the audible signal, PilotAssist will go into standby mode and must be reactivated by pressing

STARTING AND DRIVING

Available drive modes
HYBRID
This is the default mode. The vehicle normally starts in
Hybrid mode 4
. The
engine management system uses both the elec- tric motor and gasoline engine (separately or intandem) and calculates the optimal levels of per-formance, fuel consumption and comfort. Athigher speeds, ground clearance is reducedautomatically to help reduce wind resistance. The amount of driving done using only the elec- tric motor in
Hybrid mode is determined by the
hybrid battery's charge level and the need for heating/cooling in the passenger compartment. If sufficient electrical energy is available, only the electric motor will be activated when the driverpresses the accelerator pedal up to a certainlevel. Above this level, the gasoline engine willstart.The instrument panel gauge when both the electric motor and gasoline engine are being used
The long needle in the gauge indicates the amount of energy that the vehicle is currentlyusing. The short white line between the "light-ning" and "oil drop" symbols indicates theamount of energy available. See also the article"General information about the XC90 T8 TwinEngine Plug-in Hybrid" for additional information. The gasoline engine starts when the response required when the driver presses the acceleratorpedal cannot be provided by the electric motoralone. The gauge also indicates when the battery is being recharged (regenerated) during light brak-ing. See the article "Brakes" for additional infor-mation. When the hybrid battery's charge level is low, thegasoline engine will start more often to help con-serve electrical energy. Charge the battery withthe charging cable as soon as possible or switch to the
Save drive mode.
PURE
This mode activates the electric motor only with as low energy consumption as possible and thelowest possible carbon dioxide emissions. Ground clearance will be lowered to help reduce wind resistance and certain climate system func-tions will be reduced.
Pure mode is available when the hybrid battery is
sufficiently charged. If the level gets too low, the gasoline engine will start. The gasoline engine will also start: • If the vehicle's speed goes above approx. 75 mph (125 km/h)
• If the driver wants more response than theelectric motor alone can provide
• If factors such as cold weather, etc., affectthe system or components
To restart the climate system functions that have been reduced in the mode, press the,
AUTO or
defroster buttons.
4 Unless the vehicle was switched off in Off Road mode. If so, it will restart in Off Road mode.
