Changing target vehicles and automatic braking with Pilot Assist
At certain speeds, Pilot Assist can change target vehicles and automatically apply the brakes.
Changing target vehicles
If the target vehicle turns suddenly, there may be a sta- tionary vehicle ahead
When Pilot Assist is actively following another vehicle at speeds under 20 mph (30 km/h) and
changes targets from a moving vehicle to a sta- tionary one, the system will brake for the station-ary vehicle.
WARNING
If Pilot Assist changes targets from a moving vehicle to a stationary one at speeds above
20 mph (30 km/h), the system will not react
to the stationary vehicle and will accelerate to the previously set speed. The driver must actively apply the brakes to slow/stop the vehicle.
Automatic standby mode when changing targets
Pilot Assist disengages and goes into standby mode if:
• your vehicle's speed goes below approx.3 mph (5 km/h) and Pilot Assist cannotdetermine if the target object is a stationaryvehicle or some other type of object such asa speed bump, etc
• the vehicle's speed goes below approx.3 mph (5 km/h) and the vehicle aheadchanges lanes or turns so that Pilot Assistno longer has a target vehicle to follow
Auto-hold brake functionIn 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 Pilot Assist in one of the following ways:
• Press the
button on the left-side
steering wheel keypad
• Press the accelerator pedal
> Pilot Assist will resume following the vehi- cle ahead (target vehicle) if it begins to move 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 before Pilot Assist can be reactivated.
Deactivation of the auto-hold brake function
In certain situations, auto-hold will be deactivated when the vehicle is at a standstill and Pilot Assistwill go into standby mode. This means that the brakes will be released and the vehicle can begin to roll. The driver must actively apply the brakes to keep the 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 R
positions
• the driver puts Pilot Assist in standby mode
Automatically setting the parking brakeIn certain situations, the parking brake is set automatically to help keep the vehicle at a stand-still. This occurs if Pilot Assist keeps the vehicle at a standstill with the brakes and:
• 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 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.
• the lane is at the top of a hill, on anuneven road surface or over a bump.
•bad 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.
The driver can always take action to override PilotAssist.
Steep roads and/or heavy loadsPilot Assist is primarily intended for use on rela-tively level roads. The function may not be able tomaintain the correct time interval to the vehicleahead on when driving down steep hills. Thedriver should be attentive and prepared to applythe brakes in these situations. Do not use Pilot Assist when the vehicle is trans-porting a heavy load or if it is towing a trailer.
Additional information
•
The Off Road drive mode cannot be
selected if Pilot Assist is activated.
• Pilot Assist uses the vehicle's camera and radar sensor, which have certain general limi-tations. See the articles "Camera limitations"and "Radar sensor limitations" for additionalinformation.

Driving lane assistance provides vibrations in the steer- ing wheel7
.
Depending on the settings used, Lane Keeping Aid functions in different ways:
• Assistance type
Steering8
is activated: when
the vehicle approaches a traffic lane marker line, LKA will provide active steering assis-tance to help steer it back into the lane.
• Assistance type
Warning8
is activated: if the
vehicle is moving out of its traffic lane, an audible signal and/or vibrations in the steer-ing wheel will be provided.
NOTE
If the turn signal is used, Lane Keeping Aid will not provide an alert or steering assis-
tance.
WARNING
Lane Keeping Aid is only intended to assist the driver and does not function in all driving,weather, traffic or road conditions. As the driver, you have full responsibility for operating the vehicle in a safe manner.
Steering assistanceIn order for LKA's steering assistance to function, the driver's hands must be on the steering wheel,which the system monitors continuously.
If the driver's hands are not onthe steering wheel, this symbolwill illuminate in the instrumentpanel and the following mes-sage will be displayed:
•Lane Keeping Aid – Apply steering
If the driver does not begin to steer the vehicle, the symbol will illuminate again, an audible signal will sound and the following message will be dis-played:
•
Lane Keeping Aid – Standby until
steering applied
If the driver still does not begin to steer the vehi- cle, LKA will go into standby mode. The functionwill not become available again until the driveractively steers the vehicle
Traffic lane assistance does not react
The traffic lane assistance system does not intervene in sharp curves
In certain cases, such as during active driving or if the turn signal is used, the traffic lane system will not react if the vehicle crosses a lane marker
line.
7 The level of vibrations varies; the farther the vehicle is over a lane marker line, the greater the number of vibrations:
8 See "Type of assistance" in the article "Activating/deactivating Lane Keeping Aid".

Backing up
Location of the rear Park Assist Camera (generic illus- tration)
The rear camera shows a wide area behind the vehicle and on certain models, part of the bumperand the trailer hitch (if installed) will be visible. Some objects on the screen may appear to “lean” slightly, which is normal.
WARNING
People/objects/obstructions displayed on the center console screen may be closer to thevehicle than they appear.
Front camera
Location of the front Park Assist Camera (generic illus- tration)
The front camera is located behind the grill and can be useful when driving off in areas with lim-ited visibility (hedges, bushes, etc). It is active atspeeds up to approx. 16 mph (25 km/h) and isautomatically turned off when the vehicleexceeds this speed. However, if the vehicle's speed does not exceed 30 mph (50 km/h) and its speed goes under14 mph (22 km/h) within 60 seconds after thecamera has been switched off, the front camerawill reactivate.
NOTE
The front camera will only reactivate automati- cally if Auto Camera Reverse Activation
has been selected in SettingsMy CarPark Assist.

Driving on wet or salted roadsProlonged driving on wet or salted roads can affect brake function and increase stopping dis-tance. Be sure to keep a safe distance to thevehicle ahead when driving under these condi-tions.
Brake pad inspection
On vehicles equipped with a jack *, the condition
of the brake pads can be checked by raising thevehicle and performing a visual inspection of thebrake pads.
WARNING
• If the vehicle has been driven immediately prior to a brake pad inspection, the wheelhub, brake components, etc., will be veryhot. Allow time for these components tocool before carrying out the inspection.
• Apply the parking brake and put the gear selector in the Park (
P) position.
• Block the wheels standing on the ground, use rigid wooden blocks or large stones.
WARNING
•
Use the jack intended for the vehicle when changing a tire. For any other job,use stands to support the vehicle.
• The jack should be kept well-greased andclean, and should not be damaged.
• Be sure the jack is on a firm, level, non-slippery surface.
• No objects should be placed between thebase of jack and the ground, or betweenthe jack and the attachment bar on thevehicle.
• The jack must correctly engage the jackattachment.
• Never allow any part of your body to beextended under a vehicle supported by ajack.

Brake assist system The Brake Assist System (BAS) increases brak- ing force, thereby helping reduce braking dis-tance.
The system monitors the driver's braking habits and increases braking force when necessary.Brake force can be increased up to the point atwhich the ABS system is activated. The functionis deactivated when pressure on the brake pedaldecreases.

Braking effect after a collision
In certain types of collisions, the vehicle's brakes are applied to help prevent or mitigate a secon-dary collision.
Maintaining control of the vehicle after a collision may be difficult. To help avoid or mitigate theeffect of a secondary collision, the brakes areapplied automatically to help bring the vehicle toa stop. The brake lights and hazard warning flashers will be activated and the flashers will remain on afterthe vehicle has come to a standstill. The parkingbrake will then be applied automatically. In a situation where stopping the vehicle may not be desirable, the driver can override this systemby pressing the accelerator pedal. This feature can only function if the brake system is intact after the collision.

• Consider your destination. If you will be driv-ing through an area where snow or ice arelikely to occur, consider using snow tires.
Driving economically
Better driving economy can be obtained by thinking ahead, avoiding rapid starts and stopsand adjusting the speed of your vehicle to imme-diate traffic conditions.
Economical driving conserves natural resources
Observe the following rules: • Bring the engine to normal operating tem- perature as soon as possible by driving witha light foot on the accelerator pedal for thefirst few minutes of operation. A cold engineuses more fuel and is subject to increasedwear.
• Whenever possible, avoid using the vehiclefor driving short distances. This does notallow the engine to reach normal operatingtemperature.
• Drive carefully and avoid rapid accelerationand hard braking.
• Use the transmission's Drive (
D) position as
often as possible and avoid using kick-down.
• Using the engine's Eco function can helpimprove fuel economy.
• Do not exceed posted speed limits.
• Avoid carrying unnecessary items (extra load)in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when the tires are cold). •
Use tires recommended by Volvo for yourvehicle.
• Remove snow tires when threat of snow orice has ended.
• Note that roof racks, ski racks, etc, increaseair resistance and also fuel consumption.
• At highway driving speeds, fuel consumptionwill be lower with the air conditioning on andthe windows closed than with the air condi-tioning off and the windows open.
• Using the onboard trip computer's fuel con-sumption modes can help you learn how todrive more economically.
Other factors that decrease gas mileage are:
• Dirty air cleaner
• Dirty engine oil and clogged oil filter
• Dragging brakes
• Incorrect front end alignment
Some of the above mentioned items and othersare checked at the standard maintenance inter-vals.
Handling and roadholding
• Vehicle load, tire design and inflation pres-sure all affect vehicle handling. Therefore,check that the tires are inflated to the rec-ommended pressure according to the vehicleload. Loads should be distributed so that
