2019 VOLVO S60 TWIN ENGINE brake sensor

DRIVER SUPPORT
* Option/accessory.327
In a diagonal parking space, CTA may be completely"blind" on one side of your vehicle.
CTA's blind zone.
CTA's field of vision.
However, as you back your vehicle slowly out of aparking space, CTA's field of vision changes inrelation to the obstructing vehicle/object and itsblind zone is reduced.

Examples of further limitations
The auto brake sub-function only detectsvehicles in motion and may therefore not
"see" and brake for e.g. stationary obstacles,a cyclists or a pedestrian.
Dirt, ice and snow covering the sensors mayreduce functionality and prevent the systemfrom providing warnings.
CTA is automatically deactivated if a trailer,bicycle holder or similar is connected to thevehicle's electrical system.
For CTA to function optimally, bicycle hold-ers, luggage racks or similar should not bemounted on the vehicle's towbar.
NOTE
The function uses the vehicle's camera andradar sensor, which has certain general limita-tions.

Park Assist front, rear and sides*
Park Assist behaves differently depending onwhich part of the vehicle is approaching anobstacle.

Front camera
The warning signal has a continuous tone when theobstacle is less than approx. 30 cm (1 ft) from the vehi-cle.
The Parking Assist system's front sensors areautomatically activated when the engine isstarted. They are active at speeds below 10 km/h(6 mph).
The distance monitored extends approx. 80 cm(2.5 ft) in front of the vehicle.
NOTE
The Parking Assist system is deactivatedwhen the parking brake is used or when P isselected on vehicles with automatic transmis-sion.

CAUTION
When installing auxiliary lights: Make surethese do not obscure the sensors – the auxili-ary lights could be perceived as an obstacle.

Back
The warning signal has a continuous tone when theobstacle is less than approx. 30 cm (1 ft) from the vehi-cle.
The rear sensors will be activated if the vehiclebegins rolling backward or if reverse gear isengaged.

Park Assist limitations
Park Assist may not be able to detect all condi-tions in all situations and functionality may there-fore be limited in certain cases.
The driver should be aware of the following limi-tations for Park Assist:

WARNING
Be extra cautious whenreversing if this symbol isshown when a trailer, bikecarrier or similar is attachedand electrically connectedto the vehicle.
The symbol indicates thatthe rear parking assist sensors are deacti-vated and will not warn of any obstacles.
CAUTION
Objects such as chains, thin and glossy polesor low obstacles may end up in the "signalshadow" and then go temporarily undetectedby the sensors – the pulsating tone may thenunexpectedly stop instead of becoming aconstant tone as expected.
The sensors cannot detect high objects, suchas protruding ramps.
In such situations, pay extra attention andmaneuver/drive the vehicle very slowly orstop the current parking maneuver –there may be a high risk of damage tothe vehicle or other objects since infor-mation from the sensors is not alwaysreliable in such situations.

CAUTION
In some circumstances, the Park Assist Sys-tem may produce false warnings due to exter-nal sound sources with the same ultrasonicfrequencies as those the system works with.
Examples of such sources are horns, wet tireson asphalt, pneumatic brakes, exhaust noisefrom motorcycles, etc.
NOTE
When a trailer hitch is configured with thevehicle electrical system, the trailer hitch pro-trusion is included when the function meas-ures the distance to objects behind the vehi-cle.

Park Assist Pilot*
Park Assist Pilot (PAP91) can help the drivermaneuver the vehicle when parking. The functioncan also assist with steering when pulling outfrom a parallel parking space.
The function first checkswhether there is sufficientspace and then helps the driversteer the vehicle into the space.
The center display uses sym-bols, graphics and messages toinform the driver of what steps need to be takenand when.

WARNING
The parking sensors have dead/blindspots where objects cannot be detected.
Pay particular attention to people andanimals near the vehicle.
Bear in mind that the front end of thevehicle may swing out towards oncomingtraffic during the parking maneuver.
WARNING
The function is supplementary driver sup-port intended to facilitate driving and helpmake it safer – it cannot handle all situa-tions in all traffic, weather and road condi-tions.
The driver is advised to read all sectionsin the Owner's Manual about this functionto learn of its limitations, which the drivermust be aware of before using the func-tion.
Driver support functions are not a substi-tute for the driver's attention and judg-ment. The driver is always responsible forensuring the vehicle is driven in a safemanner, at the appropriate speed, with anappropriate distance to other vehicles,and in accordance with current trafficrules and regulations.
NOTE
The PAP function measures the space andsteers the vehicle – the driver's role is to:
keep close watch of the area around thevehicle
follow the instructions on the center dis-play
change gears (reverse/forward) – a"ping" sound indicates when the drivershould change gears
regulate and maintain a safe speed
apply the brakes and stop.

Positioning the vehicle in the parking space
Parallel parking overview.
Perpendicular parking overview.
To do so:
1.Move the gear selector to the gear instructedby the system. Wait until the steering wheelturns and then drive slowly forward.
2. Be prepared to stop the vehicle wheninstructed to do so by a graphic and mes-sage in the center display.
3. Engage reverse gear and back up slowly.
4. Be prepared to apply the brakes wheninstructed to do so by a graphic and mes-sage in the center display.
The function will switch off automatically and agraphic and message will appear to indicate thatparking has been completed. Adjustments canalways be made be the driver afterward. Only thedriver can determine when the vehicle is correctlyparked.

CAUTION
The warning distance is shorter when the
sensors are used by Park Assist Pilot (PAP94)compared to when they are used by the Park-ing Assist system.

Leaving a parallel parking space
with Park Assist Pilot*
The Park Out function can help the driver to pullout of a parking space when the vehicle is paral-lel-parked.
NOTE
Leaving a parking space with the Park Outfunction should only be used in connectionwith parallel parking – it does not work forperpendicular parking.
The Park Out function is acti-vated in the center display'sFunction view or in Cameraview.
To do so:
1.Tap Park Out in Function view or in Cameraview.
2.Move the gear selector to the suitable posi-tion (e.g. D or R) for the direction in whichyou will be pulling out of the parking space.

The driver should be aware of the following limi-tations for Park Assist Pilot:

The parking sequence is cancelled
A parking sequence will be cancelled if:
The driver moves the steering wheel
The vehicle's speed exceeds 7 km/h(4 mph)
The driver taps Cancel in the center display
When the anti-lock brakes or the Electronicstability control are engaged - e.g. when awheel loses grip on a slippery road
When speed-dependent power steeringwheel resistance is working at reducedpower – e.g. during cooling due to overheat-ing.
A message in the center display will explain whythe parking sequence was cancelled.
CAUTION
Under certain circumstances, the functionmay not be able to find parking spaces – onereason may be that the sensors are disruptedby external sound sources that emit the sameultrasonic frequencies that the system workswith.
Examples of such sources include horns, wettires on asphalt, pneumatic brakes, exhaustnoise from motorcycles, etc.

NOTE
Dirt, ice and snow covering the sensorsreduce their function and can make measure-ment impossible.

Driver responsibility
The driver should keep in mind that the functionis a parking aid ‒ not an infallible fully automaticsystem. The driver must always be prepared totake control and cancel a parking sequence ifnecessary.
There are a number of things to keep in mindwhen parking, including:
The driver is always responsible for determin-ing if the space suggested by the function issuitable for parking.
Do not use the function when using snowchains or a temporary spare tire.
Do not use the function if there are anyobjects protruding from the vehicle.
Heavy rain or snowfall may inhibit PAP's abil-ity to accurately measure a parking space.
While searching and measuring the parkingspace, the function may be unable to detectobjects located far into the space.
PAP may not suggest parking spaces onnarrow streets if it does not detect sufficientspace for maneuvering the vehicle.
Use approved tires96 inflated to the correcttire pressure because this affects the func-tion's ability to provide parking assistance.
The function is based on the way the vehi-cles are parked behind and in front of yourparking space. If they are, for example,parked too close to the curb, there is a riskthat your vehicle's tires or wheel rims couldbe damaged by the curb during the parkingprocedure.
96"Approved tires" refers to tires of the same type and make as the vehicle's original, factory-installed tires.

STARTING AND DRIVING
}}
397
Brakes
The brake pedal is used to apply the vehicle'sregular brakes, which are part of the brake sys-tem.
The vehicle is equipped with two brake circuits. Ifone brake circuit is damaged, the brake pedal willgo down further when depressed. More pressurewill then be required from the driver for normalbraking effect.

WARNING
The power brakes only work when the electricmotor or combustion engine is running.
If the brake pedal is used when the engine isswitched off, greater pressure must be applied tobrake the vehicle.
In very hilly areas or when driving with a heavyload, gear position B can be used to augment thebrakes with engine braking.

Anti-lock brakes
The vehicle is equipped with an Anti-lock Braking
System (ABS2), which helps prevent the wheelsfrom locking and helps maintain steering controlwhen braking. Vibrations may be felt from thebrake pedal when ABS is operating, which is nor-mal.
After the vehicle is started, a brief test of theABS system is automatically performed when thedriver releases the brake pedal. An additionalautomatic test of the system may be performedwhen the vehicle is traveling at a low speed. Dur-ing the test, the brake pedal may feel as though itis pulsating.
Light braking charges the hybrid battery
When the brakes are applied lightly, the electricmotor braking function is used. This converts thevehicle's kinetic energy into electrical energy,which is used to charge the hybrid battery. Whenthe battery is being charged with the electricmotor braking function, this will be indicated inthe instrument panel.
When the battery is being charged with the electricmotor braking function, this will be indicated in theinstrument panel.
This function is active at speeds in the range of150-5 km/h (93-3 mph). When braking atspeeds outside of this range, or during harderbraking, the hydraulic braking system is used toaugment braking. This is indicated in the instru-ment panel with the pointer down in the red area.
