Using Park Assist Pilot *
Park Assist Pilot (PAP 119
) helps the driver
park using three different steps. The function can also help the driver pull out of a parkingspace.
The function measures the space and steers 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) – an audi-ble signal indicates when the driver needsto change gears
regulating and maintaining a safe speed
applying the brakes and stopping the vehi-cle.
Information about the actions required by thedriver are provided in the center display usingsymbols, graphics and/or text. The function can be activated if the following criteria have been met after the engine isstarted:
No trailer is hitched to the vehicle
Your vehicle's speed is lower than30 km/h (20 mph).
NOTE
The distance between the vehicle and parking spots should be 0.5–1.5 meters(1.6–5.0 ft) when the function is lookingfor parking.
Parking with Park Assist PilotThe function helps park the vehicle using the following steps:
1. The system searches for and measures
potential parking spaces.
2. The vehicle is steered while it is backing into the parking space.
3. The vehicle is positioned in the parking space (the driver may be prompted to shift gears and apply the brakes).
Searching and measuring potential parking spots
The function can be activated in the center display's Func-tion view. It can also be accessed from the camera views.
GREEN button indicator light – the func- tion is activated.
GRAY button indicator light – the functionis deactivated.

Positioning the vehicle in the parking space
Parallel parking positioning overview.
Perpendicular parking positioning overview.
1. Move the gear selector to the gear instruc-
ted by the system. Wait until the steering wheel turns and then drive slowly forward.
2. Be prepared to stop the vehicle when instructed 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 when instructed to do so by a graphic and mes- sage in the center display.
The function will switch off automatically anda graphic and message will appear to indicatethat parking has been completed. Adjust-ments can always be made be the driver after-ward. Only the driver can determine when thevehicle is correctly parked.
CAUTION
The warning distance is shorter when the sensors are used by Park Assist Pilot (PAP 120
) compared to when they are used
by the Parking Assist system.
Auto-brake during a parking sequenceIf, while parking, the parking sensors detect a vehicle or pedestrian in the vehicle's intendeddirection of travel behind or in front of the vehicle, the auto-brake function will bring thevehicle to a standstill. A pop-up message will then appear in the instrument panel and the driver can tap
Cancel to cancel the parking sequence orResume to continue the parking sequence.
After selecting
Resume:
–Check that the area around the vehicle is free of obstructions and follow the instruc-tions on the center display, such as:
To continue – Gently accelerate away
from object.

The parking sequence is cancelledA 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 dis-
play
when the anti-lock brakes or the Elec- tronic stability control are engaged - e.g.when a wheel loses grip on a slippery road
when speed-dependent power steeringwheel resistance is working at reducedpower – e.g. during cooling due to over-heating
A message in the center display will explainwhy the parking sequence was cancelled.
CAUTION
Under certain circumstances, the function may not be able to find parking spaces –one reason may be that the sensors aredisrupted by external sound sources thatemit the same ultrasonic frequencies thatthe system works with. Examples of such sources include horns, wet tires on asphalt, pneumatic brakes,exhaust noise from motorcycles, etc.
NOTE
Dirt, ice and snow covering the sensors reduce their function and can make meas-urement impossible.
Driver responsibilityThe driver should keep in mind that the func- tion is a parking aid ‒ not an infallible fully
automatic system. The driver must always beprepared to take control and cancel a parkingsequence if necessary. There are a number of things to keep in mind when parking, including:
The driver is always responsible for deter-mining if the space suggested by the func- tion is suitable for parking.
Do not use the function when using snow chains 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'sability to accurately measure a parkingspace.
While searching and measuring the park-ing space, the function may be unable todetect objects located far into the space.
PAP may not suggest parking spaces onnarrow streets if it does not detect suffi-cient space for maneuvering the vehicle.
Use approved tires 122
inflated to the cor-
rect tire pressure because this affects thefunction's ability to provide parking assis-tance.
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 rimscould be damaged by the curb during theparking procedure.
Perpendicular parking spaces may not bedetected or may be suggested unneces-sarily if a parked vehicle is sticking outmore than other parked vehicles.
The function is intended to provide park-ing assistance on straight streets, not sec-tions of street with sharp curves or bends.Always make sure that your vehicle is par-allel to relevant parking spaces when thefunction is measuring the parking space.

Brake functions
The vehicle's brakes are used to reduce speed or prevent the vehicle from rolling.
In addition to the wheel brakes and parking brakes, the vehicle is also equipped with anumber of automatic brake assist functions.These systems provide assistance by e.g. thedriver not needing to depress the brake pedalat a traffic light, when starting up a hill orwhen driving down a hill. Depending on how the vehicle is equipped, the following brake assist functions may beincluded:
Auto-hold brake function at a standstill(Auto Hold)
Hill Start Assist (Hill Start Assist)
Braking assist after a collision
City Safety
Hill Descent Control (Hill Descent Control)

Brakes
The brake pedal is used to apply the vehicle's regular brakes, which are part of the brakesystem.
The vehicle is equipped with two brake cir- cuits. If one brake circuit is damaged, thebrake pedal may go down further whendepressed. More pressure will then berequired from the driver for normal brakingeffect. The driver's pressure on the brake pedal is enhanced by a power braking function.
WARNING
Power braking only functions if the engine is running.
If the brake pedal is used when the engine is turned off, the pedal will feel stiffer than usualand greater pressure must be applied to brakethe vehicle. In very hilly areas or when driving with a heavy load, engine braking in manual gear should beused to augment the brakes. Engine braking ismost effective if the same gear is used bothuphill and downhill. Use the Off Road drivemode to increase the engine braking effectwhen driving on steep downgrades at lowspeeds.
Anti-lock brakesThe vehicle is equipped with an Anti-lock Braking System (ABS 2
), which helps prevent
the wheels from locking and helps maintain steering control when braking. Vibrations maybe felt from the brake pedal when ABS isoperating, which is normal. After the vehicle is started, a brief test of the ABS system is automatically performed whenthe driver releases the brake pedal. An addi-tional automatic test of the system may beperformed when the vehicle is traveling at alow speed. During the test, the brake pedalmay feel as though it is pulsating.

WARNING
If the warning symbols for both brake fault and ABS fault are lit simultaneously, theremay be a fault in the brake system.
If the brake fluid reservoir level is nor- mal when this occurs, drive carefully tothe nearest workshop to have thebrake system checked - an authorizedVolvo workshop is recommended.
If the brake fluid has fallen below theMIN
level in the brake fluid reservoir,
the vehicle should not be driven untilthe brake fluid has been filled. The rea-son for the brake fluid loss must bechecked.

Brake Assist System The brake enhancing system, (BAS 3
), helps
increase braking force and can thereby reduce braking distance.
The system monitors the driver's braking hab- its and increases braking force when neces-sary. Braking force can be increased up to thepoint at which the ABS intervenes.
NOTE
When BAS is activated, depress and hold down the brake pedal as long as needed.

Braking on wet roadsProlonged driving in heavy rain without brak- ing may cause braking effect to be slightlydelayed the first time the brakes are applied.
This may also occur after washing the vehicle. It will then be necessary to apply greater pres-sure to the brake pedal. You should thereforemaintain a greater distance to the vehicleahead. Firmly apply the brakes after washing the vehicle or driving on wet roads. This helpswarm up the brake discs, enabling them to drymore quickly and protecting them against cor-rosion. Consider the current traffic situationwhen braking.

Braking on salted roads (p. 405)
Braking on salted roads
When driving on salted roads, a layer of salt may form on the brake discs and brake pads.
This could increase stopping distance. Main- tain an extra large safety distance to the vehi-cle ahead. Make sure to also:
Apply the brakes from time to time to helpremove salt. Make sure braking does notpose a risk to any other road users.
Gently apply the brakes when you havefinished driving and before driving again.

Maintenance of the brake system
Regularly check the brake system compo- nents for wear.
To keep the vehicle as safe and reliable as possible, follow the Volvo service schedulespecified in the Warranty and MaintenanceRecords Information booklet. After replacingbrake pads and brake discs, braking effect isnot adapted until they are "broken in" by driv-ing a few hundred kilometers (miles). Com-pensate for the reduced braking effect byapplying greater pressure to the brake pedal.Volvo recommends only using brake padsapproved for your Volvo.
CAUTION
The brake system's components should be regularly checked for wear. Contact a workshop for advice on how to do this or let a workshop perform theinspection - an authorized Volvo workshopis recommended.

Parking brake
The parking brake helps keep the vehicle sta- tionary by mechanically locking two wheels.
The parking brake controls are located in the tunnel console between the seats.
When the electric parking brake is being applied, a faint sound can be heard from thebrake's electric motor. This sound can also beheard during the automatic function check ofthe parking brake. If the vehicle is stationary when the parking brake is activated, it will only be applied to therear wheels. If it is activated while the vehicleis moving, the normal brakes will be used onall four wheels. Braking will be transferred toonly the rear wheels when the vehicle isalmost stopped.

Auto-hold brakes
With the Auto-hold brake function, the driver can release the brake pedal and the brakeswill remain applied, for example, when thevehicle has stopped at a traffic light or inter-section.
When the vehicle stops, the brakes are acti- vated automatically. The function can useeither the normal brakes or the parking brakesto keep the vehicle stationary and works onflat surfaces or hills. If the driver has their seatbelt fastened and/or if the driver's door isclosed, the brakes will disengage automati-cally when the vehicle starts driving.
NOTE
When braking to a stop on an uphill or downhill gradient, depress the brake pedalwith slightly more force than usual beforereleasing to ensure that the vehicle cannotmove at all.
The parking brake is activated if
the vehicle is switched off.
the driver's door is opened
the driver's seat belt is removed
the vehicle has been stationary for a pro- longed period of time (5-10 minutes)
