CAUTION
Objects such as chains, thin and glossy poles or low obstacles may end up in the"signal shadow" and then go temporarilyundetected by the sensors – the pulsatingtone may then unexpectedly stop insteadof becoming a constant tone as expected. The sensors cannot detect high objects, such as protruding ramps. In such situations, pay extra attention and maneuver/drive the vehicle veryslowly or stop the current parkingmaneuver – there may be a high risk ofdamage to the vehicle or other objectssince information from the sensors isnot always reliable in such situations.
CAUTION
In some circumstances, the Park Assist System may produce false warnings due toexternal sound sources with the sameultrasonic frequencies as those the systemworks with. Examples of such sources are horns, wet tires on asphalt, pneumatic brakes, exhaustnoise from motorcycles, etc.

Using Park Assist Pilot *
Park Assist Pilot (PAP 98
) 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:
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.

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 99
) compared to when they are used
by the Parking Assist system.

Leaving a parallel parking space with Park Assist Pilot *
The
Park Out function can help the driver to
pull out of a parking space when the vehicle is parallel-parked.
NOTE
Leaving a parking space with the Park Outfunction should only be used in connection with parallel parking – it does not work forperpendicular parking.
The Park Out function is acti-
vated in the center display's Function view or in Cameraview.
GREEN button indicator light – the func- tion is activated.
GRAY button indicator light – the functionis deactivated.
1. Tap
Park Out in Function view or in Cam-
era view.
2. Move the gear selector to the suitable position (e.g. D or R) for the direction in which you will be pulling out of the park-ing space.

3. Be prepared to stop the vehicle when
instructed to do so by a graphic and mes- sage in the center display. Follow theinstructions in the same way as for theparking procedure.
Note that the steering wheel can "spring"back when the procedure is completed andthe driver may need to turn the steering wheelback to the maximum position in order to pullout of the parking space. If the function determines that the driver can pull out of the parking space without any extramaneuvers, the function will be deactivated,even if it seems as though the vehicle is notcompletely out of the parking space.

Park Assist Pilot * limitations
Park Assist Pilot (PAP 100
) may not be able to
detect all conditions in all situations and func- tionality may therefore be limited.
WARNING
The parking sensors have dead/blind spots where objects cannot bedetected.
Pay particular attention to people andanimals near the vehicle.
Bear in mind that the front end of thevehicle may swing out towards oncom-ing traffic during the parking maneuver.
CAUTION
Objects situated higher than the detection area of the sensors are not included whenthe parking maneuver is calculated, whichcould cause the function to swing into theparking space too early. Such parkingspaces should be avoided for this reason.
The driver should be aware of the following limitations for Park Assist Pilot:
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.

Location of the backup reader in the tunnel console.
NOTE
When the remote key is placed in the backup reader, make sure that no othervehicle keys, metal objects or electronicdevices (e.g. cellular phones, tablets, lap-tops or chargers) are in the backup reader.Multiple vehicle keys close to each other inthe backup reader can disrupt their func-tionality.
CAUTION
If the engine has not responded after 3 attempts – wait for 3 minutes before star-ting a new attempt. Starting capabilityincreases if the starter battery is given timeto recover.
WARNING
Never remove the remote control key from
the vehicle while driving or the vehicle is being towed.
WARNING
Always remove the remote key from the passenger compartment when youleave the vehicle and make sure theignition is in mode
0.
Always put the gear selector in
P and
apply the parking brake before leavingthe vehicle. Never leave the vehicleunsupervised while the engine is run-ning.
Always open the garage door fully andmake sure that ventilation is very goodbefore starting the engine in a garage.The exhaust fumes produced by thevehicle contain carbon monoxide,which is invisible and odorless but verytoxic.
CAUTION
When starting in cold weather, the automatic transmission may shift up atslightly higher engine speeds than nor-mal until the automatic transmissionfluid reaches normal operating tem-perature.
Do not race a cold engine immediatelyafter starting. This could prevent fluidsfrom properly lubricating vital compo-nents in the engine before it hasreached the proper operating tempera-ture.
The engine should be idling when thegear selector is moved. Never acceler-ate until the gear is fully engaged.Accelerating rapidly before a gear isproperly engaged could lead to harderwear of components.
To help prevent the transmission oilfrom overheating, select
P or N when
idling at a standstill for prolonged peri-ods of time.

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.

Brakes (p. 383)
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.
