Park Assist Pilot (PAP)

Park Assist Pilot (PAP) helps the driver drive into
parallel or perpendicular parking spaces and
leave parallel parking spaces.

Park Assist Pilot provides assistance when park-
ing by measuring the parking space and turning
the steering wheel to guide the vehicle into the
space.

Information about the actions required by the
driver is provided in the center display in the form
of symbols, images and text.

NOTE

While PAP is active, the driver's task is to:

•

carefully monitor the area around the
vehicle

•

follow the instructions provided in the
center display

•

select a gear (D or R) when prompted

•

regulate the vehicle's speed

•

apply the brakes when necessary and
stop the vehicle

Types of parking

Parallel parking

Procedure for parallel parking

PAP helps park the vehicle as follows:

1. The system searches for and measures a

possible parking space. While this is being
done, the vehicle's speed may not exceed
approx. 20 mph ( 30 km/h). When backing
into a space, the speed may not exceed
approx. 4 mph ( 7 km/h).

2. The vehicle is steered while it is backing into

the parking space. The driver controls the
vehicle's speed.

3. The vehicle's position in the parking space is

adjusted by prompting the driver to move for-
ward and rearward while the system steers.

Perpendicular parking

Procedure for perpendicular parking

PAP helps park the vehicle as follows:

1. The system searches for and measures a

possible parking space. While this is being
done, the vehicle's speed may not exceed
approx. 4 mph ( 7 km/h).

2. The vehicle is steered while it is backing into

the parking space and its position in the
space is adjusted by prompting the driver to
select D or R while the system steers. The
driver has to control the vehicle's speed.

NOTE

PAP's

Park out

function cannot be used to

help a vehicle leave a parking space if the

Perpendicular parking

function was used

to park the vehicle.

Using Park Assist Pilot (PAP)

Park Assist Pilot (PAP) gives the driver instruc-
tions during the parking procedure. The function
can also assist when leaving a parking space.

NOTE

While PAP is active, the driver's task is to:

•

carefully monitor the area around the
vehicle

•

follow the instructions provided in the
center display

•

select a gear (D or R) when prompted

•

regulate the vehicle's speed

•

apply the brakes when necessary and
stop the vehicle

Symbols, images and text in the center display
indicate when the various steps in the parking
procedure will be carried out.

PAP can be activated if the following conditions
are met after the engine has started:

•

The vehicle may not be towing a trailer.

•

The vehicle's speed must be below approx.
20 mph (30 km/h).

•

The distance between the vehicle and a
parking space must be between 1.6-5.0 ft
(0.5-1.5 m)

NOTE

If a trailer hitch is configured in the vehicle's
electrical system, PAP will take the trailer
hitch into consideration when determining the
necessary size of a parking space.

Parking

Procedure for parking:

1. The system searches for and measures a

possible parking space.

2. The vehicle is steered while it is backing into

the parking space.

3. The vehicle's position is adjusted in the park-

ing space by moving forward and rearward.

1: Searching and measuring

Parallel parking

Perpendicular parking

PAP searches for a potential parking space and
measures it to see if there is sufficient space for
your vehicle. To start this procedure:

1. Tap the

Park In

button in

the center display's Function
view.

If necessary, slow down to:

•

a speed below 20 mph (30 km/h) for parallel
parking

•

approx. 12 mph ( 20 km/h) for perpendicular
parking.

2. Keep an eye on the display and be prepared

to stop the vehicle when you are instructed
by PAP to do so.

3. Select

Parallel parking

Perpendicular

parking

and put the transmission in reverse.

4. Keep an eye on the display and be prepared

to stop the vehicle when you are instructed
by PAP to do so.

5. Stop the vehicle when instructed to do so.

NOTE

PAP normally searches for available parking
spaces along the curb on the right (passeng-
er's) side of the vehicle. However, it can also
assist in finding and parking in spaces on the
driver's side. To do so:

•

Activate the left turn signal. PAP will then
search for a parking space on the left
side of the vehicle.

2: Backing into the parking space

Parallel parking

Perpendicular parking

DRIVER SUPPORT

}}

371

When the vehicle is backing up, PAP will steer it
into the parking space. Do as follows:

1. Check that the area behind the vehicle is

clear and put the gear selector in R.

2. Back up slowly without moving the steering

wheel. The vehicle's speed must be below
approximately 4 mph (7 km/h).

3. Keep an eye on the instrument panel and be

prepared to stop the vehicle when you are
instructed by PAP to do so.

NOTE

•

Release the wheel while PAP is steering
the vehicle.

•

The steering wheel must be able to turn
freely.

•

For PAP to function optimally, wait until
the steering wheel is no longer turning
before beginning the next phase of the
parking procedure.

3: Adjusting the vehicle's position

Parallel

Perpendicular

After the vehicle has backed into the parking
space, its position in the space has to be

adjusted by driving slightly forward and backing
up.

1. Put the gear selector in D, wait until the

steering wheel has turned and drive forward
slowly.

2. Stop the vehicle when you are instructed by

PAP to do so.

3. Put the gear selector in R, back up slowly

and stop when you are instructed by PAP to
do so.

When the parking procedure is finished (this will
be indicated by a text message and a graphic
image), PAP switches off automatically. If neces-
sary, the driver may need to make minor adjust-
ments to ensure that the vehicle is parked cor-
rectly.

CAUTION

The warning distance is shorter when PAP is
using the sensors than when Park Assist is
using them.

Leaving a parking space

This function can only be used
for a vehicle that has been par-
allel parked and is activated in
the center display's Function
view.

DRIVER SUPPORT

* Option/accessory, for more information, see Introduction.

372

1. Tap the

Park out

button in the center display's

Function view.

2. Use the turn signal to indicate the direction in
which the vehicle should leave the parking space.

3. Follow the instructions provided in the center
display. The procedure is the same as when park-
ing the vehicle.

The steering wheel may turn back slightly when
the function is completed and the driver may
have to turn the back before leaving the parking
space.

If PAP determines that the driver can leave the
parking space without assistance, the function
will deactivate before the vehicle is completely
out of the space.

The PAP parking sequence is cancelled

A parking sequence will be cancelled:

•

if the vehicle is driven too fast: above approx.
4 mph (7 km/h)

•

if the driver taps

Cancel

in the center display

•

if the driver moves the steering wheel with
sufficient force.

•

if the anti-lock brakes or Electronic Stability
Control are activated (e.g., if a wheel begins
to spin or lose traction)

In such cases, a text message will explain why
the parking sequence was cancelled.

NOTE

•

PAP will not function correctly if its sen-
sors are obstructed by dirt, snow, etc.

•

In certain situations, PAP may not be able
to measure a parking space. This could
be due to external sources of sound (e.g.,
a vehicle's horn, tires on wet asphalt,
pneumatic brakes, noise from a motorcy-
cle's exhaust, etc.) emitting ultrasound
using approximately the same frequen-
cies as PAP.

Points to keep in mind

PAP is a parking aid only and the driver should
always be prepared to take control and cancel a
parking sequence. This can be due to one or
more of the following factors:

•

PAP's function is based on the way that the
vehicles are parked behind and in front of
your parking space. If they are, for example,
parked too close to the curb, there is a risk
that your vehicle's tires or wheel rims could
be damaged by the curb during the parking
procedure.

•

PAP is intended to provide parking assis-
tance on straight streets, not sections of
street with curved or irregular curbs. Be sure
that your vehicle is parallel to the curb when
PAP measures the parking space.

•

PAP may not be able to provide parking
assistance on narrow streets due to lack of
space to maneuver the vehicle. In situations
like this, it may help to drive between
1.5-5.0 ft (0.5-1.5 m) from the side of the
road where the parking space is located.

•

Use only approved tires with the correct infla-
tion pressure because this affects PAP's
capacity to provide parking assistance.
Changing to a different approved tire size
may affect PAP's parameters. Consult a
trained and qualified Volvo service technician.

DRIVER SUPPORT

* Option/accessory, for more information, see Introduction.

373

•

Heavy rain or snow may inhibit PAP's
capacity to correctly measure a parking
space.

•

Do not use PAP when using snow chains
and/or a temporary spare tire.

•

Do not use PAP if there are any objects pro-
truding from the vehicle.

WARNING

•

The front end of your vehicle may turn out
toward oncoming traffic during the park-
ing procedure.

•

Objects located above the parking sen-
sors' field of vision are not included when
PAP measures a parking space. For this
reason, PAP may turn into the parking
space too soon. Avoid parking spaces of
this type.

•

The driver is always responsible for deter-
mining if PAP has selected a suitable
parking space.

Maintenance

Location of the PAP sensors

In order for PAP to function correctly, these sen-
sors must be cleaned regularly with water and a
suitable car washing detergent.

Brakes

The brake system is a hydraulic system consist-
ing of two separate brake circuits. If a problem
should occur in one of these circuits, it is still
possible to stop the vehicle with the other brake
circuit.

Brake system

If one of the brake circuits is not functioning,
more pressure will be needed on the brake pedal
(and the pedal will go down farther) for normal
braking effect.

If the brake pedal must be depressed farther
than normal and requires greater foot pressure,
the stopping distance will be longer.

Pressure on the brake pedal is enhanced by the
power braking function.

WARNING

If the vehicle does not have electrical current
and both the electric motor and gasoline
engine are switched off, the brakes cannot be
used to stop the vehicle.

When the Hill Start Assist function is being used,
it will take slightly longer for the brake pedal to
return to its normal position if the vehicle is
parked on an incline or uneven surface.

When driving in very hilly areas or if the vehicle is
carrying a heavy load, using brake mode B to
augment the brakes or the

Off Road

* drive

mode can also be used on steep downgrades to
increase the engine braking effect at low speeds.

Anti-lock Braking System ABS

The ABS system helps to improve vehicle control
(stopping and steering) during severe braking
conditions by limiting brake lockup.

When ABS is operating, there may be some
vibration in the brake pedal, which is normal.

The system performs a brief self-diagnostic test
when the engine has been started and driver
releases the brake pedal. Another automatic test
may be performed when the vehicle first reaches
a speed of approximately 6 mph (10 km/h). The
brake pedal will pulsate several times and a
sound may be audible from the ABS control
module, which is normal.

Function check when the engine is
started

A Plug-in Hybrid is equipped with a "brake by
wire" brake system. A function check is per-
formed each time the engine is started and the
driver depresses the brake pedal to move the
gear selector from P.

In certain cases, a message may appear in the
instrument panel saying that pressure on the
brake pedal is too low. Press harder on the pedal.

Light braking charges the hybrid battery

When the brakes are applied lightly, the electric
motor's braking function is used, which converts

kinetic energy into electricity that is used to
charge the hybrid battery. This is indicated in the
instrument panel, see also the article "General
information about the XC90 T8 Twin Engine
Plug-in Hybrid".

Battery charging gauge in the instrument panel

This function is active at speeds from approx.
90 mph (150 km/h) down to 3 mph (5 km/h).
When braking at speeds outside of this range or
during harder braking, the hydraulic brake system
is used.

Cleaning the brake discs

Coatings of dirt and water on the brake discs
may result in delayed brake function. This delay is
minimized by cleaning the brake linings.

Cleaning the brake pads is advisable in wet
weather, prior to long-term parking, and after the
vehicle has been washed. Do this by braking gen-
tly for a short period while the vehicle is moving.

Driving on wet or salted roads

Prolonged driving on wet or salted roads can
affect brake function and increase stopping dis-
tance. Be sure to keep a safe distance to the
vehicle 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 the
vehicle and performing a visual inspection of the
brake pads.

WARNING

•

If the vehicle has been driven immediately
prior to a brake pad inspection, the wheel
hub, brake components, etc., will be very
hot. Allow time for these components to
cool 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 and
clean, and should not be damaged.

•

Be sure the jack is on a firm, level, non-
slippery surface.

•

No objects should be placed between the
base of jack and the ground, or between
the jack and the attachment bar on the
vehicle.

•

The jack must correctly engage the jack
attachment.

•

Never allow any part of your body to be
extended under a vehicle supported by a
jack.

Brake functions

The vehicle's standard braking features are aug-
mented by a number of auxiliary help functions.

In addition to the wheel brakes and the parking
brake, the vehicle is equipped with several auto-
matic brake assist functions. These systems help
the driver by e.g., keeping the vehicle stationary
when the brake pedal is not depressed (at a traf-
fic light or intersection), when starting up a hill or
when driving down a hill.

These systems include:

•

Auto-hold brakes

•

Hill Start Assist

•

Braking assist after a collision

•

Auto-hold brake function

With the Auto-hold brake function, the driver can
release the brake pedal and the brakes will
remain applied, for example, when the vehicle
has stopped at a traffic light or intersection.

When the vehicle is no longer moving forward,
Auto-hold applies the brakes automatically, either
using the normal brakes or the parking brake.
The brakes will be released when the accelerator
pedal is depressed.

If the driver's door is opened or the engine is
turned off, the parking brake will be applied auto-
matically.

Auto-hold control

Auto-hold control and indicator light

Turn Auto-hold on or off by pressing the control

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 at
which the ABS system is activated. The function
is deactivated when pressure on the brake pedal
decreases.

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 the
effect of a secondary collision, the brakes are
applied automatically to help bring the vehicle to
a stop.

The brake lights and hazard warning flashers will
be activated and the flashers will remain on after
the vehicle has come to a standstill. The parking
brake will then be applied automatically.

In a situation where stopping the vehicle may not
be desirable, the driver can override this system
by pressing the accelerator pedal.

This feature can only function if the brake system
is intact after the collision.

Emergency brake lights

The emergency brake lights activate in the event
of hard braking/rapid deceleration at most nor-
mal driving speeds or if the ABS system is acti-
vated. This function causes an additional taillight
on each side of the vehicle to illuminate to help
alert vehicles traveling behind.

Once the emergency brake lights have been acti-
vated, if the driver releases the brake pedal, the
brake lights will return to their normal function.

Hill Descent Control (HDC)

HDC is a type of low-speed automatic engine
brake and makes it possible to increase or
decrease the vehicle's speed on steep downhill
gradients using only the accelerator pedal, with-
out applying the brakes.

HDC is integrated into the

Off Road

drive

mode.

HDC is particularly useful when driving down
steep hills with rough surfaces, and where the
road may have slippery patches.

WARNING

HDC does not function in all situations, and is
a supplementary braking aid. The driver has
full responsibility for driving in a safe manner.

Function

HDC allows the vehicle to roll forward or in
reverse at very low speed with enhanced engine
braking. However, speed can be adjusted with
the accelerator pedal. When the accelerator
pedal is released, the vehicle will return to very
low speed.

The driver can use the brakes to slow or stop the
vehicle at any time.

HDC is activated along with Low Speed Control
(LSC), which together make driving on slippery
surfaces at low speeds easier.

STARTING AND DRIVING

* Option/accessory, for more information, see Introduction.

381

When HDC and LSC are activated, this changes
the response from the accelerator pedal and
engine.

Activating HDC

This function can be activated in different ways,
depending on how the vehicle is equipped.

Using the drive mode control

Select the

Off Road

drive mode to activate the

function.

Select a different drive mode to turn HDC off. If
this is done while the vehicle is on a steep down-
grade, engine braking will decrease gradually.

Hill Start Assist

Hill Start Assist (HSA) helps prevent the vehicle
from rolling backwards when starting up a hill. If
you are backing up a hill, HSA helps prevent the
vehicle from rolling forward.

HSA makes it easier to start or back up on a hill
by retaining pressure on the brake pedal for sev-
eral seconds after the pedal has been released in
order to keep the vehicle at a standstill.

The brakes will be released after several seconds
or when the driver presses the accelerator pedal.

HSA is available even if the Auto-hold braking
function is turned off.
