DRIVER SUPPORT
* Option/accessory.
400 Park Assist Pilot* limitations
Park Assist Pilot PAP 127
may not be able to
detect all conditions in all situations and func-
tionality may therefore be limited.
WARNING •
The PAP function is supplementary driver
support intended to facilitate driving and
help make it safer – it cannot handle all
situations in all traffic, weather and road
conditions.
• Pay particular attention to people and
animals near the vehicle.
• Bear in mind that the front end of the
vehicle may swing out towards oncoming
traffic during the parking maneuver.
• Objects situated higher than the detec-
tion area of the sensors are not included
when the parking maneuver is calculated,
which could cause PAP to swing into the
parking space too early. Such parking
spaces should be avoided for this reason.
• PAP is not a substitute for the driver's
attention and judgment. The driver is
always responsible for ensuring the vehi-
cle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.
The driver should be aware of the following limi-
tations 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 display
• when the anti-lock brakes or the Electronic
stability control are engaged - e.g. when a
wheel loses grip on a slippery road
• when the power steering works at reduced
power - e.g. during cooling due to overheat-
ing (see section "Speed-dependent steering
force").
A message in the center display will explain why
the parking sequence was cancelled.
CAUTION Under certain circumstances, PAP may not be
able to find parking spaces – one reason may
be that the sensors are disrupted by external
sound sources that emit the same ultrasonic
frequencies that the system works with.
Examples of such sources include horns, wet
tires on asphalt, pneumatic brakes, exhaust
noise from motorcycles, etc.

check to determine the reason for
the loss of brake fluid. A

Fault in pedal sensor. Symbol
Meaning A
B
Steady glow for 2 seconds after
the engine is started: Automatic
function check.
Steady glow for more than 2 sec-
onds: Fault in the ABS system. The
vehicle's regular brake system is
still working, but without the ABS
function. If the message Brake pedal Cha-
racteristics changed Service
required is displayed, the "Brake-
by-wire" system is not functioning
properly. The brake pedal will go
down further than normal and
greater pressure will be needed on
the pedal to achieve braking effect. A
Canadian models.
B US models.
WARNING •
If both symbols illuminate at the same
time and the brake level is below the MIN
mark in the reservoir or if a brake system-
related message is shown in the instru-
ment panel: DO NOT DRIVE. Have the
vehicle towed to a trained and qualified
Volvo service technician and have the
brake system inspected.
• If both symbols illuminate at the same
time and the brake level is normal (not
below the MIN mark in the reservoir) or if
a brake system-related message is
shown in the instrument panel: drive the
vehicle carefully to an authorized Volvo
workshop and have the brake system
inspected by a trained and qualified Volvo
service technician.

Automatic car washes
The vehicle should be washed as soon as it
becomes dirty. This makes the vehicle easier to
clean because dirt does not attach as strongly. It
also reduces the risk of scratches and keeps the
vehicle looking new.
Automatic car washesAn automatic car wash is a fast and easy way to
keep your vehicle clean, but it does not reach all
areas of the vehicle. For best results, Volvo rec-
ommends hand washing your vehicle or supple-
menting automatic car washes with a hand wash.
NOTE
Volvo recommends not washing the vehicle in
an automatic car wash during the first few
months; the paintwork on new vehicles takes
some time to fully harden.
CAUTION
Before driving the vehicle into a car wash,
deactivate the Automatic Braking when Sta-
tionary and Automatic Parking Brake Applica-
tion functions. If the functions are not deacti-
vated, the brake system will seize when the
vehicle is stationary and the vehicle will not be
able to roll.
CAUTION For automatic car washes in which the vehicle
is pulled forward on rolling wheels:
1.

Before washing the vehicle, make sure
that the automatic rain sensor is deacti-
vated. If it is not deactivated and inadver-
tently starts, the wiper arms could be
damaged.
2. To help prevent damage from the auto- matic car wash machinery, make sure
that the door mirrors are folded in, anten-
nas retracted or removed, and any auxili-
ary lights secured.
3. Drive into the automatic car wash.
4. Turn off the "Automatic Braking when Stationary" function using the switch in
the tunnel console.
5. Turn off the "Automatic Parking Brake Application" function in the center dis-
play's Top view.
6. Turn off the engine by turning the start knob in the tunnel console clockwise.
Hold the knob in position for at least
2 seconds.
The vehicle is now ready for the automatic car
wash.
CAUTION The system will automatically change to P
mode if the above steps are not followed. In P
mode, the wheels are locked, which they
should not be when the vehicle is being
washed in a car wash.
