Park assist (option)
04``181 Introduction
The park assist system is designed to assist
you when driving into parking spaces, garages,
etc. It utilizes four ultrasound sensors located
in one or both bumpers to measure the dis-
tance to a vehicle, object, or a person who may
be close to the front or rear of your vehicle.
This system is available in the rear bumper
only, or in both the front and rear bumpers.
Park assist utilizes four ultrasound sensors in
the bumper(s) to measure the distance to a
vehicle, object, or a person who may be close
to the front or rear of your vehicle. An audible
signal and symbols in the audio system’s dis-
play indicate the distance to the object
WARNING
Park Assist is an information system, NOT a
safety system. This system is designed to
be a supplementary aid when parking the
vehicle. It is not, however, intended to
replace the driver's attention and judge-
ment.
Function
G018386
Park assist buttonThe system is activated automatically when the
vehicle is started. The indicator light in the but-
ton in the center console illuminates when the
system is on.•
The front park assist system is active from
the time the engine is started until the vehi-
cle exceeds a speed of approximately
10 mph (15 km/h). It is also active when the
vehicle is backing up.
•
Rear park assist is active when the engine
is running and reverse gear has been
selected.
Activating/deactivatingThe system is activated automatically when the
vehicle is started.
±
Press the Park assist button on the center
console to temporarily deactivate the sys-
tem(s).
> The indicator light in the button will go
out when the system has been deacti-
vated.
Park assist will be automatically reactivated the
next time the engine is started, or if the button
is pressed (the indicator light in the button will
illuminate).
NOTE
•
Front park assist is disengaged auto-
matically when the parking brake is
applied.
•
If the vehicle is equipped with front and
rear park assist, both systems will be
deactivated by pressing the button.

Front park assist
G021424
The distance monitored in front of the vehicle
is approximately 2.5 ft (0.8 m). The audible sig-
nal comes from the audio system's front
speakers.
It may not be possible to combine auxiliary
headlights and front park assist since these
lights could trigger the system's sensors.Faults in the systemIf the information symbol illuminates and
Park
Assist syst Service required
is shown on the
information display, this indicates that the sys-
tem is not functioning properly and has been
disengaged. Consult a trained and qualified
Volvo service technician.
CAUTION
In certain circumstances, the park assist
system may give unexpected warning sig-
nals that can be caused by external sound
sources that use the same ultrasound fre-
quencies as the system. This may include
such things as the horns of other vehicles,
wet tires on asphalt, pneumatic brakes,
motorcycle exhaust pipes, etc. This does
not indicate a fault in the system.Cleaning the sensors
G018129
Location of the front sensors
G018067
Location of the rear sensorsThe sensors must be cleaned regularly to
ensure that they work properly. Clean them
with water and a suitable car washing deter-
gent.
Ice and snow covering the sensors may cause
incorrect warning signals.
NOTE
If the sensors are obstructed by e.g., dirt,
snow, or ice, this could result in false warn-
ing signals from the park assist system.

fully. Solvents or stain removers should not be
used.
CAUTION
•
Avoid waxing or polishing plastic or rub-
ber components
•
Polishing chromed strips can wear
away or damage the surface
•
Polishes containing abrasive sub-
stances should not be used
Automatic car wash•
We do NOT recommend washing your car
in an automatic wash during the first six
months (because the paint will not have
hardened sufficiently).
•
An automatic wash is a simple and quick
way to clean your car, but it is worth
remembering that it may not be as thor-
ough as when you yourself go over the car
with sponge and water. Keeping the under-
body clean is most important, especially in
the winter. Some automatic washers do
not have facilities for washing the under-
body.
CAUTION
•
Before driving into an automatic car
wash, turn off the optional rain sensor
to avoid damaging the windshield wip-
ers.
•
Make sure that side view mirrors, auxil-
iary lamps, etc, are secure, and that any
antenna(s) are retracted or removed.
Otherwise there is risk of the machine
dislodging them.
•
Chromed wheels: Clean chrome-
plated wheels using the same deter-
gents used for the body of the vehicle.
Aggressive wheel-cleaning agents can
permanently stain chrome-plated
wheels.WARNING
•
When the vehicle is driven immediately
after being washed, apply the brakes,
including the parking brake, several
times in order to remove any moisture
from the brake linings.
•
Engine cleaning agents should not be
used when the engine is warm. This
constitutes a fire risk.
Exterior lightingCondensation may form temporarily on the
inside of the lenses of exterior lights such asheadlights, fog lights, or taillights. This is nor-
mal and the lights are designed to withstand
moisture. Normally, condensation will dissi-
pate after the lights have been on for a short
time.
Polishing and waxing•
Normally, polishing is not required during
the first year after delivery, however, wax-
ing may be beneficial.
•
Before applying polish or wax the vehicle
must be washed and dried. Tar spots can
be removed with kerosene or tar remover.
Difficult spots may require a fine rubbing
compound.
•
After polishing use liquid or paste wax.
•
Several commercially available products
contain both polish and wax.
•
Waxing alone does not substitute for pol-
ishing a dull surface.
•
A wide range of polymer-based waxes can
be purchased today. These waxes are easy
to use and produce a long-lasting, high-
gloss finish that protects the bodywork
against oxidation, road dirt and fading.
•
Do not polish or wax your vehicle in direct
sunlight (the surface of the vehicle should
not be warmer than 113 °F (45 °C).
