\b
The higher your vehicle’s speed, the
greater the distance to the vehicle
ahead, measured in feet (meters), for a
given time interval.
\b The set time interval is also used by
Adaptive Cruise Control, see page
174.
WARNINGOnly use a time interval that is suitable in
current traffic conditions.
LimitationsThe Distance Alert function uses the same
radar sensor used by Adaptive Cruise Control
and the Collision Warning system. See page
175 for more information on the radar sensor’s
limitations.
NOTE Strong sunlight, reflections, extreme light
contrasts, the use of sunglasses, or if the
driver is not looking straight ahead may
make the visual warning signal in the wind-
shield difficult to see.
WARNING \b
Bad weather or winding roads may
affect the radar sensor’s capacity to
detect vehicles ahead.
\b The size of the vehicle ahead, such as a
motorcycle, may also make it difficult to
detect. This may result in the warning
light illuminating at a shorter distance
than the one that has been set, or that
the light will not come on at all. Symbol Message Description

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\fs attention and judge-
ment. Function
Park assist button
The 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.
\b
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.
\b 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 \b

Signals from the park assist system
Views in the display
Visual indicatorThe audio system’s display gives an overview
of the vehicle’s position in relation to a
detected object.
The markers in the display indicate that one or
more of the four sensors has detected an
object. The greater the number of markers, the
closer the vehicle is to the object.
Display in a vehicle with rear park assist
only. Here, an object has been detected by
both of the right rear sensors. Display in a vehicle with both front and rear
park assist. The solid marker in this example
indicates that an object is closer than approx-
imately 1 foot (30 cm) to the right front sensor. Display in a vehicle with both front and rear
park assist. Reverse gear is selected and no
objects have been detected in front of or
behind the vehicle.
Audible signalThe Park Assist system uses an intermittent
tone that pulses faster as you come close to an
object, and becomes constant when you are
within approximately 1 ft (30 cm) of an object
in front of or behind the vehicle (example 2 in
the illustration). If there are objects within this
distance both behind and in front of the vehicle,
the tone alternates between front and rear
speakers.
If the volume of another source from the audio
system is high, this will be automatically low-
ered.
Rear park assist The distance monitored behind the vehicle is
approximately 5 ft (1.5 m). The audible signal
comes from the rear speakers.
The system must be deactivated when towing
a trailer, carrying bicycles in a rear-mounted
carrier, etc, which could trigger the rear park
assist system\fs sensors.
NOTE
Rear park assist is deactivated automati-
cally when towing a trailer if Volvo genuine
trailer wiring is used.

Front park assistThe distance monitored in front of the vehicle
is approximately 2.5 ft (0.8 m). The audible sig-
nal comes from the audio system\fs front
speakers.
It may not be possible to combine auxiliary
headlights and front park assist since these
lights could trigger the system\fs sensors.
Faults in the system
If 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
Location of the front sensors Location of the rear sensors
The 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. G031401 G031402 G031403

If any of the rear park assist
sensors detect an object that
is less than 1.3 ft (0.4 m) from
the vehicle and which is out-
side of the PAC camera’s field
of view, a “rear-view mirror”
icon will appear on the
screen. Check the mirrors for any objects near
the vehicle.

intersecting lines while backing up.
Activating the system
\bMark Automatic to activate PAC each
time reverse gear is selected.
\b Mark Off to turn off PAC completely.
Limitations
Even if it appears that a fairly small section of
the screen image is obstructed, this may mean
that a relatively large area behind the vehicle is
hidden and objects there may not be detected
until they are very near the vehicle.
NOTE Bicycle carriers or other accessories moun-
ted on the tailgate may obstruct the cam-
era\fs field of view.
Keep in mind
\b
Keep the camera\fs lens free of dirt, ice and
snow. Remove ice and snow carefully to
avoid scratching the lens.
\b Clean the lens regularly with warm water
and a suitable car washing detergent.

206 Fuel requirements
Deposit control gasoline (detergent
additives)
Volvo recommends the use of detergent gas-
oline to control engine deposits. Detergent
gasoline is effective in keeping injectors and
intake valves clean. Consistent use of deposit
control gasolines will help ensure good driva-
bility and fuel economy. If you are not sure
whether the gasoline contains deposit control
additives, check with the service station oper-
ator.
NOTE
Volvo does not recommend the use of
external fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic converter
and must use only unleaded gasoline. U.S. and
Canadian regulations require that pumps deliv-
ering unleaded gasoline be labeled "UNLEA-
DED". Only these pumps have nozzles which
fit your vehicle\fs filler inlet. It is unlawful to dis-
pense leaded fuel into a vehicle labeled "unlea-
ded gasoline only". Leaded gasoline damages
the three-way catalytic converter and the
heated oxygen sensor system. Repeated use
of leaded gasoline will lessen the effectiveness of the emission control system and could result
in loss of emission warranty coverage. State
and local vehicle inspection programs will
make detection of misfueling easier, possibly
resulting in emission test failure for misfueled
vehicles.
NOTE
Some U.S. and Canadian gasolines contain
an octane enhancing additive called methyl-
cyclopentadienyl manganese tricarbonyl
(MMT). If such fuels are used, your Emission
Control System performance may be affec-
ted, and the Check Engine Light (malfunc-
tion indicator light) located on your instru-
ment panel may light. If this occurs, please
return your vehicle to a trained and qualified
Volvo service technician for service.
Gasoline containing alcohol and ethers,
"Oxygenated fuels"
Some fuel suppliers sell gasoline containing
"oxygenates" which are usually alcohols or
ethers. In some areas, state or local laws
require that the service pump be marked indi-
cating use of alcohols or ethers. However,
there are areas in which the pumps are
unmarked. If you are not sure whether there is
alcohol or ethers in the gasoline you buy, check
with the service station operator. To meet sea-sonal air quality standards, some areas require
the use of "oxygenated" fuel.
Volvo allows the use of the following "oxygen-
ated" fuels; however, the octane ratings listed
on page 207 must still be met.
Alcohol – EthanolFuels containing up to 10% ethanol by volume
may be used. Ethanol may also be referred to
as Ethyl alcohol, or "Gasohol".
Ethers – MTBE: Fuels containing up to
15% MTBE may be used.
MethanolDo not use gasolines containing methanol
(methyl alcohol, wood alcohol). This practice
can result in vehicle performance deterioration
and can damage critical parts in the fuel sys-
tem. Such damage may not be covered under
the New Vehicle Limited Warranty.

CAUTION\b
Do not refuel with the engine running 2
.
Turn the ignition off or to position I. If the
ignition is on, an incorrect reading could
occur in the fuel gauge.
\b Avoid overfilling the fuel tank. Do not
press the handle on the filler nozzle
more than one extra time. Too much
fuel in the tank in hot weather conditions
can cause the fuel to overflow. Overfill-
ing could also cause damage to the
emission control systems. Emission controls
Three-way catalytic converter
\b
Keep your engine properly tuned. Certain
engine malfunctions, particularly involving
the electrical, fuel or distributor ignition
systems, may cause unusually high three-
way catalytic converter temperatures. Do
not continue to operate your vehicle if you
detect engine misfire, noticeable loss of
power or other unusual operating condi-
tions, such as engine overheating or back-
firing. A properly tuned engine will help avoid malfunctions that could damage the
three-way catalytic converter.
\b Do not park your vehicle over combustible
materials, such as grass or leaves, which
can come into contact with the hot exhaust
system and cause such materials to ignite
under certain wind and weather condi-
tions.
\b Excessive starter cranking (in excess of
one minute), or an intermittently firing or
flooded engine can cause three-way cata-
lytic converter or exhaust system over-
heating.
\b Remember that tampering or unauthorized
modifications to the engine, the Engine
Control Module, or the vehicle may be ille-
gal and can cause three-way catalytic con-
verter or exhaust system overheating. This
includes: altering fuel injection settings or
components, altering emission system
components or location or removing com-
ponents, and/or repeated use of leaded
fuel.
NOTE Unleaded fuel is required for vehicles with
three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy-
gen content of the exhaust gases. Readings
are fed into a control module that continuously
monitors engine functions and controls fuel
injection. The ratio of fuel to air into the engine
is continuously adjusted for efficient combus-
tion to help reduce harmful emissions.

If the fuel filler cap is not closed tightly or if the engine is running\
when the vehicle is refueled, the Check Engine Light (malfunction indi\
cator lamp) may indicate a fault. However, your vehicle\fs
performance will not be affected. Use only Volvo original or approved fu\
el filler caps.
