Introduction
G020295
BLIS camera
Indicator light
BLIS symbol
The Blind Spot Information System (BLIS) is an
information system that indicates the presence
of another vehicle moving in the same direction
as your vehicle in the side-view mirror's "blind
area".
CAUTION
The BLIS system should only be repaired by
a trained and qualified Volvo service tech-
nician.
WARNING
•BLIS is an information system, NOT a
warning or safety system.
•BLIS does not eliminate the need for
you to visually confirm the conditions
around you, and the need for you to turn
your head and shoulders to make sure
that you can safely change lanes.
•As the driver, you have full responsibility
for changing lanes in a safe manner.
The system is based on digital camera tech-
nology. The cameras (1) are located beneath
the side-view mirrors.
When one (or both) of the cameras have
detected a vehicle in the blind area (up to
approximately 10 ft. (3 meters) from the side of
your vehicle, and up to approximately 31 ft.
(9.5 meters) behind the side-view mirror), the
indicator light in the door panel (2) illuminates.
The light will glow continuously to alert the
driver of the vehicle in the blind area.
NOTE
The door panel indicator light illuminates on
the side of the vehicle where the system has
detected another vehicle. If your vehicle is
passed on both sides at the same time, both
lights will illuminate.
A = approx. 10 ft. (3 meters), B = approx. 31 ft.
(9.5 meters)
BLIS has an integrated function that alerts the
driver if a fault should occur with the system.
For example, if one or both of the system's
cameras are obscured, a message (see the
table on page 170) will appear in the informa-
tion display in the instrument panel. If this
occurs, clean the camera lenses. If necessary,
the system can be temporarily switched off (for
instructions see page 170).

* Option/accessory, for more information, see Introduction.169 When does BLIS function
The system functions when your vehicle is
moving at speeds above 6 mph (10 km/h).
When you pass another vehicle:
The system reacts when you pass another
vehicle at a speed of up to 6 mph (10 km/h)
faster than that vehicle.
When you are passed by another vehicle:
The system reacts if your vehicle is passed by
another vehicle at a speed of up to 43 mph
(70 km/h) faster than your vehicle.
WARNING
•BLIS does not function in sharp curves.
•BLIS does not function when your vehi-
cle is backing up.
•If you are towing a wide trailer, this may
prevent the BLIS cameras from detect-
ing other vehicles in adjacent lanes.
How BLIS functions in daylight and
darkness
Daylight
BLIS reacts to the shape of surrounding vehi-
cles. The system is designed to help detect
motor vehicles such as cars, trucks, buses,
motorcycles, etc.
DarknessBLIS reacts to the headlights of surrounding
vehicles. In order to be detected by BLIS, a
vehicle in the blind area must have its head-
lights on. This means, for example, that the
system will not detect a trailer without head-
lights that is being towed behind a car or truck.
WARNING
•BLIS does not react to cyclists or
mopeds.
•BLIS does not react to vehicles that are
standing still.
•The BLIS cameras have the same limi-
tation as the human eye. In other words,
their "vision is impaired" by adverse
weather conditions such as heavy
snowfall, intense light directly into the
camera, dense fog, etc.
LimitationsIn certain situations, the BLIS indicator light(s)
may illuminate even when there are no other
vehicles in the area monitored by the system.
NOTE
If the BLIS indicator lights illuminate occa-
sionally even when there are no other vehi-
cles in the blind area, this does not indicate
a fault in the system.
In the event of a fault,
Blind spot syst.
Service required will be displayed.
The following are several examples of situa-
tions in which the BLIS indicator light(s) may
illuminate even when there are no other vehi-
cles in the area monitored by the system.

06 Starting and driving
Rear park assist*
06
172* Option/accessory, for more information, see Introduction.
Introduction
Rear park assist
The park assist system is designed to assist
you when driving into parking spaces, garages,
etc. It utilizes four ultrasound sensors located
in the rear bumper to measure the distance to
a vehicle, object or a person who may be close
to the rear of your vehicle.
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
The system is activated automatically when the
vehicle is started. The indicator light in the but-
ton in the center console illuminates. Park
assist monitors the area behind the vehicle
when the engine is running and reverse gear
has been selected.
The distance monitored behind the vehicle is
approximately 5 ft (1.5 m). The 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's sensors.
NOTE
Rear park assist is deactivated automati-
cally when towing a trailer if Volvo genuine
trailer wiring is used.
Activating/deactivating park assist
G018389
Park Assist button (rear button in the illustration)
The system is activated automatically when the
vehicle is started.

Press the Park assist button on the center
console to temporarily deactivate the sys-
tem. The indicator light in the button will go
out when the system has been deacti-
vated.

Park assist will be automatically reactiva-
ted the next time the engine is started, or if
the button is pressed (the indicator light in
the button will illuminate).

* Option/accessory, for more information, see Introduction.173 Audible signals from the park assist
system
The 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
behind the vehicle. If the volume of another
source from the audio system is high, this will
be automatically lowered.
Faults in the system
If the information symbol illumi-
nates and PARK ASSIST
SERVICE REQUIRED is shown
on the information display, this
indicates that the system is not
functioning properly and has been disengaged.
Consult a Volvo retailer or authorized 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
Park assist 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.

07 Wheels and tires
General information
07

177
•When replacing tires, the tires with the
most tread should be mounted on the rear
wheels to reduce the chance of oversteer
during hard braking.
•Hitting curbs or potholes can damage the
tires and/or wheels permanently.
Summer and winter tires
G020325
The arrows shows the direction of rotation of the
tire
•When switching between summer and
winter tires, mark the tires to indicate
where they were mounted on the car, e.g.,
LF = left front, RR = right rear
•Tires with tread designed to roll in only one
direction are marked with an arrow on the
sidewall.
•Incorrectly mounted tires impair the car's
braking properties and ability to force
aside rain, snow and slush.
•The tires with the most tread should always
be at the rear (to reduce the risk of skid-
ding).
•Contact a Volvo workshop if you are
unsure about the tread depth.
Storing wheels and tiresWhen storing complete wheels (tires mounted
on rims), they should be suspended off the
floor or placed on their sides on the floor.
Tires not mounted on rims should be stored on
their sides or standing upright, but should not
be suspended.
CAUTION
Tires should preferably be stored in a cool,
dry, dark place, and should never be stored
in close proximity to solvents, gasoline, oils,
etc.
WARNING
•The wheel and tire sizes for your Volvo
are specified to meet stringent stability
and handling requirements. Unap-
proved wheel/tire size combinations
can negatively affect your vehicle's sta-
bility and handling.
•Any damage caused by installation of
unapproved wheel/tire size combina-
tions will not be covered by your new
vehicle warranty. Volvo assumes no
responsibility for death, injury, or
expenses that may result from such
installations.
Tire wear
Tire rotationYour vehicle has no required tire rotation. Tire
wear is affected by a number of factors such
as tire inflation, ambient temperature, driving
style, etc.

07 Wheels and tires
Tire inflation

179 Inflation placard
G032513
Tire inflation placard
Check tire inflation pressure regularly.
Tables listing the recommended inflation pres-
sure for your vehicle can be found beginning
on page 181. A tire inflation pressure placard
is also located on the driver's side B-pillar (the
structural member at the side of the vehicle, at
the rear of the driver's door opening). This plac-
ard indicates the designation of the factory-
mounted tires on your vehicle, as well as load
limits and inflation pressure.
NOTE
The placards shown indicate inflation pres-
sure for the tires installed on the car at the
factory only.
Use a tire gauge to check the tire inflation pres-
sure, including the spare, at least once a month
and before long trips. You are strongly urged
to buy a reliable tire pressure gauge, as auto-
matic service station gauges may be inaccu-
rate.
Use the recommended cold inflation pressure
for optimum tire performance and wear.
Under-inflation or over-inflation may cause
uneven treadwear patterns.
WARNING
•Under-inflation is the most common
cause of tire failure and may result in
severe tire cracking, tread separation,
or "blowout," with unexpected loss of
vehicle control and increased risk of
injury.
•Under-inflated tires reduce the load car-
rying capacity of your vehicle.
When weather temperature changes occur, tire
inflation pressures also change. A 10-degree
temperature drop causes a corresponding
drop of 1 psi (7 kPa) in inflation pressure. Checkyour tire pressures frequently and adjust them
to the proper pressure, which can be found on
the vehicle's tire information placard or certifi-
cation label.
Checking tire pressure
Cold tiresInflation pressure should be checked when the
tires are cold.
The tires are considered to be cold when
they have the same temperature as the sur-
rounding (ambient) air.
This temperature is normally reached after the
car has been parked for at least 3 hours.
After driving a distance of approximately 1 mile
(1.6 km), the tires are considered to be hot. If
you have to drive farther than this distance to
pump your tire(s), check and record the tire
pressure first and add the appropriate air pres-
sure when you get to the pump.
If checking tire pressure when the tire is hot,
never "bleed" or reduce air pressure. The tires
are hot from driving and it is normal for pres-
sures to increase above recommended cold
pressures. A hot tire at or below recommended
cold inflation pressure could be significantly
under-inflated.

WARNING
•Exceeding the permissible axle weight,
gross vehicle weight, or any other
weight rating limits can cause tire over-
heating resulting in permanent defor-
mation or catastrophic failure.
•Do not use replacement tires with lower
load carrying capacities than the tires
that were original equipment on the
vehicle because this will lower the vehi-
cle's GVW rating. Use only tires with the
correct load carrying capacity. Consult
your Volvo retailer for information.
