06 Starting and driving
Blind Spot Information System (BLIS)–option
06``165 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
DaylightBLIS 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 function of the BLIS cameras may
be affected by intense light, or when
driving at night in areas where there are
no external sources of light (e.g., street
lights, other vehicles, etc.). In such
cases, the system may react as if the
cameras were obscured.
•
In both of the above mentioned condi-
tions, a message will appear in the infor-
mation display.
•
When driving in such conditions, the
system's function will be limited or it
may be temporarily switched off, see
page 166 for instructions.
•
When the message is no longer dis-
played, BLIS will return to normal func-
tion.
•
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, dense fog, etc.

06 Starting and drivingPark assist (Option/accessory)
06168
Introduction
G020294
Front/rear park assistThe 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.
Park assist is available in two versions:•
Rear bumper only
•
Front and rear bumpers
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.FunctionThe system is activated automatically when the
vehicle is started. The indicator light in the but-
ton in the center console illuminates.•
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.
Rear park assistThe 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.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'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.

07 Wheels and tires
Vehicle loading
07``183 Loading the vehicle
Before loading your vehicle, familiarize yourself
with the following terms for determining your
vehicle's weight ratings, with or without a
trailer, from the vehicle's Federal/Canadian
Motor Vehicle Safety Standards (FMVSS/
CMVSS) label, and the vehicle's tire informa-
tion placard:Curb weightThe weight of the vehicle including a full tank
of fuel and all standard equipment. It does not
include passengers, cargo, or optional equip-
ment.Capacity weightAll weight added to the curb weight, including
cargo and optional equipment. When towing,
trailer hitch tongue load is also part of cargo
weight.
NOTE
For trailer towing information, please refer to
the section "Towing a trailer", see
page 160.Permissible axle weightThe maximum allowable weight that can be
carried by a single axle (front or rear). These
numbers are shown on the Federal/CanadianMotor Vehicle Safety Standards (FMVSS/
CMVSS) label. The total load on each axle must
never exceed its maximum permissible weight.
Gross vehicle weight (GVW)The vehicle's curb weight + cargo + passen-
gers.
NOTE
•
The location of the various labels in your
vehicle can be found on page 262.
•
A table listing important weight limits for
your vehicle can be found on page
265.
Steps for Determining Correct Load
Limit(1) Locate the statement "the combined weight
of occupants and cargo should never exceed
XXX pounds" on your vehicle's placard.
(2) Determine the combined weight of the driver
and passengers that will be riding in your vehi-
cle.
(3) Subtract the combined weight of the driver
and passengers from XXX kilograms or XXX
pounds.(4) The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the "XXX" amount equals
1400 lbs. and there will be five 150 lbs. pas-
sengers in your vehicle, the amount of available
cargo and luggage load capacity is 650 lbs.
(1400–750 (5×150) = 650 lbs.)
(5) Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated in
Step 4.
(6) If your vehicle will be towing a trailer, load
from your trailer will be transferred to your vehi-
cle. Consult this manual
1 to determine how this
reduces the available cargo and luggage load
capacity of your vehicle.

NOTE
The transmission oil does not normally need
to be changed during the service life of the
vehicle. However, it may be necessary to
replace the oil if the vehicle is often driven
in areas of sustained temperature extremes
(hot or cold), when towing a trailer over long
distances, for prolonged driving in moun-
tainous areas, or if the vehicle is often driven
short distances in temperatures under 40 °F
(5 °C).

269 Oil specifications
Engine oil must meet the minimum ILSAC
specification GF-4, API SL, or ACEA A1/B1.
Lower quality oils may not offer the same fuel
economy, engine performance, or engine pro-
tection.
Volume: 6.1 US qts (5.8 liters).
Volume between the MIN and Max marks on
the dipstick: approximately 1.4 US qts (1.3 lit-
ers).
Volvo recommends Castrol.
Depending on your driving habits, premium or
synthetic oils may provide superior fuel econ-
omy and engine protection. Consult your Volvo
retailer or a trained and qualified Volvo service
technician for recommendations on premium
or synthetic oils.
Oil additives must not be used.
NOTE
Synthetic oil is not used when the oil is
changed at the normal service intervals.
This oil is only used at customer request, at
additional charge. Please consult a trained
and qualified Volvo service technician.
Oil viscosity (stable ambient
temperatures)
G023491
Operation in hot climatesWhen temperatures exceed 104° F (40° C) in
your area, Volvo recommends, for the protec-
tion of your engine, that you use a heavier
weight oil, such as such as SAE 5W-40 or
0W-40. See the viscosity chart.Operation in temperate climatesIncorrect viscosity oil can shorten engine life.
Under normal use when temperatures do not
exceed 104° F (40° C), SAE 5W-30 will provide
good fuel economy and engine protection. See
the viscosity chart.Extreme engine operationSynthetic oils meeting SAE 0W-30 or 0W-40
and complying with oil quality requirements arerecommended for driving in areas of sustained
temperature extremes (hot or cold), when tow-
ing a trailer over long distances, and for pro-
longed driving in mountainous areas.

symbol
G022917
The API Service Symbol "donut" is divided into
three parts:•
The upper section describes the oil's per-
formance level.
•
The center identifies the oil's viscosity.
•
The lower section indicates whether the oil
has demonstrated energy-conserving
properties in a standard test in comparison
to a reference oil.
