WARNING
•Bumper-attached trailer hitches must
not be used on Volvos, nor should
safety chains be attached to the
bumper.
•Trailer hitches attaching to the vehicle
rear axle must not be used.
•Never connect a trailer's hydraulic
brake system directly to the vehicle
brake system, nor a trailer's lighting
system directly to the vehicle lighting
system. Consult a trained and qualified
Volvo service technician for correct
installation.
•When towing a trailer, the trailer's safety
wire must be correctly fastened to the
hole or hook provided in the trailer hitch
on the vehicle. The safety wire should
never be fastened to or wound around
the drawbar ball.
Smoother starts with a trailerModels equipped with the V8-engine and the
6-speed automatic transmission have a built-
in function that reduces acceleration slightly in
first gear when the vehicle is towing a trailer.
This is done to help avoid wheel spin and to
make starting off smoother.
•This function is activated when the trailer's
electrical connector is plugged into theelectrical socket mounted near the trailer
hitch.
•The function is automatically deactivated
when the trailer's wiring is disconnected
from the socket. The vehicle will then
accelerate normally.
NOTE
Since this function is activated when a con-
nector is plugged into the electrical socket
near the trailer hitch, it will be activated by
any electrical equipment (e.g. bicycle racks
with lighting, etc) that is plugged in, and will
remain active until the equipment is unplug-
ged from the socket.
LevelingIf your vehicle is equipped with automatic lev-
eling, the rear suspension always retains the
correct ride height regardless of the load.
•The system adjusts the rear suspension to
the correct level after the vehicle has been
driven a short distance.
•When the vehicle is stationary, the rear
suspension lowers, which is normal.

Blind Spot Information System
06

161
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.
Darkness
BLIS reacts to the headlights of surrounding
vehicles. In order to be detected by BLIS, avehicle 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 can be temporarily switched off.
For instructions, see page 162.
•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.

07 Wheels and tires
Vehicle loading
07
176
Properly loading your vehicle will provide maxi-
mum return of vehicle design performance.
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."
Permissible axle weightThe maximum allowable weight that can be
carried by a single axle (front or rear). Thesenumbers are shown on the Federal/Canadian
Motor 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.
A table listing important weight limits for your
vehicle, is in chapter "Dimension and weights".
For the location of the various labels in your
vehicle, see page 264
Steps for Determining Correct Load
Limit
•Locate the statement "the combined
weight of occupants and cargo should
never exceed XXX pounds" on your vehi-
cle's placard.
•Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
•Subtract the combined weight of the driver
and passengers from XXX kilograms or
XXX pounds.
•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 five150 lb. passengers in your vehicle, the
amount of available cargo and luggage
load capacity is 650 lbs. (1400-750 (5 x
150) = 650 lbs.)
•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.
•If your vehicle will be towing a trailer, load
from your trailer will be transferred to your
vehicle. Consult this manual
1 to determine
how this reduces the available cargo and
luggage load capacity of your vehicle.
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. Replacement tires
with a higher limit than the originals do
not increase the vehicle's GVW rating
limitations.

09 Maintenance and servicing
Engine oil 09
208
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.
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 maintenance serv-
ices. This oil is only used at customer
request, at additional charge. Please con-
sult a trained and qualified Volvo service
technician.
Oil viscosityIncorrect viscosity oil can shorten engine life
under normal use. SAE 5W-30 will provide
good fuel economy and engine protection. See
the viscosity chart.
G023491
Viscosity chart
Extreme engine operationSynthetic oils meeting SAE 0W-30 or 0W-40
and complying with oil quality requirements are
recommended 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.

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.
