Lane Departure Warning (LDW)–
general information

This function is designed to help reduce the
risk of accidents in situations where the vehicle
leaves its lane and there is a risk of driving off
the road or into the opposite lane. LDW con-
sists of a camera that monitors the lane’s side
marker lines. The driver is alerted by an audible
signal if the vehicle crosses a side marker line
or the road’s center dividing line.

Operation and function

LDW can be switched on or off by pressing the
button on the center console. A light in the but-
ton illuminates when the function is on.

The trip computer display shows

will be displayed.

If the vehicle unexpectedly crosses the lane’s
left or right side marker lines, the driver will be
alerted by an audible signal.

No warning signal will be given in the follow-
ing situations:

•

The turn signal is being used

•

The driver’s foot is on the brake pedal

•

The throttle pedal is pressed quickly

•

If the steering wheel is moved quickly

•

In sharp turns that cause the vehicle’s
body to sway.

Park assist*

180

Option/accessory, for more information, see Introduction.

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

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 signal

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
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

G017833

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's sensors.

NOTE

Rear park assist is deactivated automati-
cally when towing a trailer if Volvo genuine
trailer wiring is used.

Option/accessory, for more information, see Introduction.

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 system

If the information symbol illuminates and

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.

Blind Spot Information System*

Option/accessory, for more information, see Introduction.

Introduction

G021426

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 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), see
the illustration, the indicator light in the door
panel illuminates. The light will glow continu-
ously 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.

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 186) 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 185).

G021427

Areas monitored by BLIS Distance A = approx.
31 ft. (9.5 meters), Distance B = approx. 10 ft.

Blind Spot Information System*

184

Option/accessory, for more information, see Introduction.

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.

Darkness

BLIS 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 185 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.

Limitations

In 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,

Cleaning the BLIS camera lenses

In order to function optimally, the BLIS camera
lenses must be kept clean. They can be wiped
clean with a soft cloth or wet sponge.

CAUTION

•

Clean the lenses carefully to avoid
scratching.

•

The lenses are electrically heated to
help melt ice or snow. If necessary, gen-
tly brush away snow from the lenses.

Switching BLIS on and off

BLIS is automatically activated when the igni-
tion is switched on. The indicator lights will
provide confirmation by flashing 3 times.

•

The system can be switched off by press-
ing the BLIS button in the center console
(see the illustration). The indicator light in
the button goes out when the system is

General information

Economical driving conserves natural
resources

Better driving economy may be obtained by
thinking ahead, avoiding rapid starts and stops
and adjusting the speed of your vehicle to
immediate traffic conditions.

Observe the following rules:

•

Bring the engine to normal operating tem-
perature as soon as possible by driving
with a light foot on the accelerator pedal for
the first few minutes of operation. A cold
engine uses more fuel and is subject to
increased wear.

•

Whenever possible, avoid using the vehicle
for driving short distances. This does not
allow the engine to reach normal operating
temperature.

•

Drive carefully and avoid rapid acceleration
and hard braking.

•

Use the transmission's Drive (D) position
as often as possible and avoid using kick-
down.

•

Do not exceed posted speed limits.

•

Avoid carrying unnecessary items (extra
load) in the vehicle.

•

Maintain correct tire pressure. Check tire
pressure regularly (when tires are cold).

•

Remove snow tires when threat of snow or
ice has ended.

•

Note that roof racks, ski racks, etc,
increase air resistance and also fuel con-
sumption.

•

At highway driving speeds, fuel consump-
tion will be lower with the air conditioning
on and the windows closed than with the
air conditioning off and the windows open.

•

Using the onboard trip computer's fuel
consumption modes can help you learn
how to drive more economically.

Other factors that decrease gas mileage
are:

•

Dirty air cleaner

•

Dirty engine oil and clogged oil filter

•

Dragging brakes

•

Incorrect front end alignment

Some of the above mentioned items and others
are checked at the standard maintenance
intervals.

WARNING

Driving with the tailgate open: Driving with
the tailgate open could lead to poisonous
exhaust gases entering the passenger com-
partment. If the tailgate must be kept open
for any reason, proceed as follows:

•

Close the windows

•

Set the ventilation system control to air
flow to floor, windshield and side win-
dows and the blower control to its high-
est setting.

Weight distribution affects handling

At the specified curb weight your vehicle has a
tendency to understeer, which means that the
steering wheel has to be turned more than
might seem appropriate for the curvature of a
bend. This ensures good stability and reduces
the risk of rear wheel skid. Remember that
these properties can alter with the vehicle load.
The heavier the load in the cargo area, the less
the tendency to understeer.

Handling, roadholding

Vehicle load, tire design and inflation pressure
all affect vehicle handling. Therefore, check
that the tires are inflated to the recommended
pressure according to the vehicle load. See the
"Tire pressure" section. Loads should be dis-
tributed so that capacity weight or maximum
permissible axle loads are not exceeded.

05 During your trip

Driving recommendations

193

Driving through water

•

The vehicle can be driven through water up
to a depth of approximately 10 in. (25 cm),
at a maximum speed of 6 mph (10 km/h).

•

Take particular care when driving through
flowing water.

•

Clean the electrical connections for trailer
wiring after driving in mud or water.

•

When driving through water, maintain low
speed and do not stop in the water.

WARNING

After driving through water, press lightly on
the brake pedal to ensure that the brakes
are functioning normally. Water or mud can
make the brake linings slippery, resulting in
delayed braking effect.

CAUTION

•

Engine damage will occur if water is
drawn into the air cleaner.

•

If the vehicle is driven through water
deeper than 10 in (25 cm), water may
enter the differential and the transmis-
sion. This reduces the oil's lubricating
capacity and may shorten the service
life of these components.

•

Do not allow the vehicle to stand in
water up to the door sills longer than
absolutely necessary. This could result
in electrical malfunctions.

•

If the engine has been stopped while the
vehicle is in water, do not attempt to
restart it. Have the vehicle towed out of
the water.

Engine and cooling system

Under special conditions, for example when
driving in hilly terrain, extreme heat or with
heavy loads, there is a risk that the engine and
cooling system will overheat. Proceed as fol-
lows to avoid overheating the engine.

•

Maintain a low speed when driving with a
trailer up long, steep hills.

•

Do not turn the engine off immediately
when stopping after a hard drive.

WARNING

The cooling fan may start or continue to
operate (for up to 6 minutes) after the engine
has been switched off.

•

Remove any auxiliary lights from in front of
the grille when driving in hot weather con-
ditions.

•

Do not exceed engine speeds of 4500 rpm
if driving with a trailer in hilly terrain. The oil
temperature could become too high.

Conserving electrical current

Keep the following in mind to help minimize
battery drain:

•

When the engine is not running, avoid
using ignition mode II. Many electrical sys-
tems (the audio system, the optional navi-
gation system, power windows, etc) will
function in ignition modes 0 and I. These
modes reduce drain on the battery.

•

Please keep in mind that using systems,
accessories, etc., that consume a great
deal of current when the engine is not run-
ning could result in the battery being com-
pletely drained.

•

The optional 12 volt socket in the cargo
area provides electrical current even with

05 During your trip

Driving recommendations

194

the ignition switched off, which drains the
battery.

•

The optional 12 volt socket in the cargo
area provides electrical current even with
the ignition switched off, which drains the
battery.

Before a long distance trip

It is always worthwhile to have your vehicle
checked by a trained and qualified Volvo serv-
ice technician before driving long distances.
Your retailer will also be able to supply you with
bulbs, fuses, spark plugs and wiper blades for
your use in the event that problems occur.

As a minimum, the following items should be
checked before any long trip:

•

Check that engine runs smoothly and that
fuel consumption is normal.

•

Check for fuel, oil, and fluid leakage

•

Have the transmission oil level checked.

•

Check condition of drive belts.

•

Check state of the battery's charge.

•

Examine tires carefully (the spare tire as
well), and replace those that are worn.
Check tire pressures.

•

The brakes, front wheel alignment, and
steering gear should be checked by a
trained and qualified Volvo service techni-
cian only.

•

Check all lights, including high beams.

•

Reflective warning triangles are legally
required in some states/provinces.

•

Have a word with a trained and qualified
Volvo service technician if you intend to
drive in countries where it may be difficult
to obtain the correct fuel.

•

Consider your destination. If you will be
driving through an area where snow or ice
are likely to occur, consider snow tires.

Cold weather precautions

If you wish to check your vehicle before the
approach of cold weather, the following advice
is worth noting:

•

Make sure that the engine coolant contains
50 percent antifreeze. Any other mixture
will reduce freeze protection. This gives
protection against freezing down to
–31 °F (–35 °C). The use of "recycled" anti-
freeze is not approved by Volvo. Different
types of antifreeze must not be mixed.

•

Volvo recommends using only genuine
Volvo antifreeze in your vehicle's radiator.

•

Try to keep the fuel tank well filled – this
helps prevent the formation of condensa-
tion in the tank. In addition, in extremely
cold weather conditions it is worthwhile to
add fuel line de-icer before refueling.

•

The viscosity of the engine oil is important.
Oil with low viscosity (thinner oil) improves

cold-weather starting as well as decreas-
ing fuel consumption while the engine is
warming up. For winter use, 5W-30 oil, par-
ticularly the synthetic type, is recom-
mended. Be sure to use good quality oil but
do not use cold-weather oil for hard driving
or in warm weather, see page 276 for more
information on engine oil.

NOTE

Synthetic oil is not used when the oil is
changed at the normal maintenance inter-
vals except at owner request and at addi-
tional charge.

•

The load placed on the battery is greater
during the winter since the windshield wip-
ers, lighting, etc. are used more often.
Moreover, the capacity of the battery
decreases as the temperature drops. In
very cold weather, a poorly charged bat-
tery can freeze and be damaged. It is there-
fore advisable to check the state of charge
more frequently and spray an anti-rust oil
on the battery posts.

•

Volvo recommends the use of snow tires
on all four wheels for winter driving, see
page 251.

•

To prevent the washer fluid reservoir from
freezing, add washer solvents containing
antifreeze. This is important since dirt is
often splashed on the windshield during

05 During your trip

Driving recommendations

195

winter driving, requiring the frequent use of
the washers and wipers. Volvo Washer
Solvent should be diluted as follows: Down
to 14 °F (–10 °C): 1 part washer solvent and
4 parts water Down to 5 °F (–15 °C): 1 part
washer solvent and 3 parts water Down to
0 °F (–18 °C): 1 part washer solvent and
2 parts water Down to –18 °F (–28 °C):
1 part washer solvent and 1 part water.

•

Use Volvo Teflon Lock Spray in the locks.

•

Avoid using de-icing sprays as they can
cause damage to the locks.
