1. Malfunction indicator light
As you drive, a computer called
On-Board Diagnostics II (OBDII)
monitors your car's engine, trans-
mission, electrical and emission
systems.
The CHECK ENGINE light will light up if the
computer senses a condition that potentially
may need correcting. When this happens,
please have your car checked by a trained and
qualified Volvo service technician as soon as
possible.
A CHECK ENGINE light may have many cau-
ses. Sometimes, you may not notice a change
in your car's behavior. Even so, an uncorrected
condition could hurt fuel economy, emission
controls, and drivability. Extended driving with-
out correcting the cause could even damage
other components in your car.
NOTE
Canadian models are equipped with the
second symbol.
2. Anti-lock Brake system (ABS)If the warning light comes on, there
is a malfunction of the ABS system
(the standard braking system will
still function).
The vehicle should be driven to a
trained and qualified Volvo service
technician for inspection, see
page 154 for additional informa-
tion.
NOTE
Canadian models are equipped with the
second symbol.
3. Rear fog lightThis symbol indicates that the rear
fog light (located in the driver's
side taillight cluster) is on.
4. Stability system STC or DSTCThis indicator symbol flashes when
the STC (Stability and Traction
control system) or the DSTC
(Dynamic Stability and Traction
control system) is actively working
to stabilize the car, see page 158 for more
detailed information.
5. Tire Pressure Monitoring SystemThis system monitors inflation
pressure in the tires. See page
200 for more information.
6. Fuel level warning lightWhen this light comes on, the vehi-
cle should be refueled as soon as
possible.

2. Blower speedThe blower speed can be
increased or decreased by
turning the knob. The blower
speed is regulated automati-
cally if AUTO is selected. The
previously set blower speed is
disconnected.
NOTE
If the knob is turned counterclockwise and
the blower indication in the display goes

switched off. The display shows the blower
symbol and
OFF.
3. RecirculationThis function can be used to
shut out exhaust fumes,
smoke, etc from the passen-
ger compartment. The air in
the passenger compartment
is then recirculated, i.e. no air
from outside the car is taken
into the car when this function is activated.
If the air in the car recirculates for too long,
there is a risk of condensation forming on the
insides of the windows, especially in winter.
TimerThe timer function minimizes the risk of fogging
or stale air when the recirculation function is
selected, see page 85 for information on set-
ting the recirculation timer.
NOTE
Recirculation is always disengaged if the
defroster button is engaged to clear ice or
condensation from the side windows.
4. DefrosterDirects airflow to the wind-
shield and side windows and
increases blower speed.
When the defroster is acti-
vated:
•Air flows to the windows at high blower
speed.
•The LED in the defroster button lights up
when this function is activated. The air con-
ditioning system is controlled to provide
maximum air dehumidification.
•The air conditioning is automatically
switched on (can be switched off by press-
ing button 6).
The air is not recirculated.
5. Airflow controlsPress one of the three buttons
in the illustration to activate
the selected airflow. A symbol
in the display above the cli-
mate control panel and a lit
LED in the selected button
indicate that the manual func-
tion has been selected. With manually selected
airflow both warm and cool air can be selected.
See also the table on page 102.
6. Air conditioning On/OffON: The air conditioning sys-
tem is engaged when the ON
light is lit and is controlled
automatically by the system
to maintain the selected tem-
perature.
OFF: The system is disengaged when the
OFF lights up
When OFF is selected and the OFF LED is lit,
the air conditioning system is deactivated.
Other functions are still controlled automati-
cally.
When Defroster (4) is selected, the air condi-
tioning system is activated for maximum dehu-
midifying.

06 Starting and driving
Blind Spot Information System (BLIS)*
06
168* 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.
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.

08 Car care
Washing and cleaning the car
08

207
Automatic washing – simple and quickWe do NOT recommend washing your car in an
automatic wash during the first few months
(because the paint will not have hardened suf-
ficiently).
An automatic wash is a simple and quick way
to clean your car, but it is worth remembering
that it may not be as thorough as when you
yourself go over the car with sponge and water.
Keeping the underbody clean is most impor-
tant, especially in the winter. Some automatic
washers do not have facilities for washing the
underbody.
CAUTION
•Before driving into an automatic car
wash, turn off the optional rain sensor to
avoid damaging the windshield wipers.
•Make sure that side view mirrors, auxil-
iary lamps, etc, are secure, and that any
antenna(s) are retracted or removed.
Otherwise there is risk of the machine
dislodging them
•Chromed wheels: Clean chrome-
plated wheels using the same deter-
gents used for the body of the vehicle.
Aggressive wheel-cleaning agents can
permanently stain chrome-plated
wheels.
WARNING
•When the car is driven immediately after
being washed, apply the brakes several
times in order to remove any moisture
from the brake linings.
•Engine cleaning agents should not be
used when the engine is warm. This
constitutes a fire risk.
Exterior lightingCondensation may form temporarily on the
inside of the lenses of exterior lights such as
headlights, fog lights, or taillights. This is nor-
mal and the lights are designed to withstand
moisture. Normally, condensation will dissi-
pate after the lights have been on for a short
time.
Polishing and Waxing
•Normally, polishing is not required during
the first year after delivery, however, wax-
ing may be beneficial.
•Before applying polish or wax the vehicle
must be washed and dried. Tar spots can
be removed with kerosene or tar remover.
Difficult spots may require a fine rubbing
compound.
•After polishing use liquid or paste wax.
•Several commercially available products
contain both polish and wax.
•Waxing alone does not substitute for pol-
ishing a dull surface.
•A wide range of polymer-based waxes can
be purchased today. These waxes are easy
to use and produce a long-lasting, high-
gloss finish that protects the bodywork
against oxidation, road dirt and fading.
•Do not polish or wax your vehicle in direct
sunlight (the surface of the vehicle should
not be warmer than 113 °F (45 °C).
CAUTION
Volvo does not recommend the use of long-
life or durable paint protection coatings,
some of which may claim to prevent pitting,
fading, oxidation, etc. These coatings have
not been tested by Volvo for compatibility
with your vehicle's clear coat. Some of them
may cause the clear coat to soften, crack,
or cloud. Damage caused by application of
paint protection coatings may not be cov-
ered under your vehicle's paint warranty.
