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 155 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 157 for more
detailed information.
5. Tire Pressure Monitoring SystemThis system monitors inflation
pressure in the tires. See page
199 for more information.
6. Fuel level warning lightWhen this light comes on, the vehi-
cle should be refueled as soon as
possible.

1. Turn signal indicator for trailer (certain
markets only)
If you are towing a trailer, this light
will flash simultaneously with the
turn signals on the trailer. If the
light does not flash when signaling,
one of the turn signals on the trailer
or on the car are not functioning properly.
2. Parking brake appliedThis light is on when the parking
brake (hand brake) is applied. The
parking brake lever is situated
between the front seats, see
page 75 for more information.
NOTE
Canadian models are equipped with the
second symbol.
3. SRS system warning lightIf this light comes on while the car
is being driven, or remains on for
longer than approximately 10 sec-
onds after the car has been
started, the SRS system's diag-
nostic functions have detected a fault in a seat
belt lock or pretensioner, a front airbag, side
impact airbag, and/or an inflatable curtain.
Have the system(s) inspected by a trained and
qualified Volvo service technician as soon as
possible.
4. Oil pressure warning light1
If the light comes on while driving,
the car, stop the engine immedi-
ately, and check the engine oil
level. If the oil level is normal and
the light stays on after restart, have
the car towed to the nearest trained and quali-
fied Volvo service technician. After hard driv-
ing, the light may come on occasionally when
the engine is idling. This is normal, provided it
goes off when the engine speed is increased.
5. Seat belt reminderThis symbol (and the seat belt
reminder light above the rear view
mirror) will light up if either front
seat occupant has not buckled his/
her seat belt. If the car is not mov-
ing, the symbols will go out after approximately
6 seconds.
6. Generator warning lightIf the light comes on while the
engine is running, have the charg-
ing system checked by an author-
ized Volvo workshop.
1On certain engines, this symbol is not used to indicate low oil pressure. Instead, a text warning is provided in the information display, see also page 218.

or braking, stop the car as quickly
as possible in a safe place, open

reservoir.

reservoir or if a Brake failure – Service
urgent message is displayed in the infor-
mation display: DO NOT DRIVE. Have the
car towed to a trained and qualified Volvo
service technician and have the brake sys-
tem inspected.
If the BRAKES and ABS warning lights come
on at the same time, this could indicate a fault
in the brake system.
In this case:
1. Stop the car in a suitable place and switch
off the engine.2. Restart the engine.
3. If both warning lights go off, no further
action is required and the car can be
driven.

been restarted, switch off the engine again
and check the brake fluid level, see
page 217 for the location of the reservoir.
Door open warning
The driver will be alerted if one of the doors, the
hood or the trunk are open or ajar.
At low speedsIf the car is moving at a speed of
less than approximately 3 mph
(5 km/h), the Information symbol in
the instrument panel will light up
and a message will be shown in the
information display indicating which door(s),
etc is not completely closed.
At higher speedsIf the car is moving at a speed
above approximately 6 mph
(10 km/h), the Warning symbol in
the instrument panel will light up
