1. Malfunction indicator light
As you drive, a computer called On-Board Diagnostics II (OBDII) monitors your car's engine, transmission, 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 causes. 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
without 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 140
for
additional information.
NOTE
Canadian models are equipped with the second symbol.
3. Rear fog light
This symbol indicates that the rear fog light (located in the driver's side taillight cluster) is on.

and Traction control system) is actively working to stabilize the car. See page 142

1. Turn signal indicator for trailer (certain models)
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 applied
This light is on when the parking brake (hand brake) is applied. The parking brake lever is situated between the front
seats. See page 67
for more information.
NOTE
Canadian models are equipped with the second symbol.
3. SRS system warning light
If this light comes on while the car is being driven, or remains on for longer than approximately 10 seconds after the
car has been started, the SRS system's diagnostic functions have detected a fault in a seat belt lock or tensioner, 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 light
1
If the light comes on while driving the car, stop the engine immediately, 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 authorized Volvo retailer. After hard
driving, 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 reminder
This 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 moving, the symbols will go out after approximately 6 seconds.

check the brake fluid level in the reservoir. See page 188

in the information display: DO NOT DRIVE . Have the car towed to a trained and qualified Volvo service technician
and have the brake system inspected.

2. Restart the engine.
3. If both warning lights go off, no further action is required and the car can be driven.
