2006 VOLVO V70
Malfunction indicator lamp
On-Board Diagnostic II (OBDII): As you drive, a computer called "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 Volvo retailer 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 cleanliness, and driveability.
Extended driving without correcting the cause could even damage other components in your car.
Canadian models are equipped with this warning light:
NOTE: If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the
Malfunction Indicator Lamp may indicate a fault. However, your vehicle's performance will not be affected.
Use only Volvo original or approved fuel filler caps.
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 Volvo retailer for inspection. See
information.
Stability Traction Control (STC) system (option), or Dynamic Stability and Traction Control (DSTC)
system (option)
An indicator light will flash when STC or DSTC is actively working to stabilize the car. See
for more detailed information.
Turn signal indicator - 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, neither the trailer's turn signals nor the car's turn signals are functioning.
