3. Warning symbol - See the following pages for additional information.
4. Information display - The display presents information and warning messages, the ambient temperature, and the
clock, etc. When the ambient temperature is between 23° and 36°F (-5° and +2°C), a snowflake symbol is shown in
the display. This symbol serves as a warning for possible slippery road surfaces. Please note that this symbol does not
indicate a fault with your car. At low speeds, or when the car is not moving, the temperature readings may be slightly
higher than the actual ambient temperature.
5. Information symbol - See the following pages for additional information.
6. Turn signal, right
7. Tachometer - Shows engine speed in thousands of revolutions per minute (rpm). Do not drive continuously with the
needle in the red area of the dial, which indicates maximum allowable engine rpm range. Instead, shift to a higher gear
or slow the vehicle down. The engine management system will automatically prevent excessively high engines speeds.
This will be noticeable as a pronounced unevenness in engine speed.

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.
