1. Speedometer
2. Turn signal, left
3. Warning symbol
See the following pages for additional information.
4. Information display
The display presents information and warning messages, the ambient temperature, 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 vehicle 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
The 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.
8. Indicator and warning symbols
9. Fuel gauge (see page 250
for volumes).
When a warning light in the gauge comes on, there are approximately 2.1 US gallons (8 liters) of fuel remaining in the
tank. For more information on fuel level and consumption, see "Trip computer" on page 61
.

trip odometer.
11. Function display
This window displays information on functions such as the odometer, trip odometers, optional rain sensor, and cruise

control.
12. High beam indicator
13. Temperature gauge
The gauge indicates the temperature of the engine cooling system. If the temperature is abnormally high and the needle
enters the red zone, a message is shown in the display. Bear in mind that auxiliary lamps in front of the air intake reduce
the cooling capacity at high outside temperatures and high engine loads.

Function check
The indicator and warning symbols light
1 up when you turn the ignition key or the optional keyless drive start control to
the driving position (position II) before starting. This shows that the symbols are functioning.
When the engine starts, all symbols go out. If the engine is not started within 5 seconds, all of the symbols except
CHECK ENGINE and will go out. Certain symbols may not have their functions illustrated, depending on the car's
equipment.
The PARK BRAKE symbol will not go out until the parking brake has been released.
1On certain engines, the symbol for low oil pressure is not used. Instead, a text warning is provided in the information display, see also page 203.
Symbols in the center of the instrument panel
Warning symbol
The red warning symbol lights up to indicate a fault that could affect the car's drivability. This symbol illuminates when
the vehicle is traveling at speeds above 5 mph (7 km/h). A text explaining the nature of the fault will also be shown in the
information display. The symbol and accompanying text will remain on until the fault has been corrected. This symbol

may also light up in combination with other indicator or warning symbols.
If the red warning symbol lights up:
1. Stop the vehicle as soon as possible in a suitable location.
2. Read the message in the information display.
3. Follow the instructions provided, or contact a trained and qualified Volvo service technician. Erase the message by
pressing READ (see page 56
).
Information symbol
The yellow information symbol lights up to alert the driver to a message in the information display. This symbol
illuminates when the vehicle is traveling at speeds below 5 mph (7 km/h).
The message can be erased by pressing the READ button (see page 56
), or will disappear automatically (the length of
time required for the message to disappear varies, depending on the function indicated).
When the message "TIME FOR REGULAR SERVICE" is displayed, the text can be erased and the information symbol
light can be turned off by pressing the READ button. The text will disappear and the symbol light will go out
automatically after two minutes.

Instrument and warning symbols
Symbols - left side

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 vehicle 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 148
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.
4. Stability system DSTC
This indicator symbol flashes when the DSTC (Dynamic Stability and Traction control system) is actively working to

stabilize the car. See page 150 for more detailed information.
5. Not in use
6. Fuel level warning light
When this light comes on, there are approximately 2.1 US gallons (8 liters) of fuel remaining in the tank.

Instrument and warning symbols
Symbols - right side
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 vehicle 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 69
for more information.
NOTE
Canadian models are equipped with the second symbol.
3. SRS system warning light
If this light comes on while the vehicle is being driven, or remains on for longer than approximately 10 seconds after the
vehicle has been started, the SRS system's diagnostic 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, stop 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 vehicle towed to the nearest trained and qualified Volvo
service technician. 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 vehicle is not moving, the symbols will go out after approximately 6 seconds.
6. Generator warning light
If the light comes on while the engine is running, have the charging system checked by an authorized 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
203.

7. Fault in the brake system
If this light comes on while driving or braking, stop the vehicle as quickly as possible in a safe place, open the hood, and
check the brake fluid level in the reservoir. See page 202
for the location of the reservoir.
NOTE
Canadian models are equipped with the second symbol.
WARNING
If the fluid level is below the MIN mark in the reservoir or if a "Brake failure - Service urgent" message is displayed in
the information display: DO NOT DRIVE . Have the vehicle towed to a trained and qualified Volvo service technician
and have the brake system inspected.
If the BRAKE 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 vehicle 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 vehicle can be driven.
4. If both lights remain on after the engine has been restarted, switch off the engine again and check the brake fluid level.
See page 202
for the location of the reservoir.
Door open warning
The driver will be alerted if one of the doors, the hood, or the rear liftgate are open or ajar.
