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, 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.
8. Indicator and warning symbols
9. Fuel gauge (see page 252
for fuel tank volume). 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 63
.

10. Trip odometer reset button - The trip odometers are used to measure short distances. Press the button briefly to
switch between the odometer for the car's total mileage and the two trip odometers, T1 and T2. A long press (more
than 2 seconds) resets the currently selected 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.

The defroster function should be used to remove fog or mist from the inside of the windows. Keeping the windows
clean with a commercially available window washing spray will also help prevent fogging or misting.
Climate control maintenance
Special tools and equipment are required to maintain and carry out repairs on the climate system. Work of this type
should only be done by a trained and qualified Volvo service technician.
Refrigerant
Volvo cares about the environment. The air conditioning system in your car contains a CFC-free refrigerant - R134a.
This substance will not deplete the ozone layer. The system contains 1.2 lbs (530 g) R134a (HFC 134a), and uses PAG
oil.
Passenger compartment filter
Replace the cabin air filter with a new one at the recommended intervals. Please refer to your Warranty and Service
Records Information booklet, or consult your Volvo retailer for these intervals. The filter should be replaced more
often when driving under dirty and dusty conditions. The filter cannot be cleaned and therefore should always be
replaced with a new one.
NOTE
There are different types of cabin air filters. Ensure that the correct type is installed.
Display
The display above the climate control panel shows the climate settings that have been made.
Personal settings
There are two functions in the climate system that can be set to your preferences:
Blower speed to Auto mode (models with ECC only).
Timer controlled recirculation of the air in the passenger compartment.
For information about how to make these settings, see the Personal settings section on page 77
.
