Volvo XC90: Specifications / Fuel tank volume
The fuel tank's refillable volume is shown in the table below.

The medium in the hydraulic brake system is called brake fluid and is used
to transfer pressure from e.g. a brake pedal via a master brake cylinder, which
in turn actuates the brake calipers...
The climate system in the vehicle uses a freon-free R1234yf refrigerant. For
information regarding the refrigerant, refer to the decal located on the inside
of the hood...
Other information:
The wipers and the washer fluid are designed to improve visibility and the
headlight pattern.
The washer nozzles are heated* automatically in cold weather to prevent the washer
fluid from freezing.
When there is approximately 1 liter (1 qt) of washer fluid remaining, a message
to refill will appear in the instrument panel...
(Option/accessory.)
Volvo recommends the use of Volvo towbars that are specially designed for
the vehicle.
NOTE
The optional detachable trailer hitch may not be available in all markets
or on all models. Consult your Volvo retailer.
