2005 Volvo S40

Use of Additives

With the exception of fuel line antifreeze during winter months, do not add solvents, thickeners, or other
store-bought additives to your vehicle's fuel, cooling, or lubricating systems. Overuse may damage your
engine, and some of these additives contain organically volatile chemicals. Do not needlessly expose
yourself to these chemicals.

Fuel filler door

Press the button on the light switch panel (see the illustration on
to unlock the fuel filler door. Please note that the fuel filler door will remain unlocked until the vehicle
begins to move forward. An audible click will be heard when the fuel filler door relocks.
If you intend to leave your vehicle while it is being refueled, this feature enables you to lock the doors/
trunk while leaving the fuel filler door unlocked.
You can also keep the vehicle locked if you remain inside it during refueling. The central locking button
does not lock the fuel filler door.
Be sure the fuel filler door is not obstructed and is completely closed after refueling.
Open the fuel filler cap slowly during hot weather.

Refueling

The fuel tank is designed to hold approximately 15.9 US gallons (60 liters)
over to accommodate possible expansion of the fuel in hot weather. Be aware that the "usable" tank
capacity will be somewhat less than the specified maximum. When the fuel level is low, such factors as
ambient temperature, the fuel's "Reid vapor pressure" characteristics, and terrain can affect the fuel
pump's ability to supply the engine with an adequate supply of fuel. Therefore, it is advisable to refuel as
soon as possible when the needle nears the red zone, or when the fuel warning light comes on.
1. Models with All Wheel Drive have a tank volume of 15 US gallons (57 liters).
Models with engine code 39 have a fuel tank capacity of 14.5 US gallons (55 liters). This code is the 6th
and 7th digits from the left in your vehicle's VIN number. See
plate.
