used, must contain no more than 10 percent ethanol and must have an (R+M)/2 rating of 87 or higher. If you experience problems with
starting, driveability, or fuel economy with gasohol, you should discontinue its use.
Take care not to spill gasoline during refueling Gasolines containing alcohol can cause damage to painted surfaces, which may not be covered
under the New Vehicle Limited Warranty.
Do not use gasolines containing methanol (methyl alcohol, wood alcohol). This practice can result in vehicle performance deterioration and
can damage critical parts in the fuel system. Such damage may not be covered under the New Vehicle Warranty.
Fuel Tank
The fuel tank is designed to hold approx. 15.8 US gal. (60 liters), with sufficient volume left over to accommodate possible expansion of the
fuel in hot weather.
Be aware that the "usable" tank capacity will be somewhat less than the 15.8-US gal. (60-liter) maximum. When the fuel level is low, such
factors as ambient temperature, the fuel's "vapor pressure" characteristics, and terrain can affect the fuel pumps' 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. After the needle
enters the red zone, you should be able to drive approx. 25 miles (40 km) depending on driving style and conditions.

Checking oil level
The oil level should be checked each time the fuel tank is refilled. Be sure the oil level is maintained between the upper and lower marks on
the dipstick. Low oil level can cause internal damage to the engine and overfilling can result in high oil consumption. The distance between
the dipstick marks represents approx. 1 quart (1 liter) of oil.
Changing oil filter
Replace the oil filter at every oil change. If the oil filter is changed separately 1/2 US qt = .5 liters of oil should be added.
To add oil or change oil
Add oil of the same kind as already used. See engine oil section.
Coolant
Maintain fluid level between MAX and MIN marks on expansion tank.
Mixture of 50 percent Volvo anti-freeze type C (blue-green) or corresponding and 50 percent water should be used. See "Coolant" section.
Brake fluid
Check that the level is above the MIN mark, without removing the cap.
Brake fluid DOT 4. See "Brake fluid" section.
Battery
Check level in conjunction with normal service or once a year.
Electrolyte level 1/4 - 3/8 (5-10 mm) above plates. Use distilled water. Never add acid.
WARNING!
Battery gases are explosives if brought in contact with open flame or
sparks.
