open gas tank VOLVO S80 2001 Owners Manual

Refueling
The fuel tank is designed to hold approximately 21.1 US gal. (80 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 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 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, or when the
fuel warning light comes on.
Fuel filler door
If you lock your car with the key or remote control, the fuel filler door will lock after a 10- minute delay. If you intend
to leave your car 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 car 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 conditions.
NOTE: During a transitional period, a small number of service stations may still have fuel nozzles that are not
compatible with the fuel filler neck on cars equipped with the evaporative control system. Please refer to page 109
for
additional information.
CAUTION:
· Do not refuel with the engine running *. Turn the ignition off or to position I. If the ignition is on, an incorrect
reading could occur in the fuel gauge.
· After refueling, close the fuel filler cap by turning it clockwise until it clicks into place *.
· Allow for fuel expansion by not overfilling the tank. Overfilling could also cause damage to the emission control
systems.
· Avoid spilling gasoline during refueling. In addition to causing damage to the environment, 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 Limited Warranty.
* If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Check Engine
Light (Malfunction Indicator Lamp) may indicate a fault. However, your vehicle's performance will not be affected.
Use only Volvo original or approved fuel filler caps.

· Note that roof racks, ski racks, etc., increase air resistance and also fuel consumption.
· Avoid using automatic transmission kickdown feature unless necessary.
· However, at higher driving speeds, fuel consumption will be lower with the air conditioning on and the windows
closed than with the air conditioning off and the windows open.
· Using the onboard trip computer's fuel consumption modes can help you learn how to drive more economically.
Other factors which decrease gas mileage are:
· Worn or dirty spark plugs
· Incorrect spark plug gap
· Dirty air cleaner
· Dirty engine oil and clogged oil filter
· Dragging brakes
· Incorrect front end alignment
Some of the above mentioned items and others are checked at the standard Maintenance Service intervals.
NOTE: Vehicles equipped with automatic transmissions should use (D)rive as often as possible and avoid using
"kickdown" to help improve fuel economy.
Cooling system
The risk for engine overheating is greatest, especially in hot weather, when:
· Towing a trailer up steep inclines for prolonged periods at wide open throttle and low engine rpm.
· Stopping the engine suddenly after high speed driving (so-called "after-boiling" can occur).
· To avoid overheating, the following rules should be followed: Do not drive for prolonged periods at engine speeds
above 4500 rpm if you are towing a trailer in hilly terrain.
· Reduce speed when towing a trailer up long, steep inclines. The risk of overheat -ing can be reduced by switching off
the air conditioning system for a short time.
· Do not let the engine idle unnecessarily for prolonged periods.
· Do not mount auxiliary lamps in front of the grill. When the risk of overheating is imminent, or in the event of
overheating (the temperature gauge goes repeatedly into, or stays continual-ly in, the red section), the following
precau-tions should be taken:
· Switch off the air conditioning system.
· Pull off the road, away from traffic, stop the car and put the gear selector into Park. Do not stop the engine!
· Switch the heater to full (maximum) position. Increase the engine speed to approx. 2000 rpm (twice idling speed)
until the temperature begins to drop.
· If the warning light in the center of the instrument panel is red, and the message "Coolant level lo stop engine" is
displayed, switch off the engine as soon as possible.
WARNING!
Do not remove coolant expansion tank cap. The coolant will be extremely hot.
If necessary, see See page 110
for information on checking and topping-up the coolant level.
