Do not use gasoline that contains lead as a knock inhibitor, and do not use lead additives. Besides damaging the
exhaust emission control systems on your car, lead has been strongly linked to certain forms of cancer.
Many fuels contain benzene as a solvent. Unburned benzene has been strongly linked to certain forms of cancer. If you
live in an area where you must fill your own gas tank, take precautions. These may include:
standing upwind away from the filler nozzle while refueling
refueling only at gas stations with vapor recovery systems that fully seal the mouth of the filler neck during refueling
wear neoprene gloves while handling a fuel filler nozzle.
Use of Additives
With the exception of gas line antifreeze during winter months, do not add solvents, thickeners, or other store -bought
additives to your car'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.
pg. 74 Refueling
Refueling
The fuel tank holds approximately 21.1 US gal. (80 liters) on T6 models, or 18 US gal. (68 liters) on the S80 All
Wheel Drive and the S80 2.5T Front Wheel Drive 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 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.
Fuel filler door
Press the button on the light switch panel (see illustration on page 34
) when the car is at a standstill to unlock the fuel
filler door. Please note that the fuel filler door will remain unlocked until the car begins to move forward. An audible
click ill be heard when the fuel filler door relocks.
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 131
for
additional information.
WARNING!
Never carry a cell phone that is switched on while refueling your vehicle. If the phone rings, this may cause a spark
that could ignite gasoline fumes, resulting in fire and injury.

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 overheating 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 continually in, the red section), the following precautions 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 low 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 page 132
for information on checking and topping-up the coolant level.

Number of valves24
Charge air cooler (Intercooler)
Turbocharged engines employ a turbo-compressor to force air into the engine inlet manifold and a charge air cooler to
cool the compressed inlet air. The resulting increase in air flow raises pressure in the intake manifold and increases
engine power over that developed by the normally-aspirated engine. The charge air cooler (which resembles a radiator)
is located between the turbo-compressor and inlet manifold.
