pg. 19 Warning lights
STC disengaged
The indicator light (
) in the instrument panel will be ON when you have switched the Stability and Traction Control
system (STC) OFF using the button on the dashboard (see page 23
). The light will also come on if there is a fault in the
STC system or to indicate that the brakes have overheated. The light will go out when the brake temperature returns to
normal.
The
symbol will flash when STC is actively regulating power to the drive wheels. Normal power may be reduced at
this time. This is normal as power is momentarily reduced to help keep the drive wheels from losing traction and
spinning.
Anti-lock Brake system (ABS)
If the warning lamp lights up there is a malfunction of the ABS system (the standard braking system will however
function). The vehicle should be driven to a Volvo retailer for inspection.
See page 74
for additional information.
Canadian models are equipped with this warning light:
Coolant level sensor
If this light comes on while driving, the coolant level is low. The coolant level in the expansion tank should be
checked immediately and topped up if necessary. The cooling system should be inspected by an authorized Volvo
retailer.
Mode "W" engaged
The lamp will light up when the Winter/Wet starting mode is engaged or if gears "3" or "L" are selected.
If the warning lamp begins to flash , this means that there is a fault in the automatic gearbox. Contact Your Volvo
retailer.
Supplemental Restraint System (SRS)
If the light comes on (or stays on after the vehicle has started), the SRS diagnostic system has detected a fault. Drive to
an authorized Volvo retailer for an inspection of the system. See the SRS section for more information.
Generator warning light
If the light comes on while the engine is running, have the charging system checked.

NOTE - ENGINE OIL:
Although some oil consumption occurs during normal engine operation, more oil is consumed when the engine is new
as the internal parts generate higher friction while wearing in to each other. From the time the engine is new until
the first service is performed, the oil consumption could be higher than normal. For this reason, it is especially
important to check the oil every time you refuel your car during this period. See page 116-117.
In general, the rate of oil consumption depends on such factors as: engine temperature, length of trip, driving
conditions, oil viscosity and quality, engine speed and acceleration/deceleration.
Checking your engine oil level each time the car is refueled is one of the most important items you can perform to
help keep your car in good running order.

Posted speed limits should not be exceeded.
Deposit control (detergent) gasoline
Volvo recommends the use of detergent gasoline to control engine deposits. Detergent gasoline is effective in keeping
injectors and intake valves clean. Consistent use of deposit control gasolines will help ensure good driveability and
fuel economy. If you are not sure whether the gasoline contains deposit control additives, check with the service
station operator.
Unleaded fuel
Each Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. and Canadian regulations
require that pumps delivering unleaded gasoline be labelled "UNLEADED". Only these pumps have nozzles which fit
your car's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labelled "unleaded gasoline only". Leaded
gasoline damages the three-way catalytic converter and the heated oxygen sensor system. Repeated use of leaded
gasoline will lessen the effectiveness of the emission control system and could result in loss of emission warranty
coverage. State and local vehicle inspection programs will make detection of misfueling easier, possibly resulting in
emission test failure for misfueled vehicles.
NOTE : Some U.S. and Canadian gasolines contain an octane enhancing additive called methyl-cyclopentadienyl
manganese tricarbonyl (MMT). If such fuels are used, your Emission Control System performance may be affected,
and the Malfunction Indicator Lamp located on your instrument panel may light. If this occurs, please return your
vehicle to an authorized Volvo retailer for service.
Octane rating
Volvo engines are designed for optimum performance on unleaded premium gasoline with an octane rating. AKI of 91,
or above. AKI (ANTI KNOCK INDEX) is an average of the Research Octane Number, RON, and the Motor Octane
Number, MON. (RON + MON/2).
The minimum octane requirement is AKI 87 (RON 91).
pg. 61 Fuel requirements
Fuel Formulations
ProCarManuals.com

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.
Carbon Monoxide - Important Warning
Carbon monoxide is a poisonous, colorless, and odorless gas. It is present in all exhaust gases. If you ever smell
exhaust fumes inside the vehicle, make sure the passenger compartment is ventilated, and immediately return the
vehicle to your retailer for correction.
Gasoline containing alcohol and ethers
"Oxygenated fuels"
Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols or ethers. In some areas, state or
local laws require that the service pump be marked indicating use of alcohols or ethers. However, there are areas in
which the pumps are unmarked. If you are not sure whether there is alcohol or ethers in the gasoline you buy, check
with the service station operator. To meet seasonal air quality standards, some areas require the use of "oxygenated"
fuel.
Volvo allows the use of the following "oxygenated" fuels; however, the octane ratings listed on this page must still be
met.
Alcohol — Ethanol
Fuels containing up to 10% ethanol by volume may be used.
Ethanol may also be referred to as Ethyl alcohol, or "Gasohol".
Ethers — MTBE
Fuels containing up to 15% MTBE may be used.

Fuel filler door control on driver's door
Refueling
The fuel tank holds approximately 18 US gal. (68 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
The fuel filler door (on the right rear fender) is locked and must be popped open using the control on the driver's door.
Open fuel filler cap slowly during hot weather conditions
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. 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 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.
pg. 63 Driving economy
Economical driving conserves natural resources
Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stops and adjusting the speed of
your vehicle to immediate traffic conditions. Observe the following rules:
Bring the engine to normal operating temperature as soon as possible by driving with a light foot on the accelerator
