1998 VOLVO C70 check engine light

The ABS system in your car performs a self -diagnostic test when the vehicle first reaches the speed of approximately
12 mph (20 km/h). The brake pedal will pulsate several times and a sound may be audible from the ABS control
module. This is normal.
Fuel tank cover
The fuel tank cover is locked and must be popped open using the control on the driver's door.
The pages in this section provide detailed descriptions of the vehicle's instruments and controls. Note that vehicles may
be equipped differently, depending on special legal requirements.
pg. 16 Instruments
1 Fuel gauge
The fuel tank holds approximately 18.4 US gals. (70 liters). When the warning light comes on there is approximately
1.8 US gals. (8 liters) of fuel remaining. See "Refueling" for further information.

2 Temperature gauge
Do not drive the car with the pointer in the red range. The pointer should be approximately midway on the gauge
face when driving. If the pointer approaches the red range repeatedly, check coolant level. See page 130
.
3 Speedometer
4 Clock, ambient temperature sensor, trip computer (certain models)
5 Odometer
6 Trip odometer
Used for measuring shorter distances. The last digit indicates 1/10 mile/kilometer.
7 Trip odometer reset button
8 Tachometer
Reads thousands of engine rpm. The engine should not be operated in red range. The highest permitted constant
engine speed is 6,200 rpm.

1st gear 20 mph (30 km/h)25 mph (40 km/h)
2nd gear 30 mph (50 km/h)40 mph (70 km/h)
3rd gear 45 mph (80 km/h)65 mph (100 km/h)
4th gear 70 mph (110 km/h)80 mph (130 km/h)

Posted speed limits should not be exceeded.
Deposit control gasoline (detergent additives)
Volvo recommends the use of gasoline containing deposit control additives. These additives have shown to be efficient
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 labeled "UNLEADED". Only these pumps have nozzles which fit
your car's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labeled "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).
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 alcohol 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 restrictions, some states require the use of "oxygenated" fuel in certain areas.
Volvo allows the use of the following "oxygenated fuels; however, the octane ratings listed on this page must still be
met.
Alcohol — Ethanol
