1998 VOLVO C70 Owners Manual

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
.

WARNING! Packages on the rear window shelf can obscure vision and may become dangerous projectiles in the
event of a sudden stop or an accident.
pg. 41 Sun roof (option)

Sliding sun roof
Electrically-operated sun roof
The switch for operating the sun roof is located on the instrument panel. The starting (ignition) key must first be turned
to the drive position (position II). The sun roof is also equipped with a one -touch, AUTO-open function.
AUTO-open: Press the lower section of the switch once to automatically open the sun roof. The AUTO-open
function can be stopped at any time by pressing the switch.
To close the sun roof: Depress the upper section of the switch until the sun roof has closed completely.

Sun visor
To open the rear edge of the sun roof (ventilation position) : With the sun roof closed, depress the upper section
of the switch. To close, depress the lower section of the switch until the sun roof has closed completely.
To slide open the sun roof: Depress the lower section of the switch until the sun roof has opened to the position
you prefer or hold the switch until the sun roof reaches the "comfort position"*. Depress the lower section of the
switch again to open the sun roof completely.
* A position where the sun roof is not quite fully open. This position helps alleviate "rumbling" wind noise.

Sun visor: The sun roof also features a sliding sun visor. The visor slides back automatically when the sun roof is
opened and also slides back slightly when the sun roof is opened to the ventilation position. The visor must be closed
manually.
CAUTION: Do not close the sun visor when the sun roof is in the ventilation position as this could damage the
mechanism.
NOTE:
The electrically -operated sun roof has an overload protecting circuit breaker (fuse no. 37) which is activated when an
object blocks the sun roof. Should this occur, remove the object and wait 20 seconds for the circuit breaker to reset.
The sun roof should then function normally. Also check fuse no. 35.
WARNING! The sun roof must never be obstructed in any way when in operation.
pg. 42 Keys, doors and locks
Master key
This key operates all locks (ignition switch/steering wheel lock, driver's door, trunk and glove compartment).
Service key
This key operates the driver's door and the ignition switch/steering wheel lock.
NOTE:
As an added anti-theft measure, new keys have been developed which may take slightly longer to copy or replace if
the original keys are misplaced. Duplicate keys may be ordered from your Volvo retailer.
The key number codes are stamped on a separate tag supplied with the keys. This tag should be separated from the
key ring and kept in a safe place.
Doors and locks
Your car is equipped with a central locking system.
The key, used on the driver's door, the remote control, or central locking button, will lock/unlock both doors, and the
trunk.
Turn the key once to unlock the driver's door only.
Turn the key again (within 10 seconds) to unlock both doors and the trunk.
One turn with the key towards lock in the drivers door locks both doors and the trunk.
Use the switch on the front door armrests to lock/unlock the car from the inside.
ProCarManuals.com

Check the action of the buttons on the other door to verify its function (lock/unlock).
WARNING! The doors should not be locked while driving. In case of an accident, this may hinder rapid access to
the occupants of the vehicle.
NOTE: If a door is not closed completely, the courtesy lights will stay on and a chime will sound until the door is
closed.

pg. 56 Break-in period, Fuel requirements
A new car should be broken -in

Refrain from utilizing your car's full driving potential during the first 1,200 miles (2,000 km) including the "kick -
down" function (automatic transmission).
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 114
.
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.

Manual transmission
The following speeds should not be exceeded during the break-in period: Up to 600 miles
(1000 km)600 - 1,200 miles
(1000 - 2000 km)
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)
5th gear/overdrive 80 mph (130 km/h)95 mph (150 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.
pg. 57 Fuel requirements, Refueling
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
