A new car should be broken-in!
Refrain from utilizing your car's full driving
potential, e.g. full-throttle acceleration, during the
first 1,200 miles (2,000 km).
Automatic transmission
Do not use "kick-down" during the first 1,200
miles (2,000 km).
NOTE - ENGINE OIL:
Although some oil consumption 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 108.
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 refuelled is one of the most important items
you can perform to help keep your car in good
running order.
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.

Chapter 8 - (cont.)Engine oil
pg. 108
Checking the oil level
The oil level should be checked every
time the car is refuelled. This is
especially important during the engine
break-in period (up to the first service).
CAUTION: Not checking the oil level
regularly can result in serious engine
damage if the oil becomes too low.
Be sure the oil level is maintained between
the upper and lower marks on the dipstick.
Low oil level can cause internal damage to
the engine and over-filling can result in
high oil consumption. The distance
between the dipstick marks represents
approx. 1 US qt (1 liter) of oil. Before
checking the oil level after the car has been
driven, park the car on a level surface and
wait at least 5 minutes after the engine has
been switched off. The oil level should be
halfway between the MIN and MAX
marks.
If the oil is checked before the car is driven
(engine completely cold) the oil level
should be at the MAX mark.
NOTE: The engine must be stopped when
checking the oil.
Draining the oil
Drain the oil after driving while it is still
warm.
WARNING! The oil may be very
hot.
To add or change engine oil
Add oil of the same kind as already used.
Capacity (including filter): 5.9 US qts = 5.75 liters
Changing oil filter
Replace the oil filter at every oil change
WARNING! Oil spilled on a hot exhaust pipe
constitutes a fire risk.
