2012 VOLVO C70 check engine

09 Maintenance and servicing
Engine oil 09
220
CAUTION
•Not checking the oil level regularly can
result in serious engine damage if the oil
level becomes too low.
•Oil that is lower than the specified qual-
ity can damage the engine.
•Always add oil of the same type and
viscosity as already used.
•Never fill oil above the MAX mark. This
could cause an increase in oil consump-
tion.
WARNING
Do not allow oil to spill onto or come into
contact with hot exhaust pipe surfaces
NOTE
Volvo uses different systems to indicate a
low oil level or pressure. Some models have
an oil pressure sensor, in which case a
warning symbol (see page 58) is used to
indicate low oil pressure. Other models have
an oil level sensor, in which case the driver
is alerted by the warning symbol in the cen-
ter of the instrument panel and a text in the
information display. Some models use both
systems. Contact an authorized Volvo
retailer for more information.

221 Washer fluid
Washer fluid reservoir
The washer fluid reservoir is located in the
engine compartment and holds approximately
4.2 US qts (4 liters). During cold weather, the
reservoir should be filled with windshield
washer solvent containing antifreeze.
Coolant
Coolant reservoir
Normally, the coolant does not need to be
changed. If the system must be drained, con-
sult a trained and qualified Volvo service tech-
nician.
CAUTION
•If necessary, top up the cooling system
with Volvo Genuine Coolant/Antifreeze
only (a 50/50 mix of water and anti-
freeze).
•Different types of antifreeze/coolant
may not be mixed.
•If the cooling system is drained, it
should be flushed with clean water or
premixed anti-freeze before it is refilled
with the correct mixture of water/anti-
freeze.
•The cooling system must always be
kept filled to the correct level, and the
level must be between the MIN and
MAX marks. If it is not kept filled, there
can be high local temperatures in the
engine which could result in damage.
Check coolant regularly!
•Do not top up with water only. This
reduces the rust-protective and anti-
freeze qualities of the coolant and has a
lower boiling point. It can also cause
damage to the cooling system if it
should freeze.
•Do not use chlorinated tap water in the
vehicle's cooling system.

WARNING
•Never remove the expansion tank cap
while the engine is warm. Wait until the
engine cools.
•If it is necessary to top off the coolant
when the engine is warm, unscrew the
expansion tank cap slowly so that the
overpressure dissipates.
Brake fluid
Brake fluid reservoir
The brake fluid should always be between the
MIN and MAX marks on the side of the reser-
voir. Check, without removing the cap, that
there is sufficient fluid in the reservoir.Fluid type: DOT 4+ boiling point >536 °F
(>280 °C), P/N 9437433
Replace: The fluid should be replaced accord-
ing to the intervals specified in the Warranty
and Service Records Information booklet.
When driving under extremely hard conditions
(mountain driving, etc), it may be necessary to
replace the fluid more often. Consult your
Volvo retailer. Always entrust brake fluid
changing to a trained and qualified Volvo serv-
ice technician.
WARNING
•If the fluid level is below the MIN mark
in the reservoir or if a brake-related
message is shown in the information
display: DO NOT DRIVE. Have the car
towed to a trained and qualified Volvo
service technician and have the brake
system inspected.
•Dot 4+ should never be mixed with any
other type of brake fluid.
Power steering fluid
The fluid level is checked at each service inter-
val.
Fluid type: Volvo power steering fluid or equiv-
alent.
Replace: No fluid change required.
WARNING
If a problem should occur in the power
steering system or if the vehicle has no elec-
trical current and must be towed, it is still
possible to steer the vehicle. However, keep
in mind that greater effort will be required to
turn the steering wheel.

09 Maintenance and servicing
Battery 09
224
Battery maintenance
Driving habits and conditions, climate, the
number of starts, etc., all affect the service life
and function of the battery. In order for your
battery to perform satisfactorily, keep the fol-
lowing in mind:
Check the fluid level in each cell in the battery
every 24 months or every 15,000
1 miles
(24,000 km), whichever is sooner.
•Use a screw driver to open the caps or
cover and a flashlight to inspect the level.
•If necessary, add distilled water. The level
should never be above the indicator.
•The fluid level should be checked if the
battery has been recharged.
•After inspection, be sure the cap over each
battery cell or the cover is securely in
place.
•Check that the battery cables are correctly
connected and properly tightened.
•Never disconnect the battery when the
engine is running, or when the key is in the
ignition. This could damage the vehicle's
electrical system.
•The battery should be disconnected from
the vehicle when a battery charger is used
directly on the battery.
•To help keep the battery in good condition,
the vehicle should be driven for at least 15
minutes a week or connected to a charger
with an automatic charging function.
•If the battery is fully discharged a number
of times, this may shorten its service life.
Keeping the battery fully charged helps
prolong its service life.
•The service life of a battery is affected by
factors such as driving conditions and cli-
mate. Extreme cold may also further
decrease the battery’s starting capacity.
•Because the battery’s starting capacity
decreases with time, it may be necessary
to recharge it if the vehicle is not driven for
an extended period of time or if the vehicle
is usually only driven short distances.
