oil VOLVO C70 2004 Owners Manual

The manual is structured so that it can be used for reference. For this reason, it should be kept in the car for
ready access.
Do not export your Volvo to another country before investigating that country's applicable safety and exhaust
emission requirements. In some cases it may be difficult or impossible to comply with these requirements.
Modifications to the emission control system(s) may render your Volvo not certifiable for legal operation in the
U.S., Canada and other countries.
All information, illustrations and specifications contained in this manual are based on the latest product
information available at the time of publication. Please note that some vehicles may be equipped differently,
depending on special legal requirements and that optional equipment described in this manual may not be
available in all markets.
Volvo reserves the right to make model changes at any time, or to change specifications or design, without
notice and without incurring obligation.
CAUTION: Certain models have reduced ground clearance due to the design of the front spoiler. Please observe
caution when e.g., driving onto garage hoists, through drifted snow or when other road debris is encountered, or when
parking near curbs.
Warning!
If your vehicle is involved in an accident, unseen damage may affect your vehicle's driveability and safety.
Shiftlock (automatic transmission only)
When your car is parked, the gear selector is locked in the (P)ark position. To release the selector from this position,
turn the ignition key to position II (or start the engine), depress the brake pedal, press the button on the front side of the
gear selector and move the selector from (P)ark.
If it is necessary to manually override the shiftlock system:
Turn the starting (ignition) key to position I
Press firmly on the "SHIFTLOCK OVERRIDE" button located to the right of the base of the gear selector
While holding the override button down, press the button on the front of the gear selector
Move the selector from the ( P)ark position.
Keylock (automatic transmission only)
When you switch off the ignition, the gear selector must be in the (P)ark position before the starting (ignition) key can
be removed from the ignition switch.
Clutch interlock (manual transmission only)
The clutch must be fully depressed before you can start you car. If the clutch is not depressed, it will not be possible to
start the engine.
Anti-lock Brake System (ABS)
The ABS system in your car performs a self -diagnostic test when the vehicle first reaches the speed of approximately
ProCarManuals.com

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 (see illustration on page
14).
Volvo and the environment
Volvo is committed to the well being of our customers. As a natural part of this commitment, we care about the
environment in which we all live. Caring for the environment means an everyday involvement in reducing our
environmental impact.
Volvo's environmental activities are based on a holistic view, which means we consider the overall environmental
impact of a product throughout its complete life cycle. In this context, design, production, product use, and recycling
are all important considerations.
In production, Volvo has partly or completely phased out several chemicals including freons, lead chromates,
naphtanates, asbestos, mercury and cadmium; and reduced the amount of chemicals used in our plants 50% since 1991.
In use, Volvo was the first in the world to introduce into production a three-way catalytic converter with a Lambda
sond, now called oxygen sensor, in 1976. The current version of this highly efficient system reduces emissions of
harmful substances (CO, HC, NOx) from the exhaust pipe by approximately 95% and the search to eliminate the
remaining emissions continues. Volvo is the only automobile manufacturer to offer CFC-free retrofit kits for the air
conditioning system for all models as far back as the M/Y 1975 240. Advanced electronic engine controls, refined
purification systems and cleaner fuels are bringing us closer to our goal.
After Volvo cars and parts have fulfilled their use, recycling is the next critical step in completing the life cycle. The
metal content is about 75% of the total weight of a car, which makes the car among the most recycled industrial
products. In order to have efficient and well controlled recycling, many Volvo variants have printed dismantling
manuals, indicating the weight and material of individual components. For Volvo, all homogeneous plastic parts
weighing more than 1.7 oz. (50 grams) are marked with international symbols that indicate how the component is to be
sorted for recycling.
In addition to continuous environmental refinement of conventional gasoline-powered internal combustion engines,
Volvo is actively looking at advanced technology alternative-fuel vehicles.
When you drive a Volvo, you become our partner in the work to lessen the car's impact on the environment.
To reduce your vehicle's environmental impact, you can:
Maintain proper air pressure in your tires. Tests have shown decreased fuel economy with improperly inflated tires
Follow the recommended maintenance schedule in your Warranty and Service Records Information booklet.
Drive at a constant speed
See an authorized Volvo retailer as soon as possible for inspection if the check engine (malfunction indicator) lamp
illuminates, or stays on after the vehicle has started
Properly dispose of any vehicle related waste such as used motor oil, used batteries, brake pads, etc.
When cleaning your car, use Volvo's own car care products, all of which have systematically been adapted to the
environment

pg. 18 Warning lights
The warning lights described on pages 18 and 19 should never stay on when driving
When the ignition key is turned on and before the engine starts, all of the warning lights should go on to test the
function of the bulbs. Should a light not go off after the engine has started, the system indicated should be inspected.
However, the parking brake reminder light will not go off until the parking brake has been fully released.
Malfunction indicator lamp
On-Board Diagnostic II (OBDII): As you drive, a computer called "OBDII" monitors your car's engine, transmission,
electrical and emission systems. The CHECK ENGINE light will light up if the computer senses a condition that
potentially may need correcting. When this happens, please have your car checked by a Volvo retailer as soon as
possible.
A CHECK ENGINE light may have many causes. Sometimes, you may not notice a change in your car's behavior.
Even so, an uncorrected condition could hurt fuel economy, emission cleanliness, and driveability. Extended driving
without correcting the cause could even damage other components in your car.
NOTE : 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.
Canadian models are equipped with this warning light:
Oil pressure warning light
If the light comes on while driving, stop the car and then stop the engine immediately and check the engine oil
level . See page 116.
If the light stays on after restart, have the car towed to the nearest authorized Volvo retailer. After
hard driving, the light may come on occasionally when the engine is idling. This is normal, provided it goes off when
the engine speed is increased.
Roll Over Protection System (ROPS)
If the warning lamp remains on after the engine has started or comes on while you are driving, the ROPS self -
diagnostic system has detected a fault. The car should be driven to an authorized Volvo retailer as soon as possible for
inspection.
Please refer to page 10
for more information on the ROPS system.
Brake failure warning light
If the light comes on while driving or braking, stop immediately, open the hood and check the brake fluid level

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.

pedal for the first few minutes of operation. A cold engine uses more fuel and is subject to increased wear.
Whenever possible, avoid using the car for driving short distances. This does not allow the engine to reach normal
operating temperature.
Drive carefully and avoid rapid acceleration and hard braking.
Do not exceed speed limit.
Avoid carrying unnecessary items (extra load) in the car.
Maintain correct tire pressure. Check tire pressure regularly (check when tires are cold).
Remove snow tires when threat of snow or ice has ended.
Note that trunk-mounted luggage racks increase air resistance and thereby fuel consumption.
Avoid using automatic transmission kickdown feature unless necessary.
Avoid using the air conditioning when it is not required. When engaged, the air conditioner's compressor places an
additional load on the engine. However, please note that fuel consumption is lower with the air conditioning on than it
is when driving with the air conditioning switched off and the windows down.
If your car is equipped with the optional Trip Computer, utilizing the fuel consumption modes can help you "learn"
how to drive more economically.
Other factors which decrease gas mileage are:
Dirty air cleaner
Dirty engine oil and clogged oil filter
Dragging brakes
Incorrect front end alignment
Some of the above mentioned items and others are checked at the standard Maintenance Service intervals.
NOTE : (D)rive or 5th gear (manual transmissions) should be used as often as possible to help improve fuel economy.
pg. 64 Starting the Engine
Starting and stopping
1. Fasten the seat belt.
WARNING!
Before starting, check that the seat, steering wheel and mirrors are adjusted properly. Make sure the brake pedal can
be depressed completely. Move the seat closer if necessary. Refer to section "front seats".
2. Apply the parking brake, if not already set. The gear selector (automatic transmission) is locked in the (P)ark
position (SHIFT LOCK).
Manual transmission: the clutch must be fully depressed.
3. Without touching the accelerator pedal, turn the ignition key to the starting position*. Allow the starter to operate
for up to 10 seconds. Release the key as soon as the engine starts. If the engine fails to start, repeat step 3.
For cold starts at altitudes above 6000 ft (1800 meters), depress the accelerator pedal halfway and turn the key to the
starting position. Release the pedal slowly when the engine starts.
4. To release the gear selector from the (P)ark position (automatic transmission), the ignition key must be in position II
ProCarManuals.com

and the brake pedal must be depressed. See page 101 for instructions on manually releasing the SHIFTLOCK
system.
NOTE: (Automatic transmission only)
Your car is equipped with a KEYLOCK system. When the engine is switched off, the gear selector must be in the
( P )ark position before the starting key can be removed from the ignition switch.
5. Select the desired gear. The gear engages after a slight delay (automatic transmission) which is especially noticeable
when selecting R.
CAUTION : (Automatic transmission only)
The engine should be idling; never accelerate until after you feel the gear engage! Too-rapid acceleration immediately
after selecting a gear will cause harsh engagement and premature transmission wear.
NOTE : Selecting P or N (automatic transmission) when idling at a standstill for prolonged periods of time will help
prevent overheating of transmission oil.
WARNING!
Always place the gear selector (automatic transmission) in Park and apply the parking brake before leaving the
vehicle. Never leave the car unattended with the engine running.
Always open the garage doors fully before starting the engine inside a garage to ensure adequate ventilation. The
exhaust gases contain carbon monoxide, which is invisible and odorless but very poisonous.
CAUTION: Never race the engine immediately after starting. Oil flow may not reach some lubricating points fast
enough to prevent engine damage.
Do not race the engine just prior to switching off!
* If the key is left in the Drive position (position II) for more than 30 seconds, it must be turned to position 0 and then
turned to the Start position (position III) again in order to start the car. See page 21
for ignition key positions.

NOTE: It is particularly important to wash the car frequently in the wintertime to prevent corrosion, when salt has
been used on the roads.
When washing the car, do not expose it to direct sunlight. Use lukewarm water to soften the dirt before you wash
with a sponge, and plenty of water, to avoid scratching.
Bird droppings: Remove from paintwork and the convertible top as soon as possible. Otherwise the finish may be
permanently damaged.
A detergent can be used to facilitate the softening of dirt and oil.
A water-soluble grease solvent may be used in cases of sticky dirt. However, use a wash place equipped with a
drainage separator.
Dry the car with a clean chamois and remember to clean the drain holes in the doors and rocker panels *.
The power radio antenna must be dried after washing.
Tar spots can be removed with kerosene or tar remover after the car has been washed.
A stiff-bristle brush and lukewarm soapy water can be used to clean the wiper blades. Frequent cleaning improves
visibility considerably.
Wash off the dirt from the underside (wheel housings, fenders, etc.).
In areas of high industrial fallout, more frequent washing is recommended.
CAUTION: During high pressure washing, the spray mouthpiece must never be closer to the painted surfaces of the
vehicle than 13" (30 cm). Do not spray directly into the locks.
When washing or steam cleaning the engine, avoid spraying water or steam directly on the electrical components or
toward the rear side of the engine.
After cleaning the engine, the spark plug wells should be inspected for water and blown dry if necessary.
Suitable detergents
Special car washing detergents should be used. A suitable mixture is about 2.5 fl. oz. (8.5 cl) of detergent to 2.6 US
gal. (10 liters) of warm water. After washing with a detergent the car should be well rinsed with clean water.
WARNING!
When the car is driven immediately after being washed, apply the brakes several times in order to remove any
moisture from the brake linings.
Engine cleaning agents should not be used when the engine is warm. This constitutes a fire risk.
Volvo offers an environmentally friendly Car Care Kit, containing waxing, washing, and degreasing agents.
NOTE: When washing the car, remember to remove dirt from the drain holes in the doors and sills. Bumpers: Wash
the bumpers with the same cleaning agent used on the rest of the car. Never clean the bumpers with gasoline or paint
thinner. Difficult spots can be removed with denatured alcohol. To avoid scratches, do not dry the bumpers with paper.
