engine VOLVO C70 2000 User Guide

Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stops and adjusting the speed of
your vehicle to immediate traffic conditions. Observe the following rules:
· Bring the engine to normal operating temperature as soon as possible by driving with a light foot on the accelerator
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 roof racks, ski racks, etc., 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:
· Worn or dirty spark plugs
· Incorrect spark plug gap
· 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.

Starting and stopping
ProCarManuals.com

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.
* 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.
4. To release the gear selector from the (P)ark position (automatic transmission), the ignition key must be in position II
and the brake pedal must be depressed. See page 97 for instructions on manually releasing the SHIFTLOCK
system.
Do not race a cold engine immediately after starting. Oil flow may not reach some lubrication points fast enough to
prevent engine damage.
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! Toorapid 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!
Hydraulic valve lifters
This engine features hydraulic valve lifters which means that valve clearance is adjusted automatically. It is possible
that the valve lifters will produce a ticking sound for the first few seconds after the engine is started, while the oil
pressure is increasing.
If the car has not been used for a long period of time, this ticking sound may last for up to 15 minutes. This is entirely
normal.
Do not exceed 3000 rpm until the ticking sound disappears.

Washing the car
· The car should be washed at regular intervals since dirt, dust, insects and tar spots adhere to the paint and may cause
damage.
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 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 vehicle than 13" (30
cm). Do not spray 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.
