Oxygen Sensor

On the B230F engines, the oxygen sensor (Lambda-sond) is electrically \
heated. The use of a PTC
(Positive Temperature Coefficient) element to heat the Lambda-sond ens\
ures a shorter warm up time
and continuous operation at its working temperature.
This type of Lambda-sond does not require periodic replacement.

Catalytic Converter

This is a supplementary device in the exhaust system, designed to reduce\
exhaust emissions.
This device is mainly a container with a ceramic material insert, design\
ed to let the exhaust gases pass
through channels in the insert. The channel walls are covered by a thin \
layer of platinum and rhodium.
These metals act as catalysts, permitting a chemical action to occur wit\
hout actually taking part in it.
The carbon monoxide content will increase if the Catalytic Converter is \
damaged.
CAUTION:
Vehicles with Catalytic Converter must use unleaded fuel only. Otherwise\
the Catalytic Converter will
become damaged and ineffective.

Torque catalytic converter mounting bolts

The Catalytic Converter mounting bolts should be re-torqued at the 600-1\
,200 mile (1000-2000) km
inspection.

Check coolant level

The cooling system must be filled with coolant and not leak to operate a\
t maximum efficiency. Check
the coolant level whenever you refuel. The level should be between the "\
Max"' and "Min" marks on the
expansion tank. The check should be made with particular thoroughness wh\
en the engine is new or the
cooling system has been drained.
Do not remove the filler cap other than for topping up with coolant. Fre\
quent removal may prevent
coolant circulation between the engine and the expansion tank during eng\
ine warm up and cooling.
CAUTION
The cooling system must always be kept filled to the correct level.
If it is not kept filled, there can be high local temperatures in the en\
gine which could result in
damage.

Top up with coolant

Top up with coolant by filling the expansion tank when level is at the "\
Min" mark. Use a mixture of 50
percent Volvo Type C coolant and 50 percent water all the year round. To\
p up to the "Max" mark.
If the engine is warm, and you are going to add coolant, unscrew the cap\
slowly in order to allow any
excess pressure to escape.
Note: Do not add water only. Water by itself reduces the rust protective\
and anti-freeze qualities of the
coolant and has a lower boiling point. It can also cause damage to the c\
ooling system if it should
freeze.
See 'Specifications' section of the manual for type of coolant recommend\
ed.

Checking and correcting tire pressure

Check the tire pressure when refueling. The tire pressure should only be\
corrected when the tires are
cold. With warm tires, correct only when the pressure is too low. The ti\
re temperature (and, thus,
pressure) rises after driving just a few miles.
Warning: Improperly inflated tires will reduce tire life, adversely affe\
ct vehicle handling and can
possibly lead to failure resulting in loss of vehicle control without pr\
ior warning.

Vehicle Loading

The tires on your Volvo will perform to specifications at all normal loa\
ds when inflated as
recommended on the tire information label located on the rear facing sid\
e of the right front door. This
label lists both tire and vehicle design limits.
Do not load your car beyond the load limits indicated.

Tire Pressure Label

The tire pressure label is located on the rear facing side of the right \
front door.
See section titled ''Specifications'' and Consumer Information Booklet f\
or complete tire pressure
information.

Wear indicator

The tires have a so-called "wear indicator in the form of a number of na\
rrow strips running across or
parallel to the tread. When approx 1/16 " (1.5 mm) is left on the trea\
d, these strips show up and indicate
the tire should be replaced.
Tires with less than 1/16" (1.5 mm) tread have a very poor grip in rai\
n or snow.

General

When replacing worn tires, it is recommended that the tire be identical \
in type (radial) and size as the
one being replaced. Using a tire of the same make (manufacturer) will \
prevent altering the driving
characteristics of the vehicle.

How to improve tire economy

l Maintain correct tire pressure
l Drive smoothly: avoid fast starts, hard braking and tire screeching.

cloth.
CAUTION: It is particularly important to wash the car frequently in the \
winter time, to prevent
corrosion, when salt has been used on the roads. Also wash off the dirt \
on the underside (Wheel
housings and fenders etc.)
WARNING: When the car is driven immediately after being washed, carefull\
y apply the brakes
several times in order to remove any moisture from the brake linings.
pg. 87 Washing, Cleaning, Anti-rust treatment
Automatic washing - simple and quick

An automatic wash is a simple and quick way to clean your car, but it is\
worth remembering that it can
never be as thorough as when you yourself go over the car with sponge an\
d water. Keeping the
underbody clean is most important, especially in the winter. Some automa\
tic washers do not have
facilities for washing the underbody.
Before driving into an automatic wash, make sure that side view mirrors,\
auxiliary lamps, etc., are
secure, otherwise there is risk of the machine dislodging them. You shou\
ld also lower the antenna.
We recommend that you do not wash your car in an automatic wash during t\
he first six months (because
the paint will not have hardened sufficiently).

Bird droppings /Tree sap

Remove from paintwork as soon as possible. Otherwise the finish may be p\
ermanently damaged.

Chromed parts

Chromium-plated and anodized parts should be washed with clean water as \
soon as they become dirty.
This is particularly important if you drive on gravel roads or on roads \
where salt is used during the
winter. After the car has been washed, apply wax or an anti-rust prepara\
tion.
Stains on chrome trim can be removed with commercially available chrome \
cleaner. Do not use abrasive
compounds or steel wool.

Polishing (waxing)

Normally, polishing is not required during the first year after delivery\
. Waxing may be beneficial.
Before applying polish or wax the car must be washed and dried. Tar spot\
s can be removed with
kerosene or tar remover. Difficult spots may require a fine rubbing comp\
ound.
After polishing use liquid or paste wax.
Several commercially available products contain both polish and wax. Wax\
ing alone does not substitute
for polishing of a dull surface.
A wide range of polymer based car waxes can be purchased today. The waxe\
s are easy to use and
produce a long lasting high gloss finish which protects the bodywork aga\
inst oxidation, road dirt and
fading.

Cleaning the upholstery

Generally the fabric can be cleaned with soapy water or a detergent. For\
more difficult spots caused by
oil, ice cream, shoe polish, grease, etc., use a stain remover.
The plastic in the upholstery can be washed.
To clean leather upholstery , use soft cloth and mild soap solution, for\
instance common bath soap.
For more difficult spots, consult an expert for the choice of cleaning a\
gent.
On no account must gasoline, naphtha or similar cleaning agents be used \
on the plastic or the leather
since these can cause damage.
When aging, leather changes appearance, but the typical texture remains.\
To preserve smoothness and
appearance, it is recommended to treat the leather with a special leathe\
r preservative after one or two
years of use.

Cleaning the seat belts

Clean only with luke warm water and mild soap solution.
WARNING! Do not use cleaning solvents to clean the seat
belts.

During the winter, multigrade oil 10W-30 should be used in the engine. \
The viscosity of the engine oil is important. Oil with low viscosity (t\
hinner oil) improves cold-weather
starting as well as decreasing fuel consumption while the engine is warm\
ing up. To avoid difficult cold
start conditions (during extreme winter weather), use of 5W-30 oil, pa\
rticularly the synthetic type, is
recommended.
Be sure to use good quality oil but do not use this cold-weather oil for\
hard driving or in warm weather.
See section "Engine oil" for more information.

Electrical system

The electrical system is subject to greater stresses during the winter. \
Lighting and starter motor are used
more often. The battery capacity is reduced at low air temperature. The \
state of charge must be checked
more frequently, and if necessary the battery should be recharged. The b\
attery can freeze if the state of
charge is too low.

Windshield washers

Anti-freeze washer fluid should also be added to the washer fluid contai\
ner for the windshield and rear
window (tailgate, wagon model) washer.
This is particularly important during the winter because the windshield \
frequently becomes dirty and is
often splashed with water which freezes rapidly. This may necessitate th\
e frequent use of the windshield
washer and wipers. Your Volvo dealer can supply you with suitable anti-f\
reeze for this purpose. Suitable
mixtures of anti-freeze and water are:
Down to +14 ° F (-10 ° C) 1 part anti-freeze 4 parts water.
Down to + 7 ° F (-14 ° C) 1 part anti-freeze 3 parts water.
Down to 0 ° F (-18 ° C) 1 part anti-freeze 2 parts water.
Down to -18 ° F (-28 ° C) 1 part anti-freeze 1 part water.
Use Volvo Teflon lock spray or grease in the locks. They can be purchase\
d from your Volvo dealer
Note: Avoid the use of de-icing sprays as they can cause damage to the
locks.
