The gauge indicates the temperature of the engine cooling system. If the\
temperature is abnormally high and the
needle enters the red zone, a message is shown in the display. Bear in m\
ind that auxiliary lamps in front of the air
intake reduce the cooling capacity at high outside temperatures and high\
engine loads.
15.Indicator and warning symbols
Function check
The indicator and warning symbols
1 light up when you turn the ignition key to the driving position (posit\
ion II)
before starting. This shows that the symbols are functioning.
When the engine starts, all symbols go out. If the engine is not started\
within 5 seconds, all of the symbols except
CHECK ENGINE and will go out. Certain symbols may not have their functio\
ns illustrated, depending on the car's
equipment.
The PARK BRAKE symbol will not go out until the parking brake has been r\
eleased.
Symbols in the center of the instrument panel
Warning symbol
The red warning symbol lights up to indicate a fault that could affect t\
he car's drivability. A text explaining the nature
of the fault will also be shown in the information display. The symbol a\
nd accompanying text will remain on until the
fault has been corrected. This symbol may also light up in combination w\
ith other indicator or warning symbols.
1On certain engines, the symbol for low oil pressure is not used. Instead\
, a text warning is provided in the information display,

CAUTION
l Engine damage will occur if water is drawn into the air cleaner.
l If the vehicle is driven through water deeper than 9 in (25 cm), water\
may enter the differential and
the transmission. This reduces the oil's lubricating capacity and may sh\
orten the service life of these
components.
l Do not allow the vehicle to stand in water up to the door sills longer t\
han absolutely necessary. This
could result in electrical malfunctions.
l If the engine has been stopped while the car is in water, do not attempt\
to restart the engine. Have the
car towed out of the water.
Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, t\
he following advice is worth
noting:
l Make sure that the engine coolant contains 50 percent antifreeze. Any ot\
her mixture will reduce freeze
protection. This gives protection against freezing down to - 31°F (-\
35°C). See section "Coolant". The use
of "recycled" antifreeze is not approved by Volvo. Different types of an\
tifreeze must not be mixed.
l Volvo recommends using only genuine Volvo antifreeze in your vehicle's r\
adiator. Your Volvo retailer
stocks plenty of Volvo engine coolant to help protect your vehicle durin\
g cold weather.
l Try to keep the fuel tank well filled - this prevents the formation of c\
ondensation in the tank. In
addition, in extremely cold weather conditions it is worthwhile to add f\
uel line de-icer before refueling.
l 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. For winter use, 5W-30
oil, particularly the synthetic type
1, is recommended. Be sure to use good quality oil but do not use cold-
weather oil for hard driving or in warm weather. See
page 239 for more information.
l The load placed on the battery is greater during the winter since the wi\
ndshield wipers, lighting, etc. are
used more often. Moreover, the capacity of the battery decreases as the \
temperature drops. In very cold
weather, a poorly charged battery can freeze and be damaged. It is there\
fore advisable to check the state
of
1Synthetic oil is not used when the oil is changed at the normal maintena\
nce intervals except at owner request and
at additional charge. Please consult your Volvo retailer.

General information
charge more frequently and spray an antirust oil on the battery posts.
l Volvo recommends the use of snow tires on all four wheels for winter dri\
ving - see the chapter "Wheels
and tires."
