The air conditioning is momentarily disengaged during full-throttle acce\
leration.
Climate control maintenance
Special tools and equipment are required to maintain and carry out repai\
rs on the climate system. Work of this type
should only be done by a trained and qualified Volvo service technician.\
Refrigerant
Volvo cares about the environment. The air conditioning system in your v\
ehicle contains a CFC-free refrigerant -
R134a (HFC134a). This substance will not deplete the ozone layer. The \
system contains 1.5 lbs (700 g) R134a and
uses PAG oil.
Climate system blower
The climate system blower will be automatically switched off when the en\
gine is not running (even if the ignition
key is in position I or II) to avoid unnecessary battery drain. To acti\
vate the blower, turn the control to the desired
setting.
Passenger compartment blower
Approximately 50 minutes after the ignition is turned off, the blower ma\
y come on automatically, and run for seven
minutes, to remove condensation in the A/C evaporator.

tighten the cover. Turn a quarter turn (90 degrees). See illustration.\

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 typ\
es of antifreeze 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 protect your vehicle d\
uring cold weather.
l Try to keep the fuel tank well filled - this prevents the formation of condensation 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 (thinner oil) improves cold-
weather starting as well as decreasing fuel consumption while the engine\
is warming 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 section "E\
ngine oil" for more information.
l The load placed on the battery is greater during the winter since the windshield 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 \
therefore advisable to check the
state of 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 driving - see section "Wheels
and tires."
l To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze (see

surfaces.
Certain models are equipped with "all-season" tires, which provide a som\
ewhat higher degree of road
holding on slippery surfaces than tires without the "all-season" rating.\
However, for optimum road
holding on icy or snow-covered roads, we recommend suitable winter tires\
on all four wheels.
When replacing tires, be sure that the new tires are the same size desig\
nation, type (radial) and
preferably from the same manufacturer, on all four wheels. Otherwise the\
re is a risk of altering the
vehicle's roadholding and handling characteristics.
Storing wheels and tires
When storing complete wheels (tires mounted on rims), they should be s\
uspended off the floor or placed
on their sides on the floor.
Tires not mounted on rims should be stored on their sides or standing up\
right, but should not be
suspended. CAUTION!
Tires should preferably be stored in a cool, dry, dark place, and should\
never be stored in close
proximity to solvents, gasoline, oils, etc.
Tread wear indicator
The tires have wear indicator strips running across or parallel to the t\
read. The letters TWI are printed on
the side of the tire. When approximately 1/16" (1.6 mm) is left on the\
tread, these strips become visible
and indicate that the tire should be replaced. Tires with less than 1/16\
" (1.6 mm) tread offer very poor
traction.
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 alteration of the driving
characteristics of the vehicle.

Belt check
Check the belt regularly to make sure it is in good condition and is cle\
an. A worn or dirty belt can cause
poor cooling and low alternator output as well as impair the operation o\
f the power steering and the air
conditioning unit.
NOTE: The drive belt is equipped with a self-tensioning mechanism and require\
s no adjustment
between changes.
WARNING!
The engine must not be running when this check is
performed.
Check coolant level
The cooling system must be filled with coolant and not leak to operate a\
t maximum efficiency. Check
the coolant level regularly. The level should be between the "MAX" and "\
MIN" marks on the expansion
tank. The check should be made with particular thoroughness when the eng\
ine is new or when 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.
Changing coolant
Normally, the coolant does not need to be changed. If the system must be\
drained, consult your Volvo
retailer.
NOTE: Do not top off with water only. This reduces the rust-protective and an\
tifreeze qualities of the
coolant and has a lower boiling point. It can also cause damage to the c\
ooling system if it should freeze.
Top off with Volvo Genuine Coolant/Antifreeze only (a 50/ 50 mix of wat\
er and antifreeze). CAUTION!
The cooling system must always be kept filled to the correct level. If i\
t is not kept filled, there can be
high local temperatures in the engine which could result in damage. Diff\
erent types of antifreeze/
coolant may not be mixed.

CAUTION!
- Not checking the oil level regularly can result in serious engine dama\
ge if the oil level becomes too
low.
- Never fill oil above the MAX mark. This could cause an increase in oil\
consumption.
- Not checking the oil level regularly can result in serious engine dama\
ge if the oil level becomes too
low.
- Always add oil of the same type and viscosity as already used.
WARNING!
Do not allow oil to spill onto or come into contact with hot exhaust pip\
e
surfaces.
R-models
R-models are equipped with an oil level warning system. If the engine oi\
l level becomes too low, the
warning light in the instrument panel will come on and a warning will be\
displayed in the text window.
l If the yellow warning light in the instrument panel comes on and the tex\
t OIL LEVEL LOW/FILL
OIL is displayed, stop safely as soon as possible and add 1 qt (1 liter\
) of oil. Check the oil level with the
dipstick before restarting the engine.
l If the red warning light in the instrument panel comes on and the text O\
IL LEVEL LOW/STOP
SAFELY-->STOP ENGINE -->SEE MANUAL is displayed, stop safely as soon as \
possible and add oil
(not more than 1.6 qts (1.5 liters). Check the oil level with the dip\
stick before restarting the engine. If no
oil level is visible on the dipstick, do not start the engine. Have the \
vehicle towed to an authorized Volvo
retailer.
