Heating and air conditioning

Volvo cares about the environment. Your Volvo is equipped with a heating\
system combined with air
conditioning. Depending on which function you select, warm or cool/cold \
air is distributed to the
different parts of the passenger compartment. A slight amount of condens\
ation may be emitted from the
air vents when the air conditioning is initially switched on. This can o\
ccur when both humidity and
ambient temperature are high and is normal.

Refrigerant

Volvo cares about the environment. The air conditioning system in your c\
ar contains a CFC-free
refrigerant -R134a. This substance will not deplete the ozone layer. The\
system contains 1.65 lbs (0.75
kg) R134a and uses ZXL 100PG (type PAG) oil.

Air vents (dash)

A Closed
B Open
C Directing air flow horizontally
D Directing air flow vertically

Air mix

The center panel vents have an air mix function which allows fresh air t\
o enter the passenger
compartment when the vents are open (position B). This function is des\
igned to allow you to direct cool
air toward you face while directing warmer air to the rest of the passen\
ger compartment.
To warm the compartment as quickly as possible, the air mix control shou\
ld be in the closed position. pg. 1:20 Heating, ventilation and air conditioning (standard unit)

Additional information

l The air conditioning system will function best if it is used regularly (\
at least once a month).
l Water under the vehicle in hot weather can be the result of condensation\
from the air conditioning
system and is quite normal.
l The air conditioning system functions only at temperatures above 32° \
F (0° C).
l Choose this position if the outside air is contaminated with exhaust ga\
ses, smoke, etc or to heat/
cool the car quickly. In this position, very little air is drawn into th\
e passenger from the outside. Do not
leave the system in this mode for more than 10-15 minutes since the air \
inside the car will become stale.
The temperature can be controlled with the temperature selectors.
l If the panel vents are open, a certain amount of air will always flow th\
rough, regardless of the position
the function selector is in. To increase the flow of air to either the f\
loor or the windows, close the panel
vents. The outer vents can be opened to avoid mist on the side windows. \
l The panel vents may emit some condensation when the air conditioning is \
initially switched on and is
quite normal. This may occur if the ambient temperature and humidity are\
high.
l The air conditioning is momentarily disengaged during full-throttle acce\
leration.

Set the mode selector to AUT and select the desired temperature. If the \
driver's side temperature selector
is set to either the max heating or max cooling position, the blower wil\
l run at its maximum speed.

Optimum defrosting


Set the function selector to
. and move the blower control to the position AUT (as far to the left \
as
possible). The A/C system will be on at this time regardless of the A/C\
button's position and the blower
will run at its maximum speed. When the windows have cleared, set the fu\
nction selector in the AUT
position.

l The air conditioning system will function best if it is used regularly (\
at least once a month).
l Always keep the air intake grille at the base of the windshield free of \
snow.

compartment from outside. Do not leave the system in this mode for more \
than 10-15 minutes, since the
air inside the car will become stale and condensation will form on the w\
indows.

NOTE: To help maintain stable passenger compartment temperature when dri\
ving with the sun roof or
windows open, place the blower control in position "0" and adjust the de\
sired temperature manually.

l If the panel vents are open, a certain amount of air will always flow th\
rough, regardless of the position
the function dial is in. To increase the flow of air to either the floor\
or the windows, close the panel
vents. The outer vents can be opened to avoid mist on the side windows. \
l The panel vents may emit some condensation when the air conditioning is \
initially switched on and is
quite normal. This may occur if the ambient temperature and humidity are\
high.
l The sunlight sensor (located at the top center of the dashboard) shoul\
d not be covered in any way as
this could cause incorrect information to be sent to the ECC system.
l The air conditioning is momentarily disengaged during full-throttle acce\
leration.

Difficult weather conditions

When driving in very humid conditions, heavy rain, sleet, etc., it may b\
e better to use the manual rather
than the automatic setting to defrost the windows. Set the mode selector\
to "Defrost"
or "Defrost/
floor" and the fan speed to 3 or higher. Also shut the middle air vents.\


Faults in the ECC system

The REC and AC OFF lights will flash for approximately 20 seconds if a f\
ault is detected in the ECC
system.
If this flashing recurs the next time the system is switched on, the cli\
mate control unit should be checked
by an authorized Volvo retailer.

CAUTION: Take care not to spill gasoline during refueling. Gasolines con\
taining alcohol can cause
damage to painted surfaces, which may not be covered under the New Vehic\
le Limited Warranty.
Do not use gasoline containing methanol (methyl alcohol, wood alcohol)\
. This practice can result in
vehicle performance deterioration and can damage critical parts in the f\
uel system. Such damage may
not be covered under the New Vehicle Limited Warranty.
pg. 4:4 Driving economy
Economical driving does not necessarily mean driving slowly

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. Obs\
erve the following rules:
l Bring the engine to normal operating temperature as soon as possible by \
driving with a light foot on
the accelerator pedal for the first minutes of operation. A cold engine \
uses more fuel and is subject to
increased wear.
l Whenever possible, avoid using the car for driving short distances. This\
does not allow the engine to
reach normal operating temperature.
l Drive carefully and avoid rapid acceleration and hard braking.
l Do not exceed speed limit.
l Avoid carrying unnecessary items (extra load) in the car.
l Check tire pressure regularly (check when tires are cold).
l Remove snow tires when threat of snow or ice has ended.
l Note that roof racks, ski racks, etc., increase air resistance and there\
by fuel consumption.
l Avoid using automatic transmission kick-down feature unless necessary.
l Avoid using the air conditioning when it is not required. When engaged, \
the air conditioner's
compressor places places an additional load on the engine.
l If your car is equipped with the optional Trip Computer, utilizing the f\
uel consumption modes can
help you "learn" how to drive more economically.

Other factors which decrease gas mileage are:
l Low tire pressure
l Worn or dirty spark plugs
l Incorrect spark plug gap
l Dirty air cleaner
l Dirty engine oil and clogged oil filter
l Dragging brakes
l Incorrect front end alignment
