air conditioning VOLVO XC70 2003 Owners Manual

2003 VOLVO XC70
Volvo's environmental activities are based on a holistic view, which mea\
ns we consider the overall
environmental impact of a product throughout its complete life cycle. In\
this context, design, production,
product use, and recycling are all important considerations.
In production, Volvo has partly or completely phased out several chemica\
ls including freons, lead
chromates, naphtanates, asbestos, mercury and cadmium; and reduced the a\
mount of chemicals used in
our plants 50% since 1991.
In use, Volvo was the first in the world to introduce into production a \
three-way catalytic converter with
a Lambda sond, now called oxygen sensor, in 1976. The current version of\
this highly efficient system
reduces emissions of harmful substances (CO, HC, NOx) from the exhaust\
pipe by approximately 95%
and the search to eliminate the remaining emissions continues. Volvo is \
the only automobile
manufacturer to offer CFC-free retrofit kits for the air conditioning sy\
stem for all models as far back as
the M/Y 1975 240. Advanced electronic engine controls, refined purificat\
ion systems and cleaner fuels
are bringing us closer to our goal.
After Volvo cars and parts have fulfilled their use, recycling is the ne\
xt critical step in completing the
life cycle. The metal content is about 75% of the total weight of a car,\
which makes the car among the
most recycled industrial products. In order to have efficient and well c\
ontrolled recycling, many Volvo
variants have printed dismantling manuals, indicating the weight and mat\
erial of individual components.
For Volvo, all homogeneous plastic parts weighing more than 1.7 oz. (50\
grams) are marked with
international symbols that indicate how the component is to be sorted fo\
r recycling.
In addition to continuous environmental refinement of conventional gasol\
ine-powered internal
combustion engines, Volvo is actively looking at advanced technology alt\
ernative-fuel vehicles.
When you drive a Volvo, you become our partner in the work to lessen the\
car's impact on the
environment.
To reduce your vehicle's environmental impact, you can:
l Maintain proper air pressure in your tires. Tests have shown decreased f\
uel economy with improperly
inflated tires
l Follow the recommended maintenance schedule
l Drive at a constant speed
l See an authorized Volvo retailer as soon as possible for inspection if t\
he check engine (malfunction
indicator) lamp illuminates, or stays on after the vehicle has started \
l Properly dispose of any vehicle related waste such as used motor oil, us\
ed batteries, brake pads, etc.
l When cleaning your car, use Volvo's own car care products, all of which \
have systematically been
adapted to the environment

several minutes before driving will help release the warm air from the p\
assenger compartment. When
the engine is running, close the windows and sun roof and use the recirc\
ulation function for several
minutes to enable the air conditioning to cool the compartment as quickl\
y as possible.
Windows and optional sun roof
The ECC system will function best if the windows and optional sun roof a\
re closed. If you drive with the
sun roof open, we recommend that you manually adjust the temperature and\
blower control (the LED in
the AUTO switch should be off).
Acceleration
The air conditioning is momentarily disengaged during full-throttle acce\
leration.
ECC maintenance
All maintenance on the climate control systems should be carried out by \
an authorized Volvo service
technician only.
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. Th\
e system contains 2.2 lbs (1000
g) R134a and uses PAG oil.
Passenger compartment blower
Approximately 50 minutes after the ignition is turned off, the blower ma\
y come on automatically, and
run for five minutes, to remove condensation in the A/C evaporator.

AUTO
This function automatically regulates the Electronic Climate Control sys\
tem so that the selected
temperatures are maintained. The blower, heating, air distribution (air\
flow) and air conditioning are
controlled. If you prefer to manually set any of these functions, the re\
maining functions will still be
controlled automatically. Pressing the AUTO button overrides any setting\
s that were previously made
manually.
Temperature
These controls are used to individually set the temperature for both sid\
es of the passenger compartment.
Please note that the compartment will not be heated or cooled faster by \
setting the temperature higher or
lower than necessary. Set the control to the temperature you prefer.

y pressing OFF. When you
select Defroster
, the air conditioning is automatically engaged if the fan is not set to\
position 0.
Heated front seats (option)
Please see page 38 for more information on this function.
Heated rear window/sideview mirrors
This function demists/de-ices the rear window and sideview mirrors. The \
LED in the switch will light up
to indicate that the heating function is engaged. See
page 38 for additional information on this function.
CAUTION:
Never use ice scrapers made of metal as they can easily scratch the mirr\
or surface.
Recirculation
Recirculation can be used to shut out stale air, exhaust, etc. from the \
passenger compartment. The air in
the passenger compartment is then recirculated, i. e. no air from outsid\
e the car is taken into the car
when this function is activated. Recirculation (together with the air c\
onditioning system) cools the
passenger compartment more quickly in warm weather.
If you allow the air in the car to recirculate, there is a risk of icing\
and fogging, especially in winter. The
timer function minimizes the risk of ice, misting and stale air.
Activate the timer function as follows:

pattern, load-, speed-, traction-, temperature-, and treadwear rating. N\
ever drive on mixed tires, except
for brief periods when the temporary spare tire is in use.
Always use properly inflated tires of correct dimensions. Tire size and \
inflation pressures are shown on
the tire pressure label located inside the fuel filler door.
Tire Rotation
Volvo recommends rotating the tires every 7,500 miles (12,000 km). Tir\
es should be rotated front-to-
back/back-to-front only. Tires must maintain the same direction of rotat\
ion throughout their lifetime, and
should never be rotated from one side of the vehicle to the other.
Temporary Spare
The temporary spare tire is for temporary, low-speed, short-distance use\
only. Replace it with a full-
sized tire as soon as possible, in accordance with "Tire Rotation" above\
. Do not drive on the temporary
spare at speeds above 50 m.p.h. (80km/h) or for distances greater than\
50 miles (80 km).
Never install snow chains on a temporary spare.

pg. 95 Driving economy
Economical driving conserves natural resources
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 few minutes of operation. A cold eng\
ine 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 posted speed limits.
l Avoid carrying unnecessary items (extra load) in the car.
l Maintain correct tire pressure. Check tire pressure regularly (when tir\
es 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 also \
fuel consumption.
l Avoid using automatic transmission kickdown feature unless necessary.
l Avoid using the air conditioning when it is not required. When engaged, \
the conditioner's compressor
places an additional load on the engine. However, at higher driving spee\
ds, fuel consumption will be

lower with the air conditioning on and the windows closed than with the \
air conditioning off and the
windows open.
l Using the onboard trip computer's fuel consumption modes can help you le\
arn how to drive more
economically.
Other factors that decrease gas mileage are:
l Dirty air cleaner
l Dirty engine oil and clogged oil filter
l Dragging brakes
l Incorrect front end alignment Some of the above mentioned items and othe\
rs are checked at the
standard Maintenance Service intervals.
NOTE: Vehicles equipped with automatic transmissions should use (D)rive as o\
ften as possible and
avoid using "kick-down" to help improve fuel economy. Vehicles equipped \
with manual transmissions
should use fifth gear at highway speeds. At other times, choose the high\
est gear that still allows smooth
acceleration.
Weight distribution affects handling
At the specified curb weight your car has a tendency to understeer, whic\
h means that the steering wheel
has to be turned more than might seem appropriate for the curvature of a\
bend. This ensures good
stability and reduces the risk of rear wheel skid. Remember that these p\
roperties can alter with the
vehicle load. The heavier the load on the rear of the vehicle (e.g., he\
avily loaded (max. 220 lbs, 100 kg)
cargo area or when towing a trailer, the less the tendency to understeer\
.
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle hand\
ling. Therefore, check that the tires
are inflated to the recommended pressure according to the vehicle load. \
See "Tire pressure" section.
Loads should be distributed so that capacity weight or maximum permissib\
le axle loads are not
exceeded.

pg. 96 Points to remember
Cooling system
The risk for engine overheating is greatest, especially in hot weather, \
when:
l Towing a trailer up steep inclines for prolonged periods at wide open th\
rottle and low engine rpm.
l Stopping the engine suddenly after high speed driving (so-called "after\
-boiling" can occur).
l To avoid overheating, the following rules should be followed: Do not dri\
ve for prolonged periods at

2003 VOLVO XC70
engine speeds above 4500 rpm if you are towing a trailer in hilly terrai\
n.
Reduce speed when towing a trailer up long, steep inclines. The risk of \
overheating can be reduced by
switching off the air conditioning system for a short time.
Do not let the engine idle unnecessarily for prolonged periods.
Do not mount auxiliary lamps in front of the grill.
When the risk of overheating is imminent, or in the event of overheating\
(the temperature gauge goes
repeatedly into, or stays continually in, the red section), the followi\
ng precautions should be taken:
l Switch off the air conditioning system.
l Pull off the road, away from traffic, stop the car and put the gear sele\
ctor into neutral.
l Switch the heater to full (maximum) position. Increase the engine spee\
d to approx. 2000 rpm (twice
idling speed) until the temperature begins to drop.
WARNING!
Do not remove coolant expansion tank cap. The coolant will be extremely \
hot.
If necessary, see
page 129 and 132 for information on checking and topping-up the coolant
level.
CAUTION: Drive slowly and carefully if going through standing water (i.e. flood\
ed roadways, etc.).
Damage to the engine could result if excess water is drawn in through th\
e air intake system. Never drive
the vehicle in water deeper than 1 foot (300 mm). See the flood warnin\
g on
page 7.
WARNING!
l Driving with the tailgate open: Driving with the tailgate open could mean that poisonous exhaust
gases enter the passenger compartment.
If the tailgate must be kept open for any reason, proceed as follows:
- Close the windows.
- Set the ventilation system control to air flow to floor, windshield an\
d side windows and blower
control to its highest setting.
l Floor mats: An extra mat on the driver's floor can cause the accelerator pedal to \
catch. Check that
the movement of the accelerator pedal is not impeded. Not more than one \
protective floor covering
may be used at one time.
