cooling VOLVO XC70 2003 Owners Manual

2003 VOLVO XC70
Driving in rain and slush or passing through an automatic car wash can c\
ause water to collect on the
brake discs and pads. This will cause a delay in braking effect when the\
pedal is depressed. To avoid
such a delay when the brakes are needed, depress the pedal occasionally \
when driving through rain,
slush etc. This will remove the water from the brakes. Check that brake \
application feels normal. This
should also be done after washing or starting in very damp or cold weath\
er.
Severe strain on the brake system
The brakes will be subject to severe strain when driving in mountains or\
hilly areas or towing. Vehicle
speed is usually slower, which means that the cooling of the brakes is l\
ess efficient than when driving on
level roads. To reduce the strain on the brakes, shift into a lower gear\
and let the engine help with the
braking. Do not forget that, if you are towing a trailer, the brakes wil\
l be subjected to a greater than
normal load.
pg. 19 Anti-lock Brake System (ABS)


Anti-lock Brake System (ABS)
If the warning lamp lights up there is a malfunction of the ABS system (\
the standard braking system will
however function) and the vehicle should be driven cautiously to a Volv\
o retailer for inspection. The
Anti-lock Braking System (ABS) helps to improve vehicle control (stop\
ping and steering) during severe
braking conditions by limiting brake lockup. When the system "senses" im\
pending lockup, braking
pressure is automatically modulated in order to help prevent lockup, whi\
ch could lead to a skid.
The system performs a self-diagnostic test when the engine is started an\
d when the vehicle first
reaches a speed of approximately 12 mph (20 km/h). The brake pedal will pulsate several times and a
sound may be audible from the ABS control module. This is normal.
To obtain optimal effect from the ABS system, constant pressure should b\
e kept on the brake
pedal, keep constant pressure on the brake pedal. Do not pump the brake \
pedal.
The switching of the ABS modulator will be audible and the brake pedal w\
ill pulsate during braking.
Please be aware that ABS does not increase the absolute braking potentia\
l of the vehicle. While control
will be enhanced, ABS will not shorten stopping distances on slippery su\
rfaces.
ABS with EBD (Electronic Brake Force Distribution)
EBD is an integrated part of the ABS system. EBD regulates the hydraulic\
pressure to the rear brakes to
help provide optimal braking capacity. The brake pedal will pulsate duri\
ng braking, which is normal.

Condensation on the inside of the windows
Keeping the insides of the windows clean will help reduce the amount of \
condensation that forms on the
windows. Use a commercial window cleaning agent to clean the windows.
Ice and snow
Always keep the air intake grille at the base of the windshield free of \
snow.
Cabin air filter
Replace the cabin air filter with a new one at the recommended intervals\
. The filter should be replaced
more often when driving under dirty and dusty conditions. The filter can\
not be cleaned and therefore
should always be replaced with a new one.
Sensors
The sunlight sensor on the dashboard and passenger compartment temperatu\
re sensor in the ECC control
panel should not be covered in any way as this could cause incorrect inf\
ormation to be sent to the ECC
system.

With the exception of gas line antifreeze during winter months, do not a\
dd solvents, thickeners, or other
store-bought additives to your car's fuel, cooling, or lubricating syste\
ms. Overuse may damage your
engine, and some of these additives contain organically volatile chemica\
ls. Do not needlessly expose
yourself to these chemicals.

pg. 86 Refueling

Refueling
The fuel tank holds approximately 18.5 US gals (70 liters) or 19 US ga\
ls (72 liters) on models equipped
with All Wheel Drive, with sufficient volume left over to accommodate po\
ssible expansion of the fuel in
hot weather. Be aware that the "usable" tank capacity will be somewhat l\
ess than the specified
maximum. When the fuel level is low, such factors as ambient temperature\
, the fuel's "Reid vapor
pressure" characteristics, and terrain can affect the fuel pump's abilit\
y to supply the engine with an
adequate supply of fuel. Therefore, it is advisable to refuel as soon as\
possible when the needle nears the
red zone, or when the fuel warning light comes on.
Fuel filler door
Press the button on the light switch panel (see illustration on page 34) when the car is at a standstill to
unlock the fuel filler door. Please note that the fuel filler door will \
remain unlocked until the car begins
to move forward. An audible click will be heard when the fuel filler doo\
r relocks.
If you intend to leave your car while it is being refueled, this feature\
s enables you to lock the door/
tailgate while leaving the fuel filler door unlocked.
You can also keep the car locked if you remain inside it during refuelin\
g. The central locking button
does not lock the fuel filler door.
Be sure the fuel filler door is not obstructed and is completely closed \
after refueling. Open the fuel
filler cap slowly during hot weather conditions.

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

four wheels. When replacing tires, be sure that the new tires are the same dimensio\
ns, type (radial) and
preferably from the same manufacturer, on all four wheels. Do not use bi\
as ply tires. Otherwise there is a
risk of altering the car's roadholding and handling characteristics.
NOTE: When storing wheel/tire assemblies (e.g. snow tires and wheels), eith\
er stand the assemblies
upright, or suspend them off the ground. Laying wheel/tire assemblies on\
their sides for prolonged
periods can cause wheel and/or tire damage.
Wear indicator
The tires have wear indicator strips running across or parallel to the t\
read. When approx. 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 have very poor grip in rain \
or snow.
To improve tire economy:
l Maintain correct tire pressure. See the tire pressure label on the insid\
e of the fuel filler door.
l Drive smoothly: avoid fast starts, hard braking and tire screeching.
l Tire wear increases with speed.
l Correct front wheel alignment is very important.
l Unbalanced wheels impair tire economy and driving comfort.
l Volvo does not recommend rotating the tires. However, if tires are rotat\
ed, they must be kept on the
same side of the car so that they revolve in the same direction as befor\
e rotation.
l Hitting curbs or potholes can damage the tires and/or wheels permanently\
.
Flat spots
All tires become warm during use. After cooling, when the vehicle is par\
ked, the tires have a tendency to
distort slightly, forming flat spots. These flat spots can cause vibrati\
ons similar to the vibrations caused
by unbalanced wheels. They do, however, disappear when the tire warms up\
. The degree to which flat
spots form depends on the type of cord used in the tire. Remember that, \
in cold weather, it takes longer
for the tire to warm up and consequently longer for the flat spot to dis\
appear.
CAUTION: The car must not be driven with wheels of different dimensions/specific\
ations or with a
spare tire other than the one that came with the car. The use of differe\
nt size wheels can seriously
damage your car's transmission or driveline.

charcoal canister to the engine's air intake system and into the combust\
ion process.
NOTE:
l Overfilling the fuel tank can cause damage to the evaporative control sy\
stem.
l If the fuel filler cap is not closed tightly or if the engine is running\
when the car is refueled, the
Malfunction Indicator Lamp may indicate a fault.
l During a transitional period, a small number of service stations may sti\
ll have fuel nozzles that are not
compatible with the fuel filler neck on cars equipped with the evaporati\
ve emission control system
mandated by the U.S. Environmental Protection Agency and the California \
Air Resources Board. If you
experience difficulties in refueling your vehicle, please ask the gas st\
ation attendant for assistance.
CAUTION:
Fuel must not be siphoned from the fuel tank. This will damage the evapo\
rative control system.

pg. 131 Drive belt, Coolant
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 requires\
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.
Frequent removal may prevent coolant circulation between the engine and \
the expansion tank during

engine 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 ant\
ifreeze 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.
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.
WARNING!
Never remove the radiator cap while the engine is warm. Wait until the c\
ar
cools.


pg. 132 Emissions maintenance
Periodic maintenance helps minimize emissions
Periodic maintenance will help keep your vehicle running well. Your Warr\
anty and Service Records
Information booklet provides a comprehensive periodic maintenance schedu\
le up to 150,000 miles
(240,000 km) of vehicle service. The schedule includes components that\
affect vehicle emissions. This
page describes some of the emission-related components.
Engine air filter
The engine air filter cleans particles from air entering the engine. Rep\
lace the engine air filter cartridge
with a new one every 37,500 miles (60,000 km) under normal driving con\
ditions. Replace the cartridge
