2004 VOLVO XC70 Owners Manual

2004 VOLVO XC70
Towing cars with all wheel drive/front wheel drive
Volvo recommends the use of flat bed equipment. If wheel lift equipment \
must be used, please use
extreme caution to help avoid damage to the car. In this case, the car should be towed with the rear
wheels on the ground if at all possible.
If it is absolutely necessary to tow the vehicle with the front wheels o\
n the ground, please refer to the
towing information on the previous page.
CAUTION:
l The car must not be driven with wheels of different dimensions/specifica\
tions or with a spare tire
other than the one that came with the car. The use of different size whe\
els can seriously damage your
car's transmission.
l Sling-type equipment applied at the front will damage radiator and air c\
onditioning lines.
l It is equally important not to use sling-type equipment at the rear or a\
pply lifting equipment inside the
rear wheels; serious damage to the rear axle may result.
l If the car is being towed on a flat bed truck, the towing eyelets must n\
ot be used to secure the car on
the flat bed. Consult the tow truck operator.
WARNING!
l Do not use the towing eyelets to pull the car up onto a flat bed tow tru\
ck.

pg. 102 Towing a trailer
When preparing for trailer towing, observe the following:
Volvo recommends the use of Volvo trailer hitches which are specially de\
signed for the car.
l Maximum trailer weight recommended by Volvo is:
Trailers without brakes: 1100 lbs (500 kg)
Trailers with brakes: 3300 lbs* (1,500 kg),
Observe the legal requirements of the state/province in which the vehicl\
es are registered.
l All Volvo models are equipped with energy-absorbing shock-mounted bumper\
s. Trailer hitch
installation should not interfere with the proper operation of this bump\
er system.
Trailer towing does not normally present any particular problems, but ta\
ke into consideration:
l Increase tire pressure to recommended full. See section "Wheels and tire\
s".
l When your car is new, avoid towing heavy trailers during the first 620 m\
iles (1000 km).
l Recommended hitch tongue load is:
Trailer weights below 2,650 lbs (1,200 kg) - 110 lbs (50 kg)
Trailer weights above 2,650 lbs (1,200 kg) - 165 lbs (75 kg)
l Maximum speed when towing a trailer: 50 mph (80 km/h).
l Engine and transmission are subject to increased loads. Therefore, engin\
e coolant temperature should
be closely watched when driving in hot climates or hilly terrain. Use a \
lower gear and turn off the air
conditioner if the temperature gauge needle enters the red range.
l If the automatic transmission begins to overheat, a message will be disp\
layed in the text window.
l Avoid overload and other abusive operation.
l Hauling a trailer affects handling, durability, and economy.
l It is necessary to balance trailer brakes with the towing vehicle brakes\
to provide a safe stop (check
and observe state/local regulations).
l Do not connect the trailer's brake system directly to the vehicle's brak\
e system.
l More frequent vehicle maintenance is required.
l Remove the ball and drawbar assembly when the hitch is not being used.
l Volvo recommends the use of synthetic engine oil when towing a trailer o\
ver long distances or in
mountainous areas.

WARNING!
l Bumper-attached trailer hitches must not be used on Volvo's, nor should \
safety chains be attached
to the bumper.
l Trailer hitches attaching to the vehicle rear axle must not be used.
l Never connect a trailer's hydraulic brake system directly to the vehicle\
brake system, nor a trailer's
lighting system directly to the vehicle lighting system. Consult your ne\
arest authorized Volvo retailer
for correct installation.
l When towing a trailer, the trailer's safety wire must be correctly faste\
ned to the hole or hook
provided in the trailer hitch on the car. The safety wire should never b\
e fastened to or wound around
the drawbar ball.
NOTE:
l When parking the car with a trailer on a hill, apply the parking brake before putting the gear selector
in (P)ark. When starting on a hill, put the gear selector in (D)rive\
before releasing the parking brake.
l If you use the manual (Geartronic) shift positions while towing a trai\
ler, make sure the gear you select
does not put too much strain on the engine (using too high a gear).
l The drawbar assembly/trailer hitch may be certified for trailers that ar\
e heavier than the car is
designed to tow. Please adhere to Volvo's recommended trailer weights.
* When driving for prolonged periods at temperatures above 86° F (30\
° C), the maximum recommended
weight is 2000 lbs (900 kg).

l Then connect the auxiliary battery negative (-) terminal (3) to the \
ground point in your car's engine
compartment (4).
Start the engine in the assisting car, then start the engine in the car \
with the dead battery.
l After the engine has started, first remove the negative (-) terminal j\
umper cable. Then remove the
positive (+) terminal jumper cable.
CAUTION:
Improper hookup of jumper cables or use of other than 12-volt batteries \
could result in damage to
equipment and/or the battery.
WARNING!
l Do not connect the jumper cable to any part of the fuel system or to any\
moving parts. Avoid
touching hot manifolds.
l Never expose the battery to open flame or electric spark.
l Do not smoke near the battery.
l Batteries generate hydrogen gas which is flammable and explosive.
l Battery fluid contains sulfuric acid. Do not allow battery fluid to cont\
act eyes, skin, fabrics or
painted surfaces. If contact occurs, flush the affected area immediately\
with water. Obtain medical
help immediately if eyes are affected.
Failure to follow the instructions for jump starting can lead to persona\
l injury.
NOTE: Refer to
pages 140-141 for information on properly maintaining the battery.

Cold weather precautions
If you wish to check your car before the approach of cold weather, the f\
ollowing 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 car's radia\
tor. Your local Volvo
retailer stocks plenty of Volvo engine coolant to protect your car durin\
g 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 *, is recommended. Be sure to\
use good quality oil but do not
use this cold-weather oil for hard driving or in warm weather. See secti\
on "Engine 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 anti-rust oil on the batter\
y 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
page 136 for the location of the washer fluid reservoir). This is important sin\
ce dirt is often splashed on
the windshield during winter driving, requiring the frequent use of the \
washers and wipers. The Volvo
Washer Solvent should be diluted as follows:
Down to 14° F (-10° C): 1 part washer solvent and 4 parts water \
Down to 5° F (-15° C): 1 part washer solvent and 3 parts water
Down to 0° F (-18° C): 1 part washer solvent and 2 parts water
Down to -18° F (-28° C): 1 part washer solvent and 1 part water \
l Use Volvo Teflon Lock Spray in the locks.
NOTE: Avoid the use of de-icing sprays as they can cause damage to the locks.
W Winter/Wet driving mode - enhanced vehicle traction
l Mode W will only function if the gear selector is in the (D)rive posit\
ion.
l Press the button at the base of the gear selector to engage/disengage th\
is driving mode.
l An LED in the button will light up to indicate that W is engaged and this will also be displayed in the
instrument panel (see
page 27).
l This mode may be selected for starting/moving off on slippery roads.

*Synthetic oil is not used when the oil is changed at the normal mainten\
ance service intervals.

pg. 106 Long distance trips
Before a long distance trip
It is always worthwhile to have your car checked at a Volvo retailer bef\
ore driving long distances. Your
retailer will also be able to supply you with bulbs, fuses, spark plugs \
and wiper blades for your use in the
event that problems occur.
As a minimum, the following items should be checked before any long trip\
:
l Check that engine runs smoothly and that fuel consumption is normal.
l Check for fuel, oil, and fluid leakage.
l Check condition of accessory drive belts.
l Check transmission oil level*.
l Check state of the battery's charge.
l Examine tires carefully (the spare tire as well), and replace those th\
at are worn. Check tire pressures.
l The brakes, front wheel alignment, and steering gear should be checked b\
y your Volvo retailer only.
l Check all lights, including high beams.
l Reflective warning triangles are legal requirement in some countries.
l Have a word with your Volvo retailer if you intend to drive in countries\
where it may be difficult to
obtain the correct fuel.
l Consider your destination. If you will be driving through an area where \
snow or ice are likely to
occur, consider snow tires.
* To prevent injury from contact with hot surfaces, do not inspect your \
car's transmission fluid yourself.
Have your car's transmission fluid level inspected by a qualified Volvo \
service technician.

2004 VOLVO XC70
Three-way catalytic converter cautions
l Keep your engine properly tuned. Certain engine malfunctions, particular\
ly involving the electrical,
fuel or distributor ignition systems, may cause unusually high three-way\
catalytic converter
temperatures. Do not continue to operate your vehicle if you detect engine misfire, no\
ticeable loss of
power or other unusual operating conditions, such as engine overheating \
or backfiring. A properly
tuned engine will help avoid malfunctions that could damage the three-wa\
y catalytic converters.
l Do not park your car over combustible materials, such as grass or leaves\
, which can come into contact
with the hot exhaust system and cause such materials to ignite under cer\
tain wind and weather
conditions.
l Excessive starter cranking (in excess of one minute), with an intermit\
tently firing or flooded engine,
can cause three-way catalytic converter or exhaust system overheating.
l Remember that tampering or unauthorized modifications to the engine or t\
he vehicle may be illegal
and can cause three-way catalytic converter or exhaust system overheatin\
g. This includes:
- Altering fuel injection setting or components.
- Altering emission system components or location or removing components\
.
- Repeated use of leaded fuel.
NOTE: Unleaded fuel is required for cars with three-way catalytic converters \
