trailer VOLVO XC70 2004 Owners Manual

2004 VOLVO XC70
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the \
engine is running. Never let
the vehicle roll to a stop with the engine switched off.
If the power brakes are not working, the brake pedal must be pressed app\
roximately four times harder
than usual to make up for the lack of power assistance. This can happen \
for example when towing your
vehicle or if the engine is switched off when the vehicle is rolling. Th\
e brake pedal feels harder than
usual.
Water on brake discs and brake pads affects braking
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.

Oil pressure warning light
If the light comes on while driving, stop the car and then stop the engi\
ne immediately and check the
engine oil level. See
page 138. If the light stays on after restart, have the car towed to the nearest\
authorized
Volvo retailer. After hard driving, the light may come on occasionally w\
hen the engine is idling. This is
normal, provided it goes off when the engine speed is increased.

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).

recommends use of oil with a quality rating equal to or higher than ILSA\
C GF-2. Equivalent and better
oils include ACEA A1, API SJ, SJ/CF, and SJ/Energy conserving. Lower qua\
lity oils may not offer the
same fuel economy, engine performance, or engine protection.
Volvo Cars recommends Castrol.
Depending on your driving habits, premium or synthetic oils may provide \
superior fuel economy and
engine protection. Consult your Volvo retailer for recommendations on pr\
emium or synthetic oils.
Oil additives must not be used.
NOTE: Synthetic oil is not used when the oil is changed at the normal mainten\
ance services. This oil is
only used at customer request, at additional charge. Please consult your\
Volvo retailer.
Oil viscosity (stable ambient temperatures)
Oil viscosity (stable ambient temperatures)
Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when t\
emperatures do not exceed 86 °F
(30°C), SAE 5W/30 will provide good fuel economy and engine protect\
ion. See the viscosity chart
below.
Operation in hot climates
When temperatures exceed 86 °F (30°C) in your area, Volvo recomm\
ends, for the protection of your
engine, that you use a heavier weight oil, such as SAE 10W/30. See the v\
iscosity chart below.
Extreme engine operation
Synthetic oils meeting SAE 10W/30 and complying with oil quality require\
ments are recommended for
driving in areas of sustained temperature extremes (hot or cold), when\
towing a trailer over long
distances, and for prolonged driving in mountainous areas.
Changing oil and oil filter
Oil and oil filter changes should be made at 7,500 mile (12,000 km) in\
tervals.
