Electrical system
When replacing the battery or when carrying out work involving the elect\
rical system, the following
should be observed:
l A battery connection to the wrong terminal will damage the electrical sy\
stem. Be sure to connect the
positive battery cable to the positive battery terminal and the negative\
battery cable to the negative
battery terminal.
l If booster batteries are used for starting, they must be properly connec\
ted to minimize the risk of the
electrical system being damaged. For correct connection, see "Jump start\
ing" section.
l Never disconnect the battery circuit (for example, to replace the batte\
ry) while the engine is running,
as this may damage the generator. Always make sure that all the battery \
connections are properly
cleaned and tightened.
l If any electrical welding work is performed on the vehicle, the battery'\
s ground lead (negative cable)
and all the connecting cables of the generator must be disconnected and \
the welder cables placed as near
the welding points as possible.
l The radio must be turned off before the battery is disconnected.
l Switch off the ignition for at least 10 minutes before disconnecting the\
battery.

pg. 97 Roof racks/Load carriers
Load carriers (accessory)
Load carriers are available as Volvo accessories. Observe the following \
points when in use:
l To avoid damaging your car and to achieve maximum safety when driving, w\
e recommend using the
load carriers that Volvo has developed especially for your car.
l Volvo-approved removable roof racks are designed to carry the maximum al\
lowable roof load for this
vehicle: 220 lbs (100 kg). For Non-Volvo roof racks, check the manufac\
turer's weight limits for the rack.
l Never exceed the rack manufacturer's weigh limits and never exceed the m\
aximum rated roof load of
220 lbs (100 kg).
l Avoid single-point loads. Distribute loads evenly.
l Place heavier cargo at the bottom of the load.
l Anchor the cargo correctly with appropriate tie-down equipment.
l Check periodically that the load carriers and load are properly secured.\

l Remember that the car's center of gravity and handling change when you c\
arry a load on the roof.
l The car's wind resistance (and correspondingly, fuel consumption) will\
increase with the size of the
load.
l Drive smoothly. Avoid rapid starts, fast cornering and hard braking.

l Maximum distance with front wheels on ground: 50 miles (80 km).
l While the car is being towed, try to keep the tow rope taut at all times\
.
l Cars with an automatic transmission should only be towed in forward dire\
ction.
CAUTION:
l Please check with state and local authorities before attempting this typ\
e of towing, as vehicles being
towed are subject to regulations regarding maximum towing speed, length \
and type of towing device,
lighting, etc.
l If the car's battery is dead, do not attempt to start the vehicle by pus\
hing or pulling it as this will
damage the three-way catalytic converter(s). The engine must be jump s\
tarted using an auxiliary battery
(see

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
truck.

Suitable detergents: Special car washing detergents should be used. Mix according to manufac\
turer's
instructions.
Bumpers: The bumpers are painted. Wash the bumpers with the same cleaning agent u\
sed on the rest of
the car. Never clean the bumpers with gasoline or paint thinner. Difficu\
lt spots can be removed with
denatured alcohol. To avoid scratches, do not dry the bumpers with paper\
. WARNING!
l When the car is driven immediately after being washed, apply the brakes \
several times in order to
remove any moisture from the brake linings.
l Engine cleaning agents should not be used when the engine is warm. This \
constitutes a fire risk.


pg. 128 Washing the car, Cleaning the upholstery
Automatic washing - simple and quick
l We do NOT recommend washing your car in an automatic wash during the fir\
st six months
(because the paint will not have hardened sufficiently).
l An automatic wash is a simple and quick way to clean your car, but it is\
worth remembering that it
may not be as thorough as when you yourself go over the car with sponge \
and water. Keeping the
underbody clean is most important, especially in the winter. Some automa\
tic washers do not have
facilities for washing the underbody.
l Before driving into an automatic wash, make sure that side view mirrors,\
auxiliary lamps, etc, are
secure, otherwise there is risk of the machine dislodging them.
Polishing and waxing
l Normally, polishing is not required during the first year after delivery\
. However, waxing may be
beneficial.
l Before applying polish or wax the car must be washed and dried. Tar spot\
s can be removed with
kerosene or tar remover. Difficult spots may require a fine rubbing comp\
ound.
l After polishing, use liquid or paste wax.
l Several commercially available products contain both polish and wax.
l Waxing alone does not substitute for polishing of a dull surface.
l A wide range of polymer-based car waxes can be purchased today. These wa\
xes are easy to use and
produce a long-lasting, high-gloss finish that protects the bodywork aga\
inst oxidation, road dirt and
fading.
