Cleaning the exterior
The car should be washed as soon as it
becomes dirty. This means that the car is easier
to clean since the dirt does not attach as firmly.
It also reduces the risk of scratches and keeps
the car fresh. Wash the car in a car wash with oil
separator. Use car shampoo.
Handwashing
The following steps are good to remember when
washing the car:
•
Avoid washing the car in direct sunlight. This
can cause the detergent or wax to dry and
have an abrasive effect.
•
Remove bird droppings from the paintwork
as soon as possible. Bird droppings contain
chemicals that affect and discolour paintwork
very quickly. For example, use soft paper or
sponge soaked in plenty of water. An author-
ised Volvo workshop is recommended for the
removal of any discoloration.
•
Wash the underbody, including wheel hous-
ings and bumpers.
•
Rinse the entire car until the dissolved dirt
has been removed so as to reduce the risk of
scratches from washing. Do not spray directly
onto the locks.
•
If necessary, use cold degreasing agent on
very dirty surfaces. Note that in this case, the
surfaces must not be hot from the sun.
•
Wash using a sponge, car shampoo and
plenty of lukewarm water.
•
Clean the wiper blades with a lukewarm soap
solution or car shampoo.
•
Dry the car using a clean, soft chamois or a
water scraper. If you avoid allowing drops of
water to dry in strong sunlight, you reduce
the risk of water drying stains which may
need to be polished out.
•
After the car has been washed, tar from
asphalt may remain. Use tar remover to get
rid of the last spots after the car has been
washed.
WARNING
Always have the engine cleaned by a work-
shop. There is a risk of fire if the engine is hot.
Dirty headlamps have impaired functionality.
Clean them regularly, e.g. when refuelling.
Do not use any corrosive cleaning agents but
use water and a non-scratching sponge
instead.
Outside lighting such as headlamps and rear
lamps may temporarily have condensation on
the inside of the lens. This is normal, all exte-
rior lighting is designed to withstand this.
Condensation is normally vented out of the
lamp housing when the lamp has been
switched on for a time.
•
Make sure that the panoramic roof and
sun visor are closed before washing the
car.
•
Never use polishing agent with abrasive
properties on the panoramic roof.
•
Never use wax on the rubber mouldings
around the panoramic roof.
Remember to remove dirt from the drain
holes in the doors and in the sills after wash-
ing the car.
Automatic car wash
An automatic car wash is a simple and quick way
of washing the car, but it cannot reach every-
where. Washing the car by hand is recommended
||
MAINTENANCE AND SERVICE

to achieve a good result, or to supplement auto-
matic car washes with washing by hand.
The car must only be washed by hand over
the first few months. This is because the paint
is more delicate when it is new.
Before driving the car into an automatic car
wash, deactivate the functions for automatic
braking when stationary and automatic park-
ing brake application. If these functions are
not deactivated, the brake system will jam
when the car is stationary and the car will not
be able to move.
In car washes where the car is towed through
with rolling wheels, the following applies:
1. Drive into the automatic car wash.
2. Deactivate the function for Automatic brak-
ing when stationary using the switch in the
tunnel console.
3. Deactivate the function for automatic appli-
cation of parking brake via the centre dis-
play's top view.
4. Move the gear lever to position N.
5. Switch off the engine by turning the start
knob in the tunnel console clockwise. Hold
the knob in place at least 4 seconds.
> The car is ready for the automatic car
wash.
The system will automatically switch to P
mode unless the above step is followed. The
wheels are locked in P mode, which they
should not be when putting the car through
an automatic car wash.
•
Before washing the car, make sure that
the automatic rain sensor is deactivated,
otherwise there is the risk of it starting
and damaging the wiper arms.
•
Make sure that the door mirrors are
retracted, any auxiliary lamps secured,
antennas retracted or removed, otherwise
they risk being damaged by the auto-
matic car wash.
High-pressure washing
When using high-pressure washing, use sweep-
ing movements and make sure that the nozzle
does not come closer than 30 cm to the surface
of the car. Do not spray directly onto the locks.
Testing the brakes
Lightly depress the brake pedal now and then
when driving long distances in rain or slush. The
heat from the friction causes the brake linings to
warm up and dry. Do the same thing after starting
in very damp or cold weather.
WARNING
Always test the brakes after washing the car,
including the parking brake, to ensure that
moisture and corrosion do not attack the
brake linings and reduce braking perform-
ance.
Wiper blades
Asphalt, dust and salt residue on wiper blades, as
well as insects, ice etc. on the windscreen, impair
the service life of wiper blades.
When cleaning, set the wiper blades in service
position.
Wash the wiper blades and windscreen regu-
larly with a lukewarm soap solution or car
shampoo. Do not use any strong solvents.
Exterior plastic, rubber and trim
components
A special cleaning agent available from Volvo
dealers is recommended for the cleaning and

care of coloured plastic parts, rubber and trim
components, e.g. glossy trim mouldings. When
using such a cleaning agent the instructions
must be followed carefully.
Avoid washing the car with detergent with a pH
value below 3.5 or above 11.5. This can cause
discolouration of anodised aluminium compo-
nents
*, as illustrated. We advise against use of
abrasive polishing agents, as illustrated.
Parts that should be washed using a cleaning agent with
a pH value between 3.5 and 11.5.
Avoid waxing and polishing on plastic and
rubber.
When using degreasant on plastic and rubber,
only rub with light pressure if it is necessary.
Use a soft washing sponge.
Polishing glossy trim mouldings could wear
away or damage the glossy surface layer.
Polishing agent that contains abrasive must
not be used.
Avoid washing the car with cleaning agent
with a pH value lower than 3.5 or higher than
11.5. This may result in discolouration of ano-
dised aluminium parts such as roof rack and
around the side windows.
Never use metal polishing agent on anodised
aluminium parts, this can result in discoloura-
tion and destroy the surface treatment.
Rims
Only use rim cleaning agent recommended by
Volvo.
Strong rim cleaning agents can damage the sur-
face and cause stains on chrome-plated alumi-
nium rims.

Polishing and waxing
Polish and wax the car if the paintwork is dull or
to give the paintwork extra protection. The car
does not need to be polished until it is at least
one year old. However, the car can be waxed
during this time. Do not polish or wax the car in
direct sunlight, the surface being polished
should be a maximum of 45 °C (113 °F).
•
Wash and dry the car thoroughly before you
begin polishing or waxing. Clean off asphalt
and tar stains using tar remover or white spi-
rit. More stubborn stains can be removed
using fine rubbing paste designed for car
paintwork.
•
Polish first with a polish and then wax with
liquid or solid wax. Follow the instructions on
the packaging carefully. Many preparations
contain both polish and wax.
Avoid waxing and polishing on plastic and
rubber.
When using degreasant on plastic and rubber,
only rub with light pressure if it is necessary.
Use a soft washing sponge.
Polishing glossy trim mouldings could wear
away or damage the glossy surface layer.
Polishing agent that contains abrasive must
not be used.
Only paint treatment recommended by Volvo
should be used. Other treatment such as pre-
serving, sealing, protection, lustre sealing or
similar could damage the paintwork. Paint-
work damage caused by such treatments is
not covered by Volvo warranty.

Rustproofing
The car has effective protection against corro-
sion.
Anti-corrosion protection for the body consists of
modern metallic protective coatings on the sheet
metal, a high-quality painting process, corrosion-
protected and minimised metal overlap, and
shielding plastic components, abrasion protection
and supplemental rust inhibitor in exposed areas.
This combination guarantees that the body will
remain free from corrosion problems over time. In
the chassis, exposed components of the wheel
suspension are made of corrosion-resistant cast
aluminium.
Inspection and maintenance
The car's anti-corrosion protection normally
requires no maintenance, but a good way to fur-
ther reduce the risk of corrosion is to keep the
car clean. Strong alkaline or acidic cleaning solu-
tions must always be avoided on glossy trim com-
ponents. Any stone chips should be rectified as
soon as they are discovered.

Cleaning the interior
Only use cleaning agents and car care products
recommended by Volvo. Clean regularly and
treat stains at once for best results. Vacuuming
is important prior to using cleaning agents.
•
Certain items of coloured clothing (e.g.
dark jeans and suede garments) may
stain the upholstery. If this occurs, it is
important to clean and treat these parts
of the upholstery as soon as possible.
•
Never use strong solvents such as
washer fluid, pure petrol or white spirit to
clean the interior, since this may damage
the upholstery as well as other interior
materials.
•
Never spray the cleaning agent directly
onto components that have electrical but-
tons and controls. Wipe them instead
using a moistened cloth containing the
cleaning agent.
•
Sharp objects and Velcro may damage
the fabric upholstery.
Fabric upholstery and ceiling upholstery
Never scrape or rub a stain since this risks
destroying the upholstery. Never use strong stain
removers since this risks destroying the colour of
the upholstery.
Leather upholstery
*
Volvo's leather upholstery is treated to preserve
its original appearance.
Leather upholstery is a natural product that
changes and acquires a beautiful patina over
time. Regular cleaning and treatment are
required in order that the properties and colours
of the leather shall be preserved. Volvo offers a
comprehensive product – Volvo Leather Care Kit/
Wipes – for the cleaning and treatment of leather
upholstery which, when used in accordance with
the instructions, preserves the leather's protective
coating.
To achieve best results, Volvo recommends
cleaning and application of the protective cream
one to four times per year (or more if required).
Volvo Leather Care Kit/Wipes is available from
Volvo dealers.
Cleaning the leather upholstery
1. Apply the leather cleaner to a damp sponge
and squeeze until a foam is created.
2. Use the sponge on the stain in a circular
motion.
3. Thoroughly dampen the stain using the
sponge, allow the sponge to absorb the stain
without scrubbing.
4. Wipe the stain with a soft cloth and allow the
leather to dry thoroughly
Protecting the leather upholstery
1. Apply a small amount of leather protective
agent to a cloth and then apply it to the
leather in light circular motions.
2. Allow to dry for about 20 minutes.
Protecting the leather upholstery makes it more
resistant to the stresses from the sun's UV radia-
tion.
Leather steering wheel
Leather needs to breathe. Never cover the
leather steering wheel with protective plastic. We
recommend Volvo Leather Care Kit/Wipes for
cleaning the leather steering wheel. First remove
dirt, dust, etc. with a damp sponge or cloth and a
neutral soapy solution.
Sharp objects, e.g. rings, can damage the
leather on the steering wheel.
Interior plastic, metal and wood parts
A fibrillated fibre or microfibre cloth, lightly mois-
tened with water, available from Volvo dealers, is
recommended for cleaning interior parts and sur-
faces.
Do not scrape or rub stains. Never use strong
stain removers.
