2015 Lancia Delta Owner handbook (in English)

WHEELS AND TYRES
Check the pressure of each tyre, including the space-saver
wheel, approximately every two weeks and before long
journeys: the pressure should be checked with the tyre rest-
ed and cold.
It is normal for the pressure to increase as the car is used;
see the “Wheels” paragraph in chapter “6” for the correct
tyre inflation pressure.
Incorrect pressure causes abnormal tyre wear fig. 2:
A normal pressure: tread evenly worn.
B low pressure: tread particularly worn at the edges.
C high pressure: tread particularly worn in the centre.
The tyres must be replaced when the tread is less than 1.6
mm thick. In any case, follow the laws in force in the coun-
try you are in.

IMPORTANT
❍Where possible, avoid braking suddenly, wheel-spin-
ning and crashing into curbs, potholes or other ob-
stacles. Driving for long stretches over bumpy roads
can damage the tyres;
❍ check the tyres regularly for cuts on the sides, swellings
or irregular tread wear. Go to a Lancia Dealership if
required.
❍ avoid overloading the car when travelling: this may
cause serious damage to the wheels and tyres;
❍ if a tyre is punctured, stop immediately and change it
to avoid damage to the tyre, wheel rim, suspension and
steering system;
❍ the tyre ages even if rarely used. Cracks in the tread and
on the side walls are a sign of ageing. Have the tyres
checked by specialised personnel if they have been fit-
ted for longer than 6 years. Remember to check the
space-saver wheel very carefully;
❍ when replacing the tyres, always fit new tyres, avoid-
ing those of dubious origin;

248MAINTENANCE AND CARE
❍if a tyre is replaced, you should also change the infla-
tion valve;
❍ to allow even wear between the front and rear tyres,
it is advisable to change them over every 10-15 thou-
sand kilometres, keeping them on the same side of the
car so as not to reverse the direction of rotation.
Remember that the road holding qualities of
your car also depend on the correct inflation
pressure of the tyres.
If the pressure is too low the tyre will get
overheated, with the risk of serious damage
to the tyre.
Avoid moving the tyres from the right side of
the vehicle to the left side and vice versa.
Do not repaint alloy wheel rims at temper-
atures higher than 150°C. The mechanical
specifications of the wheels might be ad-
versely affected.

RUBBER HOSES
As far as the brake system and fuel supply system rub-
ber hoses are concerned, follow the “Scheduled Servic-
ing Plan” in this chapter carefully.
Ozone, high temperatures and prolonged lack of fluid in
the system may cause hardening and cracking of the hoses,
with possible leaks. Careful checking is therefore neces-
sary.
WINDSCREEN/
REAR WINDOW WIPER
BLADES
Periodically clean the rubber part using special products;
TUTELA PROFESSIONAL SC35 is recommended.
Replace the blades if the rubber edge is deformed or worn.
In any case, it is advisable to replace them approximate-
ly once a year.
A few simple precautions can reduce the possibility of
damage to the blades:
❍make sure that the rubber part is not frozen to the
windscreen in case of sub-zero temperatures. Use a de-
icing product to release it if required;
❍ remove any snow from the glass: in addition to pro-
tecting the blades, this prevents effort from the motor
and overheating;
❍ do not operate the windscreen and the rear window
wipers on dry glass.
Driving with worn windscreen wiper blades
is a serious hazard, because visibility is re-
duced in bad weather conditions.

Changing the rear window wiper blade fig. 4
Proceed as follows:
❍ raise cover A and remove the arm from the car, slack-
ening nut B that fastens it to the pivot pin;
❍ fit the new arm, positioning it correctly, and fully tight-
en the nut;
❍ lower the cover.

NOZZLES
Windscreen washer fig. 5
If the jet of fluid is inadequate, firstly check that there is
fluid in the reservoir: (see “Checking levels” paragraph in
this chapter).
Then check that the nozzle holes are not clogged, if nec-
essary clean them using a needle.
The windscreen jets are directed by adjusting the nozzle
angle.
The jets should be directed at about a third of the height
from the top edge of the windscreen.
IMPORTANT In versions with a sun roof, make sure that
the sun roof is closed before operating the front jets.

The rear window washer jets are fixed. The nozzle hold-
er is located above the rear window.

252MAINTENANCE AND CARE
BODYWORK
PROTECTION AGAINST ATMOSPHERIC AGENTS
The main causes of corrosion are the following:
❍atmospheric pollution;
❍ salty air and humidity (coastal areas, or hot humid cli-
mates);
❍ seasonal environmental conditions.
The abrasive action of wind-borne atmospheric dust and
sand, as well as mud and gravel raised by other cars is
also not to be underestimated.
On your car, Lancia has implemented the best manufac-
turing technologies to effectively protect the bodywork
against corrosion. These include:
❍
paint products and systems which give the car a spe-
cial resistance to corrosion and abrasion;
❍ use of galvanised (or pre-treated) steel sheets with high
resistance to corrosion;
❍ spraying the underbody, engine compartment, wheel
arch internal parts and other elements with highly pro-
tective wax-based products;
❍ spraying protective plastic materials in the most ex-
posed areas: underdoor, inner wing parts, edges, etc.;
❍ using “open” boxed sections to prevent condensation
and pockets of moisture from causing rust inside.
BODY AND UNDERBODY WARRANTY
Your car is covered by warranty against perforation due
to rust of any original element of the structure or body-
work.
For the general terms of this warranty, refer to the War-
ranty Booklet.
233-256 Delta GB 1ed 03/04/14 13:28 Pagina 252

❍wash the bodywork using a low pressure jet of water;
❍ wipe a sponge with a slightly soapy solution over the
bodywork, frequently rinsing the sponge;
❍ rinse well with water and dry with a jet of air or a
chamois leather.
Dry the less visible parts with special care, such as the door
frames, bonnet and the headlight frames, where water may
stagnate more easily. The car should not be taken to a
closed area immediately, but left outside so that residual
water can evaporate.
Do not wash the car after it has been left in the sun or with
the bonnet hot: this may alter the shine of the paintwork.
Exterior plastic parts must be cleaned in the same way
as the rest of the car.
Where possible, do not park under trees; the resinous sub-
stance that many species release give the paint a dull ap-
pearance and increase the possibility of triggering rust-
ing processes.
ADVICE FOR PRESERVING THE BODYWORK
Paintwork
Paintwork does not only serve an aesthetic purpose, but
also protects the underlying sheet metal.
Touch up abrasions and scratches immediately to prevent
rust formation. Use only original paint products for touch-
ups (see “Bodywork paint identification plate” in the
“Technical specifications” chapter).
Normal maintenance of paintwork consists in washing the
car: the frequency depends on the conditions and envi-
ronment where the car is used. For example, in highly pol-
luted areas, or if the roads are spread with salt, it is ad-
visable to wash the car more frequently.
To correctly wash the car, proceed as follows:
❍
if taking your car through an automatic car wash, re-
move the aerial from the roof to avoid damaging it;
❍ in washing stations keep the steam jets/high pressure
washing nozzles at least 40 cm away from the body-
work to prevent damage. It should be remembered that
the build up of water can damage the car over a peri-
od of time;

254MAINTENANCE AND CARE
In order to preserve the aesthetic appear-
ance of the paintwork abrasive products
and/or polishes should not be used for clean-
ing the car.
Detergents pollute the environment. Only
wash the car in areas equipped for the col-
lection and purification of the fluids used in
the washing process.
Hard Black versions
Avoid washing with rollers and/or brushes
in washing stations. Then, wash the car, on-
ly by hand, using pH-neutral detergents; dry
it with a wet chamois leather. Abrasive products
and/or polishes should not be used for cleaning the
car. Bird droppings must be washed off immediately
and thoroughly as the acid they contain is partic-
ularly aggressive. Avoid (if at all possible) park-
ing the car under trees; remove vegetable resins im-
mediately as, when dried, it may only be possible
to remove them with abrasive products and/or pol-
ishes, which is highly inadvisable as they could al-
ter the typical opacity of the paint. Do not use pure
windscreen washer fluid for cleaning the front
windscreen and rear window; dilute it min. 50%
with water.
IMPORTANT Bird droppings must be washed off imme-
diately and thoroughly, as the acid they contain is par-
ticularly aggressive.
