warning light SKODA CITIGO 2017 Service Manual

The tyre pressure monitoring function (hereinafter referred to as: the system)
monitors the tyre pressure while driving.
If the tyre inflation pressure changes, the warning light 
lights up in the in-
strument cluster and an audible signal is heard » page 34, 
.
The system can only function properly if the tyres have the prescribed inflation pressure and these pressure values are stored in the system.WARNING■ The general information relating to the use of assistance systems must
be observed » page 103, in section Introduction .■
Having the correct tyre inflation pressure is always the driver's responsi-
bility. Tyre pressure should be checked regularly » page 129.
■
The system cannot warn in case of very rapid tyre inflation pressure loss,
e.g. in case of sudden tyre damage.

WARNING■Vehicle care products may be harmful to your health if not used according
to the instructions.■
Always keep the vehicle care products safe from people who are not com-
pletely independent, e.g. children - danger of poisoning!
CAUTION
■ Do not use any insect sponges, rough kitchen sponges or similar cleaning
products – risk of damaging the paintwork surface.■
Do not use aggressive cleaning agents or chemical solvents - danger of dam-
aging the surface to be cleaned.
Note
We recommend that the vehicle is cleaned and maintained at a ŠKODA service
partner.
Car washing
Read and observe
and on page 114 first.
The best way to protect your vehicle against harmful environmental influencesis frequent washing.
The longer insect residues, bird droppings, road salt and other aggressive de-
posits remain on the paintwork of your vehicle, the more detrimental their de-
structive effect can be. High temperatures, such as those caused by intensive
sun's rays, accentuate this caustic effect.
It is also essential to thoroughly clean the underside of the vehicle at the end
of the winter.
Washing by hand
Wash the vehicle from top to bottom, with a soft sponge or a wash mitt and
plenty of water, and, if necessary, with the appropriate detergents. Wash out
the sponge or washing glove thoroughly at short intervals.
For wheels, door sills and lower areas of the vehicle use a different sponge.
Give the vehicle a good rinse after washing it and dry it off using a chamois
leather.
Automatic Car Washes
The usual precautionary measures must be taken before washing the vehicle
(e.g. closing the windows and the tilt/slide roof etc.).
If your vehicle is fitted with any particular attached parts (e.g. spoiler, roof rack
system, two-way radio aerial etc.) it is best to consult the operator of the car
wash system beforehand.
After an automatic wash with wax treatment, the wiper blades should be
cleaned with cleaning agents specially designed for the purpose, and then de-
greased.
Pressure Washers
When washing the vehicle with a high-pressure cleaner, the instructions for
use of the equipment must be observed. This particularly applies to instruc-
tions regarding the pressure and spraying distance from the vehicle surface.
Maintain a sufficiently large spraying distance to the parking aid sensors and
soft materials such as rubber hoses or insulation material »
.
WARNING■
When washing your vehicle in the winter: Water and ice in the braking
system can affect the braking efficiency – risk of accident!■
Take care when cleaning the underbody or the inside of the wheel wells -
there is a risk of injury from sharp metal parts!
CAUTION
■ Do not wash the vehicle in direct sunlight, do not exert pressure on the body
while washing. The temperature of the washing water should be no more than
60 °C max. - otherwise there is a risk of damaging the vehicle paint.■
Before driving through a car wash fold in the exterior mirrors - risk of dam-
age.
■
For vehicles with roof antenna the antenna rod should be unscrewed before
driving through a car wash - there is a risk of damage.
CAUTION
Washing the vehicle with high-pressure cleaners■Films should not be washed with any high-pressure cleaners - risk of dam-
age.■
Do not aim the water jet directly at the lock cylinders or the door or opening
joints when washing the vehicle in the winter – there is a risk of freezing.
■
The sensors of the parking aid can be sprayed only for a short time and there
must be a minimum distance of 10 cm - there is a risk of damage.
114General Maintenance

■Windows and door mirrors
■ Do not clean the insides of the windows/mirrors with sharp objects - risk of
damage to the filaments or the antenna. ■ Do not use a cloth which has been used to polish the body - this could dirty
the window and impair visibility.■
Head / tail lights
■ Do not wipe head/tail lamps dry, do not use any sharp objects - risk of dam-
age to the protective coating and cracks forming on the headlamp glass cov-
ers.
■

127
The vehicle battery represents a power source for the motor to start and for
the supply of electrical consumers in the car.
Automatic shutdown of consumers - vehicle battery discharge protection
The on-board power supply system tries to prevent the vehicle battery from
discharging in the following ways when it is subject to heavy loading. ▶ By increasing the engine idle speed.
▶ Through the power limitation of certain consumers.
▶ By switching off some consumers (heated seats, heated rear window) for as
long as necessary.
Warning symbols on the vehicle batterySymbolImportanceAlways wear eye protection.Battery acid is severely caustic. Always wear gloves and eye pro-
tection.Keep fire, sparks, open flames and lit cigarettes well clear of the
vehicle battery.When charging the vehicle battery, a highly explosive gas mixture
is produced.Keep children away from the vehicle battery.WARNINGBattery acid is highly corrosive - it can cause injury, chemical burns or poi-
soning! Corrosive vapours in the air irritate and damage the respiratory
tract and the eyes. The following guidelines must be observed.■
Always wear protective gloves, eye and skin protection when handling
the vehicle battery.
■
If your eyes or skin come into contact with the electrolytic fluid, immedi-
ately wash the affected area for a few minutes with a lot of water. Get
medical assistance without delay.
■
Keep the vehicle battery away from people who are not completely inde-
pendent (e.g. children).
■
Do not tilt the battery otherwise battery electrolyte may flow out of the
battery vent openings.
