warning lights SKODA SUPERB 2011 Owner´s Manual

Exterior mirrors
You have to have additional exterior mirrors fitted if you are not able to see
the traffic behind the trailer with the standard rear-view mirrors. National legal
requirements must be observed.
Headlights
The front of the vehicle can be lifted when a trailer is being towed and the
headlights can dazzle other road users.
Adjust the headlight setting on the headlight range control » page 68, Operat-
ing the lights and the instrument illumination .WARNING■
Incorrect or improperly connected electrical installation can cause acci-
dents and serious injury due to electric shock.■
Work on the electrical system must only be carried out by specialist ga-
rages.
■
Never directly connect the trailer's electrical system with the electrical
connections for the tail lights or other current sources.
■
After coupling the trailer and connecting up the power socket, check the
rear lights on the trailer to ensure they are working.
■
The handbrake on the towing vehicle must be applied when coupling and
uncoupling the trailer.
■
Never use the safety eyelet for towing!
CAUTION
Incorrect or improperly connected electrical installations may cause malfunc-
tion of the entire vehicle electronics.
Loading a trailer
The vehicle/trailer combination must be balanced, whereby the maximum per-
missible drawbar load must be utilised. If the drawbar load is too low, it jeop-
ardises the performance of the vehicle/trailer combination.
Distribution of the load
Distribute the load in the trailer in such a way that heavy items are located as
close to the axle as possible. Secure the items from slipping.
The distribution of the weight is very poor if your vehicle is unladen and the
trailer is laden. Maintain a particularly low speed if you cannot avoid driving
with this combination.
Tyre pressure
Correct the tyre inflation pressure on your vehicle for a “full load” » page 198.
Trailer load
The permissible trailer load must not be exceeded under any circumstan-
ces » page 228 , Technical data .
The details given in the vehicle's technical documentation always take prece- dence over the details in the Owner's Manual.
The trailer loads specified apply only to altitudes up to 1,000 metres above
mean sea level.
The engine output falls as altitude increases, as does the ability to climb.
Therefore, for every additional 1,000 m in height (or part), the maximum per-
missible towed weight must be reduced by 10 %.
The towed weight comprises the actual weights of the (loaded) towing vehicle
and the (loaded) trailer.
The trailer and drawbar load information on the type plate of the towing
equipment are merely test data for the towing equipment. The vehicle-specific
values are detailed in the vehicle documents.WARNING■ The maximum permissible axle and drawbar load and the permissible
weight of the trailer must not exceed - this could cause an accident!■
A sliding cargo can significantly adversely affect stability and driving safe-
ty - there is a risk of accident!
Towing a trailer
Driving speed
For safety reasons, do not drive faster than 80 km/h when towing a trailer.
Immediately reduce your speed as soon as even the slightest swaying of the
trailer is detected. Never attempt to stop the trailer from “swaying” by acceler-
ating.
Brakes
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply
the brakes gently at first and then brake firmly. This will avoid brake jolts re-
sulting from the trailer wheels locking.
On downhill sections shift down a gear in good time to also use the engine as
a brake. 
171Hitch and trailer

Engine overheating
The speed must be reduced immediately if the needle for the coolant tempera-
ture gauge moves into the right-hand area or the red area of the scale.
Stop and switch off the engine if the warning light 
in the instrument cluster
illuminates.
The following guidelines must be observed » page 36, 
Coolant .
The coolant temperature can be reduced by switching on the heating.WARNING■ Always drive particularly carefully with the trailer.■Adapt your speed to the conditions of the road surface and to the traffic
situation.
CAUTION
If you tow a trailer frequently, you should also have your vehicle inspected be-
tween service intervals.
Trailer stabilisation (TSA)
The trailer stabilisation is an extension of the stabilisation control that works
in conjunction with the counter-steering assistance to reduce the amount the
trailer "sways".
After turning on the ignition, the ESC warning light 
in the instrument cluster
illuminates for about 2 seconds longer than the ABS warning light.
Function requirements for trailer stabilisation. The trailer was shipped from the factory or purchased from the ŠKODA
genuine accessories.
The ESC is active. (Warning lights 
or 
do not illuminate in the instru-
ment cluster).
The trailer is electrically connected to the towing vehicle by means of the
trailer socket.
The speed is higher than approx. 60 km/h.
The trailer has a rigid drawbar.
WARNING■ The increased safety offered by the trailer stabilisation must not tempt
you to take greater risks than otherwise.■
Avoid abrupt and sudden driving and braking manoeuvres - there is a risk
of accidents.
CAUTION
■ The trailer stabilisation need not be able to correctly detect all of driving sit-
uations.■
Light trailers that sway are not always detected and therefore stabilised ac-
cordingly by the trailer stabilisation.
■
Release the pressure on the accelerator pedal if the system is being regula-
ted.
Note
The trailer stabilisation works for both braked and unbraked trailers.
Anti-theft alarm system
When the vehicle is locked, the alarm is activated when the electrical connec-
tion to the trailer is interrupted.
Always switch off the anti-theft alarm system before a trailer is coupled or un-
coupled » page 55 .
Conditions for including a trailer in the anti-theft alarm system. The vehicle is factory fitted with an anti-theft alarm system and towing
equipment.
The trailer is electrically connected to the towing vehicle by means of the
trailer socket.
The electrical system of the vehicle and trailer is functional.
The vehicle is locked with the vehicle key and the anti-theft alarm system
is activated.
CAUTION
For technical reasons, trailers with rear LED lights cannot be connected to the
anti-theft alarm system.172Driving

Read and observe and on page 186 first.
The windscreen washer fluid reservoir is located in the engine compart-
ment » Fig. 165 .
This contains the cleaning fluid for the windscreen or rear window and for the
headlight cleaning system.
The capacity of the reservoir is about 3 litres or about 5.5 litres on vehicles that
have a headlight cleaning system 1)
.
Clear water is not sufficient to intensively clean the windscreen and head-
lights. We recommend using clean water together with a screen cleaner from
the range of ŠKODA Original Accessories (with antifreeze in winter), which will
remove any stubborn dirt.
The washing water should always be mixed with antifreeze in winter even if
the vehicle has heated windscreen washer nozzles.
Under exceptional circumstances, methylated spirits can also be used if no
screen cleaner with antifreeze is available. The concentration of methylated
spirits must not be more than 15 %. The freeze protection at this concentration
is sufficient only to -5 °C. 
1)
In some countries, 5.5 ltr. applies for both variants.
188General Maintenance

CAUTION■Under no circumstances must radiator antifreeze or other additives be added
to the windscreen washer fluid.■
If the vehicle is fitted with a headlight cleaning system, only cleaning prod-
ucts which do not attack the polycarbonate coating of the headlights must be
added to the windscreen washer fluid.
■
Do not remove the filter from the windscreen washer fluid reservoir when re-
filling, as this may cause contamination of the liquid transportation system,
leading in turn to a windscreen washer system malfunction.

The engine has been factory-filled with a high-grade oil that can be use
throughout the year - except in extreme climate zones.
The engine oils are undergoing continuous further development. Thus the in- formation stated in this Owner's Manual is only correct at the time of publica-
tion.
ŠKODA Service Partners are informed about the latest changes by the manu-
facturer. We therefore recommend that the oil change be completed by a
ŠKODA Service Partner.
The specifications (VW standards) stated in the following can be indicated sep-
arately or together with other specifications on the bottle.
The oil capacities include oil filter change. Check the oil level when filling; do
not over fill. The oil level must be between the markings » page 190.

The coolant consists of water with coolant additive. This mixture guarantees
antifreeze protection, protects the cooling/heater system against corrosion
and prevents lime formation.
Vehicles exported to countries with a mild climate are already factory-filled
with a coolant which offers antifreeze protection down to about -25 ℃. In
these countries, the concentration of coolant additive should be at least 40%.
Vehicles exported to countries with a cold climate are already factory-filled
with a coolant which offers antifreeze protection down to about -35 °C. In
these countries, the concentration of coolant additive should be at least 50%.
If a higher concentration of antifreeze is required for climatic reasons, the con-
centration of coolant additive can be increased up to a maximum of 60% (anti-
freeze protection down to approx. -40 °C).
When refilling, only use the same antifreeze identified on the coolant expan-
sion vessel » Fig. 167 on page 192 .
WARNINGThe engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en- gine compartment » page 186.
CAUTION
■
 Do not continue if for some reason it is not possible to fill with coolant un-
der the current circumstances! Switch off the engine and seek assistance from
a specialist garage.■
If the expansion tank is empty, do not top up with coolant. The system could
ventilate - there is a risk of engine damage, 
do not continue driving! Switch
off the engine and seek assistance from a specialist garage.
■
The concentration of coolant additive in the coolant must never be under
40%.
■
Over 60% of coolant additive in the coolant reduces the antifreeze protec-
tion and cooling effect.
■
A coolant additive that does not comply with the correct specifications can
significantly reduce the corrosion protection.
■
Any faults resulting from corrosion may cause a loss of coolant and can con-
sequently result in major engine damage!
■
Do not fill the coolant above the mark
A
» Fig. 167 on page 192 .
■
If a fault causes the engine to overheat, we recommend visiting a specialist
garage, as otherwise serious engine damage may occur.
■
Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.
■
Never cover the radiator - there is a risk of the engine overheating.

191Inspecting and replenishing

SymbolMeaning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.WARNINGThere is risk of injuries, poisoning, chemical burns, explosions or fire when
working on the battery and on the electrical system. It is essential to com-
ply with the generally applicable rules of safety as well as the warning in-
structions outlined below.■
Keep the vehicle battery away from people who are not completely inde-
pendent, especially children.
■
Do not tilt the battery otherwise battery electrolyte may flow out of the
battery vent openings. Protect your eyes by wearing safety goggles or a
face shield – risk of blindness!
■
Always wear protective gloves, eye and skin protection when handling
the vehicle battery.
■
The battery acid is strongly corrosive and must, therefore, be handled
with the greatest of care.
■
Corrosive fumes in the air irritate the air passages and lead to conjunctivi-
tis and inflammation of the air passages in the lungs.
■
Battery acid corrodes dental enamel and, if it comes into contact with the
skin, causes deep wounds that take a long time to heal. Repeated contact
with diluted acids causes skin diseases (inflammations, ulcers, skin cracks).
■
If any battery acid comes into contact with your eyes, rinse the affected
eye immediately with clean water for several minutes and consult a doctor
immediately!
■
Splashes of acid on your skin or clothes should be neutralised as soon as
possible using soap suds and then rinsed with plenty of water. If you swal-
low battery acid, consult a doctor immediately!
WARNING■ It is prohibited to work with naked flames or lights.■It is prohibited to smoke or carry out any activities that produce sparks.■
Never use a damaged vehicle battery – risk of explosion!
WARNING (Continued)■Never charge a frozen or thawed vehicle battery – risk of explosion and
chemical burns!■
Replace a frozen vehicle battery.
■
Never jump-start vehicle batteries with insufficient acid levels – risk of
explosion and chemical burns.
WARNING■ When you charge a battery, hydrogen is released, and a highly explosive
gas mixture is also produced. An explosion can be caused through sparkling
over during unclamping or loosening of the cable plug while the ignition is
on.■
Creating a bridge between the poles on the battery (e.g. with a metal ob-
ject or cable) creates a short circuit - risk of melting the lead bars, and risk
of explosion, battery fire and acid splashes.
■
Avoid creating sparks when working with cables and electrical devices.
Strong sparking represents a risk of injury.
■
Before carrying out any work on the electrical system, switch off the en-
gine, the ignition and all electrical components and disconnect the negative
terminal (-) on the battery.
CAUTION
Improper handling of the battery can lead to damage. We recommend having
all work on the vehicle battery carried out by a specialist garage.
CAUTION
■ The vehicle battery must only be disconnected if the ignition is switched off,
otherwise the vehicle's electrical system (electronic components) can be dam-
aged. When disconnecting the battery from the electrical system, first of all
disconnect the negative terminal (-) of the battery, and then the positive ter-
minal (+).■
When connecting the battery to the electrical system, first of all connect the
positive terminal (+) of the battery, and then the negative terminal (-). Under
no circumstances must the battery cables be connected incorrectly – risk of a
cable fire.
■
Ensure that battery acid does not come into contact with the bodywork – risk
of damage to the paintwork.
■
Do not place the battery in direct daylight in order to protect the vehicle bat-
tery housing from the effects of ultra-violet light. 
194General Maintenance

NoteWe recommend having the vehicle checked by a specialist garage in order to
ensure full functionality of all electrical systems.
Automatic load deactivation
Read and observe
and on page 194 first.
The vehicle voltage control unit automatically prevents the battery from dis-
charging when the battery is put under high levels of strain. This may be no-
ticed from the following.
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where necessary, large convenience consumers such as seat heaters and
rear window heaters have their power limited or are shut off completely in
the event of an emergency.
CAUTION
■ Despite such intervention by the vehicle electric system management, the
vehicle battery may be drained. For example, when the ignition is switched on
a long time with the engine turned off or the side or parking lights are turned
on during longer parking.■
Consumers that are supplied via a 12-V power socket can cause the vehicle
battery to discharge when the ignition is switched off.
Note
Driving comfort is not impaired by consumers being deactivated. The driver is
often not aware of it having taken place.Wheels

propriate care should therefore be taken when driving – risk of accident!■
For reasons of driving safety, do not replace tyres individually.
■
Never exceed the maximum permissible load bearing capacity of moun-
ted tyres.
■
Never exceed the maximum permissible speed for the mounted tyres.
■
An incorrect wheel alignment at the front or rear impairs handling.
■
Unusual vibrations or pulling of the vehicle to one side could be a sign of
tyre damage. If there is any doubt that a wheel is damaged, immediately re-
duce your speed and stop! If no external damage is evident, drive slowly
and carefully to the nearest specialist garage to have the vehicle checked.
WARNINGInformation regarding tyre damage or wear■Never use tyres if you do not know anything about the condition and age.■

For towing a braided tow rope is to be used » Fig. 187-
 .
The following guidelines must be observed when towing.
Vehicles with manual transmission may be towed in with a tow bar or a tow
rope or with the front or rear wheels raised.
Vehicles with automatic transmission may be towed in with a tow bar or a tow
rope or with the front wheels raised. If the vehicle is raised at rear, the auto-
matic gearbox is damaged!
Driver of the tow vehicle
›
Engage the clutch gently when starting off or depress the accelerator partic-
ularly gently if the vehicle is fitted with an automatic gearbox.
›
Only then, approach correctly when the rope is taut.
The maximum towing speed is 50 km/h.
Driver of the towed vehicle›Switch on the ignition so that the steering wheel is not locked and so that
the turn signal lights, windscreen wipers and windscreen washer system can
be used.›
Take the vehicle out of gear or move the selector lever into position N if the
vehicle is fitted with an automatic gearbox.
Please note that the brake servo unit and power steering only operate if the
engine is running. If the engine is not running, significantly more physical force
is required to depress the brake pedal and steer the vehicle.
If using a tow rope, ensure that it is always kept taught.
Both drivers should be familiar with the problems which might possibly occur while a vehicle is being towed. Unskilled drivers should not attempt to tow in
another vehicle or to be towed in.
The vehicle must be transported on a special breakdown vehicle or trailer if it
is not possible to tow in the vehicle in the way described or if the towing dis-
tance is greater than 50 km.
WARNING■ When towing, respect the national legal provisions, especially those
which relate to the identification of the towing vehicle and the vehicle be-
ing towed.■
When towing, exercise increased caution.
■
For towing no spiral tow rope is to be used » Fig. 187- 
, the towing eye
may unscrew out of the vehicle - there is a risk of accidents.
■
The tow rope should not be twisted - there is a risk of accidents.
CAUTION
■ Do not tow start the engine – there is a risk of damaging the engine and the
catalytic converter. The battery from another vehicle can be used as a jump-
start aid » page 211 , Jump-starting .■
If the gearbox no longer contains any oil, your vehicle must only be towed
with the front axle raised clear of the ground or on a breakdown vehicle or
trailer.
■
To protect both vehicles when tow-starting or towing, the tow rope should
be elastic. Thus one should only use plastic fibre rope or a rope made out of a
similarly elastic material. 

Some manual skills are required to change a bulb. For this reason, we recom-
mend having bulbs replaced by a specialist garage or seeking other expert help
in the event of any uncertainties.
› Switch off the ignition and all of the lights before replacing a bulb.
› Faulty bulbs must only be replaced with the same type of bulbs. The designa-
tion is located on the light socket or the glass bulb.
› A stowage compartment for replacement bulbs is located in a plastic box in
the spare wheel or underneath the floor covering in the boot.
WARNING■ Always read and observe the warnings before completing any work in the
engine compartment » page 186.■
Accidents can be caused if the road in front of the vehicle is not suffi-
ciently illuminated and the vehicle cannot or can only be seen with difficul-
ty by other road users.
■
Bulbs H7 H8 and H15 are pressurised and may burst when changing the
bulb - risk of injury! We therefore recommended wearing gloves and safety
glasses when changing a bulb.
■
Gas discharge bulbs (xenon bulbs) operate with a high voltage, professio-
nal knowledge is required – risk of death!
■
Switch off the respective vehicle light when changing the bulb.
CAUTION
Do not take hold of the glass bulb with naked fingers (even the smallest
amount of dirt reduces the working life of the light bulb). Use a clean cloth,
napkin, or similar.
Note
■ This Owner's Manual only describes the replacement of bulbs where it is pos-
sible to replace the bulbs on your own without any complications arising. Other
bulbs must be replaced by a specialist garage.■
We recommend that a box of replacement bulbs always be carried in the ve-
hicle. Replacement bulbs can be purchased from ŠKODAOriginal Accessories.
■
We recommend having the headlight settings checked by a specialist garage
after replacing a bulb in the main beam, low beam or fog lights.
■
In case of failure of a xenon gas discharge lamp or an LED diode, visit a spe-
cialist garage.
