Warning symbols on the vehicle battery Symbol Importance
 Always wear eye protection.
 Battery acid is severely caustic. Always wear gloves and eye protec-
tion.
 Keep fire, sparks, open flames and lit cigarettes well clear of the ve-
hicle battery.
 When charging the vehicle battery, a highly explosive gas mixture is
produced.
 Keep children away from the vehicle battery. Improper handling of the vehicle battery can cause damage. We therefore recom-
mend that any work on the vehicle battery is carried out by a
ŠKODA Service Part-
ner.
There is a risk of injuries, scalding, accidents and burns when carrying out any
work on the battery and on the electrical system. For this reason, it is essential to
comply with the warning instructions stated below and with the general applica-
ble rules of safety. WARNING
■ The battery acid is strongly corrosive and must, therefore, be handled with
the greatest of care. Always wear protective gloves, eye and skin protection
when handling the vehicle battery. Corrosive fumes in the air irritate the air
passages and lead to conjunctivitis and inflammation of the air passages in
the lungs. They corrode tooth enamel. After contact with the skin, the acid
creates deep wounds which take a long time to heal. Repeated contact with
diluted acids causes skin diseases (inflammations, ulcers, skin cracks). Acids
coming into contact with water are diluted accompanied by significant devel-
opment of heat.
■ Do not tilt the battery otherwise battery electrolyte may flow out of the bat-
tery vent openings. Protect the eyes with safety glasses or a shield! There is
the danger of suffering blindness! If any battery electrolyte comes into con-
tact with your eyes, rinse the relevant eye immediately with clear water for
several minutes. Then 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 acid was
swallowed, seek immediate medical attention.
■ Keep children away from the vehicle battery.
■ 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.
■ Bridging of the poles will create a short circuit (e.g. through metal objects,
cables). Possible consequences of a short circuit: Melting of lead struts, explo-
sion and burning of the battery, jets of acid spurting out.
■ It is prohibited to work with a naked flame and light, to smoke or to carry
out any activities which produce sparks. 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 engine,
the ignition and all of the electrical components and disconnect the negative
terminal
(-) on the battery. If you wish to replace a bulb it suffices to switch off
the relevant light. ■ Never charge a frozen or thawed vehicle battery – risk of explosion and
caustic burns! Replace a frozen vehicle battery. ■ Never jump-start vehicle batteries with an electrolyte level that is too low –
risk of explosion and caustic burns. ■ Never use a damaged vehicle battery – risk of explosion! Replace a damaged
vehicle battery immediately. £

Inspecting and replenishing

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 dis-
connect the negative terminal
(-) of the battery. Then disconnect the positive ter-
minal (+).
■ When connecting the battery to the electrical system, first connect the positive
terminal (+) of the battery. Then connect the negative terminal
(-). Under no cir-
cumstances 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 battery
housing from the effects of ultra-violet light.
■ If the vehicle has not been driven for more than 3 to 4 weeks, the battery will
discharge. This is because certain electrical components consume electricity (e.
g.
control units) also in idle state. Prevent the battery from discharging by discon-
necting the battery's negative terminal or continuously charging the battery with
a very low charging current.
■ If the vehicle is frequently used for making short trips, the vehicle battery will
not have time to charge up sufficiently and may discharge. For the sake of the environment
A vehicle battery that has been removed is a special type of hazardous waste.
These must be disposed of in accordance with national legal regulations. Note
You should replace batteries older than 5 years. Ð Checking the battery electrolyte level
Fig. 104
Vehicle battery: Electrolyte level
indicator
First read and observe the introductory information and safety warn-
ings on page 115.
We recommend you have the electrolyte level checked by a ŠKODA specialist ga-
rage from time to time, especially in the following cases.
› High outside temperatures.
› Long daily drives
› After each charge
» page 117.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called
magic eye » Fig. 104 , the electrolyte level can be determined by looking at the
change in colour.
Air bubbles can influence the colour of the indicator. For this reason carefully
knock on the indicator before carrying out the check.
› Black colour – electrolyte level is correct.
› Colourless or light yellow colour – electrolyte level too low, the battery must be
replaced. Note
■ The battery electrolyte level is periodically checked by a
ŠKODA Service Partner
as part of the Inspection Service. ■ For technical reasons, on vehicles with the description “AGM”, the electrolyte
level cannot be checked. ■ Vehicles with a START-STOP system are fitted with a battery control unit for
checking the energy level for the recurring engine start. Ð

116 General Maintenance

›
Let all of the occupants get out.
While changing a tyre, the occupants of the
vehicle should not stand on the road (instead they should remain behind a crash
barrier).
› Switch off the engine and move the gearshift lever into
Neutral or move the
selector lever for the automatic gearbox into position N.
› Firmly apply the
handbrake.
› Remove the vehicle tool kit
» page 127 and the spare wheel » page 122, Spare
wheel from the luggage compartment. ÐChanging a wheel
First read and observe the introductory information and safety warn-
ings on page 128.
Always change a wheel on a level surface as far as possible.
›
Remove the full wheel trim
» page 122 or caps »
page 123.
› First of all slacken the anti-theft wheel bolt and then the other wheel
bolts » page 130.
› Jack up the vehicle until the wheel that needs changing is clear of the
ground » page 131 .
› Unscrew the wheel bolts and place them on a clean surface (cloth, paper, etc.).
› Remove the wheel.
› Attach the spare wheel and slightly screw on the wheel bolts.
› Lower the vehicle.
› Alternately tighten the wheel bolts opposite each other using the wheel
wrench (crosswise) and then tighten the anti-theft wheel bolt » page 130.
› Reinstall the wheel trim/wheel trim cap or the caps. Note
■ All bolts must be clean and must turn easily.
■ Under no circumstances grease or oil the wheel bolts!
■ When fitting unidirectional tyres, ensure that the direction of rotation is cor-
rect »
page 121, Unidirectional tyres . ÐSubsequent steps
First read and observe the introductory information and safety warn-
ings on page 128.
The following steps must also be performed after changing the wheel.ä
ä ›
Stow and attach the replaced wheel in the spare wheel well using a special
screw » page 122, Spare wheel.
› Stow the vehicle tool kit in the space provided.
› Check
the tyre pressure
on the installed spare wheel as soon as possible.
› Have the
tightening torque of the wheel bolts checked with a torque wrench
as soon as possible.
› Change the damaged wheel or consult a ŠKODA specialist garage about repair
possibilities. Note
■ If it is determined that the wheel bolts are corroded and difficult to turn when
changing the wheel, the bolts must be replaced before checking the tightening
torque. ■ Drive cautiously and only at a moderate speed until the tightening torque has
been checked. Ð

Always read and observe the warnings before completing any work in the en-
gine compartment » page 108, Engine compartment . CAUTION
■ Never “repair” fuses and also do not replace them with a fuse of a higher am-
perage - risk of fire! This may also cause damage at another part of the electrical
system.
■ Have the electrical system checked as quickly as possible by a ŠKODA specialist
garage if a newly inserted fuse blows again after a short time. Note
■ We recommend always carrying replacement fuses in the vehicle. A box of re-
placement fuses can be purchased from

ŠKODA Original Accessories.
■ Multiple fuses may exist for a single power consuming device.
■ Multiple power consuming devices can share a single fuse. Ð Fuses on the underside of the dash panel

Headlights 141
Changing the light bulb for side repeater turn signal lights 142
Changing light bulbs for fog lights 142
Changing the bulb for the licence plate light 143
Tail lamp assembly 143
Some manual skills are required to change a bulb. For this reason, if uncertain, we
recommend that bulbs are replaced by a ŠKODA specialist garage or other expert
help is sought.
› 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 luggage compartment. WARNING
■ Accidents can be caused if the road in front of the vehicle is not sufficiently
illuminated and the vehicle cannot or can only be seen with difficulty by other
road users.
■ Always read and observe the warnings before completing any work in the
engine compartment » page 108, Engine compartment .
■ The H4 bulb is under pressure and may explode during a lamp replacement -
risk of injury! We therefore recommended wearing gloves and safety glasses
when changing a 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, nap-
kin, or similar. ■ When removing and installing the number plate light and tail light make sure
that the paintwork of the vehicle and the tail light are not damaged. Note
■ This Owner's Manual only describes the replacement of bulbs where it is possi-
ble to replace the bulbs on your own without any complications arising. Other
light bulbs should be changed by a

ŠKODA specialist garage.
■ We recommend that a box of replacement bulbs be always carried in the vehi-
cle. Replacement bulbs can be purchased from
ŠKODAOriginal Accessories.
■ We recommend that the headlight settings are checked by a ŠKODA specialist
garage after replacing a bulb in the main or low beam.
■ LED diodes should be changed by a specialist ŠKODA garage. Ð Headlights
