WARNING■The use of open flames and light should be avoided.■Smoking and radio triggering activities should be avoided.■
Never use a damaged vehicle battery – risk of explosion!
■
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.
CAUTION
■ Improper handling of the vehicle battery may cause damage.■Ensure that battery acid does not come into contact with the bodywork – risk
of damage to the paintwork.■
If the vehicle has not been driven for more than 3 to 4 weeks, the battery will
discharge. Prevent the battery from discharging by disconnecting the battery's
negative terminal 
or continuously charging the battery with a very low
charging current.
■
Do not place the battery in direct daylight in order to protect the vehicle bat-
tery housing from the effects of ultra-violet light.
■
If the vehicle is frequently used for making short trips, the vehicle battery
will not have time to charge up sufficiently and may discharge.
Note
■ We recommend having all work on the vehicle battery carried out by a spe-
cialist garage.■
You should replace batteries older than 5 years.

Checking the battery electrolyte level
Fig. 210
Vehicle battery: Electrolyte level
indicator
Read and observe and on page 201 first.
On vehicles with a vehicle battery fitted with a colour indicator, the electrolyte
level can be determined by looking at the change in colour of this display.
Air bubbles can influence the colour of the indicator. For this reason carefully
knock on the indicator before carrying out the check.
Check
Black colour – electrolyte level is correct.
Colourless or light yellow colour – electrolyte level too low, the battery must
be replaced.
For technical reasons, on vehicles with the description “AGM”, the electrolyte
level cannot be checked.
Vehicles with the START STOP system are fitted with a battery control unit for
checking the energy level for recurring engine starts.
We recommend that you have the acid level checked regularly by a specialist
garage, especially in the following cases. ▶ High external temperatures.
▶ Longer day trips.
▶ After each charge. 

202General Maintenance

Winter time
The vehicle battery only has a proportion of the starting power in lower tem-
peratures. A discharged vehicle battery may already freeze at temperatures
just below 0 °C .
We therefore recommend that you have the battery checked and, if necessary,
recharged by a specialist garage before the start of the winter.
Note
The battery acid level is also checked regularly by a specialist garage as part of
the inspection service.
Charging
Read and observe
and on page 201 first.
A properly charged vehicle battery is essential for reliably starting the engine.A charging operation can be performed if the following conditions are satis-
fied.
The engine is turned off.
The ignition is switched off.
All consumers are turned off.
The bonnet is open.
“Fast charging” with high currents
›
Disconnect both battery cables (first of all “negative”, then “positive”).
›
Attach the terminal clamps of the charger to the battery terminals (red =
“positive”, black = “negative”).
›
Plug the mains cable of the charger into the power socket and switch on the
device.
›
After charging has been successful: Switch off the charger and remove the
mains cable from the power socket.
›
Only then disconnect the charger's terminal clamps.
›
Reconnect the cables to the battery (first of all “positive”, then “negative”).
Charging with low voltages
It is not necessary to disconnect the cables from the battery if you recharge
the vehicle battery, for example from a mini-charger.
Refer to the instructions of the charger manufacturer .
A charging current of 0.1 multiple of the total vehicle battery capacity (or low-
er) must be used until full charging is achieved.
The vent plugs of the vehicle battery should not be opened for charging.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 metal ob-
jects - cables) creates a short circuit - risk of damage to the battery, explo-
sion and burning of the battery, jets of acid spurting out.
■
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 
.
■
“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
■
We therefore recommend that vehicle batteries be “rapidly charged” by a
specialist garage.
CAUTION
On vehicles with the START/STOP system or additional heating (auxiliary heat-
ing), do not connect the pole terminal of the charger directly to the negative
terminal of the vehicle battery, but rather only to the engine earth » page 219,
Jump-starting using the battery from another vehicle .
Replacing
Read and observe
and on page 201 first.
The new vehicle battery must have the same capacity, voltage, current and
size as the original battery. Suitable vehicle battery types can be purchased
from a specialist garage.
We recommend you have the battery replaced by a specialist garage.

CAUTION
■ Disconnect the vehicle battery only with the ignition turned off - there is a
risk of damaging the electrical system of the vehicle.■
Under no circumstances must the battery cables be connected incorrectly –
risk of a cable fire.
Note
■ After disconnecting and re-connecting the vehicle battery, we recommend
having the vehicle checked by a specialist to ensure that the full functionality
of all electrical systems is guaranteed.■
The data of the multi-function display will be reset.
Automatic load deactivation
Read and observe
and on page 201 first.
The vehicle's electrical system automatically prevents the battery from dis-
charging when the battery is being heavily used. This manifests itself by the
following. ▶ The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
▶ Where appropriate large convenience consumers, e.g. seat heaters, rear win-
dow heaters, have their power limited or in case of emergency shut off com-
pletely.
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 which are supplied via a 12 V socket can cause the vehicle battery
to discharge when the ignition is switched off.
Note
Driving comfort is not disrupted by any shutting off of consumers. Often the
driver is not aware of it having taken place.204General Maintenance

213Emergency equipment, and self-help

Raising the vehicle›Insert the crank 7 into the mount on the jack 6» page 212.›
Support the base plate of the jack with its entire surface resting on level
ground and ensure that the lever is positioned vertically to the jacking point
» Fig. 222 .
›
Use the crank to raise the jack until its claw encloses the bar » Fig. 222.
›
Continue to raise the jack until the wheel is just lifted off the ground.
WARNING■
If the wheel has to be changed on a slope, first of all block the opposite
wheel with a stone or similar object to prevent the vehicle from unexpect-
edly rolling away.■
Secure the base plate of the lifting jack with suitable means to prevent
possible moving. A soft and slippery ground under the base plate may move
the lifting jack, causing the vehicle to fall down. It is therefore always nec-
essary to place the lifting jack on a solid surface or use a wide and stable
base. Use a non-slip base (e.g. a rubber foot mat) if the surface is smooth,
such as cobbled stones, tiled floor, etc.
■
Only attach the lifting jack to the attachment points provided for this pur-
pose.
■
Always raise the vehicle with the doors closed.
■
Never position any body parts, such as arms or legs under the vehicle,
while the vehicle is raised with a lifting jack.
■
When the vehicle is raised, never start the engine.
CAUTION
It is important to ensure that the jack is correctly attached to the bar of the
lower beam, as otherwise there is a risk of damage to the vehicle.
Remove the wheel / fix
When changing a wheel, the following instructions must be followed.
›
Remove the full wheel trim or the caps of the wheel bolts.
›
First of all slacken the anti-theft wheel bolt and then the other wheel bolts.
›
Jack up the vehicle until the wheel that needs changing is clear of the
ground.
›
Unscrew the wheel bolts and place them on a clean surface (cloth, paper,
etc.).
›
Remove the wheel carefully.
›
Attach the wheel and slightly screw on the wheel bolts.
›
Lower the vehicle.
› Tighten the wheel bolts opposite each other using the wheel wrench (alter-
nating crosswise). Tighten the anti-theft wheel bolt last.›
Replace the wheel trim and the caps.
When fitting unidirectional tyres, ensure that the direction of rotation is cor-
rect » page 207 .
All bolts must be clean and must turn easily.
If it is established when changing a wheel that the wheel bolts are corroded and difficult to move, then these must be replaced.
Under no circumstances grease or oil the wheel bolts!
WARNINGUndo the wheel bolts only a little (about one turn) as long as the vehicle
has not yet been jacked up. Otherwise the wheel could become loose and
fall off.
Follow-up tasks
After changing the wheel, the following work must be carried out.
›
Stow the replaced wheel in the wheel well and secure it with a special screw.
›
Stow the tool kit in the space provided and secure using the band.
›
Check the tyre pressure on the installed wheel as soon as possible.
›
Have the tightening torque of the wheel bolts checked with a torque wrench
as soon as possible.
After changing the wheel, the tyre pressure must be adjusted. In vehicles with
tyre pressure monitoring, save tyre pressure values » page 165.
Replace the damaged wheel or consult a specialist garage about repair op-
tions.
The prescribed tightening torque of the wheel bolts is 120 Nm.
WARNING■
If the wheel bolts are tightened to a too low tightening torque, the rim
can come loose when the car is moving. A tightening torque which is too
high can damage the bolts and threads and this can result in permanent
deformation of the contact surfaces on the rim.■
Drive cautiously and only at a moderate speed until the tightening torque
has been checked.

Starting engine
›
Start the engine on the vehicle providing the power and allow it to idle.
›
Start the engine of the vehicle with the discharged battery.
›
If the engine does not start, terminate the attempt to start the engine after
10 seconds and wait for 30 seconds before repeating the process.
›
Remove the jump-start cables exactly in the reverse sequence as for attach-
ing.
Both batteries must have a rated voltage of 12 V. The capacity (Ah) of the bat-
tery supplying the power must not be significantly less than the capacity of
the discharged battery in your vehicle.
Jump-start cables
Only use jump-start cables which have an adequately large cross-section and
insulated terminal clamps. Observe the instructions of the jumper lead manu-
facturer.
Positive cable – colour coding in the majority of cases is red.
Negative cable – colour coding in the majority of cases is black.WARNING■
Do not clamp the jump-start cable to the negative terminal of the dis-
charged battery. There is the risk of detonating gas seeping out the battery
being ignited by the strong spark which results from the engine being star-
ted.■
The non-insulated parts of the terminal clamps must never touch each
other – risk of short circuit!
■
The jump-start cable connected to the positive terminal of the battery
must not come into contact with electrically conducting parts of the vehicle
– risk of short circuit!
■
Route the jump-start cables so that they cannot be caught by any rotat-
ing parts in the engine compartment.

A braided tow rope must be used for towing » Fig. 226- 
.
When towing, the following guidelines must be observed.
Vehicles with manual transmission may be towed in with a tow bar or a tow
rope or with the front or rear wheels raised. 
220Do-it-yourself

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! If possible, the vehicle should be towed with the
engine running or at least with the ignition on.
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.
General information for the towing process
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.
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.
Attach the tow rope or the tow bar to the towing eyes » page 221 or
» page 222 to the detachable ball head of the towing equipment » page 167 .
WARNING■
When towing, exercise increased caution.■Spiral tow ropes must not be used for towing » Fig. 226-  , the towing
eye may unscrew out of the vehicle - risk of accident.■
The tow rope should not be twisted - risk of accident.
CAUTION
■ Do not start engine by towing - there is a risk of damaging the engine parts.
The battery from another vehicle can be used as a jump-start aid » page 219,
Jump-starting .■
There is always a risk of excessive stresses and damage resulting at the
points to which you attach the tow rope or tow bar when you attempt to tow a
vehicle which is not standing on a paved road.
Note
We recommend using a tow rope from ŠKODA Original Accessories available
from a ŠKODA Partner.
