Oil level within range
– You may top up the oil. It is possible that the oil level may then
be within range after doing this.
Oil level within range
– You must top up the oil ⇒page 252. It is sufficient, once this
is done, to keep the oil level is within range .
It is normal for the engine to consume oil. The oil consumption may be as
much as 0.5 l/1 000 km depending on your style of driving and the condi-
tions under which you operate your vehicle. The oil consumption may be
slightly higher than this during the first 5 000 kilometres.
One should therefore check the oil level at regular intervals, preferably
every time after the fuel tank is filled or after driving for long stretches.
We recommend maintaining the oil level within the range if the engine
has been operating at high loads, for example during a lengthy motorway
trip during the summer months, towing a trailer or negotiating a high
mountain pass, but not above this .
The warning light in the instrument cluster* will indicate ⇒page 38,
“Engine oil level* ” whether the oil level is too low. In this case, check
the oil level as soon as possible. Top up with an appropriate quantity of oil.
Caution
•The oil level must on no account extend beyond the range . Danger
of damaging the catalytic converter.
•Do not continue your journey if for some reason it is not possible
under the conditions prevailing to top up with oil. Switch of the engine
and contact and obtain professional assistance from a specialist
garage.
Replenishing engine oil
– Inspecting the engine oil level ⇒page 251.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒page 250, “Engine oil specifications”.
– Inspect the oil level ⇒page 251.
– Carefully screw on the cap of the filler opening and push the dipstick in fully.
WARNING
•Avoid dripping oil onto hot parts of the engine when topping up
will oil - a risk of fire!
•Read and observe the warning notes ⇒ page 248, “Working in
the engine compartment” before working in the engine compart-
ment.
For the sake of the environment
The oil level must on no account be above the range ⇒page 251. Oil
will otherwise be drawn in through the crankcase ventilation and may pass
through the exhaust system to atmosphere. The oil may combust in the
catalytic converter and damage it.

Coolant
The cooling system is filled at the works with coolant (purple in colour),
which complies with the specification TL-VW 774 F.
We recommend that you use the same coolant additive - G12 PLUS
(purple in colour).
Please contact your Škoda dealer if you have any questions regarding the
coolant or if you wish to fill up with a different coolant.
Your Škoda dealer can also supply you with the correct coolant additives.
Caution
•Other coolant additives may cause operational problems which,
in particular, involves significantly reducing the anticorrosion effect.
•Any faults or problems resulting from corrosion may cause a loss
of coolant and, as a consequence of this, result in major engine
damage.
Inspecting the coolant level
The coolant expansion bottle is located in the engine compart-
ment on the right.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compart-
ment” on page 248.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 194 . The coolant level when the engine is cold must lie
between the (MIN) and (MAX) markings. The level may
also rise slightly above the (MAX) marking when the
engine is warm.
If the coolant level in the reservoir is too low, this is indicated by the
warning light in the instrument cluster  ⇒ page 35. We nevertheless

Air bubbles can influence the colour of the “magic eye”. For this reason
carefully knock on the “magic eye” before carrying out the check.
•Green colour - the battery is adequately charged.
•Dark colour - the battery has to be charged
•Colourless or yellow colour - have the battery checked by a Škoda
dealer.
Batteries, which are more than 5 years old, must be replaced. We recom-
mend you have the electrolyte level inspected and adjusted to the correct
level or the battery replaced if necessary by a Škoda dealer.
Caution
If the vehicle has not been driven for more than 3 to 4 weeks, the battery
will discharge because certain electrical components consume electricity
(e.g. control units) also in idle state. You can prevent the discharging of
the battery by disconnecting the negative terminal or charging the battery
constantly with a very low charging current. Please also refer to the notes
when working on the battery ⇒page 258, “Working on the battery”.
Inspecting the electrolyte level
The battery is practically maintenance-free under normal operating
conditions. We do, however, recommend that you have the electrolyte
level inspected from time to time by a Škoda dealer when outside temper-
atures are high or when driving on long trips. You should also check the
electrolyte level ⇒page 260 each time the battery is charged.
The battery acid level will also be checked as part of the Inspection
Service.
Operation in winter
The battery has to provide greater amounts of electricity during the winter.
It also has only part of the initial power output at low temperatures that it
has at normal temperatures.
A discharged battery may already freeze at temperatures just below
0°C.
We therefore recommend that you have the battery checked by a Škoda
dealer before the start of the winter, and recharged if necessary.
WARNING
Never charge a frozen or thawed battery - risk of explosion and
caustic burns. Replace a frozen battery.
Charging the battery
A properly charged battery is essential for reliably starting
the engine.
– Read the warning notes ⇒ in “Working on the battery” on
page 258 and ⇒.
– Switch the ignition and all electrical components off.
– Only for “quick-charging”: Disconnect both battery cables (first of all “negative”, then “positive”).
– Carefully attach the terminal clamps of the charger to the battery terminals (red = “positive”, black = “negative”).

Securing wheels against being stolen*
You need a special adapter for slackening the safety
wheel bolts.
– Pull off the full wheel trim/cap from the wheel hub or cap from
the safety wheel bolt.
– Push the adapter with its toothed side into the inner toothing of the safety wheel bolt right down in such a way
that only the outer hexagon is jutting out ⇒fig. 211.
– Push the wheel wrench fully onto the adapter .
– Slacken the wheel bolt, or tighten it firmly ⇒page 279.
– Reinstall the full wheel trim/wheel cap after removing the adapter or place the cap onto the safety wheel bolt. – Have the
tightening torque checked with a torque wrench as
soon as possible. Steel and light alloy wheels must be tight-
ened to a tightening torque of 120 Nm.
The safety wheel bolts on vehicles fitted with them (one safety wheel bolt
per wheel) can only be loosened or tighten up by using the adapter
provided.
It is meaningful to note the code number hammered into the rear side of
the adapter or the rear side of the safety wheel bolts. You can obtain a
replacement adapter from a Škoda dealer, if necessary, by quoting this
number.
We recommend that you always carry the adapter for the wheel bolts with
you in the vehicle. It should be stowed in the vehicle tool kit.
Caution
Damage can occur to the adapter and safety wheel bolt if the safety wheel
bolt is tightened up too much.
Note
The set of safety wheel bolts can be obtained from your Škoda dealer.
Jump-starting
Initial steps
You can use the battery of another vehicle for jump-starting yours if the
engine does not start because the battery on your vehicle is flat. You will
require jump-start cables for this purpose.

Fuses and light bulbs289
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Caution
•Never attempt to “repair” fuses and also do not replace them with a
fuse of a higher amperage - 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
specialist garage if a newly inserted fuse blows again after a short time.
Fuse cover in engine compartment
The fuse box in the engine compartment exists in two
different versions. You can determine which version your
vehicle is fitted with after removing the fuse cover at the
location of the fuses.
For particular model versions, the battery must be removed
before removing the fuse cover ⇒page 258.
Removing fuse cover
– Move the circlips ⇒fig. 218 as far as the stop, the symbol
 appears behind the circlip and remove the cover.
Installing fuse cover
– Position the fuse cover on the fuse box and push the circlips as far as the stop - the symbol
 is visible behind the
circlip.
