Towing a trailer

before negotiating a downhill section to allow the engine to also act as a
brake.
Engine overheating
Please keep a check on the coolant temperature gauge if you have to
negotiate a lengthy slope in a low gear at a high engine speed when the
outside temperature is very high ⇒page 14.
If the needle of the coolant temperature gauge moves into the right-hand
area or even the red area of the scale, reduce your speed immediately.
Stop and switch off the engine if the warning light
 in the instrument
cluster begins flashing. Wait a few minutes and check the level of coolant
in the coolant expansion bottle ⇒page 215, “Inspecting the coolant level”.
Please refer to the following guidelines ⇒page 31, “Coolant tempera-
ture/coolant level ”.
The coolant temperature can be reduced by switching on the heating.
Any increase in the cooling effect of the coolant fan through shifting down
a gear and increasing the engine speed is not possible since the fan
speed is independent of the engine speed. One should also not drop a
gear for this reason when towing a trailer as long as the engine can
manage the slope without any drop in speed.
Detachable towing device*
The detachable ball head of the towing device is stowed in the spare
wheel well in the luggage compartment.
An instruction for correct installation and removal of the ball head of the
towing device is supplied with the ball head
Inspect the ball head to ensure that it is properly locked each time before
setting off. The inspection is performed by turning the closed locking lever
downwards. If the locking lever can only be turned approx. 5°, the locking
mechanism is O.K. After the inspection pull the locking lever back again
to its stop. The towing device must not be used, if it does not wish to close
or the locking lever turns slightly in the closed position.
WARNING
Do not use any aids or tools for installing or removing the ball
head. This might result in damage to the locking mechanism to the

Note
•Before a long drive we recommend that you purchase and carry with
you engine oil which complies with the specification for your vehicle.
Consequently, you will always have the correct engine oil for refilling.
•We recommend using a preservative from the Škoda original accesso-
ries offered by your Škoda dealer.
•For further information - see Service Schedule.
Inspecting the engine oil level
The dipstick indicates the level of oil in the engine.
Checking the oil level
– Park the vehicle on a horizontal surface.
– Switch the engine off. – Open the bonnet
⇒ in “Working in the engine compart-
ment” on page 209.
– Wait a few minutes and pull out the oil dipstick.
– Wipe off the dipstick with a clean cloth and insert it again fully.
– After this, once again withdraw the dipstick and read off the oil level ⇒fig. 161 .
Oil level within range
– You must not top up the oil.
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 213. 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.

Inspecting and Replenishing213
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
The warning light in the instrument cluster will indicate whether the oil
level is too low
⇒page 28. In this case, check the oil level as soon as
possible. Top up with an appropriate quantity of oil.
WARNING
Read and observe the warning notes ⇒page 209, “Working in the
engine compartment” before working in the engine compartment.
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 obtain professional assistance from a Škoda dealer.
Replenishing engine oil
– Inspect the oil level ⇒page 212.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒page 211, “Engine oil specifications”.
– Inspect the oil level ⇒page 212.
– Carefully screw on the cap of the filler opening and push the dipstick in fully.
The location of the engine oil filler opening is shown in the illustration of
the engine compartment ⇒page 210.
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 209, “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 212,
fig. 161 . 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.
Changing engine oil
The engine oil must be changed at the intervals stated in the Service
Schedule or according to the service interval indicator ⇒page 16.
WARNING
•Only carry out the engine oil change, if you have the required
professional knowledge!
•Read and observe the warning notes ⇒page 209, “Working in
the engine compartment” before working in the engine compart-
ment.
•Let the engine cool down - risk of burning from hot oil.

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 left.
– Switch the engine off. – Open the bonnet
⇒ in “Working in the engine compart-
ment” on page 209.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 162. 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 28. We nevertheless
recommend inspecting the coolant level directly at the reservoir from time
to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the
system. You should not merely top up the coolant in the reservoir. It is also
important to have the cooling system inspected without delay by a Škoda
dealer.
Losses can only occur through the pressure relief in the cap of the coolant
expansion bottle which is completely free of leaks if the coolant boils as a
result of overheating and is forced out of the cooling system.
WARNING
Read and observe the warning notes ⇒page 209, “Working in the
engine compartment” before working in the engine compartment.
Caution
One should contact a Škoda dealer as soon as possible if the source of
overheating itself cannot be determined and removed, since there may be
grave damage to the engine.

Fuses and light bulbs251
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 Škoda
dealer if a newly inserted fuse blows again after a short time.
Fuse assignment
Certain electrical components are only standard on certain vehicle model
versions or only suppliable as optional equipment for certain models.
