Towing a trailer
202
You must always reduce your speed immediately as soon as you detect
even just the slightest swaying of the trailer. On no account attempt to
stop the trailer from “swaying” by accelerating.
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 resulting from the trailer wheels locking. Shift down gears in good
time 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 225, “Inspecting the coolant level”.
Please refer to the following guidelines ⇒page 32, “Coolant temperature,
Coolant quantity ”.
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 around a small angle
(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.

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 shedule.
Check 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 219.
– 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. 175 .
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 223. 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 Replenishing223
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
The warning light in the instrument cluster will indicate whether the oil
level is too low
⇒page 33, “Engine oil ”. 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 219, “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 the engine off
and obtain professional assistance from a specialist garage, otherwise it
could lead to severe engine damage.
Replenishing engine oil
– Inspect the oil level ⇒page 222.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒page 221, “Engine oil specifications”.
– Inspect the oil level ⇒page 222.
– 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 219, “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 222,
fig. 175 . 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 219, “Working in
the engine compartment” before working in the engine compart-
ment.
•Let the engine cool down - risk of burning from hot oil.
•Wear an eye protection - risk of caustic burns due to oil
splashes.

Your Škoda Service Partner 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 219.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 176. 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 27. 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
specialist garage.
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 219, “Working in the
engine compartment” before working in the engine compartment.
Caution
One should contact a specialist garage as soon as possible if the source
of overheating itself cannot be determined and removed, since there may
be grave damage to the engine.

•Do not place the battery in direct daylight in order to protect the battery
housing from the effects of ultra-violet light.
For the sake of the environment
A removed battery is a special type of waste which is harmful to the envi-
ronment - contact your specialist garage regarding disposing of the
battery.
Note
Please also refer to the guidelines ⇒page 233, “Disconnecting and
reconnecting the battery”, also after connecting the battery.
Battery with a charge level indicator, the so-called
magic eye
There is a so-called magic eye ⇒fig. 179 located on the top of the battery.
The “magic eye” changes its colour in line with the charge state of and
electrolyte level in the battery.
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 specialist
garage.
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 specialist garage.
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 228, “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 specialist garage when outside
temperatures are high or when driving on long trips. You should also
check the electrolyte level ⇒page 231 each time the battery is charged.
The battery acid level will also be checked as part of the Inspection
Service.
