Towing a trailer
Technical requirements
The towing device must satisfy certain technical require-
ments.
Your vehicle is designed primarily for transporting persons and luggage.
It can, however, also be used for towing a trailer - provided certain tech-
nical equipment is fitted.
If your vehicle has already been supplied with a factory-fitted towing
device then everything that is necessary for towing a trailer in technical
terms, and in terms of the law, has already been taken into account.
Your vehicle is fitted with a 13-pin power socket for the electrical connec-
tion between the vehicle and trailer. If the trailer which you wish to tow has
a 7-pin connector , you can use a suitable adapter cable. You can obtain
such an adapter from a Škoda dealer.
This work must be carried out in accordance with the manufacturer's
specifications if a towing device is retrofitted.
Škoda dealers are familiar with details relating to retrofitting a towing
device and for any necessary modifications to the cooling system.
General Maintenance
There are a number of points to pay attention to when
towing a trailer.
Trailer load
The permissible trailer load must on no account be exceeded.
You can negotiate appropriately steeper inclines and descents if you do
not make full use of the permissible trailer load.
The trailer loads specified only apply for altitudes up to 1 000 metres
above mean sea level. The fact that the engine power output drops with
increasing height due to a lowering of air pressure and thus the ability to
climb, means that the towed weight must be reduced by 10% for every
further increase of 1 000 metres in height above sea level. The towed
weight is the weight of the (laden) vehicle and the (laden) trailer together.
One should take this into account before driving up to higher altitudes.
The trailer and drawbar load information on the type plate of the
towing device are merely test data for the towing device The data
relating to your vehicle, which is often less than this test data, can
be found in your vehicle registration documents or in the brochure -
Technical Data.
Distribution of the load
Distribute the load in the trailer in such a way that any heavy items are
located as close as possible to the axle. Secure the items to prevent them
slipping.
You can make full use of the permissible drawbar load indicated on the
ball head of the towing device, but you must not exceed this.
WARNING
We recommend that you have the towing device installed by a
Škoda dealer. He is familiar with all the relevant details relating to
retrofitting such equipment. There is a risk of an accident if the
towing device is not properly fitted.

Note
The location of the inspection points in the engine compartment of petrol
and diesel engines is practically identical.
Engine oil
Engine oil specifications
The grade of engine oil should be selected in accordance
with precise specifications.
The engine of your vehicle has been factory-filled with a high-grade oil
which you can use throughout the year - except in extreme climatic
regions.
You can mix various oils together with each other when refilling with oil.
This does not, however, apply for models with flexible service intervals
(QG1).
Engine oils are, of course, undergoing continuous further development.
Thus the information stated in this Owner's Manual is only correct at the
time of publication.
Škoda dealers are constantly informed by Škoda Auto about current
changes. This why you should always have engine oil changed by your
Škoda dealer. Engine oil specifications for vehicles with fixed service intervals
(QG2)
Engine oil specifications for models with flexible service intervals
(QG1).
For further information - see Service Schedule.
Caution
Only the above-mentioned oils may be used on vehicles with flexible
service intervals (QG1). We recommend always refilling with oil of the
same specification since this will maintain the properties of the oil. In
exceptional cases, you must top up only once engine oil complying with
Specification VW 502 00 (only for petrol engines) or Specification VW 505
01 (only for diesel engines) to maximum 0.5 litres. You must not use other
engine oils - risk of engine damage!

Inspecting and Replenishing207
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Caution
The oil level must on no account extend beyond the range . Danger of
damaging the catalytic converter.
Replenishing engine oil
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres
⇒page 205, “Engine oil specifications”.
– Inspect the oil level ⇒page 206.
– Carefully screw on the cap of the filler opening and push the dipstick in fully.
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.
The location of the engine oil filler opening is shown in the illustration of
the engine compartment ⇒page 204.
For the sake of the environment
The oil level must on no account be above the range ⇒page 206,
fig. 156 . 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 17.
Caution
You must not pour any additives into the engine oil - risk of engine
damage!
For the sake of the environment
•You must on no account pour oil into the ground or into the sewage
system.
•In view of the problems involved in properly disposing of old oil, the
material, equipment and the knowledge required for such work, we recom-
mend that you have the oil and oil filter change carried out by your Škoda
dealer.
WARNING
Avoid dripping oil onto hot parts of the engine when topping up will
oil - a risk of fire!

WARNING
Store old oil in a safe place out of the reach of children and unau-
thorized persons until you dispose of it properly.

Inspecting and Replenishing209
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
– Open the bonnet ⇒ in “Working in the engine compart-
ment” on page 203.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 157. 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.
One should contact a Skoda 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.
Replenishing the coolant
– Switch the engine off.
– Allow the engine to cool down. – Place a cloth over the cap of the coolant expansion reservoir
⇒page 208, fig. 157 and unscrew the cap carefully by
turning it to the left ⇒.
– Top up the coolant.
– Screw on the cap tight until it is heard to lock.
The coolant which you use for replenishing the system, must comply with
certain specifications ⇒page 208, “Coolant”. Do not use an alternative
additive if the coolant additive G12°PLUS is not available in exceptional
cases. Just top up the system with water and as soon as possible arrange
adjustment to correct the mixing ratio of water and coolant additive again
by a Škoda dealer.
Only use fresh coolant for topping up the system.
Do not fill up over the “MAX” marking! Excess coolant which is heated up
is forced out of the cooling system through the pressure relief valve in the
cap of the coolant compensation bottle.
Wait until the engine has cooled down for a system which has suffered a
major loss of coolant before pouring in coolant. This is necessary to avoid
engine damage.
Do not continue your journey if for some reason it is not possible
under the conditions prevailing to top up with coolant. Switch off the
engine and obtain professional assistance from a Škoda dealer.
WARNING
•The cooling system is pressurized! Do not open the cap of the
coolant expansion bottle if the engine is still hot - risk of
scalding!
