Skoda Octavia Owner's Manual page 201

The coolant additive percentage in the coolant must be at least 40%.
The coolant additive may be increased to a maximum of 60%.
The correct mixing ratio of water and coolant additive is to be checked if nec-
essary by a specialist garage or is to be restored if necessary.
The description of the coolant is shown in the coolant expansion reservoir
» Fig. 207 on page 199.
WARNING
The engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en-
gine compartment » page 194.
The coolant is harmful to health.
■
Avoid contact with the coolant.
■
Coolant vapours are harmful to health.
■
Never open the end cover of the coolant expansion reservoir while the
■
engine is still warm. The cooling system is pressurized!
When opening the end cover of the coolant expansion reservoir, cover it
■
with a cloth to protect your face, hands and arms from hot steam or hot
coolant.
If any coolant splashes into your eyes, immediately rinse out your eyes
■
with clear water and contact a doctor as soon as possible.
Always keep the coolant in the original container, safe from people who
■
are not completely independent, especially children - there is a danger of
poisoning!
If coolant is swallowed, consult a doctor immediately.
■
Never spill operating fluids over the hot engine - risk of fire.
■
CAUTION
If for some reason it is not possible to top up the coolant under the current
■
circumstances, do not continue driving! Switch off the engine and seek as-

sistance from a specialist garage.
If the expansion tank is empty, do not top up with coolant. The system could
■
aerate - risk of engine damage,

gine and seek assistance from a specialist garage.
The amount of coolant additive in the coolant must never be allowed to be
■
less than 40 %.
Over 60 % of coolant additive in the coolant reduces the antifreeze protec-
■
tion and coolant effectiveness.
A coolant additive that does not comply with the correct specification can
■
significantly reduce the corrosion protection of the cooling system.
do not continue driving! Switch off the en-
Any faults resulting from corrosion may cause a loss of coolant and can con-
■
sequently result in major engine damage.
Do not fill the coolant above the mark
■
If an error occurs, leading to the engine overheating, the help of a professio-
■
nal garage is to be sought - there is a risk of serious engine damage occurring.
Additional headlights and other attached components in front of the air inlet
■
impair the cooling efficiency of the coolant.
Never cover the radiator - there is a risk of the engine overheating.
■
Note
On vehicles that are fitted with an auxiliary heater (auxiliary heating and venti-
lation), the coolant capacity is approx. 1 l larger.
Checking the coolant level

Read and observe and
The coolant expansion bottle is located in the engine compartment.
