Inspecting and Replenishing
214
Inspecting the coolant level
The coolant expansion bottle is loca ted in the engine compartment on
the right.
– Switch the engine off.
– Open the bonnet ⇒page 209, “Working in the engine compartment”.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 189 .
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 31. We nevertheless recommend inspecting
the coolant level directly at th e 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 expan-
sion bottle which is completely free of leak s if the coolant boils as a result of over-
heating 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 specialist garage as soon as possible if the source of over-
heating 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 ⇒fig. 189 and unscrew the cap carefully by turning it to the left
⇒ .
– Top up the coolant.
– Screw the cap tight until it is heard to lock.
The coolant which you use for replenishing the system, must comply with one
specific specification ⇒page 213, “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 specialist garage.
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.

Fuses and light bulbs

Electrically adjustable seats are protected by automatic circuit breakers, which
switch on again automatically after a few seconds after the overload has been
eliminated.
Bulbs
Changing bulbs
The relevant lamp must always be switch ed off before a light bulb is replaced.
Defect light bulbs should only be replaced with light bulbs of the same type. The
designation is located on the li ght socket or the glass bulb.
Changing certain bulbs is not something wh ich you can do yourself, but requires to
be done by a specialist. Other parts of the vehicle must be removed in order to
change the light bulbs. This applies, in particular, to bulbs which can only be
reached from the engine compartment.
We therefore recommend that you have any bulbs changed by a Škoda Service
Partner or, in exceptional cases, by ca lling on other professional assistance.
Please note that the engine compartment is a hazardous area ⇒page 209,
“Working in the engine compartment”.
We recommend that you carry the set of light bulbs with you which was delivered
in your vehicle. Replacement light bulbs
17) are available at specialist garages.
The set of light bulbs can be stowed in the locable box in the spare wheel.
Fitted with a xenon headlight
Change of light bulbs on Xenon lights (low beam lights, parking lights and main
beam lights) should be undertaken by a specialist garage.
