Starting-off and Driving
124
Starting the engineGeneral You can only start the engine only using an original ignition key.•
Place the gearshift lever into neutral (or place the selector lever to the position
P or N in the case of an automatic gearbox)
and put on the handbrake firmly before
starting the engine.•
The clutch pedal should be fully depressed when starting the engine which
means that the starter only has to crank the engine.•
Let go of the key as soon as the engine starts otherwise there may be damage
to the starter. The engine running noises ma
y louder at first be louder for a short time after
starting the cold engine until oil pressure
can be built up in the hydraulic valve
clearance compensation. This is quite no
rmal and is not an operating problem.
If the engine does not start ... You can use the battery of anothe
r vehicle as a jump-start aid
⇒page 252.
It is only possible to tow-start vehicles
fitted with a manual gearbox. The tow-
starting distance must not be more than 50 metres
⇒page 256.
WARNING
•
Never run the engine in non ventilat
ed or enclosed areas. The exhaust
gases of the engine contain besides the odorless and colourless carbon monoxide a poisonous gas - hazard!
Carbon monoxide can cause uncon-
sciousness and death.•
Never leave your vehicle unattended with the engine running.Caution
•
The starter may only be operated (ignition key position ), if the engine is not
running. If the starter is i
mmediately operated
after switching off the engine, the
starter or the engine can be damaged.
•
Avoid high engine revolutions, full throttle and high engine loads as long as the
engine has not yet reached its normal oper
ating temperature - risk of damaging the
engine!•
Vehicles which are fitted with an exhaus
t gas catalytic conver
ter should not be
tow-started over a distance of more than 50 metres.
For the sake of the environment
Never warm up the engine when the vehi
cle is standing. Drive off right away.
Through this the engine reaches its operating temperature more rapidly and the pollutant emissions are lower.Petrol enginesThese engines are fitted with a starter system which selects the correct fuel/air mixture for every external air temperature.•
Do not operate accelerator befo
re and when starting engine.
•
Interrupt the attempt at starting after 10 seconds if the engine does not start
right awayand wait for about 30 seconds before repeating the attempt.•
It is possible that the fuse on the electrical fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary
⇒page 258.
•
Contact the nearest specialist garage to obtain professional assistance.
It may be necessary, if the engine is
very hot
, to slightly depress the accelerator
after the engine has started.Diesel enginesGlow plug system Diesel engines are equipped with a glow plug system, the preglow period being controlled automatically in line with the coolant temperature and outside temper-ature. The preglow indicator light

Contact the nearest specialist garage to obtain professional assistance.
Starting the engine after the fuel tank has run dry It may take longer than normal to start the
engine after refuelling if the fuel tank has
run completely dry - up to one minute. This is because the fuel system must first of all be filled while the attempting to start the engine.Switching off the engine– The engine can be switched off by turning the ignition key from posi-
tion into

.
WARNING
•
Never switch off the engine before the
vehicle is stationary - risk of acci-
dent!•
The brake booster only operates when the engine is running. Greater
physical effort for braking is required
when engine is switched off. Because
if you do not stop as normal, this can cause an accident and severe injuries.
Caution
you should not switch the engine off right
away at the end of yo
ur journey
after the
engine has been operated for a lengthy peri
od at high loads but should be allowed
it to run at idling speed for about 2 minutes
. This prevents any accumulation of heat
when the engine is switched off.
Note
•
The radiator fan may conti
nue running for a further 10
minutes or
so after the
engine and the ignition have
been switched off. The coolant fan may, however, also
switch on again after some time if the
coolant temperature rises because of an
accumulation of heat in the engine or
if the engine is warm and the engine
compartment is additionally
heated by strong sunlight.
•
This is why particular care is required when carrying out any work in the engine
compartment
⇒page 225, “Working in the engine compartment”.
Shifting (manual gearbox)Shift into reverse only when the vehicle is
stationary. Depress the clutch pedal and
hold it fully depressed. Wait a moment be
fore engaging reverse gear in order to
avoid any shift noises.

should be attached to folding arms. Adjust
the mirrors so that they provide you with
an adequate field of view to the rear. Headlights Before starting off with a hitched trailer, also check the setting of the headlights. Alter the setting as necessary with th
e aid of the headlight beam adjuster
⇒ page 63. Detachable ball head The ball rod is detachable on vehicles which feature a factory-fitted towing device. It is stowed together with separate fitting instructions in the spare wheel well in the luggage compartment of the vehicle. Further information on the towing device
⇒page 210.
Note
•
We recommend that you also have yo
ur vehicle inspected between service
intervals if you tow a trailer frequently.•
The handbrake on the towing vehicle
must be put on when coupling and
decoupling the trailer.Driving Tips Particular caution is required when towing a trailer.– Do not, as far as possible, drive
with your vehicle unladen and the
trailer laden.
– Do not make full use of the legal maximum speeds. This applies in
particular to downhill sections.
– Apply the brakes in good time.– Keep a check on the coolant temper
ature gauge if the outside temper-
ature is high.
Distribution of weight The distribution of the weight is very poor
if your vehicle is
unladen and the trailer
is laden. Maintain a particularly low speed if you cannot avoid driving with this combination. Driving speed Do not drive faster than 80 km/hour for safety reasons. This also applies for coun- tries in which higher speeds are allowed. The fact that the driving stability of the vehicle + trailer combination reduces with increasing speed means that the legally allowed speed should not be used when there are unfavourable road, weather or wind
conditions, particul
arly near accident
black spots. You must always reduce your speed immedi
ately 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 down-
hill 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 18, “Coolant temperature gauge”.
If the needle of the coolant temperature gauge moves into the right-hand area or even the red area of the scale, reduce yo
ur speed immediately. Stop and switch off
the engine if the warning light
 in the instrument cluste
r begins flashing. Wait a
few minutes and check the level of coolant in the coolant expansion bottle ⇒ page 229, “Inspecting the coolant level”. Please refer to the following guidelines
⇒page 36, “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

also protects the cooling and heating system from corrosion. It also prevents the formation of scale and significantly increases the boiling point of the coolant. You must therefore not reduce the concentr
ation of antifreeze agent in the coolant
by adding water, also not during the summ
er months or in countries with a warm
climate.
The concentration of coolant additive in the coolant must be at least
40%. You can increase the amount of antifreeze
in the coolant if a higher concentration
of antifreeze is necessary for climatic
reasons but only up to 60% (antifreeze
protection down to approx. -40°C). The an
tifreeze protection tails off above that
concentration. Vehicles exported to countries with a co
ld climate (e.g. Sweden, Norway, Finland)
are already factory-filled with a coolant wh
ich offers antifreeze protection down to
about -35°C. In these countries the concentr
ation of coolant additive should be at
least 50 %. Coolant The cooling system is factory-filled with co
olant (purple in colour), which complies
with the specification TL-VW 774 G. We recommend that you use the same c
oolant additive - G12 PLUS-PLUS (purple
in colour) for toppi
ng up the system.
Please contact an authorised Škoda Service Partner if you have any questions regarding the coolant or if you wish to fill up with a different coolant. An authorised Škoda Service Partner can al
so supply you with the correct coolant
additives.
Caution
•
Other coolant additives may cause operational problems which, in partic-
ular, involves significantly redu
cing the anticorrosion effect.
•
Any faults or problems resulting from corrosion may cause a loss of
coolant and, as a consequence of th
is, result in major engine damage.
Inspecting the coolant levelThe coolant expansion bottle is loca
ted in the engine compartment on
the right. – Switch the engine off. – Open the bonnet
⇒
page 224.
– Check the level of coolant in the coolant expansion bottle
⇒
fig. 212
.
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 36, “Coolant temperat
ure/ Coolant quantity
”.
We nevertheless recommend in
specting 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 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 225, “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
⇒
page 229, fig. 212
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 228. 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 ad
justment 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.
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!
•
The coolant additive and thus all of the coolant is harmful to your health.
Avoid contact with the coolant. Coolant vapours are also harmful to the health. It is important, therefore, to always safely store any coolant additive in its original container out of the reach of children - risk of poisoning!•
If any splashes of coolant get into yo
ur eyes, rinse out
your eyes immedi-
ately with clear water and contact a doctor as soon as possible.•
You should also consult a doctor without delay if you have inadvertently
swallowed coolant.
Caution
Do not continue your journey if for some reason it is not possible under the conditions prevailing to top up with coolant. Switch of the engine and contact

and obtain professional assistance from a specialist garage.
For the sake of the environment
Do not re-use coolant if it is necessary to
drain the coolant in the system. It should
be collected and disposed of in comp
liance with environmental protection
regulations.

. The level must
be between the “MIN” and “MAX” markings.
A slight drop in the fluid level results when driving due to normal wear-and-tear and automatic adjustment of the br
ake pads, and is perfectly normal.
There may be an indication of a leak in the brake system, however, if the fluid level drops significantly within a short time or if it drops below the “MIN” marking. If the brake fluid level is too low, this is indicated by the warning light
⇒page 40, “Brake
system
” lighting up in the instru

stop immediately and
do not drive any further! Obtain professional assistance.
WARNING
•
Read and observe the warning notes
⇒page 225, “Working in the engine
compartment” before working in the engine compartment.•
If the fluid level has dropped below
the MIN marking, do not drive any
further - risk of accident! Obtain professional assistance.Replacing brake fluidBrake fluid absorbs moisture. This causes the fluid to absorb moisture from the surrounding air over a period of time. Excessive water in the brake fluid may be the cause of corrosion in the brake system. Th
e water content also lowers the boiling
point of the brake fluid.
This is why brake fluid must be replaced every two
years. One may only use new genuine brake fluid
from Škoda Auto. The specification for
the brake fluid is “FMVSS 116 DOT 4”.
