CONTROLS AND EQUIPMENT

Avoid high revs and running the engine
at full load until the engine has reached its
normal operating temperature.

Do not allow the engine to idle for a
lengthy period. If the engine is running
when the car is stationary, there is not al-
ways an adequate flow of air through the
radiator. In certain circumstances, this can
result in the engine overheating and also
in engine damage.

On vehicles with a catalytic converter
the engine must not be started by tow-
ing the vehicle more than 50 m. Other-
wise, unburnt fuel can pass into the
catalytic converter and cause damage.

Before trying to start engine by tow-
ing, use the battery from another vehi-
cle for jump-starting if possible - see
page 177.
Petrol enginesThese engines are equipped with a petrol
injection system that automatically supplies
the correct fuel/air mixture at all ambient
temperatures.
The information for starting these engines
therefore applies irrespective of the outside
temperature and is the same whether the
engine is cold or at normal operating
temperature :

Do not operate throttle before and
when starting the engine.

If the engine does not start immediately,
do not operate the starter for more than 10
seconds and wait about 30 seconds before
repeating the attempt to start the engine.

If the engine is very hot, it may be nec-
essary to depress the throttle slightly after
the engine starts.

If the engine still does not start, the fuse
for the electric fuel pump may have blown -
see page 167.
Contact your Škoda Dealer in this case.
Diesel enginesGlow plug system
After switching on the Drive position (igni-
tion on), the glow warning light comes on.
Start the engine immediately after the warn-
ing light goes out.
Starting a cold engine
Ambient temperature above +5 °C:
The engine can be started immediately
without preglow. Do not operate throttle
when starting engine.
Ambient temperature below +5 °C:

Turn the key in ignition lock to position
„2“ (see page 43) - the glow warning light
comes on. It goes out after the ignition tem-
perature is reached (see page 57).
While the glow plugs are working, do not
switch on any other major electrical
components as this would place an un-
necessary load on the battery.

When the warning lamp goes out, start
the engine immediately.

58CONTROLS AND EQUIPMENTCoolant temperature, coolant
levelThe warning light comes on for a few se-
conds after switching on the ignition.
On vehicles with information display, the
warning light does not come on after switch-
ing on the ignition, only if a fault exists or a
lack or coolant.
If the warning light does not go off after this
or flashes when driving, either the coolant
temperature is too high or the coolant level
is too low.
Text in the information display*: STOP CHECK
COOLANT SERVICE MANUAL.
An audible warning signal then sounds
(peep signal 3 times).
If this happens, stop the car and switch
off the engine ; check the coolant level and
top up coolant if necessary.
If the warning light comes on, although the
coolant is at the correct level and the fan
fuse is in proper order, do not drive any
further. The engine must then also not run
in neutral. Contact a Škoda Dealer for pro-
fessional assistance.
Warning

Take care when opening the cool-
ant expansion tank. When the engine
is hot, the cooling system is pressu-
rized - risk of scalding! Allow the
engine to cool down, therefore, be-
fore unscrewing the cap.

Do not touch the fan! The fan may
switch on suddenly - even if the igni-
tion is switched off.
If the coolant is at the correct level, the rise
in temperature may be caused by a failure
of the radiator fan. Check the fuse of the
radiator fan and renew if necessary - see
page 167.
If the warning light does not go out althou-
gh the coolant is at the correct level and
the fan fuse is in proper order, do not drive
any further . Contact a Škoda Dealer for
professional assistance.
Further information is provided on pages
137 and 142.
Brake wear indicator*If this warning light comes on, contact a
Škoda Dealer to have the brake pads chec-
ked.
An audible warning signal sounds (single
peep signal).
In view of the fact that the brake wear indi-
cator monitors only the front brake pads, it
is recommended to also have the rear
brake pads or linings inspected.Fuel levelThe warning light comes on and remains
on if there are only about 7 litres of fuel in
the tank.
An audible warning signal sounds (1 beep).

126DRIVING TIPSDriving instructions
To obtain the best possible handling of ve-
hicle and trailer, please note the following
points:

Try to avoid driving with an unladen ve-
hicle and a loaded trailer. If this cannot be
avoided, only drive slowly to allow for the
unfavourable weight distribution.

As the driving stability of vehicle and trai-
ler decreases when the speed increases,
do not drive at the maximum permissible
top speed in unfavourable road, weather or
wind conditions - particularly when going
downhill.
You should in any case immediately reduce
your speed as soon as you detect even the
slightest swaying of the trailer. On no ac-
count attempt to eliminate the swaying by
accelerating!

For safety reasons, you should not drive
faster than 80 km/h (50 mph). This also
applies in countries where higher speeds
are permitted.

Apply the brakes in good time! If the
trailer is fitted with an overrun brake, apply
the brakes gently at first, then increase the
pressure. This avoids any braking shocks
caused by the wheels of the trailer block-
ing. Shift down gears in good time before
driving downhill so that the engine can act
as a brake.

If it is necessary to drive a long uphill
section in a low gear with a very high en-
gine speed and at unusually high ambient
temperatures, keep a check on the cool-
ant gauge. If the needle of the gauge moves
into the upper range of the scale, reduce
the speed of your car immediately. If the
temperature and brake fluid level warning
light flash, however, stop and allow engine
to cool down by letting it idle for a few min-
utes. Pay attention to the further informa-
tion on p. 46.

The coolant temperature can be reduced
by switching on the heater.

The cooling effect of the radiator fan
cannot be increased by changing down,
because the speed of the fan is not depend-
ent on the engine speed. You should there-
fore not change down even when towing a
trailer as long as the engine can cope with-
out the vehicle speed dropping too much.
General notes

It is advisable to have the vehicle ser-
viced between the inspection intervals
if it is used frequently for towing a trailer.

The trailer and drawbar load figures on
the data plate of the towing bracket are for
test certification only. The correct figures for
the vehicle, which may be lower than the
above figures, are given in the vehicle do-
cuments.

GENERAL MAINTENANCE
BonnetTo unlock the bonnet, pull lever below the
instrument panel on the driver’s side.
The bonnet jumps out of its lock as a result
of the spring pressure.
Note
Before opening the bonnet, ensure that the
windscreen wiper arms are not folded for-
ward otherwise the paintwork may be dam-
aged. Warning
For safety reasons, the bonnet must
always be properly closed when ve-
hicle is moving. Always check there-
fore after closing the bonnet that the
lock is engaged.
Should you notice that the bonnet lock is
not properly engaged when driving, stop the
car immediately and close the bonnet.
To open
bonnet, grasp it at the bottom of
the radiator grille, raise slightly, push the
hook in direction of arrow and raise bon-
net.
Take bonnet prop out of its catch and in-
sert it into the opening provided - see illus-
tration (on right).
To close, raise bonnet slightly and release
bonnet prop. Press prop into the fixture at
the front-end panel. Allow bonnet to drop
into the lock from a height of about 20 - 30
cm - do not press on bonnet to close it!

GENERAL MAINTENANCE
Warning
Particular care is required when per-
forming work in the engine compart-
ment!

Never open the bonnet if you see
that steam or coolant is escaping
from the engine compartment - risk
of scalding!
You must wait long enough, until the
steam or coolant has stopped escap-
ing.

Switch off engine and withdraw ig-
nition key.

Apply handbrake properly.

Move gearshift into Neutral (on
models with automatic gearbox mo-
ve selector lever into position „P“).

Allow engine to cool down.

If the engine is still warm:
- do not place your hand into the ra- diator fan, it might start suddenly.
- do not open filler cap of coolant reservoir as cooling system is
pressurized - risk of scalding.

Avoid short circuits in the electri-
cal system - particularly at the bat-
tery!

If you wish to work under the ve-
hicle, you must secure the vehicle
from rolling away and support it with
suitable supporting blocks: the car
jack is not sufficient for this - risk of
injury!

If it is necessary to carry out test
work when engine is running, there
is an additional risk from rotating
parts - e.g. ribbed belt, alternator,
radiator fan etc. - and from the high-
voltage ignition system.

Never touch the electrical cables
of the ignition system.

Absolutely avoid any jewellery,
loose items of clothing or long hair
from getting into the rotating parts of
the engine - Hazard! Therefore re-
move any jewellery beforehand, tie
up your hair and wear tight fitting
clothing.
It is essential to comply with all the
warning information given in this
manual and with the general rules of
safety when carrying out work on the
engine.
When topping up fluids, ensure that no mix-
ups occur otherwise this may cause severe
operating problems!
The floor below the car should be
inspected regularly in order to de-
tect leaks in good time. If patches of oil or other fluids are visible, the car shouldbe taken to a Škoda Dealer for an inspec-
tion.

144GENERAL MAINTENANCE
Drained coolant should not nor-mally be re-used but should be dis-
posed of by complying with environmen- tal protection regulations.
Radiator fanThe radiator fan is driven by an electric mo-
tor and controlled by a thermostatic switch
in line with the coolant temperature.
Warning
After the engine has been switched
off, the fan may continue running for
a while - even if the ignition is swit-
ched off. It may also start to run again
suddenly after a short time if
- the coolant temperature increases due to heat build-up
- when the engine is hot and the en- gine compartment is heated addi-
tionally by strong sunlight.
Special care should therefore be
taken when working in the engine
compartment.
Brake fluidThe brake fluid reservoir is located in the
left of the engine compartment.Checking fluid levelThe fluid level should always be between
the „MAX“ and „MIN“ markings on the re-
servoir.
A slight drop in the fluid level occurs when
driving as a result of wear and tear and au-
tomatic slack adjustment of the brake pads.
This is perfectly normal.
Warning
The coolant additive and the coolant
are poisonous! Do not breathe in
coolant vapours, do not swallow
coolant, avoid contact with eyes and
skin.
If coolant splashes into your eye,
rinse out immediately with clear wa-
ter and contact a doctor.
If coolant is swallowed, you should
likewise contact a doctor. The cool-
ant additive should therefore be
safely stored in the original contain-
ers out of the reach of children.
If the coolant has to be drained out
of the cooling system of the car at
any time, it should be collected,
marked and likewise stored in a safe
place.

GENERAL MAINTENANCE
Windscreen washer system
The windscreen washer reservoir is located
in the right of the engine compartment. It
holds about 3 litres, or about 5.5 litres in
the case of models with a headlight washer
system.
If the vehicle is equipped with headlight
washer system, it is necessary to only
use certain fluids which do not corrode
any polycarbonate connections.
Filling reservoirWhen topping up windscreen washer
fluid, do not remove the sieve from the
reservoir. Impurities might otherwise
affect proper operation of the wind-
screen washer system.
We recommend always adding a wind-
screen cleaner with wax-dissolving proper-
ties to the water (in winter with antifreeze
protection) as clear water is not generally
sufficient to quickly and intensively clean
the windscreen and the headlight lenses.
Refer to the mixing instructions on the wind-
screen cleaner pack.
Note
Should windscreen cleaner with antifreeze
protection not be available in exceptional
cases, it is also possible to add methylated
spirits (the concentration of methylated
spirits must not be higher than 15 %). Note
in this case, however, that the antifreeze
protection of this concentration is only down
to -5 °C at the most.
Even if your vehicle has heated windscreen
washer* nozzles, in winter you should al-
ways add antifreeze protection to the wa-
ter.
On no account use radiator antifreeze pro-
tection or other additives!
Windscreen wiper bladesThe windscreen wiper blades at the front
and rear must be in proper condition if they
are to ensure clear visibility. Wiper blades
must not be dirtied by dust, insect residues
and wax preservative.
To avoid smears, the windscreen wiper
blades should be cleaned regularly with a
windscreen cleaner. If they are very dirty,
e.g. insect residues, the wiper blades can
also be cleaned with a sponge or cloth.
If the wiper blades rub or „smear“, this may
be caused by wax residues on the wind-
screen as a result of washing the car in an
automatic car wash. For this reason, each
time after washing the car in a car wash
with wax treatment, remove the wax from
the lips of the wiper rubbers and from the
windshield and rear window.
In frosty conditions, check that the wiper
blades are not frozen to the glass before
switching the wipers on for the first time.
For safety reasons, the windscreen wiper
blades should be replaced twice a year.
Windscreen wiper blades are available
from Škoda Dealers.
