SKODA OCTAVIA TOUR 2004 1.G / (1U) Owner's Manual

120DRIVING TIPS

Do not switch off the ignition when driv-
ing.

Do not overfill engine with oil - see page
140.

Do not tow start vehicle for more than
50 m - see page 179.
Warning
Due to the high temperatures which
can occur in catalytic converters in
very unfavourable conditions, the
vehicle should not be parked in such
a way that the catalytic converter can
come into contact with inflammable
materials.
Note
Even if the emission control system is op-
erating perfectly properly, there may be a
sulphurous exhaust smell in certain engine
operating conditions. This depends on the
sulphur content in the fuel being used.
Quite often this can be remedied by select-
ing another brand of fuel or filling up with
unleaded premium petrol.
Trouble-free operation of the
emission
control system is decisive for environmen-
tally friendly operation of the vehicle.
That is why it is important to note the fol-
lowing points:

Vehicles fitted with a catalytic converter
must only be driven on unleaded petrol -
see page 128.

Never drive until the fuel tank is comple-
tely empty on vehicles fitted with a catalytic
converter. The irregular fuel supply can
cause misfiring. This allows unburnt fuel in-
to the exhaust system which can cause
overheating and damage to the catalytic
converter.

If misfiring, a loss of power and rough
engine running occur when driving, this
may be caused by a fault in the ignition
system. In this case, uncombusted fuel can
get into the exhaust system and thus pass
to the atmosphere. In addition, the catalytic
converter may be damaged as a result of
overheating. Reduce your speed immedi-
ately and have the fault rectified at the near-
est Škoda Dealer. General notes


The wear of the brake pads depends to
a great extent on the driving conditions and
your style of driving. Consequently, it may
also be necessary to have the thickness of
the brake pads inspected at a Škoda Dealer
between the intervals stated in the Service
Schedule, particularly if your car is driven
frequently in towns or over short distances,
or in a very sporty manner.

Change down in good time when driv-
ing downhill, in order to make use of the
engine braking effect. This relieves the
strain on the brake system. When the bra-
kes are applied, do not keep them on con-
tinuously, apply and release the brakes al-
ternately.

Under certain operating conditions, for
example after driving through water, after
heavy rain or after washing the vehicle, the
braking effect may be retarded by wet, or
in winter iced-up brake discs and pads - the
brakes must be dried out first by applying
the footbrake.
Brakes

121
DRIVING TIPS
The full braking effect may also be delayed
when the car has been driven for some time
on heavily salted roads without using the
brakes, because the layer of salt on the
discs and pads has to be removed first.Warning
If a front spoiler, full-size wheel trims
etc., are retrofitted, it is necessary to
ensure that the flow of air to the front
brakes is not restricted - otherwise
the brakes may overheat.
Brake booster
The braking force boosts the pressure,
which you generate with the brake pedal.
The necessary pressure is only generated
when the engine is running. Warning
The brake booster only operates
when the engine is running.
Never switch off the engine before
the vehicle is stationary.
In the case that the brake booster is
not operating - e.g. because the vehi-
cle has to be towed or because there
is damage to the brake booster - the
brake pedal has to be depressed with
a significantly greater force, in order
to balance out the missing brake
boosting effect.Because if you do not stop as nor-
mal, this can cause an accident and
severe injuries.
Brake Assist*
The Brake Assist boosts the brake servo
effect during a brake application in a haz-
ardous situation and is able in this way to
assist the rapid build-up of brake pressure.
In emergency situations the majority of car
drivers do apply the brakes in time, but not
with the brake pedal force which is neces-
sary for achieving maximum deceleration.
Valuable braking distance is lost as a result!The Brake Assist is activated as soon as the
brake pedal is depressed very rapidly. A hig-
her brake servo assistance than is usual in
normal brake applications, is then available.
Consequently, it is possible to build up
within a very short time the brake pressure
which is required for achieving maximum
deceleration with only a correspondingly
slight counterforce on the brake pedal.Depress the brake pedal further for achiev-
ing the shortest possible braking distance. Do
not reduce the foot pressure on the pedal!The Brake Assist is able in this way to help
you in critical situations by building up the
brake pressure more rapidly and shorten-
ing the stopping distance. The advantages
offered by the ABS are fully exploited by the
Brake Assist. As soon as the brake pedal is
released, the Brake Assist function is swit-
ched off then automatically and the usual
service brake function is again available.
Warning

The Brake Assist is also not in a
position to overcome the physical
limits which apply to the braking dis-
tance.

This is something you should re-
member particularly when driving on
smooth or wet road surfaces.

Adapt your style of driving always
to the road condition and the traffic
situation. The increased safety which
the Brake Assist offers you must not
lead you to take any safety risk!

122DRIVING TIPSAnti-lock brake system (ABS)*The ABS plays a major part in increasing
the active safety of the vehicle.
The big advantage when compared with a
conventional brake system is that even
during a full brake application on a slippery
road surface the best possible steerability
is retained for the road condition because
the wheels do not lock.
However, one must not expect the ABS
system to shorten the braking distance
under all conditions.
How the ABS system works
An automatic test procedure is carried out
once the car has reached a speed of about
20 km/h. A pump noise may be audible for
about 1 second during this check.
When the turning speed of a wheel reaches
a level which is too low for the vehicle speed
and it tends to lock, the brake pressure to
this wheel is reduced. The brake pressure
is controlled individually for each wheel.
This ensures that the braking action is even
and that driving stability is retained to the
maximum possible extent.This control process makes itself felt by
a pulsing movement of the brake pedal
and is accompanied by noises. This is done
deliberately as a warning to the driver that a
wheel or wheels are in the locking range. The
brake pedal should remain depressed to en-
able the ABS to offer ideal control within this
range - on no account pump the brake pedal!
Warning
The ABS system can also not over-
come the physical limits. This has to
be born in mind, particularly on slip-
pery or wet roads. When the ABS is
operating in the control range, your
speed should immediately be adap-
ter to road and traffic conditions.
The increased amount of safety avail-
able should not tempt you into tak-
ing risks.
If a fault occurs in the ABS system, this is
indicated by a warning lamp - see page 60. Warning
If a fault exists, only the normal brake
system is operational. You should
drive to a Škoda Dealer as soon as
possible. Adapt your speed and driv-
ing style to the changed circum-
stances as the extent of the damage
to the ABS system is not known.
Electronic differential lock (EDL)*Cars fitted with the anti-lock brake system
(ABS)* can be equipped in addition with an
electronic differential lock.
The EDL system makes it much easier or,
in deed, at all possible to move off, accel-
erate and drive uphill even on unfavourable
road surfaces.
The EDL operates automatically - in other
words without any action on the part of the
driver.
It monitors the speed of the driven wheels
using the sensors of the ABS system.
If the road surface is slippery on one side,
a difference in speed exists between the
driven wheels. It is then necessary to pro-
duce more throttle, for example, when mov-
ing off on a hill, on a slippery road surface
etc. The EDL function compensates for the
difference in speed by braking the wheel
which is slipping and transmits the power
through the differential to the other driven
wheel.
This control process makes itself notice-
able by characteristic noises.

123
DRIVING TIPS
In order to achieve the optimal effect of
the EDL system, depress the accelera-
tor pedal and the clutch when starting
off to match road conditions.Warning
When accelerating on a smooth road
surface, for example on ice and
snow, depress the accelerator care-
fully.
The driven wheels may slip despite
the EDL and thus affect the driving
stability of the car.
The EDL is switched off automatically if
unusually severe stresses occur. The car
can continue to be driven and has the same
characteristics as a car without EDL. That
is why no indication is provided if the EDL
is switched off.
The EDL switches on again automatically
as soon as the brake has cooled down.
If the ABS warning lamp comes on, see
page 60, there might also be a fault in the
EDL. Drive to a Škoda Dealer as soon as
possible! Warning
Your driving style should always be
adapted to the condition of the road
and the traffic situation. The addi-
tional safety offered by the EDL must
not tempt you into taking a safety
risk!
Engine braking control (EBC)*The EBC operates in conjunction with the
ABS. It is intended to prevent the driven
wheels of the car being excessively sharply
braked when „braking with the engine“ as
a result of releasing the accelerator or shift-
ing down on a smooth road surface. The
EBC automatically increases the engine
speed in order to maintain optimal steer-
ability of the car even when „braking with
the engine“.
The four-wheel drive system of your car re-
quires no manual intervention on your part.
The force is distributed to the driven wheels
automatically and is optimally matched to
the handling of the car and to the particu-
lar road conditions.
The four-wheel drive concept is designed
for high engine output and provides your
car with excellent drivability both in normal
road conditions as well as in extreme con-
ditions such as driving on snow and ice.
It is important, however, to pay attention to
the following safety information:
All-wheel drive*

124DRIVING TIPSWarning
Your style of driving should always
be matched to the condition of the
road and the traffic situation. The
enhanced safety offered by the four-
wheel drive and ABS systems must
not tempt you to take any risks re-
garding your safety!
The braking power of the car is lim-
ited by the adhesion of the tyres and
is no different than that of a car with
front-wheel drive.
You should therefore not be tempted
to drive at too high a speed even
though the car still provides good
acceleration on smooth and slippery
road surfaces.It is particularly important to note on
wet road surfaces that the front wheels
may aquaplane at high speeds. In con-
trast to a vehicle fitted only with front-
wheel drive, the start of aquaplaning
is not indicated by the engine sud-
denly revving up. For this reason, do
not drive at too high a speed, but al-
ways match your speed to the road
conditions.
Use of winter tyresFour-wheel drive already offers good vehi-
cle traction in wintry road conditions with
the standard tyres. It is nevertheless rec-
ommended to fit winter or all-weather tyres
to all four wheels in order to improve trac-
tion and braking. For further information -
refer to page 157.Use of snow chainsSnow chains must also be fitted to a vehi-
cle with four-wheel drive if the use of snow
chains is mandatory. Snow chains must
only be fitted to the front wheels. For fur-
ther information regarding snow chains -
refer to page 157. The car is intended mainly for the transpor-
tation of persons and luggage, but it can
also be used to tow a trailer if the appropri-
ate technical equipment is fitted.
Detachable ball head*

Refer to the enclosed instructions for
attaching and detaching the ball head.
For further information - refer to p. 157.Towing a trailer

125
DRIVING TIPS
Technical requirements

If the car is supplied with a factory-fitted
towing bracket, all that is technically and
legally necessary for towing a trailer has
already been taken into account.

If the trailer to be towed has a 7-pin con-
nector, you can obtain an adapter cable
from Škoda Dealers.

Škoda Dealers are acquainted with the
details of retrofitting a towing bracket and
modifying the cooling system. You should
therefore have a towing bracket fitted by a
Škoda Dealer. Operating instructions


The permissible trailer weights must on
no account be exceeded.

The trailer weights stated are only ap-
plicable for altitudes up to 1000 m above
mean sea level (MSL). As the engine out-
put and thus the climbing ability drops due
to the decreasing air density, the weight of
vehicle and trailer must also be reduced by
10 % for each further 1000 m or part the-
reof.
Take this fact into account when driving at
high altitudes.

You should make full use of the maxi-
mum permissible drawbar weight indicated
on the ball head of the towing bracket, but
do not exceed it.

The load carried in the trailer should be
distributed so that any heavy objects are
placed as close as possible to the axle,
taking into account the permissible trailer
weight and drawbar load. The objects
should also be secured to prevent them
slipping.

Select the tyre pressure of the car for full
loads and also check the pressure of the
trailer tyres.

The headlight beam control of the car
should be set to match the particular load
conditions.

The handbrake of the car should be ap-
plied when hitching up and unhitching the
trailer.
Inspect the ball head to ensure that
it is properly locked each time before
setting off.
The inspection is performed by turn-
ing the closed locking lever down-
wards.
If the locking lever can only be turned
approx. 5°, the locking mechanism is
OK.
After the inspection pull the locking
lever back again to its stop.
The towing device must not be used,
if it does not wish to close or the
locking lever turns slightly in the clo-
sed position.

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
Filling the tankThe fuel filler neck is inserted into the rear
right body panel.
The fuel tank holds about 55 litres
(4x4* - 63 litres).
Notes
The fuel filler flap can be opened from the
driver’s seat* - see page 65.
On this version the fuel cap cannot be
locked separately.
A sticker with data is affixed to the fuel filler
flap - see page 181.When refuelling, the filler cap can be in-
serted at the flap.
After refuelling, fit on the filler cap tight until
it is heard to click. After this, close the filler
flap.
If your car is not fitted with a remote re-
lease for the fuel filler flap at the driv-
er’s seat*, the following instructions
apply:
Use the car key to unlock the filler cap of
the fuel filler neck by turning it to the left
and unscrew it.
When refuelling, the filler cap can be in-
serted at the flap.
After refuelling, screw the filler cap tight until
it is heard to click. Lock the filler cap by
turning the key of the car to the right, with-
draw the key and close the fuel filler flap.
As soon as the petrol pump at the
filling station switches off automati-
cally for the first time after being prop- erly used, the fuel tank is „full“. Do notfill in any more petrol otherwise the ex-pansion chamber in the tank will be filled
and fuel might flow out when it warms up.
Note
Never run the fuel tank completely empty
on models fitted with a catalytic con-
verter. The irregular fuel supply may re-
sult in misfiring and uncombusted fuel
may get into the exhaust system. This
can cause overheating and damage to
the catalytic converter.
Warning
Observe any statutory regulations
when carrying a reserve canister of
fuel. For safety reasons, it is recom-
mended that you do not carry a re-
serve canister in the car. In the event
of an accident, the canister could be
damaged and fuel spillage could oc-
cur.

128GENERAL MAINTENANCE
FuelPetrol enginesUnleaded petrol conforming to DIN EN
228 RON 91, 95 and 98
1)
Notes

Use only high-quality fuel.

Unleaded petrol RON 91 (95)
1) can be
used although engine output in this case is
slightly reduced.

Fuels with a higher octane number than
specified can be used without restrictions.
This does not offer any advantages in re-
spect of engine output and fuel con-
sumption, however!
1) This applies to Octavia RS and Octavia Estate
RS
Cars with a catalytic converter must only be driven with unleaded fuel.
Using fuels which contain lead results in a
lead deposit forming in the catalytic con-
verter.
Even refuelling only once with lea-
ded petrol destroys the effect of the
catalytic converter.
Even if the fuel tank is then again filled with
unleaded fuel, the original efficiency of the
catalytic converter is no longer achieved.
The operation, power output and dura-
bility of the engine are affected to a ma-
jor extent by the quality of the fuel. Do
not mix any additives into the fuel. Use
only fuel which complies with official
standards.
Diesel enginesDiesel fuel complying with DIN EN 590.
Cetane number not less than 49.
Driving in winter
Winter-grade diesel fuel
In winter a different grade of diesel fuel is
available at filling stations than during the
summer months. If „summer-grade diesel
fuel“ is used, operational problems may
occur at temperatures below 0 °C because
the diesel becomes too viscous as a result
of paraffin separation. „Winter-grade die-
sel fuel“, in contrast, is still fully operational
down to -20 °C.
In countries with different climatic condi-
tions, it is quite common to find diesel fu-
els which have a different temperature
characteristic. Škoda Dealers, and filling
stations in the particular country, will pro-
vide you with further information regarding
the diesel fuels which are available in that
country.
Biodiesel
We recommend refueling with diesel fuel
at temperatures below -10 °C.

GENERAL MAINTENANCE
Care of carRegular, professional care is a way of re-
taining the value of your car.
In addition, it may also be one of the re-
quirements for a warranty claim in the event
of possible corrosion damage and paint
defects on the body.
The care products required are available
as Original Accessories from Škoda. Al-
ways follow the instructions for use stated
on the packaging.Warning

If misused, car care products can
be harmful to health.

Car care products should always
be stored in a safe place where they
are out of the reach of children.
When buying car care products, al-
ways select products which have
been designed to minimize pollution of the environment. Do not dispose of carcare products in domestic refuse.
Fuel filter preheater
The car is equipped with a fuel filter pre-
heater. This ensures proper operation of the
fuel system down to about -25 °C when
using winter-grade diesel fuel which is re-
sistant to temperatures down to -15 °C.
Should the engine no longer start at tempe-
ratures below -25 °C, it is sufficient to park
the car for a certain time in a heated area.
Fuel additives (flow improvers) and simi-
lar products must not be added to the
diesel fuel.
Use only fuel, which complies with offi-
cial standards. Even refueling only once
with fuel which does not comply with of-
ficial standards can lead to damage in
the fuel system.
Biodiesel (PME1 fuel) conforming to
DIN EN 14 214
1)
Cetane number at least 49
Vehicles with diesel engines can also be
operated with biodiesel. The term biodiesel
specifies methyl ester from rape oil, which
must comply with the requirements of the
standard DIN EN 14 214
1).
Warning
Filling the tank even only once with
biodiesel, which deviates from the
standard DIN EN 14 2141), can lead to
damage in the fuel system. Particular features of PME fuel
Biodiesel is manufactured from vegetable
oil using a chemical process.
Biodiesel is sulphur-free which is why no
sulphur dioxide (SO
2) is released when it
is combusted.
The exhaust gas contains less
- carbon monoxide (CO)
- hydrocarbons (HC)
- particulates (e.g. soot)
than when the engine is operated with a
conventional diesel fuel.
If biodiesel is used, the vehicle performance
may be slightly lower and, on the other hand,
fuel consumption may be slightly higher.
Biodiesel is biologically degradable.
PME fuel according to DIN EN 14 214
1) can
be mixed in any desired ratio with diesel
fuel conforming to DIN EN 590.
Driving in winter
PME fuel is suitable for use in winter only
down to -10 °C.
Fuel additives (flow improvers) and simi-
lar products must not be added to the
biodiesel fuel.
