2007 SKODA OCTAVIA warning light

Intelligent Technology

The majority of drivers do apply the brakes in good time in dangerous situations,
but do not depress the brake pedal with su fficient pressure. Consequently, it is not
possible for the car to achieve its maximum deceleration and the car covers a
greater distance than necessary.
The Brake Assist is activated by the very quick operation of the brake pedal. In such
cases, a much greater braking pressure ex ists than during a normal brake applica-
tion. This makes it possible, even with a relatively low resistance of the brake pedal,
to produce an adequate pressure in the brake system in the shortest possible time,
which is required for maximum deceleration of the car. You must apply the brake
pedal firmly and hold it in this position in order to achieve the shortest possible
braking distance.
The Brake Assist is able to help you achieve a shorter braking distance in emergency
situations by rapidly producing the pressure required in the brake system. It fully
exploits the attributes of the ABS. After you release the brake pedal, the function of
the Brake Assist is automatically switched off and the brakes operate in the normal
way.
The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake Assist
function is also not available. Further information on the ESP ⇒page 181.
WARNING
•The Brake Assist is also not able to overcome the physical limits of your
car in terms of the braking distance required.
•Adapt your speed to the conditions of the road surface and to the traffic
situation.
•The increased safety offered by the Brake Assist must not tempt you to
take a greater safety risk than otherwise.
Uphill-Start off-Assist*
The uphill-start off-assist makes it much easier to start off on steep hills. The system
assists a start off by holding the brake pr essure produced by the brake pedal actu-
ation for approx. 2 seconds after releasing the brake pedal. The driver can therefore
move his foot from the brake pedal to the accelerator pedal and start off on the slope, without having to actuate the hand
brake. The brake pressure drops gradually
the more you operate the accelerator pedal. If the vehicle does not start off within
2 seconds, it starts to roll back.
The uphill-start off-assist is active in the ev ent of a 5% slope, if the vehicle door is
closed. It is alwa ys active on slopes when in forward or reverse start off. When
driving downhill, it is inactive.
Electromechanical power steering
The power steering enables you to steer the vehicle with less physical force.
With the electromechanical power steering, the steering assist is automatically
adapted to the speed and to the steering angle.
It is still possible to fully steer the vehicle if the power steering fails or if the engine
is not running (vehicle being towed in). The only difference is that greater physical
effort is required.
If there is a fault in the power steering, a red or yellow warning light
 lights up in
the instrument cluster ⇒page 27.
WARNING
Contact your specialist garage if the power steering is defective.

Tyre inflation pressure-control system*
The tyre inflation pressure-control system compares with the aid of the ABS sensors
the speed and also the rolling circumference of the individual wheels. If the rolling
circumference of a wheel is changed, the warning light
 lights up in the dash
panel insert ⇒page 30. The rolling circumference of the tyre can change if:
•the tyre inflation pressure is too low,
•the structure of the tyre is damaged,
•the vehicle is loaded on one side,
•the wheels of an axle are loaded heavily (e.g. when towing a trailer or when
driving uphill or downhill),
•snow chains are mounted,
•the temporary spare wheel is mounted,
•one wheel per axle was changed.
Basic setting of tyre inflation pressure-control system
After changing the tyre inflation pressures or after changing one or several wheels,
a basic setting of the system must be carried out as follows.
•Inflate all tyres to the specified inflation pressure ⇒page 223.
•Switch on the ignition.
•Press button   ⇒ fig. 186 for more than 2 second s. While pressing the
button, the warning light  lights up. At the same time the basic values are stored,
which is confirmed with an acoustic sound and then the warning light  goes out.
•If the warning light  does not go out after the basic setting, there is a fault in
the system. Have the vehicle inspected by your nearest specialist garage.
Warning light
 lights up
If the tyre inflation pressure of at least on e wheel is insufficiently inflated in compar-
ison to the stored basic value, the warning light
 ⇒ lights up.
Warning light
 flashes
If the warning light flashes, there is a system fault. Have the vehicle inspected by
your nearest specialist garage.
WARNING
•When the warning light  lights up, immediately reduce the speed and
avoid sudden steering and brake mano euvres. Please stop the vehicle
without delay at the nearest possible stop and inspect the tyres and their
inflation pressures.
•The driver is responsible for the correc t tyre inflation pressures. For this
reason, the tyre inflation pressures must be checked regularly.
•Under certain circumstances (e.g. sporty style of driving, wintry or
unpaved roads) the warning light  can be delayed or does not light up at
all.
•The tyre inflation pressure-control system does not take away the
responsability from the driver for the correct tyre inflation pressure.
Note
The tyre inflation pressure-control system:
•does not replace the regular tyre inflatio n pressure control, because the system
cannot detect an even pressure loss,
•cannot warn in case of very rapid tyre inflation pressure loss, e.g. in case of
sudden tyre damage. In this case carefully bring the vehicle to a standstill without
sudden steering movements and without sharp braking.

Diesel particle filter* (diesel engine)
In the diesel particle filter the resulting soot particles are collected
and burnt during the combustion of diesel fuel.
Code 7GG on the vehicle data sticker ⇒fig. 187 indicates that your
vehicle is equipped with a diesel particle filter. The vehicle data sticker is
located on the floor of the luggage compartment and is also stated in the
Service schedule.
The diesel particle filter filters the soot particles completely from the exhaust. The
soot is collected in the diesel particle filter and burnt regularly. To assist this proce-
dure, we recommend not to drive regularly over short distances.
If the diesel particle filter is clogged or there is a fault, it is indicated by the warning
light
 ⇒ page 26, “Diesel particle filter*  (diesel engine)”.
WARNING
•The diesel particle filter achieves very high temperatures. Therefore do
not park at points where the hot filter comes into direct contact with dry
grass or other combustible materials - risk of fire!
•Never use additional underbody protection or corrosion-protection
agents for the exhaust pipes, catalytic converters, diesel particle filter or
heat shields. When the engine reaches its operating temperature, these
substances might ignite - risk of fire.
Note
•When using diesel fuel with high sulphur content the life of the diesel particle
filter is clearly reduced. A specialist garage will be able to tell you which countries
use only diesel fuel wi th high sulphur content.

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 55.
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 198.
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 temperature 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, particularly 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 11.
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 215, “Inspecting the coolant level”.
Please refer to the following guidelines ⇒page 28, “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

of the engine speed. One should also not drop a gear for this reason when towing
a trailer as long as the en gine can manage the slope without any drop in speed.
Detachable towing device*
The detachable ball head of the towing device is stowed in a box for the car tool kit
in the spare wheel well in the luggage compartment.
An instruction for correct installation an d removal of the ball head of the towing
device is supplied with the ball head
Inspect the ball head to ensure that it is properly locked each time before setting off.
The inspection is performed by turning the closed locking lever downwards. If the
locking lever can only be turned around a small angle (approx. 5°), the locking
mechanism is O.K. 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 closed position.
WARNING
Do not use any aids or tools for installing or removing the ball head. This
might result in damage to the locking mechanism to the extent that the
safety of the towing device is no longer assured - risk of an accident.
Note
•Do not carry out any modifications or repairs to the ball head or to any other
components on the towing device.
•Contact a specialist garage if you en counter any problems using the device.
•Never unlock the ball head with a trailer coupled to it.
•You should take off the ball head if you drive without towing a trailer. Inspect
whether the end cover properly seals off the mounting shaft.
•Remove the ball head beforehand if yo u wish to clean your vehicle using a
steam jet. Ensure that the end cover properly seals the mounting shaft.
•It is recommended to wear gloves when installing and removing.

Automatic vehicle wash systems
The paintwork of the vehicle is sufficiently resistant that the vehicle can be washed
normally in automatic vehicle wash plants without any problem. The actual stress
to which the paintwork is subjected, however, depends greatly on the design of the
vehicle wash system, the filtering of the water and the type of washing and care
products used. If the paintwork of your vehicle appears mat after being washed or
even has scratches, point this out to the operator of the vehicle wash plant. Use a
different vehicle wash plant, if necessary.
There are no particular points to note be fore washing your vehicle in such a plant
other than the usual precautionary measur es (closing windows and sliding/tilting
roof, moving any factory-fitted aerials down flat against the bodywork, etc.).
If you have any particular atta ch e d p a r t s f i t te d t o y o u r c a r - s u ch a s s p o i l e r, ro o f ra ck
system, two-way radio aerial - it is best to first of all consult the operator of the car
wash plant.
It is important to degrease the lips of the windscreen wiper rubbers after passing
through the automatic vehicle wash system.
Caution
Do not screw the swivelling down roof aeri al tight before washing the vehicle in an
automatic vehicle wash sy stem - risk of damage!
Washing vehicle by hand
It is important to first soften the dirt with plenty of water and rinse it off as thor-
oughly as possible before wa shing your vehicle by hand.
One should then clean the vehicle using a soft washing sponge, washing glove or
a washing brush and only slight pressure. Work from the top to the bottom -
beginning with the roof. Only place slight pressure on the vehicle paintwork during
cleaning Only use a car shampoo for stubborn dirt.
Wash out the sponge or washing glove thoroughly at short intervals.
Clean wheels, door sills and similar parts last. Use a second sponge for such areas. Rinse off the vehicle well after giving it a wash and dry it off using a chamois leather.
WARNING
•The ignition should always be switched off when you wash your vehicle -
risk of accident!
•Protect your hands and arms from sharp-edged metal parts when you
are cleaning the underfloor, the inside of the wheel housings or the wheel
trims - risk of cuts.
Caution
•Do not wash your vehicle in bright sunlight - risk of paint damage.
•Ensure that the jet of water is not aimed directly at the locks or at the door and
panel joints if you spray your vehicle in winter down with a hose - risk of freezing.
•Do not use any insect sponges, rough ki tchen sponges or similar cleaning prod-
ucts - risk of damage to the surface of paintwork.
For the sake of the environment
Only wash your vehicle at washing bays specifically reserved for this purpose. This
ensures that no water which may be cont aminated by oil flows into the sewage
system. It is not even permitted to wash your vehicle in certain areas except at such
specific washing bays.
Washing with a high-pressure cleaner
When you wash your vehicle with a high-pressure cleaner, it is essential to comply
with the instructions for use of the cleaning equipment. This applies in particular to
the pressure used and to the spraying distance . Maintain a sufficiently large
distance to soft materials such as rubber hoses or insulation material.
On no account use circular spray nozzles or so-called dirt cutters!

WARNING
It is particularly important that you do not clean tyres with circular spray
jets. Visible but also invisible damage to tyres may occur even at a relatively
large spraying distance and if sprayed only for a short time - risk of accident!
Caution
The water containing wax must be no hott er than 60°C, otherwise the vehicle can
be damaged.
Wax treatment
Good wax treatment is an effective way of protecting the paintwork from harmful
environmental influences an d minor mechanical damage.
The vehicle must be treated with a high-qua lity hard wax polish at the latest, when
no more drops form on the clean paintwork.
A new layer of a high-quality hard wax polish can be applied to the clean bodywork
after it has dried thoroughly. Even if you use a wax preserver regularly we still
recommend that you treat the paintwork of the vehicle at least twice a year with
hard wax.
Caution
Never apply wax to the windows.
Polishing
Polishing is only necessary if the paintwor k of your vehicle has become unattractive
and if it is no longer possible to achieve a gloss with wax preservers.
You must treat the paintwork with a wax preserver if the polish you use does not
contain any preserving elements ⇒page 201, “Wax treatment”.
We recommend using a preservative from Škoda genuine accessories offered by
your Škoda dealer.
Caution
•You must not treat mat painted parts or plastic with polishing products or hard
wax.
•Do not polish the paintwork of the vehicle in a dusty environment, otherwise
the paintwork can be scratched.
Chrome parts
First clean the chrome parts with a damp clotch and then polish them with a soft,
dry cloth. If it does not prove to be adequate, use a chrome care product from
Škoda original accessories.
Caution
Do not polish the chrome parts in a du sty environment, otherwise they can be
scratched.
Paint damage
Slight damage to paintwork such as scratche s, scuffs or traces of chip damage must
be touched up immediately with paint (Škoda painting pen) before any corrosion
can result. You can of course have this wo rk carried out by a Škoda Service Partner.
Škoda Service Partners have a range of matching touch-up pens or spray cans
available in the colo ur of your vehicle.
The paint number of the original paintwor k of your vehicle is indicated on the
vehicle data sticker ⇒page 255.
Any corrosion which has already have formed must be removed thoroughly. Apply
a corrosion protection primer and then the paint to the affected point. You can of
course have this work carried out by a Škoda Service Partner.

Wheels
Steel wheels
You should also thoroughly wash the wheels and wheel trims when giving your
vehicle its regular wash. This prevents any brake dust, dirt and road salt from
sticking to the wheel hubs. You can remove stubborn brake abrasion adhering to
t h e w h e e l s w i t h a n i n d u s tr i a l c l e a n e r. To u c h u p a n y d a m a g e to t h e p a i n tw o r k o n th e
wheels before rust is able to form.
Light alloy wheels
Regular care of light alloy wheels is necessary in order to retain their decorative
appearance over long periods. It is partic ularly important to remove any road salt
and brake abrasion from light alloy wheels every two weeks, otherwise the surface
will suffer. Wash thoroughly and then treat the wheels with a protective product for
light alloy wheels which does not contain any acidic components. You should
provide the wheel hubs with a hard wax la yer every three months. You must not use
any products which cause abrasion when treating the wheel hubs. Any damage to
the paint layer on the wheel hubs must be touched up immediately.
We recommend using a preservative from Škoda genuine accessories offered by
your Škoda dealer.
WARNING
One should remember when cleaning th e wheels that moisture, ice and road
salt may adversely affect braking ef ficiency - risk of an accident!
Note
Severe layers of dirt on the wheels can also result in wheel imbalance. This may
show itself in the form of a wheel vibration which is transmitted to the steering
wheel which, in certain circumstances, ca n cause premature wear of the steering.
This means it is necessary to remove the dirt.
Underbody protection
The underside of your vehicl e is protected for life against chemical and mechanical
influences.
One cannot, however, completely rule out damage to the protective layer when
driving so we recommend that you inspect the protective layer on the underside of
your vehicle and on the chassis at certain in tervals - this is best done at the begin-
ning and end of the winter - and to touch up any damaged areas.
Škoda Service Partners have suitable spray products available as well as the neces-
sary equipment and are familiar with the instructions for use. It is therefore best to
have such touch-up work or additional corrosion protection measures carried out
by a Škoda Service Partner.
WARNING
Never use additional underbody protection or corrosion-protection agents
for the exhaust pipes, catalytic converte rs, diesel particle filter or heat
shields. When the engine reaches its operating temperature, these
substances might ignite - risk of fire!
Protection of hollow spaces
All the cavities of your vehicle which are at risk from corrosion are protected for life
by a layer of protective wax applied in the factory.
This wax protection does not require to be inspected or re-treated. Please remove
any small amount of wax which flows out of the cavities at high temperatures with
a plastic scraper and clean the spot using petroleum cleaner.
WARNING
Safety and environmental protection regulations should observed when
using petroleum cleaner to re move wax - a risk of fire!
