WARNING
Even with this function the vehicle ca
nnot steer itself! The
driver is further-
more responsible for the steering of the vehicle!BrakesWhat has a negative effect on braking efficiency?Wear-and-tear Wear-and-tear to the brake pads is greatly dependent on the operating conditions of the vehicle and your style of driving. Particularly if you drive a great deal in towns and over short distances or if you adopt a
sporty style of driving, it may be neces-
sary to have the thickness of the brake
pads inspected at a specialist garage
between the service inspections. Wet roads or road salt There may be a certain delay before the br
akes take full effect under certain condi-
tions such as when driving through water,
during heavy rain
showers or after the
vehicle has been washed in
an automatic vehicle wash, since the brake discs and
brake pads may be moist or even have a
coating of ice on them in winter. You
should dry the brakes as soon as possib
le by applying and releasing the brakes
several times. There also may be a certain delay before the
full braking efficiency is available when
driving on roads which have been treated wi
th road salt if yo
u have not used the
brakes for some considerable time beforeha
nd. The layer of salt on the brake discs
and brake pads must first be rubb
ed off when you apply the brakes.
Corrosion Corrosion on the brake discs and dirt on th
e bake pads occur if
the vehicle has been
parked for a long period and if you do
not make much use of the braking system.
We recommend cleaning the brake discs by
firmly applying the brakes at a fairly
high speed if you do not make much use of the braking system or if surface corro- sion is present
⇒
.
Faults in the brake surface If you notice that the braking distance
has suddenly become longer and that the
brake pedal can be depressed further, it is
possible that a brake circuit of the dual-
circuit brake system has failed. Drive, in such cases, to the nearest specialist garage without delay in order to have the problem rectified. Drive at a reduced speed while on your way to the dealer and adapt your style of driving to the higher brake pedal pressure required. Low brake fluid level An insufficient level of brake fluid may result in problems in the brake system. The level of the brake fluid is monitored electronically
⇒page 40, “Brake system
”.
WARNING
•
Only apply the brakes for the purpos
e of drying and cleaning the brake
discs if the traffic conditions permit this. Do not place any other road users in jeopardy.•
When retrospectively mounting a front
spoiler, solid wheel hubs etc. one
must ensure that the air supply to the front wheel brakes is not reduced otherwise the braking sy
stem could run too hot.
•
Allow for the fact that new brake pads
do not achieve th
eir full braking
efficiency until approximately 200 kilo
metres. New brake pads must be first
“run in” before they develop their optimal friction force. You can, however, compensate for this slightly reduced
braking force by increasing the pres-
sure on the brake pedal. This guidelin
e also applies to any new brake pads
installed at a future date.
Caution
•
Never allow the brakes to ru
b by applying slig
ht pressure if you do not wish to
brake the vehicle. This causes the brakes to overheat and can also result in a longer braking distance and excessive wear.•
Before negotiating a steep downhill sect
ion, please reduce your speed, shift
down into the next lower gear (manual ge
arbox) or select a lower driving stage
(automatic gearbox). This enables you to make full use of the braking power of the

WheelsSteel wheels You should also thoroughly wash the wheels and wheel trims when giving your vehicle its regular wash. This prevents an
y 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 part
icularly important to remove regularly any
road salt and brake abrasion from light alloy wheels, otherwise the light metal will suffer. Wash thoroughly and then treat the wheels with a protective product for light alloy wheels which does not contain an
y acidic components. We recommend to
apply a hard wax layer onto the wheel hub
s 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 th
e 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 protectionThe 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. The authorised Škoda Service Partners have suitable
spray products
available as
well as the necessary 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 an authorised 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 spacesAll 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!

Raise vehicle You have to raise the vehicle with the lifting jack* in order to be able to take off the wheel.Position the lifting jack* by selecting the jacking point which is closest to the wheel to be removed
⇒
fig. 228
. The jacking point is located directly
below the engraving in the lower sill. The engraving is only visible after opening the door. – Position the lifting jack* below the jacking point and move it up until
its claw is positioned di
rectly below the vertical web of the lower sill.
– Align the lifting jack* so that its claw grasps the web of the lower sill
and the base plate is resting flat on the floor.
– Turn the lifting jack* up further until the wheel is just clear of the
ground.
Ground which is soft and slippery
below the lifting jack* can cause the vehicle to
slip off the lifting jack*. It is therefore al
ways necessary to place the lifting jack* on
a solid surface or use a wide and stable ba
se. Use a non-slip base (e.g. a rubber foot
mat) if the
surface is smooth
, such as cobbled stones, a tiled floor, etc.
WARNING
•
Always raise the vehicle with the doors closed - risk of injury!
•
Take suitable measures to prevent the
base of the lifting jack from slip-
ping off - risk of injury!•
Not positioning the lifting jack* at
the specified points can result in
damage to the vehicle. The lifting jack* ca
n also slip off if it does not have
sufficient grip - risk of injury!•
It is important to support the vehicle with suitable supporting blocks if
you wish to work under the lifted vehicle - risk of injury!Securing wheels against being stolen* You need a special adapter for slackening the safety wheel bolts.– Pull off the full wheel trim/cap from the wheel hub or cap from the
safety wheel bolt.
– Insert the adapter with its toothed side fully into the inner toothing
of the safety wheel bolt right down in such a way that only the outer hexagon is jutting out
⇒

.
– Insert the wheel wrench* fully onto the adapter . – Slacken the wheel bolt, or tighten it firmly
