1 Contact corrosion
(SRL000764; Edition 12.2014)
The use of unsuitable connection elements (screws, nuts, wash‐
ers, …) causes contact corrosion.
This is why only connection elements with a special surface coat‐
ings are fitted.
Therefore, the rubber or plastic parts and the adhesives are made
from electrically non-conductive materials.
In case of doubt regarding the re-use of certain parts, the use of
new parts is recommended.
WARNING
♦ It is recommended to use only original connection material
as well as spare parts which are tested and compatible
with aluminium, see ⇒ Electronic Catalogue of Original
Parts .
♦ It is recommended to use only Škoda accessories.
♦ Any damage resulting from contact corrosion is not cov‐
ered by the terms of the warranty.
Note
♦ It is possible to use the contact surface cleaning set -
VAS6410- for repair work on contact surfaces which show
traces of contact corrosion (oxidation).
♦ Examples for application of the contact surface cleaning set -
VAS6410- can be found in the Workshop Manual “Electrical
System – General notes” ⇒ Electrical System – General notes;

WARNING
When working on the battery, wear proper protection and ob‐
serve safety precautions (see “Electrical System – General
notes” ⇒ Electrical System – General notes; Rep. gr. 27 ).

2.1 Basics, battery types
Batteries with a magic eye and plugs covered in adhesive tape
are factory-installed in all vehicles (except vehicles with start-stop
system).
In vehicles with start/stop system, (depending on types of engines
see ⇒ Electronic Catalogue of Original Parts ) a fleece battery
(AGM) or a battery with magic eye with EFB technology (En‐
hanced Flooded Battery) is mounted.
The AGM battery is also mounted in vehicles with auxiliary heat‐
ing and additional heating.
Description of the function, test and maintenance of the previous
batteries see “Electrical System – General notes” ⇒ Electrical
System – General notes; Rep. gr. 27 .
2.2 Warning instructions and safety precau‐
tions when working on the battery

2.3.1 Disconnecting battery
– Switch off all electrical components and ignition, take out the
ignition key.
– Open the cover of the heat protection sleeve.

– Open cover -1-, loosen nut -3- and disconnect battery earth
strap -2- only.
Note
If both terminals are disconnected, only then disconnect pole ter‐
minal (-) from battery earth.
2.3.2 Work sequence when connecting the
battery
WARNING
Observe the following additional instructions after working on
the airbag system or on the electric belt tighteners or the safety
belts:
♦ Switch on the ignition before connecting the battery.
♦ Nobody should be in the vehicle when the battery is being
connected.
♦ If the vehicle is equipped with the interface for entry and
start system (Kessy), the ignition should only be switched
on after connecting the battery using the ⇒ Vehicle diag‐
nostic tester outside the vehicle cockpit (the valid ignition
key must be inside the vehicle) for safety reasons. This
procedure is part of the tests in the targeted fault finding.
Note
♦ Neither grease nor oil the battery terminals.
♦ The battery pole terminals must only be fitted by hand without
using any force in order to avoid damaging the battery hous‐
ing.
♦ Install the battery pole terminals in such a way that the battery
poles are flush with the terminals or protrude.
♦ If both terminals are disconnected, only then disconnect the
battery positive pole terminal (+).
♦ The tightening torque is the same for all shapes of pole termi‐
nals (6 Nm).
♦ After connecting the battery and switching on the ignition, the
warning light for the stability programme TCS/ESC and the
warning light for the power-assisted steering remain lit. The
warning lights go out automatically after driving a few metres
forward. Thereby the steering angle sender - G85- is activated
again.
– Switch off all electrical components and take out the ignition
key.

trol unit - J367- when replacing the battery with a new one of
another type or with higher capacity.
After a new start battery is installed and the battery has been par‐
ameterised, the technical data of the new battery are sent to the
battery monitoring control unit - J367- .
– ⇒ Vehicle diagnostic tester connect and select the operating
mode “Targeted fault-finding”.
– Select the “Selected Functions/Components” and subse‐
quently the following menu points using the button “Skip”:
♦ Body
♦ Electrical system
♦ Diagnostic capable systems
♦ Checking battery
♦ Battery monitoring function

Installing
Installation is carried out in the reverse order. When installing,
observe the following:
Caution
The line to terminal B+ must be laid and attached so that it does
not come into contact with rotating or moving parts of the as‐
sembly (e.g. with the shift mechanism, with rotating parts of the
assembly etc.)!
If the line is laid/attached incorrectly to terminal B+, there is a
risk of damage to the line and of a short circuit or fire.
Note
Use new self-locking nuts -1- and -3- for attaching the earth strap
and the positive cable, see ⇒ Electronic Catalogue of Original
Parts .

Installing
Installation is carried out in the reverse order. When installing,
observe the following:
Caution
Follow the mounting sequence for the V-ribbed belt ⇒ Engine;
Rep. gr. 13
Fix the B+ wire correctly to the AC generator
⇒ “4.3 Fixing the B+ wire to the AC generator”, page 12 .
– Vehicles with AC generator secured from the front side – for
easier mounting move the threaded bushes -A- approx. 3 mm
-arrows-.
– Observe the tightening torque for fastening the B+ wire see
⇒ “4.3 Fixing the B+ wire to the AC generator”, page 12 .
– Pay attention to the work sequence when connecting the bat‐
tery
⇒ “2.3 Work sequence when disconnecting and connecting
the battery”, page 2 .
– After work has been carried out, always start the engine and
check that the belt is running correctly.
4.3 Fixing the B+ wire to the AC generator
Caution
The screw connection for the B+ cable at the generator is iden‐
tified with B1+!
If the B+ cable is not tightened to the specified tightening tor‐
que, this may result in the following risks:
♦ The battery will not charge fully.
♦ Complete failure of vehicle electronics
♦ Spark formation may cause a fire
♦ Damage resulting from overvoltage on electronic compo‐
nents and control units
The line to terminal B+ must be laid and attached so that it does
not come into contact with rotating or moving parts of the as‐
sembly (e.g. with the shift mechanism, with rotating parts of the
assembly etc.)!
If the line is laid/attached incorrectly to terminal B+, there is a
risk of damage to the line and of a short circuit or fire.
