The essentials
If for weather reasons further protection is
nec e
s
sary, the proportion of additive may be
increased, but only up to 60 %; otherwise an-
tifreeze protection will diminish and this will
worsen cooling.
When the coolant is topped up, use a mixture
of distilled water and at least 40 % of the
G13 or G12 plus-plus (TL-VW 774 G) additive
(both are purple) to obtain an optimum anti-
corrosion protection ››› in Topping up cool-
ant on p ag
e 280

. The mixture of G13 with
G12 plus (TL-VW 774 F), G12 (red) or G11
(green-blue) engine coolants will significant-
ly reduce anti-corrosion protection and
should therefore be avoided ››› in Topping

al contact with the battery termi-
nals.
If the engine fails to start after about 10 sec-
onds, switch off the starter and try again after
about 1 minute. WARNING
● Ple a

se note the safety warnings referring to
working in the engine compartment
›››  page 273, Working in the engine
compartment.
● The battery providing assistance must have
the same v
oltage as the flat battery (12 V)
and approximately the same capacity (see
imprint on battery). Failure to comply could
result in an explosion.
● Never use jump leads when one of the bat-
teries
is frozen. Danger of explosion! Even af-
ter the battery has thawed, battery acid could
leak and cause chemical burns. If a battery
freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes
awa
y from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufact
urer of the jump leads.
● Do not connect the negative cable from the
other vehic
le directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion. ●
Never att ac

h the negative cable to fuel sys-
tem components or the brake lines in the oth-
er vehicle.
● The non-insulated parts of the battery
clamp
s must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot c
ome into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult
in chemical burns. Note
The vehicles must not touch each other, oth-
erw i

se electricity could flow as soon as the

Airbag system
in your vehicle. Because the airbag deploys
from the s
ide of
the backrest, the use of con-
ventional seat covers would obstruct the side
airbag, seriously reducing the airbag's effec-
tiveness.
● Any damage to the original seat upholstery
or around the se
ams of the side airbag units
must be repaired immediately by a special-
ised workshop.
● The airbags provide protection for just one
accident; r
eplace them once they have de-
ployed.
● Any work on the side airbag system or re-
mova
l and installation of the airbag compo-
nents for other repairs (such as removal of
the front seat) should only be performed by a
specialised workshop. Otherwise, faults may
occur during the airbag system operation.
● Do not attempt to modify components of
the airbag sys
tem in any way.
● The side and head airbags are managed
through sensor
s located in the interior of the
front doors. To ensure the correct operation of
the side and curtain (head) airbags neither
the doors nor the door panels should be
modified in any way (e.g. fitting loudspeak-
ers). If the front door is damaged, the airbag
system may not work correctly. All work car-
ried out on the front door must be done in a
specialised workshop.
● In a side-on collision the side airbags will
not work
if the sensors do not correctly meas-
ure the pressure increase on the interior of
the doors, due to air escaping through the areas with holes or openings in the door pan-
el.
● Nev er driv

e if the interior door panels have
been remov
ed or if the panels have not been
correctly fitted.
● Never drive the vehicle if the loudspeakers
in the door panels
have been removed, un-
less the holes left by the loudspeakers have
been closed properly.
● Always check that the openings are closed
or cov
ered if additional loudspeakers or other
equipment are fitted inside the door panels.
● Any work carried out to the doors should be
made in an authori
sed specialised workshop. Head-protection airbags*

 page 23. WARNING
● In order f or the he

ad-protection airbags to
provide their maximum protection, the pre-
scribed sitting position must always be main-
tained with seat belts fastened while travel-
ling.
● For safety reasons, the curtain airbag must
be disab
led in those vehicles fitted with a
screen dividing the interior of the vehicle.
See your technical service to make this ad-
justment. ●
There mu s

t be no other persons, animals or
objects between the occupants of the outer
seats and the deployment space of the head-
protection airbags so that the head-protec-
tion airbag can deploy completely without re-
striction and provide the greatest possible
protection. Therefore, sun blinds which have
not been expressly approved for use in your
vehicle may not be attached to the side win-
dows
● The built-in coat hooks should be used only
for lightweight
clothing. Do not leave any
heavy or sharp-edged objects in the pockets.
Please, do not hang the clothes on coat hang-
ers.
● The airbags provide protection for just one
accident; r
eplace them once they have de-
ployed.
● Any work on the head-protection airbag
syst
em or removal and installation of the air-
bag components for other repairs (such as re-
moval of the roof lining) should only be per-
formed by a specialised workshop. Other-
wise, faults may occur during the airbag sys-
tem operation.
● Do not attempt to modify components of
the airbag sys
tem in any way.
● The side and head airbags are managed
through sensor
s located in the interior of the
front doors. To ensure the correct operation of
the side and curtain airbags neither the
doors nor the door panels should be modified
in any way (e.g. fitting loudspeakers). If the
front door is damaged, the airbag system
may not work correctly. All work carried out » 89

Transporting children safely
●
Never in s
tall a child seat facing backwards
on the front passenger seat unless the front
passenger front airbag has been disabled.
Risk of potentially fatal injuries to the child!
However, if it is necessary, in exceptional ca-
ses, to transport a child in the front passen-
ger seat, the front passenger front airbag
must always be disabled ››› page 90, Activa-
tion and deactivation of front passenger air-
bag*. If the passenger seat has a height ad-
justment option, move it to the highest, most
upright position. If it is a fixed seat, it should
be moved to the rearmost position possible.
● For those vehicles that do not include a key
lock sw
itch to deactivate the airbag, the vehi-
cle must be taken to a technical service. Do
not forget to reconnect the airbag when an
adult wants to sit in the front passenger seat.
● All vehicle occupants, especially children,
must
assume the proper sitting position and
be properly belted in while travelling.
● Never hold children or babies on your lap,
this c
an result in potentially fatal injuries to
the child!
● Never allow a child to be transported in a
vehicl
e without being properly secured, or to
stand up or kneel on a seat while travelling.
In an accident, the child could be flung
through the vehicle, causing possibly fatal in-
juries to themselves and to the other vehicle
occupants.
● If children assume an improper sitting posi-
tion when the vehic
le is moving, they expose
themselves to greater risk of injury in the
event of a sudden braking manoeuvre or in an accident. This is particularly important if the
chi
l

d is travelling on the front passenger seat
and the airbag system is triggered in an acci-
dent; as this could cause serious injury or
even death.
● A suitable child seat can protect your child!
● Never leave a child alone in the child seat
or inside the
vehicle because depending on
the season, very high temperatures may be
reached inside a parked vehicle, which could
be fatal.
● Children who are less than 1.5 metres tall
must
not wear a normal seat belt without a
child seat, as this could cause injuries to the
abdominal and neck areas during a sudden
braking manoeuvre or in an accident.
● Do not allow the seat belt to become twis-
ted and the seat
belt should be properly in
place ››› page 81.
● Only one child may occupy a child seat
›››

page 93, Child seats.
● When a child seat is mounted in the rear
seats, the door c
hild-proof lock should be ac-
tivated ››› page 138. Child seats

rings - this can result in potentially fatal inju-
ries to the child.
● Ensure that the child seat is secured cor-
rectly u
sing the “ISOFIX” and Top Tether* se-
curing rings. WARNING
An undue installation of the safety seat will
incr e

ase the risk of injury in the event of a
crash.
● Never tie the retainer strap to a hook in the

Perfect windscreen wiper blade condition is
essential for clear vision. Damaged wiper
blades should be replaced immediately.
The windscreen wiper blades are supplied as
standard with a layer of graphite. This layer is
responsible for ensuring that the wipe is si-
lent. If the graphite layer is damaged, the
noise of the water as it is wiped across the
windscreen will be louder.
Check the condition of the wiper blades regu-
larly. If the wipers scrape across the glass ,
they should be changed if they are damaged,
or cleaned if they are dirty ››› .
If thi
s

does not produce the desired results,
the setting angle of the windscreen wiper
arms might be incorrect. They should be
checked by a specialised workshop and cor-
rected if necessary. WARNING
Do not drive unless you have good visibility
through a l

l windows! ●
Cle

an the windscreen wiper blades and all
windows regularly.
● The wiper blades should be changed once
or twice a
year. CAUTION
● Dam aged or dir

ty windscreen wipers could
scratch the glass.
● Never use fuel, nail varnish remover, paint
thinner or simil
ar products to clean the win-
dows. This could damage the windscreen
wiper blades.
● Never move any windscreen wiper by hand.
This c
ould cause damage.
● To prevent damage to the bonnet and the
winds
creen wiper arms, the latter should only
be lifted off the windscreen when in service
position. Note
● The wind s

creen wiper arms can be moved
to the service position only when the bonnet
is properly closed.
● You can also use the service position, for
examp
le, if you want to fix a cover over the
windscreen in the winter to keep it clear of
ice. Towing or tow-starting

Tow-starting means starting the engine of
the vehicle while another pulls it.
Towing means one vehicle pulling another
that is not roadworthy.
If the vehicle comes with the Keyless Access
system, towing is only allowed with the igni-
tion on!
The vehicle battery drains if the vehicle is
towed with the engine switched off and the
ignition connected. Depending on the battery
charge status, the drop in voltage may be so
large, even after just a few minutes, that no
electrical device in the vehicle may work e.g.
the hazard warning lights. In vehicles with
the Keyless Access system, the steering
wheel could lock up. WARNING
If the vehicle has no electrical power, the
brak e light

s, turn signals and all other lights
will no longer function. Do not have the vehi-
cle towed away. Failure to follow this instruc-
tion could result in an accident. 100
