It is also important for rear passengers to
wear seat belts properly, as they could other-
wise be thrown forward violently through the
vehicle interior in an accident. Passengers in
the rear seats who do not use seat belts en-

the seat belt is not positioned correctly.
● Adjust the seat and head restraint correctly.
● To fasten the belt, take hold of the latch
plat
e and pull it slowly across your chest and
lap.
● Insert the latch plate into the buckle for the
appropri
ate seat and push it down until it is
securely locked with an audible click

Safety
The seat belts are equipped with an automat-
ic r
etr
actor on the shoulder strap. Full free-
dom of movement is permitted when the
shoulder belt is pulled slowly. However, dur-
ing sudden braking, during travel in steep
areas or bends and during acceleration, the
automatic retractor on the shoulder belt is
locked.
The automatic belt retractors on the front
seats are fitted with seat belt tensioners

Releasing the seat belt ● Press the red button on the belt buckle
›››
Fig. 93 B. The latch plate is released and
springs out ››› .
● Guide the belt back by hand so that it rolls
up e a
s

ily and the trim is not damaged.
Positioning seat belts
Seat belts offer their maximum protection on-
ly when they are properly positioned. WARNING
● The seat belt

s offer best protection only
when the backrests are in an upright position
and the seat belts have been fastened prop-
erly.
● Never put the latch plate in the buckle of
another seat. If
you do this, the seat belt will
not protect you properly and the risk of injury
is increased. ●
Never u nb

uckle a seat belt while the vehi-
cle is in motion. If you do, you increase the
risk of sustaining severe or fatal injuries.
● An incorrectly worn seat belt can cause se-
vere injurie
s in the event of an accident.
● For pregnant women, the lap part of the
seat belt
must lie as low as possible over the
pelvis, never across the stomach, and always
lie flat so that no pressure is exerted on the
abdomen ››› Fig. 94.
● Always engage the retractor lock when you
are securin

The seat belts for the occupants in the front
seats are equipped with belt tensioners. Sen-
sors will trigger the belt tensioners only dur-
ing severe head-on, lateral and rear-end colli-
sions and only if the seat belt is worn. This
retracts and tightens the seat belts, reducing
the forward motion of the occupants.
The belt tensioners will not be triggered in
the event of minor collisions, if the vehicle overturns, or in accidents where no major
forc

es act on the vehicle. Note
● If the se at

belt tensioners are triggered, a
fine dust is produced. This is normal and it is
not an indication of fire in the vehicle.
● The relevant safety requirements must be
obser
ved when the vehicle or components of
the system are scrapped. Specialised work-
shops are familiar with these regulations,
which are also available to you. Maintenance and disposal of belt ten-

ioner
s The belt tensioners are components of the
se
at
belts

that are installed in the seats of
your vehicle. If you work on the belt tension-
ers or remove and install parts of the system
when performing other repair work, the seat
belt may be damaged. The consequence may
be that, in the event of an accident, the belt
tensioners function incorrectly or may not
function at all.
So that the effectiveness of the seat belt ten-
sioner is not reduced and that removed parts
do not cause any injuries or environmental
pollution, regulations, which are known to
the specialised workshops, must be ob-
served.

Airbag system
such as the properties of the object the vehi-
c l
e hits
(hard/soft), angle of impact, vehicle
speed, etc.
Deceleration trajectory is key for airbag acti-
vation.
The control unit analyses the collision trajec-
tory and activates the respective restraint
system.
If the deceleration rate is below the prede-
fined reference value in the control unit the
airbags will not be triggered, even though
the accident may cause extensive damage to
the car.
The following airbags are triggered in seri-
ous head-on collisions:
● Driver airbag.
● Front passenger front airbag
● Knee airbag for the driver.
The fol
lowing airbags are triggered in seri-
ous side-on collisions:
● Front side airbag on the side of the acci-
dent.
● Re

ar side airbag on the side of the acci-
dent.
● Cur

tain (head) airbag on the side of the ac-
cident. In an ac

cident with airbag activation:
● the interior lights switch on (if the interior
light swit
ch is in the courtesy light position);
● the hazard warning lights switch on;
● all doors are unlocked;
● the fuel supply to the engine is cut.

Transporting children safely
Transporting children safely Saf ety
f
or children
Introduction For safety reasons, as we have learned from
acc
ident

statistics, we recommend that chil-
dren under 12 years of age travel in the rear
seats. Depending on their age, height and
weight, children travelling in rear seats must
use a child seat or a seat belt. For safety rea-
sons, the child seat should be installed in the
rear seat, behind the front passenger seat or
in the centre back seat.
The physical laws involved and the forces
acting in a collision apply also to children
››› page 82. But unlike adults, children do not
have fully developed muscle and bone struc-
tures. This means that children are subject to
a greater risk of injury.
To reduce the risk of injuries, children must
always use special child restraint systems
when travelling in the vehicle.
We recommend the use of child safety prod-
ucts from the SEAT Original Accessories Pro-
gramme, which includes systems for all ages
made by “Peke” (not for all countries).
These systems have been especially de-
signed and approved, complying with the
ECE-R44. regulation. Follow the manufacturer's instructions and
ob
ser

ve any statutory requirements when in-
stalling and using child seats. Always read
and note ››› page 91.
We recommend you always carry the manu-
facturer's Child Seat Instruction Manual to-
gether with the on-board documentation.
Important information regarding the
front p
assenger's airbag Read the additional information carefully
› ›
›

 page 25.
Read and always observe the safety informa-
tion included in the following chapters:
● Safety distance with respect to the passen-
ger airbag ›

›› page 85.
● Objects between the passenger and the
pas
senger side airbag ››› in Front airbags
on p ag
e 87
.
The passenger side front airbag, when ena-
bled, is a serious risk for a child that is facing
backward since the airbag can strike the seat
with such force that it can cause serious or
fatal injuries. Children up to 12 years old
should always travel on the rear seat.
Therefore we strongly recommend you to
transport children on the rear seats. This is
the safest location in the vehicle. Alternative-
ly, the front passenger airbag can be disa- bled with a key-operated switch
›››
page 89.
When transporting children, use a child seat
suitable for the age and size of each child
››› page 92. WARNING
● If a c hi

ld seat is secured to the front pas-
senger seat, the risk to the child of sustain-
ing critical or fatal injuries in the event of an
accident increases.
● An inflating front passenger airbag can
strike the r
ear-facing child seat and project it
with great force against the door, the roof or
the backrest.
● Never install a child seat facing backwards
on the front p
assenger 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. If the
passenger seat has a height adjustment op-
tion, move it to the highest, most upright po-
sition. If you have a fixed seat, do not install
any child restraint system in this location.
● 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.
● All vehicle occupants, especially children,
must
assume the proper sitting position and
be properly belted in while travelling. » 91

Safety
●
Never ho l
d children or babies on your lap,
this can 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
child 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 80.
● Only one child may occupy a child seat

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. WARNING
The risk of accidents is high when tow-start-
ing, f or e

xample, the towed vehicle can easily
be driven into the towing vehicle. CAUTION
If there is no oil in the gearbox or no lubricant
in the autom atic

transmission the car may
only be towed with the driven wheels lifted
clear of the road, or transported on a special
car transporter or trailer. CAUTION
Do not tow a vehicle for more than 50 m in at-
tempt t

o start it. There is risk of damage to
the catalytic converter. Note
● Ple a

se observe related legal requirements.
● Switch on the hazard warning lights of both
vehicl

For technical reasons, towing the following
vehicles is not allowed:
● Vehicles with an automatic gearbox.
● If the vehicle battery is discharged, be-
cau se in

vehicles with the Keyless Access
locking and ignition system the steering re-
mains locked and the electronic parking
brake cannot be deactivated nor can the elec-
tronic lock of the steering column be re-
leased if they are activated.
● If the battery is flat, it is possible that the
engine contr
ol units may not operate correct-
ly.
However, if the vehicle must absolutely be
tow-started (in the case of manual gearbox-
es):
● Engage the 2nd or 3rd gear.
● Keep the clutch pressed down.
● Switch on the ignition and the hazard warn-
ing lights. ●
Once both v
ehicles are moving, release the
clutch.
● Once the engine starts, press the clutch
and diseng
age the gear to avoid colliding
with the towing vehicle. Note
The vehicle can only be tow-started if the
electr onic

parking brake and, if appropriate,
the electronic lock of the steering column are
deactivated. If the vehicle has no power sup-
ply or there is an electric system fault, the
engine must be tow-started to deactivate the

Introduction In general, a fuse can be assigned to various
electric
al

components. Likewise, an electrical
component can be protected by several
fuses.
Only replace fuses when the cause of the
problem has been solved. If a newly inserted
fuse blows after a short time, you must have
the electrical system checked by a special-
ised workshop as soon as possible. WARNING
The high voltages in the electrical system can
give seriou s

electrical shocks, causing burns
and even death!
● Never touch the electrical wiring of the igni-
tion syst
em.
● Take care not to cause short circuits in the
electrica
l system. WARNING
Using unsuitable fuses, repairing fuses or
bridging a c urr

ent circuit without fuses can
cause a fire and serious injury. ●
Never u se a f

use with a higher value. Only
replace fuses with a fuse of the same amper-
age (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple
or simil
ar. CAUTION
● To pr ev

ent damage to the vehicle's electric
system, before replacing a fuse always turn
off the ignition, the lights and all electrical
elements and remove the key from the igni-
tion.
● If you replace a fuse with higher-rating
fuse,
you could cause damage to another part
of the electrical system.
● Protect the fuse boxes when open to pre-
vent the entr
y of dust or humidity as they can
damage the electrical system. Note
● One component m

ay have more than one
fuse.
● Several components may run on a single
fuse. 101
