The essentials
Make sure the battery clamps have sufficient
met al-t
o-met
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 270.
● The battery providing assistance must have
the same v
oltage as the flat battery (12V) 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
positive terminals are connected. Changing the wiper blades

Safety
position must always be maintained with

s fastened while travelling.
● 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.
● Never drive 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 loudspeakers or other equip-
ment are fitted inside the door panels.
● Occupants of the outer seats must never
carry
any objects or pets in the deployment
space between them and the airbags, or al-
low children or other passengers to travel in
this position. It is also important not to at-
tach any accessories (such as cup holders) to
the doors. This would impair the protection
offered by the side airbags.
● The built-in coat hooks should be used only
for lightweight
clothing. Do not leave any
heavy or sharp-edged objects in the pockets.
● Great forces, such as hard blows or kicks,
must
not be exerted upon the backrest bol-
ster because the system may be damaged. In
this case, the side airbags would not be trig-
gered. ●
Under no cir c

umstances should protective
covers be fitted over seats with side airbags
unless the covers have been approved for use
in your vehicle. Because the airbag deploys
from the side 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. Head-protection airbags*

 page 24. 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 w
ith se

at 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 must be no other persons, animals or
obj
ects 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.88

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

 page 69.
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
es. However, observe any regulations
to the contrary. 98
