2016 Seat Toledo check engine light

The essentials
water and at least 40 % of the additive G13
(TL -
VW
774 J), purple. This mixture gives the
necessary frost protection down to -25°C
(-13°F) and protects the light alloy parts of
the engine cooling system against corrosion.
It also prevents scaling and considerably rai-
ses the boiling point of the coolant.
To protect the cooling system, the percentage
of additive must always be at least 40 %,
even in warm climates where anti-freeze pro-
tection is not required.
If for weather reasons further protection is
necessary, 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 optimal anti-corro-
sion protection. The mixture of G13 with G12
plus (TL-VW 774 F), G12 (red) or G11 (green-
blue) engine coolants will significantly re-
duce anti-corrosion protection and should
therefore be avoided.

Safety
frontal collision the system might not trigger
corr
ectly
or may fail to trigger at all. Airbag activation
The airbags deploy extremely rapidly, within
thous
andths

of a second, to provide addi-
tional protection in the event of an accident.
A fine dust may develop when the airbag de-
ploys. This is normal and it is not an indica-
tion of fire in the vehicle.
The airbag system is only ready to function
when the ignition is on.
In special accidents instances, several air-
bags may activate at the same time.
In the event of minor head-on and side colli-
sions, rear-end collisions, overturning or roll-
over of the vehicle, airbags do not activate.
Activation factors
The conditions that lead to the airbag system
activating in each situation cannot be gener-
alised. Some factors play an important role,
such as the properties of the object the vehi-
cle hits (hard/soft), angle of impact, vehicle
speed, etc.
Deceleration trajectory is key for airbag acti-
vation. The control unit analyses the collision trajec-
tor
y

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
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. Airbag and seat belt tensioner control
lamp  The control lamp monitors all airbags and
seat
belt

tensioners in the vehicle, including
control units and wiring connections.
Monitoring of airbag and belt tensioner sys-
tem
Both the airbag and belt tensioner systems
operation is constantly monitored electroni-
cally. Each time the ignition is switched on,
the control lamp  illuminates for several
seconds (self-diagnosis) and the instrument
panel display* shows AIRBAG/TENSIONER.
The system must be checked when the con-
trol lamp  :
● does not light up when the ignition is
swit c

hed on,
● turns off after 4 seconds after the ignition
is sw
itched on
● turns off and then lights up again after the
ignition is sw
itched on
● illuminates or flashes while the vehicle is
movin
g.
In the event of a malfunction, the warning
lamp stays on continuously. In addition, de-
pending on the malfunction, a fault message
appears on the instrument panel display for
approximately 10 seconds and a short audi-
ble warning is given. In this event, you

This is for your own safety and that of
other drivers.
● If you have a flat tyre, stop the vehicle as
far aw
ay as possible from moving traffic. Stop
on flat, solid ground.
● If you have to change the tyre on a gradi-
ent, block
the wheel opposite the wheel be-
ing changed by placing a stone or similar ob-
ject under it to prevent the vehicle from roll-
ing away unexpectedly.
● If the vehicle has been fitted with tyres or
allo
ys that are different to those fitted in
manufacture, the instructions ››› page 217,
New tyres or wheels must be followed.
● Always raise the vehicle with the doors
closed.
● Nev

er place parts of your body, e.g. arms
and leg
s, underneath the vehicle when it is
supported only by the jack.
● Secure the base of the jack with suitable
suppor
ts so that it cannot slip. The jack could
slide if the ground below it is soft and slip-
pery and the vehicle could slip off it. There-
fore, place the jack on a firm surface or use a
large, stable base. On a slippery surface, e.g.
tile, use a non-slip base such as a rubber
mat.
● Never start the engine when the vehicle is
jack
ed. Risk of injury.
● The jack should only be used in the correct
jack
ing points. CAUTION
● The pre s

cribed tightening torque for wheel
bolts on steel and alloy wheels is 120 Nm.
● If the anti-theft wheel bolt is overly tight-
ened, this c
ould damage the bolt and the
adapter. Note
● The set of anti-thef

t wheel bolts or the
adapter are available from authorised SEAT
dealers.
● Please observe the relevant local legal reg-
ulation
s when changing the wheel. Wheel bolts
The wheel
bolts
ar
e m
atched to the rims.
When installing different wheels, e.g. to fit
light alloy wheels or wheels with winter tyres,
it is important to use the correct wheel bolts
with the right length and correctly shaped
bolt heads. This is essential for a secure fit of
the wheels and for proper operation of the
brake system. Note
● Never gr e

ase or oil the wheel bolts!
● If the wheel bolt is very tight, it may be
poss
ible to loosen it by pushing down the
end of the box spanner carefully with your foot. Hold on to the vehicle for support and
tak
e c

are not to slip.
● If you notice that the wheel bolts are rusty
and difficult
to turn when changing a wheel,
they must be replaced before having the
tightening torque checked. Tyre repairs

Introduction Due to the constant updating of vehicles,
fu
se a

ssignments based on equipment and
the use of the same fuse for various electrical
components, it is not possible to provide an
up-to-date summary of the fuse positions for
the electrical components at the time this
manual was printed. For detailed information
about the fuse positions, please consult a
technical service.
In general, a fuse can be assigned to various
electrical 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.

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 use a fuse with a higher value. Only
repl
ace 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. 80

Emergencies
Full-LED headlight system*
F u
l
l-LED headlights handle all light functions
(daylight, side light, turn signal, dipped
beam and route light) with light emitting di-
odes (LEDs) as a light source.
Full-LED headlights are designed to last the
lifetime of the car and light bulbs cannot be
replaced. In case of headlight failure, go to
an authorised workshop to have it replaced.
Double headlight bulb change
Changing bulbs requires a certain degree of
practical skill. If in doubt, we recommend you
have defective bulbs changed by a special-
ised service or, in case of an emergency,
seek professional assistance.
● Switch off the ignition and all of the lights
before c
hanging a bulb.
● Do not touch the glass part of the bulb with
your bar
e hands. The fingerprints left on the
glass will vaporise as a result of the heat gen-
erated by the bulb, reducing bulb life and
causing condensation on the reflector sur-
face, thus reducing effectiveness.
● A bulb must only be replaced by one of the
same type. The type i
s indicated on the bulb,
either on the glass part or on the base.
● There is a storage area for the bulb box in
the spar
e wheel well or below the carpet in
the luggage compartment. WARNING
● Tak e p

articular care when working on com-
ponents in the engine compartment if the en-
gine is warm. Risk of burns.
● Bulbs are highly sensitive to pressure. The
glas
s can break when you touch the bulb,
causing injury.
● When changing bulbs, please take care not
to injure
yourself on sharp parts in the head-
light housing. CAUTION
● Remo v

e the ignition key before working on
the electric system. Otherwise, a short circuit
could occur.
● Switch off the lights and the parking light
before c
hanging a bulb. For the sake of the environment
Please ask your specialist retailer how to dis-
pose of u

sed bulbs in the proper manner. Note
● Dependin g on w

eather conditions (cold or
wet), the front lights, the fog lights, the rear
lights and the turn signals may be temporari-
ly misted. This has no influence on the useful
life of the lighting system. By switching on
the lights, the area through which the beam
of light is projected will quickly be demisted.
However, the edges may continue to be mis-
ted. ●
Ple a

se check at regular intervals that all
lighting (especially the exterior lighting) on
your vehicle is functioning properly. This is
not only in the interest of your own safety,
but also that of all other road users.
● Before changing a bulb, make sure you
have the c
orrect new bulb.
● Do not touch the glass part of the bulb with
your bar
e hands, use a cloth or paper towel
instead. Otherwise, the fingerprints left on
the glass will vaporise as a result of the heat
generated by the bulb, they will be deposited
on the reflector and damage its surface. Double headlight bulbs
