Hazard warning lights Fig. 139
Dash panel: switch for hazard warn-
in g lights. Read the additional information carefully
› ›

 page 26
The hazard warning lights are used to draw
the attention of other road users to your vehi-
cle in emergencies.
If your vehicle breaks down:
1. Park your vehicle at a safe distance from movin
g traffic.
2. Press the button to switch on the hazard warning lights
››› .
3. Switch the ignition off.
4. Apply the handbrake.
5. For a manual gearbox, engage 1st gear; for an aut
om

atic gearbox, move the gear
lever to P. 6. Use the warning triangle to draw the atten-
tion of other ro
ad users to your vehicle.
7. Always take the vehicle key with you when you le
ave the vehicle.
All turn signals flash simultaneously when
the hazard warning lights are switched on.
The two turn signal turn signal lamps  
and the turn signal lamp in the switch  will
flash at the same time. The hazard warning
lights also work when the ignition is switch-
ed off.
Emergency braking warning
If the vehicle is braked suddenly and continu-
ously at a speed of more than 80 km/h (50
mph), the brake light flashes several times
per second to warn vehicles driving behind. If
you continue braking, the hazard warning
lights will come on automatically when the
vehicle comes to a standstill. They switch off
automatically when the vehicle starts to
move again. WARNING
● The risk of

an accident increases if your ve-
hicle breaks down. Always use the hazard
warning lights and a warning triangle to draw
the attention of other road users to your sta-
tionary vehicle.
● Due to the high temperatures that the cata-
lytic con
verter can reach, never park in an
area where the catalytic converter could come into contact with highly inflammable materi-
al
s, f

or example dry grass or spilt petrol. This
could start a fire. Note
● The b atter

y will run down if the hazard
warning lights are left on for a long time,
even if the ignition is switched off.
● The use of the hazard warning lights de-
scribed her
e is subject to the relevant statu-
tory requirements. Parking lights
When the parking light is switched on, (right
or l
ef
t

turn signal), the front side light and
the rear light on the corresponding side of
the vehicle stay lit. The parking lights can on-
ly be activated with the ignition switched off
and the turn signal and main beam lever in
the central position, before being triggered.
Parking light on both sides With the ignition switched off and the light

c

h in position , when locking the vehi-
cle from the outside, the parking lights on
both sides of the vehicle light up. In doing
so, only the side lights of both headlights
light up, and additionally the tail lights will
do so partially.

Operation
Motorway light* The motorway light is available on vehicles
equipped w
ith f
ull-LED lights.
The function is connected/disconnected via
the corresponding Easy Connect system
menu.
● Activation: when going abo
ve 110 km/h for
more than 30 seconds, the dipped beam rai-
ses slightly to increase the distance of visibil-
ity of the driver.
● Deactivation: when reduc in
g the speed of
the car below 100 km/h, the dipped beam re-
turns to its normal position.
Driving abroad The light beam of the dipped beam lights is
a
symmetric: the s
ide of

the road on which
you are driving is lit more intensely.
When a car that is manufactured in a country
that drives on the right travels to a country
that drives on the left (or vice versa), it is nor-
mally necessary to cover part of the headlight
bulbs with stickers or to change the adjust-
ment of the headlights to avoid dazzling oth-
er drivers.
In such cases, the regulations specify certain
light values that must be complied with for
designated points of the light distribution.
This is known as “Tourist light”. The light distribution that the halogen and
ful

l-LED headlights of the SEAT Leon range
have allows the specific “tourist light” values
to be met without the need for stickers or
changes in the settings. Note
“Tourist light” is only allowed temporarily. If
you ar e p

lanning a long stay in a country that
drives on the other side, you should take the
vehicle to an Authorised Technical Service to
change the headlights. Headlight range control, lighting of

When the ignition is switched on the heated
windscreen washer jets automatically adjust
the heat depending on the ambient tempera-
ture.
Headlight wash/wipe system
The headlight washers/wipers clean the
headlight lenses.
After the ignition is switched on, the first and
every fifth time the windscreen washer is
switched on, the headlights are also washed. Therefore, the windscreen wiper lever should
be pul

led towards the steering wheel when
the dipped beam or main beam are on. Any
incrusted dirt (such as insects) should be
cleaned regularly (e.g. when refuelling).
To ensure the headlight washers work cor-
rectly in winter, any snow which has got into
the bumper jet supports should be cleaned
away. If necessary, remove snow with an anti-
icing spray. Note
The wiper will try to wipe away any obstacles
that ar

e on the windscreen. The wiper will
stop moving if the obstacle blocks its path.
Remove the obstacle and switch the wiper
back on again. Rain sensor*

o det
ermine the tr

affic situation
››› Fig. 195 1 . This sensor can detect vehi-
c l
e

s in front up to a distance of approximately
120 m.
The radar sensor's visibility may be impaired
by dirt, mud or snow, or by environmental in-
fluences such as rain or mist. In this case the
adaptive cruise control (ACC) does not work.
The instrument panel displays the following
message: ACC: No sensor vision! If
necessary clean the radar sensor ››› .
When the r a
d

ar sensor begins to operate
properly again, the ACC will automatically be
available again. The message on the instru-
ment panel screen will switch off and the ACC
will be reactivated again.
ACC operation may be affected by a strong ra-
dar reverse reflection. This may occur, for ex- ample, in a closed car park or due to the
presenc

e of metallic objects (e.g. rails on the
road or sheets used in road works).
The area in front of and around the radar sen-
sor should not be covered with adhesives,
additional or similar headlights, as this may
negatively affect ACC operation.
If structural modifications are made to the ve-
hicle, for example, if the suspension is low-
ered or the front spoiler is modified, ACC op-
eration may be affected. So structural modifi-
cations should only be made by specialised
workshops. SEAT recommends visiting a SEAT
dealership for this purpose.
If work is done incorrectly on the front of the
vehicle, the radar sensor could be damaged
or lose its settings, and ACC operation may
be affected. So repair work should only be
made by specialised workshops. SEAT recom-
mends visiting a SEAT dealership for this pur-
pose. CAUTION
If you have the sensation that the radar sen-
sor is d

amaged or has lost its settings, dis-
connect the ACC. This will avoid possible
damage. If this occurs have it adjusted.
● The sensor may become damaged or lose
its settin
gs when knocked, for example, dur-
ing a parking manoeuvre. This may compro-
mise the system's efficacy or disconnect it. » 189
