tries it is now obligatory, for example, to turn
on the hazard warning lights and use a re-
flective safety vest ››› page 70.
If your vehicle breaks down: Park the vehicle a safe distance from
traffic and on s

uitable ground ››› .

When leaving the vehicle, take all keys
with you.
Place an emergency warning triangle to
indicate the position of your vehicle to

Allow the engine to cool and check if a
specialist is required.
When being towed with the hazard warning
lights on, a change in direction or traffic lane
can be indicated as usual using the turn sig-

A faulty vehicle in traffic represents a risk of
acc ident
for the driver and for other road
users.
● Stop the vehicle safely as soon as possible.
Park the
vehicle a safe distance from sur-
rounding traffic to lock all the doors in case of
an emergency. Turn on the hazard warning
lights to warn other road users.
● Never leave children or disabled people
alone in the v
ehicle if the doors are to be
locked. In case of an emergency, passengers
will be trapped inside the vehicle. Individuals
locked in the vehicle can be exposed to very
high or very low temperatures. WARNING
The components of the exhaust system reach
ver y

high temperatures. This could cause a
fire and considerable damage.
● Always park your vehicle so that no part of
the exhau
st system can come in contact with
flammable materials (such as dried grass or
fuel). Note
● The v ehic

le battery will discharge and run
down if the hazard warning lights remain on
for too long (even with the ignition turned
off). 106

sporting objects
Introduction Always transport heavy loads in the luggage
comp
ar

tment and place the seat backs in a
vertical position. Never overload the vehicle.
Both the carrying capacity as well as the dis-
tribution of the load in the vehicle affect driv-
ing behaviour and braking ability ››› .
WARNING
Unsecured or incorrectly secured objects can
cau se seriou

s injury in case of a sudden ma-
noeuvring or breaking or in case of an acci-
dent. This is especially true when objects are
struck by a detonating airbag and fired
through the vehicle interior. To reduce the
risks, please note the following:
● Secure all objects in the vehicle. Always
keep equipment and he
avy objects in the lug-
gage compartment.
● Always secure objects with suitable rope or
sling
s so that they cannot enter the deploy-
ment areas around the frontal or side airbags
in case of sudden braking or an accident.
● Always ensure that objects inside the vehi-
cle c
annot move into the deployment area of
the bags while driving. ●
Whil e driv

ing, always keep object compart-
ments closed.
● Remove all objects from the front passen-
ger seat
when it is folded down. When the
seat backrest is folded down, it presses on
small and light objects and these are detec-
ted by the weight sensor on the seat; this
sends false information to the airbag control
unit.
● While the backrest of the front passenger
seat i
s folded, the frontal airbag must remain
disconnected and the PASSENGER AIRBAG
OFF  light on.
● Objects secured in the vehicle should never
be plac
ed in such a way as to make passen-
gers sit in an incorrect position.
● If secured objects occupy a seat, this seat
should not
be occupied or used by anyone. WARNING
The driving behaviour and braking ability
ch an

ge when transporting heavy and large
objects.
● Adjust your speed and driving style to visi-
bility
, road, traffic and weather conditions.
● Accelerate gently and carefully.
● Avoid sudden braking and manoeuvres.
● Brake early. Transporting the load
Secure all objects in the vehicle
● Distribute the load throughout the vehicle
and on the roof a

s uniformly as possible.
● Transport heavy objects as far forward as
poss
ible in the luggage compartment and
lock the seat backs in the vertical position.
● Check the headlight adjustment
›››
page 103.
● Use the suitable tyre pressure according to
the load bein
g transported. Read the tyre in-
flation information label ›››
page 200. CAUTION
Objects on the shelf could chafe against the
wir e

s of the heating element in the heated
rear window and cause damage. Note
Please refer to the notes on loading the roof

Driving with the rear lid open creates an addi-
tion
al
ri

sk. Secure all objects and secure the
rear lid correctly and take all measures possi-
ble to reduce toxic gases from entering the
vehicle.
114

Transport and practical equipment
WARNING
Driving with the rear lid unlocked or open
cou l
d cause serious injuries.
● Always drive with the rear lid closed.
● Secure all objects in the vehicle. Loose
items c
ould fall out of the vehicle and injure
other road users or damage other vehicles.
● Drive particularly carefully and think
ahead.
● A

void sudden manoeuvres and braking giv-
en that thi
s could cause an uncontrolled
movement of the open rear lid.
● When transporting objects that protrude
out of the lug
gage compartment, indicate
them suitably. Observe legal requirements.
● If objects must project out of the luggage
compar
tment, the rear lid must never be used
to “secure” or “attach” objects.
● If a baggage rack is fitted on the rear lid, it
should be r
emoved before travelling with the
rear lid open. WARNING
Toxic gases may enter the vehicle interior
when the re ar lid i

s open. This could cause
loss of consciousness, carbon monoxide poi-
soning, serious injury and accidents.
● To avoid toxic gases entering the vehicle al-
way
s drive with the rear lid closed.
● In exceptional circumstances, if you must
drive with the r
ear lid open, observe the fol- lowing to reduce the entry of toxic gases in-
side the
v

ehicle:
– Close all windows.
– Disable air recirculation mode.
– Open all of the air outlets on the instru-
ment panel.
– Switch on the blower to maximum. CAUTION
An open boot hatch changes the length and
height of the

vehicle. Driving a loaded vehicle
For the best handling when driving a loaded
v
ehic
l

e, note the following:
● Secure all objects ›››
page 114.
● Accelerate gently and carefully.
● Avoid sudden braking and manoeuvres.
● Brake early.
● If necessary, read the instructions for driv-
ing with a r
oof carrier system ››› page 127. WARNING
A sliding load could considerably affect the
st ab

ility and safety of the vehicle resulting in
an accident with serious consequences.
● Secure loads correctly so they do not move. ●
When tran s

porting heavy objects, use suit-
able ropes or straps.
● Lock the seat backs in vertical position. Practical equipment
Introduction Storage compartments must only be used to
st
or

e light or small objects. WARNING
In the event of sudden braking movements or
turn s, loo

se objects may be thrown around
the vehicle interior. This could cause serious
injuries to passengers and cause the driver to
lose control of the vehicle.
● Do not transport animals or place hard,
heavy or sh
arp objects inside the vehicle in:
open storage compartments, dash panel, rear
shelf, items of clothing or bags.
● While driving, always keep object compart-
ments c
losed. WARNING
Objects falling into the driver's footwell could
prev ent

use of the pedals. This could lead the
driver to lose control of the vehicle, increas-
ing the risk of a serious accident. » 115

though the interior during a sudden driving
or braking manoeuvre or in the event of an
accident, and could cause injuries.
● The infotainment system holder must be

● The infotainment system must always be
properly sec
ured in its holder or stored safely
in the vehicle. CAUTION
If tilt and angle of visibility are not properly

Transport and practical equipment
CAUTION
At very high or very low temperatures the
smar tphone might
not operate properly, or
the actual device could get damaged.
● Take your smart phone with you when you
get out
of the vehicle to protect it from very
high or very low temperatures, and from in-
tense solar radiation. CAUTION
Humidity can damage the electrical contacts
for the sm ar

tphone on the instrument panel.
● Do not wet the smartphone’s housing when

aning it. Use only a dry cloth. Note
SEAT recommends that you always take your
smar t

phone with you when you get out of
the vehicle to avoid possible thefts. Luggage compartment

WARNING
When the vehicle is not in use or being
wat c

death.
● Do not leave children unwatched, especial-

● Remove hard, heavy and sharp objects from
clothes

store securely. WARNING
The transport of heavy object changes vehi-

andling and increases braking distance.
Heavy loads that have not been stored or se-
cured correctly could cause loss of control
and result in serious injury.
● Vehicle handling changes when transport-
