s
ages may be viewed on the instrument
panel display. These may be purely informa-
tive or they may be advising of the need for
action ››› page 104, Instruments.
Depending upon the equipment fitted in the
vehicle, instead of a warning lamp, some-
times a symbol may be displayed on the in-
strument panel.
When certain control and warning lamps are
lit, an audible warning is also heard. WARNING
If the warning lamps and messages are ignor-
ed, the v ehic

le may stall in traffic, or may
cause accidents and severe injuries.
● Never ignore the warning lamps or text
mess
ages.
● Stop the vehicle safely as soon as possible.
● Park the vehicle away from traffic and en-
sure th
at there are no highly flammable ma-
terials under the vehicle that could come into
contact with the exhaust system (e.g. dry
grass, fuel).
● A faulty vehicle represents a risk of acci-
dent for the driv
er and for other road users. If
necessary, switch on the hazard warning
lamps and put out the warning triangle to ad-
vise other drivers.
● Before opening the bonnet, switch off the
engine and al
low it to cool. ●
In any

vehicle, the engine compartment is a
hazardous area and could cause severe inju-
ries ››› page 246. CAUTION
Failure to heed the control lamps and text

Operation
WARNING
Reduced visibility through the windows in-
cr e
ases the risk of serious accidents.
● Always ensure that all windows are free of
ice and sno
w, and that they are not fogged,
so as to maintain good visibility of everything
outside.
● The maximum heat output required to de-
fros
t windows as quickly as possible is only
available when the engine has reached its
normal running temperature. Only drive when
you have good visibility.
● Always ensure that you use the heating
syst
em, fresh air system, air conditioner and
the heated rear window to maintain good visi-
bility to the outside.
● Never leave the air recirculation on for a
long period of time. If
the cooling system is
switched off and air recirculation mode
switched on, the windows can mist over very
quickly, considerably limiting visibility.
● Switch air recirculation mode off when it is
not requir
ed. WARNING
Stuffy or used air will increase fatigue and re-
duce driv er c

oncentration possibly resulting
in a serious accident.
● Never leave the fresh air fan turned off or
use the air rec
irculation for long periods of
time; the air in the vehicle interior will not be
refreshed. CAUTION
● Swit c

h the air conditioner off if you think it
may be broken. This will avoid additional
damage. Have the air conditioner checked by
a specialised workshop.
● Repairs to the air conditioner require spe-
cia
list knowledge and special tools. SEAT rec-
ommends visiting a SEAT Official Service. Note
● When the coo lin

g system is turned off, air
coming from the outside will not be dried. To
prevent fogging of the windows, SEAT recom-
mends leaving the cooling system (compres-
sor) turned on. To do this, press the button  . The button lamp should light up.
● The maximum heat output required to de-
fro s

t windows as quickly as possible is only
available when the engine has reached its
normal running temperature.
● Keep the air intake slots in front of the
winds
creen free of snow, ice and leaves to en-
sure heating and cooling are not impaired,
and to prevent the windows from misting
over. Adjust using the Easy Connect sys-

Diesel engines can take a few seconds longer
than usual to start on cold days. Therefore
the clutch pedal (manual gearbox) or the
brake pedal (automatic gearbox) must re-
main pressed until the engine starts up. Dur-
ing preheating, the warning lamp  remains
lit.
The preheating time depends on the coolant
and exterior temperatures. With the engine at
operating temperature, or at outside temper-
atures above +8°C, the warning lamp  will light up for about one second. This means
that the en

gine starts immediately.
If the engine does not immediately start up,

Driving
When accelerating, the gearbox automatical-
ly shif
ts
up into the next gear shortly before
the maximum engine speed is reached.
If you select a lower gear, the automatic gear-
box will not shift down until there is no risk of
overrevving the engine.
When the kick-down feature is used, the
gearbox shifts down to a lower gear, depend-
ing on road speed and engine speed.
Driving tips The gearbox changes gear ratios automatical-
ly

Operation
Applying both the iner ti
a mode (= prolonged
section with less energy) and the switching
off using inertia (= shorter section without
the need for fuel) facilitates improved fuel
consumption and emission balance. WARNING
● If the iner ti

a mode has been switched on,
take into account, when approaching an ob-
stacle and releasing the accelerator pedal,
that the vehicle will not decelerate in the usu-
al manner: risk of accident!
● When using inertia mode while travelling
down hil
ls, the vehicle can increase speed:
risk of accident!
● If other users drive your vehicle, warn them
about inerti
a mode. Note
● Inerti a mode i

s only available in eco (SEAT
Drive Profile*) driving mode.
● The driver message Inertia is on
ly dis-
played with the current consumption. In iner-
tia mode the gear will no longer be displayed
(for example “E” will appear instead of “E7”).
● On downhill sections with gradients above
15 %, the inertia mode w
ill automatically be
switched off temporarily. Backup programme
A backup programme is in place if a fault

cur in the control system.
If all the positions of the selector lever are
shown over a light background on the instru-
ment panel display, there is a system fault
and the automatic gearbox will operate in
with the backup programme. When the back-
up programme is activated, it is possible to
drive the vehicle, however, at low speeds and
within a selected range of gears. In some ca-
ses driving in reverse gear may not be possi-
ble. CAUTION

Operation
A cold engine consumes a disproportionate
amou nt
of
fuel. The engine reaches its work-
ing temperature after about four kilometres
(2.5 miles), when fuel consumption will re-
turn to a normal level.
Check tyre pressure
Always make sure the tyres are inflated to the
correct pressures ››› page 256 to save fuel. If
the pressure is below half bar, fuel consump-
tion may increase by 5%. Due to the greater
rolling resistance, under-inflation also increa-
ses tyre wear and impairs handling.
Do not use winter tyres all year round as they
increase fuel consumption by up to 10%.
Avoid carrying unnecessary loads
Given that every kilo of extra weight will in-
crease the fuel consumption, it is advisable
to always check the luggage compartment to
make sure that no unnecessary loads are be-
ing transported.
Since the luggage rack increases the aerody-
namic drag of the vehicle, you should remove
it when not needed. This will save, at a speed
of 100-120 km/h (60-75 mph), 12% of fuel.
Save electrical energy
The engine drives the alternator, thereby gen-
erating electricity. This implies that any in-
crease in power consumption also increases
fuel consumption! For this reason, switch off any unneeded electrical devices. Devices that
use a lot of
electricity includes the blower at
a high setting, the rear window heating or
the seat heating*. Driver assistance systems
Br ak
in
g and stability systems
Electronic Stability Control (ESC) The ESC helps to improve safety. It reduces
the tendency
t

o skid and improves the stabil-
ity and roadholding of the vehicle. The ESC
detects critical handling situations, such as
vehicle understeer or oversteer, or wheelspin
on the driving wheels. It stabilises the vehi-
cle by braking individual wheels or by reduc-
ing the engine torque. The warning lamp will
flash on the instrument panel when the ESC
is intervening .
ESC includes the Anti-lock brake system
(ABS), the brake assist system, the traction
control system (ASR), electronic differential
lock (EDL), electronic self-locking*, selective
torque control* and tractor-trailer sway miti-
gation*. ESC also helps stabilise the vehicle
by changing the torque.
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up un-
der braking until the vehicle has reached a
virtual standstill. You can continue to steer
the vehicle even when the brakes are on full.
Keep your foot on the brake pedal and do not
pump the brakes. You will feel the brake ped-
al pulsate while the ABS is working.
