ched on, the seat belt status
display ››› Fig. 10
on the instrument panel in-
forms the driver whether the passengers in
the rear seats have fastened their seat belts.
It indicates that the corresponding seat
is empty.
Indicates that the seat is occupied and
the occupant is wearing the seat belt.
The seat belt status flashes for a maximum of
30 seconds when a seat belt in the rear seats
is unfastened while the vehicle is in motion. An
audible warning will also be heard if the vehi-
cle is travelling at over 25 km/h (15 mph).
If a seat belt is fastened or unfastened while
driving in some of the rear seats, the seat belt
]
i status is displayed for approximately 30 sec-
onds. The indication can be hidden by press-
ing the E

 button on the dash panel.
The protective function of seat
belts Fig. 11
Drivers with properly worn seat belts
will not be thr o

wn forward in the event of sud-
den braking. Properly worn seat belts hold the occupants
in the pr
oper position. They al

so help prevent
uncontrolled movements that may result in
serious injury and reduce the risk of being
thrown out of the vehicle in case of an acci-
dent.
Vehicle occupants wearing their seat belts
correctly benefit greatly from the ability of
the belts to absorb kinetic energy. In addition,
the front part of your vehicle and other pas-
sive safety features (such as the airbag sys- tem) are designed to absorb the kinetic ener-
gy rel

eased in a collision. Taken together, all
these features reduce the releasing kinetic
energy and consequently, the risk of injury.
This is why it is so important to fasten seat
belts before every trip, even when "just driving
around the corner".
Ensure that your passengers wear their seat
belts as well. Accident statistics have shown
that wearing seat belts is an effective means
of substantially reducing the risk of injury and
improving the chances of survival when in-
volved in a serious accident. Furthermore,
properly worn seat belts improve the protec-
tion provided by airbags in the event of an
accident. For this reason, wearing a seat belt
is required by law in most countries.
Although your vehicle is equipped with air-
bags, the seat belts must be fastened and
worn. The front airbags, for example, are only
triggered in some cases of head-on collision.
The front airbags will not be triggered during
minor frontal or side collisions, rear-end colli-
sions, overturns or accidents in which the air-
bag trigger threshold value in the control unit
is not exceeded.
Important safety instructions for
the use of seat belts

Operation
of specific traffic signs for vehicles with trailer,
such as speed limits or o v
ertaking prohibi-
tions. Activation or deactivation is carried out
in the infotainment system using the function
button  > Driver assistance > Trailer as- sist ››› page 96
.
For trailer mode, the display of speed limits
applicable to the type of trailer or to the legal
provisions can be adjusted. The speed is ad-
justed in steps of 10 km/h (5 mph) within a
range of between 60 km/h (40 mph) and
130 km/h (80 mph). If it is adjusted to a speed
greater than that which is permitted in the
country in question for driving with a trailer,
the system automatically displays the usual
speed limits, e.g. in Germany 80 km/h
(50 mph).
If the speed warning for the trailer is deacti-
vated, the system displays the speed limits as
if there were no trailer hitched.
No entry sign
The traffic sign recognition system warns
acoustically and visually in the instrument
panel when a no entry sign is crossed on a
one-way road or an entrance to a motorway
or highway.
Limited operation
The traffic sign detection system has certain
limitations. The following cases may lead the system to operate with limitations or not at
all:

orward drive position
The D/S position enables the gears to be op-
erated in normal mode (D) or sport mode (S).
To select Sport mode S, move the lever back-
wards. Pushing the lever again will select nor-
mal mode D. The selected driving mode is
displayed on the instrument panel screen.
In normal mode (D), the gearbox selects the
best gear ratio. This depends on the engine load, the road speed and the dynamic gear
control pr

ogramme (DCP).
Sport mode (S) should be selected for a
sporty driving style. This setting makes use of
the engine's maximum power output. When
accelerating the gear shifts will be noticea-
ble.
Under certain circumstances (e.g. on moun-
tain roads) it can be advantageous to switch
tiptronic mode ››› page 231
, to adapt the
gears to suit the road conditions.
Selector lever lock
In N, the lever lock prevents a gear range
from being engaged, and prevents the vehi-
cle from moving off accidentally.
Press and hold the brake pedal with your left
foot with the engine running.
As a reminder to the driver, when the lever is
in position N the following indication will be
shown on the screen:
When stationary, apply footbrake
while selecting a gear.
The lever is not locked if it is moved quickly
through position N (e.g. when shifting from R
to D). This makes it possible, for instance, to
“rock the vehicle backwards and forwards” if
it is stuck in snow or mud. The lever lock en-
gages automatically if the brake pedal is not
pressed and the lever is in position N for more than about one second at a speed of less
than 5 km/h (3 mph). WARNING

Start and driving
Description Depending on the equipment fitted in the ve-
hicl
e
, SEAT Drive Profile can operate on the
following functions:
Engine
Depending on the profile selected, the engine
responds more quickly or smoothly to the ac-
celerator being pressed. When the Eco pro-
file is selected, the Start-stop function is acti-
vated.
In vehicles with automatic transmission, the
gear change timing is changed to put the
changes at higher or lower revolutions. The
Eco profile activates the Inertia function,
thereby reducing consumption. The rest of
the driving profiles will activate the inertia use
function when the selector lever is not in the S
position, depending on how the accelerator
pedal is released ››› page 234
. When the ve-
hicle is turned on again, the function is activa-
ted by default to reduce consumption.
With manual transmission, the Eco profile
changes the gear change recommendations
to facilitate more efficient driving.
Dynamic chassis control (DCC)*
The DCC continuously adapts the damping
of the suspension system to the characteris-
tics of the road surface and the driving situa-
tion (speed, acceleration and steering wheel angle) according to the selected driving pro-
fil
e

. The vehicle's dynamic behaviour is also
adapted to improve grip on curves and turn-
ing capacity. Within the Individual profile you
can also adjust the DCC level in a custom-
ised manner.
In the event of a fault in the DCC, the follow-
ing message is displayed on the instrument
screen Fault: shock absorber regula-
tion
Steering
The power steering varies its driving modes
and adapts to the profile selected, thus offer-
ing the best behaviour for each situation.
Air conditioning
The Climatronic can operate in Eco mode
with particularly limited consumption.
Adaptive Cruise Control (ACC)*
Depending on the driving profile, the perform-
ance of the ACC varies, to allow more sporty
acceleration and braking or a more respect-
ful fuel consumption.
PreCrash system
The PreCrash system adapts according to
the selected configuration. The Sport driving
profile has specific settings to adapt to driv-
ing characteristics ››› page 24
. Setting the driving profile There are several ways to select a driving
pr
ofil

e using the infotainment system:

Start and driving
For the sake of the environment
If the engine is run in gently, the life of the
engine will be incr eased and the engine oil
consumption r
educed.Economical and environmentally
friendly driving
Fuel consumption, environmental pollution
and w
ear t

o the engine, brakes and tyres all
depend largely on driving style. Consumption
can be reduced between 10-15% with an effi-
cient driving type. The following section gives
you some tips on lessening the impact on the
environment and reducing your operating
costs at the same time.
Active cylinder management (ACT®)*
Depending on vehicle equipment, the active
cylinder management (ACT®) may deacti-
vate some of the engine cylinders if the driv-
ing situation does not require too much pow-
er. The number of active cylinders can be
seen on the instrument panel display.
››› page 72.
Foresight when driving
If you think ahead when driving, you will need
to brake less and thus accelerate less. Take
advantage of the inertia of the vehicle when-
ever possible, with a gear engaged. This takes advantage of the engine braking effect,
r
educing w

ear on the brakes and tyres. Emis-
sions and fuel consumption will drop to zero.
Changing gear to save energy
An effective way of saving is to change in ad-
vance to a higher gear.
Manual transmission: shift up from first to
second gear as soon as possible. Choosing
the right gear enables fuel savings. Select the
highest possible gear appropriate for the
driving situation (the engine should continue
functioning with cyclical regularity).
Automatic transmission: accelerate gradu-
ally and without reaching the “kick-down”
position.
Avoid driving at high speed
Avoid travelling at your vehicle’s top speed,
whenever possible. Fuel consumption, emis-
sion of harmful gases and noise pollution
multiply as speed is increased. Driving at
moderate speeds will help to save fuel.
Reduce idling time
In vehicles with the Start-Stop system idling is
automatically reduced. In vehicles without
the Start-Stop system it is worth switching off
the engine, for example, at level crossings
and at traffic lights that remain red for long
periods of time. When an engine has reached
operating temperature, and depending on the cylinder capacity, keeping it switched off
for a minimum of about 5 seconds alr
eady
saves more than the amount of fuel necessa-
ry for restarting.
The engine takes a long time to warm up
when it is idling. Mechanical wear and pollu-
tant emissions are also especially high during
this initial warm-up phase. It is therefore best
to drive off immediately after starting the en-
gine. Avoid running the engine at high speed.
Regular maintenance
Regular servicing helps in saving fuel even
before the engine is started. A well-serviced
engine gives you the benefit of improved fuel
efficiency as well as maximum reliability and
an enhanced resale value. A badly serviced
engine can consume up to 10% more fuel
than necessary.
Avoid short journeys
The engine and catalytic converter need to
reach their optimal operating temperature
in order to minimise fuel consumption and
emissions.
A cold engine consumes a disproportionate
amount of fuel. The engine reaches its work-
ing temperature after about four kilometres
(2.5 miles), when fuel consumption will return
to a normal level. »

Driving
Towing bracket device*
T r
ailer mode
Introduction Take into account country-specific regula-
tions about driving with a tr
ail

er and the use
of a towing bracket.
The vehicle has been developed primarily for
carrying people, although it can also be used
to tow a trailer if fitted with the corresponding
technical equipment. This additional load has
an effect on the useful life, fuel consumption
and vehicle performance and in some cases
can reduce the service intervals.
Driving with a trailer requires more force from
the vehicle, and thus more concentration
from the driver.
In winter, winter tyres should be fitted on both
the vehicle and the trailer.
Maximum vertical load technically permit-
ted on the coupling device
The maximum technical permitted vertical
load of the trailer's towing bracket on the
hook of the tow-bar is 80 kg.
Vehicles with the Start-Stop system
If the vehicle has a factory-fitted towing
bracket or one that is retrofitted by SEAT, the Start-Stop system operates as normal. No
special char
act

eristics need to be taken into
account.
If the system does not recognise the trailer or
the trailer bracket has not been retrofitted by
SEAT, the Start-Stop system must be discon-
nected by pressing the corresponding button
in the lower part of the centre console before
driving with the trailer, and it should remain
off for the rest of the journey ››› .
V ehicl

es with driving profile selection
If you are going to be towing a trailer, the use
of the Eco driving profile is not recommen-
ded. You are advised to select another of the
available driving profiles before beginning to
drive with a trailer.
Trailer weight/drawbar load
Never exceed the authorised trailer weight. If
you do not load the trailer up to the maximum
permitted trailer weight, you can then climb
correspondingly steeper slopes.
The maximum trailer weights listed are only
applicable for altitudes up to 1000 m above
sea level. Since higher altitude decreases en-
gine performance and the ability to climb
slopes, the tow load decreases proportional-
ly. The weight of the vehicle and trailer com-
bination must be reduced by 10% for every
1000 m of altitude. When possible, operate
the trailer with the maximum authorised drawbar load on the ball joint of the to

wing
bracket, but do not exceed the specified lim-
it. WARNING
Never use the trailer to transport people,
since it w oul

d put their life in danger and is
also prohibited. WARNING
Undue use of the towing bracket may
cause injury and accidents.
