Driver assistance systems
WARNING (Continued)
● In complex driving conditions, the Front Assist may unnecessarily
warn and act unintentionally on the brakes, such as, for example, in the
case of traffic islands.
● If the operation of the Front Assist is impaired, for example, because
of dirt or because the radar sensor has lost its setting, the system may
issue unnecessary warnings and act inappropriately on the brakes.
● The ACC does not react during driving to people or animals or vehi-
cles changing lane or approaching in the opposite direction in the same
lane.
● The driver must always be ready to take control of the vehicle again.
Note
● When the Front Assist causes a braking, the brake pedal is “harder”.
● Automatic interventions in the Front Assist braking may be interrupted
by pressing the clutch pedal, accelerator or moving the steering wheel.
● If the Front Assist does not work as described in this chapter (e.g. if it
intervenes several times unnecessarily), switch it off. Have the system
checked by a specialised workshop. SEAT recommends visiting a SEAT deal-
ership. Warning lamps and messages on the display

Driver assistance systems
If the driver does not react to a collision hazard, the system can automati-
cally brake the vehicle by progressively increasing braking pressure to re-
duce speed in the event of a collision. The system can thus help to reduce
the consequences of an accident.
Status display
Automatic deceleration by the City emergency braking function is shown on
the instrument panel display by means of a pre-warning message
⇒ Fig. 140 1)
.
WARNING
The smart technology included in the City emergency braking function
cannot defy the laws of physics. The driver is always responsible for
braking in time.
● Always adapt speed and safety distance to the vehicle ahead accord-
ing to visibility, weather, road and traffic conditions.
● The City emergency braking function alone cannot prevent accidents
or serious injury.
● In complex driving conditions, the City emergency braking function
may act on the brakes, for example, in areas with road works or metal
rails.
● If the City emergency braking function is impaired, for example, be-
cause of dirt or because the radar sensor has lost its setting, the system
may issue unnecessary warnings and act inappropriately on the brakes.
● The City emergency braking function does not react during driving to
people or animals or vehicles changing lane or approaching in the oppo-
site direction in the same lane.
Note
● When the City emergency braking function causes a braking, the brake
pedal is “harder”.
● Automatic interventions in the City emergency braking function may be
interrupted by pressing the clutch pedal, accelerator or moving the steering
wheel.
● The City emergency braking function can decelerate the vehicle and
bring it to a standstill. However, the brake system does not halt the vehicle
permanently. Use the foot brake!
● If several inappropriate interventions take place, disconnect the Front
Assist and with it the City emergency braking function. Visit a specialised
workshop, SEAT recommends a SEAT dealer.
● If numerous unfounded interventions occur the City emergency braking
function may disconnect automatically 

Introduction
SEAT Drive Mode enables the driver to choose between four profiles or
modes, normal, sport, eco and individual , that modify the behaviour of vari-
ous vehicle functions, providing different driving experiences.
The profiles, normal, sport and eco are fixed. Individual can be configured
according to personal preferences. 
Description
Depending on the equipment fitted in the vehicle, SEAT Drive Mode can op-
erate on the following functions:
Engine
Depending on the profile selected, the engine responds more spontaneous-
ly or more in harmony with the movements of the accelerator. Additionally,
when eco mode is selected, the Start-stop function is automatically activa-
ted.
In vehicles with DQ transmission, the gear change points are modified to
position them in lower engine speed ranges ( eco) or higher (sport). Addi-
tionally, eco mode activates the Inertia function, enabling the consumption
to be further reduced.
In manual vehicles, eco mode causes the gear recommendation indications
that appear on the instrument panel to vary, facilitating more efficient driv-
ing.
Dynamic chassis control (DCC)
The DCC adapts the suspension continually during driving to the character-
istics of the road and to the driving situation according to the presettings. 

Driver assistance systems
● Your speed and driving style must always be adjusted to visibility,
weather, and traffic conditions.
● The eco mode is not available when towing a trailer. 
Tiredness detection (break
recommendation)* Introduction
The Tiredness detection informs the driver when their driving behaviour
shows signs of fatigue.
Additional information and warnings:
● Easy Connect system ⇒ page 79
● Accessories, change a part, repairs and adjustments (information stored
in the control units) ⇒ page 272
WARNING
Do not let the comfort afforded by the Tiredness detection system tempt
you into taking any risks when driving. Take regular breaks, sufficient in
length when making long journeys.
● The driver always assumes the responsibility of driving to their full
capacity.
● Never drive if you are tired.
● The system does not detect the tiredness of the driver in all circum-
stances. Consult the information in the section ⇒ page 214, System limi-
tations.
WARNING (Continued)
● In some situations the system may incorrectly interpret an intended
driving manoeuvre as driver tiredness.
● No warning is given in the event of the effect called microsleep!
● Please observe the indications on the instrument panel and act as is
necessary.
Note
● Tiredness detection has been developed for driving on motorways and
well paved roads only.
● If there is a fault in the system, have it checked by a specialised work-
shop. 
Function and operation
Fig. 145 On the instru-
ment panel display:
Tiredness detection sym-
bol
Tiredness detection determines the driving behaviour of the driver when
starting a journey, making a calculation of tiredness. This is constantly com-
pared with the current driving behaviour. If the system detects that the driv-
er is tired, an audible warning is given with a sound and an optic warning is
shown with a symbol and complementary message on the instrument panel 

For the sake of the environment
Under-inflated tyres lead to increased fuel consumption and tyre wear.
Note
● Driving for the first time with new tyres at a high speed can cause them
to slightly expand, which could then produce an air pressure warning.
● Only replace used tyres with those authorised by SEAT for the corre-
sponding type vehicle.
● Do not only rely on the tyre monitoring system. Regularly check your
tyres to ensure that the tyre pressure is correct and that the tyres are not
damaged due to puncture, cuts, tears and impacts/dents. Remove objects
from the tyres only when they have not pierced the tyres. 
Tyre monitor indicator warning lamp


The pressure in one or more
tyres has clearly reduced in
comparison to the tyre pres-
sure set by the driver or the
tyre has structural damage.
Additionally, an audible warn-
ing can be heard and a text
message can be seen on the
instrument panel display. Stop the vehicle! Reduce
speed immediately! Stop the
vehicle safely as soon as pos-
sible. Avoid sudden manoeu-
vres and braking! Check all
tyres and pressures. Replace
any damaged tyres.
flashesPossible causeSolution

System malfunction. The con-
trol lamp flashes for about one
minute and then lights up per-
manently.
If the tyre pressure is correct,
switch the ignition off and on
again. If the control lamp re-
mains lit up, the tyre monitor-
ing indicator can be calibra-
ted. Have the system reviewed
by a specialised workshop.
Several warning and control lamps light up for a few seconds when the igni-
tion is switched on while the function is verified. They will switch off after a
few seconds.
WARNING
When the tyres are inflated at different pressures or at a pressure that is
too low then a tyre may be damaged resulting in a loss of control of the
vehicle and a serious or fatal accident.
● If the warning lamp  lights up, stop immediately and check the
tyres.
● If the tyres are inflated at different pressures or if a tyre pressure is
too low, this will increase tyre wear, negatively affecting vehicle stability
and increasing braking distances.
● If tyres are inflated at different pressures or a tyre pressure is too low,
a tyre may be damaged and burst resulting in a loss of control of the ve-
hicle.
● The driver is responsible for ensuring that all of the vehicle tyres are
correctly inflated to the right pressure. The recommended tyre pressure
is indicated on the label ⇒ page 307.
● The tyre monitoring system can only operate correctly if all of the
tyres are inflated to the correct pressure when cold. 

Wheel tread change
The wheel tread changes when:
● Tyre pressure is manually changed
● Tyre pressure is insufficient
● Tyre structure is damaged
● The vehicle is unbalanced because of a load
● The wheels on an axle are subject to a heavier load (e.g. when towing a
heavy load)
● The vehicle is fitted with snow chains
● The temporary spare wheel is fitted
● The wheel on one axle is changed
There may be a delay in the reaction of the tyre monitoring indicator  or it
may not indicate anything under certain circumstances (e.g. sporty driving,
snow-covered or unpaved roads, or when driving with snow chains). 
Calibrating the tyre monitoring indicator
Fig. 147 Glove compart-
ment: tyre control switch After changing the tyre pressure or replacing one or more wheels, the tyre
monitoring indicator must be recalibrated. Do the same, for example, when
the front and rear wheels are swapped.
●
Switch the ignition on.
● Store the new tyre pressure in the Easy Connect system with the button

and the function button Setup ⇒ page 80 or using the switch located in
the glove compartment* ⇒ Fig. 147.
When driving, the system self-calibrates the tyre pressure provided by the
driver and the wheels fitted. After a long journey with varied speeds the pro-
grammed values are collected and monitored.
With the wheels under very heavy loads, the tyre pressure must be in-
creased to the total recommended tyre pressure before the calibration
⇒ page 307.
Note
● The tyre monitoring indicator does not function when there is a fault in
the ESC or ABS ⇒ page 222.
● An erroneous indication may be given when snow chains are in use be-
cause the chains increase the tread of the wheel. 
Parking aid General information
Various systems are available to help you when parking or manoeuvring in
tight spaces, depending on the equipment fitted on your vehicle.
The rear parking aid is an audible assistant that warns about obstacles lo-
cated behind the vehicle ⇒ page 218. 
