Note
● Inertia mode is only available in eco driving mode (SEAT Drive Mode*).
● The driver message Inertia is only displayed with the current consump-
tion. In inertia mode the gear will no longer be displayed (for example: E will
appear in place of E7).
● On downhill sections with gradients above 15 %, the inertia mode will
automatically be switched off temporarily. 
Backup programme
A backup programme is in place if a fault should occur in the
control system.
If all the positions of the selector lever are shown over a light background
on the instrument panel display, there is a system fault and the automatic
gearbox will operate in with the backup programme. When the backup pro-
gramme is activated, it is possible to drive the vehicle, however, at low
speeds and within a selected range of gears. In some cases driving in re-
verse gear may not be possible .
CAUTION
If the gearbox operates with the backup programme, take the vehicle to a
specialised workshop and have the fault repaired without delay. 
Clutch
 Clutch overheated! Stop the vehicle!
The clutch has overheated and could be damaged. In order to prevent the
temperature from increasing again and so that the clutch is cooled, stop the
vehicle and wait for the gearbox to cool down with the selector lever in posi- tion P and the engine running at idling speed. If the warning does not
switch off, do not continue driving. Seek specialist assistance. Failure to do
so could cause considerable damage to the gearbox. When the warning
switches off, the fault should be corrected by a specialised workshop with-
out delay.

Manual release of the selector lever
The selector lever can be released manually if the electrical
power supply should fail.
Fig. 93 Selector lever:
manual release from po-
sition P
The manual release mechanism is located under the selector lever
console on the right side. Releasing the selector lever requires a
certain degree of practical skill. We therefore advise you to obtain
professional assistance. A screwdriver will be needed to carry out the manual release. Use
the flat part of the screwdriver blade
⇒ page 232.
Removing the cover from the selector lever
– Apply the handbrake  ⇒ 
to ensure that the car does not
move.
– Carefully pull the corners of the selector lever boot and fold up
the selector lever boot (inside out) by hand.
Releasing the selector lever
– Using a screwdriver, press and hold the yellow unlocking tab
sideways ⇒ Fig. 93.
– Now press the interlock button on the selector lever A
and
move the selector lever to position N.
– After carrying out the manual release, attach the selector lever
boot on the gearbox console again.
If the power supply should ever fail (discharged battery, etc.) and the vehi-
cle has to be pushed or towed, the selector lever must first be moved to po-
sition N. This is possible after operating the manual release mechanism.
WARNING
The selector lever may be moved out of position P only when the hand-
brake is firmly applied. If this does not work, secure the vehicle with the
brake pedal. On a slope the vehicle could otherwise start to move inad-
vertently after shifting the selector lever out of position P - accident risk!

Cruise control system (CCS)*
Introduction
The cruise control system (CCS) is able to maintain the set speed from 20
km/h (15 mph).
A constant speed is maintained using the engine power control or by apply-
ing the active brake ⇒ 
.
Additional information and warnings:
● Change gear ⇒ page 154.
● Accessories and technical modifications ⇒ page 230.
WARNING
Use of the cruise control could cause accidents and severe injuries if it is
not possible to drive at a constant speed maintaining the safety distance.
● Do not use the cruise control in heavy traffic, if the distance from the
vehicle in front is insufficient, on steep roads, with several bends or in
slippery circumstances (snow, ice, rain or loose gravel), or on flooded
roads.
● Never use the CCS when driving off-road or on unpaved roads.
● Always adapt your speed and the distance to the vehicles ahead in
line with visibility, weather conditions, the condition of the road and the
traffic situation.
● To avoid unexpected operation of the cruise control system, turn it off
every time you finish using it.
WARNING (Continued)
● It is dangerous to use a set speed which is too high for the prevailing
road, traffic or weather conditions.
● When travelling down hills, the CCS cannot maintain a constant
speed. The vehicle tends to accelerate under its own weight. Select a
lower gear or use the foot brake to slow the vehicle.

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.
Steering
Power steering becomes more robust in sport mode to enable a more sporty
driving style.
Air conditioning
In vehicles with Climatronic, this can operate in eco mode, especially re-
stricting fuel consumption.
Ambient lighting
The ambient lighting guides located in the interior front door panels of the
Leon FR change colour from white to red when sport mode is activated. Setting driving mode
You can select from Normal, Sport, Eco and Individual.
Fig. 100 Centre console:
MODE button
The required mode can be selected on the touch screen, in the menu that
opens when the MODE button is pressed.
An icon on the Easy Connect system display informs about the active mode.
The MODE button light remains lit up yellow when the active mode is differ- ent to normal.

fileCharacteristics
NormalOffers a balanced driving experience, suitable for everyday
use.
SportProvides a complete dynamic performance in the vehicle, en-
abling the user a more sporty driving style. 

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. 101 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
display ⇒ Fig. 101. The message on the instrument panel display is shown
for about 5 seconds, and depending on the case, is repeated. The system
stores the last message displayed.
The message on the instrument panel display can be switched off by press-
ing the 
button on the windscreen wiper lever or the button  on the
multi function steering wheel ⇒ page 73. The message can be recalled to the instrument panel display using the mul-
tifunction display
⇒ page 73.
Conditions of operation
Driving behaviour is only calculated on speeds above about 65 km/h (40
mph) up to around 200 km/h (125 mph).
Switching on and off
Tiredness detection can be activated or deactivated in the Easy Connect
system with the button 
and the function button  ⇒ 
page 79. A mark
indicates that the adjustment has been activated.
System limitations
The Tiredness detection has certain limitations inherent to the system. The
following conditions can limit the Tiredness detection or prevent it from
functioning.
● At speeds below 65 km/h (40 mph)
● At speeds above 200 km/h (125 mph)
● When cornering
● On roads in poor condition
● In unfavourable weather conditions
● When a sporty driving style is employed
● In the event of a serious distraction to the driver
Tiredness detection will be restored when the vehicle is stopped for more
than 15 minutes, when the ignition is switched off or when the driver has
unbuckled their seat belt and opened the door.
In the event of slow driving during a long period of time (below 65 km/h (40
mph) the system automatically re-establishes the tiredness calculation.
When driving at a faster speed the driving behaviour will be recalculated. 

Tyre monitoring systems Introduction
Additional information and warnings:
● SEAT information system ⇒  page 73
● Caring for and cleaning the vehicle exterior ⇒ page 198
● Wheels and tyres ⇒ page 223
● Accessories, parts replacement, repairs and modifications ⇒ page 230
WARNING
Unsuitable handling of the wheels and tyres may lead to sudden tyre
pressure losses, to tread separation or even to a blow-out.
● Check tyre pressures regularly and ensure they are maintained at the
pressures indicated. Tyre pressure that is too low could cause overheat-
ing, resulting in tread detachment or even burst tyres.
● Tyre pressure should be that indicated on the label when the tyres are
cold at all times ⇒ page 266.
● Regularly check the cold inflation pressure of the tyres. If necessary,
change the tyre pressure of the vehicle tyres while they are cold.
● Regularly check your tyres for damage and wear.
● Never exceed the maximum permitted speed or loads specified for the
type of tyre fitted on your vehicle.
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. 

about one minute and then
lights up permanently.
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 re-
viewed by a specialised
workshop. 
