Driving
Moving off uphill in vehicles with Hill start assistant*
– Once you have engaged a gear, release the footbrake and press
the accelerator ⇒ page 168, Hill driving assistant*.
Driving down hills: In some situations (on mountain roads or when towing a
trailer or caravan) it can be advantageous to switch temporarily to the man-
ual gearbox programme so that the gear ratios can be selected manually to
suit the driving conditions ⇒ 
.
On level ground it is sufficient to move the selector lever to position P. On
slopes, first engage the parking brake and then put the selection lever into
the P position. This avoids overloading the locking mechanism and it will be
easier to move the selector lever from position P.
WARNING
● As a driver you should never leave your vehicle if the engine is run-
ning and a gear is engaged. If you have to leave your vehicle while the
engine is running, you must apply the handbrake and engage the parking
lock P.
● If the engine is running and a gear is engaged (D/S or R) or the vehi-
cle is in tiptronic mode, you will need to hold the car with the footbrake.
Otherwise, the car will creep forwards as the power transmission is not
fully interrupted even when the engine is idling.
● Take care not to accidentally press the accelerator pedal when the ve-
hicle is stopped. The vehicle could otherwise start moving immediately
(in some cases even if the parking brake is engaged) resulting in the risk
of an accident.
● While you are selecting a gear and the vehicle is stopped with the en-
gine running, do not accelerate. Failure to do so could result in an acci-
dent.
● Never move the selector lever to R or P when driving: this could result
in an accident!
WARNING (Continued)
● Before you drive down a steep gradient, reduce your speed and use
tiptronic to select a low gear.
● Never allow the brake to rub and do not use the brake pedal too often
or for long periods. Constant braking causes overheating in the brakes.
This could significantly reduce braking power, increase braking distance
or even result in the total failure of the brake system.
● To avoid rolling back on gradients always hold the vehicle with the
footbrake or handbrake if you have to stop.
CAUTION
● If you stop the vehicle on a gradient, do not attempt to stop it from roll-
ing by depressing the accelerator when a gear has been selected. This
could cause overheating and damage the automatic gearbox. Apply the
handbrake firmly or press the brake pedal in order to prevent the vehicle
from rolling back.
● If you allow the car to roll with the selector lever in position N with the
engine switched off, the automatic gearbox will be damaged as it will not be
lubricated.
● In certain driving situations or traffic conditions, such as frequently
starting, prolonged “creeping” of the vehicle or traffic jams with continuous
stoppages, the gearbox could overheat causing damage! If the warning
lamp  lights up, stop the vehicle as soon as possible and wait for the
gearbox to cool ⇒ page 181.

192Driver assistance systems
On the front bumper there is a radar sensor to detect traffic conditions
⇒ Fig. 131 1
. This sensor can detect vehicles driving ahead at a distance
of up to approx. 120 m.
The radar sensor's visibility may be impaired by dirt, such as mud or snow,
or by environmental influences, such as rain or water mist. In this case the
adaptive cruise control (ACC) does not work. The following message is
shown in the instrument panel display: ACC: Sensor without visibility!. If nec-
essary, clean the radar sensor ⇒ 
.
When the radar sensor works properly again, the ACC will be automatically
available again. The message on the instrument panel display will go off
and the ACC can be switched on again.
ACC operation may be affected by a heavy reverse reflection of the radar sig-
nal. This may occur, for example, in a closed car park or due to the presence
of metal objects (e.g. rails on the road or the panels used on work sites).
The area ahead of and behind the radar sensor should not be covered with
adhesives, additional headlights or the likes, as this may have a negative
effect on ACC operation.
If structural modifications are made to the vehicle, e.g., if the suspension is
lowered or the front spoiler is modified, ACC operation may be affected. This
is why structural modifications should only be assigned to specialised work-
shops. SEAT recommends visiting a SEAT dealership for this.
If the front part of the vehicle is repaired incorrectly, the radar sensor might
lose its setting and ACC operation would be affected. This is why repair jobs
should only be assigned to specialised workshops. SEAT recommends visit-
ing a SEAT dealership for this.
CAUTION
If you have the impression that the radar sensor is damaged or has lost its
setting, disconnect the ACC. This will prevent possible damage. In this case
have it adjusted.
● The sensor may lose its settings if it is knocked, for example, during a
parking manoeuvre. This may compromise the system's efficacy or lead it to
switch off.
● A radar sensor repair requires specialist knowledge and special tools.
SEAT recommends visiting a SEAT dealership for this.
● Snow should be removed with a brush, while ice should be removed
with a solvent-free anti-ice aerosol. 

Message texts
 ACC not available
The system cannot continue to guarantee safe vehicle detection so it is
switched off. The sensor has lost its setting or is damaged. Take the vehicle
to a specialised workshop to have the fault repaired.
 ACC: not available at the moment. Sensor without visibility
 ACC and Front Assist: not available at the moment. Sensor without
visibility
This message for the driver is displayed if the visibility of the radar's sensor
is impaired, e.g., by leaves, snow, heavy mist or dirt. Clean the sensor.
 ACC: not available at the moment. Gradient too steep
The maximum slope has been exceeded, hence it cannot be guaranteed
that the adaptive cruise control will operate safely. The adaptive cruise con-
trol cannot be activated
 ACC: only available in D, S or M
Select the position of the selector lever D/S or M.
 ACC: parking brake applied
The adaptive cruise control is deactivated if the parking brake is applied.
The adaptive cruise control is available again if the parking brake is re-
leased.
 ACC: not available at the moment. Stabilisation control intervention
The message for the driver is shown when the electronic stabilisation con-
trol (ESC) intervenes. In this case, the adaptive cruise control will automati-
cally be switched off.
 ACC: Intervene!
The message for the driver is shown if, when you start up on a gentle slope,
the vehicle moves backwards even although the ACC is switched on. Step on the brake pedal to prevent the vehicle from moving/crashing into anoth-
er vehicle.

ACC: speed limit
The message for the driver is shown in vehicles with manual gearbox if the
current speed is too low for ACC mode.
The speed you wish to store must be at least 30 km/h. The cruise control
system switches off if the speed falls below 20 km/h.
 ACC: available as of the 2nd gear
The adaptive cruise control is operational as of the 2nd gear (manual gear-
box).
 ACC: engine speed
The message for the driver is shown if, when the adaptive cruise control ac-
celerates or brakes, the driver does not go up or down a gear in time, which
would mean either exceeding or not reaching the admissible rpm. The adap-
tive cruise control will then be switched off. A warning buzzer goes off.
 ACC: clutch pressed down
Vehicles with a manual gearbox: press the clutch pedal for longer to exit
control.
  
Three white dots appear if a setting made with the control lever cannot be
executed. For example, the adaptive cruise control cannot be switched on in

Overtaking
When the turn signal comes on before overtaking, the ACC accelerates the
vehicle automatically and thus reduces the distance between it and the ve-
hicle ahead.
When you move into the overtaking lane, if the ACC does not detect any ve-
hicle in front it accelerates until it reaches the stored speed and keeps it
constant.
The acceleration can be interrupted at any time by stepping on the brake
pedal or pulling back on the lever ⇒ page 193.
Driving through a bend
On entering or coming out of a bend, the radar sensor may no longer detect
the vehicle ahead of it or may react before a vehicle in the adjacent lane
⇒ Fig. 136 A. In such situations the vehicle may brake unnecessarily or may
cease to react with regard to the vehicle ahead. In this case, the driver has
to act by accelerating or interrupting the braking process by stepping on the
brake pedal or pulling the third lever backwards ⇒ page 193.
Driving in tunnels
When going through tunnels, the radar sensor function may be limited.
Switch off the ACC in tunnels.
Narrow vehicles or vehicles not driving straight
The radar sensor can only detect narrow vehicles or those that are not driv-
ing straight within its range ⇒ Fig. 136 B. This is particularly applicable to
narrow vehicles such as motorbikes. In these cases, brake yourself as nec-
essary.
Vehicles with loads and special accessories
The load and special accessories of other vehicles that jut out over the side,
backwards or forward may be outside the range of the ACC.
Switch off the ACC when driving behind vehicles with loads or special acces-
sories, as well as when overtaking these vehicles. In these cases, brake
yourself as necessary. Other vehicles changing lanes
Vehicles changing lanes not far away from the vehicle can only be detected
when they fall within the range of the sensors. Consequently, the ACC will
take longer to react
⇒ Fig. 137 C. In these cases, brake yourself if necessary.
Stationary vehicles
During driving, the ACC does not detect stationary objects, such as the end
of a jam or damaged vehicles.
If a vehicle detected by ACC turns or moves over and there is another sta-
tionary vehicle in front of it, the ACC will not react ⇒ Fig. 137 D. In these ca-
ses, brake yourself if necessary.
Vehicles travelling in the opposite direction and vehicles changing lanes
The ACC does not react to vehicles approaching in the opposite direction or
vehicles changing lanes.
Metal objects
Metal objects, e.g. rails on the road or the panels used on work sites, may
confuse the radar sensor and cause wrong reactions in the ACC.
Factors that may affect the operation of the radar sensor
If the operation of the radar sensor were affected by heavy rain, water mist,
snow or mud, the ACC is switched off temporarily. The relevant message ap-
pears on the instrument panel display. If necessary, clean the radar sensor.
When the radar sensor works properly again, the ACC will be automatically
available again. The message on the instrument panel display will go off
and the ACC can be switched on again.
In the event of a heavy reverse reflection of the radar signal, for example, in
a closed parking, ACC operation may be affected.
Trailer towing
When driving with a trailer, the ACC controls less dynamically. 

WARNING
Failure to heed the warning lamps when they light up and the corre-
sponding messages may result in an accident and injury.
● Never ignore the warning lamps or on-screen messages.
Note
When the Front Assist is connected, the instrument panel display messages
pertaining to other functions may be hidden, such as an incoming call. 
Radar sensor
Fig. 139 On the front
bumper: radar sensor.
On the front bumper there is a radar sensor to detect traffic conditions
⇒ Fig. 139 1
. This sensor can detect vehicles driving ahead at a distance
of up to approx. 120 m.
The radar sensor's visibility may be impaired by dirt, such as mud or snow,
or by environmental influences, such as rain or water mist. In this case the Front Assist Monitoring system does not work. The following message is
shown in the instrument panel display:
Front Assist: Sensor without visibili-
ty!. If necessary, clean the radar sensor ⇒ 
.
When the radar sensor works properly again, the Front Assist will be auto-
matically available again. The message will disappear from the instrument
panel display.
Front Assist operation may be affected by a heavy reverse reflection of the
radar signal. This may occur, for example, in a closed car park or due to the
presence of metal objects (e.g. rails on the road or the panels used on work
sites).
The area ahead of and around the radar sensor should not be covered with
adhesives, additional headlights or the like, as this may have a negative ef-
fect on Front Assist operation.
If structural modifications are made to the vehicle, e.g., if the suspension is
lowered or the front spoiler is modified, Front Assist operation may be affec-
ted. This is why structural modifications should only be assigned to special-
ised workshops. SEAT recommends visiting a SEAT dealership for this.
If the front part of the vehicle is repaired incorrectly, the radar sensor might
lose its setting and Front Assist operation would be affected. This is why re-
pair jobs should only be assigned to specialised workshops. SEAT recom-
mends visiting a SEAT dealership for this.
CAUTION
If you have the impression that the radar sensor is damaged or has lost its
setting, disconnect the Front Assist. This will prevent possible damage. In
this case have it adjusted.
● The sensor may lose its settings if it is knocked, for example, during a
parking manoeuvre. This may compromise the system's efficacy or lead it to
switch off. 

Driver assistance systems
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. 
Safety FirstOperating instructionsPractical TipsTechnical specifications

218Driver assistance systems
During parking, the parking system plus assists you visually and audibly
about obstacles detected in front and behind the vehicle ⇒ page 219.
WARNING
● Always pay attention (also when looking straight ahead) to traffic and
the vehicle surroundings. The assistance systems are not a replacement
for driver awareness. When inserting or removing the vehicle from a park-
ing space, or when performing similar manoeuvres the driver always as-
sumes the responsibility.
● Take into account that the system is not always in conditions to rec-
ognise or represent certain surfaces, such as dress fabric: Risk of causing
an accident!
● The sensors and cameras have blind spots, making the detection of
people and objects impossible. Pay special attention to children and ani-
mals: Risk of causing an accident!
● Always keep visual control of the vehicle surroundings: use the rear
vision mirrors for additional help.
CAUTION
● Under certain circumstances, the system does not detect or display cer-
tain objects:
–Objects such as snow chains, trailer draw bars, bars or fences
– Objects that are located above the sensors, such as protrusions in a
wall.
– Objects with certain surfaces or structures, such as wire mesh fences
or powder snow.
● When the vehicle approaches a low obstacle, it could disappear from
the angle of measurement. In this case, take into account that the system
will no longer warn about this obstacle.
● The knocks or damage on the radiator grille, bumper, wheel arch and ve-
hicle underbody can adjust the orientation of the sensors. This can affect
the parking aid function. Have the function checked by a specialised work-
shop.
Note
● In certain situations, the system can give a warning even though there is
no obstacle in the detected area, e.g:
–for roads with certain surfaces, or with long grass
– for external ultrasound sources, such as cleaning vehicles
– In downpours, intense snow or dense exhaust gases
● In order to familiarise yourself with the system, it is advised that you
practice parking in an area or car park that is free from traffic. There must be
good weather and light conditions.
● The volume and tone of the warnings can be modified, in addition to the
indications ⇒ page 221.
● In vehicles without a driver information system, these parameters can be
modified in a SEAT Official Service or in a specialised workshop.
● Please observe information on towing a trailer ⇒  page 221.
● The display on the Easy Connect screen shows a slight time delay.
● To ensure that the parking aid works properly, the sensors must be kept
clean and free of ice and snow. 
Rear parking aid*
