In vehicles without SEAT Drive Profile

, the be-

haviour of the ACC can also be affected if
any of the following drive profiles are selec-
ted in the infotainment system in 

Drive assist

.

ACC settings will be the same as those in the
SEAT Drive Profile.

WARNING

Before driving off, check that the road is
clear. The radar sensor may not detect ob-
stacles on the road. This could cause an
accident and serious injuries. If necessary,
apply the brake.

CAUTION

If you increase speed using the accelerator
pedal, the ACC may not be able to safely
adjust the speed of the distance due to the
limitations of the system.

Be prepared to react if required by the

situation.

You can cancel this regulation by changing
the set speed or by pressing the accelerator
pedal.

The function works at speeds over 80 km/h
(50 mph). It may not be available in certain
countries.

Overtaking

When the turn signal is switched on for over-
taking, the ACC reduces the distance from
the vehicle in front to help with the overtaking
manoeuvre. The set cruising speed will not be
exceeded.

The function works at speeds over 80 km/h
(50 mph). It may not be available in certain
countries.

vehicles moving in the same direction. There-
fore it does not detect:

People

Animals

»

223

Driving

Vehicles travelling in the opposite direction

or crossing the road.

Other stationary obstacles

The ACC does not react to stationary vehi-
cles. If, for example, a vehicle detected by the
ACC turns or moves over and there is a sta-
tionary vehicle in front of it, the ACC will not
react to the second vehicle 

›››

.

If the brakes overheat, regulation stops au-

tomatically. Wait for them to cool down and
check the operation again.

Unusual noises during automatic ACC

braking are normal and do not indicate any
anomalies.

The following conditions may lead the
ACC not to react:

The accelerator or brake is depressed.

No gear is engaged or the vehicle is in gear

R

.

The vehicle is reversing.

The driver is not wearing his/her seat belt.

A vehicle or trailer brake light is faulty.

The RPM is too high or too low.

The parking brake is applied.

Driving on an excessive slope.

Lane Assist

Introduction

The Lane Assist System helps the driver
stay in his/her lane within the physical lim-
its of the system. This function is not suita-
ble and is not designed to keep the vehicle
automatically in the lane.

Using the camera located in the windscreen,
the Lane Assist system detects the limits (lane
lines) dividing the lanes in which the vehicle is
travelling. If the vehicle gets too close to the
detected lane limits, the system alerts the
driver through a corrective motion of the
steering wheel. The driver can cancel the
steering corrective action at any time.

No warning is produced with the turn signals
activated, given that the Lane Assist system
understands that a lane change is required.

System limits

Use the Lane Assist system only on large,
well-maintained motorways and highways.

The system is not available under the follow-
ing conditions:

The driving speed allowed is below approx.

55 km/h (30 mph).

The system has not detected any lane

lines.

224

Driver assistance systems

On tight bends.

Temporarily in very sporty driving situations.

WARNING

The intelligent technology in the Lane As-
sist system cannot change the limits im-
posed by the laws of physics and by the
very nature of the system. Careless or un-
controlled use of the Lane Assist system
may cause accidents and injury. The sys-
tem is not a replacement for driver aware-
ness or manoeuvres when driving.

Always adapt your speed and the dis-

tance to the vehicles ahead in line with visi-
bility, weather conditions, the condition of
the road and the traffic situation.

Always keep your hands on the steering

wheel so it can be turned at any time. The
responsibility of staying in the lane is al-
ways the driver's.

The Lane Assist system does not detect

all road markings. The road surfaces, road
structures or objects in poor condition can
be incorrectly detected as road markings
under certain circumstances by the Lane
Assist system. Immediately counter any un-
wanted intervention of the system.

Please observe the indications on the in-

strument panel and act as is necessary if
the traffic situation permits.

In the following situations there may be

undesired interventions of the system or it
may be that the system does not intervene

at all. In these situations, special attention
is required from the driver and, where ap-
propriate, the temporary deactivation of
the lane assist warning system:

In very sporty driving situations.

In adverse weather conditions and
roads in poor condition.

When passing through areas undergo-
ing works.

Before gradient changes of grade and
river beds.

Always observe the vehicle surroundings

carefully and drive proactively.

When the area of vision of the camera

becomes dirty, covered or is damaged, the
Lane Assist system function can be affec-
ted.

Driving

or the assistant systems menu after pressing
the corresponding button. The Lane Assist
system can be activated and deactivated in
these menus.

The Lane Assist system is ready to actively in-
tervene as of approximately 60 km/h (35
mph) and if it has detected the lane limits
(system status: active). The control lamp 

emits a green light. When the system inter-
venes by rectifying the direction, the control
lamp 

 emits a yellow light.

If the control lamp of the instrument panel
display is off, it means that the Lane Assist
system is connected but not ready to inter-
vene or it is disconnected.

When you activate a turn signal, the system
temporarily goes into a passive state in order
to allow manual lane change.

An energetic rotation or rectification of the
steering wheel by the driver causes the sys-
tem to temporarily switch to a passive state.

Driver intervention prompt

If the steering is not corrected manually, the
system prompts the driver through an indica-
tion on the instrument panel display and
acoustic warnings.

If no reaction is obtained from the driver, the
system switches to a passive state.

Regardless of the steering manoeuvres,
through an indication on the instrument panel

display and acoustic warnings, the driver is
also prompted to drive through the centre of
the lane if the steering correction lasts more
than reasonable.

Steering wheel vibration

The following situations may result in a steer-
ing wheel vibration:

The lane ceases to be recognised during a

sudden intervention in the direction of the
system.

It is also possible to select steering wheel vi-
bration in the 

Assistants

 menu of the infotain-

ment system. In this case, when a vehicle with
Lane Assist switched on crosses over a detec-
ted lane marking, the steering wheel will vi-
brate.

Troubleshooting

Driving Assist (Travel Assist)

Introduction

The driving assist (Travel Assist) combines
adaptive cruise control (ACC) and adap-
tive lane guidance. Within the limitations
of the system, the vehicle can maintain a
distance from the vehicle in front that is
preselected by the driver and remain in
the preferred position within the lane.

Travel Assist uses the same sensors as Adap-
tive Cruise Control (ACC) and Lane Assist.
Therefore, carefully read the information
about the ACC 

››› 

page 219

 and the Lane As-

sist 

››› 

page 224

 and take into account the

limitations of the systems and the indications
given in the information.

226

Driver assistance systems

Speed range

Travel Assist adjusts at speeds between ap-
prox. 30 km/h (approx. 20 mph) and approx.
210 km/h (approx. 130 mph); in the case of
the adaptive lane guidance function, be-
tween 0 km/h (0 mph) and approx. 250 km/h
(approx. 155 mph).

Driving with Travel Assist

Travel Assist automatically controls the ac-
celerator pedal, the brakes and the steering.
In addition, Travel Assist may, within its limita-
tions, decelerate the vehicle until it stops be-
hind another that stops and automatically
starts again.

You can override assisted adjustment at all
times.

How to know if the vehicle is fitted with
Travel Assist

The vehicle is fitted with Travel Assist if the
multifunction steering wheel has the button

 

››› 

Fig. 157

.

Driver intervention prompt

If you remove your hands from the steering
wheel, after a few seconds the system asks
you to take over the steering with an indica-
tion on the instrument panel display and
acoustic warnings.

WARNING

The Travel Assist smart technology cannot
overcome the limits imposed by the laws of
physics and it only works within the limits of
the system. If Travel assist is used negli-
gently or involuntarily, it may cause serious
accidents and injuries. The system is not a
replacement for driver awareness.

Bear in mind the system limitations and

the indications regarding the control of the
Adaptive Cruise Control (ACC) and Lane
Assist.

Adapt your speed and safety distance to

the vehicle in front of you at all times to suit
visibility, weather, road and traffic condi-
tions.

Do not use Travel Assist when visibility is

bad, on steep roads, on windy roads or in
slippery circumstances (such as snow, ice,
rain or loose gravel), or on flooded roads.

Do not use Travel Assist offroad or on

roads where the surface is not firm. Travel
Assist has been designed for use on paved
roads only.

Travel Assist does not react to people or

animal or vehicles crossing your path or
which approach you head-on in the same
lane.

Brake immediately if Travel Assist does

not slow down enough.

Brake immediately when a braking mes-

sage is displayed on the instrument panel
screen.

Brake when, after an indication to brake,

the vehicle rolls without it being desired.

Keep your hands on the steering wheel at

all times, to ensure you have control over
the steering at all times. The driver is al-
ways responsible for keeping the vehicle in
its own lane.

If possible, do not wear gloves while driv-

ing. The system could interpret this as no
driving activity.

If driver intervention is requested on the

instrument panel display, immediately re-
sume control of the vehicle.

Always be prepared to adjust the speed

yourself.

Side Assist with Rear Cross
Traffic Alert (RCTA)

Introduction

The lane departure warning (LCA) helps de-
tect traffic that is at the rear of the vehicle.

The rear cross traffic alert (RCTA) helps the
driver when backing out of a parallel parking
spot and when manoeuvring.

WARNING

The smart technology incorporated into
the blind spot detector (BSD) with parking
assistance (RCTA) included cannot over-
come the limits imposed by the laws of
physics; it only works within the limits of the
system. Accidents and severe injury may

occur if the blind spot detection system or
the rear cross traffic alert are used negli-
gently or involuntarily. The system is not a
replacement for driver awareness.

Adapt your speed and safe distance to

the vehicle in front of you at all times to suit
visibility, weather, road and traffic condi-
tions.

Keep your hands on the wheel at all times

to be ready to intervene in the steering at
any time.

Pay attention to the indicator lamps that

may come on in the external rear view mir-
rors and on the instrument cluster, and fol-
low any instructions they may give.

The lane departure warning could react

to any special constructions that might be
present to the sides of the vehicle, e.g. high
or irregular dividers. This may cause erro-
neous warnings.

Never use the lane departure warning on

unpaved roads. The lane departure warn-
ing has been designed for use on paved
roads.

Always pay attention to the vehicle's sur-

roundings.

The control lamps of the lane departure

warning may have limited functionality due
to solar radiation.

Note

If the blind spot detector with parking as-
sistant does not work as described in this
chapter, stop using it and contact a speci-
alised workshop.

It lights up

It turns on once briefly: the lane departure warning is

activated and ready to operate, i.e. when activating
the system.

It lights up continuously: the lane departure warning
has detected a vehicle in the blind spot.

Flashes

A vehicle has been detected in the adjacent lane and

the turn signal has been engaged in the direction of

the detected vehicle 

››› 

.

For vehicles that are also equipped with Lane Assist

››› 

page 224

, a warning to switch lanes will also ap-

pear even though the turn signal has not been en-
gaged (Lane Assist “Plus” 

››› 

page 231

).

The control lamps light up when the ignition is
switched on and should turn off after approxi-
mately 2 seconds. This is the time taken for
the function check.

If there are no indications from the control
lamp of the lane departure warning, this
means that the lane departure warning has
not detected any other vehicles at the rear
area 

››› 

.

When the exterior lighting is low, the intensity
with which the control lamps come on is dim-
med. The user can modify the intensity of the
control lamps with up to 5 levels in the info-
tainment system menu.

WARNING

Failure to pay attention to any lit warning
lamps and the corresponding messages
could cause serious accidents and injuries.

Never ignore the warning lamps or mes-

sages.

Carry out the necessary operations.

CAUTION

Failure to heed the control lamps and cor-
responding text messages when they light
up may result in damage to the vehicle.

Lane departure warning (Side As-
sist)

The lane departure warning uses radar sen-
sors to monitor the areas behind the vehicle

››› 

page 8

. The system does this by measur-

ing the vehicle's distance from other vehicles
and its speed differential. The lane departure
warning will not work at speeds of less than
approx. 15 km/h (9 mph). The system uses
optical signals in the external rear view mir-
rors to notify the driver.

The lane width is not detected individually,
but is rather pre-configured in the system.
Thus if you are driving in wide lanes or in be-
tween two lanes, the indications may be in-
correct. Furthermore, the system can detect

230

Driver assistance systems

vehicles driving in the lane next to you (if
there are any), and can also detect station-
ary objects such as dividers, and thus give an
incorrect indication.

Indication on the exterior mirror

The control lamp provides an indication on
the corresponding side regarding the traffic
situation behind the vehicle, if it is deemed to
be critical. The control lamp on the left-hand
side indicates the traffic situation to the rear
left of the vehicle, and the control lamp on
the right-hand side indicates the traffic situa-
tion to the rear right of the vehicle 

››› 

Fig. 158

.

In the case of retrofitted tinted windows or
windows with tinted film, the indications of the
external mirrors may not be seen clearly or
correctly.

Keep the external mirrors clean and free of
snow and ice, and do not cover them with ad-
hesives or other similar materials.

Driving

The faster a vehicle approaches, the sooner
an indication will be displayed in the exterior
mirror, because Side Assist takes into account
the different in speed compared to other ve-
hicles. Thus even though the distance from
the other vehicle is identical, the indication
will appear sooner in some cases and later in
others.

Physical limitations inherent to the system

In some situations the lane departure warning
may not interpret the traffic situation correct-
ly. I.e. in the following situations:

on tight bends;

in the case of lanes with different widths;

in areas with significant gradient changes;

in adverse weather conditions;

in the case of special constructions to the

side of the vehicle, e.g., high or irregular divid-
ers.

may sound if the relevance so requires it.

In addition to the acoustic alarm, the driver is
also informed by means of a visual signal on
infotainment system display. This signal is dis-

played in the form of a red or yellow strip at
the back of the image of the vehicle on the in-
fotainment system screen. This strip displays
the side of the vehicle towards which traffic is
approaching in transverse direction

Automatic braking to reduce damages

If the rear cross traffic alert detects that
someone else on the road is approaching the
rear of the vehicle and the driver does not
step on the brake, the system will engage the
brakes automatically.

The parking system helps the driver by auto-
matically engaging the brakes to reduce any
damage. The automatic intervention on the
brakes takes place when driving in reverse at
approx. 1-12 km/h (1-7 mph). After detecting
that the vehicle is stationary, the system
keeps it that way for around 2 seconds.

After automatically braking to reduce dam-
age, the system will not be able to automati-
cally brake again for approximately 10 sec-
onds.

You can interrupt the automatic braking by
stepping hard on the accelerator pedal or
the brake pedal in order to regain control of
the vehicle.

Driver assistance systems

WARNING

The smart technology incorporated into
the rear cross traffic alert cannot over-
come the limits imposed by the laws of
physics; it only works within the limits of the
system. The parking assistant function
should not tempt you into taking any risks.
The system is not a replacement for driver
awareness.

The system should never be used in limi-

ted visibility conditions or complicated
traffic, e.g., in high-traffic areas or when
crossing multiple lanes.

Be sure to always be aware of the vehi-

cle's surroundings, since the system often
fails to detect things such as bicycles or
pedestrians.

The rear cross traffic alert itself will not

brake the vehicle to a complete stop.

Managing the assist systems

Enabling and disabling the assist systems

The blind spot detector with parking assistant
can be switched on and off by accessing the

Assistants

 menu on the dash panel display

using the steering wheel controls. If the vehi-
cle is equipped with a multifunction camera,
it can also be accessed by means of the as-
sistants systems key located on the main
beam headlight lever.

Open the 

Assistants

 menu.

 Side Assist

 Rear cross traffic alert

If the verification box on the instrument panel
or the infotainment system is checked 

, the

functionality will be automatically activated
when switching on the ignition.

When the Side Assist is ready to operate, the
indicator turns on briefly on the exterior rear
view mirrors as confirmation.

When the vehicle is restarted, the last adjust-
ment in the system will remain active.

Trailer mode

Side Assist and the rear cross traffic alert are
automatically deactivated and cannot be
switched on if the factory-fitted tow-bar is
electrically connected to a trailer or similar
device.

As soon as the driver starts to drive with a
trailer connected electrically to the vehicle, a
message is displayed on the instrument pan-
el display indicating that the Side Assist and
the rear cross traffic alert are switched off.
Once the trailer has been unhooked from the
vehicle, if you want to use the Side Assist and
the rear cross traffic alert, you will have to re-
activate them in the corresponding menu.

If the tow-bar is not factory fitted, Side Assist
and the rear cross traffic alert should be

switched off manually when driving with a
trailer.

WARNING

When the ignition is switched on, the sta-

tus of the brake system and the brake as-
sist functions is automatically checked.
The control lights on the instrument cluster
light up briefly and then turn off again. If a
warning light stays on permanently, there
is a fault. Seek qualified technical assis-
tance immediately.

If the brake warning lamp 

 does not go

out or if it lights up when driving, the brake
fluid level in the reservoir is too lo so there
is a risk of an accident

Obtain technical assistance.

If the brake warning lamp lights up 

 to-

gether with the ABS lamp 

 this could be

due to an ABS fault. When this function
fails, the rear wheels can lock up. Under
certain circumstances, the rear of the vehi-
cle may skid, with the danger of losing con-
trol. Stop and seek technical assistance.

Information about the brakes

New brake pads

For the first 200 to 300 km (100 to 200
miles), new brake pads have not yet reached
their maximum braking capacity, and need to
be “run in” first. However, you can compen-
sate for the slightly reduced braking effect by
applying more pressure on the brake pedal.
Avoid overloading the brakes while running
them in.

Wear

The rate of wear on the 

brake pads

 depends

a great deal on how you drive and the condi-
tions in which the vehicle is operated. This is a
particular problem in urban traffic and short
stretches, or with very sporty driving.

Depending on the speed, the braking force
and the environmental conditions (e.g. tem-
perature, air humidity, etc.) noises may be
produced when braking.

Wet roads or road salt

In certain situations (for example, on driving
through flooded areas, in severe downpours
or after washing the vehicle) the braking ac-
tion could be delayed if the discs and pads
are damp, or frozen in winter. In this case the
brakes should be “dried” by pressing the
brake pedal several times.

At high speed and with the windscreen wipers
activated, the brake pads will briefly touch
the brake discs. This takes place, although
unnoticeable to the driver, at regular intervals
to improve the response time of the brakes
when they are wet.

The effectiveness of the brakes can also be
temporarily reduced if the vehicle is driven for
some distance without using the brakes when
there is a lot of salt on the road in winter. The
layer of salt that accumulates on the discs
and pads can be removed by gently apply-
ing the brakes a few times.

Corrosion

There may be a tendency for corrosion to
form on the discs and dirt to build up on the
brake pads if the vehicle is used infrequently
or the brakes are not used very often.

If the brakes are not used frequently, or if rust
has formed on the disks, it is advisable to
clean off the pads and disks by braking firmly
a few times at a moderately high speed

Braking and parking

Fault in the brake system

If the brake pedal travel should ever increase

suddenly

, this may mean that one of the two

brake circuits has failed. Drive immediately to
the nearest specialised workshop and have
the fault repaired. Drive there slowly and re-
member that you will have to apply more
pressure on the brake pedal and allow for
longer stopping distances.

Low brake fluid level

Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake fluid
level is monitored electronically.

Brake servo

The brake servo increases the pressure you
apply to the brake pedal. It works only when
the engine is running.

WARNING

Any anomaly in the brake system can in-
crease the braking distance, with the re-
sulting risk of an accident.

New brake pads and discs must be run in

and do not have the correct friction during
the first 200 km (124 miles). This reduced
braking capacity may be offset by pressing
on the brake pedal a little harder.

If you are driving on roads which have

been salted, braking effectiveness may be
decreased.

Brakes can overheat if used excessively

on slopes. Before driving down a long steep
slope, it is advisable to reduce speed and
change down into a lower gear or range.
Therefore, using the engine brake relieves
the brakes.

Gentle continuous braking causes the

brakes to overheat and the braking dis-
tance will increase. Apply and then release
the brakes alternately.

Apply the brakes heavily to clean the

brake system only in a suitable traffic situa-
tion. Do not put other road users in danger:
there is risk of causing an accident.

Ensure the vehicle does not move while in

neutral, when the engine is stopped. The
braking distance is increased considerably
when the brake servo is not active.

If the brake is subjected to high stresses,

vapour bubbles may form in the brake sys-
tem's pipes. This reduces the efficiency of
the brakes.

Non-standard or damaged front spoilers

could restrict the airflow to the brakes and
cause them to overheat. Before purchasing
accessories please read the relevant in-
structions.

CAUTION

Never let the brakes “drag” by leaving

your foot on the pedal when it is not neces-
sary to brake. This overheats the brakes, re-

sulting in longer stopping distances and
greater wear.

Before driving down a long, steep gradi-

ent, it is advisable to reduce speed and se-
lect a lower gear. This makes use of engine
braking and relieves the brakes. If you still
have to use the brakes, it is better to brake
firmly at intervals than to apply the brakes
continuously.

Note

If the brake servo is out of action, for ex-

ample when the car is being towed, you will
have to press the brake pedal considerably
harder than normal to make up for the lack
of servo assistance.

If you wish to equip the vehicle with ac-

cessories such as a front spoiler or wheel
covers, it is important that the flow of air to
the front wheels is not obstructed, other-
wise the brakes can overheat.
