Driving tips Introduction
Always transport heavy loads in the luggage compartment and place the
seat backs in a vertical position. Never overload the vehicle. Both the carry-
ing capacity as well as the distribution of the load in the vehicle have ef-
fects on the driving behaviour and braking ability ⇒ 
.

WARNING
Unsecured or incorrectly secured objects can cause serious injury in case
of a sudden manoeuvring or breaking or in case of an accident. This is es-
pecially true when objects are struck by a detonating airbag and fired
through the vehicle interior. To reduce the risks, please note the follow-
ing:
● Secure all objects in the vehicle. Always keep equipment and heavy
objects in the luggage compartment.
WARNING (Continued)
● Always secure objects with suitable rope or slings so that they cannot
enter the deployment areas around the frontal or side airbags in case of
sudden braking or an accident.
● Always ensure that objects inside the vehicle cannot move into the
deployment area of the bags while driving.
● While driving, always keep object compartments closed.
● Remove all objects from the front passenger seat when this is fol-
lowed down. When the seat backrest is folded down, it presses on small
and light objects and these are detected by the weight sensor on the
seat; this sends false information to the airbag control unit.
● While the backrest of the front passenger seat is folded, the frontal
airbag must remain disconnected and the PASSENGER AIRBAG OFF 
light on.
● Objects secured in the vehicle should never be placed in such a way
as to make passengers sit in an incorrect position.
● If secured objects occupy a seat then this should not be occupied or
used by anybody.
WARNING
The driving behaviour and braking ability change when transporting
heavy and large objects.
● Adjust your speed and driving style to visibility, road, traffic and
weather conditions.
● Accelerate gently and carefully.
● Avoid sudden braking and manoeuvres.
● Brake early.

Loading luggage compartment
Introduction
Always transport heavy loads in the luggage compartment and place the
seat backs in a vertical position. Never overload the vehicle. Both the carry-
ing capacity as well as the distribution of the load in the vehicle have ef-
fects on the driving behaviour and braking ability ⇒ 
.
Additional information and warnings:
● Airbag system ⇒ page 67
● Light ⇒ page 84
● Transporting ⇒ page 97
● Wheels and tyres ⇒ page 210
WARNING
When the vehicle is not in use or being watched, always lock the doors
and the rear lid to reduce the risk of serious injury or death.
● Do not leave children unwatched, especially when the rear lid is open.
Children could climb into the luggage compartment, close the rear lid
from inside and be unable to escape themselves. This could lead to seri-
ous injury or death.
● Never allow children to play in or around the vehicle.
● Never transport people in the luggage compartment.
WARNING
Unsecured or incorrectly secured objects can cause serious injury in case
of a sudden manoeuvring or breaking or in case of an accident. This is es-
pecially true when objects are struck by a detonating airbag and fired
through the vehicle interior. To reduce the risks, please note the follow-
ing:
● Secure all objects in the vehicle. Always keep equipment and heavy
objects in the luggage compartment.
● Always secure objects with suitable rope or straps so that they can-
not enter the deployment areas around the frontal or side airbags in case
of sudden braking or an accident.
● While driving, always keep object compartments closed.
● Do not place hard, heavy or sharp objects inside the interior, in open
storage compartments, the rear shelf or on the dash panel.
● Remove hard, heavy and sharp objects from clothes and pockets in-
side the vehicle and store securely.
WARNING
The transport of heavy object changes vehicle handling and increases
braking distance. Heavy loads that have not been stored or secured cor-
rectly could cause loss of control and result in serious injury.
● The vehicle handling changes when transporting heavy objects due
to a change in the centre of gravity.
● Distribute the load as uniformly and as low down on the vehicle as
possible.
● Store heavy objects in the luggage compartment as far from the rear
axle as possible.
CAUTION
Hard objects on the rear shelf could chafe against the wires of the heating
element in the heated rear window and cause damage. 

106Transporting
Always check the weight of the base support, the roof carrier system and
the weight of the load to be transported and, if necessary, weigh them. Nev-
er exceed the maximum authorised roof load.
If you are using a roof carrier with a lower weight rating, you cannot trans-
port the maximum roof load. Do not exceed the maximum weight limit for
the roof carrier given in the fitting instructions.
Distributing a load
Uniformly distribute loads and secure them correctly ⇒ 
.
Check attachments
After fitting the base supports and the roof carrier system, always check the
attachments after a short trip or at regular intervals.
WARNING
Exceeding the maximum authorised roof load can result in accidents
and/or vehicle damage.
● Always respect the maximum authorised weight for the roof, the max-
imum authorised weight on the axles and the total maximum authorised
weight of the vehicle.
● Never exceed the capacity of the roof carrier system even if this is
less than the maximum authorised roof load.
● Secure heavy objects towards the front and distribute the load even-
ly.
WARNING
Loose and incorrectly secured loads can fall from the roof carrier system
causing accidents and injury.
● Always use suitable ropes and straps in good condition.
● Always secure loads correctly.

138Starting, changing gears, parking
A layer of salt on the discs and brake pads will reduce brake efficiency and
increase braking distance. If you drive for a prolonged period on salted
roads without braking then brake carefully several times to eliminate the
layer of salt on the brakes ⇒ 
.
If the vehicle remains parked for considerable lengths of time, is used little,
or if the brakes are not used, there may be corrosion on the brake discs and
a build-up of dirt on the brake pads. If the brakes are not used frequently, or
if rust has formed on the discs, SEAT recommends cleaning the pads and
discs by braking firmly a few times at a moderately high speed. Only do this
without endangering vehicles behind you or any other road users ⇒ 
.
Faults in the brake system
During braking, if you notice that the vehicle does not react as usual (that
the braking distance has increased suddenly) it may be possible that there
is a fault in the braking system. This is indicated by the warning lamp .
Take the vehicle to a Specialised workshop immediately and have the fault
repaired. Drive at a moderate speed and be prepared to use more pressure
on the brake pedal, and allow for longer braking distances.
Brake servo
The brake servo only operates when the engine is running and the pressure
applied by the driver on the brake pedal increases.
If the brake servo does not operate or the vehicle must be towed, then the
brake pedal will have to be pressed with more force given that the braking
distance will be increased when the brake servo does not operate ⇒ 
.
WARNING
New brake pads do not brake to full efficiency.
● For the first 320 km (200 miles), new brake pads have not yet reached
their maximum braking capacity, and need to be “run in” first. For this, to
compensate for reduced braking efficiency the brake pedal will have to
be pressed with more force.
WARNING (Continued)
● To avoid losing control of the vehicle and causing serious accidents,
always take great care when driving with new brake pads.
● When running in new brake pads, always respect the safety distances
between you and other vehicles and do not cause situations requiring ex-
treme braking performance.
WARNING
When brakes overheat, braking is less efficient and braking distances in-
crease.
● When driving on slopes, brakes can be overloaded and overheat
quickly.
● Reduce speed or reduce the gear when faced with steep and long
slopes. This allows you to use the engine braking effect and to reduce
the strain on the brake system.
● Non-standard or damaged front spoilers could restrict the airflow to
the brakes and cause them to overheat.
WARNING
Wet, frozen or salt-covered brakes take time to brake and this increases
braking distances.
● Test the brakes carefully.
● Dry the brakes, free them of ice and salt by braking gently several
times, when visibility, weather, and road and traffic conditions permit. 

210Vehicle care and maintenance
Wheels and tyres
Introduction
SEAT recommend that all work on tyres and wheels is carried out by a Speci-
alised workshop. They have the necessary special tools and replacement
parts, trained personnel and facilities for disposing of the old tyres. SEAT
recommends visiting a Technical Service.

● Change wheel ⇒ page 250
● Tire Mobility Set ⇒ page 256
WARNING
The vehicle cannot be totally controlled or braked if the tyres (new or
used) are worn or damaged.
● Incorrect use of wheels and tyres could make driving more dangerous
and result in serious accidents and damage.
● All four wheels must be fitted with radial tyres of the same type, size
(rolling circumference) and the same tread pattern.
● New tyres do not give maximum grip and will not have reached their
maximum braking capacity to start with, and therefore need running in.
To prevent accidents and major damage, extreme caution should be tak-
en for the first 600 km (400 miles).
WARNING (Continued)
● Check tyre pressures regularly and ensure they are maintained at the
pressures indicated. If the tyre pressure is too low, the tyres could over-
heat, resulting in tread detachment or even burst tyres.
● Never drive on damaged (punctured, cut, cracked or dented) or worn
tyres. Driving on damaged or worn tyres could result in burst tyres, seri-
ous accidents or damage. Worn or damaged tyres must be replaced im-
mediately.
● Never exceed the maximum permitted speed or loads specified for the
type of tyre fitted on your vehicle.
● The efficiency of driver and brake assist systems also depends on the
grip of the tyres.
● If you notice unusual vibration or if the vehicle pulls to one side when
driving, stop the vehicle immediately and check the tyres and wheels for
damage.
● To minimise the risk of losing control of the vehicle or causing a seri-
ous accident, never undo the bolted joints of beadlock wheels.
● Never mount used tyres or wheels if you are not sure of their previous
history. They may be damaged, although the damage is not immediately
visible.
● Old tyres, even if they have never been used, may lose air or burst un-
expectedly while driving, especially at high speeds, resulting in serious
accident and injury. If tyres are over six years old, they should only be
used in an emergency and with extreme caution.
Note
For technical reasons, it is not generally possible to use the wheels from
other vehicles. In some cases, this may also be true for the same model of
wheel. Please refer to the vehicle documents or ask at a Technical Service. 

213
Vehicle care and maintenance
WARNING
The use of worn or damaged wheel trims could make driving more dan-
gerous and result in serious accidents and damage.
● Only wheel trims which have been approved for use with your vehicle
should be used.
● Inspect wheel trims regularly for damage and replace as required.
WARNING
If the bolted joints of wheel trims with bolted ring trims are not correctly
tightened or loosened, this could result in serious accident.
● Never loosen the bolted joints of wheel trims with bolted ring trims.
● Any work relating to wheel trims with bolted trims should be carried
out at Specialised workshop. SEAT recommends visiting a Technical Serv-
ice.

Replacement of new tyres and wheel trims
New tyres
● When tyres are new, drive with extreme caution for the first 600 km
(400 miles), as all tyres need to be run-in. Tyres which have not been run-in
do not have such good grip ⇒ 
or braking capacity ⇒ .
● All four wheels must be fitted with radial tyres of the same type, size
(rolling circumference) and the same tread pattern.
● The tread depth of new tyres may vary, according to the type and make
of tyre and the tread pattern. Replacing tyres
●
Where possible, always replace both wheels on an axle (both wheels on
the front axle or both wheels on the rear axle) ⇒ 
.
● Only replace used tyres with those authorised by SEAT for the corre-
sponding type vehicle. Pay special attention to size, diameter, and maxi-
mum load and speed capacity.
● Never use tyres which are larger than SEAT approved tyres. If the tyres
are too big, they may knock or rub against the chassis or other components,
resulting in damage.
WARNING
New tyres do not give maximum grip and will not have reached their max-
imum braking capacity to start with, and therefore need running in.
● To prevent accidents and major damage, extreme caution should be
taken for the first 600 km (400 miles).
WARNING
There should be adequate space between the tyres and the vehicle in ac-
cordance with the vehicle design. If this is not the case, the tyres may
rub against parts of the running gear, chassis or brake lines, leading to
faults in the brake system or to tread detachment, and the risk of burst
tyres.
● The true tyre dimension should not be greater than the dimensions of
tyres manufactured and approved by SEAT and should not rub against
parts of the vehicle.
Note
Although tyres may be shown as being the same size, the true dimensions
of different types of tyre may vary with respect to the nominal size, or tread
patterns may be different. 

The letters TIN refer to the tyre serial number.
Tyres with directional tread pattern
Tyres with directional tread pattern have been designed to operate best
when rotating in only one direction. An arrow on the tyre sidewall indicates
the direction of rotation on tyres with directional tread. Always observe the
direction of rotation indicated when mounting the wheel. This guarantees
optimum grip and helps to avoid aquaplaning, excessive noise and wear.
If the tyre is mounted in the opposite direction of rotation, drive with ex-
treme caution, as the tyre is no longer being used correctly. This is of partic-
ular importance when the road surface is wet. Change the tyre as soon as
possible or remount it with the correct direction of rotation.

ised speed above 240 km/h (149 mph). 
Snow chains
When using snow chains, applicable local legislation and maximum permit-
ted speed limits must be observed.
In winter weather, snow chains not only help to improve grip but also im-
prove the braking capacity.
The fitting of chains is permitted only on front wheels and only with the fol-
lowing combinations of wheel trims and tyres :
