Tyre monitoring indicator
Fig. 102 Glove compart-
ment: tyre control switch
The tyre monitor indicator compares wheel revolutions and, with this infor-
mation, the tread of each wheel using the ABS sensors. If the tread of one or
more wheels is changed, the tyre monitoring indicator will indicate as such
on the instrument panel.
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
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. 102.
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 266.
Note
● The tyre monitoring indicator does not function when there is a fault in
the ESC or ABS ⇒ page 183.
● An erroneous indication may be given when snow chains are in use be-
cause the chains increase the tread of the wheel. 

Electronic Stability Control (ESC)
Description
EI ESC helps to improve safety. It reduces the tendency to skid and improves
the stability and roadholding of the vehicle. EI ESC detects critical handling
situations, such as vehicle understeer or oversteer, or wheelspin on the
driving wheels. It stabilises the vehicle by braking individual wheels or by
reducing the engine torque. The warning lamp will flash on the instrument
panel when the ESC is intervening .
ESC includes the Anti-lock brake system (ABS), the brake assist system, the
traction control system (ASR), electronic differential lock (EDL), electronic
self-locking*, selective torque control* and tractor-trailer sway mitigation*.
ESC also helps stabilise the vehicle by changing the torque.
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under braking until the vehicle
has reached a virtual standstill. You can continue to steer the vehicle even
when the brakes are on full. Keep your foot on the brake pedal and do not
pump the brakes. You will feel the brake pedal pulsate while the ABS is
working.
Brake assist system
The brake assist system can reduce the required braking distance. The brak-
ing force is automatically boosted if you press the brake pedal quickly in an
emergency. You must keep pressing the brake pedal until the danger has
passed. Traction control system (ASR)
In the event of wheelspin, the traction control system reduces the engine
torque to match the amount of grip available. This helps the car to start
moving, accelerate or climb a gradient.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes the spinning wheel and directs
the power to the other driven wheel. This function is available up to a speed
of around 100 km/h, 62 mph).
To prevent the disc brake of the braked wheel from overheating, the EDL
cuts out automatically if subjected to excessive loads. The vehicle can still
be driven. The EDL will switch on again automatically when the brake has
cooled down.
Tractor-trailer sway mitigation*
If the vehicle is pulling a trailer, it will control the following: Tractor-trailers
tend to sway. When the swaying of the trailer is felt by the vehicle and de-
tected by the ESC, it will automatically brake the towing vehicle within the
limits of the system and mitigate the sway. Tractor-trailer sway mitigation is
not available in all countries.
Electronic self-locking*/Selective torque control*
When driving around bends, an electronic self-locking intervenes. The front
wheel on the inside of the curve, or the two inside wheels, respectively, are
selectively braked as required. This minimises the traction of the front
wheels, allowing you to take bends with greater precision and neutrality. In
certain circumstances, where roads are wet or snow-covered, the respective
system may not intervene.

Checking and refilling levels
Brake fluid
Fig. 111 Engine com-
partment: brake fluid res-
ervoir, lid
Checking the brake fluid level
The brake fluid level must be between the MIN and MAX markings.
However, if the brake fluid level goes down noticeably in a short time, or
drops below the MIN mark, there may be a leak in the brake system. Seek
specialist assistance. A warning light on the instrument panel display moni-
tors the brake fluid level ⇒ page 69.
In right-hand drive vehicles the brake fluid reservoir is on the other side of
the engine compartment.
Changing brake fluid
The regular intervals at which the brake fluid should be replaced are listed
in the Service Plan. We recommend you have the brake fluid replaced at a
SEAT Official Service, during an Inspection Service.
WARNING
● Brake fluid should be stored in the closed original container in a safe
place out of reach of children. Risk of poisoning!
● If the brake fluid is left in the system for too long and the brakes are
subjected to heavy use, vapour bubbles may form in the brake system.
This would seriously affect the efficiency of the brakes and the safety of
the vehicle. This may cause an accident.
CAUTION
Brake fluid should not come into contact with the vehicle paintwork, as it is
abrasive. 
Battery General information
The battery is located in the engine compartment and is almost mainte-
nance-free. It is checked as part of the Inspection Service. Nevertheless,
check the terminals are clean and have the correct tightening torque, espe-
cially in summer and winter.
Disconnecting the battery
The battery should only be disconnected in exceptional cases. When the
battery is disconnected, some of the vehicles functions are "lost" ( ⇒ table
on page 218). These functions will require resetting after the battery is re-
connected.
Deactivate the anti-theft alarm* before you disconnect the battery Other-
wise the alarm will be triggered. 

Emergencies
Note
Do not use the compressor for longer than 6 minutes at a time, as it could
overheat. Once it has cooled down, the compressor may be used again. 
After changing a wheel
– Attach the "max. 80 km/h (50 mph)" adhesive label from the
tyre repair kit on the instrument panel, clearly within view of the
driver.
– Stop the vehicle after 10 minutes driving and check the tyre
pressure.
– If tyre pressure is less than 1.3 bar, the tyre is too badly dam-
aged. Do not carry on driving!
WARNING
After repairing a tyre please note the following points:
● Do not drive faster than 80 km/h (50 mph).
● Avoid heavy acceleration, hard braking and fast cornering.
● Vehicle handling could be impaired.
● If the tyre is very damaged, seek professional assistance.
For the sake of the environment
You can dispose of the used bottle of sealing compound at a SEAT Official
Service.
Note
After repairing a tyre, remember to purchase a new bottle of sealing com-
pound from a SEAT Official Service or a specialised workshop. 
Changing a wheel What to do first
