Practical tipsIntelligent technologyBrakesBrake servoThe brake servo amplifies the pressure you apply to the brake pedal. It works
only when the engine is running .
If the brake servo is not functioning due to a malfunction, or if the vehicle has
to be towed, you will have to press the brake pedal considerably harder to
make up for the lack of servo assistance.
WARNING
The braking distance can also be affected by external factors.•
Never let the vehicle coast with the engine switched off. Failure to do so
could result in an accident. The braking distance is increased considerably
as the brake servo does not function.
•
If the brake servo is not working, for example when the vehicle is being
towed, you will have to press the brake pedal considerably harder than
normal.
Brake Assist System (BAS)*
The Brake Assist System function is only included in vehicles
with ESP.In an emergency, most drivers brake in time, but not with maximum force.
This results in unnecessarily long braking distances.
This is when the brake assist system comes into action. When pressing the
brake pedal rapidly, the assistant interprets it as an emergency. It then very
quickly builds up the full brake pressure so that the ABS can be activated
more quickly and efficiently, thus reducing the braking distance.
Do not reduce the pressure on the br ake pedal. The brake assist system
switches off automatically as soon as you release the brake.
Warning lights automatic lighting
In the event of sharp or emergency braking, the warning hazard lights will
switch on automatically.
WARNING
•
The risk of accident is higher if yo u drive too fast, if you do not keep
your distance to the vehicle in front, and when the road surface is slippery
or wet. The increased accident risk cannot be reduced by the brake assist
system.
•
The brake assist system cannot defy the laws of physics. Slippery and
wet roads are dangerous even with the brake assist system! Therefore, it is
essential that you adjust your speed to suit the road and traffic conditions.

150Do not let the extra safety features tempt you into taking any risks when
driving.Anti-lock brake system and traction control
ABSAnti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking
during braking.The anti-lock brake system (ABS) is an important part of the vehicle?s active
safety system.
How the ABS works
If one of the wheels is turns too slowly in relation to the road speed, and is
close to locking, the system will reduce the braking pressure for this wheel.
The driver is made aware of this control process by a pulsating of the brake
pedal and audible noise. This is a deliberate warning to the driver that one or
more of the wheels is tending to lock and the ABS control function has inter-
vened. In this situation it is important to keep the brake pedal fully depressed
so the ABS can regulate the brake application. Do not “pump”.
If you brake hard on a slippery road surface, the best possible control is
retained as the wheels do not lock.
However, ABS will not necessarily guarantee shorter braking distances in all
conditions. The braking distance could even be longer if you brake on gravel
or on fresh snow covering a slippery surface.
WARNING
•
The anti-lock brake system cannot defy the laws of physics. Slippery
and wet roads are dangerous even with ABS! If you notice that the ABS is
working (to counteract locked wheels under braking), you should reduce
speed immediately to suit the road and traffic conditions. Do not let the
extra safety features tempt you into taking any risks when driving.
•
The effectiveness of ABS is also determined by the tyres fitted
⇒ page 197.
•
If the running gear or brakes are mo dified, the effectiveness of the ABS
could be severely limited.
Traction control system (TCS)*
The traction control system prevents the drive wheels from
spinning when the car is acce lerating. The system always
includes ABSDescription and operation of the traction control system during acceleration
(TCS)
TCS reduces engine power to help prevent the drive wheels of front-wheel
drive vehicles losing traction during acceleration. The system works in the
entire speed range in conjunction with ABS. If a malfunction should occur in
the ABS, the TCS will also be out of action.
TCS helps the vehicle to start moving, accelerate and climb a gradient in slip-
pery conditions where this may otherwise be difficult or even impossible.
The TCS is switched on automatically when the engine is started. If necessary,
it may be turned on or off by briefly pushing the ESP button on the centre
console.
When the TCS is switched off, the warning lamp flashes slowly. The TCS
should normally be left switched on at all times. Only in exceptional circum-

stances, when the slipping of the wheels is required, they can be discon-
nected with the ESP button, for example.
•
With compact temporary spare wheel.
•
When using the snow chains.
•
When driving in deep snow or on loose surfaces
•
When the vehicle is bogged-down, to free it by “rocking.”
The TCS should be switched on again afterwards as soon as possible.
WARNING
•
It must be remembered that TCS cann ot defy the laws of physics. This
should be kept in mind, particular ly on slippery and wet roads and when
towing a trailer.
•
Always adapt your driving style to suit the condition of the roads and
the traffic situation. Do not let the extra safety afforded by TCS tempt you
into taking any risks when driving, this can cause accidents.Caution
•
In order to ensure that TCS function correctly, all four wheels must be
fitted with the same tyres. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.
•
Modifications to the vehicle (e.g. to the engine, the brake system, running
gear or any components affecting the wh eels and tyres) could affect the effi-
ciency of the ABS and TCS.
Electronic stabilisation programme (ESP)*General notes
The electronic stabilisation programme increases the
vehicle?s stability on the road.The electronic stabilisation programme helps to reduce the danger of skid-
ding.
The electronic stabilisation programme (ESP) consists of ABS, EDL and TCS.
Electronic Stabilising Program (ESP)*
ESP reduces the danger of skidding by braking the wheels individually.
The system uses the steering wheel angle and road speed to calculate the
changes of direction desired by the driver, and constantly compares them
with the actual behaviour of the vehi cle. If the desired course is not being
maintained (for instance, if the car is starting to skid), then the ESP compen-
sates automatically by braking the appropriate wheel.
The forces acting on the braked wheel bring the vehicle back to a stable
condition. If the vehicle tends to oversteer, the system will act on the front
wheel on the outside of the turn.
WARNING
•
It must be remembered that ESP cann ot defy the laws of physics. This
should be kept in mind, particularly on slippery and wet roads and when
towing a trailer.
•
Always adapt your driving style to suit the condition of the roads and
the traffic situation. Do not let the extra safety afforded by ESP tempt you
into taking any risks when driving, this can cause accidents.

Caution•
In order to ensure that ESP functions correctly, all four wheels must be
fitted with the same tyres. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.
•
Modifications to the vehicle (e.g. to the engine, the brake system, running
gear or any components affecting the wheels and tyres) could affect the effi-
ciency of the ABS, EDL, ESP and TCS.
Anti-lock brake system (ABS)The anti-lock brake system prevents the wheels locking during braking
⇒ page 150Electronic differential lock (EDL)*
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.EDL helps the vehicle to start moving, accelerate and climb a gradient in slip-
pery conditions where this may otherwise be difficult or even impossible.
The system will control the revolutions of the drive wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒page 61.
At speeds of up to approximately 80 km/h, it is able to balance out differ-
ences in the speed of the driven wheel s of approximately 100 rpm caused by
a slippery road surface on one side of the vehicle. It does this by braking the
wheel which has lost traction and distributing more driving force to the other
driven wheel via the differential. To prevent the disc brake of the braking wheel from overheating, the EDL cuts
out automatically if subjected to excessive loads. The vehicle will continue to
function normally without EDL. For this
reason, the driver is not informed that
the EDL has been switched off.
The EDL will switch on again automatically when the brake has cooled down.
WARNING
•
When accelerating on a slippery surface, for example on ice and snow,
press the accelerator carefully. Despite EDL, the driven wheels may start to
spin. This could impair the vehicle?s stability.
•
Always adapt your driving style to su it road conditions and the traffic
situation. Do not let the extra safety afforded by EDL tempt you into taking
any risks when driving, this can cause accidents.Caution
Modifications to the vehi cle (e.g. to the engine, the brake system, running
gear or any components affecting the wheels and tyres) could affect the effi-
ciency of the EDL. ⇒page 173The traction control system (TCS)The traction control system prevents the drive wheels from spinning when the

Checking and refilling levels
182•
Avoid causing short-circuits in the electrical system, particularly at the
points where the jump leads are attached ⇒page 228. The battery could
explode.
•
Never touch the radiator fan. It is temperature controlled and could
start automatically, even when the engine has been switched off and the
key removed from the ignition!
•
Do not unscrew the cap on the expansion tank when the engine is hot.
If the coolant is hot, the cooling system will be pressurised!
•
Protect face, hands and arms by covering the cap with a large, thick
cloth to protect against escaping coolant and steam.
•
Always make sure you have not left any objects, such as cleaning cloths
and tools, in the engine compartment.
•
If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, there is a risk of accident!. A
hydraulic jack is insufficient for securing the vehicle and there is a risk of
injury.
•
If any work has to be performed when the engine is started or with the
engine running, there is an additional, potentially fatal, safety risk from the
rotating parts, such as the drive belts, alternator, radiator fan, etc., and
from the high-voltage ignition syst em. You should also observe the
following points:
−Never touch the electrical wiri ng of the ignition system.
− Ensure that jewellery, loose clothing and long hair do not get
trapped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
− Always think carefully about pressing the accelerator if a gear is
engaged in either an automatic or manual gearbox. The vehicle could
move, even if the handbrake is applied. Danger of death.
•
If work has to be carried out on the fuel system or on electrical compo-
nents, you must observe the following safety notes in addition to the above
warnings:
−Always disconnect the battery. The vehicle must be unlocked when
this is done, otherwise the alarm will be triggered.
− Do not smoke.
− Never work near naked flames.
− Always have a fire extinguisher on hand.Caution
When changing or topping up service fluids, make absolutely certain that you
fill the fluids into the correct reservoirs. Failure to observe this point will result
in serious malfunctions and engine damage!
For the sake of the environment
Service fluids leaks are harmful to th e environment. For this reason you
should make regular checks on the ground underneath your vehicle. If you
find spots of oil or other fluids, have your vehicle inspected in a qualified
workshop.

Checking and refilling levels
194However, if the level goes down noticeably in a short time, or drops below the
“MIN” mark, there may be a leak in the brake system. A display on the instru-
ment panel will warn you if the brake fluid level is too low ⇒page 57.
WARNING
Before opening the bonnet to check the brake fluid level, read and observe
the warnings ⇒page 181.Changing the brake fluid
The Maintenance Program indicates the brake fluid change
intervals.We recommend that you have the brake fluid changed by an Authorised
Service Centre.
Before opening the bonnet, please read and follow the warnings ⇒ in
“Safety instructions on working in the engine compartment” on page 181 in
section “Safety notes for workin g in the engine compartment”.
Brake fluid absorbs moisture. In the cour se of time, it will absorb water from
the ambient air. If the water content in the brake fluid is too high, the brake
system could corrode. This also considerably reduces the boiling point of the
brake fluid. Heavy use of the brakes may then cause a vapour lock which
could impair the braking effect.
It is important that you use only brake fluid compliant with the US standard
FMVSS 116 DOT 4. We recommend the use of Genuine SEAT brake fluid.
WARNING
Brake fluid is poisonous. Old brake fluid impairs the braking effect.
•
Before opening the bonnet to check the brake fluid level, read and
observe the warnings ⇒page 181.
•
Brake fluid should be stored in the closed original container in a safe
place out of reach of children. There is a toxic risk.
•
Complete the brake fluid change according to the Maintenance
Program. Heavy use of the brakes may cause a vapour lock if the brake fluid
is left in the system for too long. Th is would seriously affect the efficiency
of the brakes and the safety of the vehicle. This may cause an accident.Caution
Brake fluid could damage the paintwork. Wipe off any brake fluid from the
paintwork immediately.
For the sake of the environment
Brake fluid must be drained and disposed of in the proper manner observing
environmental regulations.
