2010 Seat Leon 5D towing

Intelligent technology
188Electronic Stability Programme (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 vehicle. If the desired course is not being
maintained (for instance, if the vehicle is starting to skid), then the ESP
compensates 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.
Steering manoeuvre recommendations
This is a complementary safety function included in the ESP This function aids
the driver to better stabilize the vehicle in a critical situation. For example, in
case of sudden braking surface with varied adherence, the vehicle will tend
to destabilise its trajectory to the right or to the left. In this case the ESP
recognizes the situation and helps the driver with a counter steering
manoeuvre from the power steering.
This function simply provides the driver with a recommended manoeuvre in
critical situations.
The vehicle does not steer itself with this function, the driver has full control
of the vehicle at all times.
WARNING
•It must be remembered that ESP cannot 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, as 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 186.Electronic 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 84.
At speeds of up to approximately 80 km/h, it is able to balance out differ-
ences in the speed of the driven wheels 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.

Technical Specifications
Trailer towingInstructions to followYour vehicle may be used to tow a trailer when fitted with the correct equip-
ment.
If the vehicle is supplied with a factory-fitted towing bracket it will already
have the necessary technical modifications and meet the statutory require-
ments for towing a trailer. For the after-market fitting of a trailer towing
bracket see ⇒page 201.
Connectors
Your vehicle is fitted with a 12-pin connector for the electrical connection
between the trailer and the vehicle.
If the trailer has a 7-pin plug you will need to use an adapter cable. This is
available in any SEAT dealer.
Trailer weight / drawbar load
Never exceed the authorised trailer weight. If you do not load the trailer up to
the maximum permitted trailer weight, you can then climb correspondingly
steeper slopes.
The maximum trailer weights listed are only applicable for altitudes up to
1000m above sea level. With increasing altitude the engine power and there-
fore the vehicle’s climbing ability are impaired because of the reduced air
density. The maximum trailer weight has to be reduced accordingly. The
weight of the vehicle and trailer combination must be reduced by 10% for
every 1000 m of height. The gross combination weight is the actual weight of
the laden vehicle plus the actual weight of the laden trailer. When possible,
operate the trailer with the maximum permitted drawbar load on th e ba ll jo int
of the towing bracket, but do not exceed the specified limit. The figures for
trailer weights and drawbar loads that are given on the data
plate of the towing bracket are for certification purposes only. The correct
figures for your specific model, which may be lower than these figures for the
towing bracket, are given in the vehicle documents or in ⇒Section “Tech-
nical Data”.
Distributing the load
Distribute loads in the trailer so that heavy objects are as near to the axle as
possible. Loads carried in the trailer must be secured to prevent them
moving.
Tyre pressure
Set tyre pressure to the maximum permissible pressure shown on the sticker
on the inside of the fuel tank flap. Set the tyre pressure of the trailer tyres in
accordance with the trailer manufacturer’s recommendations.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard mirrors. If this is not the case, you should have additional mirrors
fitted. Both exterior mirrors should be mounted on hinged extension
brackets. Adjust the mirrors to give sufficient vision to the rear.
WARNING
Never transport people in a trailer. This could result in fatal accidents.
Note
•Towing a trailer places additional demands on the vehicle. We recom-
mend additional services between the normal inspection intervals if the
vehicle is used frequently for towing a trailer.

200•Find out whether special regulations apply to towing a trailer in your
country.Ball coupling of towing bracket*Depending on the model version, the spherical head on the trailer hook may
be found in the tool box.
The ball coupling is provided with instructions on fitting and removing the
ball coupling of the towing bracket.
WARNING
The towing bracket ball coupling must be stored securely in the luggage
compartment to prevent them being flung through the vehicle and causing
injury.
Note
•By law, the ball coupling must be re moved if a trailer is not being towed
and it obscures the number plate.Driving tipsDriving with a trailer always requires extra care.Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slowly to allow
for the unbalanced weight distribution. Speed
The stability of the vehicle and trailer is reduced with increasing speed. For
this reason, it is advisable not to drive at the maximum permissible speed in
an unfavourable road, weather or wind conditions. This applies especially
when driving downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of
snaking . Never try to stop the “snaking” by increasing speed.
Always brake in due course. If the trailer has an overrun brake, apply the
brakes gently at first and then, firmly. This will prevent the jerking that can be
caused by the trailer wheels locking. Select a low gear in due course before
going down a steep downhill. This enables you to use the engine braking to
slow down the vehicle.
Reheating
At very high temperatures and during prolonged slopes, driving in a low gear
and high engine speed, always monitor the coolant temperature gauge

Fitting a towing bracket•Driving with a trailer involves an extra effort for the vehicle. Therefore,
before fitting a towing bracket, please contact an Authorised Service Centre
to check whether your cooling system needs modification.•The legal requirements in your country must be observed (e.g. the fitting
of a separate warning lamp).•Certain vehicle components, e.g. the rear bumper, must be removed and
reinstalled. The towing bracket securing bolts must be tightened using a
torque wrench, and a power socket must be connected to the vehicle’s elec-
trical system. This requires specialised knowledge and tools.•Figures in the illustration show the elevation value and the attachment
points which must be considered if you are retrofitting a towing bracket.WARNING
The towing brackets should be fitted at a specialised workshop.
•If the towing bracket is incorrectly installed, there is serious danger of
accident.•For your own safety, please observe the instructions provided by the
manufacturer of the towing bracket.Caution
•If the power socket is incorrectly installed, this could cause damage to the
vehicle’s electrical system.Note
For the sports model (FR, Cupra...), fitting of a trailer bracket is not recom-
mended due to the design of the bumpers.

Tyre repair kit*
The tyre repair kit (for vehicles not including a spare wheel) is
stored under the floor panel in the luggage compartment.Your vehicle is equipped with the Tyre Mobility System “Tyre repair kit”.
The tyre repair kit consists of a container with sealing compound to repair the
puncture and a compressor to generate the required tyre pressure. The kit will
reliably seal punctures up to a size of about 4 mm caused by the penetration
of a foreign body into the tyre.
Note
•Seek professional assistance if the repair of a tyre puncture is not
possible with the sealing compound.Changing a wheelPreparation work
What you must do before changing a wheel.– If you have a flat tyre or puncture, park the vehicle as far away from the flow of traffic as possible. Choose a location that is as
level as possible.
– All passengers should leave the vehicle. They should wait in a safe area (for instance behind the roadside crash barrier).
– Switch off the engine. Switch on the hazard warning lights.
–Apply the handbrake firmly. – Engage the
first gear, or put the selector lever to position P for
those vehicles with an automatic gearbox.
– If you are towing a trailer, unhitch it from your vehicle.
– Take the vehicle tools and the spare wheel out of the luggage
compartment.
WARNING
Put the hazard warning lights on and place the warning triangle in position.
This is for your own safety and also warns other road users.
Caution
If you have to change the wheel on a gradient, block the wheel opposite the
wheel being changed by placing a stone or similar object under it to prevent
the vehicle from rolling away.
Note
Please observe legal requirements when doing so.Changing a wheelChange the wheel as described below
–Pull off the hub cap. See ⇒ page 248, fig. 155 .
– Slacken the wheel bolts.
– Raise the car with the jack at the corresponding point.

270Towing and tow-startingTo w - s t a r t i n g
The use of jump leads is preferable to tow-starting.We recommend that you do not tow-start your vehicle. Jump-starting
is preferable ⇒ page 267.
However, if your vehicle has to be tow-started:
– Engage the 2nd or the 3rd gear.
– Keep the clutch pressed down.
– Switch the ignition on.
– Once both vehicles are moving, release the clutch.
– As soon as the engine starts, press the clutch and move the gear lever into neutral. This helps to prevent driving into the towing
vehicle.
WARNING
The risk of accidents is high when tow-starting. The vehicle being towed
can easily collide with the towing vehicle.
Caution
When tow-starting, fuel could enter the catalytic converter and damage it.
CommentsPlease observe the following points if you use a tow-rope:
Notes for the driver of the towing vehicle
– Drive slowly at first until the tow-rope is taut. Then accelerate gradually.
– Begin and change gears cautiously. If you are driving an auto- matic vehicle, accelerate gently.
– Remember that the brake servo and power steering are not working in the vehicle you are towing. Brake sooner than normal
and pressing the pedal gently.
Notes for the driver of the towed vehicle
– Ensure that the tow-rope remains taut at all times when towing.Tow-rope or tow-bar
It is easier and safer to tow a vehicle with a tow-bar. You should only use a
tow-rope if you do not have a tow-bar.
A tow-rope should be slightly elastic to reduce the loading on both vehicles.
It is advisable to use a tow-rope made of synthetic fibre or similarly elastic
material.
Attach the tow-rope or the tow-bar only to the towing eyes provided or a
towing bracket.
Driving style
Towing requires some experience, especially when using a tow-rope. Both
drivers should be familiar with the technique required for towing. Inexperi-
enced drivers should not attempt to tow.
