Advice
drawing attention to your vehicle. This meth-
od must comply with traffic legislation. WARNING
A faulty vehicle in traffic represents a risk of
accident for the driver and for other road
users.
● Stop the vehicle safely as soon as possible.
Park the vehicle a safe distance from sur-
rounding traffic to lock all the doors in case of
an emergency. Turn on the hazard warning
lights to warn other road users.
● Never leave children or disabled people
alone in the vehicle if the doors are to be
locked. In case of an emergency, passengers
will be trapped inside the vehicle. Individuals
locked in the vehicle can be exposed to very
high or very low temperatures. WARNING
The components of the exhaust system reach
very high temperatures. This could cause a
fire and considerable damage.
● Always park your vehicle so that no part of
the exhaust system can come in contact with
flammable materials (such as dried grass or
fuel). Note
● The vehicle battery will discharge and run
down if the hazard warning lights remain on
for too long (even with the ignition turned
off). ●
For some vehicles, the brake lights will
blink when braking suddenly at speeds of ap-
proximately 80 km/h (50 mph) to alert vehi-
cles to the rear. If braking continues, the haz-
ard warning lights system will automatically
be turned on at a speed of less than approxi-
mately 10 km/h (6 mph). The brake lights re-
main lit. Upon accelerating, the hazard warn-
ing lights will be automatically turned off. Vehicle tool kit*
Introduction When securing the vehicle in case of a break-
down, please note the legal requirements for
each country.

Advice
Changing a wheel Introduction Some vehicle versions and models do not
have a factory-fitted jack or box spanner. In
this case, we recommend consulting a Speci-
alised workshop to change the wheel.
You should only change the wheels yourself if
the vehicle is parked in a safe place, you are
familiar with the procedure and safety stand-
ards and you have all the necessary tools!
Otherwise, you should seek professional as-
sistance.
WARNING
Changing a wheel can be dangerous, espe-
cially on the hard shoulder. Please observe
the following rules to minimise the risk of in-
jury:
● Stop the vehicle safely as soon as possible.
Park at a safe distance from surrounding traf-
fic to change a wheel.
● When changing a wheel, keep all passen-
gers, and particularly children, a safe dis-
tance away from the work area.
● Turn on the hazard warning lights to warn
other road users.
● Ensure the ground on which you park is flat
and solid. If necessary, support the jack on a
wide solid base. ●
If you are changing a wheel yourself, you
should be familiar with the required proce-
dure. Otherwise, you should seek professio-
nal assistance.
● Only use suitable tools that are not dam-
aged when changing a wheel.
● Always stop the engine, apply the hand-
brake lever firmly and place the selector lever
in position P, or engage a gear for a manual
gearbox to reduce the risk of the vehicle mov-
ing accidentally.
● Have the tightening torque of the wheel
bolts checked as soon as possible with a reli-
able torque wrench. WARNING
If the wheel trims are not appropriate or not
fitted correctly, they could cause major acci-
dents or damage.
● Incorrectly mounted wheel trims may come
off while driving and endanger other road
users.
● Damaged trims must never be mounted on
the wheels.
● Always ensure that the brake ventilation
and cooling is not cut off or blocked. This is
also valid if hubcaps are fitted later. If there
is not enough air, you may require signifi-
cantly longer braking distances. CAUTION
Remove and remount wheel trims taking care
to avoid damage to the vehicle. Hubcaps
Fig. 124
Remove the hubcap of the steel
wheel trim In order to access the wheel bolts, first re-
move the hubcap.
Removing and fitting the hubcap
● To remove , take the vehicle tool kit wire
hook and att
ach it to the edge of the wheel
trim ››› Fig. 124
.
● Remove the trim by pulling it in the direc-
tion of the arrow.
● To replace the hubcap , press the hubcap
against the trim until it clicks into place.

tion sho wn b
y the arrow.
Fitting hubcaps
Press the hubcap against the wheel so that
the space for the valve fits over the tyre valve.
Make sure that the hubcap is correctly fitted
all the way around the wheel. If you are using an anti-theft wheel lock, screw it in the oppo-
site position to the valve.
Wheel bolt caps Fig. 126
Removing the wheel bolt caps Removal
– Fit the plastic clip (vehicle tools
››› page 172 ) over the cap until it clicks into

Loosening anti-theft wheel bolts
For wheels with full hubcap, the anti-theft
wheel lock must be threaded into position
››› Fig. 128 2 before mounting the hubcap.
Otherwise it will not be possible to mount the
entire hubcap.
● Take the adapter for anti-theft wheel bolts
out of the vehicle tool kit.
● Insert the adapter onto the wheel bolt
››› Fig. 128 . Push it on as far as it will go.
● Fit the wheel

brace onto the adapter as far
as possible.
● Hold the wheel brace at the end and rotate
the bolt approximately one turn anticlockwise

› . Important information about wheel bolts
The wheel rims and bolts have been de-
signed to be fitted to factory options. If differ-
ent rims are fitted, the correct wheel bolts
with the right length and correctly shaped
bolt heads must be used. This ensures that
wheels are fitted securely and that the brake
system functions correctly.
In some circumstances, wheel bolts from the
same model vehicle should not be used.
Wheel bolt tightening torque
The prescribed tightening torque for wheel
bolts for steel and alloy wheels is
110 Nm
.
Hav e the tight

ening torque of the wheel bolts
checked as soon as possible with a reliable
torque wrench.
If wheel bolts are rusty and it is difficult to
tighten them, the threads should be replaced
and cleaned before checking the tightening
tor

que.
Never grease or lubricate wheel bolts or the
wheel hub threads. Although they have been
tightened to the prescribed torque, they
could come loose while driving. WARNING
If the wheel bolts are not fitted correctly they
could be released while driving leading to
loss of vehicle control and serious damage. ●
Only use wheel bolts which correspond to
the wheel rims in question.
● Never use different wheel bolts.
● The bolts and threads should be clean, free
of oil and grease and easy to thread.
● To loosen and tighten the wheel bolts, al-
ways use the wheel brace supplied with the
vehicle.
● Loosen the wheel bolts only about one turn
before raising the vehicle with the jack.
● Never grease or lubricate wheel bolts or the
wheel hub threads. Although they have been
tightened to the prescribed torque, they
could come loose while driving.
● Never loosen the bolted joints of wheel
rims with bolted ring trims.
● If the wheel bolts are not tightened to the
correct torque, they may come loose while
driving, and the bolts and rims may come
out. If the tightening torque is too high, the
wheel bolts and threads can be damaged. 176

If the vehicle is not correctly raised, it could
fall off the jack causing serious injury. Please
observe the following rules to minimise the
risk of injury:
● You should only use a jack approved by
SEAT for your vehicle. Other jacks, even those
approved for other SEAT models, might slip
out of place.
● The ground should be firm and flat. If the
ground is sloped or soft then the vehicle
could slip and fall off the jack. If necessary,
support the jack on a wide solid base.
● If the ground is slippery, such as tiles,
place a non-slip surface (a floor mat, for in-
stance) beneath the jack to avoid slipping.
● Only fit the jack at the prescribed jacking
points. The claw of the jack should grip the
reinforcement nerve on the underbody
››› Fig. 130.
● You shou

ld never place a body limb such as
an arm or leg under a raised vehicle that is
solely supported by the jack.
● If you have to work underneath the vehicle,
you must use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!.
● Never raise the vehicle if it is tilting to one
side or the engine is running.
● Never start the engine when the vehicle is
raised. The vehicle may come loose from the
jack due to the engine vibrations. 177

Tyre repair
TMS (Tyre Mobility System)* The Anti-puncture kit* (Tyre Mobility System)
will reliably seal punctures caused by the
penetration of a foreign body of up to about
4 mm
in diameter.
Do not remove foreign ob-
j

ects, e.g. screws or nails, from the tyre.
After inserting the sealant residue in the tyre,
you must again check the tyre pressure about
10 minutes after starting the engine.
You should only use the tire mobility set if
the vehicle is parked in a safe place, you are
familiar with the procedure and you have the
necessary tire mobility set! Otherwise, you
should seek professional assistance.
The tyre sealant must not be used in the
following cases: ● If the wheel rim has been damaged.

Emergencies
WARNING
When inflating the wheel, the air compressor
and the inflator tube may become hot.
● Protect hands and skin from hot parts.
● Do not place the hot flexible inflator tube or
hot air compressor on flammable material.
● Allow them to cool before storing the de-
vice.
● If it is not possible to inflate the tyre to at
least 2.0 bars (29 psi / 200 kPa), the tyre is
too badly damaged. The sealant is not in a
good condition to seal the tyre. Do not con-
tinue driving. Seek specialist assistance. CAUTION
Switch off the air compressor after a maxi-
mum of 8 operational minutes to avoid over-
heating! Before switching on the air compres-
sor again, let it cool for several minutes. Check after 10 minutes of driving

● Car
efully resume your journey until you
reach the nearest specialised workshop with-
out exceeding 80 km/h (50 mph).
● Have the damaged tyre replaced. WARNING
Driving with an unsealed tyre is dangerous
and can cause accidents and serious injury.
● Do not continue driving if the tyre pressure
is 1.3 bar (19 psi / 130 kPa) and lower.
● Seek specialist assistance. Starting assistance
Introduction If the engine fails to start because of a dis-
charged battery, the battery of another vehi-
cle can be used to start the engine. Before
starting, check the magic eye on the battery
››› page 154 .
F or s

tarting assistance, jump lead cables con-
forming to the standard DIN 72553 are re-
quired (see the cable manufacturer instruc-
tions). The cable section in vehicles with pet-
rol engine must be at least 25 mm 2
. WARNING
Incorrect use of jump leads and incorrectly
jump starting could cause the battery to ex-
plode resulting in serious injury. Please ob-
serve the following rules to minimise the risk
of a battery explosion:
● The battery providing current must have
the same voltage (12V) and approximately
the same capacity (see markings on battery)
as the flat battery.
● Never charge a frozen or recently thawed
battery. A flat battery can also freeze at tem-
peratures close to 0 °C (+32 °F).
● If a battery is frozen and/or has been frozen
then it must be replaced.
● A highly explosive mixture of gases is re-
leased when the battery is being charged. Al-
ways keep lit cigarettes, flames, sparks and
fire far from the battery. Never use a mobile
telephone when connecting and removing the
jump leads.
● Charge the battery only in well ventilated
areas given that when the battery is charged
by outside assistance, it creates a mix of
highly explosive gases.
● Jump leads should never enter into contact
with moving parts in the engine compart-
ment.
● Never switch the positive and negative
poles or connect the jump leads incorrectly.
● Note the instruction manual provided by
the manufacturer of the jump leads. » 181

Emergencies
Connect the battery clamps so they have
good metal-to-metal contact with the battery
terminals.
If the engine fails to start, switch off the start-
er after about 10 seconds and try again after
about 1 minute. WARNING
● Please note the safety warnings referring to
working in the engine compartment
››› page 143.
● The b att
ery providing assistance must have
the same voltage as the flat battery (12V) and
approximately the same capacity (see imprint
on battery). Failure to comply could result in
an explosion.
● Never use jump leads when one of the bat-
teries is frozen. Danger of explosion! Even af-
ter the battery has thawed, battery acid could
leak and cause chemical burns. If a battery
freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes
away from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufacturer of the jump leads.
● Do not connect the negative cable from the
other vehicle directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion. ●
Do not attach the negative cable from the
other vehicle to parts of the fuel system or to
the brake line.
● The non-insulated parts of the battery
clamps must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot come into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult in chemical burns. Note
The vehicles must not touch each other, oth-
erwise electricity could flow as soon as the
positive terminals are connected. Towing and tow starting
Introduction When towing or tow starting, respect the le-
gal requirements.
For technical reasons, it is not possible to
tow a vehicle if the battery is flat. WARNING
A vehicle with a flat battery should never be
towed.
● Never remove the key from the ignition
lock. Otherwise, the steering wheel lock
could suddenly lock. The vehicle would not
be controlled and a serious accident could
ensue. WARNING
When towing the vehicle, the handling and
braking efficiency change considerably.
Please observe the following instructions to
minimise the risk of serious accidents and in-
jury:
● As the driver of the vehicle being towed:
– The brake must be depressed must hard-
er as the brake servo does not operate.
Always remain aware to avoid collision
with the towing vehicle.
– More strength is required at the steering
wheel as the power steering does not op-
erate when the engine is switched off.
● As the driver of the towing vehicle:
– Accelerate gently and carefully.
– Avoid sudden braking and manoeuvres.
– Brake well in advance than usual and
brake gently.

CAUTION
● Carefully fit and remove the towline anchor-
age and its cover to avoid damage to the ve-
hicle (e.g. paintwork).
● When towing, fuel could enter the catalytic
converter and cause damage! Note
Fitting a towline anchorage to the rear bump-
er is not possible. The vehicle is not suitable
for towing other vehicles. Instructions for tow starting
In general, the vehicle should not be started
by towing. Jump-starting is much more pref-
erable
›
› ›
page 181.
For technical reasons, the following vehicles
can
not be tow started:
● Vehicles with an automatic gearbox.
● If the vehicle battery is flat, it is possible
that the engine control unit does not operate
correctly.
However, if your vehicle must absolutely be
tow-started (manual gearbox):
● Put it into second or third gear.
● Keep the clutch pressed down. ●
Switch on the ignition and the hazard warn-
ing lights.
● Release the clutch when both vehicles are
moving.
● As soon as the engine starts, press the
clutch and move the gear lever into neutral.
This helps to prevent a collision with the tow-
ing vehicle. CAUTION
When tow-starting, fuel could enter the cata-
lytic converter and damage it. Notes on towing
Tow rope or tow bar
When towing, the tow bar is the safest and
vehicle friendly way. You should only use a
tow rope if you do not have a tow bar.
A tow rope should be slightly elastic to avoid
damage to both vehicles. It is advisable to
use a tow rope made of synthetic fibre or sim-
ilarly elastic material.
Only secure the tow rope or tow bar to the
towline anchorage or specially designed fit-
ting.
Towing vehicles with an automatic gearbox
Note the following for a towed vehicle:●
Make sure the gear selector lever is in the N
position.
● Do not drive faster than 50 km/h (30 mph)
when towing a vehicle.
● Do not tow further than 50 km (30 miles).
● If a breakdown truck is used, the vehicle
must be towed with the front wheels raised.
Situations in which the vehicle should not be
towed
In the following cases, the vehicle should not
be towed but transported on a trailer or spe-
cial vehicle:
● If the vehicle gearbox does not contain lu-
bricant due to a fault.
● If the battery is flat and the steering cannot
be unlocked as a result, the electronic steer-
ing lock and electronic parking brake cannot
be disengaged.
● If the vehicle to be towed has an automatic
gearbox and the distance to be covered is
greater than 50 km (30 miles). Note
The vehicle can only be towed if the steering
lock electronic gearbox lock is deactivated. If
the vehicle has no power supply or there is
an electric system fault, the engine must be
started using jump leads to deactivate the
steering column electronic gearbox lock. 184
