The P ark Assist syst
em cannot be switched
on if the factory-fitted towing bracket

trailer.
After changing a wheel
If, after changing a wheel, the vehicle stops
entering and exiting parking spaces correct-
ly, the circumference of the new wheel may
be different and the system may need to
adapt to it. The adaptation is automatic and
takes place during driving. Making turns slow-
ly and in both directions (20 km/h [12 mph])
for a few minutes may contribute to this
adaptation process ››› in Introduction on
page 283.

Reverse angle parking.
Forward angle parking.
Reverse parallel parking without driving

Forward parking in a parking bay without
driving past first.
Selecting a parking type after passing in

convenience functions, such as remote vehi-
cl e opening, may not be av
ailable under cer-
tain circumstances. These functions will be
restored when you switch on the ignition and
start the engine.
With the engine switched off
For example, if you listen to the sound system
with the engine switched off the battery will
run down.
If the energy consumption means there is a
risk that the engine will not start, a text will
appear in vehicles with a driver information
system*.
This driver indicator tells you that you must
start the engine so that the battery can re-
charge.
When the engine is running
Although the alternator generates electrical
power, the battery can still become dis-
charged while the vehicle is being driven. This
can occur when a lot of power is being con-
sumed but only a small amount supplied, es-
pecially if the battery is not fully charged ini-
tially.
To restore the necessary energy balance, the
system will then temporarily shut off the elec-
trical devices that are using a lot of power, or
reduce the current they are consuming. Heat-
ing systems in particular use a large amount
of electrical power. If you notice, for instance, that the seat heating* or the rear window
heater is not w
orking, they may have been
temporarily switched off or regulated to a
lower heat output. These systems will be
available again as soon as sufficient electri-
cal power is available.
You may also notice that the engine runs at a
slightly faster idling speed when necessary.
This is quite normal, and no cause for con-
cern. The increased idling speed allows the
alternator to meet the greater power require-
ment and charge the battery at the same
time. Wheels

General notes

Practical tips
Low profile tyres
L o
w profile tyres have a wider tread, a larger
wheel diameter and a lower sidewall height.
Therefore, its driving behaviour is more agile.
Low profile tyres may deteriorate more quick-
ly than standard tyres, for instance due to
strong knocks, potholes, manhole covers and
kerbs. Correct tyre pressure is very important
››› page 348.
To avoid damage to tyres and wheels, drive
with special care when driving on roads in
poor condition.
Visually check your wheels every 3000 km.
If the tyres or rims have received a heavy im-
pact or have been damaged, have a special-
ised workshop check whether or not it is nec-
essary to change the tyre.
Low profile tyres may deteriorate more quick-
ly than standard tyres.
Concealed damage
Damage to tyres and rims is often not readily
visible. If you notice unusual vibration or the
car pulling to one side, this may indicate
that one of the tyres is damaged. Reduce
speed immediately if there is any reason to
suspect that damage may have occurred. In-
spect the tyres for damage. If no external
damage is visible, drive slowly and carefully
to the nearest specialised workshop and
have the car inspected. Foreign objects inserted in the tyre

Wheels
New wheels and tyres It is best to have all wheels and tyres serviced
by a specialised w
orkshop
. There they have
the required knowledge, the special tools and
the corresponding spare parts.

Wheels
Driving style
F ast cornering, heavy accel
eration and hard
braking (squealing tyres) all increase tyre
wear.
Wheel balance
The wheels on new vehicles are balanced.
However, certain circumstances may lead to
imbalance (run-out), which is detected as vi-
brations in the steering wheel.
Unbalanced wheels should be rebalanced,
as they otherwise cause excessive wear on
steering, suspension and tyres. A wheel must
also be rebalanced when a new tyre is fitted
or if a tyre is repaired.
Incorrect wheel alignment
Incorrect running gear alignment causes ex-
cessive tyre wear, impairing the safety of the
vehicle. If you notice excessive tyre wear, you
should check wheel alignment at a SEAT Of-
ficial Service. WARNING
Unsuitable handling of the wheels and
t yr

es may lead to sudden tyre pressure los-
ses, to tread separation or even to a blow-
out.

Practical tips
The minimum permitted profile depth 1)
hav e
been r eached when the tyres have worn
down to the wear indicators. Replace the
tyres with new ones ››› .
Changing wheel s ar

ound
To ensure that the wear is equal on all tyres
the wheels should be changed round from
time to time according to the system
››› Fig. 236. The useful life of all the tyres will
then be about the same time. WARNING
The tyres must be replaced at the latest
when the tr ead is w

orn down to the tread
wear indicators. Failure to follow this in-
struction could result in an accident.

design of summer tyres (width, rubber com-
pound, tr ead patt
ern) gives less grip on ice
and snow. This applies particularly to vehicles
equipped with wide section tyres or with
high speed tyres (code letters H, V or Y on
the sidewall).
Only use winter tyres of the correct type ap-
proved for your vehicle. The sizes of these
tyres are specified in the vehicle's documents
(e.g. EC Certificate of Conformity or COC 1)
).
The vehicle documentation varies depending
on the country of residence.
Winter tyres lose a great deal of their proper-
ties when the tread is worn down to a depth
of 4 mm.
The performance of winter tyres is also se-
verely impaired by ageing, even if the tread is
still much deeper than 4 mm.
A code letter indicating the speed limit is
stamped on all winter tyres ››› page 346
.
Vehicles capable of exceeding these speeds
must have an appropriate sticker attached
so that it is visible to the driver. Suitable stick-
ers are available from the SEAT Official Serv-
ice and specialised workshop. Please note
the regulations to this effect in your country.
“All-weather” tyres can also be used instead
of winter tyres. Using winter tyres with V-rating
Please not
e that the generally applicable
240 km/h (149 mph) speed for winter tyres
with the letter V is subject to technical re-
strictions; the maximum permissible speed
for your vehicle may be significantly lower.
The maximum speed limit for these tyres de-
pends directly on the maximum axle weights
for your car and on the listed weight rating of
the tyres being used.
It is best to contact a SEAT Official Service to
check the maximum speed which is permissi-
ble for the V-rated tyres fitted on your car on
the basis of this information. WARNING
Exceeding the maximum speed permitted
f or the wint

er tyres fitted on your car can
cause tyre failure, resulting in a loss of con-
trol of the vehicle – risk of accident. For the sake of the environment
When winter is over, change back to sum-
mer t yr

es at an appropriate moment. In
temperatures above +7°C (+45°F), perform-
ance will be improved if summer tyres are
used. Fuel consumption, wear and noises
while driving will all be reduced. Snow chains
Snow chains must only be fitted t
o the fr
ont
wheels, even on vehicles with four-wheel
drive.
