Checking levels Fig. 309
Diagram for the location of the various el-
ements. From time to time, the levels of the different
fluids in the v

ed. Never
fill with incorrect fluids, otherwise serious
damage to the engine may be caused.

Wheels
If the rims and tyres have received a heavy
impact or hav e been damaged, hav
e them
check
ed and, if required, replaced at a speci-
alised workshop.
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.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the di-
rection of rotation on single drive tyres. Al-
ways note the direction of rotation indicated
when mounting the wheel. This guarantees
optimum grip and helps to avoid aquaplan-
ing, excessive noise and wear.
Retrofitting accessories
If you wish to change or fit wheels, rims or
wheel trims, we recommend that you consult
with a SEAT Official Service centre for advice
regarding current techniques. Service life of tyres

Practical tips
Do not forget the spare wheel when checking
the t yr
e pr
essures: Keep this spare wheel in-
flated to the highest pressure required for the
road wheels.
In the case of a minimised temporary spare
wheel (125/70 R16 or 125/70 R18) inflate to a
pressure of 4.2 bar as indicated on the tyre
pressure label on the fuel tank flap.
Driving style
Fast cornering, heavy acceleration 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

The SEAT deal

ership or a specialised work-
shop records Service receipts in a central
system. Thanks to this comprehensive docu-
mentation of the service history, it is possible
to reproduce the services performed any
time. SEAT recommends requesting a Service
receipt after every service carried out con-
taining all the services carried out on the sys-
tem.
Whenever there is a new service the receipt is
replaced with a current one.
The Digital Maintenance Plan is not avail-
able in some markets. In this case, your
SEAT dealer will inform you about the cur-
rent documentation of the work. Service works
