Driving
Hill driving assistant* Fig. 179
Related video This function is only included in vehicles with
ESC.
The hi l
l driving assistant helps the driver to
move off and upward on a hill when the vehi-
cle is stationary.
The system maintains brake pressure for ap-
proximately two seconds after the driver
takes his foot off the brake pedal to prevent
the vehicle from lurching backward when it is
started. During these 2 seconds, the driver
has enough time to release the clutch pedal
and accelerate without the vehicle moving
and without having to use the handbrake,
making start-up easier, more comfortable
and safer.
These are the basic operation conditions:
● being on a ramp or hill/slope,
● driver door closed,
● vehicle completely stationary,
● engine running and foot on the brake, ●
bes ide

s having a gear engaged or being in
neutral for manual gear change and with the
selector lever at position S, D or R for an au-
tomatic gearbox.
This system is also active when reversing up-
hill. WARNING
● If y

ou do not start the vehicle immediately
after taking your foot off the brake pedal, the
vehicle may start to roll back under certain
conditions. Depress the brake pedal or use
the hand brake immediately.
● If the engine stalls, depress the brake ped-
al or u
se the hand brake immediately.
● When following a line of traffic uphill, if you
want t
o prevent the vehicle from rolling back
accidentally when starting off, hold the brake
pedal down for a few seconds before starting
off. Note
The Official Service or a specialist workshop
can t el

l you if your vehicle is equipped with
this system. Manual gearbox

ith a manual gearbox Read the additional information carefully
›› ›

 page 49
Certain versions of the model may include a
6-speed manual gearbox, and its diagram is
shown on the gearbox lever.
The reverse gear can only be engaged when
the car is stationary. When the engine is run-
ning and before engaging this gear, wait
about 6 seconds with the clutch pressed
down thoroughly in order to protect the gear-
box.
The reverse lights switch on when the reverse
gear is selected and the ignition is on. WARNING
● When the engine i s

running, the vehicle
will start to move as soon as a gear is engag-
ed and the clutch released.
● Never select the reverse gear when the ve-
hicle i
s in motion. Risk of accident. Note
● Do not r e

st your hand on the gear lever
while driving. The pressure of your hand
could cause premature wear on the selector
forks in the gearbox. » 187

The v
ehic

le is fitted with a 13-pole power
socket for the electrical connection between
the trailer and the vehicle. If the system de-
tects that a trailer has been connected elec-
trically, the electrical equipment on the trailer
will receive voltage through this connection.
Pin 9 has a permanent live. This powers, for
example, the trailer's interior lighting. Pin 10
is only powered when the engine is running.
The charge wire (pin 10) charges, for exam-
ple, a caravan battery.
Pin 9 and 10 should not be connected to
each other to avoid discharging or damaging
the vehicle's battery.
The earth wires, pin 3, pin 11 and pin 13,
should never be connected to each other to
avoid overloading the electrical system.
If the trailer has a 7-contact connector , you
will need to use an adapter cable. In this case
the function corresponding to pin 10 will not
be available. Trailer maximum electricity consumption

The position of the battery is shown in the
c orr
e
sponding engine compartment diagram
››› page 275.
The “magic eye” indicator, located on the top
of the battery changes colour, depending on
the charge state and electrolyte level of the
battery.
There are two different colours:
● Black: correct charge status.
● Transparent/clear yellow: the battery must
be repl
aced. Contact a specialised workshop.
Charging or changing the battery The battery is maintenance-free and is
c
hec
k

ed during the inspection service. All
work on the vehicle battery requires special-
ist knowledge.
If you often drive short distances or if the ve-
hicle is not driven for long periods, the bat-
tery should be checked by a specialised
workshop between the scheduled services.
If the battery has discharged and you have
problems starting the vehicle, the battery
might be damaged. If this happens, we rec-
ommend you have the vehicle battery
checked by a Technical Service where it will
be re-charged or replaced. Charging the battery
The vehic

le battery should be charged by a
specialised workshop only, as batteries us-
ing special technology have been installed
and they must be charged in a controlled en-
vironment.
Replacing a vehicle battery
The battery has been developed to suit the
conditions of its location and has special
safety features.
Genuine SEAT batteries meet the mainte-
nance, performance and safety specifications
of your vehicle. WARNING
● We r ec

ommend you use only maintenance-
free or cycle free leak-proof batteries which
comply with standards T 825 06 and
VW 7 50 73. This standard applies as of
2001.
● Before starting any work on the batteries,
you mus
t read and observe the warnings
››› in Symbols and warnings on handling
the batt er

y on page 281. For the sake of the environment
Batteries contain toxic substances such as
su lphuric

acid and lead. They must be dis-
posed of appropriately and must not be dis-
posed of with ordinary household waste. Wheels
Wheel s
and ty

res
General notes Avoiding damage
– If you have to drive over a kerb or similar
ob s

tacle, drive very slowly and at a right
angle.
– Keep grease, oil and fuel off the tyres.
– Inspect the tyres regularly for damage
(cuts, c r

acks or blisters, etc.). Remove any
foreign objects embedded in the treads.
Storing tyres
– When you remove the tyres, mark them in
order to m

aintain the same direction of ro-
tation when they are installed again.
– When removed, the wheels and/or tyres
should be s

tored in a cool, dry and prefera-
bly dark location.
– Store tyres in a vertical position, if they are
not fitted on wheel

rims.

Wheels
Service life of tyres Fig. 240
Tyre tread wear indicators. Fig. 241
Diagram for changing wheels. The useful life of tyres is dependent on tyre
pr
e
s
sure, driving style and fitting.
Wear indicators
The original tyres on your vehicle have
1.6 mm high “tread wear indicators”
››› Fig. 240, running across the tread. De- pending on the make, there will be 6 to 8 of
them evenly

spaced around the tyre. Mark-
ings on the tyre sidewall (for instance the let-
ters “TWI” or other symbols) indicate the po-
sitions of the tread wear indicators. The mini-
mum tread depth required by law is 1.6 mm
(measured in the tread grooves next to the
tread wear indicators). Worn tyres must be re-
placed. Different figures may apply in export
countries ››› .
T y
r

e pressure
Incorrect tyre pressure causes premature
wear and could cause tyre blow-out. For this
reason, the tyre pressure should be checked
at least once per month ››› page 284.
Driving style
Fast cornering, heavy acceleration and hard
braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more
than the rear ones it is advisable to change
them around as shown ››› Fig. 241. The use-
ful life of all the tyres will then be about the
same time.
Wheel balance
The wheels on new vehicles are balanced.
However, various factors encountered in nor-
mal driving can cause them to become unbal-
anced, which results in steering vibration. Unbalanced wheels should be rebalanced, as
they otherw

ise cause excessive wear on
steering, suspension and tyres. A wheel must
also be rebalanced when a new tyre is fitted.
Incorrect wheel alignment
Incorrect running gear alignment causes ex-
cessive tyre wear, impairing the safety of the
vehicle. If tyres show excessive wear, you
should have the wheel alignment checked by
a Technical Service. WARNING
There is a serious danger of accidents if a tyre
bur s

ts during driving!
● The tyres must be replaced at the latest
when the trea
d wear indicators are worn
››› page 285. Failure to follow this instruction
could result in an accident. Worn tyres do not
grip well at high speeds on wet roads. There
is also a greater risk of “aquaplaning”.
● At continuously high speeds, a tyre with in-
sufficient
pressure flexes more. This causes it
to overheat. This can cause tread separation
and tyre blow-out. Risk of accident. Always
observe the recommended tyre pressures.
● If tyres show excessive wear, you should
have the ru
nning gear checked by a Technical
Service.
● Keep chemicals such as oil, fuel and brake
fluid awa
y from tyres.
● Damaged wheels and tyres must be re-
plac
ed immediately! » 285
