Driving
●
Never l e
ave the vehicle unattended if the
engine is running.
● Never switch the engine off until the vehi-
cle h
as come to a complete stop. Risk of acci-
dent! CAUTION
● Turnin g the s

teering wheel fully in either
direction when the vehicle is stationary and
the engine is in gear puts the power steering
under great stress. This could lead to noise.
Never leave the steering wheel turned fully in
either direction for more than 15 seconds.
Risk of damage to the power steering system!
● The starter motor may only be used (key
position 3
››› Fig. 173 ›
›› page 154 in the ig-
nition) if the engine is off. Using the starter
motor when the engine is running could dam-
age it.
● Immediately release the ignition key when
the engine st
arts, otherwise damage could be
caused to the starter motor.
● When the engine is cold, you should avoid
high engine speed
s, driving at full throttle
and over-loading the engine before it reaches
operating temperature. Risk of engine dam-
age!
● Do not tow-start the engine. Risk of engine
damag
e! In vehicles with a catalytic convert-
er, fuel that has not been burned could reach
the catalytic converter and catch fire in it.
This would lead to a fault in the catalytic con-
verter. You may use the battery from another vehicle to help you start your engine

● After prolonged and demanding operation
of the engine, when the j
ourney has ended,
do not stop the engine immediately. Let the
engine run at idle for about one more minute.
This will stop the engine from overheating. For the sake of the environment
Do not warm up the engine when the vehicle
i s s

tationary. If possible, move off immediate-
ly after starting the engine. This will help the
engine reach operating temperature more
quickly, reducing the quantity of emissions. Note
● The engine c an on

ly be started with the
original SEAT key.
● Loud running noises may be heard briefly
after c
old-starting the engine. This is normal
and is no cause for concern.
● After the engine has been stopped and the
ignition switc
hed off, the radiator fan may
continue running for around 10 minutes.
● If the engine still does not start after a sec-
ond attempt, the fuel
pump fuse might have
blown. Check it and replace if necessary
››› page 81 or contact your Specialised Serv-
ice.
● You should always engage the steering lock
when you e
xit the vehicle. This will hinder
any attempts at theft. Power steering
The power steering allows you to turn the
st
eerin

g wheel more easily.
If the power steering fails or the engine is off
(towing), it is still possible to turn the vehi-
cle's steering wheel fully. However, you need
more strength to steer the vehicle.

gear position (automatic gearbox). This uses
the force of the engine and the brakes do not
suffer as much. If you still have to brake, do
so intermittently, pressing down repeatedly
on the brake pedal.
● Vehicle modifications (e.g. to the engine,

braking distances – Risk of accident! Brakes
Wear
The r
at
e of

wear of the brake pads depends
on the driving style and on the way in which
the vehicle is used. The brake pads will wear
more quickly if you use your vehicle frequent-
ly in urban traffic and short trips or drive in a
sporty style. Under these demanding condi-
tions, visit your specialised service, even be-
fore the scheduled service date, so that the
thickness of the brake pads can be meas-
ured.
Wet roads or road salt
If brakes are wet or frozen, or if you are driv-
ing on roads which have been gritted with
salt, braking power may set in later than nor-
mal. Dry the brakes as soon as possible by
braking repeatedly. Corrosion
Long period

s of inactivity and little use can
lead to rust on the brake discs and dirt on the
brake pads. Where the brake system is sub-
jected to light stress or in the case of corro-
sion, clean the brake discs by braking fully
several times at a high speed.
Brake system fault
If you notice that the braking distance sud-
denly increases and the brake pedal can be
pressed down more fully, there may be a fault
in the brake system. Visit a specialised serv-
ice immediately and adjust your driving style
to the extent of the damage and to limit the
effect of the brakes.
Low brake fluid level
Insufficient brake fluid could cause faults in
the brake system. The brake fluid level is con-
trolled electronically ››› page 157, Control
lamp.
Brake servo
The brake servo supplements the pressure
you exert on the brake pedal. The brake servo
only works when the engine is running.

Driving
Periodic maintenance
P eriodic
m
aintenance work guarantees that,
before beginning a journey, you will not con-
sume more than the required amount of fuel.
A well-serviced engine gives you the benefit
of improved fuel efficiency as well as maxi-
mum reliability and an enhanced resale val-
ue.
A badly serviced engine can consume up to
10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of
polluting exhaust gases, the engine and the
exhaust gas filtration systems should reach
the optimum operating temperature.
With the engine cold, fuel consumption is
proportionally higher. The engine does not
warm up and fuel consumption does not nor-
malise until having driven approximately four
kilometres (2.5 miles). This is why we recom-
mend avoiding short trips whenever possi-
ble.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an ad-
equate pressure saves fuel. If the tyre pres-
sure is just one bar (14.5 psi/100 kPa) too
low, fuel consumption can increase by as
much as 5%. Due to the greater rolling resist-
ance, under-inflation also increases tyre wear
wear and impairs handling. The tyre pressures should always be checked
when the tyre
s are cold.
Do not use winter tyres all year round as they
increase fuel consumption by up to 10%.
Avoid unnecessary weight
Given that every kilo of extra weight will in-
crease the fuel consumption, it is advisable
to always check the luggage compartment to
make sure that no unnecessary loads are be-
ing transported.
A roof rack is often left in place for the sake
of convenience, even when it is no longer
needed. At a speed of 100 km/h (62 mph)
and 120 km/h (75 mph) your vehicle will use
about 12% more fuel as a result of the extra
wind resistance caused by the roof rack even
when it is not in use.
Save electricity
The engine activates the alternator, which
produces electricity. With the need for elec-
tricity, fuel consumption also increases. Be-
cause of this, always turn off electrical devi-
ces when you do not need them. Examples of
devices that use a lot of electricity are: the
fan at high speeds, the rear window heating
and the seat heaters*. Note
● If y

ou vehicle has Start-Stop, it is not rec-
ommended to switch this function off. ●
It i s

recommended that you close the win-
dows when driving at more than 60 km/h
(37 mph).
● Do not drive with your foot resting on the
clutc
h pedal,, as the pressure can make the
plate spin, more fuel will be used and it can
burn the clutch plate lining, causing a serious
fault.
● Do not hold the vehicle on a hill with the
clutc
h, use the foot brake or hand brake, us-
ing the latter to start. The fuel consumption
will be lower and you will prevent the clutch
plate from being damaged.
● On descents, use the engine brake, chang-
ing to the g
ear that is more suitable for the
slope. Fuel consumption will be “zero” and
the brakes will not suffer. Engine management and emis-

Operation
●
Do not ap p
ly wax underneath the vehicle
around the area of the exhaust system: Fire
hazard! Note
While the control lamps , ,  or  r
e-
m ain lit, ther

e may be engine problems, fuel
consumption may increase and the engine
may lose power. Catalytic converter
An exhaust gas emission control system (cat-
alytic
c
on

verter) that functions perfectly is vi-
tally important for vehicle operation that re-
spects the environment.
Please observe the following indications:
● Refuel only using unleaded petrol in petrol
engine v
ehicles ››› page 202.
● Do not add too much oil to the engine
›››
page 209, Checking engine oil level .
● Do not switch off the ignition while driving.
If y
ou are required to drive in a country where
unleaded fuel is not available, when return-
ing to a country where using a catalytic con-
verter is obligatory, the catalytic converter
must be replaced. CAUTION
● Never c omp

letely empty the tank! An irreg-
ular fuel supply can cause ignition faults,
which can result in damage to a substantial
amount of engine parts and the exhaust sys-
tem.
● Refuelling just once with leaded petrol dis-
able
s the exhaust system! Particulate filter  (diesel
en
gines) The diesel engine particulate filter eliminates
mo
s
t

of the soot from the exhaust gas sys-
tem. Under normal driving conditions, the fil-
ter cleans itself. The diesel particulate filter is
cleaned automatically without need for indi-
cation by the warning lamp . This may be
noticed because the engine idle speed in-
creases and an odour may be detected.
If automatic filter purification cannot be car-
ried out (because only short trips are taken,
for example), soot will accumulate on the fil-
ter and the Diesel particulate filter warning
lamp will  switch on.
Facilitate the automatic filter cleaning proc-
ess by driving in the following manner: drive
for approximately 15 minutes at a minimum
speed of 60 km/h (37 mph) in 4th or 5th gear
(automatic gearbox: gear S). Maintain the en-
gine speed at approximately 2,000 rpm. The
rise in temperature causes the soot on the fil- ter to burn. On completion of the cleaning
the warning l

amp will switch off.
If the lamp  does not turn off, or the three
lamps turn on (particulate filter , fault in
the emission control system  and glow
plugs ), drive the vehicle to a specialised
workshop and have the fault repaired at the
earliest opportunity. WARNING
● Alw a

ys drive according to the road weather
conditions, the terrain and traffic.
● The particulate filter attains very high tem-
peratur
es. Therefore, do not park the vehicle
in places where the exhaust pipe could come
into contact with dry grass or with highly-
flammable materials. Risk of fire! CAUTION
While the warning lamp  is lit
up, the fuel
consumption is high, and in certain condi-
tions, the engine power is reduced. Note
● In order f or the p

articulate filter to burn off
soot in a correct manner, avoid carrying out
frequent short journeys.
● Using diesel fuel with a high sulphur count
can con
siderably reduce the useful life of the
particulate filter. The specialised service pro-
vides information about the countries where
fuel with a high sulphur content is used. 168

Towing bracket device
Trailer weight Trailer weight
The comb
ined
vehicle and trailer must be
balanced. To do so use the maximum permit-
ted towing bracket load. An insufficient
weight exerted by the trailer drawbar on the
ball joint of the towing bracket will have a
negative impact upon the response of the ve-
hicle-trailer assembly on the road.
Weight distribution
Distribute loads in the trailer so that heavy
objects are as near to the axle as possible.
Ensure that the objects do not move.
If the towing vehicle is empty and the trailer
loaded then the load distribution is incorrect.
However, if these conditions cannot be avoi-
ded, drive very slowly.
Tyre pressure values
Correct the tyre pressure in your vehicle to
“total load” ›››
page 218, Service life of
tyres.
Trailer weight
Never exceed the authorised trailer weight
under any circumstances ›››
page 223, Tech-
nical specifications .
The trailer weights listed are only applicable
for altitudes up to 1000 m above sea level.
Due to lower air density, engine power de- creases depending on the increase in alti-
tude, thi
s

also reduces climbing ability,
which requires a reduction of the weight of
the vehicle with a trailer by 10% for every
1000 m increase in altitude. The weight of
the assembly is calculated by adding the ve-
hicle weight (loaded) to the trailer weight
(loaded). Always drive with special care when
towing a trailer.
The towed load and support load information
that is displayed on the towing bracket man-
ufacturers label are only values for the verifi-
cation of the device. The correct figures for
your specific vehicle, which are usually lower
than these figures, are given in the documen-
tation of your vehicle. WARNING
● Exc eedin

g the maximum established load
per axle and the maximum towing bracket
load in addition to the maximum permitted
load or the load of the vehicle + trailer as-
sembly can cause accidents and serious inju-
ries.
● A sliding load can considerably affect the
stab
ility and safety of the vehicle + trailer as-
sembly, resulting in accidents and serious in-
juries. Driving with a trailer
Exterior mirrors
Check
whether

you can see enough of the
road behind the trailer with the standard rear
vision mirrors. If this is not the case, you
should have additional exterior mirrors fitted.
Observe the relevant statutory requirements
of the country you are in.
Headlights
Before starting a journey, also check the
headlight beam settings with the trailer
hitched up. Adjust the headlight range set-
tings if necessary ›››
page 122, Headlight
range control.
Driving speed
For your own safety do not drive faster than
the maximum permitted speed indicated on
the trailer.
At all times, immediately reduce speed if you
detect the slightest swaying movement of the
trailer. Never try to “return the trailer to a
straight position” by accelerating.
Brakes
Brake in due course! If the trailer has an over-
run brake, apply the brakes gently at first and
then, firmly. This will prevent the jerking that
can be caused by locking of trailer wheels.
