Operation
(25 mph) in fourth gear and at 50 km/h
(31 mph) in fifth gear.
In addition, “skipping” gears when shifting
up helps to save fuel, weather and traffic
conditions permitting.
Do not wait until the last moment before
changing gear. Only use first gear when you
move off and change to second gear quickly.
Avoid the kick-down function in vehicles with
automatic gearbox.
Vehicles with a gear display help to achieve
an economical driving style as the display in-
dicates the best moment to change gear.
Let the vehicle roll
If you take your foot off the accelerator, the
fuel supply is stopped and consumption is
reduced.
Allow the vehicle to roll without accelerating,
for example when approaching a red traffic
light. However, if the vehicle is rolling too
slowly or the distance is too long, the clutch
pedal should be pressed to declutch. The en-
gine will then operate at idle speed.
If the vehicle is going to be at a standstill for
a period of time, switch off the engine; for ex-
ample, while waiting at a level crossing.
Think ahead and “flow” with the traffic
Frequent acceleration and braking considera-
bly increase fuel consumption. If you think ahead as you drive and keep a safe distance
from the vehicle in front, it is possible to slow
down by simply lifting your foot off the accel-
erator. This eliminates the need for constant
braking and acceleration.
Calm and steady driving
Constancy is more important than speed: The
more you drive at a constant speed, the lower
the fuel consumption.
When driving on the motorway, it is more effi-
cient to drive at a constant and more moder-
ate speed than to be continuously accelerat-
ing and braking. As a general rule, you will
reach your destination just as quickly when
you drive at a constant speed.
The cruise control function helps you to ach-
ieve a constant style of driving.
Moderate use of additional devices
It is important to travel in comfort, but con-
venience systems should be used ecological-
ly.
Some equipment, when connected, increase
fuel consumption considerably, for example:
●
Air conditioning cooling system: If the air
conditioning system is required to cool to
significantly lower temperatures than the true
outside temperature, it will require a large
amount of energy from the engine. Therefore,
we recommend that the selected temperature for the vehicle is not too different to the out-
side temperature. It is a good idea to air the
vehicle before starting your journey and to
drive a short distance with the windows
open. Then you can close the windows and
switch on the air conditioning. Keep windows
closed when travelling at high speeds. Driv-
ing with the windows open increases fuel
consumption.
●
Switch off the seat heating when the seats
have warmed up.
● Switch off the heated rear window when it
is not moist or covered in ice.
Avoid short journeys
Fuel consumption is much higher when the
engine is cold, immediately after it has been
started. It takes a few kilometres of driving
for the engine to warm up and to normalise
consumption.
The engine and catalytic converter need to
reach their proper working temperature in or-
der t o minimi
se fuel consumption and emis-
sions. The ambient temperature has a deci-
sive influence.
Fig. 84
shows the difference in consumption
for the same journey at +20 °C (+68 °F) and
at -10 °C (+14 °F).
Therefore, unnecessary short journeys
should be avoided. Try to combine trips.

Driver assistance systems
● Will the navigation system fitted at the fac-
tory operate correctly in the destination coun-
try with the available navigation data?
● Are special tyres required in the destination
country? CAUTION
SEAT does not accept liability for any damage
to the vehicle due to the use of a lower quali-
ty fuel, an inadequate service or the non-
availability of genuine spare parts. Driving along flooded roadways
To prevent damage to the vehicle when driv-
ing through water, for example, along a floo-
ded road, please observe the following:
● Check the depth of the water before enter-
ing the flooded zone. The water should never
come above the lower edge of the bodywork
››› .
● Do not drive faster than a pedestrian.
● Do not stop in the water, use reverse gear
or switch off the engine.
● Oncoming traffic will cause waves which
raise the level of the water, making it difficult
to cross the water.
● Disconnect the Start-Stop system whenever
crossing water. WARNING
When driving through water, mud, melted
snow, etc., please remember that due to
damp or frozen brake discs and shoes in win-
ter, the braking effect may be delayed, there-
fore the required braking distance is greater.
● “Dry the brakes and remove ice” by braking
carefully. Ensure that you are not endanger-
ing other road-users or breaking traffic regu-
lations in the process.
● After driving through water, avoid sudden
sharp manoeuvres. CAUTION
● Driving through flooded areas may severely
damage vehicle components such as the en-
gine, transmission, drive train or electrical
system.
● Never drive through salt water as salt cau-
ses corrosion. Always rinse any parts of the
vehicle which have been in contact with salt
water. Driver assistance systems
Braking and stability systems Brake assist systems The assisted braking systems ESC*, ABS,
EBV, BAS, ASR, TC and EDL only operate when
the ignition is switched on. They contribute
significantly to increasing active safety.
Electronic stability control (ESC)*
ESC* reduces the risk of skidding and increa-
ses the vehicle stability by braking individual
wheels under specific driving conditions.
ESC* detects critical handling situations,
such as understeer, oversteer and wheelspin
on the driven wheels. The system stabilises
the vehicle by braking individual wheels or
by reducing the engine torque.
The ESC* has limits. It is important to realise
that ESC* is also subject to the laws of phys-
ics. ESC* will not be able to deal with all sit-
uations with which drivers may be faced. For
example, if the road surface changes sudden-
ly then ESC* will not be useful in all cases. If
the vehicle suddenly enters a section cov-
ered by water, mud or snow then ESC* will
not provide assistance in the same way as on
dry ground. If the vehicle loses its grip on the
ground and moves on a film of water (“aqua-
planing”), the ESC* will not be able to help

Operation
the driver control the vehicle due to the loss
of adherence with the road surface prevent-
ing braking and steering. If the vehicle is
driven through series of bends at high
speed, the ESC* will not always be as effec-
tive: the vehicle reaction to aggressive driv-
ing is not the same as at reduced speeds.
Adjust your speed and driving style to suit
visibility, and weather, road and traffic condi-
tions. ESC* cannot push the limits of the laws
of physics; improve the transmission availa-
ble or maintain the vehicle on the road if a
lack of driver attention creates an inevitable
situation. Otherwise, ESC* assists in main-
taining vehicle control in extreme situations
and uses the movements of the steering
made by the driver to maintain the vehicle
moving in the desired direction. If the vehicle
is driven at such a speed that it will leave the
road before ESC* can intervene then the sys-
tem cannot provide assistance.
The ABS, BAS, ASR and EDL systems are in-
corporated into the ESC*. The ESC* is always
on 1)
.
Anti-lock brake system (ABS)
ABS can prevent the wheels from locking dur-
ing braking until just before the vehicle stops
thus helping the driver to steer the vehicle
and maintain control. This means that, even during full braking, the risk of skidding is re-
duced:
● Press and hold the brake pedal fully. Do not
remove your foot from the brake pedal or re-
duce braking force!
● Do not “pump” the brake pedal, or reduce
braking force!
● Maintain vehicle direction when braking
fully.
● When the brake pedal is released or when
the brake force is reduced, ABS is turned off.
ABS control can be observed by vibration of
the brake pedal and noise. You should never
e xpect
the ABS to reduce the braking dis-
tance under
any circumstances. This distance
will increase when driving on gravel, recent
snow or on icy or slippery ground.
Brake assist system (BAS)
The brake assist system may reduce the re-
quired braking distance. The brake assist
system boosts the braking force if you press
the brake pedal quickly in an emergency. As
a result, the braking pressure increases rap-
idly, the braking force is multiplied and the
braking distance is reduced. This enables the
ABS to be activated more quickly and effec-
tively. ¡Do not lift your foot off the brake pedal!
When the br
ake pedal is released or when
the brake force is reduced, braking assist au-
tomatically turns off the brake servo.
Traction control system (ASR) or Traction
Control (TC)
In the event of wheelspin, the traction control
system ASR or TC reduces the engine torque
to match the amount of grip available. The
ASR or TC makes some situations easier, for
example, when starting, accelerating or go-
ing uphill, even in unfavourable road condi-
tions.
Electronic differential lock system (EDL)
EDL is available when driving in straight lines
under normal conditions. When the EDL de-
tects wheelspin, it brakes the spinning wheel
and directs the power to the other one. To
prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automati-
cally if subjected to excessive loads. The EDL
will switch on again automatically when the
brake has cooled down. WARNING
Driving at high speed on icy, slippery or wet
ground can result in loss of vehicle control 1)
Depending on the version.

Problem:
if the vehicle is left parked for a
long time just after refuelling, the gas level
indicator does not accurately indicate the
same level shown after refuelling when the
vehicle is started up again. This is not due to
a leak in the system, but to a drop in pres-
sure in the gas tank for technical reasons af- ter a cooling phase immediately after refuel-
ling. WARNING
Driving with insufficient fuel reserve could re-
sult in the vehicle breaking down in traffic
and a serious accident.
● If the fuel level is too low then the fuel sup-
ply to the engine can become irregular espe-
cially on slopes.
● If the engine “is choked” or stalls due to
lack of or irregularity of the fuel supply, the
power steering as well as all of the driver as-
sistance systems including braking assis-
tance will stop working.
● Always refuel when there is only one quar-
ter of the fuel tank left to avoid running out of
fuel. CAUTION
● Always pay attention to any lit control
lamps and to the corresponding descriptions and instructions to avoid damage to the vehi-
cle.
● Never run the fuel tank completely dry. An
irregular fuel supply may lead to ignition
faults and unburnt fuel could enter the ex-
haust system. This could damage the catalyt-
ic converter. Note

Advice
●
Never work under the vehicle if it has not
been immobilized. If you must work under-
neath the vehicle with the wheels in contact
with the ground then it should be parked on
flat ground, the wheels should be prevented
from moving and the key should be removed
from the ignition.
● 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!. The jack is not intended for this kind of
work and its failure could lead to severe inju-
ries.
● Disconnect the Start-Stop system. WARNING
The engine compartment is a dangerous area
capable of causing serious injury.
● For all type of work, always take the utmost
precautions, work carefully and note the gen-
eral safety standards in force. Never take per-
sonal risks.
● Never work on the engine or in the engine
compartment if you are not familiar with the
necessary operations. If you are not sure
about procedures then visit a specialised
workshop to carry out the necessary work.
Working incorrectly can cause serious inju-
ries.
● Never open the bonnet if you see steam or
coolant escaping from the engine compart-
ment. This may cause serious burns. Always
wait until you cannot see or hear the sound of steam or coolant coming from the engine
compartment.
●
Always allow the engine to cool down be-
fore opening the bonnet.
● Contact with hot elements of the engine
and the exhaust system can cause burns.
● Once the engine has cooled, follow the in-
structions below before opening the bonnet:
– Engage the handbrake and place the gear
selector lever in N or the gear stick in
neutral.
– Remove the key from the ignition.
– Keep children away from the engine com-
partment and never leave them unsuper-
vised.
● When the engine is warm or hot, the cool-
ing system is pressurised. Do not unscrew
the cap on the expansion tank when the en-
gine is hot. Otherwise, coolant may spray out
under pressure causing burns and serious in-
jury.
– After cooling, carefully and slowly un-
screw the cap anticlockwise, gently
pressing down on it.
– Always protect your face, hands and arms
from hot coolant and steam using a large,
thick cloth.
● When refilling liquids, avoid spilling them
on parts of the engine and the exhaust sys-
tem. Spilled liquids could cause a fire. WARNING
The high voltages of the electrical system can
give electric shocks as well as causing burns
and serious injury and possibly even death!
● Never cause short circuits in the electrical
system. The battery could explode.
● To minimise the risk of electric shock and
serious consequences while the engine is
running or starting the engine, note the fol-
lowing:
– Never touch the electrical wiring of the
ignition system. WARNING
In the engine compartment, there are rotat-
ing parts that could cause serious injury.
● Never place your hands directly on or near
the radiator fan. Touching the rotor blades
could seriously harm you. The ventilator
works according to the engine temperature
and could start suddenly even when the igni-
tion is turned off and the key is removed.
● If any work has to be performed when the
engine is started or with the engine running,
there is an additional, potentially fatal, safety
risk from rotating parts, such as the drive
belts, alternator, radiator fan, etc., as well as
from the high-voltage ignition system. Al-
ways work with the utmost caution.
– Always make sure that no parts of your
body, jewellery, ties, loose clothing and
long hair can be trapped by the rotating 144
