Automatic gearbox malfunction
Back-up programme
When automatic gearbox warning and control lamps light up on the instru-
ment panel, there may be a system malfunction ⇒ page 124. In the event of
some faults the automatic gearbox functions using a backup programme.
When the backup programme is activated, it is possible to drive the vehicle,
however, at low speeds and within a selected range of gears.
With the manual gearbox, in some cases it is not possible to drive with all
the gears.
In all cases the automatic gearbox must be checked at a specialised work-
shop.
Automatic gearbox overheating
The automatic gearbox can overheat with a prolonged start up, or when
stopping and starting continuously. This overheating is displayed with a
warning lamp  in the instrument panel. Additionally, an audible warning
can be heard. Stop and let the gearbox cool ⇒ 
.
The vehicle moves forward or back despite having selected a gear range
When the vehicle does not move in the required direction, the system may
not have the gear range correctly engaged. Press the brake pedal and en-
gage the gear range again. If the vehicle still does not move in the required
direction, there is a system malfunction. Seek specialist assistance and
have the system checked.
CAUTION
● When the gearbox is displayed as overheating for the first time, the vehi-
cle must be parked safely or must be driven at a speed of more than 20 km/
h (12 mph).
● When the warning lamp lights up and the audible warning is sounded,
the vehicle must be parked safely and the engine switched off. Let the gear-
box cool down.
● To prevent damage to the gearbox, driving must only be continued when
the warning lamps are no longer lit up. While the gearbox is overheated,
starting up and driving at walking speed should be avoided. 
Recommended gear display
In some vehicles, the recommended gear for reducing fuel consumption is
displayed on the instrument panel display:

Handbrake
Fig. 90 Between the
front seats: Handbrake Using the handbrake
●
Pull firmly in an upwards direction on the handbrake lever while press-
ing the button.
● The handbrake is applied when the control lamp  lights up on the in-
strument panel ⇒ page 135 when the ignition is switched on.
Releasing the handbrake
● Pull gently in an upwards direction on the handbrake lever and press the
lock button ⇒ Fig. 90 (arrow).
● Move the handbrake lever downwards keeping the lock button pressed.
WARNING
The incorrect use of the handbrake may result in a serious accident.
● Never use the handbrake to brake the vehicle except in an emergency.
The braking distance is considerably longer, because braking is only ap-
plied to the rear wheels. Always use the foot brake.
● Never drive with the handbrake gently applied. This can overheat the
brake, affecting the brakes system. This also causes premature wear on
the rear brake pads.
● Never accelerate from the engine compartment with the engine run-
ning and a gear engaged. The vehicle could move, even if the handbrake
is applied.
Note
If the vehicle moves at a speed superior to 6 km/h (4 mph) with the hand-
brake applied, an audible warning is sounded. 
Parking
When parking your vehicle, all legal requirements should be observed. 

Steering Introduction
The power steering* is not hydraulic but electromechanical. The advantage
of this steering system is that it disposes of hydraulic tubes, hydraulic oil,
the pump, filter and other components. The electromechanical system
saves fuel. While a hydraulic system requires oil pressure to be maintained,
electromechanical steering only requires energy when the steering wheel is
turned.
With the electromechanical steering system, the power steering function au-
tomatically adjusts according to the vehicle speed, the steering torque and
the wheel turning angle. The electromechanical steering only works when
the engine is running.
Additional information and warnings:
● Start and stop the engine ⇒ page 119
● Vehicle battery ⇒ page 193
● Tow-starting and towing away ⇒ page 276
WARNING
If the power steering is not working then the steering wheel is much
more difficult to turn and the vehicle more difficult to control.
● The power steering only works when the engine is running.
● Never allow the vehicle to move when the engine is switched off.
● Never remove the key from the ignition if the vehicle is in motion. The
steering may lock and it will not be possible to turn the steering wheel.

Cruise control* (Cruise control system - CCS)
Introduction
The cruise control system (CCS) is able to individually maintain the set
speed when driving forwards from approx. 20 km/h (12 mph).
The CCS only slows down by reducing the accelerator but not by braking
⇒ 
.
Additional information and warnings:
● Changing gear ⇒ page 124
● Accessories, parts replacement, repairs and modifications ⇒ page 222
WARNING
Use of the cruise control could cause accidents and severe injuries if it is
not possible to drive at a constant speed maintaining the safety distance.
● Do not use the cruise control in heavy traffic, if the distance from the
vehicle in front is insufficient, on steep roads, with several bends or in
slippery circumstances (snow, ice, rain or loose gravel), or on flooded
roads.
● Never use the CCS when driving off-road or on unpaved roads.
● Always adapt your speed and the distance to the vehicles ahead in
line with visibility, weather conditions, the condition of the road and the
traffic situation.
● To avoid unexpected operation of the cruise control system, turn it off
every time you finish using it.
● It is dangerous to use a set speed which is too high for the prevailing
road, traffic or weather conditions.
● When travelling down hills, the CCS cannot maintain a constant
speed. The vehicle tends to accelerate under its own weight. Select a
lower gear or use the brake pedal to slow the vehicle.

In natural gas engines
The warning lamp  lights up when both fuel types (petrol and natural gas)
have reached reserve level.
The warning lamp  lights up when the vehicle is running in natural gas op-
erating mode. The warning lamp 
switches off when the natural gas is exhausted. The
engine changes to operate with petrol.
Problem: If the vehicle is left parked for a long time immediately after refuel-
ling, 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 pressure in the gas tank for techni-
cal reasons after a cooling phase immediately after refuelling.
WARNING
Driving with insufficient fuel reserve could result in the vehicle breaking
down in traffic and a serious accident.
● If the fuel level is too low then the fuel supply to the engine can be-
come irregular especially 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 assistance sys-
tems including braking assistance will stop working.
● Always refuel when there is only one quarter of the fuel tank left to
avoid running out of fuel.
CAUTION
● Always pay attention to any lit lamps and to the corresponding descrip-
tions and instructions to avoid damage to the vehicle.
● Never run the fuel tank completely dry. An irregular fuel supply may lead
to ignition faults and unburnt fuel could enter the exhaust system. This
could damage the catalytic converter.
Note
The arrow next to the fuel pump symbol on the instrument panel ⇒ Fig. 105
indicates the side of the vehicle on which the fuel tank plug is located. 

Engine coolant Introduction
Never work on the engine cooling system or if you are not familiar with the
operations to be carried out, the applicable safety standards and especially
if you do not have the instruments, liquids and tools necessary ⇒ 
! In
such a case, have any work carried out by a Specialised workshop. SEAT rec-
ommends visiting a Technical Service.
Negligent work can cause serious injury.
Additional information and warnings:
● Working in the engine compartment ⇒ page 180
● Accessories, parts replacement, repairs and modifications ⇒ page 222
WARNING
Engine coolant is toxic!
● Only keep engine coolant in its original container, tightly shut and in
a safe place.
● Never store engine coolant in empty food containers or bottles as
other people may accidentally drink it.
● Always keep engine coolant out of reach of children.
● Ensure that the proportion of engine coolant additive corresponds to
the lowest outside temperature to which the vehicle will be exposed.
● If the outside temperature is extremely low, the engine coolant could
freeze causing the vehicle to stop. As this would also cause the heating
to stop working, vehicle occupants without sufficient clothing could
freeze.
For the sake of the environment
Coolants and additives can contaminate the environment. Collect any spilt
fluids in suitable containers and dispose of in accordance with legislation
and with the utmost respect for the environment. 
