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.

Note
If the City Safety Assist function activates a brake, the brake pedal range is
reduced. This makes the brake pedal seem “harder”.
Note
Automatic brake intervention by the City Safety Assist function can be can-
celled by pressing the clutch pedal, the accelerator pedal or by a corrective
intervention.
Note
During the automatic braking by the City Safety Assist function you may
hear unusual noises. This is normal and is produced in the brakes system. 
Warning and control lamps
The City Safety Assist function is switched on every time the ignition is
switched on. No special indication is produced.
If the City Safety Assist function is switched off, functions or there is an error
in the system, this will be shown by a control lamp on the instrument panel
display.

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. 

Note
● The filling nozzles of natural gas pumps can differ in the way they are
operated. If you are unacquainted with the pump, it is advisable that a
member of staff of the service station performs the refuelling operation.
● Noises heard when refuelling are normal and do not indicate the pres-
ence of a fault in the system.
● The vehicle natural gas system is prepared both for refuelling with a
small compressor (slow refuel) and a large compressor (fast refuel) in natu-
ral gas service stations. 

In the engine compartment
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. 
